On October 2"d, we received a letter from Mr. Hansen, the Planning Manager, asking to send an additional request in order for them to approve the short plat. In the letter he stated that there is no mechanism in the code to modify the fee - in -lieu payment percentage as we requested due to the disproportionate right-of-way dedication required. The subject property comprises of King County tax parcel 242103-9018, a total of 2.53 acres, located in the southwestern portion of Federal Way adjacent to SW 344th Street and 18th Avenue SW. According to FWRC 18.55.060(2),15% of the gross land area of the subdivision site is required to provide open space, or 16,553 SF. The proposed short plat includes eight (8) single-family residences, right-of-way dedications and associated infrastructure. This project previously proposed to incorporate an undeveloped area as conservation open space that met and exceeded the maximum 5% allowed, with the request to pay a fee -in -lieu of the required 10% of usable open space. Due to the City's decision to have this project dedicate additional land for the future SW 344th Street right-of-way, that open space opportunity has been eliminated. As such, we would like to request to pay a fee -in -lieu of open space for 15% of the most recent assessed value of the property. The 2019 tax year's appraised land value is $194,000 which produces a fee that equates to $29,100. 33400 Sth Ave S Ste 205 Tel (253) 836 6113 Everett (425) 297 9900 i i, it E L and Piammng Federal Way.

Pursuant to Federal Way Revised Corte (FWRC) 19.55.060, all residential subdivisions are required to provide open space in the amount of 15 percent of the gross land area of the subdivision site. The subject property gross land area is 110,335 square feet and would be required to provide 16,551 square feet of open space. If open space is not fiAMed on -site a payment of an equivalent fee in lieu of the required project open space is allowed. The Fee -in -lieu of open space shall be calculated on 15 percent of the most recent assessed value of the property, at the time of recording. Currently, the open space fee -in -lieu payment will be,$29,100 (2018 appraised land value $194,000 x 15 percent). Per the request, you would like to pay a fee -in -lieu of the difference of the 15 percent required and the 14,667 square feet of excess right-of-way dedication, as shown below: Adjusted Open Space Required = 16,553—14,667 = 1,886 sq. ft. Current Assessed Value = $177,000 Existing Site Square Footage = 110,335 sq. ft. Adjusted Open Space Required * Current Assessed Value/sq. ft. = $3,026Open Space Fee -in -Lieu Pursuant to FWRC 18.55.060(3), an administrative alteration of the open space category percentage requirements may be made by the parks director, but in no case less than 15 percent. However, there is no mechanism in the code to modify the fee -in -lieu payment percentage. At this time, the city cannot approve the request to revise the fee -in -lieu payment. In order to approve the short plat, a revised letter to Parks DirectorJohn Hutton requesting a fee -in -lieu payment for 15 percent of the most recent assessed value of the property must be submitted per FWRC 18.55.060(2).

This resubmittal includes materials that address comments received from various departments involved with review of the Pena Short Subdivision application, dated March 16, 2018 from the City of Federal Way. Please note that the right-of-way modification decision by the City of Federal Way Public Works department, dated July 25, 2018, has resulted in a layout and lot count change. The previously proposed Open Space/Tree Retention Tract has been removed and the proposed lots now utilize the space that remains on the property as back -yards. Furthermore, an 8th single-family lot has been added to the proposal. There are 9 tracts/lots in total, including the storm tract, to maintain this project's qualifications as a short subdivision. Please find the following enclosed materials as part of this resubmittal. 1. Technical Comment Letter and ROW Decision Responses (this letter); 2.

Deputyaeputy Public Works Director - Final ROW Modification Request Response Since there has been no application for development and no dedication of right-of- way from the property to the north, staff cannot anticipate when development will occur. Therefore, your request to modify the dedication requirement from 39 feet to 28 feet does not meet the criteria for modification outlined in Federal Way Revised Code Section 19-135.040(4)(a) and (b) Authority to Require Dedication. In addition, this code section allows the Public Works Director to reduce the size of the dedication but does not require that it be reduced based on average daily trips. If that applicant is able to obtain a public right-of-way dedication of 50' from the property to the north, then a right-of-way dedication of 28 feet along the Pena frontage of SW 344th Street will be adequate, based on the alignment provided on the exhibit. Until the dedication is provided via statutory warranty deed meeting City of Federal Way legal requirements, the applicant is required to provide a thirty -nine -foot right-of- way dedication on SW 344th Street. We understand that WSDOT has not yet submitted for a development application. The section of code that describes this condition in no way implies that a development application must be submitted from the adjacent property for FWRC 19- 135.040(4)(a) to apply. However, we are aware, as is the City of Federal Way staff, that WSDOT intends on selling the undeveloped portion of the property in the near future. This will likely result in an application for development, which will require a land use approval from the City of Federal Way. As such, this project will comply with the 39' right-of-way dedication under the condition that the property to the north does not make public notice of their intent to submit a land use permit application to the City of Federal Way prior to the final short plat recording. Otherwise, a right-of-way dedication of 28' along the Pena frontage of SW 344th Street will be adequate to serve this project. The initial response provided by the City indicated that the modification waiver will be applicable for a period of one year from the date of the letter (February 21, 2018), and if the project is not completed within the one-year time limit, the waiver for frontage improvements along SW 344th Street will be void. We would like to request that the City extend the time limit of the waiver to final approval of the preliminary short plat, at which point the waiver will be secured. Beck Cha in PlanningDivision 253-835-2641 . bec cha ingci otfederalwa .coin Setbacks - Per FWRC 19. 05.180, definition of 'Required Yard' (enclosed) the required front yard setback for Lot 6 is measured from the edge of the vehicular access easement. The building setback line must be depicted 20 feet from the edge of the 20-foot access easement. Lot 7 is considered a flag lot. Refer to FWRC 19.05.160, "Property line " (enclosed) for how required yards are applied for flag lots Lots 1 and 7 are not considered corner lots and therefore the 10-foot side yard setback is not required. The building setback line along the west side of Lot 1 and east side of Lot 7 should be depicted as 5 feet. Ms. Becky Chapin September 11, 2018 Page 3 Setback lines from the access easement for Lots 6, 7 and 8, previous 6 and 7, have been revised to reflect 20' from the easement line. Lots 1 and 8 (previously Lot 7) have revised side yard setbacks 5' from property line. 2. Open Space - Right-of-way (ROW) dedication area cannot be used for on -site open space requirements. Based on the 39-foot ROW dedication requirement along SW 344h Street, the area of "Tract A" open space has been significantly reduced. Please provide an updated statement explaining how open space shall be provided. A revised open space request letter to Parks Director John Hutton may be required if there is a change in the fee -in -lieu payment amount. Due to the right-of-way dedication decision from the City of Federal Way Public Works department, dated July 25, 2018, the Open Space tract has been removed from the site plan. With approximately one-third of the project site dedicated to the City, there is limited space for a reasonable lot count and open space. A revised open space request letter is included with this resubmittal. 3. Tree Retention Plan - The tree unit calculation must be revised to reflect the 39-foot ROW dedication. The area of dedicated ROW cannot be calculated in the site acreage for calculating the total number of tree units, nor can the trees in this area be used for tree retention for the project. A Landscape and Tree Replacement Plan has been prepared for this project site as a revision to the original Tree Retention Plan. With the reduction in open space available for this project, tree retention is met through replacement trees between all lots and the storm tract.

