Snohomish County PUD comment IV. FINDINGS OF FACT, ANALYSIS AND CONCLUSIONS A. Setting The three -parcel site is located within a larger built -out residential neighborhood on the eastern edge of the downtown Edmonds "Bowl" (Attachment 4 and Sheet PP-01 of Attachment 5). The subject properties and those immediately surrounding it are zoned RS-8 (single-family residential; 8,000 square foot minimum lot size). An area of RS-10 (single-family residential; 10,000 square foot minimum lot size) is located to the southwest across 98t" Avenue West. B. Public Notice and Comments The subject application was submitted on May 3, 2018 and determined to be complete on May 30, 2018. In accordance with ECDC 20.03, a "Notice of Application" was posted at the subject site, Public Safety Complex, Development c co Services Department, and Library on June 11, 2018 (Attachment 9). The notice was also published in the Herald Newspaper and mailed to property owners within 300 Z feet of the site using a mailing list provided by the applicant. Notice was also a provided to the Town of Woodway and Snohomish County since those jurisdictions r are within one mile of the project site. The Notice of Public Hearing and SEPA Determination was published in the Everett w Herald, posted at the subject site, Public Safety Complex, Development Services Department, and Library on November 13, 2018 (Attachment 17). The notice was E also mailed to property owners within 300 feet of the site using the mailing list �a r w Q Westhaven Preliminary Plat File No. PLN20180034 Page 2 of 14 Packet Pg. 4 2.1.a provided by the applicant. Notice was also provided to the Town of Woodway and Snohomish County since those jurisdictions are within one mile of the project site. Two written comments on the proposed subdivision have been received as of the writing of this report. Janelle and Chris Cass are concerned about the change of the current dead-end at 215th Place SW into a cul-de-sac (Attachment 10). They feel the change will lead to a decrease in their property value because of the increase in traffic generated from six of the proposed ten new building lots taking access from 215th Place. Staff Response: As shown on the aerial photos in Attachment 4, the proposed plat is an infill project within a built -out single family residential neighborhood. While it could be possible to arrange the development differently, the proposed development meets all applicable code requirements. With an additional six lots accessing 215th Place, a cul-de-sac is required within the proposed project area. This will improve emergency access on 215th Place but it will not turn it into a through street. While six additional houses would use 215th Place, values of the existing houses along the street should be little impacted by the extension of the road into a cul-de-sac since it will still be a dead end. Pam Rabe submitted a comment regarding the potential loss of trees near the south edge of her lot that is adjacent to the proposed project (Attachment 11). Staff Response: Ms. Rabe's lot at 9708 214th Place SW is adjacent to proposed Lot 6 (see Sheet PP-01 of Attachment 5). Sheet TP-01 of Attachments 6 shows the extent of proposed clearing and grading that will be associated with the plat (bubbled highlight). Much of the area on proposed Lot 6 adjacent to Ms. Rabe's lot is not proposed to be cleared as part of the installation of the civil subdivision improvements such as utilities, stormwater and the cul-de-sac and frontage improvements (those can be seen on Sheet UT-01 of Attachment 6). Eventually, additional grading and site work will likely take place on Lot 6 as part of the construction of the single family residence so there is a possibility that additional trees would be removed at that time. The location of a possible house on Lot 6 is generally reflected on Sheet CV-01 of Attachment 6 (Lot 6 would be considered to be a flag lot and so would have 7.5-foot setbacks from all property lines). As seen on Sheet TP-01, there are two trees (a 13" deciduous and a 30" fir) either on or very near the shared property line between proposed Lot 6 and the Rabe parcel to the north. A condition is proposed to ensure any property line trees are appropriately managed at the time of single family development. Westhaven Preliminary Plat File No. PLN20180034 Page 3 of 14 Packet Pg. 5 2.1.a C. Environmental Assessment Critical Areas: The subject properties were reviewed and inspected for critical areas as defined by ECDC 23.40 under CRA20180083 and it was determined the site does not contain any critical areas. 2. Shoreline: The subject property is not located within shoreline jurisdiction. 3. SEPA: Review under the State Environmental Policy Act (SEPA) is required for formal subdivisions. The applicants completed the SEPA checklist included as Attachment 12. A Determination of Nonsignificance (DNS) was issued on November 13, 2018 for the formal subdivision (-Attachment 13). The DNS was posted, mailed to adjacent property owners and published in accordance with ECDC 20.03.004 (Attachment 17). Snohomish County PUD commented that the District has sufficient system capacity to serve the project. They noted the developer is responsible for the costs of new equipment or relocating existing equipment and will need to work with the utility to obtain appropriate permits (Attachment 18). No appeals of the SEPA determination were received. D. ECDC 20.75.085 — Subdivision Review Criteria. In addition to staff from the Planning Division, staff from South Snohomish County Fire and Rescue, and the City's Public Works, Building and Engineering Divisions reviewed the proposal. The following criteria are used to evaluate preliminary subdivisions: 1. Environmental. a. Where environmental resources existing, such as trees, streams, ravines or wildlife habitats, the proposal shall be designed to minimize significant adverse impacts to resources. Permanent restrictions may be imposed on the proposal to avoid impact. There are no critical areas on or adjacent to the subject site but there are a number of trees present spread throughout the three parent parcels. Sheets TP-01 and UT-01 of Attachment 6 show that many existing trees would be removed during the construction of the proposed plat improvements and utilities. Sheet CV-01 shows that many of the remaining trees would likely be removed during the single family construction process based on the possible location of building footprints. The trees in the two 'save' areas shown on Sheet TP-01 must be protected r during plat development in accordance with the performance standards in ECDC 18.45.050.H. A proposed condition to this effect has been added to x staffs recommendation. As mentioned before, a condition is also proposed w to manage property line trees. E Westhaven Preliminary Plat File No. PLN20180034 Page 4 of 14 �a r w Q Packet Pg. 6 2.1.a b. The proposal shall be designed to minimize grading by using shared driveways and by relating street, house site and lot placement to the existing topography. The proposal minimizes grading for construction of the civil improvements by proposing a balance of cuts and fills across the largely level site (Sheet TP-01 of Attachment 6). c. Where conditions exist which could be hazardous to the future residents of the land to be divided, or to nearby residents or property, such as flood plains, steep slopes or unstable soil or geologic conditions, a subdivision of the hazardous land shall be denied unless the condition can be permanently corrected, consistent with paragraphs A(1) and (2) of this section. No known hazardous conditions, such as flood plains, steep slopes, or unstable soil or geologic conditions exist at this site. d. The proposal shall be designed to minimize off -site impacts on drainage, views and so forth. Staff from the Public Works Department and Engineering Division reviewed the preliminary plans and found that the information provided indicates general engineering feasibility for stormwater, utilities, and related civil improvements (Attachment 16). The specific improvements, including final utility system design and location, as well as Title 18 Edmonds Community Development Code compliance, will be reviewed during the civil construction phase of this project. Inspections occur throughout the construction process to verify compliance with the approved civil plans. Views in the area are territorial. The maximum height for a new house in the RS-8 zone is 25 feet from average original grade, which serves to minimize the negative impact to existing views in the vicinity. Aside from the height limits, the Edmonds Community Development Code does not contain specific regulations regarding private view protection within single-family zones. 2. Lot and Street Layout. a. Lots shall be designed to contain a usable building area. If the building area would be difficult to develop, the lot shall be redesigned or eliminated, unless special conditions can be imposed on the approval which will ensure that the lot is developed properly. All ten lots in the proposed subdivision are fairly level and have been r designed to accommodate single-family residences. The preliminary development plans show the potential location of a new residence on each w of the proposed lots (Attachment 6). Specific locations for each of the houses will be reviewed through individual building permits for the structures and will be verified through inspections. �a r w Q Westhaven Preliminary Plat File No. PLN20180034 Page 5 of 14 Packet Pg. 7 2.1.a b. Lots shall not front on highways, arterials or collector streets unless there is no other feasible access. Special access provisions, such as shared driveways, turnarounds or frontage streets may be required to minimize traffic hazards. Six of the proposed lots will use the improved cul-de-sac at 215th Place while the other four lots will access 98th Avenue West. None of the lots access highways, arterials or collector streets. Both South County Fire and the Engineering Division noted the proposed layout meets access requirements (Attachment 16). c. Each lot shall meet the applicable dimensional requirements of the zoning ordinance. The subject property is located in the RS-8 Single -Family Residential zone and is subject to the requirements of ECDC 16.20. Compliance with each of the standards is verified during review of building permits for each single family residence. Pursuant to ECDC 16.20.030, development standards of the RS-8 zone are: Minimum Minimum Minimum Minimum Maximum Maximum Lot Area Minimum Zone Lot Width Street � Side Rear Height Coverage (Sq.Ft.) Setback Setback Setback LRS-8 8,000 70' 25 7.5 15' 25' 35% Minimum Lot Area: Each of the ten proposed lots must contain at least 8,000 square feet net (lot area normally excludes the area of street rights -of - way and access easements). As seen on Sheet PP-01 of Attachment 5, the street right-of-way area within the cul-de-sac is removed from the calculation (37' radius). The associated 8' public pedestrian and utility easement adjacent to the right-of-way is not excluded. The proposed lots meet the minimum area requirement for the zone. Required Lot Area Lot 1 8,000_ Lot 2 8,000 Lot 3 8,000 Lot 4 8,000 Lot 5 8,000 Lot 6 8,000 Lot 7 8,000 Proposed Gross Area (sq. ft.) Proposed Net Area (sq. ft.) 8,030 8,030 8,030 8,030 8,030 8,030 8,029 8,029 8,023 8,023 8,036 8,036 8,996 8,021 Westhaven Preliminary Plat File No. PLN20180034 Page 6 of 14 Packet Pg. 8 2.1.a Loth 8,000 8,987 8,024 Lot 9 8,000 8,033 8,033 Lot 10 8,000 8,032 8,032 Minimum Lot Width: Pursuant to ECDC 21.55.050, lot width is the minimum diameter of a lot width circle that must fit within a lot (70 feet in this zone). A 70-foot diameter lot width circle fits into each of the ten proposed lots; therefore the proposal is consistent with the lot width requirement. Corner Lots: None of the proposed lots are corner lots. Flag Lots: Lots 6 & 9 would be considered flag lots since each has frontage of less than one-half of the minimum lot width at the cul-de-sac. Setbacks: Based on the development standards for the RS-8 zone, setbacks for the proposed lots should be: Lots 1- 4: Street setback (25 feet): Side setback (7.5 feet): Rear setback (15 feet): Lots 7 & 8: Street setbacks (25 feet): Side setbacks (7.5 feet): Rear setback (15 feet) From west property lines From north/south property lines From east property line From east property lines From north/south property lines (and that portion adjacent to the access easement) From west property lines Lots 6 & 9: Side setbacks all around (7.5 feet) Lots 5 & 10: Street Setbacks (25 feet): From cul-de-sac property line Side Setback (7.5 feet): From east/west property lines Rear setback (15 feet): From opposite cul-de-sac Lot Coverage of Existing Buildings on Proposed Lots: All existing structures are to be removed so there will be no lot coverage remaining after the subdivision. The Building Division noted that building permits will be required for the demolition of the existing structures (Attachment 14). d. Pedestrian walks or bicycle paths shall be provided to serve schools, parks, public facilities, shorelines and streams where street access is not adequate. Citywide efforts to provide safe transportation include enforcement of traffic regulations, provision of crosswalk and sidewalks for pedestrians, and provision of well -designed streets for safe driving. Safety also involves ongoing coordination with emergency service providers to ensure access for their emergency equipment. Recommendations to address safety issues are Westhaven Preliminary Plat File No. PLN20180034 Page 7 of 14 a Packet Pg. 9 2.1.a based on assessment of historical collision data, focused sub -area or corridor safety studies, or on citizen feedback. The City of Edmonds applies a Walkway Prioritization Process provided in the Transportation Element of the Comprehensive Plan in assessing where sidewalks should be required or upgraded. Criteria have been developed to evaluate and prioritize walkway improvement projects. These criteria (which include distance from schools) are used to prioritize improvements to walkway sections that are identified based on input from public meetings, Walkway Committee meetings, and deficiencies determined from a review of the existing city walkway inventory. The criteria are weighted according to their importance and a system of points is used to evaluate each proposed project against each criterion. The result is a weighted average score that helps to compare and prioritize proposed projects. The City's policy is to consider these criteria in conjunction with City code and the Sidewalk Comprehensive Plan Map in determining sidewalk requirements for subdivisions. Per the City Engineering Division requirements (Attachment 16), no sidewalks are required at 98th Avenue West since there are existing sidewalks on the other side of the street south of the project site but sidewalks are required to be constructed around the cul-de-sac at 215th Place as part of the subdivision process. 3. Dedications a. The city council may require dedication of land in the proposed subdivision for public use. b. Only the city council may approve a dedication of park land to satisfy the requirements of ECDC 20.75.090. The council may request a review and written recommendation from the planning advisory board. c. Any approval of a subdivision shall be conditioned on appropriate dedication of land for streets, including those on the official street map and the preliminary plat. Per the Engineering Division requirements in Attachment 16, the cul-de-sac area at 215th Place must be dedicated to the City. Regarding park land dedication, according to ECDC 20.75.090, before or concurrent with the approval of the final plat of any subdivision, the subdivider shall dedicate land, pay a fee in -lieu of dedication, or do a combination of both, for park and recreational purposes. With the adoption of Ordinance 3934 in 2013, park impacts are now addressed through the assessment of park impact fees in accordance with Edmonds City Code (ECC) Chapter 3.36. No park dedication or fees are required with the subdivision. Westhaven Preliminary Plat File No. PLN20180034 Page 8 of 14 Packet Pg. 10 2.1.a Park impact fees will be assessed with issuance of the future building permits on the new lots consistent with ECC 3.36. The Building Division noted that park impact fees will be waived for up to three new homes provided the applications are submitted within one year of issuance of the associated demolition permits (Attachment 14). 4. Improvements. a. Improvements which may be required, but are not limited to, streets, curbs, pedestrian walks and bicycle paths, sidewalks, street landscaping, water lines, sewage systems, drainage systems and underground utilities. b. The person or body approving a subdivision shall determine the improvements necessary to meet the purposes and requirements of this chapter, and the requirements of. i. ECDC Title 18, Public Works Requirements, ii. Chapter 19.75, Fire Code, as to fire hydrants, water supply and access. This determination shall be based on the recommendations of the community development director, the public works director, and the fire chief. As noted before, the preliminary plat was reviewed by South County Fire as well as the Public Works Department (including utilities, stormwater, sewer and water, operations, and the Engineering Division). Each group found the preliminary proposal to be feasible but will review the required civil improvement plans in the future to ensure compliance. The Engineering Division summarized preliminary approval in the compliance memo and engineering requirements in Attachment 16. c. The use of septic systems maybe approved if all of the following conditions are met: i. It is more than 200 feet, multiplied by the number of lots in the proposed subdivision, from the nearest public sewer main to the nearest boundary of the land to be divided. ii. The land to be divided is zoned RS-20. iii. The public works director and city health officer determine that soil, drainage and slope conditions are satisfactory for septic use and that all requirements of WAC 248-95-090 are met. r There are no septic systems included as part of the proposed project. 5. Flood Plain Management. All subdivisions shall comply with the criteria set forth w in the Edmonds community Development code for flood plain management. c The subject property is not located within a Flood Plain Management area. E �a r Westhaven Preliminary Plat File No. PLN20180034 Page 9 of 14 w Q Packet Pg. 11 2.1.a E. ECDC 20.75.080 General Findings A proposed subdivision may only be approved if all the general findings listed in ECDC 20.75.080 can be made for the proposal as approved or as conditionally approved. Staff's findings in regard to ECDC 20.75.080 are detailed below. Subdivision Ordinance. The proposal is consistent the purposes of this chapter (as listed in ECDC 20.75.020) and meets all requirements of this chapter. The proposed ten lot subdivision is consistent with ECDC 20.75.020 and all the requirements of the ECDC 20.75. The proposed subdivision will not negatively impact public health, safety or general welfare, will not negatively impact congestion on streets and highways, will have adequate access to water, utilities, sewerage, storm drainage and will provide proper ingress and egress as well as be uniformly monumented. 2. Comprehensive Plan. The proposal is consistent with the provisions of the Edmonds Comprehensive Plan, or other adopted city policy, and is in the public interest. The subject property is located within the Single Family Urban 1 comprehensive plan designation. The Comprehensive Plan has the following stated goals and policies for Residential Development that apply to this project. Residential Development B. Goal. High quality residential development which is appropriate to the diverse lifestyle of Edmonds residents should be maintained and promoted. The options available to the City to influence the quality of housing for all citizens should be approached realistically in balancing economic and aesthetic consideration, in accordance with the following policies: B.1. Encourage those building custom homes to design and construct homes with architectural lines which enable them to harmonize with the surroundings, adding to the community identity and desirability. B.3. Minimize encroachment on view of existing homes by new construction or additions to existing structures. B.S. Protect residential areas from incompatible land uses through the careful control of other types of development and expansion based upon the following principles: B.S.a. Residential privacy is a fundamental protection to be upheld by local government. B.S.b. Traffic not directly accessing residences in a neighborhood must be discouraged. Westhaven Preliminary Plat File No. PLN20180034 Page 10 of 14 w Q Packet Pg. 12 2.1.a 8.5.c. Stable property values must not be threatened by view, traffic or land use encroachments. 8.5.d. Private property must be protected from adverse environmental impacts of development including noise, drainage, traffic, slides, etc. B.6. Require that new residential development be compatible with the natural constraints of slopes, soils, geology, vegetation and drainage. Compliance with the Residential Development goals and policies: The proposal will allow for ten new homes to be built on the site where there are currently three. Traffic impact fees consistent with Chapter 18.82 ECDC are collected with building permits for each individual lot to mitigate traffic impacts. The overall proposal should not cause any adverse impacts and appears to be consistent with the residential development goals and policies of the Comprehensive Plan. 3. Zoning Ordinance. The proposal meets all requirements of the zoning ordinance, or a modification has been approved as provided for in this chapter. The subject property is located within the RS-8 zone. All proposed lots contain at least 8,000 square feet net and are at least 70 feet in width and thus compliant with the dimensional requirements of the RS-8 zone. No modifications were requested. 4. Flood Plain Management. The proposal meets all requirements of the Edmonds Community Development code relating to flood plain management. The proposed project is not located within a designated flood plain management area. V.

