CONSULTED DEPARTMENTS AND AGENCIES The following departments, agencies, and individuals were advised of this application. A. Community Development Review Committee (CDRC), consisting of the Federal Way Community Development Services Planning and Building Divisions; Public Works Engineering and Traffic Divisions; Parks Recreation and Cultural Resources Department; South King Fire and Rescue; Lakehaven Utility District; and Federal Way Public Schools. CDRC comments have been incorporated into this report where applicable. B. All property owners within 300 feet of the site were mailed notices of the application as required by the Subdivision code, as well as the Mitigated Determination of Nonsignificance (MDNS) as required by the State Environmental Policy Act (SEPA) and FWCC Chapter 18, "Environmental Protection." The site was also posted and notices published in the newspaper and on the City's official notice boards. Four comment letters were submitted in response to the August 11, 2007, Notice of Application. Two of the letters had return addresses on them, and two were submitted as anonymous comments. Following revisions to the preliminary plat application, the City responded to the parties that provided comments on the design of the plat on October 28, 2008, and November 4, 2008. III. STATE ENVIRONMENTAL POLICY ACT (SEPA) A. The City of Federal Way issued a Mitigated Environmental Determination of Nonsignificance (MDNS) for the proposed action on October 4, 2008. This determination was based on review of information in the project file, including the environmental checklist and staff evaluation of the Staff Evaluation File 07-103897-00-SU/m�.I.n. 47633 Steel Lake Crest Preliminary Plat Page 3 environmental checklist for Steel Lake Crest Preliminary Plat, resulting in the conclusion that the proposal would not result in probable significant adverse impacts on the environment. B. The comment period for the MDNS concluded on October 20, 2008. One comment letter was received in response to the environmental determination. The City replied to this comment letter dated October 20, 2008. The applicant provided a response to the MDNS as well. The appeal period ended on November 3, 2008, with no appeals to the City's environmental decision. The environmental decision is incorporated as though set forth in full. IV. NATURAL ENVIRONMENT A. Soils — The Subsurface Exploration and Geotechnical Engineering Report, prepared by Jason Engineering & Consulting Business, Inc, and dated June 20, 2007, stated that "the western portion of the site consisted of Alderwood gravelly sandy loam (AgB) soils. Typical Alderwood soils are moderately well drained, undulating to hilly soils that have dense, very slowly permeable glacial till at a depth of 20 to 40 inches; on uplands and terraces formed under conifers in glacial deposits. These soils are nearly level and moderately well drained. Water moves across the substratum in winter. Areas are irregular in shape and slopes range from 0 to 6 percent. Runoff is slow and the erosion hazard is slight. The geology of the eastern portion of the site consists of Alderwood gravelly sandy loam (AgC). Soil profiles are similar in type except permeability is moderately rapid in the surface layer and subsoil. However, it is very slow within the cemented layer and dense glacial till. A perched water table is as high as 18 to 36 inches at times from January through March. Runoff is slow to medium and erosion hazard is moderate." The property slopes gently from west to east. B. Topography, Slopes — The Technical Information Report & Preliminary Drainage Report states that the site naturally slopes from the southwest corner to the northeast corner. There is an approximate drop of 70 feet across the site, with an average slope of 9.3%. There are a few small areas where the average slope exceeds 40%. The majority of these steep slopes are near the existing houses that have slopes up to 40% and are the result of prior grading activities. The slopes on the south edge of the site are typically 15% or greater. C. Vegetation — The geotechnical report identifies existing vegetation as primarily deciduous trees with some large evergreen trees located on the east side of the property. There are also vine maples, cedar trees, blackberry bushes, and nettles. Preliminary plat applications are subject to submittal and approval of a tree retention plan and landscape plan pursuant to FWCC Section 20-186. City policy and FWCC Section 20-179 states that "existing mature vegetation shall be retained to the maximum extent possible, with site clearing limited to plat infrastructure improvements, such as streets, drainage, utilities, usable open space, and related improvements. Retained significant trees located outside of plat infrastructure areas would be regulated under FWCC Section 22-1568, "Significant Trees," and addressed at the time a building permit is applied for. That section further states that "lots created on slopes of 15% or greater shall minimize grading and shall not result in extensive use of retaining walls. Slopes are to be measured in their natural state." The applicant proposes to do mass grading on the site, resulting in the clearing, grading, and removal of a majority of the significant trees and other vegetation on site. There are over 200 Staff Evaluation File 07-103897-00-SU/na. I D. 47633 Steel Lake Crest Preliminary Plat Page 4 trees on the site, but not all of them are considered "significant trees." A Landscape Plan (L-1) and Tree Retention Plan (L-2) were submitted by the Roper Company, last revised submittal was submitted on August 4, 2008, but the plan was dated May 13, 2008. The plan and retention report identified that there are eighty seven (87) significant trees located on the subject site.' Pursuant to the provisions of FWCC Section 22-1568, removal of more than 75 percent of the significant trees requires replacement in the amount of 25 percent of the existing significant trees. The applicant proposes to retain nineteen (19) of the significant trees and provide tree replacement through installation of three (3) replacement trees at the time of planting, and further proposes to plant eight (8) additional trees on some of the lots within the preliminary plat site. The proposal will just meet the minimum required percentage of tree preservation and replacement, but the mass grading project will remove most of the internal trees and a majority of the trees on the east side of the parcel. As discussed in section VI.E, Grading, below, City staff is recommending denial of the proposed preliminary plat and the proposed mass clearing and grading of the site. D. Stormwater Runoff— Development of the site will create additional runoff from new impervious surfaces such as streets, driveways, and rooftops. The storm drainage facilities are being designed in accordance with the 1998 King County Surface Water Design Manual (KCSWDM), which is currently adopted by the City. The subject site is required to meet the criteria for Level 1 Flow Control and Basic Water Quality standards as described in the 1998 KCSWDM. The Preliminary Technical Information Report (TIR), with Preliminary Drainage Review prepared by Schweikl and Associates, PLLC, dated July 2007 and revised May 2008 proposes to meet the requirements for flow control and water quality by utilizing a combined detention and wet pond, as allowed under the KCSWDM. E. Wildlife and Habitat — The applicant noted in the SEPA checklist that deer and songbirds exist on the subject property, that the planting of native vegetation on the site will enhance wildlife habitat opportunities, and that no threatened or endangered species are known to be on or near the subject site. F. Steel Lake — Steel Lake is classified as a shoreline of the state and is located within 200 ft. of the proposed preliminary plat and is regulated by the FWCC, Section 18. Development projects within 200 ft. of a shoreline of the state are often required to apply for a Shoreline Substantial Development Permit, in addition to the underlying permit action. However, the applicant submitted a request to the Director of Community Development in 2007 for an exemption from the substantial development process stating that the potential impacts to the shoreline were very minimal as only the half street frontage improvements being required by the City and located at the northwest corner of the parcel was within 200 ft. of the shoreline. Of that area, 289 sq. ft., over half of the area would be paved dedicated right-of-way and most of the remaining area would be a landscaping buffer. The exemption was granted as requested on May 10, 2007. G. Noise — The subject property is adjacent to the Interstate-5 right-of-way. The applicant was asked to submit a Noise Evaluation to determine impacts of noise from the highway on proposed residences. The applicant submitted the Environmental Noise Review, prepared by SSA A significant tree is defined in the FWCC as a tree that is in good health, not detrimental to the community, and at least 12 inches in diameter 4.5 feet above the ground, not includini red alder, cottonwood, poplar, or big -leaf maple. Staff Evaluation File 07-103897-00-SU/Doc. I D. 47633 Steel Lake Crest Preliminary Plat Page 5 Acoustics, LLP, dated June 1, 2007. The review identified that the outside noise levels under HUD standards for residential development, should not exceed an Ldn of 65 dBA; without additional noise reduction incorporated into the construction. The testing done on the property identified that for the Day -Night Average Noise Levels measured in the area, the acceptable Ldn was higher than that recommended by HUD, therefore mitigation was required. The two options recommended to mitigate the noise from Interstate 5 were: 1) provide above - standard exterior envelope construction mitigation; or, 2) construct a noise barrier. The applicant contacted Washington State Department of Transportation to inquire whether there were any future plans to construct a noise barrier along this length of highway. The WSDOT staff person did not confirm any plans to build such a barrier. Therefore, in subsequent correspondence, the applicant identified a preference for incorporating noise reduction standards into the construction of future homes. The proposed mitigation by SSA Acoustics, LLP was, therefore, incorporated into the mitigated SEPA determination. V. NEIGHBORHOOD CHARACTERISTICS A. Vicinity — The property is situated in the central portion of the City in an already developed single-family residential area. The site contains three older single-family residences, a shed, and a swimming pool. The properties are located south of 308`b with 28`h Avenue South bordering the west side and the Interstate 5 right-of-way corridor on the east side. Single-family residences border the property to the north, west, and south. There are many significant trees along the west side of the property, in the center and on the east edge. VI. GENERAL DESIGN A. Density — The total site area is 294,910 sq. ft, or 6.77 acres. Of that area, 61,290 sq. ft. will be dedicated to right-of-way and road improvements, 18,449 sq. ft. will be developed for storm drainage facilities, 4,561 sq. ft. will be developed into landscaping tracts, and 3,661 sq. ft. will be developed as a pedestrian pathway. Of the developable land, 4.75 acres, 28 lots could be built on the site of the proposed plat provided all other requirements of the FWCC are met. B. Lot Size — The underlying zoning is RS-7.2, which requires a minimum of 7,200 sq. ft. per lot. As shown on the preliminary plat map, Sheet PP1, prepared by Schweikl & Associates, lots range in size from 7,203 sq. ft. to 8,995 sq. ft. The land area excludes land set aside for roads, storm drainage pond, open space, and a pedestrian pathway. The plat meets the minimum standard necessary for lot sizes. C. Lot Layout — The lots are arranged around an internal loop road that accesses off of 28'h Avenue South. There are six lots configured within the center of the road loop. All lots will access off of the internal road, with no direct access onto 28"' Avenue South. An 8-foot-wide pedestrian pathway will be constructed along the north boundary of proposed Lot 28 and extend to Military Road South. The pedestrian pathway will be paved and will have lighting, landscaping, and a fence along the side. D. Parks & Open Space — FWCC 20-156(b) requires that 15% of the land be set aside for open space. Of the total land area for this plat, 44,236.5 sq. ft. is required to meet this requirement. The applicant is proposing to install a pedestrian pathway and three landscaping buffer areas, for Staff Evaluation File 07-103897-00-SU/nog. I.D. 47633 Steel Lake Crest Preliminary Plat Page 6 a total of 8,223 sq.ft., leaving 36,013.5 sq. ft. remaining. The applicant proposes to pay a "fee in lieu of for the remainder of the required open space, for a total of $50,155.12. The proposal was circulated to and approved by the Director of the City Parks Department. The fee will be required to be paid at final plat stage, based on the current assessed value of the land at that time. E. Subdivision Access and Roadway System — The plat will be accessed by a single access point off of 286' Avenue South and the lots will be accessed by an internal loop road. The applicant is being asked to dedicate an additional 9 feet of right-of-way along the east side of 28'b Avenue South and construct half -street frontage improvements. F. Pedestrian System —The internal loop road in the plat will include curb, gutter, and sidewalks for pedestrian access throughout the plat. In addition, an 8-foot-wide paved pedestrian pathway will be constructed from the internal road in the northeast area of the plat that will follow the outside edge of the proposed storm drainage area and connect to Military Road South. The half - street frontage improvements will allow safer pedestrian travel along 28'b Avenue South as there are no sidewalks along this area at this time; only a narrow paved area outside of a white line marked along the roadway, which is used by students travelling along the road to either a bus stop or path to their schools. G. Landscaping — The applicant's preliminary landscape plan provides landscaping as required by FWCC Chapter 20, "Subdivisions," and FWCC Section 20-186, "Landscaping protection and enhancement", including street trees along public roads and internal landscaped open space and common areas. As a recommended condition of preliminary plat approval, the applicant's final landscape plan shall be prepared in accordance with the preliminary plat conditions of approval and shall be submitted for the City's review and approval prior to issuance of engineering approval for plat improvements. FWCC Chapter 20 requires perimeter landscape buffers only when the plat abuts an incompatible zoning district. The proposed plat is bordered on two sides by single-family residential zoning; therefore, no buffers are required along the north and south boundaries of the plat. The applicant is required, however, to provide landscape buffers along an arterial street. Ten -foot landscaping buffers are provided in Tracts B & C along 28`h Avenue South and a ten - foot landscaping buffer is provided along the side of Military Road South, adjacent to the exit of the pedestrian pathway. In total, 4,451 sq. ft. of landscaping will be provided in three separate tracts. Street trees and other vegetation will contribute to visual buffering along these areas. The applicant's Tree Retention Plan prepared by the Roper Company and dated May 30, 2008, indicates the location of existing significant trees, identification of trees to be preserved, and the location of replacement trees. The plan also identifies the remainder of other trees located on the property, most of which will be removed with mass grading of the site. The FWCC requires that 25% of the significant trees remain on site or be replaced with additional evergreen trees. Of the 87 significant trees, the applicant will remove 68 of them, leaving 19 trees, or 22%. In order to meet minimum requirements of the code, the preliminary landscape plan identifies that the applicant proposes to add eleven evergreen replacement trees, placed sporadically on some of the lots within the plat. H. Clearing, Grading — Pursuant to FWCC Section 22-179, all natural vegetation shall be retained on the site to be subdivided, except that which will be removed for infrastructure improvements or grading as shown on approved engineering plans. Existing mature vegetation shall be retained to the maximum extent possible. The effect of these provisions is that mass clearing and grading Staff Evaluation File 07-103897-00-SU/m., J.D. 47633 Steel Lake Crest Preliminary Plat Page 7 is not permitted. Only areas where infrastructure is required may be cleared prior to final plat approval. Additionally, 20-179(c) states that "lots created on slopes of 15% or greater shall minimize grading and shall not result in extensive use of retaining walls. Slopes are to be measured in their natural state." The applicant proposes to do mass grading on the site, resulting in the clearing, grading, and removal of a majority of the significant trees and other vegetation on site. There are over 200 trees on the site, but not all of them are considered "significant trees." A Landscape Plan (L-1) and Tree Retention Plan (L-2) were submitted by the Roper Company, last revised submittal was submitted on August 4, 2008, but the plan was dated May 13, 2008. The plan and retention report identified that there are eighty seven (87) significant trees located on the subject site? Pursuant to the provisions of FWCC Section 22-1568, removal of more than 75 percent of the significant trees requires replacement in the amount of 25 percent of the existing significant trees. The applicant proposes to retain nineteen (19) of the significant trees and provide tree replacement through installation of eleven additional replacement trees at the time of planting on some of the lots within the preliminary plat site. The proposal will just meet the minimum required percentage of tree preservation and replacement, but the mass grading project will remove most of the internal trees and a majority of the trees on the east side of the parcel. The proposed subdivision is not consistent with the provisions of FWCC 20-179 (a), (b), or (c). The applicant proposes to mass clear and grade the site. The preliminary grading plan shows significant cutting and filling in areas exceeding 15% slope. Retaining walls are not depicted, I ut based on the proposed plat grading plan, it is highly likely that extensive retaining walls would be proposed with home construction. VII. TRANSPORTATION A. Street Improvements —As proposed and as required by the FWCC, any required right-of-way dedication must be established through Statutory Warranty Deed to the City of Federal Way and all internal and external streets must be improved to meet all applicable FWCC street standards. The section for 28`h Avenue South is a section `K' and includes a 78-foot-wide right-of-way, 44- foot pavement width, vertical curb and gutter, six-foot planter strips, eight -foot -wide sidewalks, streetlights, and street trees. Submitted plans demonstrate how the full street section can be constructed with an additional nine -foot ROW dedication. The approved internal roadway is a Type `W' street and includes 28-foot pavement width, vertical curb and gutter, four -foot planter strips, five -foot -wide sidewalks, three-foot utility strip, streetlights, and street trees. A sight distance analysis was provided and reviewed by the City. An 8-foot-wide paved pedestrian pathway will be constructed from the internal road in the northeast area of the plat that will follow the outside edge of the proposed storm drainage area and connect to Military Road. The half -street frontage improvements will allow safer pedestrian travel along 28`h Avenue South as there are no sidewalks along this area at this time; only a z A significant tree is defined in the FWCC as a tree that is in good health, not detrimental to the community, and at least 12 inches in diameter 4.5 feet above the ground, not including red alder, cottonwood, poplar, or big -leaf maple.

The City's Traffic Engineer reviewed the submitted plans and concluded that the proposed street layout of the Steel Lake Crest project is consistent with the adopted codes and comprehensive plan. B. Concurrency — Per FWCC Chapter 19, Article IV, a concurrency permit is required for the development. At the applicant's request, a concurrency analysis was performed by the City to determine whether there is adequate roadway capacity to accommodate the development and identifies traffic mitigation consistent with RCW 82.02. The staff report of the Concurrency analysis identified 9 Transportation Improvement Plan (TIP) projects impacted by one or more PM peak hour trips resulting in $39,790.00 in pro-rata mitigation necessary to address any failures of the City's Level of Service (LOS) standard. The table below lists current TIP projects impacted by the proposed development and the appropriate pro-rata contribution. Prior to final plat approval, the applicant shall pay the project pro-rata share contribution in the amount of $39,790.00 to the City.

