The existing conditions of SE 172nd Street on the south border of the proposed development should also be noted. The description on the Notice states that a driveway will be located at the west property line and connecting with SE l 72"d Sl A commercial driveway located next to our single-family residence to the west will have a negative impact on our property in terms of noise, pollution, and lowered property value. Additionally, a traffic study should be required to determine the impact the driveway will have on the added traffic to SE 172 St. The existing sidewalk and curbing on the south side of SE 172nd, west of I 08th SE and fronting the daycare center, are located in the center of the street right of way. The placement of these obstructions to traffic occurred in 1990 when the area was unincorporated King County and SE 172nd was very lightly used. It was, at the time, not an issue for County inspectors. Now that the area has been annexed and the City of Renton is transforming the area to high density from rural, the obstructions are a traffic and pedestrian safety issue. The parking curb on the south side of SE 172nd at the intersection with Benson Rd. extending to the western boundary of the proposed development is located twenty-seven feet from the property marker on the north side of SE l 72"d. If development of the required planting strip, sidewalks and curbs are placed along the north side prior to relocating the sidewalks on the south side, the width of SE 172nd would be reduced to thirteen feet, with no available parking. This is far from the minimum requirements for a mixed-use commercial road as has been designated by the City of Renton since the area was annexed. Since the City's reclassification of SE 172nd to a commercial-mixed use road from a residential street, no improvements have been made. It is stiH in the condition of a rural county road with high-density housing and commercial use being developed around it. It is being used by these developments as a short cut or way around the other clogged streets in the area. The City of Renton has shown disregard and negligence for the safety and well being of the families living in this older single family neighborhood. It seems, to many residents, that it is purposeful disregard. This was evidenced by the many thoughtful and concerned comments from residents in opposition to the placement of driveways to the Avana Ridge apartments onto SE 172nd. The City successfully argued on behalf of the non-resident developer to force traffic from the 74-unit apartment complex through the narrow roads with no streetlights or sidewalks, and against the concerns of the residents of the Renton neighborhood.

"Chip"Vincent, Administrator Renton Special Care Community/ LUA17-000023, CU-H, SA-A, ECF Dear Mr. Carl, The Planning Division of the City of Renton accepted the above master application for review on February 2, 2017. During our review, staff has determined that additional information is necessary in order to proceed further. The following information will need to be submitted before May 29, 2017 so that we may continue the review of the above subject application: • Please provide 5 full sized copies, 1 reduced copy (8 Y," x 11"), and an electronic copy of a revised site plan, landscape plan, generalized utility plan, grading plan, and preliminary drainage plan. The revised plans shall address the following comments: 1. The Proposed development fronts SE 172nd Street to the South. SE 172nd Street is a commercial mixed use and industrial access street. Existing right-of-way (ROW) width is approximately 60 feet. To meet the City's complete street standards for commercial missed use and industrial access streets, minimum ROW is 69 feet. Dedication of 4.5 feet of ROW fronting the site will be required. Half-street frontage improvements are required to be provided on the side of the street fronting the development. Frontage improvements would include an 8-foot parking lane, a 0.5 foot wide curb and gutter, an 8-foot wide landscaped planter, a 6-foot wide sidewalk, street lighting, and storm water improvements. a. The proposed frontage improvements along SE 172nd Street shown on the civil plans submitted by the applicant does not provide the LUA! 7-000023 Page 1 Community & Economic Development Department C.E."Chip"Vincent, Administrator minimum required pavement width of 20-feet for emergency vehicle access. Applicant shall provide a minimum of 26-feet of paved roadway to provide 20-feet for emergency vehicle access as well as to maintain the existing parking along the frontage of the property to the south of the development. 2. ADA access ramps shall be installed at all street crossings. Ramps shall be shown at each intersection. Ramps shall be oriented to provide direct pedestrian crossings. a.

All applications requiring environmental review will be presented to the City's Environmental Review Committee. The Environmental Review Committee is comprised of the Administrator of Public Works, the Administrator of Community and Economic Development, the Administrator of Community Services, and the Fire Chief. The Committee is responsible for determining whether the proposal will result in significant adverse environmental impacts. To do this, the committee will consider such issues as environmental health hazards, wetlands, groundwater, energy and natural resources and will then issue its decision (Environmental Threshold Determination). The Environmental Review Committee will either issue a: • Determination of Non-Significance (DNS)-Make a determination the proposal will have no significant negative environmental impacts, or • Mitigated Determination of Non-Significance (DNS-M)-Make a determination the proposal, if modified, would have no significant negative environmental impacts, or • Determination of Significance (DS)-Make a determination the proposal will have significant adverse environmental impacts and require the applicant to submit an Environmental Impact Statement (EIS) prepared by a qualified consultant. Once the Environmental Review Committee has issued its Environmental Threshold Determination (provided an EIS is not required), a public notice of the Determination is printed in the Renton Reporter and three notices are posted at or near the site. A 14-day appeal period commences following the publication date. At the discretion of the City, a separate and additional 15-day comment period may be added prior to the 14-day appeal period. In addition to issuing the Environmental Determination, the Environmental Review Committee is also charged with determining whether a public hearing should be required for those Site Plan proposals not automatically triggering a public hearing. The Environmental Review Committee will consider the departmental and public comments in determining whether or not a hearing should be required. This determination may be appealed within 14 days to the Hearing Examiner pursuant to Renton Municipal Code, Section 4-8-110. Projects exceeding the size limits listed in the Renton Municipal Code, Section 4- 9-20003 and projects abutting or <1cross the street from residential zones MUST have a public hearing. No variance from this requirement is possible. The remainder of the review process differs depending on whether a public hearing is required. Administrative Site Plan Review: A public hearing is not required. The Planning Division reviews the proposal for compliance with the requirements of RMC 4-9-200E, F in conjunction with the Environmental Review Committee decision and any staff or public comments prior to making a decision. The decision to approve, conditionally approve, or deny the proposal will be mailed to all persons listed on the Master Application and all parties of record. -11 - H:\CED\Data\Forms-Templates\Self-Help Handouts\Planning\sa.doc 03/12 Applicants may apply for building and construction permits concurrently with their request for a land r;:--=·\ use application. However, the applicant should be aware any conditions of land use permit approval may create a need for revisions to other permit applications whereby additional fees may be charged. Refunds of building permit charges are not available. If no appeals or reconsideration requests are filed within 14 days of the effective date of the decision to approve the application, the applicant may obtain building and construction permits. A construction permit for the installation of on-site and off-site utilities will be issued upon the review and approval of civil engineering drawings by the Division's Public Works Section and receipt of all applicable development and permit fees. A building permit will be issued upon the Building Section's approval of building plans and receipt of all applicable fees. ! DEFERRAL OF IMPROVEMENTS: _If a developer wishes to defer certain on-site or off-site improvements {i.e. landscaping, curbs and sidewalks), written application with full and complete engineering drawings ' must be submitted to the Planning Division. The application should explain the reasons why such delay is necessary. If approval is granted, security in the form of an irrevocable letter of credit, set-aside fund, assignment of funds, certified check or other type of security acceptable to the City shall be furnished to the City in an amount equal to a minimum of 150% of the estimated cost of the required improvements. EXPIRATION AND EXTENSIONS: Once an application has been approved, the applicant has two years to comply with all conditions of approval and to apply for any necessary permits before the approval becomes null and void. The approval body that approved the original application may grant a single two- r·'\ year extension. The approval body may require a public hearing for such extension. -13 -03/12 H:\CED\Data\Forms-Templates\Self-Help Handouts\Planning\sa.doc Kevin Carl ~ rom: Sent: To: Cc: Subject: Clark Close <CC1ose@Rentonwa.gov> Thursday, December 15, 2016 10:20 AM 'Daniel Westley' Kevin Carl; Jill Ding RE: Not Applicable Submittal Items -Renton Special Care Community PRE16-000115 Categories: Red Category Dan, Please see answers below.