PROJECT OVERVIEW: This report provides engineering information for the proposed construction of a 10-lot single family residence plat on a 1.99 ac parcel; the project is located on the west side of 981h Ave SW (north of 216th St SW) in the City of Edmonds. The applicant, Select Homes proposes to remove the existing residences (three) and all existing hard surface to construct the 10-lot plat on the project site. This report provides the evaluation for the new ten single family residential development. Summary of Minimum Requirements for Category 1 Project: Minimum Requirement #1 —Preparation of Stormwater Site Plan. The proposed site development consists of disturbing about 2.0 acres of land and creating/replacing about 49,400 sf of hard surface area. Thus, the project is classified as a Category 2 project per the City's classification system. Per ECDC 18.30, Category 2 projects must comply with Minimum Requirements No. 1 through No. 9. The civil site development plans and this report have been prepared to address the projects impacts. Minimum Requirement #2 — Construction Stormwater Pollution Prevention (SWPPP). A construction Stormwater Pollution Prevention Plan (SWPPP) has be incorporated into the site development plans. A summary of the site's erosion control measures that evaluates the typical 13 elements of a SWPPP are included in section E. The total site disturbance area of the project is greater than one acre, thus a formal Notice of Intent application for NPDES coverage will be made to the Department of Ecology. Minimum Requirement #3 —Source Control of Pollution. Specific source controls are not required for single family residential sites. General requirements for these sites include preventing the discharge of pollutants to the City's storm drainage system per Edmonds City Code Chapter 7.200 (Illicit Discharges). This includes common household items such as pesticides, herbicides, fertilizers, detergents and fluids from vehicle maintenance. Single family residences shall incorporate DOE's S411 BMPs for landscape and lawn vegetation management. Lawn and vegetation management can include control of objectionable weeds, insects, mold, bacteria, and other pests with pesticides. Examples include weed control on golf course lawns, access roads, and utility corridors and during landscaping; sap stain and insect control on lumber and logs; rooftop moss removal; killing nuisance rodents; fungicide application to patio decks, and residential lawn/plant care. It is possible to release toxic pesticides such as pentachlorophenol, carbamates, and organometallics to the environment by leaching and dripping from treated parts, container leaks, product misuse, and outside storage of pesticide contaminated materials and equipment. Poor management of the vegetation and poor application of pesticides or fertilizers can cause appreciable stormwater contamination. Minimum Requirement #4 — Preservation of Natural Drainage Systems and Outfalls. The site generally slopes in a northerly direction towards private properties; there are no concentrated flows or existing defined conveyance systems located onsite; any site runoff leaves the site as sheet -flow. Stormwater runoff RAMEngineering, Inc. RAM No. 17-038 Westhaven Stormwater Site Plan Report a Page A-1 Attachment 7 - PLN20180034 Packet Pg. 55 2.1.a leaving the site would eventually collect in the existing stormwater systems (pipe/catch basins) along the south side of 214th PI SW north of the site. The 2141h stormwater system routes runoff westerly under 98th Ave W and then southwesterly to the north side of 215th St SW (near the project site's northwest corner). The proposed development will reroute the stormwater discharge to the existing stormwater system within 98th Ave W that routes the water to the system along the north side of 2151h St SW merging with the system from 214th PI SW. The merg of the stormwater systems is about 550 ft from the site and thus are considered to be within the same threshold discharge basin (within % mile, thus no diversion). The project will maintain the existing downstream basin with only a minor sub -basin re -rout of stormwater flows. The site is located within the upper reach of the Shell Creek watershed basin per the City of Edmonds maps (see section Q. Minimum Requirement #5 — Onsite Stormwater Management. An updated site specific geotechnical evaluation of the site's soils demonstrates that infiltration is a not a viable option for stormwater management onsite due to relatively shallow depth to unweathered glacial till soils. Additionally, adequate flow length paths will most likely not be available for the individual building lots for any dispersion type BMP. Thus, only perforated stub -out connections and post construction soil amendment are proposed for onsite stormwater BMP. See civil site development plans and Section C for additional stormwater BMP evaluation and construction details. 5.6 Minimum Requirement #6 — Runoff Treatment. The project proposes to create/replace more than 5,000 sf of pollution -generation hard surface onsite. The project will create about 16,300 sf (10,000 sf onsite driveways + 6,300 sf of ROW road redevelopment) pollution generation hard surfaces. Thus, placement of general use approved basic water quality treatment stormwater filters are included the proposed site development. Design of the stormwater treatment filters are described in Section C below. 5.7 Minimum Requirement #7 — Flow Control. An onsite stormwater detention vault system will provide flow control of the site's stormwater runoff. The detention vault system has been designed to meet the flow control standards of a Category 2 project in a creek or lake basin (restrict the stormwater discharge duration for half the 2-year to 50-year storm events using a continuous storm event model). The detention vault has been sized using WWHM software; a full overview of the project's stormwater flow control measures are provided in section C below. 5.8 Minimum Requirement #8 — Wetland Protection. No wetlands are known to exist on or adjacent to the site. 5.9 Minimum Requirement #9 — Operation and Maintenance. An operation and maintenance summary is provided in section F. RAMEngineering, Inc.