PUBLIC SERVICES A. Schools — As part of the City's review of the proposal, the preliminary plat application and a School Access Analysis was prepared by Schweikl & Associates, dated May 8, 2007 and was submitted to the Federal Way School District for review_ According to District comments the Staff Evaluation File 07-103897-00-SU/D. I n- 47633 Steel Lake Crest Preliminary Plat Page 9 proposed development will generate approximately 20 to 21 additional school aged children. The site is located in the service areas for Wildwood Elementary, Sacajawea Middle School, and Federal Way High School. The elementary and middle school students would he required to walk to bus stops along 28`h Avenue South, located at 310`h Street and 311" Street, respectively. The Federal Way High School students would be required to walk to school from this development. School service areas are reviewed annually and may be adjusted to accommodate enrollment growth and new development. School impact fees, as authorized by City ordinance and collected at the time of building permit issuance, are currently $3,883.00 (plus a $194.00 City administrative fee) per single-family housing unit. School impact fees are determined on the basis of the District's Capital Facilities Plan and are subject to annual adjustment and update. B. Parks & Open Space — The applicant is proposing to install a pedestrian pathway and three landscaping buffer areas, for a total of 8,223 sq.ft., leaving 36,013.5 sq. ft. remaining. The applicant proposes to pay a "fee in lieu of for the remainder of the required open space, for a total of $50,155.12. The proposal was circulated to and approved by the Director of the City Parks Department. The fee will be required to be paid at final plat stage, based on the current assessed value of the land at that time. C. Fire Protection — South King Fire and Rescue requires that a hydrant be located on the east end of the plat. Fire hydrants must be spaced 600 ft. or less apart. Every building lot shall have a fire hydrant within 300 ft. and all measurements must be made as vehicular travel distance. All hydrants shall be in service prior to and during construction. A Certificate of Water Availability from Lakehaven Utility District indicates that water will be available to the site in sufficient quantity to satisfy fire flow standards for the proposed development. IX. UTILITIES A. Sewage Disposal — The applicant proposes to serve the proposed plat by a public sewer system managed by Lakehaven Utility District. A May 2007 Certificate of Sewer Availability indicates the district's capacity to serve the proposed development through a Developer Extension Agreement (DEA) between the applicant and the district. However, the applicant has since had to reapply for the availability letter since the determination is only valid for one year from date of issuance. The applicant still needs to apply for the DEA. B. Water Supply — The applicant proposes to serve the subdivision with a public water supply and distribution system managed by the Lakehaven Utility District. A May 18, 2007, Certificate of Water Availability indicates Lakehaven's capacity to serve the proposed development through a Developer Extension Agreement (DEA). Again, the applicant was required to re -apply for the availability letter in 2008. The DEA is still required. C. Drainage Facilities — Development of the site will create additional runoff from new impervious surfaces such as streets, driveways, and rooftops. Storm drainage facilities are being designed in accordance with the requirements of Level 1 Flow Control and Basic Water Quality treatment of the 1998 KCSWDM, as modified by the City. The applicant's storm drainage Preliminary Technical Information Report (TIR), dated July 2007, revised May 2008, includes the Level I Drainage Analysis, which was reviewed by the City's Public Works Department. According to the TIR, stormwater runoff currently discharges towards the northeast comer of the site, and Staff Evaluation File 07-103897-00-SU/D.�. rD_ 47633 Steel Lake Crest Preliminary Plat Page 10 enters a roadside ditch along the western edge of Military Road South, which then flows to the south, is then conveyed through a series of pipes under Military Road and Interstate 5, and eventually drains into Lake Dollof, which lies at the upper reaches of the Mill Creek drainage basin. Mill Creek eventually flows into the Green River, which eventually flows into Puget Sound. Preliminary design of the plat roadway and drainage systems indicates that stormwater runoff from the site will continue to discharge at the current, natural location. Additionally, a narrow strip of 28'h Avenue South, along the western edge of the project site, drains to the north and west into Steel Lake. Street improvements within 28 h Avenue will increase the amount of impervious area that drains to Steel Lake. The increase in impervious area does not warrant additional flow control or water quality treatment facilities; however, the developer's engineer has agreed to install a small water quality treatment facility in the lowest downstream catch basin, if, during final engineering design that it is determined to be necessary. Stormwater design and plat drainage elements must conform to the standards, policies, and practices of the City of Federal Way's Public Works Development standards, and the City of Federal Way's Surface Water Management Division as outlined in the 1998 KCSWDM, the Comprehensive Surface Water Management Plan, and the Stormwater System Operation and Maintenance Manual. The approved storm drainage facilities must be constructed per City code requirements prior to final plat approval and recording of the subdivision. X. ANALYSIS OF PRELIMINARY PLAT DECISIONAL CRITERIA The FWCC establishes review procedures and decisional criteria for deciding upon various types of land use applications. Pursuant to FWCC Chapter 22, "Hearing Examiner's Decision," Section 22- 445; and pursuant to FWCC Chapter 20, "Subdivisions," Section 20-110; preliminary plat applications are submitted to the Hearing Examiner for public hearing. The preliminary plat application and the recommendation of the Hearing Examiner are submitted to the City Council for approval or disapproval. Hearing Examiner Preliminary Plat Decisional Criteria — Pursuant to FWCC Section 20-126(c), the Hearing Examiner may recommend approval of the proposed preliminary plat only if the following decisional criteria are met. Decisional criteria and staff responses are provided below. 1. The project is consistent with the comprehensive plan. Staff Comment: The application is subject to the adopted Federal Way Comprehensive Plan (FWCP), which designates the property as Single -Family — High -Density. The proposed land use of a Single -Family housing development is permitted is consistent with density allowances and policies applicable to this land use as established in the FWCP. However, the application is NOT consistent with Chapter 9.3 of the Comprehensive Plan, "Geologic Hazardous Areas. " Goal NEG9 states: `Adopt standards to ensure against the loss of both public and private property in geologically hazardous areas. " In Policy NEP55 of that Chapter, it further states: "as slopes increase, development intensity, site coverage, and vegetation removal should decrease and thereby minimize drainage problems, soil erosion, siltation, and landslides. Slopes of 40 percent or more should be retained in a natural state, free of structures and other land surface modifications. " The proposed design of this plat does not adhere to either the goal or policy of that chapter of the comprehensive plan. 2. The project is consistent with all applicable provisions of the chapter, including those adopted by reference from, the comprehensive plan. Staff Evaluation Steel Lake Crest Preliminary Plat File 07-103897-00-SU/Doc I.D. 47633 Page ] ] Staff Comment: The preliminary plat application is required to comply with the provisions of the FWCC Chapter 18, "Environmental Policy"; Chapter 20, "Subdivisions"; Chapter 22, "Zoning"; and all other applicable codes and regulations. As proposed, to mass grade the site and create lots that require extensive grading on slopes exceeding 15% does not comply with the provisions of Chapter 20, "Subdivisions", Section 20-179, "Retention of Vegetation." The applicant has identified that some areas have slopes up to 40%, some of which were created during grading for the existing homes. The grading and clearing plan shows significant cuts and fills but does not disclose where retaining walls would be placed to create buildable lots for the homes. For these reasons, the proposed subdivision does not meet the criteria of the codes listed. 3. The project is consistent with the public health, safety, and welfare. Staff Comment: The proposed Cottage housing preliminary plat would permit development of the site consistent with the current Single -Family High -Density land use classification of the FWCP and map. Proposed access and fire hydrant locations must meet all requirements of South King Fire and Rescue, and all future structures are required to be sprinklered. Future development of the plat in accordance with applicable codes and regulations will ensure protection of the public health, safety, and welfare. 4. It is consistent with the design criteria listed in FWCC Section 20-2. Staff Comment: The proposed preliminary plat would promote the purposes identified in FWCC Section 20-2 and the standards and regulations therein, as identified in the staff report, including effective use of land, promotion of safe and convenient travel on streets, provision for the housing needs of the community, protection of environmentally sensitive areas, and preservation of a portion of the site as common open space. As proposed, and with conditions as recommended by City staff, the preliminary plat application complies with all provisions of the chapter. 5. It is consistent with the development standards listed in FWCC Sections 20-151 through 157, and 20-158 through 187. Staff Comment: As proposed, the preliminary plat application does not comply with all applicable statutes, codes, and regulations. The proposed mass grading of the site will allow: Extensive grading on slopes over 15%; Clear and grade outside of proposed infrastructure improvement areas; Is not consistent with the requirements of Section 20-179 of the Code. Planning and Public Works staff have met with the applicant to discuss these issues. Public Works staff offered suggestions on how to revise the layout and design of the plat in order to minimize the grading needed. Some of the suggestions were to: cluster development of houses in areas without steep slopes; eliminate some of the lots with the steepest slopes within the interior of the loop road and use that area for development of the required open space area; increase lot sizes; adjust road grades; or do as the code requires, to only grade the individual lots at building pen -nit stage. The applicant has chosen to proceed without implementing any of these ideas. Staff Evaluation File 07-103897-00-SU/Doc 1.D. 47e33 Steel Lake Crest Preliminary Plat Page 12 XI. FINDINGS OF FACT Based on an analysis of the preliminary plat application, environmental record, and related decisional criteria, the Department of Community Development Services finds that: The proposal is to subdivide 6.77 acres into a 28-lot single-family residential housing development project. 2. The proposed single-family residential subdivision is consistent with existing Federal Way zoning and comprehensive plan designations for the RS-7.2/Single-Family High -Density zoning district. City staff received and responded to written comments received from neighbors regarding potential impacts on the neighborhood from increased traffic and removal of significant trees. The comments were considered in the environmental determination on the project. 4. A Mitigated Environmental Determination of Nonsignificance (MDNS) was issued for this proposed action on October 4, 2008, based on the 5taffEvaluation of Environmental Checklist. One comment letter was received regarding the proposed development. No appeals of the environmental determination were filed with the City. The preliminary plat was reviewed and determined to be consistent with most of the subdivision decisional criteria set forth in FWCC Section 20, including consistency with the comprehensive plan; consistency with the public health, safety, and welfare; and, consistency with the design criteria listed in FWCC Section 20-151-157; and many of the criteria in FWCC 20-176-185. However, because of the proposed grading of the site, it is not consistent with FWCC Section 20-179. 6. Lot sizes for the 28 housing parcels range from 7,203 square feet to 8,995 square feet, with an average lot size of 7,391-square feet. This does not include areas set aside as landscaping tracts, dedicated rights -of -way, storm drainage facilities, open space, and the pedestrian pathway. 7. The applicant's proposed grading plan clears the majority of the site, including 78% of the 87 existing significant trees, in conjunction with installation of stormwater facilities and roadway and utility construction. Fifty-four significant trees are located on individual lots that would normally be preserved until building permit review stage. City staff does not support the proposed mass clearing and grading of the site due to the fact that a majority of the existing vegetation will be removed, slopes will be extensively regraded, and proposed houses in the center and north side of the proposed plat will likely require significant retaining walls to maintain slope stability. These aspects of the proposed plat are not consistent with FWCC 20- 179. If however, the Council approves the proposal as submitted, the plat will be subject to review of a final grading plan and subject to all conditions of preliminary plat approval. A TESC will be required as part of the engineering plan submittal to eliminate erosion and aesthetic issues. 8. The applicant's significant tree inventory indicates that nineteen (19) significant trees will be retained within the proposed grading limits. The 19 plus 11 more evergreen replacement trees are proposed to be installed sporadically on some of the lots within the plat. Landscaping will be provided along main roads and in conjunction with development of common open space areas. The development proposes to install more vegetation in some common open space in the planting strip along the internal loop road. The privately maintained open space includes a Staff Evaluation Steel Lake Crest Preliminary Plat File 07-103897-00-SU/Doc. I.D. 47633 Page 13 landscaped pedestrian corridor, and landscaping buffers along 28'b Avenue South and Military Road South. The proposed housing development is subject to review of final landscape plans as a condition of preliminary plat approval. 10. The applicant submitted a concurrency application that was processed by the City's Traffic Engineer. The report found that the proposed development will impact 9 of the City's Transportation Improvement Plan (TIP) projects with one or more PM peak hour trips, and as a result, $39,790.00 in pro-rata mitigation must be paid to address any failures of the City's Level of Service (LOS) standard prior to final plat approval. City staff concurs with this mitigation as -a recommended condition of preliminary plat approval. 11. Vehicular access into the housing development will be available off of 28`h Avenue South. Plat layout provides for good vehicle and pedestrian circulation in accordance with all applicable right-of-way improvement requirements. In accordance with the FWCC, all street improvements along 28`b Avenue South must be dedicated and improved to current street standards, while landscaping improvements along Military Road South adjacent to the paved pedestrian pathway. The internal driveway width of 28 feet is satisfactory for the housing development. The City's Traffic Engineer has reviewed the project and concluded that the proposed street layout is consistent with the adopted codes and comprehensive plan in place at the time of the complete application. 12. Prior to final plat approval, traffic mitigation in the amount of $39,790 shall be paid to the City. 13. The applicant provided a school access analysis that indicates that the site will generate between 20 to 21 new school students that will be served by Federal Way High School, Wildwood Elementary School, and Sacajawea Middle School. High school students from the plat will be required to walk to school. Elementary and middle school students will be bused from existing nearby stops, or new and additional stops as the district may determine appropriate for the conditions. School impact fees will be assessed and paid to the School District with individual building permits. 14. Design and construction of surface drainage facilities in accordance with the 1998 KCSWDM and recommended conditions of preliminary plat approval, will ensure that all potential erosion, surface water runoff, water quality, and infiltration/storage-related impacts are addressed. The applicant's TIR was reviewed and accepted by the City's Public Works Department subject to final engineering review. Storm drainage facilities generally consist of infiltration trenches, pervious pavement, and a storm drainage pond. 15. The preliminary plat application was reviewed for consistency with all applicable state and local codes, policies and regulations, including the Federal Way Comprehensive Plan (FWCP); Federal Way City Code (FWCC) Chapters 18, "Environmental Policy"; 19, "Planning and Development"; 20, "Subdivisions"; 21, "Surface and Stormwater Management"; Chapter 22, Article IV "Improvements"; Article XVII "Landscaping,"; the 1998 King County Surface Water Design Manual; and Federal Way Development Standards. As proposed and recommended by staff, the preliminary plat is NOT consistent all elements of the Comprehensive Plan, specifically, Chapter 9.3, `Geological Hazardous Areas", Goal NEG9, and Policy NEP55 as outlined above; and, the proposed plat in NOT consistent with the FWCC, specifically Section 20-179. Staff Evaluation File 07-103897-00-SU/Doc L.D 47633 Steel Lake Crest Preliminary Plat Page 14 16. Water and sewer facilities are available from Lakehaven Utility District and are adequate to serve the proposed development. It is the applicant's responsibility to secure all necessary water and sewer services from the utility provider. XII. RECOMMENDATION Based on review of the applications, environmental record, and pertinent decisional criteria, the Department of Community Development Services recommends that the Hearing Examiner recommend DENIAL of the preliminary plat. If, however, the Examiner chooses to recommend approval, City staff recommends the following conditions be attached to such approval: 1. Prior to the City's approval of engineering plans, the applicant shall provide a detailed design for clearing and grading for the entire site. The applicant -may be required to provide additional bonding or maintenance provisions for methods not currently approved by the 1998 KCSWDM. 2. Final plat approval shall require full compliance with drainage provisions set forth in the FWCC. Compliance may result in reducing the number and/or location of lots as shown on the preliminary approved plat. Final storm drainage engineering plans shall comply with the following: a. Drainage plans and analysis shall comply with the 1998 KCSWDM and amendments adopted by the City of Federal Way. City of Federal Way approval of the drainage and roadway plans is required prior to any construction. b. The combined detention and water quality facility shall be designed to the Level 1 Flow Control and basic water quality treatment criteria of the 1998 KCSWDM, as amended by the City of Federal Way. Final review of the stormwater quality and detention facility will occur in conjunction with plat engineering review. 3. Prior to the City's approval of engineering plans, the applicant shall strive to reduce the quantity and overall height of any proposed retaining walls or rockeries. Approved retaining walls or rockeries associated with plat construction shall reflect residential housing, scale, design, and sensitivity of materials or treatment, including use of texture, vegetation, and terracing. If there are retaining walls added to the preliminary plat drawings that were not shown on the original drawings presented to the City Council for approval, the applicant shall be required to submit the revised drawings to the Community Development Department for a modified plat approval process through the Council. 4. Prior to final plat approval, the final plat drawing shall dedicate all common open space in open space tract(s) to be owned in common and maintained by property owners of the proposed subdivision, and shall prohibit removal or disturbance of vegetation and landscaping within the tract, except as necessary for maintenance or replacement of existing plantings and as approved by the City. A note shall be included on the final plat map that the open space tract shall not be further subdivided, may not be developed with any buildings or other structures except as may be approved by the City for recreational purposes only for the benefit of the homeowners, and may not be used for financial gain.

If the mass clearing and grading of the plat is approved, and the applicant proceeds to clear and grade the site, the applicant shall: a. Stabilize the site in accordance with Best Management Practices; and, b. Provide a written commitment to make every effort to commence house construction within two months of Final Plat approval; and, c. Provide an estimate of the gross value of harvestable timber on the site. If home construction is not started within 2 months of final plat approval, a fee equal to the amount of the gross timber value shall be paid to the City by the owner of the plat. X1II.

I have attempted to understand and respond to all of your questions. If I have missed anything, please let me know. I have not responded to some of your statements, which are opinion -based and do not lend themselves to fact -based responses. Option 1 The Hearing Examiner (Examiner) will issue a recommendation to City Council (Council). This recommendation will be forwarded to the Land Use/Transportation Committee (LUTC) for consideration. LUTC, at a public meeting, will make a recommendation to the full Council. Council, at a public meeting, will make a decision either approving or denying the preliminary plat. The applicant may choose to withdraw the application at any time during this process. Council's decision can be appealed to superior court within 21 days of issuance. We have no way of determining the time it would take to go through the appeal process in superior court. Consult your legal counsel for advice on this topic. Barring appeal, if the application is denied by Council it is dead and a new application must be submitted. The new application must meet code requirements in effect at the time the application is submitted. The application will be vested to code requirements in effect at the time a fully complete preliminary plat application is submitted to the city. As you noted, much of your previous work would likely still be valid and could be re -submitted (with minor revisions in some cases to reflect changes to plat design as necessary). The previously issued SEPA decision, for example, may still be valid, depending on the extent of changes made to the design. As such we may handle that issue by simply adopting it by reference for the new application. As you noted, certain technical documents would need to be revised. There was no time period associated with the shoreline exemption approval. The exemption will continue to be valid provided the application is resubmitted within a reasonable period of time and the work within the shoreline jurisdiction is roughly equivalent to what is now proposed. Note that the exemption was approved partly because the grading work on lot #1 was valued at less than $5,000 (pursuant to WAC 173-27-040[2][a]). When you resubmit, you will need to identify the current cost of this work and we will need to verify that it is less than the current valuation limit for exemption (the exemption amount is adjusted upward for inflation periodically). File k07-103897-00-SU Doc 1. D 47875 ^ -- Mr. �Bra4t Sch,4eikl Page 2 November 24, 2008 Right-of-way modification requests expire one year from approval. You may request an extension of one year. Current fees at time of application will be required. The current 2008 fee for a preliminary plat application is $7,334.50 plus 75.50 per acre. Depending on the extent of changes to plat design, as noted above, the SEPA fee of $903.50 may not be required. These fees are fixed and can not be adjusted for perceived efficiency due to resubmittal of already reviewed materials. Fees will increase slightly on January 1, 2009. It is difficult to guess the date the clear and grade code revisions will go into effect. It will not get out of Planning Commission until late January at the earliest. From there I would not want to speculate on how long it will take going through LUTC and Council. City code identifies processing timelines (28-day completeness review, 120-day technical review) that I expect staff to meet. Given that much of the information has been previously reviewed, I expect we should be able to complete our review of the preliminary plat application faster second time around. Option 2 If the preliminary plat is approved I think it is unlikely the city would appeal the decision. Remember, the Examiner only issues a recommendation —this is not appealable. Council issues the decision. It would be highly unusual for the city to appeal its own decision. We are glad to meet with you again to discuss options to meet Federal Way City Code (FWCC) 20-179, provided the design team is open to making changes. There is only limited benefit in meeting unless it is in a collaborative spirit. The language in FWCC 20-179 is primarily an attempt to address aesthetic issues surrounding subdivision development. The limitation on mass clear and grade operations is intended to maintain a more visually appealing environment during the period of infrastructure construction and into home construction, and potentially result in the retention of more mature vegetation. The limitation on grading and retaining walls on slopes exceeding 15% is, again, primarily intended to address aesthetics. Recent developments on steeper sloped sites have resulted in extensive grading and large retaining walls visible from the public right-of-way and adjacent residential property. You stated you have a concern about the Examiner's response to your statement that you were doing this work, "on your own nickel." He responded by saying, "I am aware of that." Staff did not discuss this issue with the Examiner. I expect he misunderstood your meaning and took it to be a general statement about the cost or how you provide your services. I hope this letter addresses your questions adequately. Please contact me if you need further clarification. I can be reached at (253) 835-2611.

Project: Steel Lake Crest: 07-103897-00-SU, SA Project No.: 06066 RE: Clarification of Site Grading This letter has been prepared in response to a request for farther explanation on the grading plan for the Steel Lake Project. The project proposes mass grading of the site. There are several factors why this course of action is being proposed for this project. Do to the topography of the site, the proposed roadways will govern most of the sites grading. Meeting city street slope requirements precludes the use of cutting and filling to construct the proposed roadway. If the roadway and utilities were to be installed without allowing grading to any other portions of the site ( the direct result of strict adhesion to FWCC 20-179) the intent of the code could actually work against itself. Driveways to the individual lots would most likely have to be built on cuts or fills to meet the roadway elevations, causing each individual building permit (builder) to come up with their own plan. The code calls for minimizing grading and/or retaining walls on lots. This would likely cause just the opposite to happen. Without mass grading of the site the newly constructed improvements would act as barriers to the storm water system and actually create ponding in unwanted areas of the site. Overall erosion control measures would be harder to install and maintain. When the lots were allowed to develop (build on individual lots) the additional grading/construction that would take place at that time has the potential to cause more damage at the site (a combination to the installed improvements and to the existing vegetation) than an initial mass grading would have. The proposed mass grade site does preserve significant trees on a lot by lot basis (per FWCC 22-1568) and in fact provides more replacement trees than called for (see the tree retention and landscape plans). Overall the site benefits more when treated as a mass graded site than falling under individual landscape plans at the time of building permits. This also holds true for erosion control and site grading. As a mass graded site, the site is LT FW Mass Grade.doc a balanced site with no need to move material onto or off the site.

Specifically, this will address comments made in the July 16, 2008 comment letter. Planning Division, Joanne Long -Woods Landscape Plan 1. The plan represents the plant and tree material for the entire site and I believe that the title for the landscape tract detail for Tract D was mistaken for the title for the title the project plant material list. With the sense of this being a conceptual landscape plan we did not prepare a plant and tree material list for each individual parcel since all the plants and trees for the project are shown and the final landscape plan could provide is amount of detail for the final approved engineering plans if it is required at that point in time. 2. Revised 3. The existing Sheet L1.1 did have the pedestrian path label in one view and we have added the tract name to the other view also. 4. We have verified that the type of street trees proposed is in compliance with the FWCC for the classification of roadway. Site Plan 1. Added notes to ownership/maintenance of the tracts.

The vegetation of Sheet PP-1 was removed since it was developed only for the purposes of providing a sketch of the proposed reduce pedestrian path for discussions with City Staff. The Conceptual landscape plan will contain all of the pertinent landscape information and not Sheet PP-1. 3. The length of the path was added. Public Works Department, Kevin Peterson 1. Added the City File number. 2. Provided two pond cross sections, Section B and C on new Sheet PP-2. 3. The cell wall had been frozen and it not properly appears. 4. Added proposed radii for each curb return. 5. Added proposed radii at each intersecting right-of-way line. 6. Indicated tract dedication and ownership. 7. Added top and bottom of wall elevations. Per an e-mail communication with Kevin we were allowed to have a pond wall of nine feet in height. 8. Noted that the project will require a stormwater discharge permit from WSDOT prior to engineering plan approval. Lakehaven Utility District, Brian Asbury We contacted Brian and he indicated that he did not require any further submittal for the project to gain preliminary plat approval.

Specifically, the request addresses the following: 1. Reduction in the width of the pedestrian pathway and associated tract, located between Lot 28 and storm drainage pond Tract "A'. Current City standards require the pedestrian pathway be paved to a width of 12-feet, located within a 20-feet wide tract. After evaluating the existing conditions along the referenced streets, review of Federal Way City Code (FWCC) provisions, and direction provided by the City Council, the Public Works Department hereby approves your request to modify the width of the pedestrian connection, as follows: The reduced width maintains the purpose, function, and safety of the required pedestrian connection between the plat and Military Road. The pedestrian connection shall be constructed to the following standards: Eight (8) feet wide, three (3) inch thick (compacted depth) asphalt concrete pavement over four (4) inches of compacted depth crushed surfacing top course, centered within a fourteen (14) foot wide tract, and planted on each side with low -growing shrubs and landscaping. Pedestrian -scale lighting shall be provided along the pathway. Sight - obscuring fencing and/or landscaping will not be permitted along the corridor.

We have reviewed our original Right-of-way Modification Response per your request, and are unable to grant any further modifications for the following reasons: As indicated before, per FWCC 20-157, the connection is required. Staff does not believe that this requirement can be modified or waved based on the modification criteria contained in either FWCC 20-157(c) or FWCC 22-1477. • City of Federal Way Comprehensive Plan policies encourage the use of non -motorized trips including and not limited to the following: o TP29: Reduce reliance on the single occupant auto by prioritizing and implementing supportive local -level transit, HOV, and non -motorized improvements. o TP 30. Identify and plan for multi -modal freeway, arterial, and collector street improvements which ensure more efficient use of existing roads and enhancement of HOV, transit, and related non -motorized operations. o TP52: Work to extend the existing system of sidewalks, bikeways, and equestrian ways in the City to provide safe access to public transit, neighborhood and business centers, parks, schools, public facilities, and other recreational attractions. • The City has granted the project modifications that (eliminate the vehicular access to the east and eliminate the second access point to resolve sight distance issues), therefore the need for this pedestrian connection becomes more crucial. From a safety point of view, this connection could be used as an emergency access should 28th Avenue South become blocked due to a natural disaster or any other reason. L:\CSDC\DOCS\SAVE\6 536278098.

The project is located east of 28th Ave S and north of S 308'h ST. Under current boundaries Wildwood Elementary, Sacajawea Middle School and Federal Way High School service areas. School service areas are reviewed each year and necessary boundary changes may be made to accommodate enrollment increases. Students living in this area receive school bus transportation to Wildwood Elementary and Sacajawea Middle School. Under current boundaries students would walk to Federal Way High. Bus stops are reviewed annually as student transportation needs change. The closest stop for Wildwood Elementary is on 28th Ave S at S 310t' ST. The closest stop for Sacajawea Middle School is on 28"' Ave S at S 311" ST. Student safety must be considered for all students who would walk to the schools and to school bus stops from this development. Sidewalks and other planning features that assure safe walking conditions for students are factors the district must consider as we comment on development within our service areas. We ask the developer to prepare a "School Access Analysis" to the elementary, middle school and high school from this proposed development. Attached are guidelines for preparing this analysis. The most recent Federal Way School District Capital Facilities Plan indicates a student yield of .7060 from new single-family housing. This development could add 20 to 21 new students. These are averages only; the actual number of students may vary. This may create a need for additional space, equipment and staff. This impact is mitigated by the collection of impact fees. The District appreciates the opportunity to comment on this proposed development.