In addition to the residential cottages the campus will also include a central Administrative cottage. This cottage program contains spaces for the administrative office suite and reception area, supporting a general manager, licensed nurse, marketer, activities director, The Administrative Cottage also houses our central commercial kitchen with a pantry and commercial laundry room. This area includes space for the cook's office, staff lockers, toilet room, dry and cold storage and scullery. The operation of the community provides all resident meal that are prepared by the chef in the commercial kitchen and delivered using hot box carts to each of the residential cottages. All soiled dishes are returned to the Commercial kitchens scullery for cleaning. 21Page MAGNET design. wevelopment 1631 15th Avenue W, Suite #21 I Seattle, WA 98119 206/778-4726 I 115116 The community's central laundry facility provides for the washing of all the residents bedding, towels and day to day clothing and is managed by facility staff. Each of the resident cottages also have a stacked pair of residential grade front load washer dryers. These are required by WAC regulations per our DSHS licensing and are intended to be used only by a resident for their family caregiver for their own personnel laundry needs. It is our experience, operating four other similar communities that this amenity is very rarely used since the facility provided laundry service is significantly more convenient. The four-building campus are connected by as 7'-0" cedar stockade fence with controlled entry gates, which contain a secure landscaped central courtyard which is freely accessed by community resident, staff and visitors alike. The courtyard provides outdoor patios, covered seating movable tables and chairs, art and a rich assortment of nontoxic trees and fiowering plants accessible by walkway paths. The goal of the overall facility design is to create a "family-like" living community where individual residents share the common areas of the campus while still maintaining their own personal space and privacy. The projected staff is anticipated to employ up to 27 full time equivalents (FTE's) working in three shifts with a maximum staff of 12 at any given time. A typical resident is anticipated to be between 70 and 85 years old, with a female to male ratio of about 60:40 with slight fiuctuations in this ratio over time. The typical length of stay is approximately one year. The resident's family usually lives within the general area 75% of the time. None of our resident has or operates a motor vehicle and they do not utilize public transit or off site community facilities such as libraries or parks. In addition to the primary functions of providing housing, meals and laundry services the facility provides the residents assistance with activities for daily living (ADLs). AOL help is specific to each resident and determined through a care plan which is designed by the nurse and administered by the CNAs on a scheduled basis. This care covers such things as help with dressing, bathing, and medication management but does not include functions usually administered in skill nursing facilities such as intravenous injections or other more intensive medical treatments. All Food Service for the campus is to be coordinated, prepared plated and delivered to the residential cottages via heated food cart. Once meals are completed in each cottages plates, utensils and glassware used for the meal are bused back to the commercial kitchen and delivered to the scullery for proper washing. Each cottage has as part of the day room an auxiliary kitchen which is provided to give the space a home like feel. But this kitchenette also includes a full-size refrigerator and micro wave oven. This appliance is not intended for the preparation of the resident's daily meals but rather as support to rewarming meals, making coffee/tea and light pre-prepared snacks. The facility will be licensed by the State of Washington through the Department of Social and Health Services (DSHS) as a boarding home licensure. 31Page MAGNET design,uevelopment 1631 15th Avenue W, Suite #21 I Seattle, WA 981 19 206/778-4 726 SITE LAYOUT, PARKING AND ACCESS 1115/16 The total built space for the cottage campus is approximately 17,725 gross square feet. Total site area is 66,000 square feet with a 45 percent Lot coverage. Approximately 12,000 square feet of landscaped courtyard is provided. A 7'-0" tall security fence is provided around the cottages and the court yard to assure safety for residents while allowing for emergency access. Renton Design Development Standards require one parking stall per 4 beds and one stall per employee (60 beds/4= 15 + IO for employees for a total of 25 required stalls. It is proposed to provide 21-24 parking stalls including 2 handicapped stalls ( I HC van stall). A drop off area is located adjacent to the main facility entry. Edit to reflect reduction Circulation internal to the project is provided by paved sidewalks along the parking lot and within the landscaped courtyard. A single vehicle entry egress access is proposed from I 08th Ave SE and located at the east side of the parking area. A secondary access driveway is available from the south side of the site off SE 172°' Street. The purpose of this access drive is primarily as a service drive for emergency vehicles, deliveries to the kitchen/laundry room, mail and packages for the administration office and for visitors who arrive from the SE 172°' Street corridor and trash removal.

The project is to serve as a convalescent center which automatically triggers the conditional use review. We have crafted our campus scale and aesthetic approach specifically to fit harmoniously within the surrounding residential context. Further, by keeping the design of the residential cottages as single level structures keeps the overall scale consistent with our neighbors while forming a secure interior courtyard that provide a safe and private indoor/outdoor living experience for our residents. The site is further enhanced by providing generous landscaping to restore the site and allows the project to knit itself back into the overall fabric of the neighboring lots. • Appropriate Location: The proposed location shall not result in the detrimental overconcentration of a particular use within the City or within the immediate area of the proposed use. The proposed location shall be suited for the proposed use. -Prior to selecting and purchasing the project site, we commissioned a market analysis by Wright Mature Marketing Inc. to determine the specific market needs and to identify the existing supply of convalescent center housing in the Renton area. This study determined that there is a sufficient need existing in the City of Renton and a current shortage of existing supply in the Renton highlands areas. The 60-bed resident capacity our project is based on this analysis and is targeted to service approximately 65% of the outstanding need. • Effect on Adjacent Properties: The proposed use at the proposed location shall not result in substantial or undue adverse effects on adjacent property. -Per our proposal, the overall site shall be generously landscaped with a wide variety of native plans, flowering plants, shrubs and trees to further soften the building presents towards the street frontage and our adjacent neighbors. The plant and tree pallet is also design to foster bird and other ground animal's habitat. • Compatibility: The proposed use shall be compatible with the scale and character of the neighborhood. -The Renton Special Care Community is scaled to integrate harmoniously within a single family and town home multifamily neighborhood surrounding our site. The 4 cottages campus that define the community consists of single level wood framed structures, the pallet of exterior building materials are constant with those used on the newly constructed Field Brook MAGNET design+devel ent 163115th Avenue W, Suite #211 Seattle, WA 98119 1/18/17 Commons town home development across 108th Avenue SE. Due to the memory challenges our residents live with our community circulation and activities are focused inward with residents remaining confined within the residential building or in the secure courtyard area. Building colors will be contemporary and friendly to reflect