The total site consists of about 86,657 sf (1.99 acres) and is currently occupied by three existing single-family residences with access driveways off 98th Ave SW. The existing houses are surrounded by grass lawn and landscape areas with several large mature trees throughout the site. The site is surrounded by single family residences to the north, east and south; 98th Ave SW to the west; and a stub public road of 215th St SW to the east boundary of the site (see aerial photo below). The site is generally slopes in the northerly direction in a range between 2% and 10%. No define drainage courses are found on -site and stormwater runoff would sheet flow northerly direction. No stream or wetlands were discovered on or immediately adjacent to the site. Additional discussion of the local drainage basin and downstream path is discussed in Section C of this report. Soils: In accordance with the project's site specific geotechnical engineering study by Earth Solutions NW, LLC the on -site soils consist of silty sand with gravel (USCS: SM) glacial till deposits. The subject site is underlain by glacial till deposits (Qvt, Vashon till soils). Full soils description is included in the project's site specific geotechnical engineering study by Earth Solutions NW, LLC. Aerial Photo (City of Edmonds GIS, 2015 photo): RAMEngineering, Inc.

The proposed project includes the construction of ten single-family residences and associated frontage improvements, driveways and utilities. All existing structures and hard surface onsite will be removed/replaced with the site development; landscaping and grass lawn around the new residence will stabilize the site upon building construction. The project proposes to create and/or replace 51,200 sf of hard surface with the complete site development, all existing onsite hard surface will be removed with the project site development. The following is a summary of the proposed new/replaced hard surface areas: Total Hard Surface New/Replaced Proposed = 51,200 sf (1.175 ac) Building Rooftop = 30,000 sf (3 lots @ 3,000 sf ea.) Uncovered Patio and Walk = 2,000 sf (10 lots @ 200 sf ea.) Individual Driveways = 8,000 sf (10 lots @ 800 sf ea.) Additional Panhandle Driveways = 2,000 sf Vault Access Raod = 1,800 sf ROW Frontage and Cul-de-sac = 6,300 sf ROW Sidewalk = 1,100 sf Upstream 98t" Ave SW ROW Net Run-on Area = 2,220 sf (0.051 ac) Total Impervious Surface (Site + Upstream) = 53,420 sf (1.226 ac) Total Pervious Surface (Lawn) = 37,757 sf (0.867 ac) An underground detention vault will be installed along the back (easterly) portion of lots 3 and 4 near the center of the site. The detention vault system will provide flow control of the project's stormwater runoff (Minimum Requirement #7). The hydrologic analysis uses WWHM2012 software to model historical storm events in the existing and proposed developed conditions. Per the City of Edmonds (DOE 2014) drainage manual, the project shall meet the site discharge duration for half the 2-year to 50-year storm events using a continuous storm event model (WWHM). The detention vault system will discharge to an Oldcastle Perk FilterTM located downstream of the control T_ structure; the stormwater filter system will provide basic water quality treatment. The stormwater flows N from the filter system will flow to a receiving catch basin on -site; the receiving catch basin will gravity � discharge to the public stormwater system along the east side of 981" Ave SW. a r a+ Due to the relatively shallow depth of the adjacent stormwater system in 98t" Ave SW the stormwater vault will utilize pumps to discharge the collected stormwater flows. All of the stormwater pumps and w pressurized line system shall be located on private property and covered by drainage easements (no .. r portion of the pump facilities will be located within public right-of-way). Additionally, a gravity overflow system will be provided between the detention vault and the gravity basin to accommodate the full E undetained 100-year peak flows (0.7595 cfs) to prevent flooding of the system in the event of pump system failure.

The site is located within the City of Edmonds Shell Creek watershed basin. The Shell Creek basin is a centralized urban basin that collects stormwater runoff from primarily residential areas in the City Edmonds and ultimately discharges flows northwesterly to Puget Sound (see attached watershed map). Site runoff leaves the site as sheet -flow runoff that flows in a northerly direction. Runoff leaving the site sheet -flows across the neighboring properties and enter the roadside ditch and culvert system along the south side of 2141h PI SW. The storm system along 214th PI SW directs stormwater west towards 98th Ave W (10th Ave S); at the intersection of 214th PI SW and 98th Ave W flows enter a pipe system (12") that directs the stormwater north under 214th PI SW and then west under 98th Ave W. The stormwater system continues in a southwesterly direction to 2151h St SW and flows westerly along private properties eventually reaching Pine St (north side). The system continues westerly along the north side of Pine St to 9th Ave S; the stormwater system is then directed northerly along 9th Ave S. Stormwater continues northerly along 9th Ave S and eventually discharges into Shell Creek about 0.85 miles downstream of the site. Shell Creek continues north/northwesterly and eventually discharges to the Puget Sound about 1.6 miles from the site. In the immediate vicinity of the project site some of the existing catch basin along 98th Ave SW have jumps between the intake and outlet elevations in which the outlet pipe are 0.1 to 0.2 ft above the inlet pipes. These are very minorjumps and the overall elevation drop between the connecting catch basins range from 1 ft to 2 ft and thus the minor jumps through the catch basins are insignificant to the overall capacity of the downstream system. Minor areas of run-on from the residential properties south of the site may occur; however, these flows are primarily from lawn areas and are considered insignificant. The downstream system consists of a man-made pipe and catch basin system within 0.85 miles of the site; 0.85 miles from the site the stormwater system discharge to Shell Creek. No apparent flooding or system inadequacies within downstream of the site were discovered during site visits or research of the downstream system.