Technical Memorandum To: Becky Chapin, City of Federal Way From: Kevin O'Brien, Senior Ecologist Stephanie Modjeski, Wetland biologist Copies: File Date: May 22, 2018 Subject: Review of Pena Short Plat Critical Areas Assessment, Parcel #242103-9018 Project No.: 32285.J The City of Federal Way (City) requested Otak, Inc. (Otak) conduct a review of the Critical Areas Assessment prepared by Habitat Technologies, dated October 25, 2017 for Parcel #2421039018. The applicant is proposing to subdivide the 2.5-acre site into a 7-lot short plat. The critical areas assessment, data, and associated information were reviewed in accordance with Federal Way Revised Code (FWRC) Chapter 19.145 (Environmentally Critical Areas) Article III (Fish and Wildlife Habitat Conservation Areas) and Article IV (Wetlands). The subject property is located at SW 344th Place and 16th Avenue SW, in Federal Way, King County. The parcel is located in Township 21 North, Range 03 East, Section 24 in Water Resource Inventory Area (WRIA) 10 (Puyallap-White). Otak biologists completed a site visit of the subject property on May 4, 2018. Documents Reviewed ■ Critical Areas Assessment, prepared by Habitat Technologies, October 25, 2017 • Preliminary Engineering Plan Set, prepared by ESM, December 27, 2017 • City of Federal Way's Critical Areas Map The following resources were also reviewed on May 3, 2018 as part of the background research prior to the site investigation: ■ City of Federal Way Critical Areas Map htt :llwww.cit offederalwa .comisitesldefau€tlfi{eslma slsensitive 2016, df) • Google Earth Pro • King County iMap ffittr0la isms s.kin cou MY, govhMapl) • United States Department of Agriculture -National Resource Conservation Service (USDA-NRCS) Web Soil Survey (htt s:/lwebsoiisurve .sc.e ov.usda, ov1A IHomePa e.htm ■ U.S. Fish and Wildlife (USFW) —National Wetland Inventory (NWI) (https'1lwww.fws_gov/wetiands/datalmapperIHTIv, L) • Washington State Department of Natural Resources (DNR)- Washington LIDAR Portal (http://Iidar ortai dnr.wa <iovl#47.45403:_-122.21724:17) 2731 Wetmore Avenue, Suite 300 Everett, WA 98201 • Phone (425)493-5221 otak.com Critical Areas Assessment Review for Pena Short Plat Page 2 May 11, 2018 • DNR — Forest Practices Application Mapping Tool (htt s://fortress.wa. ov/dnrl rotecticn islf amt/default_as x) • Washington Department of Fish and Wildlife (WDFW) — SalmonScape (http.//?pp-a.wdfw.wa.gov/salmonscape/map.htm]) • WDFW — Priority Habitats and Species (PHS) on the Web(http://apps.wdfw.wa.gov/phsontheweb/) • Federal Way Revised Code (FWRC) (http:/rwww.codepublishing.comlWA/FederalWay/?FederalWayl9/FederaiWayl9l90.html&?f ) Findings The critical areas report from Habitat Technologies identifies a culvert near the north -central boundary of the project site that discharged to an excavated ditch. The culvert and ditch are located along a utility corridor, north of the subject property. The ditch terminates at the western end of the utility corridor. The ditch was determined to be an excavated, drainage feature. Surface water runoff flows into a regional stormwater drainage that directs surface water north, along the eastern boundary of the Twin Lakes Park and Ride facility, northwest of the subject property. The critical areas report did not identify any critical areas on the subject property. The City's Critical Area Map identifies an off -site wetland northwest of the subject property and a stream west of the property, flowing south to north and discharging to the mapped wetland. The findings of our report review and site investigation are as follows: A large approximately 4-foot round culvert is located at the north eastern corner of SW 344'h Street, off site and within a King County Transit -owned parcel.. This culvert discharges to a wetland, identified on the City's Critical Areas Map. Flow through the culvert likely emanates from constructed stormwater retention facilities located within the adjacent residential neighborhood. The wetland receives hydrology from culvert discharge. Dominant vegetation includes black cottonwood (Populus balsamifera spp. trichocarpa), red alder (A/nus rubra), creeping buttercup (Ranunculus repens), Himalayan blackberry (Rubus armeniacus), and reed canarygrass (Phalaris arundinacea). Large patches of bare ground and algal mats were present, suggesting seasonal ponding. The wetland does not extend onto the subject property, but continues to the north and east. Another concrete culvert, located further east and likewise north of the subject property, was identified during the site visit. Surface water was present at the culvert outlet. The culvert contributes water to an excavated ditch that runs east -west to the north of the subject property line, appearing to occur off -site as well. The ditch was filled with angular rock and dissipated at the westernmost end of the easement. A small topographical depression was identified east of the culvert. Several soil pits were dug within the depression. Soils were generally dry, and had a matrix color of 10YR 3/4 with redox concentrations. Although soils displayed redoximorphic features, it is likely they are relictual in nature. There were no other indicators of hydrology or wetland vegetation within this area. No critical areas were identified on the subject property. The property is generally upland deciduous forest. Dominant species include black cottonwood, red alder, big leaf maple (Acermacrophyllum), Himalayan blackberry, English hawthorn (Crataegus monogyna), bedstraw (Galium aparine), osoberry (Oem/eria cerasiformis), and bracken fern (Pteridium aquilinum). Critical Areas Assessment Review for Pena Short Plat Page 3 May 11, 2018 Conclusion We concur with Habitat Technologies report concluding that no critical areas occur on the subject property. The on -site habitat does not meet the three criteria (hydrology, hydric soils, hydrophytic plant community) necessary for a jurisdictional wetland. The off -site drainage features to the north and northwest of the subject property appear to be an intermittent watercourse that would likely be classified as Type Ns (seasonal non -fish habitat) per FWRC 19.145.260, but would not have any associated buffers because it appears to have been artificially created in uplands and would be exempt from FWRC per Chapter 19.145.110(3). The subject property does not contain habitat with a primary association with state or federally listed species, habitat for state priority species, or habitats/species of local importance. The off -site wetland to the north west of the subject property should be rated using the Washington State Wetland Rating System for Western Washington — 2014 Update (Hruby 2014) to determine buffer widths per FWRC 19.145.420 (Wetland rating and buffers) as the buffer may extend onto the subject property.

Please have the applicant make the following revisions: Technical Information Report 1. Please provide a separate breakdown of all pollution -generating impervious, non -pollution generating impervious, and pervious surfaces used for the storm water calculations. The entire site (2.53 acres) must be accounted for. 2. Provide a downstream analysis and associated map that extends at least 1/4 mile downstream. The infiltration pond across the street is not 1/4 mile downstream of this site. 3. It appears that the proposal to send storm water runoff from the frontage improvements (approximately 0.24 acre) to the existing infiltration pond is feasible, however additional backup information and study will be required. It is recommended that the entire project be detained (or over -detained if grades prohibit actual detention of frontage improvements) and treated onsite. Engineering Plans 4. Revise the plans to reflect the 39 foot right-of-way dedication on SW 344th Street, as required by the approved right-of-way modification. 5. Show streetlights conceptually on the plans. 6. Revise the Native Growth Credit based on the approved right-of-way modification on SW 344th Street. 7. Topsoil and soil amendment must be added to any new impervious area that will be constructed as part of these plans. Please show on the drawings and include a note per the 2016 King County Surface Water Design Manual (KCSWDM) Section 1.2.9.2.1. Plat Map 8. Show the city file number in the top left corner of the sheets. 9. Revise the plans to reflect the 39 foot right-of-way dedication on SW 344th Street, as required by the approved right-of-way modification. 10. If flow control BMP's are proposed on each individual lot and not constructed as part of the engineering for this short plat, a note explaining this requirement must be placed on the plat map. A note requiring top soil amendment per KCSWDM Section 1.2.9.2.1 must also be placed on the plat map. p Y U p C g N tp N o O N U O O .- E U d+-i LL p L t`O tp �N� 1 H cm O�Ut` O>e^G�d EC .p OUd i IS a O a`i m �� O �. 2 w N O Y w li C N O A fp G�.l VJ N U C tp EL Z J ^ G1 O _ T 06 = .` W e L C m .- O �m cN o ia 0- QL pp y a� ca y� c O r d m y __ U S ZI y N C ;c m y m- C c ^2 LJ.I z C N GJ O.Li = U U wO L C N f0 U h Q) y L >i C/i L C fp C tl] O "U U LL a p V Z E 2 cp c C] U _� c a aoi .L" c >.

The project is located at SW 344th Place and 16th Ave SW. Under current boundaries, this development is in the Sherwood Forest Elementary, Illahee Middle School, and Todd Beamer High School service areas. School service areas are reviewed each year and necessary boundary changes may be made to accommodate enrollment increases. Students living in this area receive school bus transportation to Illahee Middle School and Todd Beamer High School. Bus stops are reviewed annually as student transportation needs change. The closest stop for Illahee Middle School and Todd Beamer High School is at 34446 18th Ave SW. Students living in this area for Sherwood Forest Elementary walk to school. Student safety must be considered for all students. We ask the developer to prepare a "School Access Analysis" for this proposed development. The analysis will include safe walking plans for students who would walk to and from schools and to and from school bus stops, with school location, large bus access plans, description of sidewalks, pedestrian paths, road shoulders, location of crosswalks, etc. The analysis will also include plans for our special needs students who require door-to-door transportation, with small bus access plans. All planning features that assure safe transportation for students are factors the district must consider as we comment on development within our service areas. Attached are guidelines for preparing this analysis. The most recent Federal Way School District Capital Facilities Plan indicates a student yield of .4830 from new single-family housing. This development could add about three or four new students. These are averages only; the actual number of students may vary. This may create a need for additional space, equipment and staff. This impact is mitigated by the collection of impact fees. The District appreciates the opportunity to comment on this proposed development. Sincerely, Jennifer Wojciechowski Student & Demographic Forecaster cc: Sally McLean, Assistant Superintendent of Finance and Operations Paul Vang, Security and Safety Manager Mike Benzien, Executive Director of Operations Michelle Turner, Director of Transportation Each Scholar.

The subject project is currently awaiting approval with the City's Planning Department. The property comprises of King County tax parcel 242103-9018, a total of 2.53 acres, located in the southwestern portion of Federal Way adjacent to SW 344th Street and 18th Avenue SW. The proposed short plat includes seven (7) single-family residences, right-of-way dedications and associated infrastructure. A tract for conservation open space/tree retention is included in the proposed project that exceeds the 15% open space area requirement. However, due to the size constraints, there is not available space to adequately provide 10% of usable open space. King County has the property assessed at a taxable total value of $177,000 (2018 tax year). We are requesting a fee -in -lieu of $17,700 for the remaining 10% of usable open space required be applied to this short subdivision to fund existing or future City parks projects.

The Pena Short Plat II project includes King County tax parcel 242103-9018, which totals approximately 2.53 acres of RS-7.2 zoned property located in the southwestern portion of Federal Way, with a Comprehensive Plan designation of Single Family, High Density. The project proposes a short plat consisting of seven (7) single-family lots, averaging approximately 7,700 square feet, with a storm water tract, an open space/tree retention tract, a joint -use driveway easement and Right -of -Way (ROW) dedications. The following is a general project narrative that outlines the proposal as well as known issues and constraints that are relevant to this project: SW 344h Place ROW ❑edication The prior development to the south (Danville Station Division 1) constructed SW 344`h Place as a 'I street, dedicating 30' of right-of-way and constructing a sidewalk, landscape strip, curb and gutter with 20' of pavement on the south side of the roadway. This project proposes to dedicate 22' of right -of way on the north side of the road to complete a modified Type "W" right-of-way with improvements. SW 344P Street ROW Modification The project proposes a 13' right-of-way dedication from the northerly portion of the property, for the future construction of the SW 344th Street through -way. The roadway has been identified as a Type K street with a full right-of-way of 78 feet. The adjacent property to the north is also undeveloped, and we anticipate their ROW dedication will complete the width required should future development occur at that -property.