an inviting residential feel vs a commercial character. • Parking: Adequate parking is, or will be made, available. -Our residents do not drive and we operate with a staff of approximately 12 FTE's at any specific time during a 24-hour period. We have typically provided 20-26 parking spaces in our existing facilities of similar size and have found that to be sufficient to meet the facilities staff, service and family visitation needs. • Traffic: The use shall ensure safe movement for vehicles and pedestrians and shall mitigate potential effects on the surrounding area. -As with all of our communities we prepare a parking analysis study to identify the possible impacts the project will have on the surrounding area. The projects low concentration of 150 average daily trips and estimated 12 average peak hour trip show that this project will have a minimal impact on the surrounding road network. • Noise, Light and Glare: Potential noise, light and glare impacts from the proposed use shall be evaluated and mitigated. -All the site lighting shall be shielded and downward facing to minimize or prevent off site trespass of glare or light. We provide a 6' cedar good neighbor fence along the north and west property lines we share with single family residences and the prescribed landscape buffer to minimize noise and visual disturbances on our neighbors. The secure courtyard will further shield light, noise and glare from moving beyond the core area of the project site. • Landscaping: Landscaping shall be provided in all areas not occupied by buildings, paving, or critical areas. Additional landscaping may be required to buffer adjacent properties from potentially adverse effects of the proposed use. -Our landscape architectural team is highly skilled at creating lively and interesting site restorations that promote bird and animal habitat, seasonal color and fragrance variations as well as interesting foliage changes. The setback buffers included in our site design shall ensure that any impacts to our neighboring site will be minimal. ~--------------------- MAGNET desig velopment 163 I 15th Avenue W, Suite #21 I Seattle, WA 981 19 206/778-4726 Renton Special Care Community PROPOSED PROJECT ZONING & LANDUSE ZONING: SITE AREA: BUILDABLE AREA: LAND USE: NUMBER OF SLEEPING ROOMS: NUMBER OF RESIDENTS: NUMBER PARKING STALLS: Rl4 65,761 SF (1.51 ACRES) 51,761 SF (l.188ACREAS) Convalescent Home 4 -SINGLE STORY "COTTAGES" w/ SOG (3 Residential, I commercial) 43 60 24-26 (INCLUDING 2 HC) Renton Special Care Community 17033 1081h Avenue SE Renton, WA 98157 Site Plan & Conditional Use Submittal Materials JI ',, ' ' ~;'; t i: (;JfY (;.f R l:: Y() N FLA.N[\'if\'C L);\/ISION 9.

These trees were inventoried on October 21, 2016 to determine species, trunk size, canopy size, overall condition, and opportunity for preservation during construction of a multi-family special care community proposed for construction on the site. SITE DESCRIPTION The site consists of two adjoining parcels forming a slightly trapezoidal property measuring approximately 302'x 209' containing 65,754 s.f. (1.5 acres). The smaller northern parcel is developed with an existing single family residence and out building, and the larger southern parcel is undeveloped. The site is accessed by 108th Avenue SE along the east perimeter and SE 172nd Street along the south perimeter. Site topography varies from approx. elevation +412 in the northeast corner to +400 in the southwest corner creating a gradual and consistent slope to the southwest. No !ow points or ponding water were observed. The site includes 56 significant trees (minimum size 6" caliper or 8" caliper for cottonwood and alder) and the size and condition of each is described in the attached Tree Assessment Spreadsheet. Five of the significant trees qualify as landmark trees with trunk caliper of 30" or greater. In addition to the trees inventoried, the site is heavily vegetated with understory woody plants. The understory houses native species including vine maple saplings and beaked hazelnut, but is dominated by invasive species, primarily Himalayan blackberry with occasional English holly. PROPOSED PROJECT DESCRIPTION The proposed Renton Special Care Community consists of four multi-family residential buildings and associated parking, walks, gathering spaces and landscape that will be occupied by senior citizens and staff. As part of this project, road widening and public sidewalk installation is proposed along 103th Ave SE and SE 172nd Street on the east and south side of the site respectively. SITE ZONING The site is zoned R-14 (Residential) and is subject to Renton Municipal Code 4-4-130 Tree Retention and Land Clearing Regulations, and 4-4-070 Landscape and Tree Preservation requirements. METHODOLOGY Trees were inventoried by visual assessment performed by Greg Murphy and Callie Roberts of ELM Environments and documented in the attached "Tree Inventory Plan" and "Tree Assessment Report." A topographic survey prepared by others was used as a base for locating and identifying the trees, and tree caliper measurements in this report are based on the surveyed size except trees 2, 5, 11, 15, 191 42, 46, and 56 which did not appear on the survey and were field measured. OBSERVATIONS The dominant native tree species on site are Douglas fir (Pseudotsuga menziesii) and bigleaf maple (Acer macrophyllum) with three western red cedar (Thuja plicata), one black cottonwood (Populus trichocarpa), and five western hemlock (Tsuga heterophylla). Non-native species include six Austrian pine (Pinus nigra) and four apple trees (Malus pumila). The non-native species are located near the existing residence suggesting they were planted and not self-seeded. Most of the existing trees are clustered along the east edge of the property. Because of the varying tree density on site, most trees have asymmetrical and irregularly shaped canopies and several trees exhibit phototropic lean due to varying sunlight conditions. One Douglass fir was observed and noted to have been girdled by a cable or other attachments, but little other intentional damage to the trees was visible. CONSIDERATIONS Because the buildings and open spaces of the proposed special care facility will be inhabited by elderly and special needs individuals who may have vision, mobility or cognitive impairments, special consideration must be made for trees that could pose hazards in the form of branch or litter drop, trunk breakage, or tree uprooting. Construction excavation and grading will likely impact the shallow rooting Douglas fir (Pseudotsuga menziesii) and bigleaf maple (Acer macrophyllum) subjecting the trees to the potential of gradual decline and the risk of future structural failure. Therefore, trees that could potentially damage buildings or injure people have been identified in the assessment as "Hazard Trees." These hazard trees are excluded from tree salvage requirements. Due to the mobility concerns of the intended residents, the proposed project requires buildings and walks to be at matching elevations with no steps or ramps, requiring site grading modifications to provide the necessary building and walk adjacencies. Additionally, the pavement edges of 108th Ave SE and SE 172nd Street are being adjusted and new public walks are being added as part of city required right of way improvements which will necessitate grade adjustments beyond the right of way and into the site. The extent of these site grading modifications limits opportunities to preserve existing trees. The proposed project includes gradual slopes and new plants, so slope stability due to tree removal should not be a concern. RECOMMENDATIONS Recognizing the impacts that construction will have on the existing trees, and the risk of future branch drop or structural failure, it is recommended that trees be preserved only if they are small, ideally 6" to 8" caliper, located away from buildings or pedestrian areas, and in a location where root disturbance from construction excavation and grading will be minimized. Existing trees to remain should be protected by construction fence installed at the dripline radius per the City of Renton's standard construction detail. Since most of the site trees will likely be removed, a revegetation plan should be prepared meeting Renton's landscape requirements (RMC 7-7-070).

