I D. 40818 4k CITY OF 40':t�� Federal Way FILE STATEMENT OF FINDINGS AND CONCLUSIONS FEDERAL WAY TOWNHOMES 2245 South 333'd Street, Federal Way, WA FILE #07-100010-00-UP The following findings support the Director's conditional approval of the construction of nine new townhouse units at 2245 South 333rd Street in Federal Way (Parcel No. 797820-0180). The Federal Way City Code is abbreviated as FWCC. Summary of proposal: Construction of nine townhomes, in three separate buildings. Each building is three stories with garage on first floor with tandem parking for two vehicles in each garage. Two existing houses at the site are to be removed. Private common recreational open space will be provided on site. 1. Zoning, Land Use, and Review Process. The zoning of the subject site is Residential Multi -Family (RM-2400). The zoning chart found in FWCC 22-667 allows multi -family housing, subject to Process II (Site Plan Review). However, because the project is also subject to the State Environmental Policy Act (discussed below), Process III applies instead of Process Il. Process III is an administrative decision by the Director of Community Development Services. The Director's decision can be appealed to the Federal Way Hearing Examiner. Building permits can be issued after Process III approval is granted. FWCC Section 22-667 requires a minimum lot area of 2,400 square feet of lot area per dwelling unit. The proposal meets the minimum lot area requirement as the parcel is approximately 27,748 square feet in size. 2. State Environmental Policy Act (SEPA) [RCW 43.2 LC]. The proposed construction of nine townhomes, replacing two single-family houses, results in a net gain of seven dwelling units. This exceeds the SEPA categorical exemption of up to four dwelling units on the site. Because the current proposal will result in an aggregate total of more than four units on the site, SEPA review was required. The SEPA notice was combined with the Notice of Application. A Final DNS was issued for the proposed action May 11, 2007. There were no appeals of the DNS. 3. Public Notice [FWCC Section 22-392]. An optional "Determination of Nonsignificance" (DNS) was combined with the Notice of Application on February 14, 2007, and mailed to all owners of property located within 300 feet of the site, as well as various agencies. A comment was received by the Puyallup Tribe of Indians, requesting that an archaeologist oversee and evaluate the proposed location and complete a cultural resource report, and report any historical sites to the Tribe immediately. The Federal Way City Code has no provisions for requiring an archeologist. The applicant may contact the Tribe directly to inquire about an archeological analysis of the site. 4. Site Conditions and Surroundings. The site is currently developed with two houses, which will be demolished. The lot is relatively flat. The northern end of the lot borders on South 333`d Street. A private driveway leading south from 333ra Street will be built along the east side of the site. Along this private drive, there will be one driveway to access seven of the townhouses and another driveway to access two of the townhouses. The site is surrounded by RM zoning in all directions. The surrounding sites are developed with either single-family or multi -family units. Interstate-5 is adjacent to the east side of the private driveway. Thompson Park is across the street to the northwest. The Mahan site, adjacent to the west, recently received City approval for construction of four additional dwelling units (eight total units). 5. Zoning Chart [FWCC 22-667]. The proposal has been reviewed and found to meet the requirements of the zoning chart for the purposes of site plan (Process III) review. Final verification of building height and setback (specifically along the east side) is required in conjunction with final review of the building permit applications. Compliance with FWCC Section 22-667 is as follows, and as conditioned herein: Minimum Lot Size: 7,200 square feet minimum. Existing lot complies with this size. Building Setbacks: 20-foot minimum front setback is along the east property line. The building setbacks are measured from the edge of a vehicular access easement, per the FWCC definition of property line front. The proposed structures meet the 20-foot front setback, with the exception of the most southerly building appears to encroach into the proposed additional three-foot access easement along the east side. The 20-foot setback is measured from a vehicular access easement not sidewalk or pedestrian easement, and therefore the applicant should be able to meet the 20-foot minimum setback from the existing 24-foot-wide vehicular access easement. Compliance with this FWCC could be resolved by making the new 3-foot-wide additional easement specifically for sidewalk, not vehicular purposes. The five-foot minimum side and rear building setbacks are met from the north, south and west property lines. Lot Coverage (impervious surface): FWCC Section 22-667 allows 70 percent maximum lot coverage. Site plan sheet 7-1 identifies 16,130 square feet of impervious surface, which represents approximately 58 percent lot coverage, which complies with FWCC. Building Height: FWCC Section 22-667 allows a maximum height of 30 feet above average building elevation to the midpoint of roof. The height shown on the elevation drawings shows a building height exceeding 30 feet (as 30 feet nine inches is shown). The fiuilding height as shown on sheet L-1 is not approved. Although the maximum height is exceeded on the preliminary elevations, the conceptual height of 30 feet nine inches is acceptable for the purposes of site plan (Process III) review. However, the height of 30 feet nine inches for the final building permit cannot be approved administratively. In addition, the preliminary plans do not provide adequate detailed information to determine complete compliance with the 30-foot maximum height standard. As noted on sheet L-1, the project architect acknowledges that the elevations are conceptual, and the building dimensions and details will be provided with the building permit application. The final elevations and site plan must show compliance .with the maximum 30-foot height standard, in compliance with the Average Building Elevation definition in FWCC Section 22-1. Parking: FWCC Section 22-667 requires a minimum of 1.7 spaces per attached or stacked dwelling unit minimum. This standard is met by providing two -tandem parking stall garages in each unit. Some on -street parking is available along South 333d Street. Statement of Findings and Conclusions Page 2 Federal Way Townhomes File #07-100010-00-UP/no.. i-n. 40819 Special Regulations (as listed in the zoning chart): Density. The maximum number of dwelling units permitted on the site is based on the gross land area of the site following any required public dedications. The maximum density for the RM-2400 zone is one dwelling unit per 2,400 square feet of gross lot area following any required dedications. Based on a total lot area of approximately 27,748 square feet, a maximum of eleven units would be permitted, and the proposed total of nine units is consistent with maximum density. Outdoor Play Area. The project must provide common recreational open space on the site in the amount of 400 square feet per dwelling unit. The open space must meet the design and dimensional requirements of the code, be usable for many activities, and at least 10 percent of the open space must be developed with children's play equipment. The open space must be in one or more pieces each having a length and width of at least 25 feet. Through the Community Design Guidelines (below), common recreational open space must be located and arranged so that windows overlook them. The landscape plan shows that the proposal includes approximately 3,650 square feet of common recreational area requirements, and a tot lot and bench seating are part of the proposed action. The recreation area is centrally located on site, with residential units overlooking the area. The proposal meets the outdoor play area requirements. Building FaVade Modulation. No fagade of any structure may exceed 120 ft. in length. hi addition, any fagade of a structure that exceeds fifty feet in length must be modulated. The north and south facades of the proposed four -unit building exceed 50 feet in length, and include modulation features which comply with the intent of the FWCC_ 6. Driveway Setbacks (FWCC 22-1135). The proposal meets the five-foot driveway setback from the property line. 7. Landscaping and Significant Trees [FWCC Chapter 22, Article XVM. The applicant submitted a landscape plan, prepared by a licensed landscape architect. The standard landscape requirements for this use in this zone are as follows: Twenty -foot -wide strip of "Type 1II" landscaping along public rights -of -ways and vehicular access easements apply along the east and north property line abutting right-of-way and vehicular access easements. Along all remaining property lines (south and west side), the project must provide a ten -foot -wide strip of Type III landscaping. Fifteen square feet of interior lot landscaping per parking stall for common parking areas is inapplicable because there is no common outdoor parking area. At least 25 percent of the significant trees on site must be retained, or replacement trees will be required to be provided. Pursuant to FWCC Section 22-1570(f), in a December 28, 2006 letter, the applicant submitted requests for landscape modification to reduce the 20-foot perimeter buffer requirements along the north and east sides of the site, based on the unusual shape and location of the property, adjacent to I-5 and due to the encumbrance of the existing access easement limiting the developable area of the Statement of Findings and Conclusions Page 3 Federal Way Townhomes File #07-100010-00-UP/Doc ID 40819 property. This modification request is approved; as the overall 20-foot width of landscaping is provided along the east side, with approximately 10 feet of the landscaping adjacent to the access easement and the remaining 10 feet provided abutting the building facades, and interspersed with the common recreation open space area. This landscape modification is supported based on FWCC Section 22-1570(d), as the property is somewhat irregular shape, narrowing on one end, and the property is encumbered by a 24-foot-wide vehicular access easement. In addition, the net 20-foot landscape area is largely provided along the east side of the site as a portion of the landscaping is interspersed with the recreation area open space. The second landscape modification request is to reduce the 20-foot requirement along the north property line to approximately 15 feet in width. This modification request is approved; as the overall reduction of approximately 350 square feet (5' X 70') of perimeter landscaping along the north property line is being replaced by implementing approximately 450 square feet (3' X 150') of perimeter landscaping exceeding FWCC standards along the west property line, by implementing 13 feet of perimeter landscape strip width instead of the minimum 10-foot strip. This landscape modification is supported based on FWCC Section 22-1570(f), as the area where the landscaping is reduced along the north property line, is being relocated and/or averaged by placing additional landscaping along the west property line. The significant tree retention/replacement standards of the FWCC are met. The site currently has a total of two significant trees, which are both located in the location of the proposed four -unit building. The preliminary landscape plan includes one four -inch caliper replacement tree, meeting the provisions of FWCC. The landscape plan is approved for the purposes of site plan review. Final review and approval of the landscape plan will occur in conjunction with review of the building permit applications for the proposal. To comply with applicable FWCC landscape standards, the final landscape plan shall be revised to include the following: • All groundcover shall be planted at approximately 18 inches on center throughout all required and averaged/modified landscape areas including between shrubs and trees per FWCC Type III landscape standards. This standard is not met on the existing plan in several areas along the north and east perimeters. • The shrub planting density shall be increased along the north perimeter and along the entire exterior east perimeter (except the east side of the grass recreation area directly east of the tot lot) to meet the Type III requirements, by planting large shrubs at a maximum triangular spacing of five feet on center. • A minimum of two additional trees shall be planted along the north perimeter to meet the Type III landscape standard of trees at approximately 25 feet on center. • The Public Works Department standards for right-of-way landscaping shall be met. Community Design Guideline. Site and architectural design is consistent with FWCC Chapter 22, Article XIX, "Community Design Guidelines." Guidelines applicable to multi -family residential projects are listed in FWCC 22-1638(d)(2) and 22-1638(a)(5) through (a)(17). Key design guidelines applicable to the multi -family project include, but are not limited to, the following: significant tree retention (as noted above); parking location beside or behind buildings that front on streets; breaking Statement of Findings and Conclusions Page 4 Federal Way Townhomes File #07-100010-00-UP/Doc. Ln. 40819 up parking rows of more than 10 stalls; pedestrian walkways; lighting height; principle entry design; recreational space location; private outdoor spaces; roof pitch; garage and carport location; fagade treatment; building design (should include distinct base, middle, and top); and residential design features. Other applicable design guidelines pertain to general site design, pedestrian circulation, miscellaneous site elements, and building design [FWCC 22-1634 & 22-1635]. The proposal is consistent with the Community Design Guidelines based on the following key design elements: Each building provides for pedestrian connection to sidewalks. The proposal meets parking design standards by having all on -site parking in garages. The recreational open space areas are centrally located and integral to the development. Over half the proposed units overlook the main recreational area. The recreation areas are connected to sidewalks. Each unit has its own outdoor spaces. The roof pitch is consistent with residential areas as the pitch is proposed at 9:12. The project design reflects material variations (i.e., fiber cement siding, window trim treatment, shake trim accents, composition roofing, etc.). The building has a distinct base formed by the dark concrete foundation, middle, and top accented by residential features such as contrasting window bays, balconies, trellises, exterior columns, gabled eaves, pitched roofs, etc. Specific project colors for the buildings are not specified, and must be approved in conjunction with the building permit. Colors shall be generally similar and consistent with the neutral colors and variations shown on sheet L-2, unless otherwise approved by the Director of Community Development Services. The north and south facades of the four -unit building are subject to the building fagade and modulation requirements identified in FWCC Section 22-1635(b). The applicant has met the required treatments by providing sufficient modulations along the facades, by providing covered decks and balconies, bay windows, trellis and vertical columns. To assure an aesthetically pleasing appearance to the exterior of the site, any fencing along the east and west side of the site shall not exceed three feet in height. Any fencing along these sides of the site would be in contrast to the Community Design Guidelines. The proposal has been reviewed and found to meet the Community Design Guidelines as noted above. 9. Critical Areas. There are no critical areas such as streams, wetlands, or steep slopes on the site. 10. Garbage and Recycling. As identified in a September 25, 2007 e-mail from the applicant's agent, each new dwelling unit will have their own trash can and recycling bins. Waste Management is the purveyor of garbage and recycling services. Statement of Findings and Conclusions Page 5 Federal Way Townhomes File #07-100010-00-UP/Doc. W. 40819 11. Surface and Stormwater Management. Drainage components shall conform to the 1998 King County Surface Water Design Manual (KCSWDM) and City amendments. The applicant has proposed a combined underground stormwater detention and water quality vault that will discharge runoff from the site at a metered rate into the existing storm system. Level 1 Flow Control and Basic Water Quality treatment are required for the site in accordance with the KCSWDM as adopted by the City. A Technical Information Report (TIR), dated June 22, 2007 was resubmitted, in accordance with the 1998 King County Surface Water Design Manual (KCSWDM). For the purposes of Site Plan Review, the TIR and plans were reviewed and approved by the Development Services Division of the Public Works Department. Final review of the TIR and drainage plans is required in conjunction with the building permit applications. 12. Traffic Mitigation. The applicant submitted a Concurrency application which has been reviewed by the Public Works Department Traffic Division. The staff report for the Concurrency Analysis dated 1/29/07 identifies no mitigation measures are required for this development. The final staff evaluation for the Concurrency application, Federal Way file #07-100013-CN, is hereby incorporated by reference as though set forth in full. 13. Right -of -Way Improvements. A right-of-way modification request decision was issued by the City on February 8, 2007. The right-of-way modification decision requires the following improvements: 24'hAvenue South (Private Street): Corresponds to a City Street Section `W', consisting of a 28-foot paved roadway with curb and gutter, four -foot planter strips with street trees and street lights, five-foot sidewalks, and three-foot utility strips, within a 52-foot right-of-way. Modified as follows by the Public Works Department: Grant one (1) foot of additional easement width to Parcel Number 7978200186, making the total easement width 25 feet. Provide 20 feet of pavement from the curb radius of South 333'd Street to the southern property line. Provide a five -foot -wide sidewalk along the west side of the access road from South 333rd Street to the southern property line. Provide City standard street lights behind the sidewalk in accordance with existing City standards. Provide vertical concrete curb and gutter along the east side of 24'h Avenue South from the centerline intersection of South 333rd Street and the I-5 right-of-way line, south to the southern property line. South 333rd Street shall be developed along the project frontage with the following code required improvements: South 333rd Street is planned as a Type "R" street, consisting of a 40- foot street with curb and gutter, four -foot planter strips with street trees, six-foot sidewalks, and street lights in a 66-foot right-of-way (ROW). Assuming a symmetrical cross section, three-foot ROW dedication and half -street improvements are required and should be measured from the street centerline. 14. Noise Analysis. The subject site is in very close proximity to Interstate-5. A noise analysis was prepared for the application by Geomatrix, dated December 22, 2007, and submitted to the City. The noise analysis concludes the sound levels on the site are in the range of 70 -73 dBa. The noise analysis also concludes that there are construction techniques available to reduce interior noise levels to 45 dBa or less. In order to assure a quality living environment and provide for the public health, safety and welfare of future residents of the site, the buildings on site shall be constructed to achieve interior noise levels of 45 dBa. Future building permits for the site shall provide noise mitigation methods and written verification from a qualified acoustical engineer that the buildings are designed and constructed to achieve a maximum of 45 dBa interior sound levels. Statement of Findings and Conclusions Page 6 Federal Way Townhomes File #07-100010-00-UP/Doc. r.n. 40819 15. Utilities. Lakehaven Utility District (LUD) is the purveyor of both water and sanitary sewer at this site. LUD provided comments, which have been forwarded to the applicant. Water and sewer availability certificates were submitted. No outstanding water or sanitary sewer issues preclude approval of this Process III application. The underlying recorded Short Plat (KCAF 8110190295) document for the property does not appear to contain sufficient language to allow Lakehaven to access the subject and adjacent property to the south for the purpose of O&M of existing water distribution and sanitary sewer facilities. Lakehaven will require the property owner to execute a separate Access Easement document prior to any new service connection activation(s). Lakehaven will require the applicant to provide a stamped/signed/dated legal description of the access easement area, and will then prepare the easement documents and send them to the applicant for owner signature and return to Lakehaven. 16. South King Fire & Rescue. The Fire Marshal's Office has reviewed the plans for the purposes of site plan review and found them to be acceptable. The existing hydrant at the end of the private drive as well as the hydrant on South 333 rd will be adequate since the buildings will have automatic fire sprinklers. 17. Building Permit. The proposal was routed to the Building Official's Office for review, and no issues were identified which would preclude approval of this Process III application. A building permit will be required for each new building. 18. School Mitigation Fee. Per FWCC requirements, a school mitigation fee is required for each dwelling unit, and must be paid prior to issuance of building permits. School mitigation fee schedules are adjusted annually. Based on the findings listed above, and provided all conditions are met, the Director concludes that the proposal meets the following criteria for all Process III applications [FWCC Section 22-395(b)]: It is consistent with the Federal Way Comprehensive Plan. It is consistent with all applicable provisions of the FWCC, Chapter 22, Zoning. It is consistent with the public health, safety, and welfare. The streets and utilities in the area of the subject property are adequate to serve the anticipated demand from the proposal. The proposed access to the subject property is at the optimal location and configuration. These findings shall not waive compliance with future City of Federal Way codes, policies, and standards. The drawings submitted for building permit review will be reviewed for compliance with specific regulations, conditions of approval, and any applicable City requirements.