Stormwater This project proposes a stormwater facility located on the west of the property where drainage would naturally occur from roof and driveway runoff. The soils on this property do not have a great amount of infiltration, so the size of the stormwater is exceptional, reducing the space available for another lot from what was originally anticipated. The facilities have been sized according to the 2016 King County Surface Water Design Manual for Level 3 Flow Control and Basic Water Quality. There is an existing stormwater pond located to the southwest of the site that is spaced to accommodate the runoff from the right-of-way improvements proposed with this project. Please review the included Preliminary Technical Information Report for further details. Critical Areas Based on City maps and public GIS information, there was an historic wetland adjacent to the northwest corner of the site on the WSDOT property. Upon evaluation from a certified Wetland Biologist, and discussion with WSDOTs consultants, there is no evidence of a wetland or any other critical areas at this location or adjacent to the property. Please refer to the Critical Areas Assessment prepared by Habitat Technologies. Open Space Requirements According to the requirements of the RS-7.2 zone, a minimum of 15% of the gross land area of the property shall be open space. Due to the limited amount of developable area of the property, this requirement would have a significant impact on the number of lots proposed. We understand the City of Federal Way allows developments to pay a fee in lieu of providing all or a portion of this open space requirement, at the discretion of the Parks Director.

LD. 78517 k CITY OF Federal Way Exhibit A Findings of Facts Pena Short Plat, Phase II, File # 17-106104-00-SU The Planning Division hereby makes the following Findings of Facts pursuant to content requirements of the Short Subdivision decision as set forth in Federal Way Revised Cade (FWRC) 18.30.110. These facts are in reference to King County tax parcel number 242103-9018, located at SW 344,h Street and 161" Avenue SW, Federal Way. 1. Proposal —The applicant proposes to subdivide one existing 110,331 square -foot (2.53-acre) single- family Iot into eight single-family residential lots and one stormwater tract. As shown on the short plat, the following are the net square footage for each lot/tract: Lot 1 7,230 sq. ft. Lot 6 7,360 sq. ft. Lot 2 7,240 sq. ft. 7,790 sq. ft. (net) Lot 3 7,240 sq. ft. Lot 7 7,250 sq. ft. Lot 4 7,250 sq. ft. 8,620 sq. ft. (net) Lot 5 7,250 sq. ft. Lot 8 8,290 sq. ft. Tract A 11,970 sq. ft. 2. Review Process — Pursuant to FWRC Chapter 18.30 `Short Subdivision Plats,' the proposed short plat is subject to administrative review and decision rendered by the Director of Community Development. The proposal has been reviewed by staff from the Departments of Community Development and Public Works, Lakehaven Water & Sewer, and South King Fire and Rescue. City staff used the following FWRC development regulations when reviewing the short subdivision application: Title 16 `Surface Water Management;' Title 18 `Subdivisions;' and Title 19, `Zoning and Development Code.' 3. Site Profile — The subject property is located at SW 344th Place and 16t" Avenue SW. The 2.53- acre parcel is rectangular in shape and is currently vacant with dense stands of deciduous and coniferous trees with a moderate to dense understory of native and invasive plants. The site gently slopes from east to west at about three to four percent. 4. Comprehensive Plan —The subject property's comprehensive plan designation is Single - Family — High -Density Residential. The proposal provides all urban density consistent with the Federal Way Comprehensive Plan (FWCP) designation. The proposal meets relevant goals and policies of the FWCP. 5. Density and Dimensions — The subject property is located within a Single -Family Residential (RS 7.2) zone with a minimum lot size requirement of 7,200 square feet. The proposal meets the density requirement as noted above. FWRC 19.200.010 "Detached Dwelling Unit", prescribes setbacks, height, parking, and lot coverage requirements. The proposed site plan depicts meeting the 20-foot front, 5-foot side, and 5-foot rear setbacks required by code. Lot 8 is a flag lot; the front yard setback is accurately depicted. Future building permit applications will be reviewed for compliance with these provisions. 6. State Environmental Policy Act (SEPA) —The eight -lot short plat is exempt from environmental review pursuant to Washington Administrative Code (WAC) 197-11-800(6)(d). 7. Public Notice & Comment —A Notice of Land Use Application for the short subdivision was published in the Federal Way Mirror and posted at the subject property and city designated notice boards on February 2, 2018. No comments were received during the public comment period. S. Environmentally Critical Areas — The City's Critical Areas Map shows wetlands and a stream adjacent to the northwest corner of the subject property on a parcel owned by King County Transit. Per FWRC 19.145.410(2), a wetland report prepared by a qualified professional is required for any development within 225 feet of a wetland. The applicant submitted a Critical Areas Assessment, prepared by Habitat Technologies, dated October 25, 2017. Per the assessment, no portion of the project site exhibited the required criteria for designation as a "wetland" and that no portion of the project site exhibited field indicators associated with a "stream". There is a regional drainage corridor offsite to the northwest of the northwestern corner of the project site. This offsite drainage corridor appears to be best defined as an artificial watercourse intentionally created to address regional stormwater concerns and management. Based on conversations the applicant's wetland biologist has had with the Washington State Department of Transportation (WSDOT), owner of the property to the north, the area supported hydrophytic vegetation, but it did not meet hydric soil criteria. Two stony water features, classified as stormwater ditches, intersect the WSDOT parcel and do not meet jurisdictional wetland or stream criteria. No portion of the site was identified to provide critical habitat for federally- or state -listed endangered, threatened, or sensitive species; to provide state -listed priority habitats; or to provide habitats for species of local importance. The City's stream and wetland consultant, Otak, provided peer review of the report. Otak provided a technical memorandum, dated May 22, 2018, which concurs with Habitat Technologies report concluding that no critical areas occurs on the subject property. Also, the off -site drainage feature to the north and northwest of the subject property appears to have been artificially created in uplands and would be exempt per FWRC 19.145.110(3). Otak recommended that the off -site wetland to the north of the property be rated to determine buffer width as the buffer may extend onto the subject property. Based on information that was provided by WSDOT and Habitat Technologies, the city concurs that the off -site feature is drainage and not a regulated wetland. No additional evaluation is needed. 9. Open Space — As the City continues to grow with each new development and increase in residents, the demand for additional recreational areas will follow. Providing open space with the new development is necessary to address the recreation needs of the growing community. As part of the City's 2013 Parks, Recreation, and Open Space Plan ("the Plan"), the City has adopted the following core values, goals, and policies regarding recreation and open space: Core Value #3: Retain and Improve Our Open Space. Open spaces and natural areas in the City provide an array of benefits to people and wildlife and can contribute to enhancing water quality in the community. Findings of Facts Page 2 Pena Short Plat, Phase II 17-106104-SU/Doc. I.D. 78516 Core Value #5: Provide a Balance of Services for a Diverse Population. Understanding the population being served and providing programs and opportunities that reflect residents' needs and interests is a major goal of the Plan. Federal Way's park system should provide a variety of options for active and passive recreation opportunities. Goal B.1: Improve and maintain all neighborhood parks to maximize safety, visibility, usability, appeal, and identity. Policy 13.2: Plan for improvements to neighborhood parks based on their unique potential and designated role in the City-wide system. Policy B.3: Explore ways to allow for informal play opportunities by incorporating unprogrammed spaces such as fields and forested areas. Goal C.1: Maintain City parks and open spaces so that they are inviting to users and offer facilities and activities based on the potential of each property and community need. Policy C.1: Develop a more recognizable and inviting park and open space system. Goal L.1: Manage environmentally sensitive lands for long-term ecosystem health and biodiversity of natural systems, while making them accessible to the community. Policy L.1: Maintain open spaces so that they are accessible to residents. Goal N.1: Preserve privately -owned open spaces with environmental constraints through incentive -based programs to provide `breathing -room' open space. Policy N.3: To gain maximum effect on overall parks and recreation system, audit and revise City code requirements for on -site open space, and revise to require contribution to larger parks system rather than small, on -site parcels. As proposed, the added residents in the 8-lot short plat will increase the demand for recreation activities and usable open space. Pursuant to FWRC 18.55.060, in order to reasonably mitigate the impact of development, the applicant is required to provide open space in the amount of 15 percent of the gross land area of the property. As proposed, there is limited space to provide on - site open space and the applicant has requested that a fee -in -lieu of open space be permissible. The Parks Department has agreed to allow the applicant to pay a fee -in -lieu of open space as allowed by FWRC 18.55.060(2). Prior to plat recording, the applicant will be required to pay 15 percent of the most recent assessed land value of the subject property pursuant to limitations set forth in FWRC 19.100.070(1). The Parks Department would ask that consideration be given to provide a voluntary letter authorizing the City of Federal Way to use the open space fee -in -lieu from the Pena Short Plat in any of the Parks Planning Areas pursuant to FWRC 18.55.060(2). 10. Tree and Vegetation Retention/Replacement —Per FWRC 19.120.130(2), single-family residential zones are required to maintain a minimum of 25 tree units per acre. The total amount of tree units required for the short subdivision is calculated by multiplying gross site acreage, minus any proposed public/private street by the required tree density per FWRC 19.120.130(3). Per the engineering drawing plan, the gross acreage of the site is 2.53 acres and the right-of-way dedication is 0.86 acres, for a net total of 1.67 acres. The subject property requires 42 tree units (1.67 acres multiplied by 25 tree units per acre). The applicant proposes to remove all existing trees and replace the required 42 tree units. Findings of Facts Page 3 Pena Short Plat, Phase II 17-106104-SU/Doc. I.D. 78516 If all the trees are removed from the property a Class IV -General Forest Practices Permit may be required, see below for more information. 11. Forest Practice — A Class IV - General Forest Practices application must be submitted to the City whenever more than 5,000 board feet of merchantable timber is harvested from the property pursuant to FWRC Article IV, Forest Practices Regulations. This is approximately equal to one log truck of timber. A Class IV -General Forest Practices is not exempt from SEPA review. A completed environmental checklist must be submitted with the Forest Practice application for review. Per FWRC Chapter 14.10, the public, government agencies, and tribes will be invited to comment on the checklist during a 14-day comment period. An environmental threshold determination made by the director must be rendered prior to approval of the Forest Practices Application. Once approved, a copy of the forest practices application will be routed to the Washington State Department of Revenue (DOR), as forest practices are subject to forest excise tax at the time of harvest. 