This onsite assessment and evaluation of critical areas (i.e. wetlands, streams, fish and wildlife habitat conservation areas) within and immediately adjacent to the project site was completed following the methods and procedures defined in the Corps of Engineers Wetland Delineation Manual (1987 Manual) with the 201 O Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (2010 Supplement); the guidance provided for the Washington State Wetlands Identification and Delineation Manual (Wash Manual); the State of Washington Department of Natural Resources (WDNR) Forest Practice Rules (WAC 222-16-030); and the City of Renton Chapter 3, Title 4.3.050 -Critical Areas Regulations. PROJECT SITE DESCRIPTION The project site was composed of two existing parcels of record located within an older residential area that was quickly becoming re-developed with the infilling of higher intensity new multi-family residential communities and commercial uses. Parcel 0087000285 was rectangular in shape, was 1.02-acres in size, was present vacant, and formed the southern portion of the project site. Parcel 0087000293 was rectangular in shape, was 0.48-acres in size, was dominated by an existing single family homesite, and formed the northern portion of the project site. The project site was bound on the north and west by existing homesites, on the south by SE 172nd Street with a commercial day-care south of SE 172"d Street, and on the east by 1081h Avenue SE with a multi-family residential community being constructed to the east of this public roadway. Directions to the Project Site: From SR 167 in the southern portion of the City of Renton exit onto SE Carr Road and continue easterly along SE Carr Road to the Benson Highway (SR515). Turn north onto the Benson Highway and a short distance to Benson Road South. Turn northeasterly onto Benson Road South and continue to the intersection of SE 172"d Street and Benson Road South. The project site located at the northwestern corner of this intersection. wetlands, streams, fisheries, wildlife -mitigation and permitting solutions P.O.

This mapping resource did not identify any wetlands or streams within or immediately adjacent to the project site. This mapping did identify a coal mine hazard area offsite to the south of the project site -similar to the King County Inventory Mapping. 2 15061 Washington State Natural Heritage Program The Washington State Natural Heritage Program was reviewed as a part of this assessment. This resource did not to identify any high quality, undisturbed wetland or a wetland that supports state threatened, endangered, or sensitive plant species within the Section/Township/Range of the project site. ONSITE EVALUATION Criteria for Critical Areas Identification The City of Renton defines "critical areas" to include aquifer recharge areas, habitat areas, frequently flooded areas, geologically hazardous areas, streams, and wetlands. The assessment documented within this report focused solely on habitat areas, streams, and wetlands. No specific assessment was undertaken by Habitat Technologies for potential aquifer recharge areas, ·frequently flooded areas, or geologically hazardous areas. Wetlands: The City of Renton defines "wetlands" as those areas designated in accordance with the Washington State Wetland Identification and Delineation Manual, as required by RCW 36.70A.175 (Ecology Publication #96-94). "Wetlands" are noted as those areas that are inundated or saturated, by ground or surface water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. However, with the adoption of the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (2010 Supplement) the Washington State Department of Ecology (WDOE) stated that to maintain consistency between the state and federal delineations of wetlands, Ecology has repealed WAC 173-22-080 (the state delineation manual) and replaced it with a revision of WAC 173-22-035 that states delineations should be done according to the currently approved federal manual and supplements. The changes became effective March 14, 2011 (https:l/fortress.wa.gov/ecy/publications/publications/ 1006002.pdf): Streams: A stream (aquatic area) is generally defined as a location where surface waters produce a defined channel or bed. A defined channel or bed is typically an area which demonstrates clear evidence of the passage of water and includes, but not limited to, bedrock channels, gravel beds, sand and silt beds, and defined channel swales. A stream need not contain water year-round. A stream typically does not include irrigation ditches, canals, storm or surface water run-off devices, or other artificial watercourses unless the constructed watercourse conveys a stream which naturally occurred prior to the construction of such watercourse. 3 15061 Fish and Wildlife Habitat Conservation Areas (FWHCAs): The City of Renton defines fish and wildlife habitat conservation areas as those habitats which meet any of the following criteria: • Habitats associated with the documented presence of non-salmonid species proposed or listed by the Federal government or State of Washington as endangered, threatened, candidate, sensitive, monitor, or priority; and/or • Category 1 wetlands. Onsite Assessment The onsite assessment of wetland, streams, and habitats was completed between mid- April and early May 2015. These assessments included periods of moderate to heavy seasonal rain events. These assessments followed the methodologies and procedures defined in the 1987 Manual with 2010 Supplement, guidance for the Wash Manual, and the City of Renton Chapter 3, Title 4.3.050 -Critical Areas Regulations. The project site had been modified by prior and ongoing onsite and offsite land use actions. These actions had included the development of single family homesites, the development of offsite multi-family residential and commercial land uses, and the development of public roadways and utilities. Field data work sheets are provided in Appendix A. • Plant Communities ONSITE: The plant communities throughout the project site had been modified by prior land use actions. The plant community within the northern parcel was dominated by a single family homesite. This plant community included a variety of retained native trees and shrubs, together with a variety of ornamental species and managed lawn. areas. This plant community was identified as non-hydrophytic in character (i.e. typical of non- wetlands). The plant community within the southern portion of the project site has also been modified by prior land use actions. However, this plant community had become re- established following there prior actions and included a variety of retained mature reproduction trees and often dense thickets of shrubs. Species observed included red alder (A/nus rubra), big leaf maple (Acer macrophyllum), Douglas fir (Pseudotsuga menziesi1), black cottonwood (Populus trichocarpa), hawthorne (Crataegus spp.), Himalayan blackberry (Rubus procera), evergreen blackberry (Rubus /aciniatus), Scots broom (Cytisus scoparius), hazelnut (Cory/us comuta), vine maple (Acer circinatum), Oceanspray (Ho/odiscus discolor), snowberry (Symphoricarpus a/bus), Douglas spiraea (Spiraea doug/asi1), rose (Rosa spp.), ivy (Hedera spp.), knotweed (Po/ygonum cuspidatum), sword fern (Polystichum munitum), bracken fern (Pteridium aqui/ium), bedstraw (Galium aparine), and false lily of the valh,y (Maianthemum dilatatum). This 4 15061 plant community was identified as non-hydrophytic in character (i.e. typical of non- wetlands). A roadside ditch was identified along the southern edge of the project site -associated with SE 172nd Street. The plant community within this ditch was regularly mowed as a part of street maintenance actions and included Douglas spiraea, rose, Himalayan blackberry, evergreen blackberry, velvetgrass (Ho/cus /anatus), bluegrass (Poa spp.), fescue (Festuca spp.), bentgrass (Agrostis spp.), reed canarygrass (Pha!aris arundinacea), bracken fern, Canadian thistle (Cirsium atvensis), cats ear (Hypochaeris g/abra), and nettle (Urtica dioica). OFFSITE: The offsite plant communities to the west and north were dominated by existing single family homesite. The plant community offsite to the northwest exhibited similar characteristics to the southern portion of the project site. • Soil Characteristics As identified at representative sample plots the soil throughout the project site exhibited characteristics typically associated with moderately to moderately well drained soil. The majority of the surface soil also exhibited characteristics typically associated with prior grading, the placement of imported fill materials, and the mixing of assorted debris. The soil in the southern portion of the project site exhibited a gravelly sandy loam texture and a surface soil coloration of dark brown (1 OYR 3/2) to a depth of approximately five (5) inches. The subsoil to a depth of eighteen inches exhibited a brown coloration (10YR 3/3). The soil did not exhibit prominent redoximorphic features or any other field indicators of hydric soil. The soil within the roadside ditch along the southern boundary of the project site had been modified by prior land use actions. This soil also included a variety of intermixed debris. • Hydrology Patterns The project site appeared to drain well to moderately well and did not exhibit field indicators of wetland hydrology. The project site was generally flat as a result of prior grading with a slight slope from east to west. • Wildlife Observations As a result of onsite and offsite urbanization the project site provided limited habitats for wildlife species. The majority of these species are commonly associated with manipulated and modified environments common to urban