The City anticipates that a Determination of Nonsignificance (DNS) will be issued for the proposed project. The optional DNS process of WAC 197-11-355 is being used. The proposal may include mitigation measures under applicable codes, and the project review process may incorporate or require mitigation measures regardless of whether an EIS is prepared. A copy of the subsequent threshold determination for the specific proposal may be obtained upon request. (In addition, the lead agency may choose to maintain a general mailing list for threshold determination distribution.) Integrated Comment Period: Consistent with the provisions of WAC 197-11-355, a single integrated comment period will be utilized to obtain comments on the Notice of Application and Optional Environmental Determination. This may be the only opportunity to comment on the environmental impacts of the proposal. Any person may submit written comments on the environmental impacts of the proposal to the Director of Community Development Services by the comment deadline (noted above). Any interested party may appeal the environmental threshold determination. Details of appeal procedures for the requested environmental decision will be included with the written decision. Issuance of Final Environmental Determination: If timely comments do not identify probable significant adverse impacts that were not considered by the Optional Environmental Determination, the DNS will be issued without a second comment period. A copy of the DNS may be obtained upon request. Consistency with Applicable City Plans and Regulations: The project will be reviewed in accordance with Federal Way City Code (Chapter 22, Zoning), the King County Surface Water Design Manual, Federal Way Road Standards/King County Road Standards, and any other applicable regulations. The official project file is available for public review at the Dept. of Community Development Services, 33325 8`" Avenue South. Comments may be mailed to PO Box 9718, Federal Way, WA 98063 or delivered in person.