12. Concurrency — The City's Traffic Division reviewed the applicant's concurrency application and concludes the proposed short subdivision will generate 10 new PM peak hour trips. Traffic Division staff have determined that all intersections impacted by one or more weekday evening peak hour trips from the proposed development would meet the level of service (LOS) standards with programmed improvements; therefore, a Capacity Reserve Certificate was issued February 23, 2018. 13. Transportation Impact Fee — In order to mitigate the impacts of new development on the City's street infrastructure, the applicant will be subject to the transportation impact fee (TIF). The fee will be assessed and collected from the applicant when the building permits are issued, using the fee schedule then in effect. 14. Street Frontage Improvements — The applicant is required to dedicate right-of-way (ROW) and provide street frontage improvements along SW 344"' Street, SW 344"' Place, and 18"' Avenue SW. A modified Type "W" street, consisting of a 22-foot ROW dedication and half street improvements including curb, gutter, planter strip with street trees, streetlight, sidewalk are proposed on SW 3441h Place. The Comprehensive Plan, Map III 4 depicted a 3-lane east -west principal collector road extending from 18"' Ave SW to 15"' PI SW. The applicant is to dedicate ROW and construct improvements for the portion of the road extension abutting and within the subject property to a Type "K" street. The applicant submitted a request to modify the required ROW width and improvements for SW 344th Street. The City issued a street modification on July 25, 2018, requiring a 39-foot ROW dedication along SW 344"' Street and granted a waiver of all frontage improvements. 15. Access —Lots 1-6 will access directly off SW 344"' Place. No access is allowed on SW 344"' Street. Lots 7-8 will be accessed via a 20-foot access and utility easement. 16. Stormwater — The project is required to meet flow control and water quality standards outlined in the 2016 King County Surface Water Design Manual and the Federal Way Addendum. Review of engineering plans and the TIR will continue under a separate Engineering (EN) application. An EN review fee and application must be submitted at this time. When submitting for EN review, the applicant shall either: Findings of Facts Page 4 Pena Short Plat, Phase II 17-106104-SU/Doc. I.D. 78516 a) Route the detention pond discharge so that it bypasses the existing infiltration facility, or provide infiltration testing and mitigation to assure original infiltration rates are maintained, or b) Provide geotechnical review of the effect groundwater will have on the detention pond, and whether or not a pond liner will be needed. 17. Schools — As part of the City's initial review of the proposal, the short plat application was routed to the Federal Way School District for comments. Comments from the school district indicate Sherwood Forest Elementary, Illahee Middle School, and Todd Beamer High School service the area. Students living in the area receive school bus transportation to Illahee Middle School and Todd Beamer High School. Students would walk to Sherwood Forest Elementary. The applicant provided a School Access Analysis which was forwarded to the School District. The school access analysis identifies a safe path of travel for students walking to and from school and to the bus stop. Final location and design of the school access route shall be approved by the Federal Way School District prior to issuance of construction pen -nits for infrastructure improvements. A school impact fee is required to mitigate the additional new students this subdivision may add. The school impact fee is due at the time of building permit issuance for new dwelling units. This fee amount is subject to change and is determined annually by the Federal Way School District. 18. Water and Sewer — The applicant proposes to serve the short subdivision with a public water supply and distribution system managed by Lakehaven Water & Sewer. The September 29, 2017, Certificate of Water Availability indicates Lakehaven's capacity to serve the proposed development by a service connection to an existing 8" diameter water main that is approximately 10+/- feet from the site. The applicant proposes to serve the short subdivision by a public sewer system managed by Lakehaven Water & Sewer (Lakehaven). A September 29, 2017, Certificate of Sewer Availability indicates the district's capacity to serve the proposed development will require a service connection to an existing 8" diameter sewer main that is approximately 15+/- feet from the site. There are eight existing sewer service stubs on the property. 19. Fire Requirements — South King Fire and Rescue has indicated that a Certificate of Water Availability which includes a hydraulic fire flow model, shall be requested from the Lakehaven and provided at the time of building permit application for each lot. Lot 8 will require fire sprinklers due to access. Remaining fire sprinkler requirements, if any, will be determined at the time of building pen -nit application review for each lot. A note regarding sprinkler requirement for Lot 8 must be added to the short plat drawing prior to recording. 20. Lot Addresses — Prior to recording, addresses for each lot must be put on the short plat drawing. The City will assign address numbers and provide them under separate cover. 21. Conditions of Approval — Staff recommends the Director of Community Development include the following conditions of approval in the short subdivision decision. Unless otherwise permitted in FWRC 18.30.280, all conditions shall be met prior to plat recording: 1) The applicant must obtain Engineering (EN) approval and authorization to proceed from the Public Works Department prior to construction of plat infrastructure. 2) Prior to engineering plan approval, the applicant shall either: Findings of Facts Page 5 Pefia Short Plat, Phase II 17-106104-SU/Doc.

The approximate site location is shown on the Site Location Map, included as Figure 1. Our understanding of the project is based on our conversations with Ms. Savanna Nagorski of ESM Consulting Engineers, our review of the site plan provided to us, and our experience in the Federal Way area. We understand that you propose to construct an 8 lot residential plat at the site which will be Phase II to the already completed 7 lot Phase I located on the same street. We anticipate that the new residences will likely be one or two story, wood framed structures with conventional shallow foundations. Additional development will likely include driveways, a stormwater facility, the completion of Southwest 344th street, and typical underground utilities. SCOPE The purpose of our services is to evaluate the surface and subsurface conditions across the site as a basis for providing geotechnical recommendations and conclusions for the proposed development. Specifically, the scope of services for this project included the following: 1. Reviewing the available geologic, hydrogeologic, and geotechnical data for the site area; 2. Exploring subsurface conditions across the site by excavating a series of test pits at select locations across the site; 3. Describing surface and subsurface conditions, including soil type, depth to groundwater, and an estimate of seasonal high groundwater levels; Pena.SW344thSt.RG November 20, 2017 page 12 4. Providing geotechnical conclusions and recommendations regarding site grading activities, including site preparation, subgrade preparation, fill placement criteria, suitability of on -site soils for use as structural fill, temporary and permanent cut slopes and drainage and erosion control measures; 5. Providing conclusions regarding shallow foundations, deep foundations, and floor slab support and design criteria, including bearing capacity and subgrade modulus as appropriate; 6. Providing our opinion about the feasibility of onsite infiltration, including a preliminary design infiltration rate based on grain size data, as applicable; 7. Providing recommendations for erosion and sediment control during wet weather grading and construction; 8. Preparing a written Geotechnical and Design Report summarizing our site observations and conclusions, and our geotechnical recommendations and design criteria, along with the supporting data. The above scope of work was summarized in our Proposal for Geotechnical Engineering Services dated August 8, 2017. We received written authorization to proceed from you on September 18, 2017. SITE CONDITIONS Surface Conditions The site is located at Southwest 344th Street in Federal Way, Washington (PN: 2421039018), within an area of existing residential development. The site is rectangular in shape, measures approximately 165 feet deep (north to south) by 670 feet wide (east to west), and encompasses about 2.53 acres. The site is bounded by undeveloped land to the north, Southwest 344th Place to the south, 18th Avenue Southwest to the west, and residential development to the east. The site is gently slopes from east to west at about 3 to 4 percent. Total topographic relief across the site is on the order of 23 feet. The parcel is undeveloped. The existing site topography is shown on the Site and Exploration Plan, included as Figure 2. Vegetation across the site consists of a dense stand of deciduous and coniferous trees with a moderate to dense understory of native and invasive plants. No evidence of erosion or slope movement was observed at the site at the time of our site visit. Site Soils The USDA Natural Resource Conservation Survey (NRCS) Web Soil Survey maps the site as being underlain by Alderwood gravelly sandy loam. The Alderwood soils are typically derived from glacial till, form on slopes of 0 to 8 percent, are listed as having a "slight' erosion hazard when exposed, and are included in hydrologic soils group C. An excerpt from the NRCS soils map for the site area is included as Figure 3. Site Geology The Geologic Map of the Poverty Bay 7.5-Minute Quadrangle, Washington (Haugerud and Barnett, 2003) maps the site and the adjacent areas as being underlain by glacial till (Qvt). These glacial soils were deposited during the Vashon stade of the Frasier Glaciation. The glacial till generally consists of a heterogeneous mixture of gravel, sand, silt, and clay that was deposited at the base of the GEORESOURCES Pena.SW344thSt.RG November 20, 2017 page 13 advancing continental ice mass, and was subsequently overridden. As such, it is considered to be over consolidated, and generally has high strength and low compressibility characteristics where undisturbed. No areas of landslide deposits or mass wasting are mapped within the immediate vicinity of the site. An excerpt of the above referenced map is included as Figure 4. Subsurface Explorations On October 24, 2017, we submitted a request for administrative decision to the City of Federal Way to perform explorations within a critical area buffer. We received approval of our request on November 7, 2017. On November 15, 2017, a field engineer from GeoResources, LLC (GeoResources) was on site and monitored the excavation of five test pits to depths of about 3.5 to 6.0 feet below the existing ground surface, logged the subsurface conditions encountered in each test pit, and obtained representative soil samples. The test pits were excavated by a small track -mounted excavator operated by a licensed operated working under subcontract for us. The number and location of the test pits were selected in the field based on project information provided by you, our understanding of the proposed development, consideration for underground utilities, existing site conditions, and current site