No information was submitted with the application to support the mass grading depicted on the plans. If mass grading is indeed proposed, additional information is required to support the request, including but not limited to identification of unusual conditions that warrant mass grading; identification on the preliminary plat of those lots created on slopes of 15% or greater; the locations of proposed rockeries, retaining walls, and terracing; and the proposed locations for dwelling units as well as identification of the housing type (such as split level houses) for those internally graded lots. The grading and clearing plan should match the revised preliminary plat layout. 2. Open Space — As noted in the preapplication summary letter, open space in the amount of 15% of the gross land area is required to be provided with a formal subdivision, or the applicant can propose to make a fee -in -lieu -of payment at the time of final plat review per FWCC Section 20-156. In the case of the 6.72 acre (292,862 square foot) subject site, the 15% open space obligation would be 43,934 square feet. The three proposed landscape buffer tracts can be counted towards as buffer open space. Please provide the square footage of these tracts to be deducted from the overall open space obligation and clarify that the balance of the open space obligation will be via fee -in -lieu -of payment_ 3. Landscape plan - Landscape plans prepared by The Roper Company have been reviewed. They depict existing vegetation to be removed as well as proposed landscape improvements. Prior to preliminary plat approval, the landscape plan must be revised to reflect the new plat layout. Prior to engineering approval, the street trees depicted on the plan must be revised to meet the requirements of the enclosed street tree handout. Trees on 28"' Avenue South must correspond to Type `K' street tree requirements, while trees on the internal plat roadway must comply with type ' W' tree requirements. In addition, the t Federal Way City Code (FWCC) section 20-179 Retention of Vegetation, notes that all natural vegetation shall be retained on the site except that which will be removed for improvements or approved grading; existing mature vegetation shall be retained to the extent possible; preservation of significant trees shall apply solely to the development of each single family lot at the time a building permit is applied for; lots created on slopes of 15% or greater shall minimize grading and shall not result in extensive use of retaining walls, and slopes are to be measured in their natural state. Doc_ I.D. 42867 Steel Lake Crest Preliminary Plat Mr- Brant Schweikl November.3O, 2007 Page 2 t.. size of the street tree must be reflected as a two-inch caliper per ANSII standards. The landscape plan must be revised to clarify the type of planting materials proposed in Tracts B, C and D; must clarify that the screening trees planted around the pond are in a separate tract to be owned and maintained by the Homeowners association; and must show the location of any screening fencing within Tracts C and D. Refer to the enclosed red -lined landscape plan. 4. Significant trees — The tree retention plan prepared by The Roper Company states that there are 87 significant trees on the property, and that 76 of the significant trees are proposed to be removed. It appears that 33 of the significant trees are to be removed for roadway and infrastructure installation, 43 significant trees would be removed from individual building lots and 1 I significant trees would be retained at the rear of individual building lots. Under FWCC section 20-179(b), the significant trees removed with the infrastructure installation are not subject to replacement requirements but removal of significant trees on individual building lots can occur only following issuance of a building permit. However, if a mass grading proposal is approved for the subdivision, removal of significant trees from building lot areas would be regulated on a lot -by -lot basis. If mass grading is proposed, a tree replacement plan must be submitted for review. It must depict the number of significant trees removed from each lot; the corresponding number of replacement trees required for each lot based on FWCC section 22-1568; and list the size, type and proposed location of each replacement tree. Please note that if approved, replacement trees must be located on individual building lots, or alternatively located on tracts owned and maintained by the Homeowners Association. 5. Noise - An Environmental Noise Review prepared by SSA Acoustics, LLP dated June 1, 2007 was submitted for review. The report notes that exterior noise levels at the site exceed the recommended HUD guidelines and mitigation measures will be necessary. The report lists two recommendations to mitigate noise — providing exterior envelope construction or noise barrier mitigation. It is unclear from the environmental checklist which option is proposed with this project. 6. Driveway standards — The City adopted private driveway standards in May 2007. Driveway access to proposed lots #1 and 2 and 22 and 23 must be revised to reflect the adopted enclosed drawing No. 3- 2CC Private Driveways Serving 2 Lots. Street lights- The location of street lights must be added to the preliminary plat map. Please note that technical comments from the Public Works Engineering and Traffic Departments will be available is a few weeks time. When resubmitting, please provide six copies of any revised plans and four copies of any reports accompanied by the enclosed resubmittl information form.

The survey indicates that adequate sight distance is not available to the south at the north access driveway. The report indicates that approximately 350 feet sight distance is available compared to the required 385 feet for a 35 mph speed zone. The report indicates that providing a two way left turn lane along the frontage of the property would mitigate this deficiency. We do not concur with the above conclusions from the report for the following reasons: 1. Providing a two way left turn lane would not help improve the sight distance for the northbound egress movements. 2. The site plan provided indicates that the entering northbound approach grade at the proposed north access driveway is approximately 9 percent. With this level of steep grade, the sight distance criteria to the south for the northbound left turn and right turn movements would be approximately 475 feet and 426 feet, respectively. As these requirements are not met based on the submitted material, we conclude that it is unsafe to allow any egress movements from the north access driveway. Please provide other mitigation measures so that the sight distance criteria would be met at the north access driveway. Please be advised that additional technical comments from City staff will be provided at a later date. When resubmitting requested information, please provide six copies of any revised plans and four copies of any report accompanied by the enclosed resubmittal information form.

I.D. 42287 RECEIVED BY COMMUNITY DEVELOPMENT DEPARTMENT AUG 2 2 2007 21 August 2007 TO: Director of Community Development Services City of Federal Way SUBJECT: Notice of Land Use Application Steel Lake Crest Preliminary Plat My wife and I own the property directly across 28t` Ave. So. (30615 28 h Ave. So.) that has the longest front footage that faces the proposed plat. We purchased our home 30 years ago when it was approximately 2 years old. At the time, it was sold as an "executive" home with approximately 2500 square feet and a beautiful view of Steel Lake. We were in a rural part of unincorporated King County where our neighbors had farm animals (i.e. horses, chickens, etc.). Traffic on 286'Ave. So. was relatively minor. During the 30 years we have lived here we have sadly watched the road get busier and busier every year to the point where there is a constant stream of traffic that makes it extremely noisy and, at times, almost unsafe to merge into it in order to exit our home. The obvious lack of growth management which, by the way, I remember as being one of the campaign reasons Federal Way should become a city, has, in my opinion, caused much of the congestion that plagues this city. When people ask me where I live I tell them I live in a suburb of Seattle, hoping they won't ask the name of the city because I'm embarrassed to say Federal Way. From my observations there are now 4 homes and lots of trees that will become 29 homes and, if they do what they normally do, no trees. This area, as it now exists, at least has some scenic beauty and is a noise buffer to Interstate 5. In the "Description" you state "The project includes street improvements, construction of storm drainage facilities, and utility improvements". What kind of "street improvements" do you mean? Do you plan to make 28t` Ave. So. a 4 lane road by widening it so that it will be touching the edge of my garage? There is no logical way you can "improve" 28 h Ave. So. other than to reduce the volume of vehicle traffic using it. Do you plan to put a stop light on 28`h Ave. So. so these new home owners can enter and exit their property without getting broadsided? If you do that, 28t` Ave. So. traffic will stack up at the stop light which will further congest the road and the rest of us will never be able to enter the road. If the "street improvement" is to repave the road or to maintain the road aren't those things that are already being done? I firmly believe that somebody needs to look at this, not from the standpoint of a developer looking to make a buck, but from the standpoint of the citizens of Federal Way, especially those of us that live in close proximity to it. I To show you how serious I am about this issue, I will retract this letter if somebody will pay me the fair market value for my home. As a matter of fact, I will sell my home immediately and vacate it within 30 days even if it means putting all my possessions in storage. People have told me that I am wasting my time writing this letter since nobody will probably even bother to read it and, if they do, nobody cares or will do anything anyway. They may be right, but I look at it like an election, it's harder to complain about the results if you didn't bother to vote.

David Kaplan at November 18, 2008 City Council Meeting For more than a year, I have been working with Community Development and Public Works Staff on three projects: Revisions to the Clearing, Grading and Tree Code, the Steel Lake Crest development and the Federal Way Regional Library expansion. There have been numerous conversations, a -mails and letters regarding all three. I'm pleased to say that some of my recommendations have been included in preliminary drafts of the projects. Others are still being negotiated. While none of the projects have yet to come to a conclusion, I want to thank all those involved for their courtesy, patience and professionalism. Through it all, I have been impressed by the detailed response and logic of opinions expressed by staff. We are fortunate to have such dedicated employees as Deb Barker, Margaret Clark, Greg Fewins, Joanne Long -Woods, Rick Perez and Janet Shull serving the citizens of Federal Way. Thank you. Joanne Long -Woods From: h.david kaplan [hdk1934@hotmail.com] Sent: Wednesday, November 12, 2008 1:46 PM To: Cary Roe; Joanne Long -Woods; Greg Fewins; Neal Beets; Rick Perez Cc: hdk1934@hotmail.com Subject: Steel Lake Crest I met Rick Perez at the site this morning. We reviewed the location of the driveway, the trees and vegetation that will be cleared back from the road and then counted the seconds elapsed from the time a car came over the crest of the road until it reached the location of the driveway. Rick said a minimum of six seconds is required for adequate sight distance. We counted nearly nine seconds. The unknown, of course, was the speed of the car coming down the road towards us. The speed limit is 35 mph, but people drive faster than that. Even so, I think the nine seconds would be sufficient, even at 40 mph. My one remaining concern is that persons exiting the development will have to look both north and sound before making a left-hand turn heading south on 28th. I just hope there's enough time to make a safe turn. That concern is not part of this preliminary plat. Therefore, I hereby withdraw my objections to the MDNS and will not appear at the November 17 hearing. Thanks to all for their assistance in resolving this matter to my satisfaction. H.

I am writing in response to comments you submitted on this project when the Notice of Application was published in 2007. At that time, staff copied and distributed those comments to the Public Works Dept. and the applicant's engineer for evaluation and response. Your concerns were basically about the increase in traffic on 28'h Avenue South and the potential need to widen the road to four (4) lanes. I would like to make sure that you understand the current status of the proposed plat. This plat configuration has gone through a few design changes over the past year. As you may or may not know, the present right-of-way width on 28`h Avenue South is 60 feet. City Code does not require 28`h Avenue South to be widened to four lanes, as you had suggested. However, the Public Works Dept. has determined that the applicant will be required to dedicate nine additional feet of right-of-way on the east side of 28 h Avenue to provide half -street frontage improvements along the face of the plat. Also, to meet sight distance requirements, the Traffic Division has required that the northerly entrance to the plat be eliminated because there was not adequate site distance at that location and there is now only one entrance into the plat, at the south end of the property. As an adjacent property owner, you should have received both a notice of the Mitigated Determination of Nonsignificance (MDNS) issued for this plat and a notice that the plat has recently been scheduled for a public hearing before the Hearing Examiner at 11:00 AM on November 17, 2008. If you attend the hearing, you will be able to voice your concerns before the Examiner or you are entitled to submit additional written comments to the Examiner as stated in the notice for the public hearing.

I will respond to each statement in turn, as submitted: Findings of Fact You state that the Finding #4 seems to place emphasis on 1-5 ROW and you quote a statement made by an employee of WSDOT about the value of trees in addressing noise requirements. The finding primarily identifies what was in the submittal of the significant tree removal and replacement plan. The last sentence identifies that a majority of the large trees along the east side of the proposed plat will be removed. As for the statement from a WSDOT employee, I was not a party to a private conversation and have no knowledge of the employee or any statements made. No comments were received from WSDOT on this determination. 2. You identify a discrepancy in file numbers. The correct SEPA file number is #07-103898-00-SE. The Subdivision file number is #07-103897- 00-SU. Thank you for pointing that out. It has been corrected in the findings document. SEPA Conditions You stated that you had had a conversation with Deb Barker about what noise mitigation measure would be utilized to mitigate for noise impacts from being adjacent to the 1-5 corridor. You also mentioned talk about a future transportation construction project between WSDOT and the City. I did find a resubmittal letter where you mention that the exterior construction method was the choice of the applicant. I will revise the staff findings to indicate that and include it into the staff report. Mr. Schweikl Nov erriber`5, 2009 Page 2 Staff Evaluation of the Environmental Checklist 1. Comment noted. Will be required with submittal of engineered drawings. 2. Comment noted. The review does not say hazardous materials were found on the site. The buried materials were identified during soil test pit exploration and the consultant stated in his geotechnical report that no further exploration had been requested. 3. No additional comment identified. 4. No additional comment identified. General Comments You ask if the fact that theproject had received an exemption from having to get a Shoreline Permit could be referenced, as a matter of record for the public. The shoreline exemption was acquired before submittal of this application. A copy of the exemption letter will be included with the packet of information to the Hearing Examiner and identified in the staff report.

At that time, I observed that "the proposed center turn lane along the length of the project on 28th Avenue South doesn't solve the sight distance problem". I had no response from anyone, either verbal or written. Therefore, when I returned from a 10/3-10/10 trip out of town, I was surprised to see a MDNS published in the October 4 FEDERAL WAY MIRROR. On October 11, I called city hall and was told Deb Barker was no longer working on this project and that it was transferred to Ms. Long -Woods. I spoke with her and she told me that Deb Barker had written a letter on September 7 to Brant Schweikl in Tacoma and Mr. Schweikl was supposed to respond to my concerns. I said that to date, I had not received any response from Mr. Schweikl. Ms. Long -Woods said she would mail me a copy of Ms. Barker's letter. I did not receive that copy in the mail and obtained one when I was in city hall on October 20. In light of the above, since I have had no response to my original concern from either the City of Federal Way or Mr. Schweikl to date, I feel "aggrieved of the city's final determination" and wish to halt the effective date of the MDNS until my concerns are resolved.

You have stated in recent conversations that you submitted comments on this project when the Notice of Application was published in 2007. At that time, staff copied and distributed those comments to the Public Works Dept. and the applicant's engineer for evaluation. Your concerns were basically about the placement of the access roads and whether there was adequate sight distance at those locations. Based on your comments and internal review of the project, it was determined that the application, as submitted, did not meet minimum code requirements for site distance, and the applicant was asked to revise the design and the sight distance analysis. Your recent comments echo what your original comments were on this case: you are concerned about the location of the proposed access road for this plat off of 280'Avenue South. As you know, the original plat plan showed two accesses off of 28th Avenue South, but as I stated above, internal review of the application identified that there was a site distance problem on the northerly access so it was removed from the plat. I forwarded copies of both of your comment letters to Sanjeev Tandle of the Public Works Department earlier this week. He explains in more detail the specifics of the review of this plat plan and why the design was changed. Below is his response to address your concerns: "The City's traffic division has originally reviewed the Steel Lake Crest preliminary plat application and the sight distance survey report dated July 11, 2007, prepared by Schweikl & Associates, PLLC. The survey indicated that adequate sight distance was available at the proposed southerly access but adequate sight distance was not available at the proposed northerly access. The report indicated that approximately 350 feet sight distance was available compared to the required-385 feet for a 35 mph speed zone. The report also indicated that providing a two-way left turn lane along the frontage of the property would mitigate this deficiency. The staff did not concur with those conclusions from the report for the following reasons: 1. Providing a two-way left turn lane would not help improve the sight distance for the . westbound to northbound egress movements at the north access. MT .Kaplan October 28, 2008 Page 2 2. Based on the approach grade of the proposed north access, the sight distance criteria to the south for the westbound left turn and right turn movements would be approximately 475 feet and 426 feet, respectively. As these requirements were not met based on the submitted materials, we concluded that it is unsafe to allow any egress movements from the north access. The staff required the applicant to provide other mitigation measures so that the sight distance criteria would be met at the north access. Based on the staff comments, the applicant revised the site plan to eliminate the northerly access and reconfigured the plat to include only one site access. The applicant also submitted a revised sight distance analysis report on November 2, 2007. Based on the revised sight distance analysis to reflect the revised plat configuration, the available sight distance at the proposed site access would be 505 feet to the north and 485 feet to the south. The required sight distance is 385 feet for a 35 mph speed zone. Therefore, the staff concluded that adequate sight distance is available at the proposed site access." I hope this additional information helps you understand how the plat design has changed and why. The City does not intend to modify the MDNS issued on this case and it has been scheduled for a public hearing before the Hearing Examiner. The MDNS was final on October 20, 2008, and the appeal period ends 14 days from that date, or November 3, 2008. As a party of record, you will be sent a formal notice of the hearing when scheduled.. You will be able to submit additional comments and/or testimony at the public hearing, if you choose to. If you have any questions, please contact me at 253-835-2640.

We have determined that the proposal will not have a probable significant adverse impact on the environment. As a result, an environmental impact statement (EIS) is not required to comply with the State Environmental Policy Act (SEPA). However, there were some issues we identified that were areas of concern and, therefore, are issuing the environmental determination with mitigation. A copy of the Mitigated Determination of Nonsignificance (MDNS) is enclosed. A 14-day comment period is required by the SEPA Rules (WAC 197-11-340). A notice inviting comments will be published in the Federal Way Mirror on October 4, 2008. At the end of the comment period, October 20, 2008, the department will determine if the MDNS should be withdrawn, modified, or issued as proposed. All final determinations may be appealed within 14 days following the comment deadline. No licenses, permits, or approvals will be issued until completion of the appeal period. Our decision not to require an EIS does not mean that the license, permit, or approval you are seeking from the City has been granted. Approval or denial of the proposal will be made by the appropriate administrative or legislative body vested with that authority. The environmental record is considered by the decision maker(s) and conditions will be imposed to reduce identified environmental impacts, as long as the conditions are based on adopted and designated City policy. File #07-103898-00-SE Doc ID 46898 Ms. Linda Elder Page 2 October 3, 2008 After a final decision has been made on your proposal (i.e., after a permit has been issued or City Council action taken, as applicable), you may, but are not required to, publish a Notice of Action as set forth in RCW 43.21C.075.

Tax Parcels: 0921049182, 0921049183, 0921049096, & 091049161 Lead Agency: City of Federal Way Staff Contact: Senior Planner Joanne Long -Woods, (253) 835-2640 The Responsible Official of the City of Federal Way hereby makes the following decision on this proposed development based upon impacts identified in the environmental checklist; a Subsurface Exploration and Geotechnical Engineering Report, prepared by Jason Engineering & Consulting Business, Inc. June 20, 2007; Technical Information Report, Preliminary Drainage Review for Steel Lake Crest, prepared by Schweikl & Associates, July 2007 and revised May 2008; Environmental Noise Review, prepared by SSA Acoustics, LLP, June 1, 2007; Concurrency Analysis, City of Federal Way, October 2007; Federal Way Comprehensive Plan; Federal Way City Code; and other municipal policies, plans, rules, and regulations designated as a basis for exercise of substantive authority under the State Environmental Policy Act Rules (SEPA) pursuant to the Revised Code of Washington (RCW) 43.31C.060. The lead agency for this proposal has determined that it does not have a probable significant adverse impact on the environment and an environmental impact statement (EIS) is not required under RCW 43.21 C.030(2)(c), if the conditions listed below are met. This decision was made after review of a completed environmental checklist and other information on file with the City. Further information regarding this action is available to the public upon request at the Department of Community Development Services. Preliminary Plat of Steel Lake Crest File #07-103898-00-SE / Doc ID 46899 Mitigated Determination ofNonsignificance (MDNS) Page 1 FINDINGS OF FACT 1. The proposal is to subdivide 6.77 acres into 28 single-family residential lots. The proposal includes construction of a stormwater detention pond; installation of landscaping tracts along Military Road South and along 28 h Avenue South; construction of a paved pedestrian pathway to Military Road South; mass clearing and grading of the site with approximately 17, 000 cubic yards of earth movement; removal of approximately 55 significant trees; and demolition of all existing structures. 2. The four parcels are in an area zoned RS 7.2, requiring a minimum lot size of 7,200 square feet. Parcels in the development range from 7,203 square feet to 8,995 square feet. The comprehensive plan designation in this area is High Density Single Family Residential. The project is located adjacent to the I-5 right-of-way. Seven of the proposed lots, the detention pond, and part of the pedestrian pathway will be located adjacent to the I-5 corridor. In accordance with code requirements, an Environmental Noise Study was conducted by SSA Acoustics, LLP on June 1, 2007. The noise study identified Housing and Urban Development (HUD) standards for noise levels outside and inside of residential housing. Specifically, the Department of Housing and Urban Development Noise Standards consider outdoor Day -Night Average Sound Levels (Ldn) below 65 dBA "acceptable" and the indoor Day -Night Average Sound Level (Ldn) goal is to not exceed 45 dBA. Normal construction can be expected to provide a Noise Level Reduction (NLR) of 20 dB, thus the indoor goal of Ldn less than 45 dBA can be met when the outdoor Ldn is less than 65 dBA. The study identified that the Day -Night Average Noise Level (Ldn) ranged from 67 to 69 dBA. The hourly average noise levels exceeded 56 dBA during the entire four day noise monitor, with a maximum 24 hour Leq of 66 dBA and an average Leq of 62 dBA. The exterior day -night noise levels exceed the recommended HUD guidelines; therefore, mitigation measures will be necessary. 4. Currently, there are 52 trees on the seven lots bordering the I-5 corridor; 30 of these trees are significant trees. Twelve of the 52 trees will be saved and two will be replaced, for a total of 14 trees on the east boundary of the plat. In accordance with code requirements, the applicant submitted a Significant Tree Inventory with a Tree Replacement Plan to address the requirement of maintaining at least 25% of the significant trees on the site. The tree plan meets the minimum standards for tree replacement, but the function of providing any buffering from the noise and glare of lights from the interstate highway has been severely reduced. 5. The Subsurface Exploration and Geotechnical Engineering Report, prepared by Jason Engineering Inc., identified that in the process of boring test pits for soils analysis, buried debris was encountered in Test Pit #6, which corresponds to proposed Lots 4 and 5 of the preliminary plat. The scope of work did not entail an environmental assessment of the site and the test pit was a small bore to 8-10 feet only. The materials found in that area were old tires, building and/or wood debris, and fill materials. It is not known what the size of the buried debris area is or the exact content of the buried debris. Mitigation will be required to excavate and assess the area to determine whether any hazardous materials are found in the burial site and before the proposed mass clearing and grading takes place. 6. The "Final Staff Evaluation for Environmental Checklist, File No. 074033q-00-SE" is hereby incorporated by reference as though set forth in full. i o 3lg CONCLUSIONS OF LAW Federal Way's comprehensive plan policies adopted by Federal Way, and contained within the Federal Way Comprehensive Plan (FWCP), serve as a basis for the exercise of substantive SEPA authority to Preliminary Plat of Steel Lake Crest File #07-103898-00-SE / Doc ID 46899 Mitigated Determination of Nonsignificance (MDNS) Page 2 approve, condition, or deny proposed actions applicable to potential adverse environmental impacts resulting from this project. The following components of the FWCP support the conditions for the development. NEG1: To preserve the City's natural systems in order to protect public health, safety, and welfare, and to maintain the integrity of the natural environment. NEP 1: Protect and restore environmental quality through land use plans, surface water management plans and programs, comprehensive park plans, and development review. NEP2: Preserve and restore ecological functions, and enhance natural beauty, by encouraging community development patterns and site planning that maintains and complements natural landforms. NEP3: To the maximum extent practical, the City's future actions will be consistent with the goals and policies of this chapter of the FWCP. NEP4: The City should work in concert with internal departments, state, and regional agencies, as well as with neighboring jurisdictions and tribes, to protect sensitive areas and the City's natural environment. NEG12: Develop programs and/or regulations to address noise pollution in all areas of the City. NEP71: The City should develop and adopt construction standards to mitigate noise generated by SeaTac Airport and Interstate 5, as well as other major arterials. SEPA CONDITIONS Based on the above policies, the following mitigation measures are required to minimize identified potential significant adverse impacts: If mass clearing and grading is approved for the preliminary plat as proposed, then the area of Test Pit #6 (proposed Lots 4 and 5), as identified in the Geotechnical Engineering Report, shall be excavated to determine the contents and extent of an identified debris burial. If hazardous or significant solid waste materials are discovered, then the applicant shall work with the King County Department of Solid Waste and the Washington State Department of Ecology to clean up the site and properly dispose of the debris before commencing the clearing and grading for the rest of the development site. 2. To meet HUD criteria for noise levels acceptable for residential development and to mitigate potential impacts of noise from Interstate 5 to the development and the surrounding community, the following mitigation measures are recommended by SSA Acoustics, LLP in the Environmental Noise Study conducted June 1, 2007: a) Exterior Construction Mitigation Standard construction methods that meet current energy code requirements provide a Noise Level Reduction (NLR) of 20 dB, which is adequate for exterior Ldn levels that are 65 dBA or less. Since the exterior Ldn levels are above 65 dBA, additional construction methods are necessary to meet the interior Ldn of 45 dBA. To achieve the 45 dBA Ldn requirement, the exterior envelopes (walls, windows, doors) of the residential units must be constructed to provide a 25dB Noise Level Reduction (NLR). (See attached Table 2.) Preliminary Plat of Steel Lake Crest File #07-103898-00-SE / Doc ID 46899 Mitigated Determination of Nonsignificance (MDNS) Page 3 b) Noise Barrier Mitigation To provide noise barrier mitigation to meet the exterior noise level condition, and thus the interior noise condition, a noise barrier shall be constructed between Interstate 5 and the proposed residences. The goal is to reduce the outdoor noise level by 5 to 7 dB, resulting in a 62 to 64 dBA Ldn, which meets the HUD 65 dBA Ldn Exterior Noise Standard. In turn, the reduction of the outdoor day -night average noise level to 65 dBA or less with normal construction would result in an indoor day -night noise level of 45 dBA or less. The sound attenuation characteristics of a noise barrier are based on the geometry of the barrier relative to the source and receiver locations and the frequency of the source noise. This MDNS is issued under WAC 197-11-340(2). The lead agency will not act on this proposal for 14 days from the date below. Comments must be submitted by 5:00 p.m. on October 20, 2008. Unless modified by the City, this determination will become final following the above comment deadline. Any person aggrieved of the City's final determination may file an appeal with the City within 14 days of the above comment deadline. You may appeal this determination to the Federal Way City Clerk, no later than 5:00 p.m. on October 31, 2008, by a letter stating the reason for the appeal of the determination. You should be prepared to make specific factual objections.