Please note that Federal Way does not currently have a zero -lot line ordinance, but is working toward one. Sheet L1 shows "property" line on the elevations. For now we will disregard this. The property lines may be established in the future. For questions about the timing of the proposed zero - lot line ordinance, please contact Margaret Clark, Senior Planner, at 253-835-2646. The project is currently proposed as a multi -family, for -rent project. The callout for "property line" has been revised to "unit line" on the revised Drawing L 1 to represent the separation between individual townhouse units. Public Works Development Services Sean Wells, 253-835-2731, sean.wells@cifyoffederalway.com We have reviewed the preliminary analysis and plans and found items that need to be addressed prior to receiving preliminary approval from Development Services. These items are in accordance with Chapters 21 and 22 of the Federal Way City Code and the 1998 King County Surface Water Design Manual, and are as follows: Preliminary Engineering Plans: 1. The City does not want the additional right-of-way shown along 2411 Avenue South. A 3-foot right-of- way dedication is still required along South 333rd Street. Transition the future right-of-way line from South 333rd Street to the existing right-of-way line along 24th Avenue South with a 25-foot radius. The site plan has been revised to omit the right-of-way dedication along the east boundary (at 241h Avenue) with the 3-foot dedication along 333rd maintained as requested. The access drive has been revised to a 20-foot minimum width with a continuous sidewalk on one side to fit the updated site boundaries. 2. Show the additional one -foot easement width required along the existing 24-foot easement. Curve the easement into the future South 333rd Street ROW line with a 25-foot radius (like what would be done assuming it was a property line). The existing 24-foot wide access and utility easement along the eastern property boundary has been updated to a minimum 27-foot width. This new dimension encompasses the proposed pedestrian sidewalk along the westerly edge of the improved private drive with a constant 6 inches of additional clearance. The proposed access and utility easement terminates at the northerly property line with a 25-foot radius as suggested. - 3. Redesign the NE corner to remove the planter strip on the corner. Place the sidewalk against the top - back of curb. The planter has been omitted with the sidewalk now proposed against the back of curb in the vicinity of the northeast property corner at the intersection of 241h and 333rd as requested. RESUBMITTED .JUN 2 2 2007 CITY OF FEDERAL WAY BUILDING DEPT. Federal Way Townhomes on 333rd CPH Project No. 7706002 June 27, 2007 Page 3 of 5 4. Show the existing utilities, and where the points of connection will be. Please note that South 333,d Street was overlaid in 2006, and current city policies regarding pavement cuts will be enforced. The proposed and existing utilities (including points of connection) are shown "screened" on the updated Site Plan and Preliminary Grading and Drainage Plan exhibits included with this re -submittal package. A complete engineering design package has also been submitted to Lakehaven Utility District for review and approval of the utility permits for the project. 5. The two driveways shall be 20-foot minimum width for two-way drive aisles and emergency access. The clear width of the two driveways to the townhouse units has been increased to 20-feet as requested. 6. Show the required off -site approach taper eastbound on South 333,d Street to the proposed road frontage improvements. A 5:7 taper has been provided for the southerly pavement edge at South 333rd Street to transition the existing pavement width to the proposed frontage improvements for the project. 7. Coordinate with WSDOT (Ramin Pazooki, Development Services Manager, 206-440-4710) to provide the City written documentation of WSDOT's direction with respect to the asphalt pavement on limited access right-of-way. Specifically determine if WSDOT is willing to let the asphalt remain in place, or if they want it removed. Note references have been included on the pertinent plan sheets provided with this re -submittal to clarify that no work is proposed within the WSDOT right-of-way. This note also recognizes that WSDOT will need to approve any future proposals to remove the existing pavement and fence associated with the current access drive location on the Interstate No. 5 right-of-way. Our team will contact Mr. Pazooki as suggested during the engineering design and site improvement permit process to determine WSDOT's preference on whether or not the existing pavement should be removed. Documentation of those future communications will be provided to the City as they occur. 8. Show the locations of the proposed street lights and street trees on the site plan. The locations of the proposed street lights and street trees are shown on the updated site plan included with this re -submittal as requested. Preliminary Street Lighting Plan. 9. Relocate Street Light Pole #3 from the corner to a safer location outside of the sight distance areas (either west or south of the currently proposed location, but not within the curb radius.) The street light design has been revised to locate the proposed luminaires for the current site plan — including the relocation of Pole #3 outside of the sight distance area as requested. JUN 2 2 2007 CITY OF FEDERAL WAY BUILDING DEFT. Federal Way Townhomes on 333rd CPH Project No. 7706002 June 27, 2007 Page 4 of 5 Preliminary TIR and Drainage Plans: 10. It appears that sub -basins P01 and P4 are not being treated for water quality with the proposed system design. All new areas of pollution generating impervious surface (PGIS) require water quality treatment unless accounted for as a treatment trade (KCSWDM 1.2.8.2). Please revise the analysis and/or the design of the stormwater system. The hydrologic analysis for the project has been updated in response to the current site plan and revised storm drainage system design. The storm drainage system has been revised (along with their associated drainage sub -basins) to capture additional contributing areas at the South 333rd Street frontage. A treatment trade approach has been implemented to account for the treatment of all new PGIS. This is described further in Section 4 of the updated Preliminary TIR. 1 1. Provide the pre -developed flow rates for the bypass areas. The pre -developed flow rates for the bypass areas are provided in Section 4 of the updated Preliminary TIR for the project. 12. Per KCSWDM 5.3.3.1 "Setbacks" the setback from the adjacent builds to the vault shall be 10 feet. Because this will be a privately owned and maintained vault, building foundations may serve as one or more of the vault walls. Please revise the vault location and/or design. The locations of the buildings adjacent to the storm drainage vault have been adjusted to provide the 10- foot minimum clearance requested. 13. Reprint the conveyance calculation spreadsheet to a larger, legible font for review. The conveyance calculations provided in Appendix A have been re -printed at a larger, more legible scale as requested. Public Works Traffic Division Soma Chattopadhyay, 253-835-2745, soma.chattopadhyay For your information only, 15.f of the SEPA checklist should have been 14 new peak hour trips (not 9) per the Institute of Traffic Engineers Manual 7fh Edition. Also, regarding 15.g, concurrency fees towards the Transportation Improvement Plan projects will be $26,01 1. The applicant understands this clarification regarding trip generation and that the $26,0 7 1 concurrency fee will be payable at the time of building permit issuance. South King Fire & Rescue Chris Ingham, 253-946-7244, chris.ingham@southkingfire.org The applicant must add a hydrant to the east side of the property at Building #3. The existing hydrant on 215} Avenue South is not accessible for this project. Please revise the plans accordingly. A hydrant has been added at the southerly limit of the improved private drive in the vi�kj§6f auddin ED #3 as requested. JUN 2 2 2007 CITY OF FEDERAL WAY BUILDING DEPT.

More specifically, the following is a description of the location and proposed encroachments into the building setback/landscape buffer at the frontage along 333rd: The northerly -most building on the project site is proposed to have its structure's northerly elevation located at the 20-foot setback line. Uncovered decks are proposed at the "front" of these buildings, and these decks would extend into the building setback/landscape buffer area along the southern edge of 333rd. The orientation of the uncovered decks shown in Exhibit L2, Conceptual Building Renderings has been reversed for this project. Exhibit L1, Building Elevations/Design Intent shows the proposed orientation of the decks on the "front" of the units (i.e., opposite the garage access elevation, which is different from what is illustrated in Exhibit L2). The necessary and proposed encroachment of the uncovered decks has been shown in all of the site plans for Nc, T the project to -date, and this was suggested in my December 28, 2006 letter to Greg Fewins regarding _-))A development standards modifications which was submitted with our initial application. All structural elements of the residential structures (i.e., foundations and exterior walls) are proposed to be located outside of the building setback areas. There have been no comments related to this encroachment of the uncovered decks to -date. All City comments to -date have been responded to with our previous (and most current) re -submittal. I would appreciate it if you would contact me directly to discuss this item further and to update me on the City's anticipated schedule for approval of the Use Process III permit.

As we prepare for that re -submittal and subsequent site plan approvals, I wanted to confirm what permits we would be receiving and what additional permits would be required to complete the project. Our Master Use Application as submitted sought SEPA, Use Process III, and Land Modification review and approvals. The Owner's interest at the time of application was to get site improvement approvals so they could start on site work as the building architecture, plans, and associated permits were in process. As I understand it, our pending approval (which includes Land Modification) will allow the Owner to clear, grade, and install the drainage improvements as shown on the Use Process III plans. The structures (including storm vault) would be. separate building permits which are planned to be submitted after we have Site Plan approval. I also understand that the Water and Sewer improvements are reviewed and permitted separately through Lakehaven Utility District (application, review, and permit approvals pending). I would appreciate it if you could confirm that my understanding of the required permits for the project and planned work is as I have described.