usage. Each test pit was then backfilled with the excavated soils and bucket tamped, but not otherwise compacted. The subsurface explorations excavated as part of this evaluation indicate the subsurface conditions at specific locations only, as actual subsurface conditions can vary across the site. Furthermore, the nature and extent of such variation would not become evident until additional explorations are performed or until construction activities have begun. Based on our experience in the area and extent of prior explorations in the area, it is our opinion that the soils encountered in the explorations are generally representative of the soils at the site. Subsurface Conditions Our test pits encountered somewhat variable subsurface conditions that generally confirmed the mapped stratigraphy at the site. In general, we encountered about 0.5 to 1 foot of topsoil mantling 2 to 5 feet of brown to tan, orange stained silty sand to silty sand with gravel. The gravel fraction appeared to increase with depth. We interpret these shallow soils to be weathered glacial till that appeared to be in a loose to medium dense, moist condition. Below the surficial soils, our explorations encoutnered tan to tan and grey silty sand with gravel in a dense to very dense, moist condition to the full depth explored. We interpret these deeper soils to be consistent with glacial till. Laboratory Testing Geotechnical laboratory tests were performed on select samples retrieved from the borings to determine soil index and engineering properties encountered. Laboratory testing included visual soil classification per ASTM D: 2488, moisture content determinations per ASTM D: 2216, and grain size analyses per ASTM D: 422 standard procedures. The results of the laboratory tests are included in Appendix B. Groundwater Conditions Mottling and orange oxide staining was observed at 1.5 to 2.75 feet below the existing ground surface. These characteristics are generally indicative of a seasonal perched groundwater table, which GEORESOURCES Pena.SW344thSt.RG November 20, 2017 page 14 generally develops when a higher permeability soil, such as weathered till, is underlain by a lower permeability soil, such as undisturbed glacial till. No groundwater seepage was observed in our explorations at the time of excavation. We anticipate fluctuations in the local groundwater levels will occur in response to precipitation patterns, off -site construction activities, and site utilization. ENGINEERING CONCLUSIONS AND RECOMMENDATIONS Based on the results of our data review, site reconnaissance, subsurface explorations and our experience in the area, it is our opinion that the site should be suitable for the proposed residential development, provided the geotechnical recommendations regarding the design and construction of the proposed development are contained in this report are included in the project plans and specifications. A detailed discussion of our conclusions follows. Seismic Hazards Based on our observation and the subsurface units mapped at the site, we interpret the structural site conditions to correspond to a seismic Site Class "D" in accordance with the 2015 International Building Code (IBC), Section 1613.3.2 and ASCE 7-10, Chapter 20, Section 20.3-1. This is based on the likely range of equivalent SPT (Standard Penetration Test) blow counts for the soil types observed in the site area. These conditions were assumed to be representative for the conditions based on our experience in the vicinity of the site. These soils are not prone to liquefaction and do not constitute a seismic hazard area. Liquefaction is a phenomenon where there is a reduction or complete loss of soil strength due to an increase in pore water pressure. The increase in pore water pressure is induced by seismic vibrations. Liquefaction mainly affects geologically recent deposits of loose, fine-grained sands that are below the groundwater table. Based on the gradation of the soils encountered in our hand auger explorations, it is our opinion that the risk for liquefaction to occur at this site during an earthquake is negligible. Provided the design criteria listed below are followed, the proposed structure should have no greater seismic risk damage than other appropriately designed structures in the Puget Sound area. Foundation Support We recommend that spread footings for any new structures be founded on the medium dense weathered till soils, the very dense glacial till soils, or on structural fill that extends to suitable native soils. The native soil at the base of the excavations should be disturbed as little as possible. All loose, soft or unsuitable material should be removed and replaced or recompacted, as appropriate. All footing elements should be embedded at least 18 inches below grade for frost protection. We recommend a minimum width of 2 feet for isolated footings and at least 16 inches for continuous wall footings. Footings founded as described above on the structural fill or weathered till may be designed with a maximum allowable bearing pressure of 2,500 psf (pounds per square foot), while foundations that bear directly on the deeper unweathered glacial till can be designed for maximum allowable bearing pressure of 3,500 psf. Both values are for combined dead and long- term live loads. The weight of the footing and any overlying backfill may be neglected. The GEORESOURC -5 Pena.SW344thSt.RG November 20, 2017 page 15 allowable bearing value may be increased by one-third for transient loads such as those induced by seismic events or wind loads. Lateral loads may be resisted by friction on the base of footings and floor slabs and as passive pressure on the sides of footings, provided the footings are prepared as described above. We recommend that an allowable coefficient of friction of 0.35 be used to calculate friction between the concrete and the underlying soil. Passive pressure may be determined using an allowable equivalent fluid density of 350 pcf. Factors of safety have been applied to these values. We estimate that total settlements of footings designed and constructed as recommended will be less than 1 inch over a 50-foot length for the anticipated load conditions, with differential settlements between comparably loaded footings of Yz inch or less. Typical building settlements within granular soils occur essentially as loads are being applied; however, because of the fines content of the site soils, the estimated settlements could occur over a longer time. Disturbance of the foundation subgrade during construction could result in larger settlements than predicted. Floor Slab Support We anticipate that any garage areas will consist of a slab -on -grade floors that should be supported on the native soils or on structural fill prepared as described above. Although not encountered in our explorations, any areas of old fill material should be evaluated during grading activity for suitability of structural support. Areas of significant organic debris should be removed. We recommend that floor slabs be directly underlain by a minimum 4-inch thick pea gravel or clean crushed rock with less than 2 percent fines. This layer should be placed in one lift and compacted to an unyielding condition. A synthetic vapor retarder is recommended to control moisture migration through the slabs. This is of particular importance where the slab is underlain by the dense glacial till, or where moisture migration through the slab is an issue, such as where adhesives are used to anchor carpet or tile to the slab. A subgrade modulus of 350 kcf (kips per cubic foot) may be used for floor slab design. We estimate that settlement of the floor slabs designed and constructed as recommended, will be �/2 inch or less over a span of 50 feet. Temporary Excavations All job site safety issues and precautions are the responsibility of the contractor providing services/work. The following cut/fill slope guidelines are provided for planning purposes only. Temporary cut slopes will likely be necessary during grading operations or utility installation. All excavations at the site associated with confined spaces, such as utility trenches and retaining walls, must be completed in accordance with local, state, or federal requirements. Based on current Washington State Safety and Health Administration (WSHA) regulations, the upper silty material, weathered till would be classified as Type C soils, whereas the deeper glacial till and dense silt soils would be classified as Type A soils. According to WSHA, for temporary excavations of less than 20 feet in depth, the side slopes in Type A soils should be laid back at a slope inclination of 0.75H:1V (Horizontal: Vertical) or flatter from the toe to the crest of the slope whereas the upper Type C soils should be sloped at a maximum inclination of 1.5HIV. All exposed slope faces should be covered with a durable reinforced plastic membrane during construction to prevent slope raveling and rutting during periods of precipitation. These guidelines assume that all surface loads are kept at a minimum GEORESOURCES Pena.SW344thSt.RG November 20, 2017 page 16 distance of at least one half the depth of the cut away from the top of the slope and that significant seepage is not present on the slope face. Flatter cut slopes will be necessary where significant raveling or seepage occurs, or if construction materials will be stockpiled along the slope crest. Where it is not feasible to slope the site soils back at these inclinations, a retaining structure should be considered. Where retaining structures are greater than 4-feet in height (bottom of footing to top of structure) or have slopes of greater than 15 percent above them, they should be engineered per Washington Administrative Code (WAC 51-16-080 item 5). This information is provided solely for the benefit of the owner and other design consultants, and should not be construed to imply that GeoResources assumes responsibility for job site safety. It is understood thatjob site safety is the sole responsibility of the project contractor. Site Drainage All ground surfaces, pavements and sidewalks at the site should be sloped away from the structures. Surface water runoff should be controlled by a system of curbs, berms, drainage swales, and or catch basins, and conveyed to an appropriate discharge point. We recommend that footing drains are installed for the residences in accordance with 2015 IBC 1807.4.2, and basement walls (if utilized) have a wall drain as describe above. The roof drain should not be connected to the footing drain. Stormwater Infiltration We understand that the City of Federal Way uses the 2016 King County Surface Water Design Manual (KCSWDM) for stormwater management. In accordance with Section 5.2 of the 2016 KCSWDM, a minimum separation of 3 feet between the bottom of an infiltration facility and the top of a seasonal high groundwater table or other impermeable layer is required. Evidence of seasonal high groundwater was observed at 1.5 to 2.75 feet below the existing ground surface; therefore, onsite infiltration of stormwater runoff generated by the proposed development is not feasible in accordance with the 2016 KCSWDM. Alternative stormwater management methods should be considered for this project. Stormwater facilities should be designed and constructed in accordance with the 2016 KCSWDM. All infeasibility criteria and minimum setbacks should be considered prior to the selection of a stormwater management method. EARTHWORK RECOMMENDATIONS Site Preparation All structural areas on the site to be graded should be stripped of vegetation, organic surface soils, and other deleterious materials including existing structures, foundations or abandoned utility lines. Organic topsoil is not suitable for use as structural fill, but may be used for limited depths in non-structural areas. Stripping depths ranging from 6 to 12 inches should be expected to remove these unsuitable soils. Areas of thicker topsoil or organic debris may be encountered in areas of heavy vegetation or depressions. Where placement of fill material is required, the stripped/exposed