A quadplex pump system has been designed to control the stormwater detention system discharge. The quadplex system is designed to initiate four different pumps and different stages to comply with the flow control stormwater control requirements of the project as demonstrated in the Stormwater Modeling Section above. The pump system consists of four (4) Zoeller 371 Series with 1.5" discharge with individual pump operating flow rate of 8.57 gpm (0.0191 cfs). Each pump is design to pump at the same rate so the system can alternate between pumps and extend the life of the pumps. Each pump will operate at 8.57 gpm (0.0191 cfs) against 17.5 ft of total head. Total head calculations and manufacturer documentation for the Zoeller 371 Series (including pump performance curves and specification) are provided below. Total Head: Total Head = Static Head + Dynamic Head Static Head = 97.4 ft. - 86.0 ft. = 11.4 ft. Dynamic Head, use the following equation to determine friction loss: (100)185 Q1852 f= 0.2083 C D 48655 i where: f = friction loss per 100 ft. of pipe C = flow coefficient 4 150 for PVC Q = 8.57 gpm D; = inside diameter of pipe, in. 4 1.5 in. 100 1.85 71.852f = .02083 r l,�s�s5= 0.73 ft. per 100 ft. of pipe \1501 (�8.5 1.5 Restricting Valve = 777 ft.

A geotechnical engineering study conducted for a civil engi- neer may not fulfill the needs of a construction contractor or even another civil engineer. Because each geotechnical engineering study is unique, each geotechnical engineering report is unique, prepared solelyfor the client. No one except you should rely on your geotechnical engineering report without first conferring with the geotechnical engineer who prepared it. And no one —notevenyou—should apply the report for any purpose or project except the one originally contemplated. Read the Full Report Serious problems have occurred because those relying on a geotechnical engineering report did not read it all. Do not rely on an executive summary Do not read selected elements only. A Geotechnical ElIg ff eelliaig Report Is Based on A Unique Set of Piloject-Specific Factors Geotechnical engineers consider a number of unique, project -specific fac- tors when establishing the scope of a study. Typical factors include: the client's goals, objectives, and risk management preferences; the general nature of the structure involved, its size, and configuration; the location of the structure on the site; and other planned or existing site improvements, such as access roads, parking lots, and underground utilities. Unless the geotechnical engineer who conducted the study specifically indicates oth- erwise, do not rely on a geotechnical engineering report that was: • not prepared for you, V. not prepared for your project, not prepared for the specific site explored, or • completed before important project changes were made. Typical changes that can erode the reliability of an existing geotechnical engineering report include those that affect: the function of the proposed structure, as when it's changed from a parking garage to an office building, or from a light industrial plant to a refrigerated warehouse, • elevation, configuration, location, orientation, or weight of the proposed structure, composition of the design team, or • project ownership. As a general rule, always inform your geotechnical engineer of project changes —even minor ones —and request an assessment of their impact. Geotechnical engineers cannot accept responsibility or liability for problems that occur because their reports do not consider developments of which they were not informed. Subsurface Conditions Can Change A geotechnical engineering report is based on conditions that existed at the time the study was performed. Do not rely on a geotechnical engineer- ing reportwhose adequacy may have been affected by: the passage of time; by man-made events, such as construction on or adjacent to the site; or by natural events, such as floods, earthquakes, or groundwater fluctua- tions. Always contact the geotechnical engineer before applying the report to determine if it is still reliable. A minor amount of additional testing or analysis could prevent major problems. Most Geotechnical Findings Are Professional Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. Geotechnical engi- neers review field and laboratory data and then apply their professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ —sometimes significantly — from those indicated in your report. Retaining the geotechnical engineer who developed your report to provide construction observation is the most effective method of managing the risks associated with unanticipated conditions. A Report's Recommendations Are Not Final Do not overrely on the construction recommendations included in your report. Those recommendations are not final, because geotechnical engi- neers develop them principally from judgment and opinion. Geotechnical engineers can finalize their recommendations only by observing actual a Attachment 7 - PLN20180034 Packet Pg. 85 2.1.a subsurface conditions revealed during construction. The geotechnical engineer who developed your report cannot assume responsibility or liability for the report's recommendations if that engineer does not perform construction observation. A Geotechnical Engineering Report Is Subject to Misinterpretation Other design team members' misinterpretation of geotechnical engineering reports has resulted in costly problems, Lower that risk by having your geo- technical engineer confer with appropriate members of the design team after submitting the report. Also retain your geotechnical engineer to review perti- nent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering report. Reduce that risk by having your geotechnical engineer participate in prebid and preconstruction conferences, and by providing construction observation. Do Not Redraw the Engineer's Logs Geotechnical engineers prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included in a geotechnical engineering report should neverbe redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk. Give Contractors a Complete Report and Guidance Some owners and design professionals mistakenly believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give con- tractors the complete geotechnical engineering report, but preface it with a clearly written letter of transmittal. In that letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is limited; encourage them to confer with the geotechnical engineer who prepared the report (a modest fee may be required) and/or to conduct additional study to obtain the specific types of information they need or prefer, A prebid conference can also be valuable. Be sure contrac- tors have sufficient time to perform additional study. Only then might you be in a position to give contractors the best information available to you, while requiring them to at least share some of the financial responsibilities stemming from unanticipated conditions. Read Responsibility Provisions Closely Some clients, design professionals, and contractors do not recognize that geotechnical engineering is far less exact than other engineering disci- plines. This lack of understanding has created unrealistic expectations that have led to disappointments, claims, and disputes_ To help reduce the risk of such outcomes, geotechnical engineers commonly include a variety of explanatory provisions in their reports. Sometimes labeled "limitations" many of these provisions indicate where geotechnical engineers' responsi- bilities begin and end, to help others recognize their own responsibilities and risks. Read these provisions closely. Ask questions. Your geotechnical engineer should respond fully and frankly. Geoenvironmental Concerns Are Not Covered The equipment, techniques, and personnel used to perform a geoenviron- mental study differ significantly from those used to perform a geolechnical study. For that reason, a geotechnical engineering report does not usually relate any geoenvironmental findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Unanticipated environmental problems have led to numerous project failures. If you have not yet obtained your own geoen- vironmental information, ask your geotechnical consultant for risk man- agement guidance. Do not rely on an environmental report prepared for someone else. Obtain Professional Assistance To Deal with Mold Diverse strategies can be applied during building design, construction, operation, and maintenance to prevent significant amounts of mold from growing on indoor surfaces. To be effective, all such strategies should be devised for the express purpose of mold prevention, integrated into a com- prehensive plan, and executed with diligent oversight by a professional mold prevention consultant. Because just a small amount of water or moisture can lead to the development of severe mold infestations, a num- ber of mold prevention strategies focus on keeping building surfaces dry. While groundwater, water infiltration, and similar issues may have been addressed as part of the geotechnical engineering study whose findings are conveyed in -this report, the geotechnical engineer in charge of this project is not a mold prevention consultant; none of the services per- formed in connection with the geotechnical engineer's study were designed or conducted for the purpose of mold preven- tion. Proper implementation of the recommendations conveyed in this report will not of itself he sufficient to prevent mold from growing in or on the structure involved.