areas. Species observed onsite or that would reasonably utilize the habitats provided by the project site included American crow (Cotvus brachynchos), Northern flicker (Colaptes auratus), bushtit (Psaltriparus minimus), house finch (Carpodacus mexicanus), black capped chickadee (Parus atricapil/us), dark eyed junco (Junco hyema/is), violet green swallow 5 15061 (Tachycineta tha//assina}, song sparrow (Melospiza melodia}, purple finch (Carpodacus purpureus), starling (Sturnus vulgaris}, house mouse (Mus musculus), deer mouse (Peromyscus maniculatus), vole (Microtus spp.), opossum (Didelphis virginianus), stripped skunk (Mephitis mephitis}, eastern gray squirrel (Sciurus carolinensis), Norway rat (Rattus norvegicus), and coyote (Canis /atrans). The project site did not provide suitable spawning habitats for amphibians and did not provide habitats for fish species. State Priority Species: Priority species are defined by WDFW to require protective measures for their survival due to their population status, sensitivity to habitat alteration, and/or recreational, commercial, or tribal importance. Game Species: "Game species" are regulated by the State of Washington through recreational hunting bag limits, harvest seasons, and harvest area restrictions. The project site was not identified to provide habitats for State Game species. State Candidate: State Candidate species are presently under review by the State of Washington Department of Fish and Wildlife (WDFW) for possible listing as endangered, threatened, or sensitive. The project site was not identified to provide habitats for State Candidate species. State Monitored: State Monitored species are native to Washington but require habitat that has limited availability, are indicators of environmental quality, require further assessment, have unresolved taxonomy, may be competing with other species of concern, or have significant popular appeal. The project site was not identified to provide habitats for State Monitored species. State Sensitive: State Sensitive species are native to Washington, are vulnerable to decline, and are likely to become endangered or threatened throughout a significant portion of its range without cooperative management or removal of threats. The project site was not identified to provide habitats for State Sensitive species. State Threatened: State Threatened species are species native to the state of Washington and are likely to become an endangered species within the foreseeable future throughout a significant portion of its range within the state without cooperative management or removal of threats. The project site was not identified, nor documented to provide, critical habitats for State Threatened species. State Endangered: State endangered species are species native to the state of Washington and are seriously threatened with extinction throughout all or a significant portion of its range within the state. The project site was not identified, nor documented to provide, critical habitats for State Endangered species. 6 15061 Federally Listed Species: The project site has not been documented to provide critical habitats for federally listed species. CRITICAL AREA ASSESSMENT FINDINGS The project site had been impacted by prior and onsite land use actions and was located within an older residential area that was quickly becoming re-developed with the infilling of higher intensity new multi-family residential communities and commercial uses. Onsite assessment did not identify any wetlands, streams, of fish and wildlife habitat conservation areas within or immediately adjacent to the project site.

This report includes information that the Washington Department of Fish and Wildlife (WDFW) maintains in a central computer database. It is not an attempt to provide you with an official agency response as to the impacts of your project on fish and wildlife. This infom,ation only documents the location of fish and wildlife resources to the best of our knowledge. It Is not a complete inventory and it Is important to note that fish and wildlife resources may occur in areas not currenUy known to WDFW biologists, or in areas for which comprehensive surveys have not been conducted. Site specific surveys are frequently necesssary to rule out the presence of priority resources. Locations of fish and wildlife resources are subject to vraition caused by disturbance, changes in season and weather, and other factors. WDFW does not recommend using reports more than six months old. 05/12/2015 4. 55 WDFW Test Map May 12, 2015 D PHS Report Clip A r ea • AS MAPPED Ii] TOWNSHIP • PT L"' ~ SECTION gj QTR -TWP 1:19,842 0 0.1 5 0.3 0.6 mi I I I I I I I I I I I I 1 ' I 0 0.275 0.55 1.1 km Source : Esrl Dl9taG b be, GeoEye, Earthstar Geogre phcs, CNES/Alrbus cs .

(PSI) is pleased to submit this addendum letter to PSl's geotechnical site evaluation letter entitled "Site Investigation and Analysis of Previous Geotechnical Report, Renton Special Care Community, 17033 -108th Avenue SE, Renton, Washington" dated November 2, 2016. This addendum letter summarizes the additional work accomplished and provides estimated infiltration rates for the potential infiltration system located along the northern and western edges of the site. PSI performed the requested services in general accordance with our revised proposal agreement dated September 29, 2016 and our change order issued on December 9, 2016. For site-specific information, other than that which is related to the infiltration testing conducted on December 19th and 20 1h, 2016, please refer to our November 2, 2016 letter report. Conclusions and recommendations presented in the original geotechnical evaluation letter remain valid unless superseded by this addendum letter. SITE CONDITIONS The site is mostly wooded with a single family home on the north side of the site. A filled in ground swimming pool is located in the backyard area along with a concrete pad and an old dilapidated shed. Our review of the provided topographic profile shows the site slopes down from the northeast to the southwest from an elevation of approximately EL 415 feet to EL 400 feet above the mean sea level, over a distance of approximately 350 feet. The highest elevations are along the northeastern portion of the site and the lowest in the southwestern portion of the site. Based on a review of the geology of the region utilizing the Washington Department of Natural Recourses Interactive Geologic Map, and our geotechnical investigation of the site, PSI observed that this area is underlain by glacial till. Glacial till generally consists of silts, sands and gravels that have been overridden by a continental glacier. Renton Special Care Community /nfiltrat1ot1 Testing 17033 -J08 11r Avenue, Renton, Washington PSI Project No 07121465 SUBSURFACE CONDITIONS Professional Service Industries, Inc. Engineering• Consulting • Testing January 6, 2017 Page 2 o/4 Subsurface explorations for the infiltration tests were conducted on December 19'", 2016 with 4 borings drilled with a limited access rig using hollow stem auger drilling techniques. These borings were designated as IT-1 through IT-4. Each borings was drilled to a depth ranging from 3 to 4 feet below existing ground surface (bgs). PSI collected samples of soil from the base on each infiltration test location. Each soil boring terminated in silty sand soils consistent with the previously observed glacial till soils noted in our previous report (see attached sieve data). The approximate locations of the soil borings and infiltration tests are shown on Figure 1. Logs of the subsurface explorations and laboratory testing results for this study are included in the attachments. FIELD INFILTRATION TESTING PSI performed four infiltration tests in this investigation. These infiltration tests were conducted at the maximum depths of the borings; (3 to 4 feet bgs), groundwater was not encountered at these locations. Based on readily available well logs listed with the Washington State Department of Ecology and our recent site investigation, groundwater is not anticipated within the upper 50 feet of the existing site grades, however, rainfall and other factors could lead to perched levels in the upper subsurface areas. Infiltration tests were conducted in each of these borings within the 6 inch inside diameter Polyvinyl Chloride (PVC) pipe. The pipe was placed in firm contact with undisturbed soil and backfilled with onsite soils around the perimeter. Approximately 2 inches of washed pea gravel was placed in the base of the pipe and loosely tamped into place prior to testing. PSI added water to each test location and noted that slow percolation rates were occurring. Approximately 6 inches of water was added into each tested pipe, above the pea gravel, with minor amount of water added periodically to maintain water levels in the borings. The borings were left over night to hydrate for at least 16 hours. The next day PSI observed that water still remained in each test pipe, but water was added to increase the water levels to approximately six inches in the test holes. Readings were collected over the next four hours until a stabilized rate was observed at each location for at least three consecutive readings. The measured Infiltration rates ranged from approximately 0.10 to 0.22 inches per hour. The infiltration rates listed in this report are measured field infiltration rates and do not have a factor of safety applied to them. Infiltration rates are indicative of the soils at the specific location, depth and time in which they were conducted. Variations of any of these factors may alter the observed infiltration rates. Infiltration rates measured during our field investigation are shown in Table 1 below.