The applicants will be required to construct an 18, 449 stormwater detention pond in the northeast corner of the plat; a 329 square foot landscaping tract along Military Road South; a 3,364 square foot and an 868 square foot landscaping buffer along the front of 28'h Avenue South; and a 3,661 square foot pedestrian pathway to connect to Military Road South. The applicants propose significant grading on site, thus removing a majority of the vegetation, excluding many significant trees. STAFF EVALUATION OF ENVIRONMENTAL CHECKLIST Following are staff responses to the elements of the environmental checklist (attached) indicating whether or not City staff concurs with the applicant's response to the checklist item, or staff clarification or amendment of the response. A. BACKGROUND 1-3. Concur with the checklist. 4. First checklist completed July 11, 2007, but revised May 30, 2008, after reviewed by the Public Works and Planning staff. 5-9. Concur with the checklist. 10. Applicant's agent responded that additional government approvals were: final plat approval; right-of-way permit for road improvements; a WSDOT Discharge Permit; aNPDES permit from the Department of Ecology; and building permits for individual residential structures. The agent did not include a potential right-of-way permit from WSDOT for location of the pond and pedestrian pathway; a Forest Practice Permit from the Department of Natural Resources; and a demolition permit to remove the existing structures. B. ENVIRONMENTAL ELEMENTS Earth a. Concur with the checklist. b. Originally stated slopes were 9%, but after review of topographic information, it was determined that there were some areas where slopes were around 50%, although the applicant stated this was the result of previous on -site grading. c-d. Concur with the checklist. e. The applicant proposes to do a mass grading of the site to even out slopes and fill from previous development on the site. The Federal Way City Code (FWCC) states that grading should be kept to a minimum to allow for the placement of the infrastructure such as roads Steel Lake Crest Preliminary Plat File #07-103898-00-SE / Doc. ID 46823 Final Staff Evaluation for Environmental Checklist Page 2 and utility lines. Also, FWCC 20.179(c) states that, "lots created on slopes of 15% or greater shall minimize grading and shall not result in extensive use of retaining walls. Slopes are to be measured in their natural state." The applicant's agent states that in order to construct the infrastructure and pond, the site needs to be severely graded to allow this to happen. However, the applicant has not addressed the fact that there are slopes of 15% and greater on some areas of the property and the proposal includes significant grading in these areas. These issues will be addressed by city code. Finally, test pit exploration identified a source of fill on proposed Lots 4 and 5 was buried debris such as scrap wood, used tires, and other fill materials. The extent and full content of the buried debris is not known at this time. The applicant's agent said excavation of all buried materials will take place prior to the grading project taking place. f-g. Concur with the checklist. Go PM h. Do not concur with the checklist. The erosion control plan needs to besigned and submitted for review and approval as part of preliminary plat approval. The final plan needs to be submitted, reviewed, approved, and installed during the engineerin review and BEFORE final plat approval. 2. Air a-b. Concur with the checklist. C. Concur with the checklist. The comment says watering will be utilized. However, since this project is proposing to do mass grading and is located between a residential neighborhood and the I-5 corridor, a watering truck should be kept on site during the entire grading process to assure that particulate matter does not affect visibility on the highway or adversely impact ambient air quality in the neighborhood. 3. Water a.1. Concur with checklist with the addition that project lies within 200 feet of Steel Lake, a shoreline of significance. Because the applicant is required to construct frontage improvements within the right-of-way, a small portion of the project will take place within 200 feet of the shoreline. Because the area of the improvements was not considered consequential, the applicant was granted a shoreline exemption for the required road improvements. a.2-6 Concur with the checklist. b.l . Concur with the checklist. b.2. The existing three homes have on -site septic systems. At time of demolition and before any mass clearing and grading can take place on these parcels, the septic systems must be decommissioned by a licensed practitioner and removed in accordance with King County Health Department guidelines. c-d. Concur with the checklist. 4. Plants a-d. Concur with the checklist. Animals a. Do not concur with the checklist. The applicant listed no known birds or animals on or near the site. However, the proposal lies within 200 feet of Steel Lake, a shoreline of significance, which is stocked with trout and/or game fish every year by the Department of Fish and Wildlife. In addition, water fowl are on or within Steel Lake Park that are mostly resident species. Steel Lake Crest Preliminary Plat File #07-103898-00-SE / Doc ID 46823 Final Staff Evaluation for Environmental Checklist Page 3 b-c. Concur with the checklist. d. The pedestrian pathway and landscaped areas may not attract birds or wildlife because of the species being planted. They were not required to provide habitat areas for wildlife. 6. Energy and Natural Resources a-c. Concur with the checklist. 7. Environmental Health a. Do not concur with the checklist. Preliminary exploration has identified there is construction debris located in the north end of the properties. The full extent of the debris area or contents is not known at this time. The area must be excavated and debris taken off site before any significant grading or clearing taking place on the property. If hazardous materials are discovered in the burial site, then the debris must be properly disposed of in accordance with King County Solid Waste Department and possibly Washington State Department of Ecology guidelines. b. Do no concur with the checklist. The noise study identified two choices for the applicant: build a large berm or retaining structure; or require that the houses be constructed of soundproofing materials. The applicant has not specified which will be constructed. Land and Shoreline Use a-c. Concur with the checklist. d. Three houses, one shed, a barn, a swimming pool, and three septic tanks will all be demolished and removed from the site. e-f. The zoning of this property is RS-7.2, and the comprehensive plan designation is High Density, Single Family Residential. g-1. Concur with the checklist. 9. Housing a-c. Concur with the checklist. 10. Aesthetics a-c. The height limit in this zone is 30 feet. If on a slope, the height is measured as an average of the uphill grade to the proposed basement grade, and the average cannot exceed 30 feet. The applicant will be designing a number of homes with daylight basements on areas with slopes. The height of each structure will be addressed during building permit review. 11. Light and Glare a-c. Concur with the checklist. d. With the removal of a significant number of trees on the properties, any buffering from the glare of lights from the I-5 corridor will be significantly reduced. There will be eight of 52 existing trees retained on the seven lots bordering the I-5 corridor. 12. Recreation a-c. Concur with the checklist. 13. Historic and Cultural Preservation a-b. Concur with the checklist. C. If any cultural items are uncovered during excavation, clearing, and grading, the local tribes should be notified, in addition to the Washington State Historical & Archeological Society. Steel Lake Crest Preliminary Plat File #07-103898-00-SE / Doc ID 46823 Final Staff Evaluation for Environmental Checklist Page 4 14. Transportation a-g. Concur with the checklist. 15. Public Services a-b. Construction of 25 additional houses in a residential neighborhood will add impacts to public services for fire, police, and utility use. Such construction will also generate new students in the school system, additional use of parks, and increased traffic and use of streets. The applicant will be required to address school impacts and pay fees as requested by the school district at final plat stage. The use of parks and open space were reviewed at preliminary stage and will be assessed as part of the building permit process and any open space requirements will be paid before final plat approval. Traffic impacts and street improvements have been addressed during the preliminary review and improvements will be required to be put in place during engineering review of the plat. 16. Utilities a-b. Concur with the checklist. CONCLUSION The lead agency for this proposal has determined that the proposal for a residential subdivision project does not have probable significant adverse impact on the environment and an Environmental Impact Statement (EIS) is not required under RCW 43.21 C.032(2)(c). This decision was made after review of a completed environmental checklist and other information on file with the lead agency. The information is available to the public upon request. The City reserves the right to review any future revisions or alterations to the site or the proposal in order to determine the environmental significance or nonsignificance of the project at that point in time.

Due to the fact that a 20' pathway would require a lot layout that would not be marketable, we are seeking your thoughts and/or approval of our proposal to reduce the pathway to 14' . Anything wider than that would necessitate our losing another lot in order to make the property meet suggested minimum builder standards. We feel that this request will meet the intent of the City's requirement, yet allow us to retain a 28-lot subdivision —a win -win situation. As we have stated in the past, we are developing the property we have lived on for the past 30 years. And as you know, engineering costs are quite expensive.

ENVIRONMENTAL CHECKLIST PURPOSE OF CHECKLIST The State Environmental Policy Act (SEPA), Revised Code of Washington (RCW) Chapter 43.21C, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide infornation to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS This environmental checklist asks you to describe some basic information about our proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply." Complete answers to questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist qi--stions apply to al parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NON -PROJECT PROPOSALS Complete this checklist for non -project proposals, even though questions may be answered "does not apply." In addition, complete the Supplemental Sheet for Non -Project Actions. For non -project actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

None are pending at this time. 10. List any government approvals or permits that will be needed for your proposal, if known. Bulletin #050 — December 22. 2005 Page 2 of 17 k:\Handouts\Environmental Checklist The project will require a final plat approval, a right-of-way permit for the road improvements, a WSDOT Discharse Permit, a Dept. of Ecology NPDES permit and individual building permits for the residential structures. 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. The proposed project site consists of four parcels (Parcel Numbers 0921049182, 0921049183, 0921049096 & 0921049161) which are located on the east side of the 306th block of 28'h Avenue South. The project site covers the area between 281h Avenue South and the I-5 right- of-way. The pro�aL'll;t to divide the four parcels, which comprise approximate[ 292,892 square feet or�6.7722 acr-es prior to dedications, into ide ial lots an acts The existing three residences, including all accompanying structures, will be removed and new wood framed homes will be built on each proposed lot. The tracts will contain a stormwater detention facility, a pedestrian pathway and three separate landscape buffers. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project is located in a portion of the NE'/a of Section 9, Township 21 North, Range 4 East, WM. The addresses of the three existing on -site residences are 30614, 30642 & 30646 28th Avenue South. The parcels legal descriptions are as follows: PARCEL 0921049182 THE SOUTH HALF OF THE NORTH HALF OF THE SOUTHWEST QUARTER OF THE NORTHEAST QUARTER OF THE NORTHEAST QUARTER OF SECTION 9, TOWNSHIP 21 NORTH, RANGE 4 EAST, W.M., IN KING COUNTY, WASHINGTON; EXCEPT THE WEST 30 FEET THEREOF FOR COUNTY ROAD; AND EXCEPT THAT P R FOR STATE HIGHWAY AS CONVEYED IN DEED RECORDED UNDE R R,pdN , NII agjB 4986687.