To complete the scope of services detailed in our proposal PES-5553 dated August 25, 2017, we performed the following: • Completing test pits for purposes of characterizing site soil conditions; Completing laboratory testing of soil samples collected at the test pit locations; Conducting engineering analyses, and; Preparation of this report. The following documents and resources were reviewed as part of our report preparation; Feasibility Exhibit, prepared by RAM Engineering, Inc., dated July 28, 2017; L O ® Geologic Map of the Edmonds East and Part of the Edmonds West Quadrangle, Washington, prepared by James P. Minard, dated 1983; U) Stormwater Management Manual for Western Washington, prepared by Department of M Ecology, as amended, December 2014; o 00 Edmonds City Code, Chapter 23.80 (Geologically Hazardous Areas), and; z J Online Web Soil Survey (WSS) resource, provided by United States Department of a Agriculture (USDA), Natural Resources Conservation Services. Project Description w r We understand the existing single-family residential structure will be demolished and five new single-family residential structures will be constructed. We anticipate grading activities will include cuts and fills to establish the planned building alignments. Based on the existing grades, we estimate cuts to establish building pad and foundation subgrade elevations will be Q on the order of three to five feet. However, grading plans were not available at the time this report was prepared. Site improvements will also include underground utility installations. Earth Solutions NW, LLC Attachment 7 - PLN20180034 Packet Pg. 90 2.1.a Select Homes, Inc. ES-5553 October 13, 2017 Page 2 Based on our previous experience with similar projects, the proposed residential structures will likely be two to three stories in height and constructed utilizing relatively lightly -loaded wood framing supported on conventional foundations. Perimeter footing loads of about one to two kips per lineal foot are expected. Slab -on -grade loading is anticipated to be approximately 150 pounds per square foot (psf). If the above design assumptions are incorrect or change, ESNW should be contacted to review the recommendations in this report. ESNW should review the final design to verify the geotechnical recommendations provided in this report have been incorporated into the plans. SITE CONDITIONS Surface The subject site located at 21511 - 98th Avenue West in Edmonds, Washington, as illustrated on the Vicinity Map (Plate 1). The site consists of one residential tax parcel (Snohomish County parcel number 27032500107900) totaling approximately 1.0 acres of land area. The property is currently developed with a single-family residence and associated improvements. The site is surrounded to the north, south, and east by single-family residences, and to the west by 98th Avenue West. Site topography is relatively level, with total elevation change of approximately five feet across the site. Vegetation consists primarily of field grass throughout the property. Subsurface An ESNW representative observed, logged, and sampled five test pits, excavated at accessible locations within the proposed development area, on September 7, 2017, using a mini-trackhoe and operator provided by the client. The test pits were completed for purposes of assessing soil conditions, classifying site soils, and characterizing groundwater conditions within the proposed development area. The approximate locations of the test pits are depicted on Plate 2 (Test Pit Location Plan). Please refer to the test pit logs provided in Appendix A for a more detailed description of subsurface conditions. Representative soil samples collected at the test pit locations were analyzed in general accordance with the Unified Soil Classification System (USCS) and United States Department of Agriculture (USDA) methods and procedures. Topsoil and Fill Topsoil was generally encountered within the upper two to four inches of existing grades at the a test pit locations. The topsoil was characterized by brown color, the presence of fine organic IL material, and small root intrusions. Fill deposits were not encountered at the test pit locations during our fieldwork. Fill may be present, however, within proximity to existing structural E improvements. Where fill is encountered during construction, ESNW should be consulted to W evaluate the suitability for reuse as structural fill. E a Earth Solutions NW, LLC Attachment 7 - PLN20180034 Packet Pg. 91 2.1.a Select Homes, Inc. October 13, 2017 Native Soil ES-5553 Page 3 Underlying topsoil, native soils were characterized primarily as silty sand (Unified Soil Classification System: SM), consistent with the typical makeup of Vashon till. The upper one - and -one-half to four feet of the Vashon till was characterized as "weathered". Unweathered, dense Vashon till was encountered at -depth, extending to the maximum exploration depth of about seven -and -one-half feet below the existing ground surface (bgs). Geologic Setting The referenced geologic map resource identifies Vashon till (Qvt) across the site and surrounding areas. The referenced WSS resource identifies Alderwood-Urban land complex (Map Unit Symbol: 5) across the site and surrounding areas. The Alderwood series was formed in glacial till plains. Based on our field observations, native soils on site are generally consistent with the geologic setting outlined in this section. Groundwater Groundwater seepage was not observed during our fieldwork on September 7, 2017. Groundwater seepage rates and elevations fluctuate depending on many factors, including precipitation duration and intensity, the time of year, and soil conditions. In general, groundwater elevations and flow rates are higher during the winter, spring and early summer months. In this respect, we anticipate groundwater seepage to be encountered in a perched condition at the contact between the upper weathered and underlying uweathered glacial till soil during the wet season. GEOLOGICALLY HAZARDOUS AREAS ASSESSMENT As part of this geotechnical engineering study, the referenced chapter of the Edmonds City Code was reviewed. Based on our investigation and review, there are no geologically hazardous areas present on or adjacent to the site. DISCUSSION AND RECOMMENDATIONS General Based on the results of our study, construction of the proposed residential structures at the r subject site is feasible from a geotechnical standpoint. The primary geotechnical considerations associated with the proposed development include foundation support, temporary excavations, low impact development feasibility, and the suitability of the on -site soils LUX for use as structural fill. a) E a Earth Solutions NW, LLC Attachment 7 - PLN20180034 Packet Pg. 92 2.1.a Select Homes, Inc. ES-5553 October 13, 2017 Page 4 The proposed structures can be supported on conventional spread and continuous foundations bearing on undisturbed competent native soil, recompacted native soil, or structural fill. Competent soils suitable for support of foundations should be encountered beginning at depths of roughly one to three feet below existing grades across the majority of the site. Slab -on -grade floors should be supported on dense native soil, re -compacted native soil, or structural fill. Organic material exposed at subgrade elevations must be removed below design elevation and grades restored with structural fill. Where loose, organic or other unsuitable materials are encountered at or below the footing subgrade elevation, the material should be removed and replaced with structural fill, as necessary. This study has been prepared for the exclusive use of Select Homes, Inc. and their representatives. No warranty, expressed or implied, is made. This study has been prepared in a manner consistent with the level of care and skill ordinarily exercised by other members of the profession currently practicing under similar conditions in this area. Site Prenaratio►7 and Earthwork Based on the existing topography, we anticipate grading for the project will involve cuts of up to three to five feet to establish building pad and foundation subgrade alignments. Silt fencing and temporary erosion control measures should be placed along the perimeter of the site prior to beginning grading activities. Temporary Erosion Control Temporary construction entrances, consisting of at least six inches of quarry spalls, can be considered in order to minimize off -site soil tracking and to provide a temporary road surface. Silt fences should be placed along the margins of the property. Interceptor swales and a temporary sediment pond may be necessary for control of surface water during construction. Erosion control measures should conform to the Washington State Department of Ecology (DOE) and City of Edmonds standards. In -situ Soils From a geotechnical standpoint, the soils encountered at the test pit locations are generally N suitable for use as structural fill. However, successful use of the on -site soils will largely be J dictated by the moisture content of the soils at the time of placement and compaction. The site a soils were generally in a damp to moist condition at the time of the exploration on September 7, r 2017. M x w w Q Earth Solutions NW, LLC Attachment 7 - PLN20180034 Packet Pg. 93 2.1.a Select Homes, Inc. ES-5553 October 13, 2017 Page 5 Based on the conditions encountered during our fieldwork, the site soils will generally have a moderate to high sensitivity to moisture. During periods of dry weather, the on -site soils should generally be suitable for use as structural fill, provided the moisture content is at or near the optimum level at the time of placement. Successful placement and compaction of the on -site soils during periods of precipitation will be difficult. If the on -site soils cannot be successfully compacted, the use of an imported soil may be necessary. Imported soil intended for use as structural fill should consist of a well -graded granular soil with a moisture content that is at or near the optimum level. During wet weather conditions, imported soil intended for use as structural fill should consist of a well -graded granular soil with a fines content of 5 percent or less defined as the percent passing the Number 200 sieve, based on the minus three-quarter inch fraction. Structural Fill Structural fill is defined as compacted soil placed in foundation, slab -on -grade, and roadway areas. Fills placed to construct permanent slopes and throughout retaining wall and utility trench backfill areas are also considered structural fill. Soils placed in structural areas should be placed in loose lifts of 12 inches or less and compacted to a relative compaction of 95 percent, based on the laboratory maximum dry density as determined by the Modified Proctor Method (ASTM D-1557 Excavations and Slopes The Federal Occupation Safety and Health Administration (OSHA) and the Washington Industrial Safety and Health Act (WISHA) provide soil classification in terms of temporary slope inclinations. Loose native soil, existing fill, and soil where groundwater seepage is encountered are classified as Type C soils by OSHA/WISHA. Temporary slopes over four feet in height in Type C soils must be sloped no steeper than 1.5H:1V (Horizontal:Ver#ical). Dense to very dense glacial till soils are classified as Type A soils by OSHAANISHA. Temporary slopes over four feet in height in Type A soils must be sloped no steeper than 0.75H:1V. The presence of perched groundwater may cause caving of the temporary slopes due to seepage forces. ESNW should observe site excavations to confirm the soil type and allowable slope inclination are appropriate for the soil exposed by the excavation. If the recommended temporary slope inclination cannot be achieved, temporary shoring may be necessary to support excavations. Permanent slopes should maintain a gradient of 2H:1V, or flatter, and should be planted with a vegetation to enhance stability and to minimize erosion. A representative of ESNW should r observe temporary and permanent slopes to confirm the slope inclinations are suitable for the exposed soil conditions, and to provide additional excavation and slope recommendations, as x w necessary. r E a Earth Solutions Nw, LLC Attachment 7 - PLN20180034 Packet Pg. 94 2.1.a Select Homes, Inc. October 13, 2017 Foundations ES-5553 Page 6 The proposed residential structures can be supported on conventional spread and continuous footings bearing on competent native soil, recompacted native soil, or structural fill. Based on the soil conditions encountered at the test pit locations, competent native soils suitable for support of foundations should be encountered beginning at depths of roughly one to three feet below existing grades. Where loose or unsuitable soil conditions are observed at foundation subgrade elevations, compaction of the soils to the specifications of structural fill, or overexcavation and replacement with granular structural fill will be necessary. Organic material exposed at foundation subgrade elevations must be removed and grades restored with structural fill. Provided the structures will be supported as described above, the following parameters can be used for design of the new foundations: E • Allowable soil bearing capacity 2,500 psf L a 40 Passive earth pressure 300 pcf (equivalent fluid) • Coefficient of friction 0.40 A one-third increase in the allowable soil bearing capacity can be assumed for short-term wind and seismic loading conditions. c With structural loading as expected, total settlement in the range of one inch is anticipated, with E differential settlement of about one-half inch. The majority of the settlements should occur during construction, as dead loads are applied. Seismic Design Considerations L The 2015 IBC recognizes ASCE for seismic site class definitions. If the project will be permitted $ under the 2015 IBC, in accordance with Table 20.3-1 of ASCE, Minimum Design Loads for i Buildings and Other Structures, Site Class D, should be used for design. a In our opinion, the site is not susceptible to liquefaction. The soil relative density and the o absence of an established, shallow groundwater table are the primary bases for this opinion. 40 0 Slab -On -Grade Floors cm z J Slab -on -grade floors should be supported on a firm and unyielding subgrade consisting of a competent native soil or at least 12 inches of structural fill. Unstable or yielding areas of the subgrade should be recompacted or overexcavated and replaced with suitable structural fill Z prior to construction of the slab. A capillary break consisting of a minimum of four inches of w free -draining crushed rock or gravel should be placed below the slab. The free -draining material should have a fines content of 5 percent or less defined as the percent passing the Number 200 sieve, based on the minus three-quarters inch fraction. In areas where slab moisture is undesirable, installation of a vapor barrier below the slab should be considered. If c used, the vapor barrier should consist of a material specifically designed to function as a vapor a barrier and should be installed in accordance with the manufacturer's specifications.