F9eometry = width of the infiltration gallery relative to the depth of groundwater below the infiltration system calculated by: Feeometry = 4*0/W + 0.05, Where D = depth of groundwater below the infiltration system and W = width of the infiltration system. Based on measured water levels near the site being greater than 50 feet, PSI recommends using 50 feet for the depth to groundwater. F9eometry must be no less than 0.25 and no greater than 1.0. Determining the actual groundwater elevation at the site may improve the accuracy of maximum high annual groundwater elevation but will likely not significantly affect the design infiltration rate. Fp1ugging = plugging factor which varies depending on the subsurface soil type. For this site it will be taken to be 0.8, which is recommended for loamy sand (silty sand). Infiltration rates used in design of any infiltration gallery should be determined based on the above calculations. Based on the current information provided by LDC design criteria and rates are summarized in the table below.

Geotechnical Services Are Performed lor Specific Purposes, Persons, and Projects Geotechnical engineers structure their services to meet the specific needs of their ciients. 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 solely/or 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 ---not even you~ should apply tr,e 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 Engineering Report Is Based on A Unique Set or Project-Specific Factors Geotechnical engineers consider a number of unique, project-specific fac- tors when establishing the scope of a study. Typ;cal 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, • 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 exist:ng geotechnical engineering report include tl1ose 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 ownersr.ip. As a general rule, always inform your geotechnical engineer of project change5-ilven minor ones-,md request an assessment of !heir 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 pertormed. Do not rely on a geotechnicai engineer- ing repo!lwhose 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 Geotechnlcal Findings Are Professional Opinions Site exp:oration identifies subsurtace conditons only at those points where subsurtace 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 cuflditions throughout the site. Actual subsurface conditions may differ-sometimes significantly~ from those indicated in your report. Retaining the geotectmical 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 Notfinal Do not overre:y 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 subsurtace 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 ,n 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 never be redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separa#ng 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 sobsurtace conditions by limiting what they provide for bid preparation. To help prevent costly problems, give con- tractors the complete geotechnical engineering report, bu/preface it wi:h 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 inforrmtion they need or prefer. A prebid conference can also be valuable. Be sure contrac- tors have sufficient time to pertorm additional study. Only then might you ll€ 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 ResponsibUity 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 pertorm a geoenviron- mental study differ significantly from those used to pertorm a geotechnical study. For that reason, a gsotechnical 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 surtaces. To be effective, all such strategies should oe devised for the express purpose of mold prevention, integrated ,nto a com- prehensive plan, and executed witn 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 rnay l1ave been addressed as part of the geotechnical engineering study whose findings are conveyed irHtlis 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 be sufficient to prevent mold from growing in or on the structure involved.

IIGER06045.0M November 11, 2015 ES-3613 Mr. Stein Skattum P.O. Box 769 Renton, Washington 98057 Dear Mr. Skattum: Earth Solutions NW LLC • Gcotcchnical Engineering • Construction Monitoring • Environmental Sciences Earth Solutions NW, LLC (ESNW) is pleased to present this report titled "Geotechnical Engineering Study, Proposed Residential Subdivision, 17033 -1081h Avenue Southeast, Renton, Washington". In our opinion, the proposed residential development is feasible from a geotechnical standpoint. Our subsurface exploration indicates the site is primarily underlain by Vashon till. During our subsurface exploration completed on October 14, 2015, groundwater seepage was not encountered at the test pit locations; nonetheless, discrete, perched seepage zones should be anticipated during construction depending on the time of year grading activities take place. In our opinion, the proposed residential structures may be supported atop conventional continuous and spread footing foundations bearing on competent native soil, recompacted native soil, or new structural fill. In general, competent native soil suitable for support of new foundations will be encountered within the upper two to three feet of existing grades. Where loose or unsuitable soil conditions are exposed at foundation subgrade elevations, compaction of the soils to the specifications of structural fill, or overexcavation and replacement with a suitable structural fill material, will be necessary. Construction of the proposed stormwater detention vault is feasible from a geotechnical standpoint. We anticipate competent, dense to very dense, undisturbed Vashon till will be encountered within excavations at depth for the vault foundation subgrade elevation. Because the native soils are largely comprised of Vashon till, it is our opinion infiltration into native soils should be considered generally infeasible. Recommendations for foundation design, site preparation, drainage, preliminary stormwater detention vault design, and other pertinent development aspects are provided in this study. We appreciate the opportunity to be of service to you on this project. If you have questions regarding the content of this geotechnical engineering study, please call.