ENVIRONMENTAL ELEMENTS EARTH a. General description of the site (circle one): flat, rolling, hilly, steep slopes, mountainous, other. The best general description of the site would be continuous sloping, with an average slope of 9.5% from the southwest corner to the northeast corner. b. What is the steepest slope on the site (approximate percent slope)? There are a couple of small areas where the slopes. exc gftj�� These areas are not naturally occurring, but are a manmade result of filling from the corresponding on -site residences. The grading plan for the proposed project will eliminate all of these areas. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, mulch)? If you know the classification of agricultural soils, specify them and note any prime farmland. Per the 2005 City of Federal Way Regional Soils Map, which is based on information presented in the 1973 Soil Conservation Service Survey of King County, Alderwood gravelly sandy loam type soils are mapped for the project site. The western one-half of the project is comprised of Alderwood (AgB) soils and the eastern half of the project has Alderwood (AgC) soils. Both soil types are Hydrologic Soils Group (HSG) C. Field investigation ha(7 uncovered an area of discarded old tireaand wood debris along the north plat boundary by The geotechnical engineer will require that the tires and debris be removed. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. There were no areas of observed unstable soils observed on or adjacent to the site during Bulletin #050 — December 22, 2005 Page 4 of 17 k:\Handouts\Environmental Checklist any of the project site visits and there is no history of any that have been discovered. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. The project obtained the services of Earthwork Services, Inc. to calculate preliminary earthwork quantities. Their report dated May 2, 2007, is based on a preliminary grading plan completed by Schweikl & Associates, and concludes that the project will be a cut site. Calculated values are I2,8 rnhic yar_ds��,1Q4 cuUc yards of fill and 5,152 cubic yards of strip in s. Further refinement of the grading plan is possible in attempting to create a balanced site. The contractor should also attempt to spoil the stripprtgs on -sit- where ever possible. If off-s' "tructural fill material becomes necessary, the material would be taken from th closet �vailable source at the time of project construction. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. As with any glacial till soil there is the possibility of erosion when disturbed by construction activities, especially with the use of heavy construction equipment on uncompacted material. The site is required to prepare and install an erosion cQntral plan that will be reviewed and approved by the City of Federal Way to address the possibility of erosion. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The project is proposing a maximum impervious coverage of 53 6 a using the modeling criteria from the King County Storm Water Design Manual. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any. J As part of the final design plan, the project is required to prepare and install an Erosion/ Sedimentation on rol Plan.. The pia!!, which ' 'wed and approved bathe Ciiy of Federal Way, will address the issue of,ermian —zwLpravide measures fore ce a�dloz minimize its effects. Among the proposed measures included in the Erosion/Sedimentation Control Plan will be a temporary rock constructiion a -ace, siltation fencing, catch basin sediment protection, interceptpr swales, sediment traps, straw bales, mulching and hydroseeding. Also included with the plan is a recommended construction sequence and a copy n he City of Federal Way's standard erosion/sedimentation control notes. It is the responsibility of the contractor to adhere to the plan and maintain in a functional manner all erosion control facilities. 2. AIR a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. The grading activities proposed at the site will cause dust particulate to be emitted to the air. Vehicles and equipment used during all phases of construction can be a potential source of emissions. When the project is completed, the site will generate emissions that are typical of any other modern residential neighborhood. Vehicle emissions from the residents automobiles, emissions from lawn and landscaping maintenance equipment, certified wood stoves and/or fire places, furnaces, barbeques, etc, are all potential sources of air emissions. Bulletin #050 — December 22, 2005 Page 5 of 17 k:\Handouts\Environmental Checklist However, the quantities are unknown. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. Vehicles using 28th Avenue South and Interstate 5, adjacent to the sites west and east boundaries respectively, can be a source of emissions or odor. However, it is not anticipated that these off -site vehicle sources of emissions will impact this proposal. There are no other known sources of odor or emissions in the vicinity. c. Proposed measures to reduce or control emissions or other impacts to air, if any. Unwanted dust particulate can be controlled to a certain extent by the application of water 1 before and during grading activities. Also, by keeping the temporary construction entrances ' clean and functioning properly, along with regular street sweeping of 28th Avenue South, rI�Y" dust generated from displaced material on roadways can be kept to a minimum. It is ` assumed the construction vehicles used will be equipped with factory -installed mufflers and spark arresters that would control excessive emissions. 3. WATER a. Surface. 1) Is there any surface water body on or in the immediate vicinity of the site (including year- round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. There are no surface water bodies or wetlands located on the site. There are however, two lakes in the vicinity of the project. To the west, across the 281h Avenue South right-of-way is Steel Lake. At its closest point, the lake is approximately 200 feet from the extreme northwest corner of the proposed site. East of the site, across the I-5 right-of-way lies Dolloff Lake. From the northeast corner of the site it is approximately 1,000 feet to the northwest portion of the lake. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. ,�,'� �1f,,1ru Yes. The project is required by the City of Federal Way to do half street frontage W improvements on 281h Avenue South, and a portion of these improvements will fall within 200 feet of Steel Lake. Approximately 40 linear feet of vertical curb, 200 square feet of concrete sidewalk and 40 square yards of asphalt paving, along with extending an existing storm drainage pipe 10 feet will occur within the 200 foot+ t' boundary of the lake. This work is all off -site of the proposed project, only a small amount of landscaping (10 square yards) and some minor grading (less than 10 cubic yards of on -site movement) actually occur on -site and within 200 feet of the lake. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. No fill or dredge material will be placed or removed from either of the lakes. Bulletin #050 — December 22, 2005 Page 6 of 17 k:\Handouts\Environmental Checklist 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. None anticipated. Both lakes receive storm water runoff from the site as part of the existing drainage system. The proposed project will continue its natural discharge to these water bodies per the City of Federal Way's Storm Water Drainage Manual. 5) Does the proposal lie within a I00-year floodplain? If so, note location on the site plan. No, the project does not lie within a 100 year floodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No b. Ground. 1) Will ground water be withdrawn, or will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known. No 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: domestic sewage; industrial, containing the following chemicals...; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. There are no proposed discharges of waste material to the ground from any source. The site proposes a low pressure forced main sanitary sewer collection system for all lots and conveyance to the existing Lakehaven Utility District gravity sanitary sewer line at South 309th Street. From there the effluent is conveyed to an offsite treatment facility. Currently the exi . esi cesAay_e w1yate on-si_ to epfLc systems. The project proposes to have these residences removed, at that time the proper steps will be taken to abandon their septic systems. c. Water Runoff (including stormwater) 1) Describe the source of runoff (including stormwater) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. This project has the somewhat uncommon situation where it actually falls within two separate drainage basins. Essentially the off -site portion of the project (the 28" Avenue South right-of-way) is part of the Lower Puget Sound drainage basin, and the on -site portion is part of the Mill Creels drainage basin. Therefore runoff from the project site is divided two ways. Stormwater runoff from the 281h Avenue South half street frontage improvements will be collected, treated via a catch basin filtersystem, and released to the existing conveyance system that discharges west into Steel Lake. Runoff from the remainder of the site will be collected by means of a tightline conveyance system to a proposed ofsite stormwater detention/water quality wetpond located in a separate tract at -the northeast corner of the project site. Bulletin #050 — December 22, 2005 Page 7 of 17 kAHandouts\Environ mental Checklist Discharge from the wetpond is daylighted to the Military Road South right-of-way, the project on -sites natural discharge location, where it flows east, enters an existing storm drainage conveyance system that passes under the I-5 right-of-way and daylights before eventually entering Dolloff Lake. 2) Could waste materials enter ground or surface waters? If so, generally describe. Naturally with a project of this type and size the possibility exists of accidental contamination. Spills and carelessness during construction could occur. 2_8 new residential homes will be built and the new residents all could potentially be sources for waste entering ground or surface water. Everything from poor handling of landscaping products (chemicals and fertilizers) to painting practices to leaky automobiles and their care. To our knowledge, of the things that are under the projects control, there are no other known sources of contaminants associated with this proposal. The project will also be required to prepare plans for, obtain approval of, and install a water quality facility operating in conjunction with a detention system. The parameters of which are governed by the current surface water design manual adopted by the City of Federal Way. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any. The project proposes to implement techniques consistent wi a City of Federal Way's Storm Water Design Manual to minimize all impac do stormwater runoff. All on -site stormwater runoff generated from this project will be collected, detained, and treated in a combined detention/water quality wetpond facility prior to discharge. The wetpond discharge will be controlled per the design manual, to discharge at a rate no greater than the predeveloped sit�s)rate of discharge. The wetponds outlet location, east into the Military Road South right-of-way, closely approximates the on -sites natural discharge location. The designed overflow route also follows this same path. All of the projects'off-site generated stormwater runoff will also be collected and treated. Treatment will be provided by settling in the water quality storage in the detention facility. Runoff will then be released into the existing stormwater conveyance system, where it flows west and discharges to Steel Lake. 4. PLANTS a. Check or circle types of vegetation found on the site. X deciduous tree: alder, maple, aspen, other (birch, madrona) X evergreen tree: fir, cedar, pine, other X shrubs X grass pasture crop or grain wet soil plants: cattail, buttercup, bulrush, skunk cabbage, other waterplant., water lily, eelgrass, milfoil, other other types of vegetation b. What kind and amount of vegetation will be removed or altered? Most trees and vegetation located on the project will be removed to allow for the construction of the proposed internal road, the 281h Avenue South frontage improvements, Bulletin 4050 — December 22, 2005 Page 8 of 17 k:\Handouts\Environmental Checklist new utility services and the proposed new homes. The project does propose retaining significant trees located near the perimeter of the site, primarily along the eastern boundary line. Others will be retained adjacent to the northern and southern boundary lines. The project has obtained the services of The Roper Company, registered landscape architects, to conduct a significant tree inventory and create a landscape plan which will best utilize the existing native plant life. c. List threatened or endangered species known to be on or near the site. To our knowledge, there are no threatened or endangered plant species on or near the site. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any. t completion Upon of construction of the single-family residential homes the disturbed areas P within the lots will be landscaped with lawn and/or mulched garden planting beds. burin ' construction siltation fencing, tree retention fencing and limits of construction fencin all be utilized to identif protect and prevent intrusion' are =J_5 �n vegetation are to be i. preserved. . L_ — The project has obtained the services of The Roper Company (registered landscape architects) to provide a landscape plan for Steel Lake Crest. Included in this plan will be a significant tree inventory, tree plantings along the plat street right-of-ways, and screening landscaping for the detention wetpond tract and the required 10 foot landscape buffers. Landscaping in the buffers will be to the City of Federal Way's Type III landscaping criteria. 5. ANIMALS a. Circle any birds and animals which have been observed on or near the site or are known to be on or near the site. I / birds: hawk, heron, eagle, songbirds, other chickadee robin wren mammals: deer, bear, elk, beaver, other (squirrel, raccoons mice fish: bass, salmon, trout, herring, shellfish, other none b. List any threatened or endangered species known to be on or near the site. To our knowledge, there are no threatened or endangered animal species on or near the site. c. Is the site part of a migration route? If so, explain. The site is located within the boundaries of the western flyway. However, migrating bird populations have not been known to visit the site d. Proposed measures to preserve or enhance wildlife, if any. No specific wildlife preservation measures are proposed by the project, however the three proposed landscape tracts, along with portions of the proposed Pedestrian Pathway tract will provide some areas of landscapecIxenspace wifhin_the develn meat where birdAAnd other small wildlife species ma fora 1 a hitai. Also, while most of the native 1�4 vegetation w e removed during the installation of infrastructure and the construction of homes, once finished the resident's yards may offer some benefits to certain wildlife species. Bulletin #050 — December 22. 2005 Page 9 of 17 k:\Handouts\Environmental Checklist 6. ENERGY AND NATURAL RESOURCES a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. The primary energy sources required to meet the energy needs of the proposed plat is electricity and natural gas. Sufficient amounts of which would be needed to maintain a comfortable lifestyle and environment within the bounds of single family residential dwellings b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. No, it is not anticipated that this project will affect the potential for adjacent properties to use solar energy. The building heights will not exceed the maximum which is allowed in the RS 7.2 zone. The proposed structures will not be located in such a way that they will affect the exposure of any adjacent existing structure, especially those adjacent structures seeking the maximum benefits afforded to solar users obtained from the preferred southern exposure What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any. 19 The homes will be built to meet or exceed current building and energy codes. 7. ENVIRONMENTAL HEALTH a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste that could occur as a result of this proposal? If so, describe. Typically, a residential development is not a source of environmental health hazards. However, the risk of fire is always present within a residential development 1) Describe special emergency services that might be required. While not anticipated to occur, the services of local emergency service prodders may be required at some time. There are no "special needs" emergency service requirements associated with this project outside of the normal level of service � 15 provided to the surrounding similar residential neighborhoods aaif� 2) Proposed measures to reduce or control environmental health hazards, if any. Outside of the installation of a fire hydrant within the development, there are no additional measures provided. Noise. 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment operation, other)? Vehicular traffic noise is generated on 28th Avenue South along the west project boundary and from Interstate 5 in the east. The City of Federal Way is requiring a Bulletin #050 — December 22, 2005 Page 10 of 17 k:\Handouts\Environmental Checklist noise study be completed that documents freeway noise levels and identifies appropriate measures to mitigate the impacts on the development. The project has obtained the services of SSA Acoustics to prepare a site acoustical analysis. 2) What types and levels of noise would be created by or associated with the project on a short-term or long-term basis (for example: traffic, construction operation, other)? Indicate what hours noise would come from the site. During the short-term, construction activity at the project site can and will vary considerably. In addition, because the noise produced on the site depends on the equipment being used, the levels could easily vary from day to day. Maximum construction noise levels can be expected to range from 65 to 89 dBA with an average value of approximately 85 dBA. Minimum noise levels can be expected to have a wider range of 57 to 88 dBA with an average value of 78 dBA (based on a construction activity noise model, described in Noise from Construction Equipment and Operations, Building Equipment, and Home Appliances). Noise associated with construction operations on the site will occur roughly between the hours of 7:00 a.m. to 6:00 p.m., Monday through Friday and the possibility of some Saturdays. Long-term noise impacts will result from increased vehicular traffic at the site and from the average generated noise levels associated with a typical single-family residential development. 3) Proposed measures to reduce or control noise impacts, if any. Noise impacts associated with the construction phases of the project will be limited in duration. To mitigate general noise impacts during the grading phase, measures such as using and regularly maintaining efficient mufflers and quieting devices on all construction equipment and vehicles can be anticipated. No measures to mitigate noise impacts during the building phase are proposed. Construction hours will be limited to the normal workday, 7:00 a.m. to 6:00 p.m. Proposed measures to mitigate noise generated by the nearby freeway should be outlined in the site acoustical analysis being prepared by SSA Acoustics. Common noise preventive building practices such as using special windows, extra insulation sound deadening materials, etc may be used, ore passive measures including choosing house plans that hinder the intrusion of noise, and locatin a homes on the lots to best block sound from ce 'rections could he a #[ i,5. Also landscaping and fencing techniques are other possibilities. 8. LAND AND SHORELINE USE a. What is the current use of the site and adjacent properties? The current land use for the site is single family residential, however with only three residences on the 6.72 acre site, it does not come close to the density allowed under the cities zoning classification. The adjacent properties to the north, south and west all have the same zoning and, except for the ills ally a e in commercial lumbin .cow locate n the east balf ofALtmW&jwrtbJtouDdaryJine, all are in single family residential land use. Directly east of the site, the adjaurnxng roperty is state owned right-of-way containing I-5. b. Has the site been used for agriculture? If so, describe, Bulletin #050 — December 22, 2005 Page 1 I of 17 UHandouts\Environmental Checklist To our knowledge, the project parcel has never been used for crop production, however, timber harvest may have occurred at some time in the past. c. Describe any structures on the site. ' . There are three existing residences (homes) on the project site. The residence at 30614 28`h l� Ave S. consists of a single house. The residence at 30642 281h Ave S is a house with a built-in back yard pool and a separate outbuilding/shed. The third residence has a house and a larger out wilding/ barn. d. Will any structures be demolished? If so, what? �/ Yes, all existing structures are to be removed. e. What is the current zoning classification of the site? + t RS 7.2, 1 unit per 7,200 square feet. f. What is the current comprehensive plan designation of the site? High -Density Single Family Residential. g. If applicable, what is the current shoreline master program designation of the site? For the small area in the northwest corner of the site which falls within 200 feet of Steel Lake, the shoreline designation is urban. h. Has any part of the site been classified as an environmentally critical area? If so, specify. The extreme northwest corner of the site falls within 200 feet of Steel Lake and is therefore part of the City of Federal Way's Shoreline Management Plan. No other mapped Critical Areas exist on the site. There are a few small areas on the site where the slope exceeds 40%. None of these steep slopes are naturally occurring, but are the result of grading or filling associated with the existing residences. i. Approximately how many people would reside or work in the completed project? The proposed plat of 28 lots will provide housing for approximately 70-120 individuals Approximately how many people would the completed project displace? k. Proposed measures to avoid or reduce displacement impacts, if any. None, the people being displaced from the site are the applicants of this document, and the owners of the project. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any. The City of Federal Way has a comprehensive land use plan that covers the site and the Bulletin #050 — December 22, 2005 Page 12 of 17 k:\Handouts\Environmental Checklist adjacent parcels. All the surrounding parcels, along with the project site have a land use designation of Single Family Residential. 9. HOUSING a. Approximately how many units would be provided, if any? Indicate whether high, middle, or low- income housing. 28 new middle to high income single-family residences will be provided by projects end b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low-income housing. The three existing middle income single family residences would be eliminated. c. Proposed measures to reduce or control housing impacts, if any. The proposed plat will create housing consistent with the principals and mandates of the Growth Management Act (GMA). The GMA strives to increase existing urban densities to allow for the full utilization of existing utilities, services and infrastructure and to increase the functionality of mass transit while protecting the rural environments from urban sprawl. 10. AESTHETICS a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? The tallest structure will be two stories and less than 30 feet in height with a wood and/or vinyl exterior. b. What views in the immediate vicinity would be altered or obstructed? The project should not compromise the views from adjacent properties. The view of the site, of course, will be altered to that of a single-family housing development. The required landscape buffers along 281h Ave S and Military Road S, c. Proposed measures to reduce or control aesthetic impacts, if any. The proposed plat will include architecturally compatible homes built by a single builder meeting the requirements of the City of Federal Way Building Guidelines. The interior road will be built to the City of Federal Way's public road standards (Section W) and the project proposes the creation of aesthetically pleasing front yard landscaping for the single- family residences. 10 foot landscape buffers will provide screening between the development and those traveling on the arterials adjacent to the project. Also, The Roper Company (registered landscape architects) has been obtained to provide a landscape plan for Steel Lake Crest. Included in this plan is landscaping and tree plantings for along the adjacent street right-of-ways, landscaping of the detention/wetpond tract and screening landscaping for the landscape buffers. 11. LIGHT AND GLARE a. What type of light or glare will the proposal produce? What time of day would it mainly occur? Bulletin #050 — December 22, 2005 Page 13 of 17 k:\Handouts\Environmental Checklist Light and glare is the result of reflective surfaces from the glazing and building materials, exterior building lights, and street lights. During evening and night time hours, exterior building lights and street lighting will be designed to minimize the dispersal of light beyond the project. Properly designed and placed lights, specifically chosen to illuminate target �J areas with downward emitting luminaries, can be used to light intended areas without pe having negative impacts on others. The occurrence of light impacts would be anticipated from dusk to dawn. Some glare impacts may be present during the daytime associated primarily with normal -residential window glazing. The impacts from glare may also occur seasonally. b. Could light or glare from the finished project be a safety hazard or interfere with views? It is highly unlikely that glare or light from the project site will interfere with views, affect wildlife, create safety problems, or have any other adverse impacts. The proposed project will have the same accompanying light and glare impacts that are consistent with the other adjacent residential developments. Streetlights and other outdoor lighting are intended to promote safety rather than create a safety hazard. c. What existing off -site sources of light or glare may affect your proposal? �,�� 'lip tix There are no known off -site sources of light or glare that are anticipated to affect this proposal. Streetlights along 28th Avenue South and vehicular lights from cars on 1-5 and 281h Avenue are ti 1 tji� present, but not unusual in any way or inconsistent with what exists in neighboring developments. !� d. Proposed measures to reduce or control light and glare impacts, if any. l r.� r A J� l Using exterior building lights of low intensity and directing street lights to point downward M1 l lr `ti are typical ways to control light and reduce glare. are used for safety and security purposes. Landscaping techniques can also be used to provide screening of light between homes, other�� adjacent developments and vehicles as well. The positive affects of light however, mainly safety and security (especially at night), must be weighed when proposing measures to control it. 12. RECREATION a. What designated and informal recreational op! ,nrtunities are in the immediate vicinity? Steel Lake Park, The Commons at Federal Way b. Would the proposed displace any existing recreational uses? If so, describe. No, the project will not displace any recreational opportunities c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant, if any. No measures are proposed, however the applicants will be paying a fee -in -lieu -of providing on -site open space which benefits the City of Federal Way Parks, Recreation and Cultural Services (PARCS) department. 13. HISTORIC AND CULTURAL PRESERVATION Bulletin #050 — December 22, 2005 Page 14 of 17 k:\Handouts\Environmental Checklist a. Are there any places or objects listed on, or proposed for, nation, state, or local preservation registers known to be on or next to the site? If so, generally describe. None known to exist. b. Generally describe any landmarks or evidence of historic, archaeological, scientific, or cultural importance known to be on or next to the site. None known to exist. c. Proposed measures to reduce or control impacts, if any. There are no measures proposed to reduce or control impacts. However, if objects are unearthed during site work that may be culturally significant, the Washington State Office of Archaeology and Historic Preservation will be notified r " La.,'_ I V16c - 14. TRANSPORTATION a. Identify public streets and highways serving the site, and describe proposed access to the existing street system. Show on site plans, if any. The only street which will service the site is 281h Avenue South, and the project is proposing a single entrance/access onto it. Besides Interstate 5 to the east, which restricts direct access, Military Road South is the only other street adjacent to the site. The City of Federal Way and the project owners have agreed not to provide vehicular access to it. A proposed footpath will allow pedestrian access between Military Road and the projects proposed internal loop road. Military Road is easily accessible from the site by traveling north two blocks on 28th Ave S, turning east onto South 3041h Street and proceeding one block. Traveling west on S 3041h St from 281h Ave S for just over a half mile will bring you to Pacific Highway South. Less than a mile to the south of the site via 28`h Ave S is South 320th Street, the main east -west arterial in the city, and access to Interstate 5. b: Is the site currently served by public transit? If not, what is the approximate distance to the nearest transit stop? Yes, Metro Transit Route 183 (south to Federal Way Transit Center, north to Kent Station) has stops along 28`h Ave S within a quarter mile of the site. c. How many parking spaces would the completed project have? How many would the project eliminate? The completed project will provide at least two exterior driveway parking spaces and two interior garage parking spaces per new residential lot proposed. For a minimum total of 56 exterior spaces added and 56 interior spaces added. The possibility exists that the homes chosen to be built will have three car garages thereby increasing the number of parking spaces accordingly: The existing residences are to be removed from the site, so the project would eliminate the approximately 18 parking spaces associated with them. Also, it should be noted that the proposed internal road will be built to the cities Section W standard, which is designed to accommodate parking on both sides. d. Will the proposal require any new roads or streets, or improvements to existing roads or streets, Bulletin #050 — December 22, 2005 Page 15 of 17 k:\Handouts\Environmental Checklist not including driveways? If so, generally describe (indicate whether public or private). Yes, an internal loop road will be constructed per the City of Federal Way's Public Works Development Standards with a Type W cross section. The internal road will be public with the 52 foot right-of-way dedicated to the city. Half street frontage improvements are also required to 281h Avenue South. The project will dedicate an additional 9 feet to the 281h Ave S right-of-way, so that the street can be improved to a Type K section. e. Will the project use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. It is not anticipated that water or rail transportation will be utilized by the project. Residents of the development most likely will use air transportation at some time. Seatac ' International Airport is located approximately 10 miles to the north, and Auburn Municipal Airport is located approximately 5 miles to the east. f. How many vehicular trips per day would be generated by the completed project? If known, indicate when peak volumes would occur. According to the ITE Trip Generation Manual, Seventh Edition, page 269, Land Use Code 210, Single -Family Detached Housing, the average number of trips generated per dwelling unit is 9.57. Multiplying 9.57 by the total number of lots, 28, yields a result of approximately 268 total vehicle trips per day for the completed project. Because the project is removing three existing residences (dwelling units), the net or new vehicular trips generated by the completed project is 239 (9.57 multiplied by 25). Although the exact time of peak flow is unknown, they generally occur on weekdays, between the hours of 7 & 9 AM and 4&6PM. g. Proposed measures to reduce or control transportation impacts, if any. Besides the required half street frontage improvements to 281h Avenue South, a site distance anal siis deterrrxned that the project install a two v�+ay left turn lane in 28th Ave S to providp saaccess_to. and from the site. The project will also pay a traffic mitigation fee based on a concurrency analysis which the project will pay the City of Federal Way to perform. The traffic mitigation fee will go towards funding transportation projects deemed necessary to raise the level of service in areas impacted by this project. 15. PUBLIC SERVICES a. Would the project result in an increased need for public services (for example: fire protection, police protection, health care, schools, other)? If so, generally describe. Yes. Whenever a residential development is constructed, the need for public services, such as police and fire protection, increases. Federal Way School District No. 210, City of Federal Way Police Department, and South King Fire and Rescue serve the site. b. Proposed measures to reduce or control direct impacts on public services, if any. At the time of final plat mitigation fees are paid to the city, many,of g towards funding public services. Public Services also benefit from the increased c❑ ' ution to the property tax base. i Ikr c -k 6.r 16.

The report presents measurement results, guidelines and criteria for residential noise levels and mitigation measures to meet the criteria. DESCRIPTORS Sound consists of minute vibrations, which travel through a medium, such as air, and are sensed by the human ear. The ear perceives these vibrations as changes in pressure and as a result sound levels are often referred to as "sound pressure levels." Sound levels are expressed in units of decibels. The term decibel implies a logarithmic ratio of the measured pressure to a reference pressure. The reference pressure refers to the lower threshold of perceptibility by the human ear. The human ear responds differently to sounds at different frequencies. This is demonstrated by the fact that we hear higher pitched sounds more easily than lower ones of the same magnitude. To compensate for the different "loudness" as perceived by humans, a standard weighting curve is applied to measured sound levels. The weighting curve represents the frequency response of the human ear and is labeled as dBA ("A" weighted decibels). Sound levels vary significantly depending on location and activities. People normally experience sound levels between about 30 and 90 dB(A), depending on their activity. For example, a nearby noisy vehicle, radio or power tool may produce 90 dB(A); normal conversation is about 55 to 65 dB(A); and a bedroom or quiet office is about 30 to 40 dB(A). The table below approximates human sensitivity to changes in sound level. Table 1 Changes In Sound Level Change in Change in Sound Level MB) ADDarent Loudness 1 Imperceptible (except for tones) 3 Perceptible 6 Significant 10 Twice (or half) as loud 20 4 times (or one -forth) as loud_ When measuring noise that is fluctuating over time, such as traffic noise, it is common practice to use a descriptor called the equivalent A -weighted sound level, Leq. The Leq is the constant sound level in dB(A) which contains the same amount of sound energy over a given time period as the actual measured fluctuating noise event. Equivalent A -Weighted Noise Level, LEQ Leq, equivalent sound level, is the level of a constant sound that, over a given time period, contains the same amount of sound energy as the measured fluctuating sound; Day -Night A -Weighted Average Noise Level, Ldn or DNL DNL or Ldn, day -night average sound level is a descriptor that describes the continuous sound exposure for a 24 hour period with a 10 dBA adjustment added to sound levels occurring during nighttime hours (10 PM and 7 AM). 222 Etruria Street, Suite 100, Seattle, WA 98109 Tel: 206,839.0819 Fax: 206.839 0824 Steel Lake Crest Plat SSA Acoustics, LLP NOISE GUIDELINES Job #: 07-2201 Page 4 of 14 The Department of Housing and Urban Development Noise Standards consider outdoor Day -Night Average Sound Levels (Ldn) below 65 dBA "acceptable" and the indoor Day -Night Average Sound Level (Ldn) goal is to riot exceed 45 dBA'. Normal construction can be expected to provide a Noise Level Reduction (NLR) of 20 dB, thus the indoor goal of Ldn less than 45 dBA can be met when the outdoor Ldn is less than 65 dBA. Additional information about the guidelines for considering noise in land use planning and control is included in Appendix I. 1 HUD Chapter 2: The Noise Regulation, 51.101 (9) Interior Noise Goals 222 Etruria Street, Suite 100, Seattle, WA 98109 Tel: 206.839 0819 Fax: 206 839.0824 Steel Lake Crest Plat Job #: 07-2201 SSA Acoustics, LLP Page 5 of 14 MEASUREMENT DESCRIPTION SSA Acoustics placed one long-term environmental noise monitor on the property which was a Larson Davis 820 (Type 1) Precision Integrating Sound Level Meter, which recorded the hourly average sound level. Short-term measurements were also conducted on -site with a Larson Davis 824 (Type 1) Spectral Analyzer. The equipment conforms to American National Standards Institute (ANSI) requirements for Type 1 instruments. The Sound Level Meters were calibrated before and after the measurements with a 1000 Hz tone at 94 dB? The environmental noise monitor was placed on top of a storage shed at 30642 28th Avenue South on Thursday May 17, 2007 to record the long-term noise levels experienced on the property and the monitor was stopped on Tuesday May 22, 2007, shown in Figure 1. Figure 1 2 Briiel & Kjaar Type 4230 Sound Level Calibrator (Calibrated by Scantek, Inc. on May 9, 2006) 222 Etruria Street, Suite 100, Seattle, WA 98109 Tel: 206.839.0819 Fax: 206.839.0824 Steel Lake Crest Plat Job #: 07-2201 SSA Acoustics, LLP Page 6 of 14 MEASUREMENT RESULTS The environmental noise monitor recorded an Equivalent A -weighted Noise Level (LEQ) for each of the 115 hours the monitor was active. The data was then reduced to a single Day -Night Average Noise Level (Ldn) for each full 24-hour period. The Day -Night Average Noise Level (Ldn) corrects for the heightened levels of perception between the hours of 10:00 PM and 7:00 AM with an additional 10 decibel weighting. The recommended exterior day -night noise level should not exceed an Ldn of 65 dBA; without additional noise reduction incorporated into the construction. Figure 2 shows the Equivalent A -Weighted Noise Level (LEQ) for each hour from May 17th through May 22nd at 30642 28th Avenue South in Federal Way, Washington, with the Ldn for each full 24-hour period shown3.

The hourly average noise levels exceeded 56 dBA during the entire four day noise monitor, with a maximum 24 hour Leq of 66 dBA and an average Leq of 62 dBA. The exterior day -night noise levels exceeded the recommended HUD guidelines. Therefore, mitigation measures will be necessary. 3 Figure 1 is included as a full page graph in Appendix 2. 222 Etruria Street, Suite 100, Seattle, WA 98109 Tel: 206 839 0819 Fax: 206 839 0824 Steel Lake Crest Plat Job #: 07-2201 SSA Acoustics, LLP Page 7 of 14 RECOMMENDATIONS The measurements at 30642 28th Avenue South in Federal Way, Washington resulted in exterior noise levels ranging between 65 and 70 dBA Ldn. Therefore, noise mitigation will be required to meet the HUD criteria. There are two options to mitigate the noise from Interstate 5 to meet the indoor noise level criteria: either by providing above -standard exterior envelope construction mitigation or noise barrier mitigation. The following are recommendations for each option to meet the recommended 45 dBA Day -Night Average Noise Level (Ldn). Exterior Construction Mitigation Standard construction methods that meet current energy code requirements provide a Noise Level Reduction (NLR) of 20 dB, which is adequate for exterior Ldn levels that are 65 dBA or less. Since the exterior Ldn levels are above 65 dBA, additional construction methods are necessary to meet the interior Ldn of 45 dBA. To achieve the 45 dBA Ldn requirement, the exterior envelopes (walls, windows, doors) of the residential units must be constructed to provided a 25 dB Noise Level Reduction (NLR). The general 25 dB Noise Level Reduction construction details are presented in Table 2. The current construction details can be reviewed to incorporate the additional noise level reduction requirements. A 25 dB NLR assumes mechanical ventilation and closed windows year round. 222 Etruria Street, Suite 100, Seattle, WA 98109 Tel: 206 839.0819 Fax: 206.839.0824 Steel Lake Crest Plat Job #: 07-2201 SSA Acoustics, LLP Table 2 25 dB NLR (Required within 65-70 DLN zones) Page 8 of 14 Brick Veneer, Masonry Blocks, or Stucco exterior walls shall be constructed airtight.

The goal is to reduce the outdoor noise level by 5 to 7 dB, resulting in a 62 to 64 dBA Ldn, which meets the HUD 65 dBA Ldn Exterior Noise Standard. In turn, the reduction of the outdoor day -night average noise level to 65 dBA or less with normal construction would result in an indoor day -night noise level of 45 dBA or less. The sound attenuation characteristics of a noise barrier are based on the geometry of the barrier relative to the source and receiver locations and the frequency of the source noise. The installation of a highway sound barrier could provide up to 7 dB of reduction from road noise with a 10 feet above road grade noise barrier. The noise barrier should be installed near Interstate 5, as shown in Figure 3.

The following notes are included in the Guidelines. Notes for Table 2 1. a) Although local conditions may require residential use, it is discouraged in C-1 and strongly discouraged in C-2. The absence of viable alternative development options should be determined and an evaluation indicating that a demonstrated community need for residential use would not be met if development were prohibited in these zones should be conducted prior to approvals. b) Where the community determines that residential uses must be allowed, measures to achieve outdoor to indoor Noise Level Reduction (NLR) of at least 25 dB (Zone C-1) and 30 dB (Zone C- 2) should be incorporated into building codes and be considered in individual approvals. Normal construction can be expected to provide a NLR of 20 dB, thus the reduction requirements are often stated as 5, 10 or 15 dB over standard construction and normally assume mechanical ventilation and closed windows year round. Additional consideration should be given to modifying NLR levels based on peak noise levels. c) NLR criteria will not eliminate outdoor noise problems. However, building location and site planning, design and use of berms and barriers can help mitigate outdoor noise exposure particularly from ground level sources. Measures that reduce noise at a site should be used wherever practical in preference to measures which only protect interior spaces. 2. Measures to achieve NLR of 25 must be incorporated into the design and construction of portions of these buildings where the public is received, office areas, noise sensitive areas or where the normal noise level is low. 3_ Measures to achieve NLR of 30 must be incorporated into the design and construction of portions of these buildings where the public is received, office areas, noise sensitive areas or where the normal noise level is low. 4. Measures to achieve NLR of 35 must be incorporated into the design and construction of portions of these buildings where the public is received, office areas, noise sensitive areas or where the normal noise level is low. 222 Etruria Street, Suite 100, Seattle, WA 98109 Tel: 206.839 0819 Fax: 206 839.0824 Steel Lake Crest Plat Job M 07-2201 SSA Acoustics, LLP APPENDIX II Page 14 of 14 ?00 'SO 0 Hourly Average Noise Levelly (dBA) N N CDA Oo O N A CDOo O O 1-10. 00 a 1% n R0 0 860 '?o 0 -10. 0 'po. .00 r ; O C o. n a Ao 00 W a O 2 4,60 a '�0 o � 's 00 °b 0 Z O 3 J 00 1160 W n o c� .-.