October 13, 2017 Retaining Walls ES-5553 Page 7 If retaining walls will be utilized, they should be designed to resist earth pressures and applicable surcharge loads. The following parameters can be used for retaining wall design: Active earth pressure (yielding condition) At -rest earth pressure (restrained condition) Traffic surcharge (passenger vehicles) • Passive earth pressure R Coefficient of friction Seismic surcharge "Where H equals retained height 35 pcf 55 pcf 70 psf (rectangular distribution) 300 pcf 0.40 6H* Where sloping or other surcharge conditions will be present, supplement recommendations and design earth pressure values should be provided by ESNW. Drainage should be provided behind retaining walls such that hydrostatic pressures do not develop. If drainage is not provided, hydrostatic pressures should be included in the wall design. Retaining walls should be backfilled with free -draining material that extends along the height of the wall, and a distance of at least 18 inches behind the wall. The upper one foot of the wall backfill can consist of a less permeable soil, if desired. A perforated drain pipe should be placed along the base of the wall, and should be connected to an approved discharge location. A typical retaining wall drainage detail is provided as Plate 3. Drains e Groundwater seepage was not observed during our fieldwork on September 7, 2017. Water seepage is possible in site excavations, particularly in the winter, spring and early summer N months. Temporary measures to control groundwater seepage and surface water runoff during Z construction will likely involve passive elements such as interceptor trenches and sumps, as a necessary. Surface water should not be allowed to runoff over sloped areas and should not be allowed to pond near the top of sloped areas or retaining structures. x Surface grades must be designed to direct water away from buildings. The grade adjacent to "U buildings should be sloped away from the buildings at a gradient of at least 2 percent for a horizontal distance of ten feet. In our opinion, perimeter footing drains should be installed at or below the invert of the building footings. A typical footing drain detail is provided on Plate 4 of a w this report.

October 13, 2017 On -site Stormwater Management ES-5553 Page 8 Pursuant to City of Edmonds stormwater management requirements, implementation of on -site stormwater BMPs are required for proposed developments in accordance with specified thresholds, standards, and lists. The intent of BMP implementation is to infiltrate, disperse, and retain stormwater runoff on site to the extent feasible. The table below summarizes our evaluation of low impact development methods, as outlined in the referenced stormwater manual, from a geotechnical standpoint. It is instructed in the referenced stormwater manual that BMPs are to be considered in the order listed (from top to bottom) for each surface type, and the first BMP that is determined to be viable should be used. For completeness, however, we have evaluated each listed BMP for the proposed surface types. r t X W r C d E t v R r .r Q Earth Solutions NW, LLC Attachment 7 - PLN20180034 Packet Pg. 97 2.1.a Select Homes, Inc.

October 13, 2017 Utility Trench Support and Backfill ES-5553 Page 10 In our opinion, the soils observed at the test pit locations are generally suitable for support of utilities. In general, the soils observed at the test pit locations should be suitable for use as structural backfill in the utility trench excavations, provided the soil is at or near the optimum moisture content at the time of placement and compaction. Moisture conditioning of the soils may be necessary at some locations prior to use as structural fill. Utility trench backfill should be placed and compacted to the specifications of structural fill provided in this report, or to the applicable requirements of the City of Edmonds. Pavement Sections The performance of site pavements is largely related to the condition of the underlying subgrade. To ensure adequate pavement performance, the subgrade should be in a firm and unyielding condition when subjected to proofrolling with a loaded dump truck. Structural fill in pavement areas should be compacted to the specifications detailed in the Site Preparation and Earthwork section of this report. It is possible that soft, wet, or otherwise unsuitable subgrade areas may still exist after base grading activities. Areas of unsuitable or yielding subgrade conditions may require remedial measures such as overexcavation and replacement with structural fill or thicker crushed rock sections prior to pavement. For relatively lightly loaded pavements subjected to automobiles and occasional truck traffic, the following sections can be considered for preliminary design: Is Two inches of hot mix asphalt (HMA) placed over four inches of crushed rock base (CRIB), or; 0 Two inches of HMA placed over three inches of asphalt treated base (ATB). The HMA, CRIB and ATB materials should conform to WSDOT specifications. .r a Earth Solutions NW, LLC Attachment 7 - PLN20180034 Packet Pg. 99 2.1.a Select Homes, Inc.

CONSTRUCTION SWPPP REQUIREMENTS: The project will require grading to construct the proposed building and utilities (including the stormwater control facilities). Standard erosion control measures are proposed to be used during construction. The primary erosion and sediment control BMP during construction will be proper soil stabilization methods. Exposed soils shall be stabilized by application of effective BMPs that protect the soil from the erosive forces of raindrops, flowing water, and wind. Applicable practices include, but not limited to, temporary and permanent seeding, sodding, mulching, plastic covering, erosion control fabrics, matting, the early application of gravel base on areas to be paved, and dust control. The contractor shall select a soil stabilization method best suited for the particular situation. Stock piles must be stabilized and protected with sediment trapping measures. In addition, site containment of exposed soils shall be sustained by using silt fence barriers along the down -slope boundaries of the site's disturbance areas. See the site development plan for details. Construction Stormwater Pollution Prevention Plan ISWPPPj; The following is a summary of the site's erosion control measures that evaluates the typical DOE 13 elements of a SWPPP: Element 1: Mark Clearing Limits: Clearing limits have been delineated on the engineering site development plans. Element 2: Establish Construction Access: A construction access has been delineated on the engineering site development plans. Element 3: Control Flow Rates: During construction silt fencing will provide attenuation of site runoff and upon project completion and stabilization (established lawns and landscape of exposed soils). Element 4: Install Sediment Controls: Filter fabric fence has been delineated and detailed on the engineering site development plans. At a minimum, silt fence will be installed along the down gradient perimeter of the disturbed area that will receive sediment -laden runoff. Element 5: Stabilize Soils: Soils will be stabilized per the TESC notes listed on the engineering site development plans. Element 6: Protect Slopes: Exposed slopes shall be stabilized per the TESC notes listed on the engineering site development plans. Element 7: Protect Drain Inlets: Drain inlet protection will be installed on all catch basins that will receive sediment -laden runoff. See the engineering site development plans for locations and detail. Element 8: Stabilize Channels and Outlets: This element is not applicable since there are no temporary channels or outlets proposed. Element 9: Control Pollutants: Pollutants shall be managed as described in the TESC notes listed on the engineering site development plans. RAM Engineering, Inc. Westhaven RAM No. 17-038 Stormwater Site Plan Report Page E-1 Attachment 7 - PLN20180034 Packet Pg. 115 2.1.a Element 10: Control De -Watering: Highly turbid or contaminated de -watering water shall be handled separately from stormwater. The water from all de -watering systems for trenches and foundations shall be treated or disposed prior to discharging from the site. Element 11: Maintain BMPs: BMPs shall be maintained and removed at the end of the project as follows: i. All temporary and permanent erosion and sediment control BMPs shall be inspected, maintained and repaired in accordance with the Drainage Manual or as approved or required by the City to assure continued performance of their intended function in accordance with BMP specifications. ii. The applicant may remove temporary BMPs when they are no longer needed. iii. All temporary erosion and sediment control BMPs shall be removed within 30 days after construction is completed and the City has determined that the site is stabilized. Element 12: Manage the Project: The owner of the site is responsible for managing the installation and maintenance of the site BMPs. Element 13. Protect Low Impact Development BMPs: No LID stormwater BMPs are proposed. Conclusion: The total site disturbance area of the project is greater than one acre, thus a formal Notice of Intent application for NPDES coverage will be made to the Department of Ecology prior to the start of construction. The final site development construction plans include specific grading and drainage improvement notes and details. With proper installation, maintenance and inspections of the proposed construction the project should have minimal impact to the surrounding environment. RAM Engineering, Inc RAM No. 17-038 Westhaven Stormwater Site Plan Report Page E-2 Attachment 7 - PLN20180034 Packet Pg. 116 2.1.a F. OPERATION AND MAINTENANCE GUIDELINES: These guidelines are intended to provide operation and maintenance instructions for the project's storm drainage control facilities. The owner is responsible for maintenance of storm drainage facilities within the property (private property owner system); the owner is not responsible for maintenance within the public right-of-way (City system). Private property owners are responsible for properly maintaining the stormwater infrastructure on their property to ensure it operates as designed. The City has developed an inspection program to ensure private property owners are properly maintaining their stormwater systems. This manual is not comprehensive; although it explains the intended operation of the various components of the drainage system, and suggests a routine of inspection and maintenance, it cannot anticipate every problem. Once a historical record of maintenance is established, it may be prudent to alter the routine. It is recommended that maintenance records be kept, and that the records be reviewed periodically. The onsite detention vault system, control structure, storm filter, storm pumps, junction catch basins, and conveyance pipes are to be privately maintained by the project residences (all 10 lots). Maintenance shall include the removal of sediment from the detention vault system, using a vactor truck or equally effective method. Regular inspections of the control structure within the catch basin shall be conducted to detect if non -routine maintenance is required due to sediment or debris blocking or clogging the fixed orifice or standpipe inlet. Regular sediment removal from the catch basins with a vactor truck or equally effective method shall be conducted as determined by regular inspections. Regular inspection and maintenance of the storm filter should occur according to the attached maintenance tables from the Washington State Department of Ecology Stormwater Manual (Volume V) and the attached maintenance guide from Oldcastle Stormwater Solutions Perk FilterT"' system and storm control pump system are also attached on the following pages. Semi-annual inspections shall be conducted to ensure proper operations of the drainage system. The inspections should occur prior to the winter rain season (Oct/Nov), leaving sufficient time to correct any detected maintenance problems, and at the end of the season (April/May) to determine the effect of the season's runoff. Once a historical basis is developed the frequency of inspection may be modified as necessary. Sediment can build up inside control structures and catch basins, blocking or restricting flow to the inlet. To prevent this problem, these structures should be routinely cleaned. Regular inspections of control structures should be conducted to detect the need for non -routine cleanout. MAINTENANCE REQUIREMENTS ECDC Section 18.30.090 requires privately -owned stormwater management facilities, such as LID BMPs be properly maintained. The owner of the property is the responsible party for such maintenance. The system must be kept in good working order. The entire system should be inspected once per year. An improperly maintained BMP may cause private property or street Flooding. Contact the City Engineering Division for maintenance information. The City may make periodic inspections of BMPs to ensure they are operating properly. ECDC Section 18.30.100 contains the enforcement provisions the City can use to ensure the system is properly maintained. RAMEngineering, Inc.