The purpose of this study was to provide geotechnical recommendations for currently proposed development plans. Our scope of services for completing this geotechnical engineering study included the following: • Completing subsurface test pits for purposes of characterizing site soils; • Completing laboratory testing of soil samples collected at the test pit locations; • Conducting engineering analyses, and; • Preparation of this report. The following documents and maps were reviewed as part of our report preparation: • Geologic Map of the Renton Quadrangle, King County, Washington, by D. R. Mullineaux, 1965. • Liquefaction Susceptibility of King County (Map 11-5), prepared by the King County Flood Control District, May 2010; • Site Plan, Sheet No. A1 .0, prepared by Mark Travers Architect, dated September 30, 2014, and; • Online Web Soil Survey (WSS) resource, provided by the Natural Resources Conservation Service under the United States Department of Agriculture. Project Description We understand the proposed development will include construction of 16 single-family residential lots, access and drive tracts, a stormwater detention vault (vault), and other associated improvements. Rockeries and/or retaining walls may be incorporated into final designs to accommodate grade transitions, where necessary. The vault is proposed for construction generally within the central site area, and we anticipate excavations to reach the vault foundation subgrade elevation will be on the order of 10 feet bgs. To the best of our knowledge, the site is not associated with any geotechnically relevant geologic hazards as defined by the City of Renton. Mr. Stein Skattum November 11, 2015 ES-3613 Page2 At the time of report submission, specific grading and building load plans were not available for review; however, based on our experience with similar developments, the proposed residential structures will likely be constructed at grade (following site mass grading) utilizing relatively lightly-loaded wood framing supported on conventional foundations. We anticipate the residential structures will incorporate slab-on-grade floors or crawl space construction at grade. We anticipate perimeter footing loads on the order of 1 to 2 kips per lineal foot (kif). Slab-on- grade loading is anticipated to be on the order of 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 final designs to confirm that our geotechnical recommendations have been incorporated into the plans. SITE CONDITIONS Surface The subject site is located northwest of the intersection between Southeast 172"d Street and 1081h Avenue Southeast in Renton, Washington. The site and the surrounding upland area are commonly referred to as Benson Hill. The approximate location of the property is illustrated on Plate 1 (Vicinity Map). The rectangular property is comprised of two adjoining tax parcels (King County Parcel Nos. 008700-0285 and -0293) totaling approximately 1.51 acres. The site is enveloped to the north and west by single-family residential homes, to the south by Southeast 172nd Street, and to the east by 1081h Avenue Northeast. A single-family residence and associated outbuildings currently occupy the site and will be removed in lieu of the proposed subdivision. The existing topography is relatively level across the central and northern areas of the site; grades descend approximately 5 to 1 O feet within the western and southern site areas to each respective property line. Existing vegetation is comprised primarily of dense tree, brush, and bramble cover across the majority of the southern two-thirds of the site. Subsurface An ESNW representative observed, logged, and sampled seven test pits, excavated at accessible locations within the proposed development area, on October 14, 2015 using a mini trackhoe and operator retained by our firm. The test pits were completed for purposes of assessing soil conditions, classifying site soils, and investigating the presence of groundwater below the existing ground surface (bgs). 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. Soil samples collected at the test pit locations were analyzed in accordance with both United States Department of Agriculture (USDA) and Unified Soil Classification System (USCS) methods and procedures. Earth Solutions NW, LLC Mr. Stein Skattum November 11, 2015 Topsoil and Fill ES-3613 Page 3 In general, topsoil was encountered within the upper 6 to 15 inches of existing grades at the test pit locations. The topsoil was characterized by dark brown color, the presence of fine organic material, and small root intrusions. Based on our field observations, we expect topsoil will be encountered within the upper 9 to 10 inches of existing grades. Fill was not explicitly encountered at the test pit locations during our fieldwork. We suspect fill will be encountered within proximity to existing structural improvements. If desired, ESNW should verify the suitability of existing fill deposits, where encountered, to be reused as structural fill. Native Soil Underlying topsoil, native soils at the test pit locations were comprised primarily of silty sand with gravel (USCS: SM), consistent with the typical makeup of Vashon till. It is noted sandstone deposits and fragments were encountered at TP-3 near a depth of about two to four feet bgs. In general, the upper two to four feet of the Vashon till was characterized as "weathered" and was encountered in a loose to medium dense state, while the Vashon till at depth was characterized as "unweathered" and was encountered in a dense state. The presence of iron oxide staining was also considered in our characterization of the upper Vashon till deposits as "weathered". Native soils were primarily encountered in a damp condition and extended to the maximum exploration depth of eight feet bgs. Geologic Setting The referenced geologic map resource identifies ground moraine deposits (Qgt), otherwise known as Vashon till, as underlying the site and surrounding areas. According to the geologic map resource, Vashon till is typically a compact, coherent, and unsorted mixture of sand, silt, clay, and gravel which is commonly referred to as "hardpan". The referenced WSS resource identifies Alderwood gravelly sandy loam (Map Unit Symbol: AgC) across the site and surrounding parcels. The Alderwood series was formed in hills and ridges. Based on our field observations, native soils underlying the subject site, specifically those likely to be encountered during construction, are consistent with ground moraine deposits (Vashon till) as described in this section. The deposits encountered on site are consistent with those areas across the majority of Benson Hill, which are also mapped to be underlain primarily by Vashon till. Based on our field observations, as well as the results of previous explorations on nearby properties, bedrock of the Renton formation is likely present at depth underlying the Vashon till. Earth Solutions NW, LLC Mr. Stein Skattum November 11, 2015 Groundwater ES-3613 Page4 During our subsurface exploration completed on October 14, 2015, groundwater seepage was not encountered at the test pit locations. Iron oxide staining was observed within the upper one to three feet of existing grades. In our opinion, discrete, perched groundwater seepage zones may be encountered during construction, particularly within excavations at depth for site utilities and the vault. 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 flow rates are higher during the wetter, winter months. DISCUSSION AND RECOMMENDATIONS General In our opinion, construction of the proposed residential development on the subject site is feasible from a geotechnical standpoint. The primary geotechnical considerations associated with the proposed development include foundation support, slab-on-grade subgrade support, the suitability of using on-site soils as structural fill, and construction of the vault. In our opinion, the proposed residential structures may be supported atop conventional continuous and spread footing foundations bearing on competent native soil, recompacted native soil, or new structural fill. In general, competent native soil suitable for support of new foundations will be encountered within the upper two to three feet of existing grades. Where loose or unsuitable soil conditions are exposed at foundation subgrade elevations, compaction of the soils to the specifications of structural fill, or overexcavation and replacement with a suitable structural fill material, will be necessary. Construction of the proposed stormwater detention vault is feasible from a geotechnical standpoint. We anticipate competent, dense to very dense, undisturbed Vashon till will be encountered within excavations at depth for the vault foundation subgrade elevation. Because the native soils are largely comprised of Vashon till, it is our opinion infiltration into native soils should be considered generally infeasible. This study has been prepared for the exclusive use of Mr. Stein Skattum and his 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 Preparation and Earthwork Initial site preparation activities will consist of installing temporary erosion control measures, establishing grading limits, removing existing structural improvements, and performing clearing and site stripping (as necessary). Subsequent earthwork activities will involve mass site grading and related infrastructure improvements. Earth Solutions NW, LLC Mr. Stein Skattum November 11, 2015 Temporary Erosion Control ES-3613 Page 5 Ingress and egress to the proposed development will be provided off both Southeast 172nd Street and 1081h Avenue Northeast. Prior to finished pavement installation, temporary construction entrances and drive lanes, consisting of at least 12 inches of quarry spalls, should be considered in order to minimize off-site soil tracking and to provide a stable access entrance surface. Geotextile fabric may also be considered underlying the quarry spalls for greater stability of the temporary construction entrance. Erosion control measures should consist of silt fencing placed around down gradient margins of the site. Soil stockpiles should be covered or otherwise protected to reduce soil erosion. Temporary approaches for controlling surface water runoff should be established prior to beginning earthwork