Pavement Design & Analysis File J. 07001-035 Site Exploration Procedures General Notes: The field exploration to determine the engineering characteristics of the foundation materials included a reconnaissance of the project site, excavating the test pits, performing field penetrometer and vane shear tests and recovering disturbed grab samples. A total of nine test pits were placed on the site. Test pits were advanced to 10 feet below the existing ground surface. Test pits were located by the field crew near as possible to the proposed building location. Schweikl and Associates supplied a site plan to locate the proposed building orientation and position the excavations. The test pits were located by the field technician by means of normal taping and pacing procedures and are presumed to be accurate to within a few feet. After completion, the pits were backfilled with excavated soils and the site cleaned and leveled as required. The types of foundation materials encountered in the test pits have been visually classified and described in detail on the logs provided in the Appendix. The results of the field penetrometer and vane shear tests, moisture contents and other laboratory tests are presented on the logs. It is recommended that the logs not to be used for estimating quantities due to highly interpretive results. Drilling & Sampling Procedures: The test pits were performed with a conventional track excavator. Representative samples were obtained from the pits at various soil intervals. The samples obtained by this procedure were classified in the field by a soils technician, identified according to pit number and depth, placed in plastic bags to protect against moisture loss and transported to the laboratory for additional testing. Laboratory Testing Program: Along with the field investigation, a supplemental laboratory testing program was conducted to determine additional pertinent engineering characteristics of the foundation materials necessary in analyzing the behavior of the proposed building structure. The laboratory testing program included supplementary visual classification and water content determinations on all samples. In addition, selected samples were subjected to Moisture Content Analysis - D4959, and Grain Size Analysis - ASTM designation C-117, C-136. All phases of the laboratory testing program were conducted according to applicable ASTM Specifications and the results of these tests are to be found on the accompanying logs located in the Appendix.

Pavement Design & Analysis File #: 07001-015 Site Information Project Description The purpose of this section is to enumerate details of the proposed structure. The following information was provided by the project engineer. The buildings will be a wood framed, single family residence structures. Daylight basements may be required in sloped areas. Conventional spread footings and slab -on -grade floors are contemplated. Differential settlements are limited to 3/4 inch. A pavement section has not been requested but has been provided within this report. The site of the proposed building addition upon which this soils exploration has been made is located at 30642 28th Ave South in Federal Way. The site topography consists of a slope on the West side of the lots that drops toward the east The total vertical elevation difference is approximately 55 feet over the entire site. The slopes are located in the middle of the site and runs from NW to SE corners. The site drainage consists of surface runoff and natural seepage. The site vegetation is mostly deciduous trees with a few evergreens located on the east side of the lot. Blackberry bushes, neddles, vine maples and Cedar trees are also present. Prior grading has occurred on the east side of the lot near the existing houses. Climate of Area: The climate of the site and surrounding area as taken from the USDA Soil Conservation Service Survey consists of annual precipitation of 35 to 60 inches, most of which is rainfall, between October and May. The mean annual temperature is about 50 degrees F. The frost free season is 150 to 200 days. Geology of Area: (AgB) Alderwood Gravelly sandy loam The geology of the western portion of the site as taken from the USDA Soil Conservation Service Survey consists of Alderwood gravelly sandy loam (AgB). Typical Alderwood soils are moderately well drained, undulating to hilly soils that have dense, very slowly permeable glacial till at a depth of 20 to 40 inches; on uplands and terraces formed under conifers in glacial deposits. This soil is nearly level and undulating, and moderately well drained. Water moves across the substratum in winter. These soils have a slowly permeable glacial till or glacial lake deposits at a depth of 16 to 40 inches and somewhat excessively drained, rolling, deep sandy soils on uplands and terraces. The horizon 0 to 6 inches in depth is usually dark brown. The soil horizon from 6 to 12 inches is dark brown, grayish brown and dark yellowish brown. The horizon 12 to 40 inches is consolidated and mostly grayish brown mottled with yellowish brown. Some layers in this horizon slake in water. There is a consolidated substratum of till at a depth of 24 to 40 inches. Soils above the substratum are pervious when compacted. The surface layer is 2 to 3 inches thicker than the nearby soils to the south Areas are irregular in shape and slopes range from 0 to 6 percent. Runoff is slow and the erosion hazard is slight. The geology of the eastern portion of the site consists of Alderwood gravelly sandy loam (AgC). Typical Alderwood soils are moderately well drained, undulating to hilly soils that have dense, very slowly permeable glacial till at a depth of 20 to 40 inches; on uplands and terraces formed under conifers in glacial deposits. Soil profiles are similar in type except permeability is moderately rapid in the surface layer and subsoil. However, it is very slow within the cemented layer and dense glacial till. A perched water table is as high as 18 to 36 inches at times from January through March. Runoff is slow to medium and erosion hazard is moderate. Description of Foundation Materials: The soil profiles encountered were relatively consistent among most of the pits. It is to be noted that, whereas the test pits were placed and sampled by an experienced technician, it is sometimes difficult to record changes in stratification within narrow limits. In the absence of foreign substances, it is also difficult to distinguish between PO Box 181 Auburn WA. 98071 1 Page 6 of 23 Phone: (206) 786-8645 Fax (253) 833-7316 Email: Jason@jasonengineer.com Jason Engineering & Consulting 3 " f A Business, Inc.

It is recommended that the logs not to be used for estimating quantities due to highly interpretive results. The surface of the proposed construction site is covered with 6 to 12 inches of topsoil that should be removed prior to the start of any construction due to the high compressibility of these soils. Silty sand with gravel was encountered beneath the existing topsoil and extended to depths beyond the scope of this investigation. Lines of demarcation represent the approximate boundary between the soil types, but the transition may be gradual. The top few feet consisted of a brown, silty sand with gravel, medium dense to dense. Below this was a gray to gray - brown gravel with sand and silt This layer was dense to very dense. The layers were fairly consistent with the depths varying between sample pits. In the area of sample pit #6, there was miscellaneous debris, fill, used tires and wood. No trash debris was found in the other sample pits. The total area and quantity of trash found in this area is uncertain and should be carefully observed during excavation to ensure all trash is removed. Geoseismie Setting: Foundation soils on this site are designated a Site Class C, from Table 1615.1.1 per the 2003 International Building Code (I.B.C.). All building structures on this project should be designed per the Code Requirements for such a seismic classification. These types of soils have a shear wave velocity in the range of 1,200 to 2,500 ft/sec The undrained shear strength is typically greater than 2000 psf with blow counts greater than 50 blows per foot The following may be used for the seismic coefficients.

If ground motion lasts for extended amounts of time, the grain to grain contact shifts and the grain structure can collapse. If the water within the soil cannot flow easily between the grain and out of a collapsing area, the water pressure increases. When pore pressures build up within the soil and exceed the effective contact pressure of the soil, the water can push the soil particles apart When the particles lose contact with each other, the soil mass can behave like a liquid. If pore pressures are great enough, water may discharge out of the ground like a geyser leaving characteristic signs, such as sand boils. Liquefaction is generally related to; soil characteristics, water table depths and the degree of seismic activity. The results are lower bearing capacities, increased settlement issues, landslides, and lateral spreading to name a few things. Liquefaction potential for this site is provided within the boundaries of the site. Seismic events which affect land masses on a greater scale are beyond the scope of this report. In our review we found no evidence of liquefaction of the soils in the immediate area from the 1949,1965 and 2001 earthquakes. The site is located within the category III region of the Poverty Bay Auburn quadrangle liquefaction susceptibility map (GM43) which has a VERY LOW susceptibility rating for liquefaction It includes all other Pleistocene glacial and non -glacial deposits and the Osceola Mudflow. Additional information on the site has been reviewed on Liquefaction Susceptibility Map provided by the Department of Natural Resources which rates the site as having a VERY LOW susceptibility to liquefaction.

Two requirements must be fulfilled in the design of foundations. First, the load must be less than the ultimate bearing capacity of the foundation soils to maintain stability; and secondly, the differential settlement must not exceed an amount that will produce adverse behavior of the superstructure. The allowable settlement is usually exceeded before bearing capacity considerations become important; thus, the allowable bearing pressure is normally controlled by settlement considerations. Considering the subsurface conditions and the proposed construction, it is recommended that the structure be founded upon conventional spread and continuous wall footing foundations. Settlements should not exceed tolerable limits if the following design and construction recommendations are observed. Foundation Design Recommendations: On the basis of the data obtained from the site and the test results from the various laboratory bests performed, we recommend that the following guidelines be used for the net allowable soils bearing capacity. 18.0 inch min. required for freeze -thaw 18.0 inches min. width Ground Surface Footing Depth: 18 inches Structural Fill Compaction: 95% ner ASTM D1557 r r r r r r r r r r r r�—�r�r�t �l�w:t6��Fcr tj�gr r i Bearing Capacity: 2,000 PSF ate" All footings are to be excavated to and placed on native undisturbed soils (gray gravel with sand and silt) or compacted structural fill. Footings are required to be a minimum of 18 inches below grade for freeze thaw purposes. After excavation, compact any loose surface soils with a jumping jack compactor. These soils shall be confirmed for bearing capacity and verified by the soils engineer after excavation. After excavation, compact the surface with a jumping jack compactor. Confirm compaction of the native soils and that all soft spots have been removed and replaced with suitable fill material and compacted to least 95% of the maximum dry density as determined by ASTM D-1557. i' Continuous wall footings should be a minimum of 18 inches in width and any slab for the proposed building should be suitably reinforced and connected to the footings so as to limit the effects of differential settlement and to provide some degree of uniform settlement ability for the building should the site undergo liquefaction during a major seismic event PO Box 181 Auburn WA. 98071 Phone: (206) 786-8645 Fax: (253) 833-7316 Email: Jason@jasonengineer.com Page 9 of 23 Jason Engineering & Consulting ' Business, Inc.

No trash debris was found in the other sample pits. The total area and quantity of trash found in this area is uncertain. Footing excavation should be carefully observed during excavation on the sloped area to ensure all trash is removed and the native soils are found. /SF The use of on -site soils as structural fill is acceptable. If these soils are to be used for structural fill, laboratory samples will need to be taken for grain size analysis and moisture -density relationships. Structural fill shallbe compacted to at least 95% of maximum density per ASTM D1557 in footing areas. The footings should be proportioned to meet the stated bearing capacity and/or the International Building Code 2003 minimum requirements. Total settlement should be limited to 1 inch total with differential settlement of 3/4 inch Any excessively loose or soft spots or areas that do not meet the compaction requirements that are encountered in the footing subgrade will require over -excavation and backfilling with at least 1 foot of structural fill. In order to minimize the effects of any slight differential movement that may occur due to variations in the characters of the supporting soils and any variations in seasonal moisture contents, it is recommended that all continuous footings be suitably reinforced to make them as rigid as possible. It is recommended that the services of our firm be engaged to test and evaluate the soil conditions during the construction phase of the project. The design values and recommendations made herein are valid only insomuch as they are followed during the construction phase. Additionally, monitoring and testing during the construction phase needs be performed to verify the subgrade conditions and that suitable materials are used and that they are properly placed and compacted. Lateral Earth Pressures: Lateral earth pressures are dependent upon the backfill materials and their configuration and moisture content. Three inch minus sand and gravel mixtures that are free draining are recommended for backfilling walls greater than four feet tall. Below grade retaining was or walls designed for retaining earthen fills on this project may use the following values for design Values were obtained based on a unit weight of 130 pcf, and a phi angle of 34 degrees. Earth Pressure Coefficients Active, Ka: 0.283 At Rest, Ka: 0.441 Passive, Kp: 3.537 Structural Fill: Earth Pressure Active: 37 lbs./ft3 At Rest: 57 lbs./ft3 Passive: 460 lbs./ft3 Coefficient of Friction 0.35 Structural fill should consist of a 3 inch minus select, clean, granular soil with no more than 5% fines (4200). Suitable structural fill should consist of material that meets one of the following specifications, WSDOT Section 9- 03.10 Aggregate for Gravel Base, WSDOT Section 9-03.14(1) Gravel Borrow, WSDOT Section 9-03.14(2) Select Borrow, WSDOT Section 9-03.9(3) Crushed Surfacing (Base Course Specs), WSDOT Section 9-03.9(3) Crushed Surfacing (Top Course Specs), APWA Class A Pit Run, or APWA class B Pit Run Material that does not meet one of the specifications should be submitted with sieve analysis results for approval prior to placement. The fill should be placed in lifts not to exceed 12 inches in loose thickness. Each layer of structural fill should be compacted to a minimum density of 95% of the maximum dry density as determined by ASTM designation D-1557. For structural fill below footings, the area of the compacted backfill must extend outside the perimeter of the foundation for a distance at least equal to the thickness of the fill between the bottom of the foundation and the PO Box 181 Auburn WA. 98071 Page 10 of 23 Phone: (206) 786-8645 Fax (253) 833-7316 Email: Jason@jasonengineer.com - Jason Engineering & Consulting ot Business, Inc.

If it is elected to utilize a compacted backfill for the support of foundations, the subgrade preparation and the placing of the backfill should be monitored continuously by a qualified engineer or his representative so that the work is performed according to these recommendations. Slope Impact Analysis: Sample pits placed near the sloped portion of the site appear to less dense in the upper layers those observed at lower areas farther to the east of the site. It is likely the existing slope was modified, especially in the area of test pits #6 and #7 where debris was found. Footing excavation should be carefully observed during excavation on the sloped area to ensure all trash is removed and the native soils are found. Re -grading of the slopes will be necessary to reach native competent soils for a solid foundation Excavation into the slope may increase the steepness of the existing slope and require houses in this area to be of a daylight basement structure. We do not anticipate that the proposed residential structure and construction of the project will have any off -site impacts. On -site care should be taken during construction to make sure that runoff caused by wet weather is directed away from all open excavations. The site is stable enough to support the proposed residential construction within the recommendations made herein. There were no signs of previous slope instability or failures. Groundwater Control: Groundwater was not encountered when the field exploration was conducted. A seep was noted only in sample pit #1. Groundwater is not expected to cause difficulties during construction of this project It is recommended that runoff caused by wet weather be directed away from all open excavations. The on -site silty soils can be expected to become soft and pump if subjected to excessive traffic after becoming wet during periods of bad weather. This can be avoided by constructing temporary or permanent driveway sections should wet weather be forecast. The on -site drainage (roof drains & catch basins for pavement areas) should be collected and directed away from the property. This can be accomplished by tight -lining the drainage to the approved storm drainage system. Retaining walls should contain at least 12 inches of free draining material behind the wall as well as a 6 inch perforated drainpipe at the bottom of the wall to alleviate any pressure buildup. Connect the drainpipe to the on site storm drainage system. PO Box 181 Auburn WA. 98071 Page 1 i of 23 Phone: (206) 786-8645 Fax (253) $33 7316 Email.

Pavement Design & Analysis File #: 07001-035 Construction Considerations Earthwork: Excessively organic top soils generally undergo high volume changes when subjected to loads. This is detrimental to the behavior of pavements, floor slabs, structural fills and foundations placed upon them. It is recommended that excessively organic top soils be stripped from these areas to depths of 6-12 inches and wasted or stockpiled for later use. Exact depths of stripping should be adjusted in the field to assure that the entire root zone is removed. It is recommended that the final exposed subgrade be inspected by a representative of the soils engineer. This inspection should verify that all organic material has been removed. Any soft spots or deflecting areas should be removed to sound bearing and replaced with structural fill. Once the existing soils are excavated to the design grade, proper control of the subgrade conditions (i.e., moisture content) and the placement & compaction of new fill (if required) should be maintained by a representative of the soils engineer. The recommendations for structural fill presented within this report, can be utilized to minimize the volume changes and differential settlements that are detrimental to the behavior of footings, and floor slabs. Enough density tests should be taken to monitor proper compaction. For structural fill beneath building structures one in -place density test per lift for every 1,000 ftz is recommended. In parking and driveway areas this can be increased to two tests per lift for every 1,000 W. Excavation equipment may disturb the bearing soils and loose pockets can occur at bearing levels that were not disclosed by the test pits. For this reason, it is recommended that the bottoms of the excavations be compacted in - place by vibratory compactors. The upper 12 inches should be recompacted to achieve an in -place density of not less than 95% of the maximum dry density as determined by ASTM D-1557. Excavations: Shallow excavations required for construction of foundations that do not exceed four feet in depth may be constructed with side slopes approaching vertical. Below this depth it is recommended that slopes not exceed one vertical to one horizontal. For deep excavations, the soils present cannot be expected to remain in position. These materials can be expected to fail, and collapse into any excavation thereby undermining the upper soils materials. This is especially true when working at depths near the water table. Proper care must be taken to protect personnel and equipment. Care must be taken so that all excavations made for the foundations are properly backfilled with suitable material compacted according to the procedures outlined in this report. Before the backfill is placed, all water and loose debris should be removed from these excavations. This information is provided for planning purposes. It is our opinion that maintaining safe working conditions is the responsibility of the contractor. Jobsite conditions such as soil moisture content, weather condition, earth movements and equipment type and operation can all affect slope stability. All excavations should be sloped or braced as required by applicable local, state and federal requirements. Floor Slab -On -Grade: Before the placing of concrete floors or pavements on the site, or before any floor supporting fill is placed, the organic, loose or obviously compressive materials must be removed. The subgrade should then be verified by the geotechnical engineer or his representative that all soft or deflecting areas have been removed. Areas of excessive yielding should be excavated and backfilled with structural fill. PO Box 181 Auburn WA. 98071 Page 12 of 23 Phone: (206) 786-8645 Fax.

Pavement Design & Analysis File #: 07001035 Any additional fill used to increase the elevation of the floor slab should meet the requirement for structural fill. Structural fill should be placed in layers of not more than 12 inches in thickness, at moisture contents at or above optimum, and compacted to a minimum density of 95% of the maximum dry density as determined by ASTM designation D-1557. A granular mat should be provided below the floor slabs. This should be a minimum of four inches in thickness and properly compacted. The mat should consist of sand or a sand and gravel mixture with non -plastic fines. All material should pass a 3/4 inch sieve and contain less than 10% passing the #200 sieve. Groundwater can be expected at shallower depths during the winter months. A moisture barrier, such as visqueen or plastic sheeting, may be placed beneath all floor slabs that are within a foot of the water table, as determined during excavation. Erosion Control (typical of most sites) 1. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the owner/ESC supervisor until all construction is approved. 2. The boundaries of the clearing should be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the owner/ESC supervisor for the duration of construction 3. The ESC facilities are to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 4. The ESC facilities shown on this plan are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g., additional sump pumps, relocation of ditches and silt fences, etc.). 5. The ESC facilities shall be inspected daily by the owner/ESC supervisor and maintained to ensure continued proper functioning. 6. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days during the wet season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). 7. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within forty-eight (48) hours following a storm event 8. At no time shall more than one (1) foot of sediment be allowed to accumulate within a catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment -laden water into the downstream system. 9. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 10. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the temporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the permanent facility. 11. Where straw mulch for temporary erosion control is required, it shall be applied at a minimum thickness of 2 to 3 inches. 12. Prior to the beginning of the wet season (Oct. 1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season PO Box 181 Auburn WA. 98071 I Page 13 of 23 Phone: (206) 78643645 Fax (253) 833-7316 Email: Jason@jasonengineer.com Jason - Engineering & ' Consulting Business, Inc. Geotechnical Engineering Retaining Structures Project Management/ Inspection Pavement Design & Analysis Date: 6-20-2007 Project Steel Lake Crest, 30642 28th Ave South, Federal Way File k 07001-035 Pavement Design Recommendations On the basis of the results of laboratory tests and the assumed traffic counts of the proposed project, the pavement profile should consist of the following recommendations: Existing Subgrade: 1) All subgrade preparation work to be performed should be monitored by a representative of our firm. 2) Over -excavate any areas that exhibit pumping of the subgrade soils at least 12 inches (or as directed by a representative from our firm). Replace with gravel base material. If subgrade is saturated or pumping excessively after over -excavating then it may be necessary to place quarry spalls on the subgrade prior to placement of any gravel base material. 3) On the basis of the existing soils type, the onsite conditions, and the anticipated traffic conditions we recommend that the existing subgrade being compacted to 95% of the maximum dry density as determined by ASTM D-1557 (Modified Proctor). 4) Under certain site conditions the existing subgrade can be accepted by proof -rolling the subgrade using a fully loaded dump truck. This procedure (if used) should be witnessed and accepted by a representative of our firm. 5) A geotextile fabric (if used) should be placed upon the approved subgrade to maintain the structural integrity of the pavement profile. The fabric should be a type of fabric specifically made for use in road construction Crushed Surfacing. 1) The layer of crushed surfacing material should consist of 6 inches of WSDOT Section 9-03.9(3) Crushed Surfacing (Base Course Specs) that is placed and compacted to 95% of the maximum dry density as determined by ASTM D-1557 (Modified Proctor). 2) All of the crushed surfacing and Gravel Base material could at the contractor's option consist of WSDOT Section 9-03.9(3) Crushed Surfacing (Top Course Specs) that is placed and compacted to 95% of the maximum dry density as determined by ASTM D-1557 (Modified Proctor). 3) The material should be placed in lifts not to exceed 6 inches, with each lift being compacted and verified. 4) The crushed surfacing material should be placed to provide the proper grade and drainage for the asphalt pavement. Asphalt Concrete Pavement. 1) The asphalt pavement should consist of at least 3.0 inches of WSDOT Class B asphalt that is placed and compacted to at least 91% of the theoretical maximum density as determined by ASTM D-2041(Rice Method). 2) Provide a tack coat on all concrete surfaces that the pavement will be placed against, and for multiple lifts that are not placed within an hour time period. Conclusion All footings are to be placed on native undisturbed soils (gray gravel with sand and silt). The existing slope appears to be manmade in locations and should be excavated to native soils foundation placement. When the plans and specifications are complete, or if significant changes are made in the character or location of the proposed structures, a consultation should be arranged to review them regarding the prevailing soil conditions. Then, it may be necessary to submit supplementary recommendations. While the recommendations made herein are considered sufficient in detail for the construction of the proposed project, there are many alternative methods of construction which are available. We can discuss various other options for construction at your request.