Impervious surfaces and other urban and suburban landscapes generate a variety of contaminants that can enter stormwater and pollute downstream receiving waters. The PerkFilter is a media -filled cartridge filtration device designed to capture and retain sediment, gross solids, metals, nutrients, hydrocarbons, and trash and debris. As with any stormwater treatment system, the PerkFilter requires regular periodic maintenance to sustain optimum system performance. Function The PerkFilter is a water quality treatment system consisting of three chambers: an inlet chamber, a filter cartridge treatment chamber, and an outlet chamber (Figure 1). Stormwater runoff enters the inlet chamber through an inlet pipe, curb opening, or grated inlet. Gross solids are settled out and floating trash and debris are trapped in the inlet chamber. Pretreated flow is then directed to the treatment chamber through an opening in the baffle wall between the inlet chamber and treatment chamber.The treatment chamber contains media -filled filter cartridges (Figure 2) that use physical and chemical processes to remove pollutants. During a storm event, runoff pools in the treatment chamber before passing radially through the cylindrical cartridges from the outside surface, through the media for treatment, and into the center of the cartridge. At the center of the cartridge is a center tube assembly designed to distribute the hydraulic load evenly across the surface of the filter cartridge and control the treatment flow rate. The center tube assembly discharges treated flow through the false floor and into the outlet chamber. A draindown feature built into each cartridge allows the treatment chamber to dewater between storm events. !n[�t clramber� lnletp+pe Precast concrete vault Filter cartridge treatment rhamber Bypass assembly Figure 1.

The bypass assembly routes peak flow from the inlet chamber directly to the outlet chamber, bypassing the treatment chamber to prevent sediment and other captured pollutants from being scoured and re -entrained by high flow. Treated flow and bypass flow merge in the outlet chamber for discharge by a single outlet pipe. Vent tube Outermedio layer Center tube assem* Inner media layer Outer screen Connection to outlet chamber (with dromdown) Figure 2. Schematic of the PerkFilter cartridge. Configuration The PerkFilter structure may consist of a vault, manhole, or catch basin configuration. Catch basin units may be fabricated from concrete or steel. Internal components including the PerkFilter cartridges are manufactured from durable plastic and stainless steel components and hardware. All cartridges are 18 inches in diameter and are available in two heights:l2-inch and 18-inch. Cartridges may be used alone or may be stacked (Figure 3) to provide 24-inch and 30-inch combinations. The capacity of each cartridge or cartridge combination is dictated by the allowable operating rate of the media and the outer surface area of the cartridge. Thus, taller cartridges have greater treatment capacity than shorter cartridges but they also require more hydraulic drop across the system. Cartridges may be filled with a wide variety of media but the standard mix is composed of zeolite, perlite, and carbon (ZPC). Access to an installed PerkFilter system is typically provided by ductile iron castings or hatch covers. The location and number of access appurtenances is dependent on the size and configuration of the system.

Maintenance prevents excessive pollutant buildup that can limit system performance by reducing the operating capacity and increasing the potential for scouring of pollutants during periods of high flow. Inspection and Maintenance Frequency The PerkFilter should be inspected on a regular basis, typically twice per year, and maintained as required. Initially, inspections of a new system should be conducted more frequently to help establish an appropriate site -specific inspection frequency. The maintenance frequency will be driven by the amount of runoff and pollutant loading encountered by a given system. In most cases, the optimum maintenance interval will be one to three years. Inspection and maintenance activities should be performed only during dry weather periods. Inspection Equipment The following equipment is helpful when conducting PerkFilter inspections: • Recording device (pen and paper form, voice recorder, Wad, etc.) • Suitable clothing (appropriate footwear, gloves, hardhat, safety glasses, etc.) • Traffic control equipment (cones, barricades, signage, flagging, etc.) • Socket and wrench for bolt -down access covers • Manhole hook or pry bar • Flashlight • Tape measure • Measuring stick or sludge sampler • Long -handled net (optional) Inspection Procedures PerkFilter inspections are visual and may be conducted from the ground surface without entering the unit. To complete an inspection, safety measures including traffic control should be deployed before the access covers are removed. Once the covers have been removed, the following items should be checked and recorded (see form provided at the end of this document) to determine whether maintenance is required: • Inspect the internal components and note whether there are any broken or missing parts. In the unlikely event that internal parts are broken or missing, contact Oldcastle Stormwater Solutions at (800) 579-8819 to determine appropriate corrective action. • Note whether the inlet pipe is blocked or obstructed. The outlet pipe is covered by a removable outlet hood and cannot be observed without entering the unit.

The significance of accumulated floating trash and debris is a matter of judgment. A long -handled net may be used to retrieve the bulk of trash and debris at the time of inspection if full maintenance due to accumulation of floating oils or settled sediment is not yet warranted. Observe, quantify, and record the accumulation of oils in the inlet chamber. The significance of accumulated floating oils is a matter of judgment. However, if there is evidence of an oil or fuel spill, immediate maintenance by appropriate certified personnel is warranted. Observe, quantify, and record the average accumulation of sediment in the inlet chamber and treatment chamber. A calibrated dipstick, tape measure, or sludge sampler may be used to determine the amount of accumulated sediment in each chamber. The depth of sediment may be determined by calculating the difference between the measurement from the rim of the PerkFilter to the top of the accumulated sediment and the measurement from the rim of the PerkFilter to the bottom of the PerkFilter structure. Finding the top of the accumulated sediment below standing water takes some practice and a light touch, but increased resistance as the measuring device is lowered toward the bottom of the unit indicates the top of the accumulated sediment. Finally, observe, quantify, and record the amount of standing water in the treatment chamber around the cartridges. If standing water is present, do not include the depth of sediment that may have settled out below the standing water in the measurement. Maintenance Triggers Maintenance should be scheduled if any of the following conditions are identified during the inspection: • Internal components are broken or missing. • Inlet piping is obstructed. • The accumulation of floating trash and debris that cannot be retrieved with a net and/or oil in the inlet chamber is significant. • There is more than 6"of accumulated sediment in the inlet chamber. • There is more than 4"of accumulated sediment in the treatment chamber. • There is more than 4"of standing water in the treatment chamber more than 24 hours after end of rain event. - A hazardous material release (e.g. automotive fluids) is observed or reported. • The system has not been maintained for 3 years (wet climates) to S years (dry climates). Maintenance Equipment The following equipment is helpful when conducting PerkFilter maintenance: • Suitable clothing (appropriate footwear, gloves, hardhat, safety glasses, etc.) • Traffic control equipment (cones, barricades, signage, flagging, etc.) • Socket and wrench for bolt -down access covers Manhole hook or pry bar • Confined space entry equipment, if needed VI F. : 114J? 11 J RAM No. 17-038 Stormwater Site Plan Report a Attachment 7 - PLN20180034 Page F-12 Packet Pg. 128 2.1.a PerkFiiter i Inspection and Maintenance Guide Flashlight • Tape measure • WW socket and wrench to remove hold-down struts and "niter cartridge tops • Replacement filter cartridges • Vacuum truck with water supply and water jet Contact Oldcastle Stormwater Solutions at (800) 579-8819 for replacement filter cartridges. A lead time of four weeks is recommended. Maintenance Procedures Maintenance should be conducted during dry weather when no flow is entering the system. Confined space entry is necessary to maintain vault and manhole PerkFiiter configurations. Only personnel that are OSHA Confined Space Entry trained and certified may enter underground structures. Confined space entry is not required for catch basin PerkFiiter configurations. Once safety measures such as traffic control are deployed, the access covers may be removed and the following activities may be conducted to complete maintenance: • Remove floating trash, debris, and oils from the water surface in the inlet chamber using the extension nozzle on the end of the boom hose of the vacuum truck. Continue using the vacuum truck to completely dewater the inlet chamber and evacuate all accumulated sediment from the inlet chamber. Some jetting may be required to fully remove sediment.The inlet chamber does not need to be refilled with water after maintenance is complete.The system will fill with water when the next storm event occurs. • Remove the hold-down strut from each row of filter cartridges and then remove the top of each cartridge (the top is held on by four 9/1 b" bolts) and use the vacuum truck to evacuate the spent media. When empty, the spent cartridges may be easily lifted off their slip couplers and removed from the vault.The couplers may be left inserted into couplings cast into the false floor to prevent sediment and debris from being washed into the outlet chamber during washdown. • Once all the spent cartridges have been removed from the structure, the vacuum truck may be used to evacuate all accumulated sediment from the treatment chamber. Some jetting may be required to fully remove sediment. Take care not to wash sediment and debris through the openings in the false floor and into the outlet chamber. All material removed from the PerkFiiter during maintenance including the spent media must be disposed of in accordance with local, state, and/or federal regulations. In most cases, the material may be handled in the same manner as disposal of material removed from sumped catch basins or manholes. • Place a fresh cartridge in each cartridge position using the existing slip couplers and urethane bottom caps. If the vault is equipped with stacked cartridges, the existing outer and inner interconnector couplers must be used between the stacked cartridges to provide hydraulic connection. Transfer the existing vent tubes from the spent cartridges to the fresh cartridges. Finally, refit the struts to hold the fresh cartridges in place. • Securely replace access covers, as appropriate. • Make arrangements to return the empty spent cartridges to Oldcastle Stormwater Solutions. ul�Oio 7 ?1Jrr.2C15 VI RAM No. 17-038 Stormwater Site Plan Report a Attachment 7 - PLN20180034 Page F-13 Packet Pg. 129 2.1.a PerkFllter I Inspection and Maintenance Guide Location Structure Configuration and Size: Inspection Date ❑ Vault feet x feet ❑ Manhole diameter ❑ Catch Basin feet x feet Number and Height of Cartridges: Count each ❑ 12" ❑ 18" ❑ 24" ❑ 30" Media Type: ❑ ZPC ❑ Perlde ❑ Other Condition of Internal Components Notes ❑ Good ❑ Damaged ❑ Missing Inlet Pipe Blockage or Obstruction Notes: ❑Yes ❑No Floating Trash and Debris Notes ❑ Significant ❑ Not Significant Floating Oils Notes ❑ Significant ❑ Not Significant ❑ Spill Sediment Depth in Inlet Chamber Notes ❑ Inches of Sediment: Sediment Depth in Treatment Chamber Notes — Inches of Sediment: Standings Water in Treatment Chamber Notes ❑ Inches of Standing Water: Maintenance Required ❑ Yes — Schedule Maintenance ❑ No — Inspect Again in Months RAM No. 17-038 Stormwater Site Plan Report r c a� E crs ;v c L 0 Q.