subgrade areas should be compacted to a firm and unyielding surface prior to placement of any fill. Excavations for debris removal should be backfilled with structural fill compacted to the densities described in the "Structural Fill" section of this report. GEORESOURCES Pena.SW344th5t.RG November 20, 2017 Page 17 We recommend that a member of our staff evaluate the exposed subgrade conditions after removal of vegetation and topsoil stripping is completed and prior to placement of structural fill. The exposed subgrade soil should be proof -rolled with heavy rubber -tired equipment during dry weather or probed with a 1/2-inch-diameter steel rod during wet weather conditions. Soft, loose or otherwise unsuitable areas delineated during proofrolling or probing should be recompacted, if practical, or over -excavated and replaced with structural fill. The depth and extent of over excavation should be evaluated by our field representative at the time of construction. The areas of old fill material should be evaluated during grading operations to determine if they need mitigation, recompaction, or removal. Structural Fill All material placed as fill associated with mass grading, as utility trench backfill, under building areas, or under roadways should be placed as structural fill. The structural fill should be placed in horizontal lifts of appropriate thickness to allow adequate and uniform compaction of each lift. Structural fill should be compacted to at least 95 percent of MDD (maximum dry density as determined in accordance with ASTM D-1557). The appropriate lift thickness will depend on the structural fill characteristics and compaction equipment used. We recommend that the appropriate lift thickness be evaluated by our field representative during construction. We recommend that our representative be present during site grading activities to observe the work and perform field density tests. The suitability of material for use as structural fill will depend on the gradation and moisture content of the soil. As the amount of fines (material passing US No. 200 sieve) increases, soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult to achieve. During wet weather, we recommend use of well -graded sand and gravel with less than 5 percent (by weight) passing the US No. 200 sieve based on that fraction passing the 3/4-inch sieve, such as Gravel Backfill for Walls (WSDOT 9-03.12(2)). If prolonged dry weather prevails during the earthwork and foundation installation phase of construction, higher fines content (up to 10 to 12 percent) may be acceptable. Material placed for structural fill should be free of debris, organic matter, trash, and cobbles greater than 6-inches in diameter. The moisture content of the fill material should be adjusted as necessary for proper compaction. Suitability of On -Site Materials as Fill During dry weather construction, any nonorganic onsite soil may be considered for use as structural fill, provided it meets the criteria described above in the "Structural Fill" section and can be compacted as recommended. If the moisture content of the soil is over optimum when excavated, it will be necessary to aerate or dry the soil prior to placement as structural fill. The native weathered till and glacial till soils generally consisted of silty sand with gravel. These soils are generally comparable to common borrow (WSDOT 9-03.14(3)) and are suitable for use as structural fill provided the moisture content is maintained within 2 percent of the optimum moisture level. However, these soils may become difficult to adequately compact during extended periods of wet weather or where seepage occurs. We recommend that completed graded areas be restricted from traffic or protected prior to wet weather conditions. The graded areas may be protected by paving, placing asphalt -treated GEORESOURCES Pena.SW344thSt.RG November 20, 2017 page 18 base, a layer of free -draining material such as pit run sand and gravel or clean crushed rock material containing less than 5 percent fines, or some combination of the above. Erosion Control Weathering, erosion and the resulting surficial sloughing and shallow land sliding are natural processes. As noted, no evidence of surficial raveling or sloughing was observed at the site. To manage and reduce the potential for these natural processes, we recommend erosion protection measures will need to be in place prior to grading activity on the site. Erosion hazards can be mitigated by applying BMPs outlined in the 2016 King County Surface Water Design Manual. Wet Weather Earthwork Considerations In the Puget Sound area, wet weather generally begins about mid -October and continues through about May, although rainy periods could occur at any time of year. Therefore, it is strongly encouraged that earthwork be scheduled during the dry weather months of June through September. Most of the soil at the site contains sufficient fines to produce an unstable mixture when wet. Such soil is highly susceptible to changes in water content and tends to become unstable and impossible to proof -roll and compact if the moisture content exceeds the optimum. In addition, during wet weather months, the groundwater levels could increase, resulting in seepage into site excavations. Performing earthwork during dry weather would reduce these problems and costs associated with rainwater, construction traffic, and handling of wet soil. However, should wet weather/wet condition earthwork be unavoidable, the following recommendations are provided: • The ground surface in and surrounding the construction area should be sloped as much as possible to promote runoff of precipitation away from work areas and to prevent ponding of water. • Work areas or slopes should be covered with plastic. The use of sloping, ditching, sumps, dewatering, and other measures should be employed as necessary to permit proper completion of the work. • Earthwork should be accomplished in small sections to minimize exposure to wet conditions. That is, each section should be small enough so that the removal of unsuitable soils and placement and compaction of clean structural fill could be accomplished on the same day. The size of construction equipment may have to be limited to prevent soil disturbance. It may be necessary to excavate soils with a backhoe, or equivalent, and locate them so that equipment does not pass over the excavated area. Thus, subgrade disturbance caused by equipment traffic would be minimized. • Fill material should consist of clean, well -graded, sand and gravel, of which not more than 5 percent fines by dry weight passes the No. 200 mesh sieve, based on wet -sieving the fraction passing the 3/-inch mesh sieve. The gravel content should range from between 20 and 50 percent retained on a No. 4 mesh sieve. The fines should be non -plastic. No exposed soil should be left uncompacted and exposed to moisture. A smooth -drum vibratory roller, or equivalent, should roll the surface to seal out as much water as possible. ■ In -place soil or fill soil that becomes wet and unstable and/or too wet to suitably compact should be removed and replaced with clean, granular soil (see gradation requirements above). GEORESOURCES Pena.SW344thSt.RG November 20, 2017 Page 19 Excavation and placement of structural fill material should be observed on a full-time basis by a geotechnical engineer (or representative) experienced in wet weather/wet condition earthwork to determine that all work is being accomplished in accordance with the project specifications and our recommendations. Grading and earthwork should not be accomplished during periods of heavy, continuous rainfall. We recommend that the above requirements for wet weather/wet condition earthwork be incorporated into the contract specifications. Construction Observation We recommend that GeoResources, LLC be retained to observe the geotechnical aspects of construction including stripping, foundations, fill placement and compaction, and drainage activities. This observation would allow us to verify the subsurface conditions as they are exposed during construction and to determine that work is accomplished in accordance with our recommendations. If conditions encountered during construction differ from those anticipated, we can provide recommendations for the conditions actually encountered. LIMITATIONS We have prepared this report for use by the Pena's and other members of the design team, for use in the design of a portion of this project. The data used in preparing this report and this report should be provided to prospective contractors for their bidding or estimating purposes only. Our report, conclusions and interpretations are based on our subsurface explorations, data from others and limited site reconnaissance, and should not be construed as a warranty of the subsurface conditions. Variations in subsurface conditions are possible between the explorations and may also occur with time. A contingency for unanticipated conditions should be included in the budget and schedule. Sufficient monitoring, testing and consultation should be provided by our firm during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether earthwork and foundation installation activities comply with contract plans and specifications. The scope of our services does not include services related to environmental remediation and construction safety precautions. Our recommendations are not intended to direct the contractor's methods, techniques, sequences or procedures, except as specifically described in our report for consideration in design. If there are any changes in the loads, grades, locations, configurations or type of facilities to be constructed, the conclusions and recommendations presented in this report may not be fully applicable. If such changes are made, we should be given the opportunity to review our recommendations and provide written modifications or verifications, as appropriate.

The project site was vacant and located within an area dominated by existing single-family homesites that were well served by public roadways and utilities. The onsite assessment and evaluation of critical areas within and immediately adjacent to the project site was completed following the methods and procedures defined in the Corps of Engineers Wetland Delineation Manual (United States Army Corps of Engineers, 1987) with the Regional Supplement to the Corps of Engineers Wetland Delineation Manual. Western Mountains, Valleys, and Coast Region (United States Army Corps of Engineers, 2010); the Washington State Wetland Rating System for Western Washington: 2014 Update Publication #14-06-029 (Hruby, 2014), the State of Washington Department of Natural Resources (WDNR) Forest Practice Rules (WAC 222-16-030), and the City of Federal Way Title 19.145 — Environmentally Critical Areas. The evaluation and characterization of onsite and adjacent critical areas (i.e. wetlands, surface water drainages, critical fish and wildlife habitats) is a vital element in land use planning. The goal of this approach is to ensure that present and proposed planned site development, to include the establishment of protective buffers, does not result in adverse environmental impacts to identified wetlands or other critical areas. PROJECT SITE DESCRIPTION The project site was vacant, rectangular in shape, approximately 2.5-acres in total size, and located within a well urbanized residential area that was well served by public roadways and utilities. The project exhibited a gentle slope generally from the southeast to the northwest. The project site had undergone prior forest harvest and vegetation clearing actions and was dominated by a deciduous forest plant community. A utility corridor was present along the northern boundary of the project site and a stormwater discharge culvert was present near the north -central boundary of the project site. From the stormwater discharge culvert, seasonal stormwater runoff continued to the west within a created ditch and eventually exited offsite to the northwest at the northwestern corner of the project site. From the northwestern corner of the