GENERAL PROJECT INFORMATION Project Name: Steel Lake Crest Preliminary Plat Applicants: Steel Lake Plat Group, LLC: Allan Woida, Mike & Cindy Trinidad and Verlin & Linda Elder Project Location: 30642 28th Avenue South, Federal Way, WA 98003 �(S Site Size: 294,910 sq. ft. (6.77 acres). Zoning: RS 7.2 — Single Family High Density Residential FWCP Designation: Single Family, High Density SUMMARY OF PROPOSED AC. . ION AND BACKGROUND Applicants submitted preliminary plat application to develop 28 single family residential lots on four existing lots totaling 6.77 acres. The applicants will be required to construct an 18, 449 stormwater detention pond in the northeast coiner of the plat; a 329 sq. fit. landscaping tract along Military Road;,, ' 0 + " 3,364 sq. ft. and an 868 sq. ft. landscaping buffer along the front of 28 h Avenue, South; and a 3,661 sq. ft. pedestrian pathway to connect to Military Road, S. The applicants propose significant grading on site, 1 thus removing a majority of the vegetation, excluding many significant trees. STAFF EVALUATION OF ENVIRONMENTAL CHECKLIST Following are staff responses to the elements of the environmental checklist (enclosed) indicating whether or not City staff concurs with the applicant's response to the checklist item, or staff clarification or amendment of the response. A. BACKGROUND 1-3. Concur with the checklist 4. First checklist completed 7/11/07, but revised 5/30/08 after reviewed by Public Works and Planning staff. 5-9. Concur with the checklist. 10. Applicant's agent responded that additional government approvals were: final plat approval, right-of-way permit for road improvements, a WSDOT Discharge Permit, a NPDES permit from Dept. of Ecology, and building permits for individual residential structures. The agent did not include potential right-of-way permit -from WSDOT for location of the pond and pedestrian pathway; a Forest P1[aptiee Permit_frorn a# f Natural Resources; and a demolitpionLe nit_to remove the existing structures. B. ENVIRONMENTAL ELEMENTS 1. Earth a.. Concur with the checklist. b. Originally stated slopes were 9%, but after review of topographic information, it was determined that there were some areas where slopes were around 50%, although the applicant stated this was the result of previous on -site grading. c-d. Concur with the checklist. e. Applicant is proposing to do a mass grading of site to even out slopes and fill from previous development on the site. Subdivision code states that grading should be kept to a minimum to allow for grading for placement of infrastructure such as roads and utility lines. Applicant's agent is stating that in order to construct the infrastructure and pond, that the site needs to be severely graded to allow this to happen. Also, a source of fill on proposed Lot 6 identified construction debris was buried on site. Applicant's agent said excavation of all buried rriateriaIs will take place prior to the grading project taking place. Concur with the checklist. h. Do not concur with the checklist. Th erosion control plan needs to be designed and submitted for review and approval as part of preliminary platapproval The installation - and implementation- will-take-pl-aee—during engineering review,,butmust be submitted for preliminary plat approval. Air a-b. Concur with the checklist. C. Do not concur with the checklist. Since this project is proposing to do mass grading and is located between a residential neighborhood and the I-5 corridor, a watering truck should be kept on site during the entire grading process until the site can be stabilized and water applied as needed throughout the day to assure particulate matter does not affect visibility on the highway or impact ambient air quality in the neighborhood. 3. Water a.1 Concur with checklist with the addition that project lies within 200 ft. of Steel Lake, a lights from tht.

The applicant will be required to address school impacts and,ga fees as requested by the school district at final plat stage. 16. Utilities a-b. Concur with the checklist. CONCLUSION The lead agency for this proposal has determined that the proposal for a residential subdivision project does not have probable significant adverse impact on the environment and an Environmental Impact Statement (EIS) is not required under RCW 43.21C.032(2)(c). This decision was made after review of a completed environmental checklist and other information on file with the lead agency. The information is available to the public upon request. The City reserves the right to review any future revisions or alterations to the site or the proposal in order to determine the environmental significance or nonsignificance of the project at that point in time.

The purpose of this analysis is to provide a safe passage for the potential school -age pedestrians from the new development to the schools serving the area. Those schools are Wildwood Elementary School, located at 2405 South 300th Street, Sacajawea Junior High School, located at 1101 South Dash Point Road, and Federal Way High School, located at 30611 16th Avenue South. School bus service is provided to Wildwood Elementary School and Sacajawea Junior High School. The proposed Steel Lake Crest development is within the one mile walking radius of Federal Way High School, and no bus service will be offered. Therefore a safe walking route to Federal Way High School must be developed paying particular attention to already built sidewalks and safety. This letter is thus the developer's written response to satisfy the Federal Way School District's requirement for an analysis of walking paths to schools and bus stops from new subdivisions. In regard to a new development in the Federal Way School District area and the preference of walking paths to both bus stops and schools we have found a safe resolution. Establishing our starting point at 30642 28 h Avenue South, directly in front of the development, we found the path to the bus stop at the corner of 281h Avenue South and South 310 Street for Wildwood Elementary School consisted of an asphalt road and 6 feet of additional asphalt for the shoulder extending from the white barrier line. The area is relatively flat and includes a drainage ditch at the edge of shoulder, which is present on the majority of the walk. This ditch averages '/2 - 11/z ft. deep and is hidden while driveways and side roads cover it. Various plants and fauna are present as well, overhanging the shoulder occasionally, but not likely to cause a problem. Similarly, the other concerned bus stop at 28�h Avenue South and South 311'h Street raZ__rI WED JUL 1 6 20U OW66AWT* � °�A L WAY BUILDING DEPT. Sacajawea Junior High School has similar attributes. The 6 feet of shoulder along the road is still present as well as the drainage ditch of 1 %2 feet deep. On the other hand, when walking towards this bus stop you will encounter fewer branches overhanging the shoulder, but a lot more shrubbery off of it. Concerning a route for students walking to Federal Way High School, we have found that South 312 Street will be a safer route to walk to school then South 304'' Street. When walking past the previous bus stops, south towards S 312ih St, you will notice the same 6 foot asphalt shoulder and the same 1 V2 feet deep drainage ditch as mentioned before. As you encounter the intersection of S 312" St and 28"' Ave S, you will find yourself at the Steel Lake Maintenance Facility, as its driveway is one of the roads of this intersection. This intersection is a 4-way stop, consisting of stop signs in ail directions, with sidewalks located on the southern part of 281h Ave S and one that crosses S 312`r' St, each with a pedestrian warning sign. First, you must cross the entrance of the maintenance facility where there is no crosswalk and then you will find yourself at a 6 inch gutter sidewalk that's 7 feet wide stretching down 28°i Ave S. There you must cross 28`l' Ave S using its associated crosswalk and end up traveling west on S 312"' St. There you will find that the shoulder is now 6 1/2 feet wide from the white gore stripe to the edge of the asphalt paving. There is another 7 %2 feet of gravel and small branches to the left of shoulder before you will encounter a drainage ditch which ranges from 5 in. to 1 i/2 ft. in depth as it makes it's way downhill towards Pacific Highway South. At the Steel Lake Annex entrances, there are stop signs for the vehicular traffic associated to these roads, but no pedestrian crosswalks present as you must cross these to continue your way. Upon reaching the bottom of the hill you will approach a roadside barrier extending approximately 97 feet and constraining shrubbery and fauna which extends about another 200 feet after the barrier. Here the white barrier line turns into reflectors that are placed every 4 %2 feet from each other. At that location a 6 inch high curb with a 12 foot wide sidewalk begins. The sidewalk has placated trees in it every 3-25 ft. along the curb side of it and is 6 feet from the reflector line. Next you will approach the intersection of S 312th St and 23 d Ave S. This is a 3-way intersection, is regulated with traffic lights, crosswalks on all roads and the reflector line stops. There you must cross 2P Ave S and the signal allows a fair amount of time to cross this street (about 10 sec.). This sidewalk consists of plants and trees laid out like the previous one, but they are now spaced every 10-35 ft. There is a fence 2 feet outside of the sidewalk with a rock ledge emerging at the edge of sidewalk raising the fence 3-2 feet as it diminishes upon arriving at the next intersection. The intersection of S 312'h St and 20th Ave S is a 4-way intersection and is regulated with traffic lights, and crosswalks on all roads. This one however comes equipped to help the sight impaired with "beeps" and says what road you are going and which direction. This sidewalk continues the rock ledge for approximately 26 feet and continues with plants and trees in the same manner as the previous sidewalk. Then three, 20 foot long shade awnings have been built on the edge of the side walk. They are connected with a unique ground layout of concrete slabs. You must then cross a back entrance to Wal-mart to which there is a stop sign but no crosswalk and continue on your way towards the intersection with Pacific Highway South. 2 06066_School Analysis.doc This intersection of Pacific Highway South and S 312th Street is very busy. It is a 4-way intersection, is regulated with traffic lights and also comes equipped with helping the sight impaired. You must cross Pacific Highway South, then heading north cross S 312th Street. Here you will find yourself on an 8 ft. wide curbed and guttered sidewalk with a 5 ft. wide planting strip of trees and grass. This continues for approximately 100 feet till you reach a parking lot entrance. There it changes to a 5 feet wide sidewalk stretching for about 110 feet and is roughly 12 feet from the white barrier line. Then, the sidewalk stops and you are 12 feet from the white barrier line right next to immediate parking extending about 70 feet. This then leads to an 8 feet wide curbed and guttered sidewalk with a 5 feet planter strip of ivy which is about 12 feet from the white barrier line and stretches about 100 feet. The sidewalk then stops and you are then left alone with 12 feet to the white barrier line and a gravel area about 70 feet long by 9 feet wide. This leads to a large 50 feet asphalt corner at Pacific Highway South and S 308th Street, the last intersection before the school This intersection is a 4-way, regulated with traffic lights, crosswalks on all roads, but is not equipped with sight impaired equipment. You then cross S 308th St and you will end up on Federal Way High School grounds and there is a concrete pathway leading directly to the school and its entrance. The streets associated with this path have moderate to high density traffic on them, but this section of Pacific Highway South is commonly known as having very high levels. The posted speed limits of 312' Street and 28t1i Avenue are both 35 mph. on Pacific Highway South it is 45 mph. There are no bicycle lanes or any paths to help in safety in this route, any sight obstructions, or any other pedestrian safety features. Res ectiv 1 r ` Brant A. Schweikl, P.E.

The sight distance survey for the proposed plat was conducted on April 13, 2007. The initial survey found that there will be the required AASHTO entering sight distance available for three of the four entering site distance maneuvering conditions from the proposed two residential intersections with 28th Ave South. After considering several options including reducing the speedmon 28t' Ave South limit from 35 mph to 30 mph to bring the left turning movement from the proposed northerly access point into compliance and in lieu of comments from local. citizens over concerns about the excessive speeds along the 28 h Avenue South corridor the City agreed to one of the lesser desired alternatives. This alternative is to remove the northerly street access and reconfigure the preliminary plat with only the one remaining ingress/egress point. This alternative would also require a revised road modification request to allow the "W" Street section for that portion of the internal street where trips for all of the now 28 residential lots combine at the projects one access onto 28`h Avenue South. This revised road modification was discussed and it was agreed that the "W" Street section could be retained for that portion of the access that has all 28 lots contributing to it. It was also agreed that there would be no parking allowed along either side of the street in that portion in deference to the traffic volumes and turning movements associated with ingressing and egressing on and off of 28th Avenue South from the proposed project. The revised road modification will also will also be resubmittal for consideration ESUg y. 0 ®1BUY7 NOV 022.007 1 06066 sight Distance 071102.duc CITY �LFEDERAL VWAYD BUILDING ❑1mP From the initial sight distance survey report the only maneuvering condition that did not meet the required distance was the southbound turning movement from the past proposed northern internal plat road to 281h Avenue South. The line of site was interrupted vertically by the crest of the road profile of 28' Avenue South and fell approximately 40- feet short of meeting the AASHTO entering sight distance threshold. Also the northbound turning movement would have require the selective pruning of low bushes within the area of the public right-of-way to provide full visibility for a portion of the viewing field at the driver sight point at the northern internal road. The regular maintenance by the City road crews or selective pruning of the bushes within the public right-of-way will provide the necessary sight distance to beyond the AASHTO threshold and beyond. See the revised sight distance drawing, SD -I, that reflects the removal of the northerly access from the proposed preliminary plat of Steel Lake Crest. Therefore considering the above lack of compliance with the AASHTO entering site distance standards the project proponents will be proposing to remove the northerly access and provide half street improvements and associated shoulder tapers along our frontage. With the proposed half street improvements there are no associated improvements to any portion of the western half of 28 h Ave South right-of-way. The proposed improvements will retain the existing traveled lane widths for both the north and southbound lanes of 28'h Avenue South and intend to keep the existing gore stripe in place to direct traffic to remain in the existing lane configuration and not utilize the proposed widening as a through lane since the improvements are of such a short length it would require drivers to perform unnecessary lane maneuvers and potentially increase the potential for traffic accidents related to these maneuvers at the high vehicle speeds being reported by City staff along this stretch of 28th Ave South. The proposal would include the removal of the gore stripe at the proposed intersection if it meets with the requirements of the City Traffic Engineer. Since the proposed project generated trips do not warrant a two way left turn lane (TWM, one is not proposed for the frontage along 28th Ave South. It is also our understanding that there are proposed City of Federal Way intersection and signalization improvements that are planned for the 312'h Street and 28`h Avenue South intersection that will most likely require road widening and tapers along the eastern edge of 28a' Avenue South. The design for the proposed intersection improvements were not available for a detailed analysis of the impacts of the proposed improvements and the cumulative affects of both of the improvements along 28'h Avenue South to include pertinent facts or a discussion of that proposed project's relationship to the Steel Lake Crest proposed improvements..

Project: Steel Lake Crest: 07-103897-00-SU, A& Project No.: 06066 RE: Re -Submittal Cover Letter This cover letter has been prepared in response to review comments made by City of Federal Way staff pertaining to the initial preliminary plat submittal for the Steel Lake Crest project. Specifically, this will address comments made in the following letters; 1. Planning Department, Deb Barker, dated November 30, 2007 2. Public Works Dept., (SEPA Review), Sean Wells, dated December 28, 2007 3. Public Works Dept., Sean Wells, dated January 16, 2008 4. Public Works Dept., (Modification Request) Ken Miller, dated April 17, 2008 The following items pertain to the seven numbered comments on Deb Barkers letter dated November 30, 2007: 1. The project is proposing mass grading for the site, with internal grading on some lots. This is based on the topography of the site. The Grading Plan (G-1) has identified those areas on the site where the slopes exceed 15%. Those lots with internal grading, requiring split level or daylight basement type homes, are also listed on the grading plan. 2. The project is proposing to make a fee -in -lieu -of payment for the balance of its open space obligation at the time of final plat. The total on -site project area is 290,434 square feet. The total open space obligation (15%) would be 43,565 square feet. Subtracting out the qualifying open space areas provided (landscape buffer tracts and pedestrian access tract, the individual tract areas are listed on the preliminary plat) yields a balance obligation fee -in -lieu -of payment for 35,343 square feet. 3. The Roper Company has revised their landscape plan to reflect changes made to the plat layout. They have also addressed the issues stated in the letter as well as the enclosed red -lined plan sheet. Their revised landscape plan is included in the re - submittal. LT FW Resubmittal Itr.doc 4. A revised tree retention plan has been prepared by The Roper Company. The revised plan addresses the changes made to the plat layout, provides for additional existing significant trees to be retained, and proposes replacement trees regulated by a lot -by -lot bases. 5. The project contacted WSDOT about the possible installation of a noise barrier along the state right-of-way. Their response was that they would not be adding noise barriers until they study the impacts of constructing additional lanes to I-5 in that vicinity, most likely 5-10 years in the future. Therefore the project proposes to mitigate noise levels at the site by requiring noise abating construction techniques be used on the proposed residences. 6. Lots 1 and 2 are not shared access private driveways. Both individually access directly to the internal Road A with minimum 20 foot frontages. Lot 1 being a panhandle/pipe stem type design. Lots 22 and 23 are also panhandle/pipe stem lots. They will share a private driveway, with each lot providing a private ingress/egress and utilities easement of 10 feet to each other, thereby obtaining the required 20 foot minimum width. 7. Street lights were added to the preliminary plat map. Pedestrian lighting was also added along the pedestrian access corridor to Military Road. The following items pertain to the three numbered comments, in regard to the projects environmental review (SEPA), from Sean Well's letter dated December 28, 2007: 1. The Department of Ecology's NPDES permit was added to the list of government permits required for this proj ect in section A.10 of the SEPA. 2. The Detention/Wetpond Tract was removed from section B.5.d of the SEPA as a possible habitat for some small species of wildlife. 3. The response for item B.14.a of the SEPA was revised to reflect recent changes made to the plat layout regarding vehicular and pedestrian access to the site. The following items pertain to the numerous comments made on Sean Well's letter dated December 28, 2007: Preliminary Plat Review Checklist 1. a. A vicinity map is shown on the drawing. b. The phone number of each parcel owner is given on the drawing. c. The drawing is stamped and signed by a PE, the final plat will be stamped and signed by a PLS. d. All previous subdivision lots are shown as dotted lines on the drawing. The project site has no previous blocks, streets or easements. e. There are no encroachments to the property boundaries. LT FW Resubmittal ]tr.doe f. All proposed easements are shown on the drawing. g. The adjacent properties parcel numbers and boundaries were added to the drawing. h. The internal loop road was labeled Road A. i. The existing 60 foot right-of-way and proposed half street 39 foot right-of-way for 28th Avenue S are shown on the drawing. j. The proposed 9 foot right-of-way dedication to the city is shown on the drawing. Preliminary Plat, Road & Drainage Map 1. Sheet PP-1: a. All required curb ramps will be added to sheet PP-1. b. The project is not proposing to locate a catch basin at the northernmost plat boundary. Due to topographical constraints, placing a catch basin there would require installing a discharge line across 28th Avenue S. The project is proposing to use the existing discharge line located approximate 35 feet south of the northernmost plat boundary and avoid disrupting traffic on 28 Ave S any more than necessary. c. Per the current KCRS manual, catch basin spacing for roads with slopes greater than 3% should not exceed 300 feet. The up hill catch basin and/or break point is less than 300 feet from the proposed catch basin locations, therefore the project does not propose adding additional catch basins at the western approach to the internal intersection. d. Lots 22 and 23 are pipe stem lots. Both lots have a 10 foot wide frontage access to the internal loop Road A. By granting each other 10 foot wide ingress/egress and utilities easements, the required 20 foot access width is achieved. e. Sheet PP-1 has been revised to show the pedestrian access to Military Road S. A modification request was approved for an 8 foot wide path in a 14 foot wide tract in place of the cities required Type ZZ section. f. The location of I-5 was added to Sheet PP-1 using aerial photos from King Counties iMap services. The edge of shoulder, outside lane gore stripe and surface contours are approximated, as getting actual survey data was impractical. g. A downstream flow line was added to Sheet PP-1. h. Right-of-way lines for both sides of 28th Avenue S. and Military Road S. were added to Sheet PP-1. i. Right-of-way lines for both sides of 28th Avenue S. and Military Road S. were added to Sheet PP-1. j. The tapers and gore striping are shown on sheet PP-1. 2. Sheet CH-1: a. The existing storm drainage layer was shut off. b. The note was corrected. c. The lane width dimension was corrected. d. Gore striping widths were removed to eliminate inconsistencies. The note "existing gore stripe to remain except where noted" was added to the section view. e. The section view was changed to depict the 3 foot utility strip being behind the sidewalk. f. The spelling of "entrance" in Note 2 was corrected. LT FW Resubmitial Itr,doc 3. Sheet G-1: a. The grading plan (G-1) was revised to the current plat layout. b. Sheet G-2 was created to provide the road profile and section view of the internal loop Road A. A section view of the modified pedestrian access path is also included. 4. Sheet L1.1: The Roper Company, certified landscape architects, revised their Tree Retention Plan to address the comments made in the review letter. 5. Sheet L1.2: The Roper Company, certified landscape architects, revised their Site Landscape Plan to address the comments made in the review letter. 6. Topographic Survey: Additional research conducted by True North Land Surveying, Inc. on their original topographic survey of the project site, concluded in a revision being issued for the site boundary in the northeast corner of the project. This revision clarified the Military Road and I-5 right-of-way, and added about 2,500 square feet to the projects on -site area. All preliminary plat drawings were updated to include the boundary revisions. Preliminary TIR 1. The TIR format requirements were reviewed, and some additional items were added to the original document. Being that this is a "preliminary" document, extensive format revisions do not seem reasonable at this time. At the time when a final TIR is required, appropriate changes will be made. 2. The Project Overview was revised to reflect the comments made. 3. The statement noted in the comment letter was removed from the Soils Survey section. 4. The Core Requirement #1 section was re -worded to address comments made. 5. A brief summary of the downstream analysis was added to the Core Requirement #2 section. 6. Maps depicting pre and post development for both basins are included in Appendix F. The off site (west to Steel Lake) basin impervious area calculations, and a letter from the City of Federal Way Public Works Department stating that flow control would not be required for this basin have been added to this section. 7. The 25 year flow rates for each basin were shown to be less than the flow capacity of a 12 inch diameter storm pipe at minimum slope. 8. Discussion of the Department of Ecology's NPDES permit was added to the Core LT FW Resubmittalltr.doc Requirement #7 section. Also noted was the required sediment pond and ESC facilities being designed per Appendix D of the KCSWDM. 9. The City of Federal Way bonding requirements for this project were addressed in the Core Requirement #7 section. 10. Basin maps are included in Appendix F. The off -site (west to Steel Lake) basin will create approximately 2,800 square feet of new pollution generating impervious surface (PGIS), well below the 5,000 square foot threshold necessary to require water quality treatment per the 1998 KCSWDM. The project is exempt from providing a facility for this basin, and that statement was added to the Core Requirement #8 section. 11. The noted statement was removed from this section. 12. The Downstream Analysis was amended to comply with the written comments (12a, 12d & 12e). A new downstream basin map was created and included in the report (12b). KCSWDM forms 8A, 8B and 8C were added to the report (12c). The City of Federal Way Surface Water Management Division was contacted regarding storm drainage complaints, their response by Jeff Wolf PE was added to the drainage complaints section of the report (12f). 13. The list of maintenance standards for drainage facilities has been revised to include only items relevant to this project. 14. The City of Federal Way's Information Sheet for Agreement and Performance/ Maintenance Bond was included in Appendix D. 15. Basin maps B-1, B-2 and B-3 were added to Appendix F. 16. The pre and post development site areas are included in Appendix Cy. A copy of Figure 3.2.2.A was added, as well as a printout of the calculated flows from the developed off -site (West to Steel Lake) basin. Survey Map 1. As previously noted under Preliminary Plat, Road & Drainage Map #6, Topographic Survey, True North Land Surveying, Inc. reviewed the information pertaining to the northeast corner of the site and issued a revision to their initial survey map for the projects boundary in that area. All preliminary plat documents affected by this revision have been updated. Title Report A corrected plat certificate has been obtained from Pacific Northwest Title Co. The expense of a full title report was deemed unnecessary once Eileen Forrester PLS, of True North Land Surveying, Inc., examined and researched Title and Deeds as part of her review prior to issuing a survey boundary revision. LT W Resubmittal ItrAoc Geotechnical Report 1. Jason Engineering & Consulting Business, Inc. corrected the test pit surface elevation log numbers in their report. 2. Jason Engineering & Consulting Business, Inc. verified and added a note to their report regarding percent passing of material. The following pertains to the Request for Modification to Pedestrian Connection response letter from Ken Miller dated April 17, 2008: 1. The requested reduction in pedestrian pathway width from 12 feet in a 20 foot wide tract (Type ZZ section), to an 8 foot path width in a 14 foot wide tract was approved. All preliminary plat documents were updated to reflect this decision. If you should have any questions or require additional information please do not hesitate to contact me, Brant A.

During our exploration, nine test pits were advanced and soil samples submitted for laboratory testing from the project site. The data has been carefully analyzed to determine soils bearing capacities and footing embedment depths. The results of the exploration and analysis indicate that conventional spread and continuous wall footings appear to be the most suitable type of foundation for the support of the proposed structures. Some variability was encountered in comparing the soil profiles of the site. The onsite slopes appear to be manmade in parts and should be observed by a geotechnical engineer prior to concrete placement for foundation. Net allowable soil pressures, embedment depth, soil parameters, and total expected settlements have been presented for the site, later in the report. Often, because of design and construction details that occur on a project, questions arise concerning soil conditions.