As you know, a combined Notice of Application/Optional Determination of Nonsignificance was issued, followed by the issuance of a Final DNS. There was no appeal of the DNS. Please address the following technical comments. The following reviewers have been assigned to your project. For specific questions, you may contact the appropriate reviewer. I have prepared a draft staff report, which I will finish once all of the technical issues have been addressed. Community Development Services Andy Bergsagel, 253-835-2644, andy.bergsagel@cityoffederalway_com Please dimension the height measurement (of 30 feet to midpoint of gable) on drawing L1. 2. What is the impervious surface coverage percentage? I can red -line this lot coverage and height information on the plans, once I get your response letter; alternatively, you may resubmit revised plan sheets. Please note that Federal Way does not currently have a zero -lot line ordinance, but is working toward one_ Sheet Ll shows "property" line on the elevations. For now we will disregard this. The property lines may be established in the future. For questions about the timing of the proposed zero -lot line ordinance, please contact Margaret Clark, Senior Planner, at 253-835-2646. Public Works Development Services Sean Wells, 253-835-2731, sean.wells@cityoffederalway.com We have reviewed the preliminary analysis and plans and found items that need to be addressed prior to receiving preliminary approval from Development Services. These items are in accordance with Chapters 21 and 22 of the Federal Way City Code and the 1998 King County Surface Water Design Manual, and are as follows: c. Mr. ]-tough May 15; 2007 Pane 2 Preliminary Engineering Plans: 1. The City does not want the additional right-of-way shown along 241h Avenue South. A three-foot right-of-way dedication is still required along South 333`d Street. Transition the future right-of-way line from South 333`d Street to the existing right-of-way line along 24`h Avenue South with a 25-foot radius. 2. Show the additional one -foot easement width required along the existing 24-foot easement. Curve the easement into the future South 333`d Street ROW line with a 25-foot radius (like what would be done assuming it was a property line). 3. Redesign the NE corner to remove the planter strip on the corner. Place the sidewalk against the top - back of curb. 4. Show the existing utilities, and where the points of connection will be. Please note that South 333`d Street was overlaid in 2006, and current city policies regarding pavement cuts will be enforced. 5. The two driveways shall be 20-foot minimum width for two-way drive aisles and emergency access. 6. Show the required off -site approach taper eastbound on South 333`d Street to the proposed road frontage improvements. 7. Coordinate with WSDOT (gamin Pazooki, Development Services Manager, 206-440-4710) to provide the City written documentation of WSDOT's direction with respect to the asphalt pavement on limited access right-of-way. Specifically determine if WSDOT is willing to let the asphalt remain in place, or if they want it removed. 8. Show the locations of the proposed street lights and street trees on the site plan. Preliminary Street Lighting Plan: 9. Relocate Street Light Pole #3 from the corner to a safer location outside of the sight distance areas (either west or south of the currently proposed location, but not within the curb radius.) Preliminary TIR and Drainage Plans: 10. It appears that sub -basins POI and P4 are not being treated for water quality with the proposed system design. All new areas of pollution generating impervious surface (PGIS) require water quality treatment unless accounted for as a treatment trade (KCSWDM 1.2.8.2). Please revise the analysis and/or the design of the stormwater system. 11. Provide the pre -developed flow rates for the bypass areas. 12. Per KCSWDM 5.3.3.1 "Setbacks." the setback from the adjacent builds to the vault shall be 10 feet. Because this will be a privately owned and maintained vault, building foundations may serve as one or more of the vault walls. Please revise the vault location and/or design. 13. Reprint the conveyance calculation spreadsheet to a larger, legible font for review. Public Works Traffic Division Soma Chattopadhyay, 253-835-2745, soma.chattopadhyay For your information only, 151 of the SEPA checklist should have been 14 new peak hour trips (not 9) per the Institute of Traffic Engineers Manual 7`h Edition. Also, regarding 15.g, concurrency fees towards the Transportation Improvement Plan projects will be $26,011. 07-1 ON 10 Doc I D. 39591 Mr. Hough May 15, 2007 Page 3 South King Fire & Rescue Chris Ingham, 253-946-7244, chris.ingham@southkingfire.org The applicant must add a hydrant to the east side of the property at Building #3. The existing hydrant on 21s1 Avenue South is not accessible for this project. Please revise the plans accordingly. Lakehaven Utility District Brian Asbury, 253-946-5407, basbury@lakehaven.org The applicant has not completed and submitted to Lakehaven Utility District all applications necessary to be able to determine the requirements for connection to Lakehaven's water and/or sewer systems to serve the subject property. The applicant will need to submit one or more of the following applications to Lakehaven to formally commence the water and/or sewer plan review process: Developer Extension Pre - Design or Developer Extension Agreement. Lakehaven continues to emphasize that the owner/applicant should apply separately to Lakehaven early in the pre-design/planning phase to avoid delays. CLOSING Please submit four copies of the revised slip sheets (collated). Please use the enclosed resubmittal form. For non -planning questions, please contact the reviewers listed above. For planning or general questions you may contact me at 253-835-2644 or andy.bergsagel@cityoffederalway.com.

The subject property is located within the Usual and Accustomed area of our people. The term "Usual and Accustomed Areas" comes from the treaties that the tribes in this area signed with the federal government. Tribes reserved right to hunt, fish and gather in our "usual and accustomed grounds and stations." These U&A areas have been adjudicated by the federal courts. As with all of these areas they are significant areas to our Tribe. The project location is in very close proximity to several areas that have potential for possible archaeological discoveries. At this time, please recognize that historic sites may be exposed when such projects are undertaken. We recommend that you hire an archaeologist to oversee and evaluate the proposed location of your project and complete a cultural resource report. Any exposure of historical sites will need to be reported to my office immediately. The comments contained within this letter apply to cultural and historic resources exclusively. The Tribe encourages your agency to contact the Tribe's Natural Resources, Land Use, or other applicable departments and solicit those departments' input on your project. Other Tribal departments may have objections, concerns or input into your proposal above and beyond comments contained within this letter. Thank you for your prompt response in this matter.

We have reviewed the preliminary analysis and plans and found items that need to be addressed prior to receiving preliminary approval from Development Services. These items are in accordance with Chapters 21 and 22 of the Federal Way City Code and the 1998 King County Surface Water Design Manual, and are as follows: Preliminary Engineering Plans: 1. The City does not want the additional right-of-way shown along 24th Ave. S. A 3-foot right-of-way dedication is still required along S. 333rd St. Transition the future right-of-way line from S. 333`d St. to the existing right-of-way line along 240 Ave. S. with a 25-foot radius. 2. Show the additional 1-foot easement width required along the existing 24-foot easement. Curve the easement into the future S. 333'd St. ROW line with a 25-foot radius (Like what would be done assuming it was a property line). 3. Redesign the NE corner to remove the planter strip on the corner. Place the sidewalk against the top -back of curb. 4. Show the existing utilities, and where the points of connection will be. Please note that S. 333'd St. was overlaid in 2006, and current city policies regarding pavement cuts will be enforced. S. The two driveways shall be 20' minimum width for 2-way drive aisles and emergency access. 6. Show the required off -site approach taper eastbound on S. 333rd St. to the proposed road frontage improvements. 7. Coordinate with WSDOT (Ramin Pazooki, Development Services Manager, 206.440.4710) to provide the City'written documentation of WSDOT's direction with respect to the asphalt pavement on limited access right-of-way. Specifically determine if WSDOT is willing to let the asphalt remain in place, or if they want it removed. 8. Show the locations of the proposed street lights and street trees on the site plan. Preliminary Street Lighting Plan: 1. Relocate Street Light Pole #3 from the corner to a safer location outside of the sight distance areas (either west or south of the currently proposed location, but not within the curb radius.) Preliminary TIR and Drainage Plans 1. It appears that sub -basins P01 and P4 are not being treated for water quality with the proposed system design. All new areas of pollution generating impervious surface (PGIS) require water quality treatment unless accounted for as a treatment trade (KCSWDM 1.2.8.2). Please revise the analysis and/or the design of the stormwater system. 2. Provide the pre -developed flow rates for the bypass areas. 3. Per KCSWDM 5.3.3.1 "Setbacks", the setback from the adjacent builds to the vault shall be 10 feet. Because this will be a privately owned and maintained vault, building foundations may serve as one or more of the vault walls. Please revise the vault location and/or design. 4. Reprint the conveyance calculation spreadsheet to a larger, legible font for review.