project site seasonal surface water runoff appeared to enter a regional stormwater drainage that directed seasonal surface water to the north along the eastern boundary of the Twin Lakes Park and Ride facility offsite to the northwest. Directions to Project Site: From the intersection of Pacific Highway and SW 320th Street within the City of Federal Way continue west on SW 320th Street to 21st Avenue SE. Turn south onto 21 st Avenue SE and continue to SW 344th Street. Turn east onto SW 344th Street and continue to project site located east of the intersection of SW 344th Street and 18th Avenue SW. 1 17177 BACKGROUND INFORMATION NATIONAL WETLAND INVENTORY The National Wetland Inventory (NWI) mapping completed by the U.S. Fish and Wildlife Service was reviewed as a part of this assessment (Figure 2). This mapping resource did not identify any wetlands or surface water drainages within or immediately adjacent to the project site. STATE OF WASHINGTON PRIORITY HABITATS AND SPECIES The State of Washington Priority Habitats and Species (PHS) Mapping was reviewed as a part of this assessment (Figure 3). This mapping resource did not identify any wetland or drainage corridors within or immediately adjacent to the project site. STATE OF WASHINGTON DEPARTMENT OF FISH AND WILDLIFE The State of Washington Department of Fish and Wildlife (WDFW) mapping was reviewed as a part of this assessment (Figure 4). This mapping resource did not identify any streams within or immediately adjacent to the project site. STATE OF WASHINGTON DEPARTMENT OF NATURAL RESOURCES The State of Washington Department of Natural Resources (WDNR) mapping was reviewed as a part of this assessment (Figure 5). This mapping resource identified did not identify any streams within or immediately adjacent to the project site. CITY OF FEDERAL WAY MAPPING The City of Federal Way Inventory Mapping was reviewed as a part of this assessment (Figure 6). This mapping resource identified a stream to the west of the project site and a wetland offsite to the northwest of the northwestern corner of the project site. SOILS MAPPING The soil mapping inventory completed by the Soils Conservation Service (now the Natural Resource Conservation Service) was reviewed as a part of this assessment (Figure 7). This mapping resource identified the soil throughout the project site as Alderwood gravelly sandy loam. This soil series is defined as formed in glacial till, as moderately well drained, and to potentially exhibit inclusion of "hydric" soil. WASHINGTON STATE NATURAL HERITAGE PROGRAM The Washington State Natural Heritage Program was reviewed as a part of this assessment. This resource did not identify any high quality, undisturbed wetland or a 2 17177 wetland that supports state Threatened, Endangered, or Sensitive plant species within the Section/Township/Range of the project site. ONSITE ANALYSIS CRITERIA FOR CRITICAL AREAS IDENTIFICATION The City of Federal Way has identified that the following areas of the environment are designated as "critical areas" pursuant to RCW 36.70A.030(5) (14.30.010): Critical aquifer recharge areas and wellhead protection areas; • Fish and wildlife habitat conservation areas; • Frequently flooded areas; Geologically hazardous areas; • Regulated wetlands; and Streams. However, for the purpose of this document only fish and wildlife habitat conservation areas, wetlands, and streams were specifically assessed. Wetlands: Wetlands are transitional areas between aquatic and upland habitats. In general terms, wetlands are lands where the extent and duration of saturation with water is the primary factor determining the nature of soil development and the types of plant and animal communities living in the soil and on its surface (Cowardin, et al., 1979). Wetlands are generally defined within land use regulations as "areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" (United States Army Corps of Engineers, 1987). Wetlands exhibit three essential characteristics, all of which must be present for an area to meet the established criteria (United States Army Corps of Engineers, 1987 and United States Army Corps of Engineers, 2010). These essential characteristics are: 1. Hydrophytic Vegetation: The assemblage of macrophytes that occurs in areas where inundation or soil saturation is either permanent or of sufficient frequency and duration to influence plan occurrence. Hydrophytic vegetation is present when the plant community is dominated by species that require or can tolerate prolonged inundation or soil saturation during the growing season. 2. Hydric Soil: A soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper parts. Most hydric soils exhibit characteristic morphologies that result from repented periods of saturation or inundation. These processes result 3 17177 in distinctive characteristics that persist in the soil during both wet and dry periods. 3. Wetland Hydrology: Permanent or periodic inundation, or surface soil saturation, at least seasonally. Wetland hydrology indicators are used in combination with indicators of hydric soil and hydrophytic vegetation to define the area. Wetland hydrology indications provide evidence that the site has a continuing wetland hydrology regime. Where hydrology has not been altered vegetation and soils provide strong evidence that wetland hydrology is present. Streams: A stream (aquatic area) is generally defined as a location where surface waters produce a defined channel or bed. A defined channel or bed is typically an area which demonstrates clear evidence of the passage of water and includes, but not limited to, bedrock channels, gravel beds, sand and silt beds, and defined channel swales. A stream need not contain water year-round. A stream typically does not include irrigation ditches, canals, storm or surface water run-off devices, or other artificial watercourses unless the constructed watercourse conveys a stream which naturally occurred prior to the construction of such watercourse. Fish and Wildlife Habitat Conservations Areas: "Fish and wildlife habitat conservation areas" are defined by the City of Federal Way as the management of land for maintaining species in suitable habitats within their natural geographic distribution so that isolated subpopulations are not created. Habitat conservation areas include but are not limited to such areas as. a) Streams; b) Regulated Lakes; c) Areas with state or federally designated endangered, threatened, and sensitive species have a primary association; d) Federally designated endangered and threatened species are those fish and wildlife species identified by the U.S. Fish and Wildlife Service and the NOAA Fisheries that are in danger of extinction or threatened to become endangered. The U.S. Fish and Wildlife Service and the National Marine Fisheries Service should be consulted for current listing status; e) State -designated endangered, threatened, and sensitive species are those fish and wildlife species native to the state of Washington identified by the Washington Department of Fish and Wildlife that are in danger of extinction, threatened to become endangered, vulnerable, or declining; f) State priority habitats and areas associated with state priority species; g) Habitats and species of local importance. STUDY METHODS Habitat Technologies completed onsite assessments from August through October 2017. In addition, Habitat Technologies has completed a number of similar assessments for parcels located within the general area of the project site. The 4 17177 objective of this evaluation was to define and delineate potential critical areas (wetlands, drainage corridors, and critical habitats) that may be present within or immediately adjacent to the project area. Onsite activities were completed in accordance with criteria and procedures established in the Corps of Engineers Wetland Delineation Manual (United States Army Corps of Engineers, 1987) with the Regional Supplement to the Corps of Engineers Wetland Delineation Manual. Western Mountains, Valleys, and Coast Region (United States Army Corps of Engineers, 2010); the Washington State Wetland Rating System for Western Washington: 2014 Update Publication #14- 06-029 (Hruby, 2014), the State of Washington Department of Natural Resources (WDNR) Forest Practice Rules (WAC 222-16-030), and the City of Federal Way Title 19.145 — Environmentally Critical Areas. FIELD OBSERVATION The project site was accessed via existing paved public roadway along the western and southern boundaries of the project site, and by a utility corridor along the northern boundary of the project site. The entire project site had been modified by prior land use actions to include prior forest harvest, prior clearing and grading, the development of adjacent single-family homesites, and the development of public roadways and utilities. The project site was located within an urban residential area dominated by existing single-family homesites. Plant Communities The plant community throughout the project site had been modified by prior land use actions, onsite and offsite. The project site was dominated by a deciduous forest plant community that had become established following prior forest harvest and clearing actions. The dominate tree species were big leaf maple (Acer macrophyllum), bitter cherry (Prunus emargenata), one -seed hawthorne (Crataegus monogyna), and red alder (Alnus rubra). A few small areas of the project site were dominated by small stands of second growth Douglas fir (Pseudotsuga menziesii). The understory was well established and included sapling trees, Himalayan blackberry (Rubus procera), evergreen blackberry (Rubus laciniatus), Pacific blackberry (Rubus ursinus), hazelnut (Corylus cornuta), Indian plum (Oemleria cerasiformis), holly (Ilex spp.), vine maple (Acer circinatum), sword fern (Polystichum munitum), bracken fern (Pteridium aquilium), geranium (Geranium spp.), common horsetail (Equisetum arvense), and ivy (Hedera spp.). This plant community was identified as non-hydrophytic in character (i.e. typical of non -wetlands). As viewed from the project boundary, the vacant area located direction to the north of the project site also exhibited a similar typically upland plant community to that noted onsite. A drainage corridor was identified offsite to the northwest of the northwestern corner of the project site. The plant community along this plant community appeared dominated by red alder, young black cottonwood, willows (Salix spp.), blackberries, and Douglas spiraea (Spiraea douglasii). 