Pavement Design & Analysis File #: 07001-035 Site Exploration Procedures General Notes: The field exploration to determine the engineering characteristics of the foundation materials included a reconnaissance of the project site, excavating the test pits, performing field penetrometer and vane shear tests and recovering disturbed grab samples. A total of nine test pits were placed on the site. Test pits were advanced to 10 feet below the existing ground surface. Test pits were located by the field crew near as possible to the proposed building location. Schweikl and Associates supplied a site plan to locate the proposed building orientation and position the excavations. The test pits were located by the field technician by means of normal taping and pacing procedures and are presumed to be accurate to within a few feet. After completion, the pits were backfilled with excavated soils and the site cleaned and Ieveled as required. The types of foundation materials encountered in the test pits have been visually classified and described in detail on the togs provided in the Appendix. The results of the field penetrometer and vane shear tests, moisture contents and other laboratory tests are presented on the logs. It is recommended that the logs not to be used for estimating quantities due to highly interpretive results. Drilling & Sampling Procedures: The test pits were performed with a conventional track excavator. Representative samples were obtained from the pits at various soil intervals. The samples obtained by this procedure were classified in the field by a soils technician, identified according to pit number and depth, placed in plastic bags to protect against moisture loss and transported to the laboratory for additional testing. Laboratory Testing Program: Along with the field investigation, a supplemental laboratory testing program was conducted to determine additional pertinent engineering characteristics of the foundation materials necessary in analyzing the behavior of the proposed building structure. The laboratory testing program included supplementary visual classification and water content determinations on all samples. In addition, selected samples were subjected to Moisture Content Analysis - D4959, and Grain Size Analysis - ASTM designation C-117, C-136. All phases of the laboratory testing program were conducted according to applicable ASTM Specifications and the results of these tests are to be found on the accompanying logs located in the Appendix.

Pavement Design & Analysis File #: 07001-035 Site Information Project Description The purpose of this section is to enumerate details of the proposed structure. The following information was provided by the project engineer. The buildings will be a wood framed, single family residence structures. Daylight basements may be required in sloped areas. Conventional spread footings and slab -on -grade floors are contemplated. Differential settlements are limited to V4 inch. A pavernent section has not been requested but has been provided within this report The site of the proposed building addition upon which this soils exploration has been made is located at 30642 28th Ave South in Federal Way. The site topography consists of a slope on the West side of the lots that drops toward the east The total vertical elevation difference is approximately 55 feet over the entire site. The slopes are located in the middle of the site and runs from NW to SE corners. The site drainage consists of surface runoff and natural seepage. The site vegetation is mostly deciduous trees with a few evergreens located on the east side of the lot. Blackberry bushes, neddles, vine maples and Cedar trees are also present. Prior grading has occurred on the east side of the lot near the existing houses. Climate of Area: The climate of the site and surrounding area as taken from the USDA Soil Conservation Service Survey consists of annual precipitation of 35 to 60 inches, most of which is rainfall, between October and May. The mean annual temperature is about 50 degrees F. The frost free season is 150 to 200 days. Geology of Area: (AgB) Alderwood Gravelly sandy loam The geology of the western portion of the site as taken from the USDA Soil Conservation Service Survey consists of Alderwood gravelly sandy loam (AgB). Typical Alderwood soils are moderately well drained, undulating to hilly soils that have dense, very slowly permeable glacial till at a depth of 20 to 40 inches; on uplands and terraces formed under conifers in glacial deposits. This soil is nearly level and undulating, and moderately well drained. Water moves across the substratum in winter. These soils have a slowly permeable glacial till or glacial lake deposits at a depth of 16 to 40 inches and somewhat excessively drained, rolling, deep sandy soils on uplands and terraces. The horizon 0 to 6 inches in depth is usually dark brown. The soil horizon from 6 to 12 inches is dark brown, grayish brown and dark yellowish brown. The horizon 12 to 40 inches is consolidated and mostly grayish brown mottled with yellowish brown. Some layers in this horizon slake in water. There is a consolidated substratum of till at a depth of 24 to 40 inches. Soils above the substratum are pervious when compacted. The surface layer is 2 to 3 inches thicker than the nearby soils to the south Areas are irregular in shape and slopes range from 0 to 6 percent. Runoff is slow and the erosion hazard is slight. The geology of the eastern portion of the site consists of Alderwood gravelly sandy loam (AgC). Typical Alderwood soils are moderately well drained, undulating to hilly soils that have dense, very slowly permeable glacial till at a depth of 20 to 40 inches; on uplands and terraces formed under conifers in glacial deposits. Soil profiles are similar in type except permeability is moderately rapid in the surface layer and subsoil. However, it is very slow within the cemented layer and dense glacial till. A perched water table is as high as 18 to 36 inches at times from January through March. Runoff is slow to medium and erosion hazard is moderate. Description of Foundation Materials: The soil profiles encountered were relatively consistent among most of the pits. It is to be noted that, whereas the test pits were placed and sampled by an experienced technician, it is sometimes difficult to record changes in stratification within narrow limits. In the absence of foreign substances, it is also difficult to distinguish between PO Box 181 Auburn WA. 98071 Page 6 of 23 Phone: (206) 786-8645 Fax: (253) 833-7316 Email: JasonQjasonengineer.com Jason Geotechnical Engineering Date: 6-20-2007 Engineering & Retaining Structures Project Steel Lake Crest, 30642 Consulting Project Management/ Inspection 28th Ave South, Federal Way Business, Inc. Pavement Design & Analysis File #: 07001-035 discolored soils and clean soil fills. It is recommended that the logs not to be used for estimating quantities due to highly interpretive results. The surface of the proposed construction site is covered with 6 to 12 inches of topsoil that should be removed prior to the start of any construction due to the high compressibility of these soils. Silty sand with gravel was encountered beneath the existing topsoil and extended to depths beyond the scope of this investigation. Lines of demarcation represent the approximate boundary between the soil types, but the transition may be gradual. The top few feet consisted of a brown, silty sand with gravel, medium dense to dense. Below this was a gray to gray - brown gravel with sand and silt. This layer was dense to very dense. The layers were fairly consistent with the depths varying between sample pits. In the area of sample pit 46, there was miscellaneous debris, fill, used tires and wood. No trash debris was found in the other sample pits. The total area and quantity of trash found in this area is uncertain and should be carefully observed during excavation to ensure all trash is removed. Geoseismie Setting. Foundation soils on this site are designated a Site Class C, from Table 1615.1.1 per the 2003 International Building Code (I.B.C.). All building structures on this project should be designed per the Code Requirements for such a seismic classification. These types of soils have a shear wave velocity in the range of 1,200 to 2,500 ft/sec. The undrained shear strength is typically greater than 2000 psf with blow counts greater than 50 blows per foot. The following may be used for the seismic coefficients.

If ground motion lasts for extended amounts of time, the grain to grain contact shifts and the grain structure can collapse. If the water within the soil cannot flow easily between the grain and out of a collapsing area, the water pressure increases. When pore pressures build up within the soil and exceed the effective contact pressure of the soil, the water can push the soil particles apart. When the particles lose contact with each other, the soil mass can behave like a liquid. If pore pressures are great enough, water may discharge out of the ground like a geyser leaving characteristic signs, such as sand boils. Liquefaction is generally related to; soil characteristics, water table depths and the degree of seismic activity. The results are lower bearing capacities, increased settlement issues, landslides, and lateral spreading to name a few things. Liquefaction potential for this site is provided within the boundaries of the site. Seismic events which affect land masses on a greater scale are beyond the scope of this report. In our review we found no evidence of liquefaction of the soils in the immediate area from the 1949,1965 and 2001 earthquakes. The site is located within the category III region of the Poverty Bay Auburn quadrangle liquefaction susceptibility map (GM-43) which has a VERY LOW susceptibility rating for liquefaction It includes all other Pleistocene glacial and non -glacial deposits and the Osceola Mudflow. Additional information on the site has been reviewed on Liquefaction Susceptibility Map provided by the Department of Natural Resources which rates the site as having a VERY LOW susceptibility to liquefaction. r EXPLANATION Liquefaction susceptibility: HIGH Liquefaction susceptibility: MODERATE to HIGH Liquefaction susceptibility: MODERATE ❑ Liquefaction susceptibility: LOW to MODFRATE ❑ Liquefaction susceptibility: LOW Liquefaction susceptibility: VERY LOW to LOW ❑ Liquefaction susceptibility: VERY LOX' PO Box 181 Auburn WA. 98071 Page 8 of 23 Phone: (206) 786-8645 Fax: (253) 833-7316 Email: Jason@jasonengineer.com Jason Geotechnical Engineering Date: 6-20-2007 fAEngineering & Retaining Structures Project Steel Lake Crest, 30642 Consulting Project Management/ Inspection 28th Ave South, Federal Way � Business, Inc. Pavement Design & Analysis File #: 07001-035 Foundation Discussion & Recommendations General Notes: Various foundation types have been considered for the support of the proposed building structure. Two requirements must be fulfilled in the design of foundations. First, the load must be less than the ultimate bearing capacity of the foundation soils to maintain stability; and secondly, the differential settlement must not exceed an amount that will produce adverse behavior of the superstructure. The allowable settlement is usually exceeded before bearing capacity considerations become important; thus, the allowable bearing pressure is normally controlled by settlement considerations. Considering the subsurface conditions and the proposed construction, it is recommended that the structure be founded upon conventional spread and continuous wall footing foundations. Settlements should not exceed tolerable limits if the following design and construction recommendations are observed. Foundation Design Recommendations: On the basis of the data obtained from the site and the test results from the various laboratory tests performed, we recommend that the following guidelines be used for the net allowable soils bearing capacity. Ground Surface 18.0 inch min. required for freeze -thaw 18.0 inches min. width Footing Depth: 18 inches Structural Fill Compaction: 95% oer ASTM D1557 /rrrrrrrrrrr- `- /Ni(tt41l(w461AdatKg/ / / Bearing Capacity: 2,000 PSF All footings are to be excavated to and placed on native undisturbed soils (gray gravel with sand and silt) or compacted structural fill. Footings are required to be a minimum of 18 inches below grade for freeze thaw purposes. After excavation, compact any loose surface soils with a jumping jack compactor. These soils shall be confirmed for bearing capacity and verified by the soils engineer after excavation i1' After excavation, compact the surface with a jumping jack compactor. Confirm compaction of the native soils and that all soft spots have been removed and replaced with suitable fill material and compacted to least 95% of the maximum dry density as determined by ASTM D-1557. A' Continuous wall footings should be a minimum of 18 inches in width and any slab for the proposed building should be suitably reinforced and connected to the footings so as to limit the effects of differential settlement and to provide some degree of uniform settlement ability for the building should the site undergo liquefaction during a major seismic event.

Pavement Design & Analysis File #: 07001-035 A' In the area of sample pit #6, there was miscellaneous debris, fill, used tires and wood. No trash debris was found in the other sample pits. The total area and quantity of trash found in this area is uncertain. Footing excavation should be carefully observed during excavation on the sloped area to ensure all trash is removed and the native soils are found. The use of on -site soils as structural fill is acceptable. If these soils are to be used for structural fill, laboratory samples will need to be taken for grain size analysis and moisture -density relationships. Structural fill shall be compacted to at least 95% of maximum density per ASTM D1557 in footing areas. The footings should be proportioned to meet the stated bearing capacity and/or the International Building Code 2003 minimum requirements. Total settlement should be limited to 1 inch total with differential settlement of 3/4 inch. Any excessively loose or soft spots or areas that do not meet the compaction requirements that are encountered in the footing subgrade will require over -excavation and backfilling with at least 1 foot of structural fill. In order to minimize the effects of any slight differential movement that may occur due to variations in the characters of the supporting soils and any variations in seasonal moisture contents, it is recommended that all continuous footings be suitably reinforced to make them as rigid as possible. It is recommended that the services of our firm be engaged to test and evaluate the soil conditions during the construction phase of the project. The design values and recommendations made herein are valid only insomuch as they are followed during the construction phase. Additionally, monitoring and testing during the construction phase needs be performed to verify the subgrade conditions and that suitable materials are used and that they are properly placed and compacted. Lateral Earth Pressures: Lateral earth pressures are dependent upon the backfill materials and their configuration and moisture content. Three inch minus sand and gravel mixtures that are free draining are recommended for backfilling walls greater than four feet tall. Below grade retaining walls or walls designed for retaining earthen fills on this project may use the following values for design Values were obtained based on a unit weight of 130 pcf, and a phi angle of 34 degrees. Earth Pressure Coefficients Active, Ka: 0.283 At Rest, Ko: 0.441 Passive, Kp: 3.537 Structural Fill. Earth Pressure Active: 37 lbs./ft3 At Rest 57 lbs./ft3 Passive: 460 lbs. / W Coefficient of Friction 0.35 Structural fill should consist of a 3 inch minus select, clean, granular soil with no more than 5% fines (4200). Suitable structural fill should consist of material that meets one of the following specifications, WSDOT Section 9- 03.10 Aggregate for Gravel Base, WSDOT Section 9-03.14(1) Gravel Borrow, WSDOT Section 9-03.14(2) Select Borrow, WSDOT Section 9-03.9(3) Crushed Surfacing (Base Course Specs), WSDOT Section 9-03.9(3) Crushed Surfacing (Top Course Specs), APWA Class A Pit Run, or APWA class B Pit Run. Material that does not meet one of the specifications should be submitted with sieve analysis results for approval prior to placement. The fill should be placed in lifts not to exceed 12 inches in loose thickness. Each layer of structural fill should be compacted to a minimum density of 95% of the maximum dry density as determined by ASTM designation D-1557. For structural fill below footings, the area of the compacted backfill must extend outside the perimeter of the foundation for a distance at least equal to the thickness of the fill between the bottom of the foundation and the PO Box 181 Auburn WA. 98071 1 Page 10 of 23 Phone: (206) 786-8645 Fax: (253) 833-7316 Email: Jason@iasonengineer.com j Jason Geotechnical Engineering Date. 6-20-2007 OfAEngineering & Retaining Structures Project Steel Lake Crest, 30642 Consulting Project Management/ Inspection 28th Ave South, Federal Way Business, Inc. Pavement Design & Analysis File #:-07001-035 underlying soils. If it is elected to utilize a compacted backfill for the support of foundations, the subgrade preparation and the placing of the backfill should be monitored continuously by a qualified engineer or his representative so that the work is performed according to these recommendations. Slope Impact Analysis: Sample pits placed near the sloped portion of the site appear to less dense in the upper layers those observed at lower areas farther to the east of the site. It is likely the existing slope was modified, especially in the area of test pits #6 and #7 where debris was found. Footing excavation should be carefully observed during excavation on the sloped area to ensure all trash is removed and the native soils are found. Re -grading of the slopes will be necessary to reach native competent soils for a solid foundation. Excavation into the slope may increase the steepness of the existing slope and require houses in this area to be of a daylight basement structure. We do not anticipate that the proposed residential structure and construction of the project will have any off -site impacts. On -site care should be taken during construction to make sure that runoff caused by wet weather is directed away from all open excavations. The site is stable enough to support the proposed residential construction within the recommendations made herein. There were no signs of previous slope instability or failures. Groundwater Control: Groundwater was not encountered when the field exploration was conducted. A seep was noted only in sample pit #1. Groundwater is not expected to cause difficulties during construction of this project It is recommended that runoff caused by wet weather be directed away from all open excavations. The on -site silty soils can be expected to become soft and pump if subjected to excessive traffic after becoming wet during periods of bad weather. This can be avoided by constructing temporary or permanent driveway sections should wet weather be forecast. The on -site drainage (roof drains & catch basins for pavement areas) should be collected and directed away from the property. This can be accomplished by tight -lining the drainage to the approved storm drainage system. Retaining walls should contain at least 12 inches of free draining material behind the wall as well as a 6 inch perforated drainpipe at the bottom of the wall to alleviate any pressure buildup. Connect the drainpipe to the on site storm drainage system.

Geotechnical Engineering Retaining Structures Project Management/ Inspection Pavement Design & Analysis Construction Considerations Earthwork: Date: 6-20-2007 Proms Steel Lake Crest, 30642 28th Ave South, Federal Way File #: 07001-035 Excessively organic top soils generally undergo high volume changes when subjected to loads. This is detrimental to the behavior of pavements, floor slabs, structural fills and foundations placed upon them. It is recommended that excessively organic top soils be stripped from these areas to depths of 6-12 inches and wasted or stockpiled for later use. Exact depths of stripping should be adjusted in the field to assure that the entire root zone is removed. It is recommended that the final exposed subgrade be inspected by a representative of the soils engineer. This inspection should verify that all organic material has been removed. Any soft spots or deflecting areas should be removed to sound bearing and replaced with structural fill. Once the existing soils are excavated to the design grade, proper control of the subgrade conditions (i.e., moisture content) and the placement & compaction of new fill (if required) should be maintained by a representative of the soils engineer. The recommendations for structural fill presented within this report, can be utilized to minimize the volume changes and differential settlements that are detrimental to the behavior of footings, and floor slabs. Enough density tests should be taken to monitor proper compaction. For structural fill beneath building structures one in -place density test per lift for every 1,000 ftz is recommended. In parking and driveway areas this can be increased to two tests per lift for every 1,000 W. Excavation equipment may disturb the bearing soils and loose pockets can occur at bearing levels that were not disclosed by the test pits. For this reason, it is recommended that the bottoms of the excavations be compacted in - place by vibratory compactors. The upper 12 inches should be recompacted to achieve an in -place density of not less than 95% of the maximum dry density as determined by ASTM D-1557. Excavations: Shallow excavations required for construction of foundations that do not exceed four feet in depth may be constructed with side slopes approaching vertical. Below this depth it is recommended that slopes not exceed one vertical to one horizontal. For deep excavations, the soils present cannot be expected to remain in position. These materials can be expected to fail, and collapse into any excavation thereby undermining the upper soils materials. This is especially true when working at depths near the water table. Proper care must be taken to protect personnel and equipment Care must be taken so that all excavations made for the foundations are properly backfilled with suitable material compacted according to the procedures outlined in this report Before the backfill is placed, all water and loose debris should be removed from these excavations. This information is provided for planning purposes. It is our opinion that maintaining safe working conditions is the responsibility of the contractor. Jobsite conditions such as soil moisture content, weather condition, earth movements and equipment type and operation can all affect slope stability. All excavations should be sloped or braced as required by applicable local, state and federal requirements. Floor Slab -On -Grade: Before the placing of concrete floors or pavements on the site, or before any floor supporting fill is placed, the organic, loose or obviously compressive materials must be removed. The subgrade should then be verified by the geotechnical engineer or his representative that all soft or deflecting areas have been removed. Areas of excessive yielding should be excavated and backfilled with structural fill.

Structural fill should be placed in layers of not more than 12 inches in thickness, at moisture contents at or above optimum, and compacted to a minimum density of 95% of the maximum dry density as determined by ASTM designation D-1557. A granular mat should be provided below the floor slabs. This should be a minimum of four inches in thickness and properly compacted. The mat should consist of sand or a sand and gravel mixture with non -plastic fines. All material should pass a 3/4 inch sieve and contain less than 10% passing the #200 sieve. Groundwater can be expected at shallower depths during the winter months. A moisture barrier, such as visqueen or plastic sheeting, may be placed beneath all floor slabs that are within a foot of the water table, as determined during excavation. Erosion Control (typical of most sites) 1. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the owner/ESC supervisor until all construction is approved. 2. The boundaries of the clearing should be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction_ During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the owner/ESC supervisor for the duration of construction. 3. The ESC facilities are to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 4. The ESC facilities shown on this plan are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g., additional sump pumps, relocation of ditches and silt fences, etc.). 5. The ESC facilities shall be inspected daily by the owner/ESC supervisor and maintained to ensure continued proper functioning. 6. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days during the wet season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). 7. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within forty-eight (48) hours following a storm event. 8. At no time shall more than one (1) foot of sediment be allowed to accumulate within a catch basin All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment laden water into the downstream system. 9. Stabilized construction entrances and roads shall he installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 10. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the temporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the permanent facility. 11. Where straw mulch for temporary erosion control is required, it shall be applied at a minimum thickness of 2 to 3 inches. 12. Prior to the beginning of the wet season (Oct. 1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season PO Box 181 Auburn WA. 98071 Page 13 of 23 Phone: (206) 786-8645 Fax: (253) 833-7316 Email: jason@jasonengineer.com Jason Geotechnical Engineering Date: 6-20-2007 Engineering & Retaining Structures Project: Steel Lake Crest, 30642 Consulting Project Management/ Inspection 28th Ave South, Federal Way Business, Inc. Pavement Design & Analysis File #: 07001-035 Pavement Design Recommendations On the basis of the results of laboratory tests and the assumed traffic counts of the proposed project, the pavement profile should consist of the following recommendations: Existing Subgrade: 1) All subgrade preparation work to be performed should be monitored by a representative of our firm. 2) Over -excavate any areas that exhibit pumping of the subgrade soils at least 12 inches (or as directed by a representative from our firm). Replace with gravel base material. If subgrade is saturated or pumping excessively after over -excavating then it may be necessary to place quarry spalls on the subgrade prior to placement of any gravel base material. 3) On the basis of the existing soils type, the onsite conditions, and the anticipated traffic conditions we recommend that the existing subgrade being compacted to 95% of the maximum dry density as determined by ASTM D-1557 (Modified Proctor). 4) Under certain site conditions the existing subgrade can be accepted by proof -rolling the subgrade using a fully loaded dump truck. This procedure (if used) should be witnessed and accepted by a representative of our firm. 5) A geotextile fabric (if used) should be placed upon the approved subgrade to maintain the structural integrity of the pavement profile. The fabric should be a type of fabric specifically made for use in road'construction Crushed Surfacing: 1) The layer of crushed surfacing material should consist of 6 inches of WSDOT Section 9-03.9(3) Crushed Surfacing (Base Course Specs) that is placed and compacted to 95% of the maximum dry density as determined by ASTM D-1557 (Modified Proctor). 2) All of the crushed surfacing and Gravel Base material could at the contractor's option consist of WSDOT Section 9-03.9(3) Crushed Surfacing (Top Course Specs) that is placed and compacted to 95% of the maximum dry density as determined by ASTM D-1557 (Modified Proctor). 3) The material should be placed in lifts not to exceed 6 inches, with each lift being compacted and verified. 4) The crushed surfacing material should be placed to provide the proper grade and drainage for the asphalt pavement. Asphalt Concrete Pavement: 1) The asphalt pavement should consist of at least 3.0 inches of WSDOT Class B asphalt that is placed and compacted to at least 91 % of the theoretical maximum density as determined by ASTM D-2041 (Rice Method). 2) Provide a tack coat on all concrete surfaces that the pavement will be placed against, and for multiple lifts that are not placed within an hour time period. Conclusion All footings are to be placed on native undisturbed soils (gray gravel with sand and silt). The existing slope appears to be manmade in locations and should be excavated to native soils foundation placement.. When the plans and specifications are complete, or if significant changes are made in the character or location of the proposed structures, a consultation should be arranged to review them regarding the prevailing soil conditions. Then, it may be necessary to submit supplementary recommendations. While the recommendations made herein are considered sufficient in detail for the construction of the proposed project, there are many alternative methods of construction which are available. We can discuss various other options for construction at your request.