Subject: Sound Level Report for the Federal Way Townhomes Development Federal Way, Washington Dear Mr. Roberts: Geomatrix Consultants, Inc. (Geomatrix) has completed a noise analysis for the proposed Federal Way Townhomes development in Federal Way, Washington. Because the proposed townhomes would be constructed on a site adjacent to Interstate 5 (I-5), and traffic noise from I- 5 dominates the acoustic environment on this site, a noise study was requested by the City of Federal Way. The methods and results of the measurement and analysis are discussed below. Noise Level Limits The City of Federal Way has adopted the sound level limits and regulations established in Chapter 173-60 of the Washington Administrative Code (WAC 173-60). The noise limits identified in WAC 173-60 are typically applied to individual source properties of noise (e.g., specific industrial or commercial developments) and are applied at exterior locations. Noise from vehicles traveling on public roadways or highways is exempt from these noise limits. The City of Federal Way has not specifically adopted noise standards for new residential development being constructed in areas with high levels of existing noise, including noise emitted by traffic on a public highway (such as the case here). However, the City has indicated that the noise study for this development should measure the existing sound levels on the project site and identify likely interior sound levels for the residential units. The City identified an "acceptable" interior noise limit of 45 dBA Ldn.1z 1 Personal communication with Greg Fewins, Deputy Director of Community Development Services for the City of Federal Way, August 2006. 2 The Leq is the level of a constant sound that has the same sound energy as the actual fluctuating sound. It can be considered an energy -average sound level. The Ldn is a 24-hour Leq with a 10 decibel penalty added to sound levels that occur between 10 p.m. and 7 am. in consideration of potential disturbance of people trying to sleep. 19203 36th Avenue West, Suite 101 Tel 425.921.4000 www_seomatrix.com Lynnwood, Washing on 98036-5772 Fax 425.921.4040 Mr. Scott Roberts Federal Way Townhomes Noise Study December 22, 2006 Page 2 Existing Sound Levels To document the existing sound levels on the site, Geomatrix measured sound levels at two on - site locations representing the nearest location of the proposed townhomes to I-5. The first measurement, SLMI, was a 24-hour measurement from December 5 to 6, 2006 with the microphone positioned 5 feet above the ground. Sound levels were recorded in hourly intervals over the 24=hour period. The second measurement, SLM2, was near SLMI but was elevated 16 feet above the ground and was taken simultaneously during one hour of the 24-hour measurement at SLMI. SLM2 was taken to determine the difference in sound levels at an elevated height, compared to the sound levels at 5 feet above the ground, where the elevated height represents the upper floors of the proposed townhomes. Both sound level measurements were taken using Larson Davis 820 (Type 1) sound level meters. For both measurements, the meters and microphones had been factory calibrated and certified within the past twelve months, and the meters were field calibrated immediately prior to the measurements. The 24-hour measurement was not attended, except during setup and retrieval of the units and during the 1-hour elevated measurement, during which contributing sound sources were noted. The measured sound levels at each location are summarized in Table 1. Details of the 24-hour measurement at SLMI are shown in a table attached to the end of this letter. Table 1. Range of Measured Hourly Sound Levels (dBA) Receptor Time Leq Lmax Ldn SLMI Day 63-68 71-88 70 Night 59-66 70-84 1— 2 p.m. 68 74 SLM2 1— 2 p.m 1 71 77 73a a The Ldn at the elevated location was calculated based on the difference between the measured hourly Leqs between 1 and 2 p.m. at SLMI (5 feet above the ground) and at SLM2 (16 feet above ground). The difference in hourly Leqs was then applied to the measured Ldn at SLMI to calculate the Ldn at SLM2. Methods and Results of Analysis The Ldn at SLM2 was used for this analysis because the sensitive interior living spaces are proposed to be located on the upper floors of each townhome. The calculated Ldn at SLM2 (Table 1) was adjusted using standard distance attenuation calculations for a line source (i.e., 3 dBA reduction for every doubling of distance) to represent the different townhomes proposed for P:\FedWayHomes_13014\docs'Fcd 1E'ayTownfiomes_FnalNoiseReport.doc Mr. Scott Roberts Federal Way Townhomes Noise Study December 22, 2006 Page 3 this development. The Ldn at SLMI is representative of the ground floor use, the garage, which is not a sensitive space and is not considered further in this analysis. The estimated sound levels for each townhome are displayed in Table 2. Table 2.

Interior Noise Reduction To meet the interior noise level goal of 45 dBA Ldn suggested by Greg Fewins at the City of Federal Way, construction techniques and materials for each of the residential units would need to achieve an exterior to interior sound level reduction of 27-28 dBA. Mr. Jim Cornwell of the Port of Seattle Noise Remedy Program reported to Geomatrix personnel that a good working range of noise reduction provided by residential structures is 15 to 33 dBA. This range is based on direct measurements of jet aircraft noise in the vicinity of Sea-Tac International Airport, where the affected residential structures are about 20 years old (i.e., typically 2 x 4 wall construction). Mr: Cornwell said to expect a minimum of a 15-dBA reduction even with "paper thin" walls and further estimated that the vast majority of existing residential structures provide reductions in the range of 22-30 dBA as long as windows and doors are not used for ventilation. P.\FedW ayHomes_130l4\docs\Fe6W.iY I-n wn1, omes_Fi nalNoiseReporLdoc Mr. Scott Roberts Federal Way Townhomes Noise Study December 22, 2006 Page 4 Therefore, using careful construction techniques designed to ensure good thermal insulation could provide 27-28 dBA of noise reduction inside the residence, resulting in interior Ldos (from traffic noise) of 45 dBA or less at all residences. These construction techniques would include minimizing openings to the outside; ensuring that gaps around doors, vents, and windows are caulked and sealed; and constructing exterior walls with 2 x 6 wall construction with extra sheeting to increase mass and/or the use of "sound deadening board" on the interior wall and filling the wall cavity with uncompressed insulation material. Windows and doors are often sources of air and noise leaks, so special attention should be paid to ensure that adequate gasket materials (e.g., compression gaskets) are used. Also, selecting windows with higher sound reduction abilities (i.e., 30 dBA or greater for traffic noise) and using smaller window openings on the sides of the houses facing the freeway would help to ensure that interior noise reductions of 28 dBA are met. In addition to careful attention to the exterior wall construction, windows, and doors, active ventilation systems will be required to distribute air in these residences, since the noise mitigation techniques identified above would need to ensure that the residences are air -tight. Once a window were opened, only a 12-15 dBA reduction in exterior noise levels would be expected, resulting in potential interior sound levels of up to 57-61 dBA Lan. This level far exceeds levels considered acceptable for interior use, particularly for bedrooms. Any air inlet openings required for an active ventilation system should be placed on exterior walls or rooftops opposite the freeway to ensure that they do not transmit freeway noise to the interior of the residence. Conclusion With careful construction techniques and active ventilation systems that do not require open windows or doors, the proposed Federal Way Townhomes development would likely meet Federal Way's goal for interior sound levels of 45-dBA Ldn in new residential developments.

The following is a summary of the key elements and/or special considerations for the project: Existing Residences and Proposed Project There are two residential structures currently located on the property. These structures will be removed with the proposed project. Site improvements include 9 new residential townhome units, supporting private access drives, on -site common open spaces, landscaping and other private amenities. Site Access South 333rd Street fronts the northerly boundary of the property and an existing paved private road is located along the easterly property edge through a portion of the 241h Avenue South and Interstate No. 5 right-of-ways, and an existing access easement located on the site. The project proposes to widen South 333rd Street to City standards along the frontage of the subject property. 241h Avenue South would be widened to a full __-foot wide pavement section with curb and gutter both sides and a pedestrian sidewalk along the easterly property boundary. The 24th Avenue improvement would continue south from South 333rd Street to the point where the property adjoins the right-of-way of Interstate No. 5. The existing paved private drive along the easterly property boundary is to be improved to a minimum 20-foot pavement width with curb, gutter, and a sidewalk along its westerly edge for the remaining length of the property to connect the existing driveway for the adjacent property to the south. The existing South 333rd Street and 24th Avenue South right-of-ways are proposed to be widened to accommodate the improved pavement sections for the public portions of the roadways. The private road improvements would be contained within the existing 24-foot wide access and utility easement along the easterly property boundary. A public pedestrian and utility easement would contain any portions of the proposed sidewalk improvements along the eastern edge of the property that are located outside of the final right-of-way or existing 24-foot easement widths. Vehicular access to the project site is proposed by two on -site driveways that connect to the improved 24th Avenue South and private road. The dimensions of these private on -site driveways are in accordance with City of Federal Way standards and adequate for vehicular turning movements into and out of the proposed townhome units as well as emergency vehicle access. Surface Water Provisions Storm drainage controls (detention and water quality facilities) for this project are proposed in general accordance with current City of Federal Way standards. An on -site, underground vault is proposed to detain storm drainage runoff rates and treat storm water volumes discharged from the improved property. Current City of Federal Way surface water design standards require that above ground features be used for storm water controls for residential and multi -family projects unless certain site constraints limit the practicality of above -grade facilities. Such site limitations exist for the subject property and consideration of these existing site constraints are requested to allow for the proposed underground vault facilities. Federal Way Townhomes CPH Project No. 7706002 December 28, 2006 Page 3 of 3 Currently, stormwater runoff from the property is conveyed southwesterly as sheet flow. The nearest public drainage system is located approximately 200 feet west of the project site. This off - site system conveys stream and surface water flows southerly in a closed underground pipe under South 333rd Street. The on -site drainage system for this project will include flow control, water quality treatment, and conveyance facilities that ultimately discharge to this off -site pipe system via a connection to an existing storm drainage catch basin at the south edge of South 333rd Street. Sensitive Areas Protection There are no known or obvious indicators of environmentally sensitive areas on -site. Temporary erosion and sediment control features will be implemented during construction of the project and permanent stormwater treatment facilities will be incorporated into the site design to provide adequate protection of off-site/downstream sensitive areas.