We live a t 9610 215th PL Sw. our Neighbors also object to this project affecting our street. This project would be very disruptive to the quiet small community on our cull de sac.

You are a party of record and will continue to receive applicable notices, including of the public hearing once it is scheduled. You'll receive a copy of the eventual staff report and a copy of the Hearing Examiner's decision on the preliminary plat. I apologize for the small size of the plan that was included — it's hard to fit as much info as you'd like into a particular mailing. I've attached the existing preliminary plans here (they may change somewhat by the time the project gets to the Hearing Examiner but this is the general idea) and all related info will be available at the Citizens Connect webpage here — search PLN20180034. By the looks of it, proposed Lot 6 would be adjacent to your lot. It would be considered to be a flag lot and so would have 7.5' setbacks from all property lines. Regarding the number of lots, a maximum of 10 is possible based on lot area. If you look at Sheet EC-01, there are three larger parcels being redeveloped but some previous discussions with the developer involved only Parcel 1 and maybe r 2. That might be where the 5 lot concept came from. Each newly created lot in this zone must be at least 8,000 sq. ft. just like all the lots in the neighborhood (yours is about 8,200 sq. ft. according to the County Assessor). E c0 Maximum height for all single family residential zones in Edmonds is 25 feet, which on level lots means two c stories. Each single family lot is required to provide a minimum of 2 off-street parking stalls. Typically these days that c means they are in enclosed garages. Driveways and adjacent streets would provide overflow parking as is common in the surrounding area. I would say that this developer (Select Homes) is the same one doing the new house at the end of Q. your block at 96t" — that's probably similar to the type of house you'd see with this project. �' c0 I hope this helps. If you have any additional questions, please let me know.

Pam Rabe From: Pam Rabe <pam_rabe@hotmail.com> Sent: Monday, June 25, 2018 6:31 PM To: michael.clugston@edmonds.gov Subject: Permit: PLN20180034 Dear Mr. Clugston, My name is Pam Rabe and my property at 9708 214th PI SW backs up to the proposed 10 house development by Select Homes, Inc. The main reason for this email is to express my concern about maintaining the vegetation on my property when the property in question is developed. I have five trees on the property line that back up to the proposed development area. The trees provide beauty, shade, higher property value and are good for the environment. I have been a responsible tree owner and in the 13 years I have owned my home I've had a certified arborist inspect my property every few years. At their advice, I've had several trees taken down due to the loss of integrity of the tree which could result in safety issues. Over the years I regularly have the trees pruned and dead branches removed. I aim to be a good neighbor and do the right thing. That being said, I would like some assurance that my trees will not be harmed. One in particular is right up against the property line and no doubt some of the roots extend into the proposed development area. I understand that Washington State law allows neighbors to trim trees that extend onto their property but that cutting roots or doing anything that could harm the tree is not allowed. I am hoping this won't be a problem but from the plans sent out by the City of Edmonds, I can't tell if a house will be built right up against the property line or a little further back .... which would seemingly then not be an issue if it were some feet back from the property line. Also, after the property was sold last year, I received a flyer from Windermere Real Estate saying that five new houses were being built on the property. Now I see that the developers plan to build 10 new houses. In my humble opinion, five houses seems reasonable (even 6 )but 10 seems completely out of scale for the neighborhood. I have been out of town for work and haven't had the time to go the edmonds.gov website to view the development application so I don't know if these homes will be two story or three story. Also, what plans are in place to mitigate parking once the homes are built? Where will visitors to these homes park? One can't park on 96th St. so one imagines visitors will have to park on 214th, 216th or 98th. r c as E c 0 Q. a� M 0 0 0 0 N z J a r a+ x w c as E a Attachment 11 - PLN20180034 Packet Pg. 153 2.1.a Thank you for your time.

An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instructions for Applicants: �+ This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. L a You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if M a question does not apply to your proposal, write "do not know" or does not apply". Complete answers to the questions now may N avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if N you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of a� E land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you um submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. c R Use of checklist for nonproject proposals: o For nonproject proposals complete this checklist and the supplemental sheet for nonproject actions (Part D). the lead agency may W exclude any question for the environmental elements (Part 13) which they determine do not contribute meaningfully to the analysis of the proposed nonproject actions, the references in the checklist to the words "project," "applicant," and "property or site" should be N read as "proposer," and "affected geographic area," respectively.

It is assumed that the fire hydrant is located within existing public right-of-way or has a prescriptive easement for its location. Stormwater Engineer Review: JoAnne Zulauf, June 13, 2018: 1. It does not appear that the referenced site specific soils report was included with submittal; please include with next round. Response: Site specific soils report added to stormwater report (see Section D.). 2. It is not clear how the 981h Ave W frontage improvements are to be collected and routed to the detention system; a. Update plan as needed to show how the frontage runoff will be collected and routed, OR b. Update report as needed to identify areas which are to bypass the detention facility and use a combined point of compliance analysis to assess project impacts. Response: A catch basin along 981h has been added to collect frontage improvements; the system_ adds additional "run on" area which is accounted for in the updated stormwater calculations. See t revised plans and stormwater report. x w r 3. It is unclear that the flow control standard is achieved at the project discharge point; the project discharge point is downstream of the pump and will therefore E be impacted by the pump operation.

The detention system and pump shall be privately owned and maintain; update plans and report to reflect private maintenance requirement. Response: Easement callouts have been revised to as "private" and maintenance summary in stormwater report identifies the maintenance for the detention system and pumps are private (see page F-1). 5. It is unclear if adequate room has been left for required freeboard and/or sediment storage as the 10' vault was modelled with a 9.8' riser. Ensure design elevations are adequate when revising plans and report. Response: Vault callout and sizing has been increased to 12 ft to accommodate the stormwater detention, see revised sheet UT-1 and updated stormwater report. 6. It appears that the vault configuration will require an access road which is not currently noted as a project impervious surface or mitigated for; include access road in mitigation surfaces (non-PGIS). Response: Vault access impervious (1,800 sf) has been added to the storm system design and total proposed site impervious, see page C-1 of updated stormwater report. 7. Update report downstream analysis to note apparent backwatered inlet pipe at the proposed existing CB connection point and address impacts (if any) of adding additional runoff to this system. Response: The downstream stormwater system does have minor 'jumps' through the catch basins downstream of the project. These 'jumps" (invert pipe out is above invert pipe in) are between 0.1' and 0.2' and minor compared to the overall system fall between catch basins that range between 1 ft to 2 ft (thus the upstream basins will not be backwatered by the downstream 'jumps"). Acknowledgement of these 'jumps" have been added to the offsite downstream evaluation in the stormwater report (p. C-3). Prior Construction Approval: The following comments were noted by the reviewer as issues that will likely require revision prior to construction approval, but do not necessarily required attention prior to feasibility approval. A. If engineering approves curb revisions to maintain use of existing CBs on 98th; make sure to address the sump condition created at each CB as a result (ie. account for debris/leaf build up). B. It appears that the rim elevations of CB #2 & CB #3 to not match topo and may need additional attention. Response: Catch basin rims have been updated and thru curb inlets have been added to existing catch basins along 98th; these items will also be included on final construction plan set.

The information provided indicates general engineering feasibility. The project -specific design, including final utility system design and location, as well as Title 18 Edmonds Community Development Code compliance, will be reviewed during the civil construction phase of this project. Preliminary approval shall not be interpreted to mean approval of the improvements as shown on the preliminary plans. Edmonds Community Development Code Chapter 18.80 establishes right-of-way and pavement widths for public and private streets. This project proposes to add access to 6 lots to 215t" PI SW, increasing the total lots accessed off 215t" PI SW to 11 lots. ECDC 18.80.010 Street Standards states that any street with access to over 10 lots shall construct a cul-de-sac as a dead end for the street. Therefore the subject development will be required to construct a cul-de-sac at the end of 215t" PI SW dedicated as public right of way to the City of Edmonds. This project proposes an eight foot easement from the back of curb which shall be provided to the City of Edmonds for public sidewalk, water and sewer utility to be constructed as part of the development. Edmonds Community Development Code (ECDC) Chapter 18.90 regulates the construction of sidewalks that could prevent the implementation of the comprehensive sidewalk plan. x w • Sidewalk is proposed as required in City of Edmonds standards for the construction of c a cul-de-sac along the lot frontage on 215t" PI W. E a City of Edmonds Attachment 16 - PLN20180034 Packet Pg. 186 2.1.a • In addition, this project proposes to add access to three lots on 98th Ave W. 981h Ave W. street right-of-way is classified as a local street dead ending to the north and per City Code, sidewalks are only required on one side of the street. Sidewalks have already been established on the west side of 98th Ave W and on the east side of 98th Ave W, both of which are not adjacent to the subject development. Please find attached the Engineering Requirements for the subject development. The applicant will be required to satisfy these requirements as a condition of plat approval. Subsequent to obtaining a preliminary plat determination of approval from the Planning Division, the applicant will be required to submit revised civil construction plans addressing all plat conditions. Plans are to be submitted to the Engineering Division. A civil plan review fee is to be paid at the time of submittal. At this time, the review fee is $4265.