5 17177 e Hydrology The entire project site appeared to drain moderately well to well and did not exhibit seasonal hydrology patterns or hillside seep patterns typical of wetlands or seasonal surface water drainages. A buried culvert was noted to day -light near the north -central boundary of the project site, generally along the northern edge of a utility corridor along the northern boundary of the project site. This culvert appeared to convey and discharge seasonal stormwater from the developed areas to the east of the project site. Surface water from this culvert was conveyed to the west within an excavated ditch along the northern edge of the utility corridor. At the northwestern corner of the project site this stormwater was directed offsite to the north into a vacant parcel. This stormwater did not exhibit a channel or defined drainage pattern to a regional stormwater drainage offsite to the northwest. As viewed from the project site boundary the surface water from this stormwater culvert and associated ditch appeared in infiltrate quickly just to the north of the northwestern corner of the project site. Soils As identified at a representative sample plot throughout the project site the onsite soil appeared to drain moderately well to well and did not exhibit field indicators of "hydric" soil characteristics. The surface soil to a depth of approximately four (4) to eight (8) inches was very dark grayish brown (10YR 3/2) to dark brown (10YR 3/3) in color and exhibited a texture of gravelly loam to sandy loam. The subsoil to a depth of approximately 22 inches was dark yellowish brown (10YR 3/4 to 10YR 4/4) and exhibited a texture of gravelly loam to sandy loam. The soil did not exhibit prominent field indicators of hydric soils. • Wildlife Species and Habitats The project site and surrounding areas had been modified and manipulated by prior and ongoing land use activities. The areas to the west, south, and east of the project site had been developed into single family homesites with managed yards. The area onsite and immediately offsite to the north was dominated by a typically upland deciduous forest plant community. Wildlife species observed or that would be expected onsite or within the immediate vicinity of the project site based on existing habitats would include American crow (Corvus brachynchos), common raven (Corvus coraw), American robin (Turdus migratorius), Steller's jay (Cyanocitta stellen), tree swallow (Tachycineta bicolor), violet green shallow (Tachycineta thallassina), song sparrow (Melospiza melodia), dark eyed junco (Junco hyemalis), starling (Sturnus vulgaris), bushtit (Psaltriparus minimus), house finch (Passer domesticus), black -capped chickadee (Parus atricapillus), brown creeper (Certhia americana), red-tailed hawk (Buteo jamaicensis), Northern flicker 6 17177 (Colaptes auratus), hairy woodpecker (Picoides villosus), northern flicker (Colaptes auratus), purple finch (Carpodacus purpureus), rufous sided towhee (Pipilo erythrophthalmus), evening grosbeak (Coccothraustes vespertina), coyote (Canis latrans), opossum (Didelphis virginianus), eastern gray squirrel (Sciurus griseus), striped skunk (Mephitis mephitis), raccoon (Procyon lotor), eastern cottontail (Sylvilagus floridanus), deer mouse (Peromyscus maniculatus), Norway rat (Rattus norvegicus), shrew (Sorex spp.), bats (Myotis spp.), and common garter snakes (Thamnophis sirtalis). The area associated with the regional drainage corridor offsite to the northwest may provide limited habitats for Pacific treefrogs (Hyla regilla). No portion of the project site, and the regional drainage corridor offsite to the northwest of the project site was identified to provide direct habitats for fish species. Movement Corridors: The project site had been modified by prior land uses and was generally bound by existing urban developments. The movement of wildlife appeared restricted by the development of adjacent homesites and residential developments, and both public and private roadways. However, a number of small and medium sized wildlife trails were identified within the project site. The project site was within the seasonal migratory pathways for a variety of passerine birds. State Priority Species: Priority species require protective measures for their survival due to their population status, sensitivity to habitat alteration, and/or recreational, commercial, or tribal importance. Game Species: "Game species" are regulated by the State of Washington through recreational hunting bag limits, harvest seasons, and harvest area restrictions. No "game species" were identified within or adjacent to the project site. State Candidate: State Candidate species are presently under review by the State of Washington Department of Fish and Wildlife (WDFW) for possible listing as endangered, threatened, or sensitive. No State Candidate species were identified within or adjacent to the project site. State Monitored: State Monitored species are native to Washington but require habitat that has limited availability, are indicators of environmental quality, require further assessment, have unresolved taxonomy, may be competing with other species of concern, or have significant popular appeal. No critical habitat was identified onsite for State Monitored species and no State Monitored species were identified or have been documented within or adjacent to the project site. State Sensitive: State Sensitive species are native to Washington, are vulnerable to decline, and are likely to become endangered or threatened throughout a significant portion of its range without cooperative management or removal of threats. No critical habitat was identified onsite for State Sensitive 7 17177 species and no State Sensitive species were identified or have been documented within or adjacent to the project site. State Threatened: State Threatened species are species native to the state of Washington and are likely to become an endangered species within the foreseeable future throughout a significant portion of its range within the state without cooperative management or removal of threats. No critical habitat was identified onsite for State Threatened species and no State Threatened species were identified or have been documented within or adjacent to the project site. State Endangered: State endangered species are species native to the state of Washington and are seriously threatened with extinction throughout all or a significant portion of its range within the state. No critical habitat was identified onsite for State Endangered species and no State Endangered species were identified or have been documented within or adjacent to the project site. Federally Listed Species. The project site has not been documented to provide critical habitats for federally listed endangered, threatened, or sensitive species. CRITICAL AREAS DETERMINATION Onsite critical areas assessment activities were completed in accordance with the methods and procedures defined in the Corps of Engineers Wetland Delineation Manual (United States Army Corps of Engineers, 1987) with the Regional Supplement to the Corps of Engineers Wetland Delineation Manual. Western Mountains, Valleys, and Coast Region (United States Army Corps of Engineers, 2010); the Washington State Wetland Rating System for Western Washington: 2014 Update Publication #14-06-029 (Hruby, 2014), the State of Washington Department of Natural Resources (WDNR) Forest Practice Rules (WAC 222-16-030), and the City of Federal Way Title 19.145 — Environmentally Critical Areas. This assessment identified that no portion of the project site exhibited all three of the required criteria for designation as a "wetland" and that no portion of the project site exhibited field indicators typically associated with a "stream." In addition, no portion of the project site was identified to provide critical habitats for federally or state listed endangered, threatened, or sensitive species; to provide state listed priority habitats; or to provide habitats for species of local importance. This assessment did identify a regional drainage corridor offsite to the northwest of the northwestern corner of the project site. As defined in the City of Federal Way Inventory Mapping (Figure 6), this drainage was noted as a "stream" immediately west of the project site. However, this "stream" is presently confined within a buried City of Federal Way stormwater system associated with 18th Avenue SW. offsite to the northwest of the project site, this drainage corridor appeared to have been ditched/channelized as a part of the development of the Twin Lake Park and Ride to direct seasonal stormwater runoff to the north. This offsite drainage corridor appeared best defined as an artificial 8 17177 watercourse intentionally created to address regional stormwater concerns and management. As identified during the onsite assessment a recent, similar assessment of the parcel located directly to the north of the project site had also been completed. The findings of this recent assessment have not yet been made available. However, as viewed from the northern boundary of the project site no area immediately adjacent to the project site appeared to meet all three criteria for designation as a "wetlands." SELECTED DEVELOPMENT ACTION The Selected Development Action for Parcel 2421039018 focuses on the development of a single-family homesite community consistent with the City of Federal Way Comprehensive Plan, local zoning, and the character of the local area. As presently outlined the development of these new homesites would not encroach or adversely impact wetlands, streams, or critical habitat areas. STANDARD OF CARE This critical areas assessment has been completed by Habitat Technologies for use by Maria and Antonio Pena, and ESM Consulting Engineers, Inc. Prior to extensive site planning the findings documented in this document should be reviewed and verified by City of Federal Way. Habitat Technologies has provided professional services that are in accordance with the degree of care and skill generally accepted in the nature of the work accomplished. No other warranties are expressed or implied. Habitat Technologies is not responsible for design costs incurred before this document is approved by the appropriate resource and permitting agencies.

EROSION/SEDIMENTATION CONTROL NOTES (CITY STD NOTES) 1. APPROVAL OF THIS EROSION/SEDIMENTATION CONTROL (ESC) PLAN DOES NOT CONSTITUTE AN APPROVAL OF PERMANENT ROAD OR DRAINAGE DESIGN (I.E. SIZE AND LOCATION OF ROADS, PIPES, RESTRICTORS, CHANNELS, RETENTION FACILITIES, UTILITIES, ETC.). 2. THE IMPLEMENTATION OF THESE ESC PLANS AND THE CONSTRUCTION, MAINTENANCE, REPLACEMENT, AND UPGRADING OF THESE ESC FACILITIES IS THE RESPONSIBILITY OF THE APPLICANT/CONTRACTOR UNTIL ALL CONSTRUCTION IS APPROVED. 3. THE BOUNDARIES OF THE CLEARING LIMITS SHOWN ON THIS PLAN SHALL BE CLEARLY FLAGGED IN THE FIELD PRIOR TO CONSTRUCTION. DURING THE CONSTRUCTION PERIOD, NO DISTURBANCE BEYOND THE FLAGGED CLEARING LIMITS SHALL BE PERMITTED. ;THE FLAGGING SHALL BE MAINTAINED BY THE APPLICANT/CONTRACTOR FOR THE DURATION OF CONSTRUCTION. 4. THE ESC FACILITIES SHOWN ON THIS PLAN MUST BE CONSTRUCTED IN CONJUNCTION WITH ALL CLEARING AND GRADING ACTIVITIES, AND IN SUCH A MANNER AS TO INSURE THAT SEDIMENT LADEN WATER DOES NOT ENTER THE DRAINAGE SYSTEM OR VIOLATE APPLICABLE WATER STANDARDS. 5. THE ESC FACILITIES SHOWN ON THIS PLAN ARE THE MINIMUM REQUIREMENTS FOR ANTICIPATED SITE CONDITIONS. DURING THE CONSTRUCTION PERIOD, THESE ESC FACILITIES SHALL BE UPGRADED (I.E. ADDITIONAL SUMPS, RELOCATION OF DITCHES AND SILT FENCES, ETC.) AS NEEDED FOR UNEXPECTED STORM EVENTS. 6. THE ESC FACILITIES SHALL BE INSPECTED DAILY BY THE APPLICANT/CONTRACTOR AND MAINTAINED AS NECESSARY TO ENSURE THEIR CONTINUED FUNCTIONING. 7. ANY AREA STRIPPED OF VEGETATION, INCLUDING ROADWAY EMBANKMENTS, WHERE NO FURTHER WORK IS ANTICIPATED OR A PERIOD OF 15 DAYS, SHALL BE IMMEDIATELY STABILIZED WITH THE APPROVED ESC METHODS (I.E. SEEDING, MULCHING, NETTING, EROSION BLANKETS, ETC.) 8. ANY AREA NEEDING ESC MEASURES, NOT REQUIRING IMMEDIATE ATTENTION, SHALL BE ADDRESSED WITHIN 15 DAYS. 9. THE ESC FACILITIES ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED A MINIMUM OF ONCE A MONTH OR WITHIN THE 48 HOURS FOLLOWING A STORM EVENT. 10. AT NO TIME SHALL MORE THAN ONE FOOT OF SEDIMENT BE ALLOWED TO ACCUMULATE WITHIN A CATCH BASIN. ALL CATCH BASINS AND CONVEYANCE LINES SHALL BE CLEANED PRIOR TO PAVING. THE CLEANING OPERATION SHALL NOT FLUSH SEDIMENT -LADEN WATER INTO THE DOWNSTREAM SYSTEM. 11. STABILIZED CONSTRUCTION ENTRANCES AND WASH PADS SHALL BE INSTALLED AT THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE DURATION OF THE PROJECT. ADDITIONAL MEASURES MAY BE REQUIRED TO INSURE THAT ALL PAVED AREAS ARE KEPT CLEAN FOR THE DURATION OF THE PROJECT. 12. WET SEASON REQUIREMENTS AS DESCRIBED IN APPENDIX D, SECTION D.5.2 OF THE KCSWDM ARE IN EFFECT BEGINNING OCTOBER 1 THROUGH APRIL 30. 13. ANY PERMANENT RETENTION/DETENTION FACILITY USED AS A TEMPORARY SETTLING BASIN SHALL BE MODIFIED WITH THE NECESSARY EROSION CONTROL MEASURES AND SHALL PROVIDE ADEQUATE STORAGE CAPACITY. IF THE PERMANENT FACILITY IS TO FUNCTION ULTIMATELY AS AN INFILTRATION OR DISPERSION SYSTEM, THE FACILITY SHALL NOT BE USED AS A TEMPORARY SETTLING BASIN. NO UNDERGROUND DETENTION TANKS OR VAULTS SHALL BE USED AS A TEMPORARY SETTLING BASIN. 14. WHERE SEEDING FOR TEMPORARY EROSION CONTROL IS REQUIRED, FAST GERMINATING GRASSES SHALL BE APPLIED AT AN APPROPRIATE RATE (I.E. ANNUAL OR PERENNIAL RYE APPLIED AT APPROXIMATELY 80 POUNDS PER ACRE). 15. WHERE STRAW MULCH FOR TEMPORARY EROSION CONTROL IS REQUIRED, IT SHALL BE APPLIED AT A MINIMUM THICKNESS OF TWO INCHES. 16.