Federal Way Townhomes, CPH No. 1706002 Request for Consideration of Special Site Considerations and Development Standards Modifications Dear Mr. Fewins, This letter is provided in support of the Use Process III and Land Use Modification permits for the Federal Way Townhome project to request special consideration and variances to certain specific City of Federal Way development standards. The subject property is approximately 0.6 acres located along the south frontage of South 333rd Street in the City of Federal Way (KC Parcel No. 7978200180). The project proposes to improve the site to support 9 new attached residential townhome units in accordance with the current RM-2400 zoning and City of Federal Way development standards. There are existing site constraints that make conformance with a limited number of City land use and development standards impractical and/or would unnecessarily adversely impact the residential density and community features of the property. These include topographic conditions, the shape and proximity of the site to adjacent right-of-ways and private properties, and a significant access/utility easement that encumbers the entire easterly portion of the property. The current site plan for the project proposes site improvement alternatives in response to these challenges that provide equivalent public benefits. Perimeter Landscape Buffer Width Modifications Current Federal Way City Code (FWCC) 22-1566(c)(3) provides specific Type III perimeter landscape buffer widths for the project site. The standard perimeter landscape area for this RM-2400 property typically requires a continuous 10-foot width along the west and south perimeters where multi -family residences and like zoning exist. Current code also requires a 20-foot wide perimeter landscape buffer along the north and eastern boundaries of the property that are adjacent to public right-of-way and/or the existing private access easement. However, these typical buffer depths are in conflict with other important land use criteria and community development standards including the requirement for on -site common open space, surface water controls, pedestrian connectivity, and overall residential density. The unusual shape and location of the site adjacent to Intestate No. 5 (1-5) along with encumbrance of the property by the existing access/utility easement limit the amount of property available for residential structures and community features. The residential density of the proposed project is already 2 residential units (approximately 82 %) less than the allowable 11 units prescribed by the current zoning. Applying the typical landscape buffer widths would further reduce the residential density by an additional 2 units once the necessary access and pedestrian improvements are considered, which would be an approximate 36% reduction in the planned residential density for the property. 733 71h Avenue, Suite 100 • Kirkland, WA 98033 • Phone: (425) 285-2390 - Fax: (425) 285-2389 www.cphconsultants.com Federal Way Townhomes CPH Project No. 1706002 December 28, 2006 Page 2 of 3 Application of the standard FWCC provisions would result in a total perimeter landscape buffer area of 8,640 square feet. The project proposes to reduce the landscape buffer width at limited areas along the north, northwest, and southeastern boundaries to approximately 7,440 square feet (a 15% reduction) in accordance with the modification criteria provided by FWCC 22-1570. More specifically, the proposed modification would not reduce the width below 50% of the required standard per FWCC 22-1750(e). The minimum width of the proposed perimeter landscape buffer is 4 feet at a point along the southeastern property boundary adjacent to the improved private drive (not including the width of the pedestrian walkway). The proposed modification of the perimeter landscape buffer provides for the optimal combination of on -site common area and residential units without violating other FWCC's or ordinances. FWCC 22-1565 explains that Type III landscaping "...is intended to provide partial visual separation of uses from streets and main arterials and between compatible uses so as to soften the appearance of parking areas and building elevations." On -site parking areas have been located between the rear fagade of adjacent townhome buildings to limit their visibility from the public right-of-way areas. No reduction in the perimeter buffer width along the western and southern property boundaries (adjacent to comparable multi -family residential zoned properties) is proposed. The project does plan to reduce the perimeter buffer area along the northern boundary adjacent to South 333rd Street and along the easterly property edge where the site abuts 24th Avenue South and Interstate No. 5. The preliminary landscape plans provided for the project (Exhibits K1 and K2) illustrate how the overall site design and proposed modifications to the perimeter landscaping achieve the stated purpose of FWCC 22- 1566(c)(3). Below -grade Surface Water Control Facilities FWCC 22-337(3) specifies that re -development projects not having Federal Way comprehensive plan designation of CC-F or CC-C shall construct above -grade water quality facilities. The project site is not located in either of these planning area designations. This suggests that above -grade water quality facilities would be necessary for the project unless a modification to this criteria is provided by the City's Stormwater Management Division. The project is requesting such a modification to allow a below -grade, combined detention/water quality vault to serve the site improvements. This modification is necessary to accommodate certain existing site constraints and to allow for optimal residential density conforming with other necessary land use codes and development standards, including provisions for on -site common open -space and perimeter landscape screens. The preliminary storm drainage system design for the project is in general accordance with the current Federal Way Surface Water Design Manual (FWSWDM) and FWCC Chapter 21, Surface and Stormwater Management. The FWSWDM provides design parameters for below -grade flow control and water quality facilities like those proposed for this project. A preliminary grading and storm drainage plan and details for the proposed below -grade stormwater vault (Exhibits J1 and J3) have been provided with the Use Process III application along with a preliminary Technical Information Report (TIR) for consideration of this request. 24th Avenue South Roadway Improvements The project site is currently accessed by both South 333rd Street and an existing paved private driveway along the eastern edge of the property. A portion of this private drive is located in the existing 24th Avenue South and Interstate No. 5 right-of-ways according to recent survey information. The encroaching portion of this private drive would be relocated into the existing 24-foot wide ingress/egress/utility easement along the eastern edge of the property along with other access improvements for the project. Federal Way Townhomes CPH Project No. 1706002 December 28, 2006 Page 3 of 3 The existing right -way of 24"h Avenue South terminates at an irregular shape near the middle portion of the eastern boundary of the property at the intersection of the westerly edge of the Interstate No. 5 right-of-way. The project proposes to dedicate the necessary public right-of-way width for 24th Avenue South up to this intersecting point of Interstate No. 5 to accommodate a modified Type "W" street section. This modified section would consist of a 24-foot pavement width with curb and gutter edges, and a 5-foot pedestrian sidewalk along the westerly edge. The public sidewalk would extend to the south property boundary in a public pedestrian easement. This proposed reduction in the standard Type "W" roadway section for 24th Avenue South is proposed in response to the existing site constraints created by the unique proximity/configuration of the property to Interstate No. 5 and the encumbrance of the current 24-foot wide access easement. Beyond the terminus of the widened 241h Avenue South right-of-way, the improved access drive would be privately owned and maintained to serve the southerly multi -family complex on the property and an existing off -site multi -family parcel. The existing 24-foot ingress/egress/utility easement that encumbers the easterly limit of the project site provides service to an occupied multi -family residential building south of the property (KC Parcel No. 7978200186). The residential parcels south of this off -site property (four residential parcels) have existing access from South 33611, Street. The improved 20-foot minimum width private drive proposed with this project maintains the existing condition and opportunities for future development of the off -site parcel without unnecessarily encumbering the subject property.

It summarizes the analysis criteria of the proposed storm drain collection and conveyance systems as well as the adequacy of existing storm water detention and water quality facilities for the project. The TIR also documents the basis of design of temporary erosion control and sediment retention facilities to be implemented during construction. Figure 1 provides the completed TIR Worksheet for this project. The Federal Way Townhomes project site is located at 2245 S. 333rd Street in the City of Federal Way. This site fronts the southerly edge of S. 333rd Street west of 24th Ave South. The property is located in the NE 1/4 of Section 36, Township 26 North, Range 4 East, W.M., King County, Washington and consists of a total of approximately 0.64 acres. Figure 2 provides a vicinity map highlighting the regional location of the project. ST �u �r r � NOT TO SCALE Figure 2 — Vicinity Map The current project proposes to develop 9 multifamily residential townhome units on the developable portion of the site in general accordance with the applicable City of Federal Way (COFW) codes and development standards. Access to these units will be provided by a paved private drive which runs southerly from the intersection of 24+h Avenue South 333,d Street. Each residential unit contains a two CP I H CONSULTANTS June 21, 2007 CPH Project No. 1706002 Page 1 Federal Way Townhomes Preliminary Technical Information Report car garage. Water and sanitary sewer service to the units will be provided by an extension of the existing Lakehaven Utility District (LUD) mains located along the north and south property boundaries. Storm water flow control for the project is proposed by means of an on -site, below grade vault facility. The lower volume of this vault will accommodate a permanent wet pool for water quality treatment. This facility is to be located in the northern portion of the development (under the private driveway that serves the northerly townhome units). A series of on -site and off -site catch basin inlets and underground pipes will collect and convey surface water runoff from the majority of the developed site to the storm water vault. Detained and treated discharges from the vault are conveyed northerly and westerly by a series of underground pipes to an existing catch basin located along the southern edge of South 333,-d Street west of the northwest corner of the property. Onsite Soil Conditions Onsite soils have been identified as Alderwood gravelly, sandy, loam (AgB) according to current Natural Resources Conservation Service (NRCS) sources. These soils are characterized as SCS hydrologic class C soils in the City of Federal Way Surface Water Design Manual (FWSWDM). This soil group generally supports slopes ranging from 0-6%, and has slow infiltration rates when thoroughly wetted. The type C-category consists primarily of soils with an underlying layer that impedes the downward movement of water, or soils with moderate to fine textures. Figure 3 provides a general regional soils map containing the project site. AgB.

The storm water design criteria for the project are listed below. FWSWDM Core Requirements 1. Discharge at Natural Location: The project site has natural or existing grades that slope very moderately southerly and westerly. A small area covering the southeastern portion of the access drive drains southerly toward an existing off -site development. Site discharges travel as sheet and shallow flow concentrated flows toward an existing culvert out -fall located southwest of the property. The proposed development of the property will maintain this general natural discharge pattern in general accordance with FWSWDM standards. The existing site conditions are further described in Section 3 of this report. 2. Offsite Analysis: Summarized in Section 3 — Offsite Analysis. 3. Flow Control: Level 1 Flow Control standards are proposed for the project in accordance with FWSWDM criteria. 4. Conveyance System: Summarized in Section 5 - Conveyance System Analysis and Design. 5. Erosion and Sediment Control: Described in Section 8 - Erosion and Sedimentation Control Analysis and Design. 6. Maintenance and Operations: The on -site drainage facilities are proposed to be privately maintained and operated. Section 10 of this report provides additional information regarding facility maintenance and operations. 7. Financial Guarantees and Liability: See Section 9 - Bond Quantity Worksheet. 8. Water Quality: A permanent wet pool volume is proposed beneath the active storage volume in the detention vault to provide basic water quality treatment in accordance with current FWSWDM standards. FWSWDM Special Requirements 1. Other Adopted Area -Specific Requirements: No area -specific requirements apply to this project site. 2. Flood Hazard Area Delineation: The limits of this project are not located within a 100-year floodplain. 3. Flood Protection Facilities: Not applicable. 4. Source Control: No additional source control is proposed. 5. Oil Control: Oil control for storm water discharges will be provided by the configuration of the riser control structure within the combined detention and water quality vault facility. CP I H CONSULTANTS June 21, 2007 CPH Project No. 1706002 Page 3 Federal Way Townhomes Preliminary Technical Information Report SECTION 3 - OFF -SITE ANALYSIS Task 1: Study Area Definition and Maps The project site is fronted by South 333rd Street along its north property line and is located west of 24th Ave South. There are two existing single family residences located on the parcel near the northern property boundary. The properties south and west of the site are developed and directly east of the site lies Interstate 5. More generally, the site is located in the NE �/4 of Section 36, Township 26 North, Range 4 East of King County, Washington (see Figure 2, Vicinity Map). The project site has a total area of 0.64 acres with a net developable area of approximately 0.45 acres. Task 2: Resource Review No wetland or stream resources are located on the project site according to observations and available agency data. The project lies in an area that has a low probability of ground water contamination per current King County GIS resources. There are drainage complaints listed on parcels near the site, but none of these complaints have occurred within the last ten years and were not results of conditions related to the subject property. As such, they have been omitted from this report. There were no drainage complaints pertaining directly to the proposed project site according to review of the available resources. The project site is not located within a delineated 100-year flood plain area. Hylebos Creek and an unnamed Class 2S stream, are located downstream of the project site. Both waterways flow southerly within 200 feet of the western property boundary. The stream reaches in proximity to the project site are currently continued in an underground 42-in. pipe. This pipe discharges to a daylight outfall approximately 150 feet southwest of the southwest property corner. Task 3: Field Inspection A field investigation of the site was conducted on Tuesday, May 16, 2006 on a clear and dry day. The temperature on the day of this visit was approximately 60 degrees. This investigation included observations of current land use, ground cover, topographic conditions, and existing drainage patterns. Currently there are two single-family residences located on -site, but only one of the residences is inhabited. The neighboring properties to the west and south are developed with single-family residences. The site is generally flat with slopes ranging from 1 % to 3%. This site is currently cleared with some gravel surfacing and areas of managed, grass landscape. The majority of the developable area of the property drains southerly and westerly toward an existing off -site Class 2S stream and Hylebos Creek. These existing site conditions are shown in Figure 3. The Off -site Analysis Table provided in Appendix E lists the components of the downstream drainage system and conditions of each individual reach. Downstream Basin Surface water runoff from the existing site travels as mostly sheet flow toward the off -site Class 2S stream as well as Hylebos Creek which are both located to the west of the site. The surface water runoff travels in a southwesterly direction onto the neighboring properties before being discharged to the two streams. The neighboring properties are currently developed with multi -family residential lots and are mostly cleared with moderate landscape cover and paved driveway areas. CP I H CONSULTANTS June 21, 2007 CPH Project No. 1706002 Page 4 Federal Way Townhomes Preliminary Technical Information Report Upstream Basin The general topography of the site and improved conditions of South 333rd Street effectively limit off - site, upstream runoff contributions to a portion of the paved roadway area north of the site and an area east of the site that is currently covered with tall grass and shrubs (shoulder and slope areas of Interstate 5). These off -site contributing areas drain toward the north and east property boundaries. These off -site contributing areas have been accounted for in the hydrologic analysis for this project as described in Section 4 of this report. Task 4: Drainage System Description The on -site storm water collection, conveyance, and water quality systems supporting this project are proposed in general accordance with the provisions of the Federal Way Surface Water Design Manual (FWSWDM). This on -site system includes a series of catch basins that will collect the surface water runoff from the developed portions of this site. A series of underground pipes will convey the surface water to a vault designed for both flow control (i.e., detention) and water quality purposes. The vault wit! discharge to a series of catch basins and underground pipes that will convey the surface water runoff northerly and westerly to an existing off -site catch basin along the south edge of South 333rd Street. This catch basin discharges southerly via an approximately 370-foot length of 42-in. pipe to a daylight outfall located approximately 150-feet southwest of the project site. The proposed site drainage improvements are shown on Figure 5 of this report. Task 5: Mitigation of Existing or Potential Problems There are no documented downstream flooding or drainage system problems that would require specific mitigation by the proposed project. The proposed drainage systems for the project have been designed in accordance with current FWSWDM standards including Level 1 Flow Control criteria. As such, the proposed storm water collection, conveyance, and water quality systems are anticipated to provide adequate measures to mitigate any potential impacts to the downstream system. Temporary Erosion and Sedimentation Control (TESC) measures will be implemented during construction operations in accordance with development standards. All TESC facilities will be actively inspected and maintained by the contractor during construction to minimize impacts to the downstream system as described in Section 8 of this report and the project plans. CP I H CONSULTANTS June 21, 2007 CPH Project No. 1706002 Page 5 Federal Way Townhomes Preliminary Technical Information Report SECTION 4 - FLOW CONTROL AND WATER QUALITY FACILITY ANALYSIS AND DESIGN The hydrologic analysis of the runoff conditions for the project site is based on drainage characteristics such as basin area, soil type, and land use (i.e., pervious, impervious, density). The King County Runoff Time Series (KCRTS) software was used to evaluate the storm water runoff conditions for the project site and to design the on -site flow control facilities. The following is a summary of the results of the analysis and the proposed drainage facility improvements for this project: Existing Site Hydrology The existing on -site and off -site drainage sub -basins and associated contributing areas are shown on Figure 3 of this report. The contributing runoff area of the site that will contain the proposed improvements is designated as Basin El. The topography within this on -site basin tends southwesterly toward low points near the central portion of the west property boundary and at the intersection of the south and west property boundary. An upland off -site area east of the site drains westerly toward the subject property and has been designated as E02. Slopes within this subject area range from approximately 2% to 3%. Pre -developed conditions were considered as cleared and partially improved based on available records, including a circa 1977 aerial photograph provided by Aero-Metric (see Figure 4). This aerial photograph shows the subject property as being cleared and developed with dirt/gravel driveways and two residential structures (that exist today). Table 4.1 summarizes the Basin areas and KCRTS input parameters used in the analysis of the existing (i.e., pre -developed) site conditions. Table 4.2 is a summary of the discharges generated under predeveloped conditions.

The grading efforts, and associated drainage collection and conveyance systems, will generally maintain the existing discharge patterns of the subject site and neighboring properties. Figure 5 shows the proposed grading and drainage improvements and sub -basin delineation for the developed site. CP I H CoNsuLTANTs June 21, 2007 CPH Project No. 1706002 Page 6 Federal Way Townhomes Preliminary Technical Information Report Basin P1 contains the on -site paved, landscaping and the residential townhome buildings proposed with the project. The majority of the private access drive is also included in basin P1. A limited portion of the private access drive in the vicinity of the south east corner of the site is too low to be collected by the on -site conveyance system and is considered as a bypass in the hydrologic analysis for the project. This basin has been designated as P2. Two other small areas of the developed site will also bypass the project's conveyance system. The south half of South 333rd Street (including pavement widening and sidewalk improvements) along with a limited landscape portion of the developed property along the north frontage will also bypass the proposed storm drainage control facilities. This sub -basin has been designated as POI -A, as shown in Figure 5. Sub -basin P3 is an on -site bypass sub -basin that includes the landscape area along the west property boundary. An upland off -site area has been included in the site hydrologic analysis. This sub -basin has been designated as P02 and includes tall grass and shrubs (shoulder and slope areas of Interstate 5) and limited impervious surfaces. This developed sub -basin slopes towards the east property boundary at grades ranging from 2% to 3%. A second upland off -site area has also been included in the site hydrologic analysis. This sub -basin has been designated as P01-B and includes impervious surfaces and limited landscape areas. This developed sub -basin slopes easterly along the north property frontage at grades ranging from 2% to 2.5%. Impervious area contributions from sub -basins P02 and PO1-B to the on -site flow control and water quality facilities are equivalent to that of the bypassed sub -basins (P3, P4, P01-A) that will not be collected by the onsite systems. Table 4.4 is a summary of the discharges from the un-captured bypass sub -basins and the equivalent sub -basin to be captured, as calculated using the King County Runoff Time Series (KCRTS) program. Summaries of the measured pervious and impervious areas for each subbasin under developed site conditions are shown below in Table 4.3. The total on -site impervious area shown in this table represents roadway, parking, sidewalks, and building roofs with any adjustments as discussed above. On -site pervious areas have been considered as Till Grass land cover for this analysis.

On -site water quality treatment facilities are required for the project according to section 1.2.8 of the FWSDWDM. Table 4.5 summarizes the design criteria for the on -site vault facility. Table 4.5 - Performance Standards Facility Flow Control Standard Water Quality Treatment Standard On -site Vault Level 1 Basic Flow Control and Water Quality Facilities Section 4.5.1 of the City of Federal Way Public Works Development Standards recommends that retention/detention facilities be constructed above ground in open ponds. Further, section 4.4_6 of the City of Federal Way Public Works Development Standards requires water quality facilities for residential projects be constructed above ground. These standards and current FWSWDM standards provide for alternate below grade facilities if existing site constraints justify such considerations. A below grade vault facility is proposed for this project to accommodate both existing site constraints and to allow for other site features required by other City of Federal Way Municipal Code and Public Works design standards. An existing 24-foot utility and ingress/egress easement is located along the east frontage of the property. This easement occupies a significant amount of the property and requires additional zoning setbacks (including landscape screens) that further constrain the property and limits available open space for surface type stormwater facilities. The 0.61 acre site is zoned RM-2400 and allows for a maximum of 11 multi -family residential units. The proposed residential density has been reduced to 9 units to allow for site access and required common/recreational space areas on -site. The zoning and current city design standards also require 10-foot perimeter landscape buffers at adjacent property boundaries and 20-foot buffer screens along all street frontages (including the existing easement along the east boundary). Surface stormwater facilities are not compatible with the design requirements of these required landscape features. The remaining on -site open space areas not occupied by structures, access drives, or required landscape and common/recreation areas are not adequate for surface drainage facilities. The shape of the property, current topography, and location of existing storm drainage facilities (for connection by on -site features) further constrain the project and serve as justification for below grade flow control and water quality facilities. The site currently drains toward the south and west. There are no easements or existing storm drainage facilities for connection at the south or west property boundaries. As such, the project proposes to re - grade the site to collect on -site and contributing off -site drainage areas and convey volumes to the existing street drainage system at South 333rd Street. The current site topography and existing depth of the street drainage system — combined with the other discussed site constraints — make a below grade drainage system the most efficient and practical solution to optimize the residential density and maintain aesthetic features for the property. A standard flow control riser is proposed at the outlet of the on -site detention vault to control the release rate of storm water to the offsite, downstream systems. The size and number of control orifices CP I H CONSULTANTS June 21, 2007 CPH Project No. 1706002 Page 8 Federal Way Townhomes Preliminary Technical Information Report on this riser have been designed to control the on -site release rate to pre -developed site conditions for the 2-year and 10-year storm events. The calculated release rates of the off -site and on -site bypass areas have been subtracted from the allowable release rates from the vault. Table 4.6 provides a summary of the flow control criteria determined for the project. The KCRTS model results and/or calculations for this detention volume sizing are provided in Appendix D.

The proposed facilities have been selected in accordance with FWSWDM standards. In addition to these site -specific TESC measures, the following general Best Management Practices (BMPs) for sediment control shall also be implemented: 1. Clearing Limits Construction clearing limits fence or silt fence will be installed by the contractor along the entire project corridor to prevent disturbance of project areas not designated for construction. These fences will be installed prior to clearing and grading activities where appropriate. 2. Cover Measures Temporary and permanent cover measures will be provided by the contractor to protect disturbed areas. Disturbed areas will be seeded and mulched to provide permanent cover measure and to reduce erosion within seven days, if those areas not scheduled for immediate work. 3. Perimeter Protection The contractor will install silt fences as indicated on the drawings prior to any up slope clearing, grading and trenching activities in order to reduce the transport of sediment offsite. 4. Traffic Area Stabilization Stabilized pads of quarry spalls will be installed by the contractor at all egress points from the project site as required to reduce the amount of sediment transported onto paved roads or other offsite areas by motor vehicles. 5. Sediment Retention Sediment retention will be provided by silt fencing and catch basin inlet protection at the locations and dimensions shown on the project drawings. 6. Surface Water Control Surface water control will include ditches, temporary culverts check dams, and/or other inlet and outlet protection as required and/or at the locations and dimensions shown on the drawings. 7. Dust Control Water and/or street sweeping equipment will be used by the contractor to control dust emissions during construction operations as required. 8. Wet Season Requirements If soils are exposed during the period of October 1 to March 31, the contractor will mulch and seed or otherwise cover as much disturbed area as possible by the first week of October, in order to provide protective ground cover for the wet season. The contractor will also conform to the following wet season special provisions: A. Apply cover measures to disturbed areas that are to remain unworked for more than two days. CP I H CONSULTANTS June 21, 2007 CPH Project No. 1706002 Page 13 Federal Way Townhomes Preliminary Technical Information Report B. Protect stockpiles that are to remain unworked for more than 12 hours. No area is to be left uncovered/denuded longer than 12 hours during the winter months. C. Provide onsite stockpiles of cover materials sufficient to cover all disturbed areas. D. Seed all areas that are to be unworked during the wet season by the end of the first week of October. E. Apply mulch to all seeded areas for protection. F. Provide onsite storage of 50 linear feet of silt fence (and the necessary stakes) for every acre of disturbed area. Straw bales are to be stockpiled onsite for use in an emergency. G. Provide construction road and parking lot stabilization areas for all sites. H. Provide additional sediment retention as required by the City of Federal Way Engineer. I. Provide additional surface water controls as required by the City of Federal Way Engineer. J. Implement construction phasing and more conservative BMPs for construction activity near surface waters (to be evaluated). K. Review and maintain TESC measures on a weekly basis and within 24-hours after any runoff - producing event. 9. Sensitive Areas Restrictions Clearing and grading within the on -site wetland buffers shall be limited to that necessary to prepare this area for the proposed buffer mitigation or incidental and temporary disturbances related to the site development activities as shown in the accompanying construction and mitigation plans. 10. Maintenance Requirements All TESC measures will be maintained and reviewed on a regular basis following the standard maintenance requirements identified in the project drawings. A TESC supervisor will be designated by the contractor and the name, address and phone number of the TESC supervisor will be given to the City prior to the start of construction. A sign will be posted at the primary entrance to the project site identifying the TESC supervisor and his/her phone number. The TESC supervisor will inspect the site at least once a month during the dry season, weekly during the wet season, and within 24 hours of each runoff -producing storm. A standard TESC maintenance report will be used as a written record of all maintenance. The contractor will be responsible for phasing of erosion and sediment controls during construction so that they are coordinated with construction activities. The contractor will also be responsible for maintenance of temporary controls during construction, including removal of accumulated sediment, and for the removal of the controls and remaining accumulated sediment at the completion of construction. 11. Final Stabilization Prior to obtaining final construction approval, the site shall be stabilized, the structural ESC measures removed and drainage facilities cleaned. To obtain final construction approval, the following conditions must be met: All disturbed areas of the site should be vegetated or otherwise permanently stabilized in accordance with project BMPs. At a minimum, disturbed areas should be seeded and mulched to provide a high likelihood that sufficient cover will develop shortly after final approval. The plans include erosion control notes and specifications for hydro -seeding and mulching disturbed areas. Structural measures such as silt fences, pipe slope drains, storm drain inlet protection and sediment traps and ponds shall be removed once the proposed improvements are complete and vegetated areas are CP I H CONSULTANTS June 21, 2007 CPH Project No. 1706002 Page 14 Federal Way Townhomes Preliminary Technical Information Report stabilized. All permanent surface water facilities shall be cleaned completely and restored to working order prior to removal of TESC facilities.

Only persons who submit written comments to the Director, or specifically request a copy of the decision, may appeal the Process III decision. Details of appeal procedures for the requested land use decision will be included with the written decision. Optional Environmental Determination: Based upon review of a completed environmental checklist and other information on file with the City, it is likely that the City of Federal Way will determine that the project will not have a probable significant adverse impact on the environment. It is likely that an environmental impact statement (EIS) will not be required under RCW 43.2 1 C.030(2)(c). The City anticipates that a Determination of Nonsignificance (DNS) will be issued for the proposed project. The optional DNS process of WAC 197-11-355 is being used. The proposal may include mitigation measures under applicable codes, and the project review process may incorporate or require mitigation measures regardless of whether an EIS is prepared. A copy of the subsequent threshold determination for the specific proposal may be obtained upon request. (hi addition, the lead agency may choose to maintain a general mailing list for threshold determination distribution.) Integrated Comment Period: Consistent with the provisions of WAC 197-11-355, a single integrated comment period will be utilized to obtain comments on the Notice of Application and Optional Environmental Determination. This may be the only opportunity to comment on the environmental impacts of the proposal. Any person may submit written comments on the environmental impacts of the proposal to the Director of Community Development Services by the comment deadline (noted above). Any interested party may appeal the environmental threshold determination. Details of appeal procedures for the requested environmental decision will be included with the written decision. Issuance of Final Environmental Determination: If timely comments do not identify probable significant adverse impacts that were not considered by the Optional Environmental Determination, the DNS will be issued without a second comment period. A copy of the DNS may be obtained upon request. Consistency with Applicable City Plans and Regulations: The project will be reviewed in accordance with Federal Way City Code (Chapter 22, Zoning), the King County Surface Water Design Manual, Federal Way Road Standards/King County Road Standards, and any other applicable regulations. The official project file is available for public review at the Dept. of Community Development Services, 33325 8`h Avenue South. Comments may be mailed to PO Box 9718, Federal Way, WA 98063 or delivered in person.

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 information 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 your 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 really 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 the 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 questions apply to all 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 (part D). 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.