activities. Additional Best Management Practices (BMPs), as specified by the project civil engineer and indicated on the plans, should be incorporated into construction activities. Stripping In general, topsoil was encountered within the upper 6 to 15 inches of existing grades at the test pit locations. For preliminary estimation purposes, it is our opinion an average topsoil stripping depth of 9 to 10 inches should be anticipated. ESNW should be retained to observe site stripping activities at the time of construction in order to assess the required degree of stripping. Over-stripping should be avoided as it is unnecessary and may result in increased project development costs. Topsoil and organic-rich soil is neither suitable for foundation support nor for use as structural fill. Topsoil and organic-rich soil may be used in non-structural areas if desired. In-situ Soils From a geotechnical standpoint, in general, our field observations indicate on-site soils likely to be encountered during construction will be suitable for use as structural fill, provided the soil moisture content is at (or slightly above) the optimum level at the time of placement and compaction. Site soils should be considered highly moisture sensitive, and successful use of on-site soils as structural fill will largely be dictated by the moisture content at the time of placement and compaction. Soil that is found to be dry at the time of installation will likely require moisture conditioning (typically achieved through the application of water) prior to soil compaction. Soil encountered during site excavations that is excessively over the optimum moisture content will likewise require moisture conditioning (typically achieved through soil aeration) prior to placement and compaction. It should be emphasized native material should never be placed and compacted dry of the optimum moisture content, especially in site utility trench applications. If the on-site soils cannot be successfully compacted, the use of an imported soil may be necessary. Earth Solutions 'MN, LLC Mr. Stein Skattum November 11, 2015 Imported Soils ES-3613 Page 6 Where 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 slightly above 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). Subgrade Preparation Foundation and slab subgrade surfaces constructed atop both native soils and/or compacted structural fill should exhibit firm and stable characteristics. Uniform compaction of the foundation and slab subgrade areas may be necessary to establish a consistent subgrade condition below the foundation and slab elements. ESNW should observe subgrade areas prior to placing formwork. Supplementary recommendations for subgrade improvement may be provided at the time of construction and would likely include further mechanical compaction or overexcavation and replacement with suitable structural fill. 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 at least 90 percent, based on the laboratory maximum dry density as determined by the Modified Proctor Method (ASTM D1557). Soil placed in the upper 12 inches of slab-on-grade, utility trench, and pavement areas should be compacted to a relative compaction of at least 95 percent. More stringent compaction specifications may be required for utility trench backfill zones depending on the responsible utility district or jurisdiction. Foundations In our opinion, the proposed residential structures may be supported atop conventional continuous and spread footing foundations bearing on competent native soil, recompacted native soil, or new structural fill. In general, competent native soil suitable for support of new foundations will be encountered within the upper two to three feet of existing grades. Where loose or unsuitable soil conditions are exposed at foundation subgrade elevations, compaction of the soils to the specifications of structural fill, or overexcavation and replacement with a suitable structural fill material, will be necessary. Provided foundations will be supported as described above, the following parameters may be used for design: • Allowable soil bearing capacity • Passive earth pressure • Coefficient of friction Earth Solutions NW, LLC 2,500 psf 350 pcf (equivalent fluid) 0.40 Mr. Stein Skattum November 11, 2015 ES-3613 Page 7 A one-third increase in the allowable soil bearing capacity may be assumed for short-term wind and seismic loading conditions. The above passive pressure and friction values include a minimum factor-of-safety of 1.5. With structural loading as expected, total settlement in the range of one inch, as well as differential settlement of approximately one-half inch, is anticipated. The majority of the settlements should occur during construction as dead loads are applied. Seismic Design The 2012 International Building Code recognizes the American Society of Civil Engineers (ASCE) for seismic site class definitions. In accordance with Table 20.3-1 of the ASCE Minimum Design Loads for Buildings and Other Structures manual, Site Class D should be used for design. The referenced liquefaction susceptibility map indicates the site and surrounding areas maintain very low liquefaction susceptibility. Liquefaction is a phenomenon where saturated or loose soils suddenly lose internal strength and behave as a fluid. This behavior is in response to increased pore water pressures resulting from an earthquake or other intense ground shaking. Based on our field observations, it is our opinion site susceptibility to liquefaction during a seismic event may be considered negligible. The relatively consistent densities of native soils at depth and the absence of a uniformly established, shallow groundwater table were the primary bases for this opinion. Slab-on-Grade Floors Slab-on-grade floors for the proposed residential structures should be supported on a firm and unyielding subgrade. Where feasible, native soil likely to be exposed at the slab-on-grade subgrade levels can be compacted in situ to the specifications of structural fill. Unstable or yielding areas of the subgrade should be recompacted, or overexcavated and replaced with suitable structural fill, prior to construction of the slab. Highly organic soils exposed at slab-on- grade subgrade elevations will likely require overexcavation and replacement with suitable structural fill. A capillary break consisting of at least four inches of 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 (percent passing the Number 200 sieve, based on the minus three-quarter inch fraction). In areas where slab moisture is undesirable, installation of a vapor barrier below the slab should be considered. If a vapor barrier is to be utilized, it should be a material specifically designed for use as a vapor barrier and should be installed in accordance with the specifications of the manufacturer. Retaining Walls Retaining walls must be designed to resist earth pressures and applicable surcharge loads. The following parameters may be used for design: Earth Solutions NW, LLC Mr. Stein Skattum November 11, 2015 • Active earth pressure (yielding condition) • At-rest earth pressure (restrained condition) • Traffic surcharge* (passenger vehicles) • Passive earth pressure • Coefficient of friction • Seismic surcharge • Where applicable " Where H equals the retained height (in feel) 35 pcf (equivalent fluid) 50 pcf ES-3613 Page 8 70 psf (rectangular distribution) 350 pcf (equivalent fluid) 0.40 6H psf** The above design parameters are based on a level backfill condition and level grade at the wall toe. Revised design values will be necessary if sloping grades are to be used above or below retaining walls. Additional surcharge loading from adjacent foundations, sloped backfill, or other relevant loads should be included in the retaining 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 12 inches of the wall backfill may consist of a less permeable soil, if desired. A perforated drain pipe should be placed along the base of the wall and connected to an approved discharge location. A typical retaining wall drainage detail is provided on Plate 3. If drainage is not provided, hydrostatic pressures should be included in the wall design. Drainage Although groundwater was not explicitly encountered at the test pit locations during our fieldwork, it is our opinion discrete, perched groundwater seepage zones should be anticipated within site excavations depending on the time of year grading operations take place, particularly within excavations at depth for site utilities and the vault. Temporary measures to control surface water runoff and groundwater during construction would likely involve interceptor trenches and sumps. ESNW should be consulted during preliminary grading to identify areas of seepage and to provide recommendations to reduce the potential for instability related to seepage effects. Finish grades must be designed to direct surface drain water away from structures and slopes. Water must not be allowed to pond adjacent to structures or slopes. In our opinion, foundation drains should be installed along building perimeter footings. A typical foundation drain detail is provided on Plate 4. Earth Solutions NW, LLC Mr. Stein Skattum November 11, 2015 Infiltration Feasibility ES-3613 Page 9 As indicated in the Subsurface section of this report, native soils encountered during our fieldwork were characterized primarily as Vashon till. Subsequent to USDA textural analyses, the Vashon till was further classified primarily as gravelly sandy loam. From a geotechnical standpoint, the Vashon till should not be considered an ideal geologic feature to accommodate infiltration, especially when encountered in a dense, compact state. In general, the Vashon till should not be considered feasible for infiltration purposes. It should be noted, however, Vashon till can likely accommodate construction of rain gardens (bioretention) and other limited- infiltration facilities. ESNW can provide further evaluation of, and recommendations for, stormwater flow control BMPs upon request. Preliminary Detention Vault Design Stormwater is proposed to be managed by a below-grade detention vault which is proposed for construction generally within the central portion of the site. Specific grading plans for the vault were not available for review at the time of report preparation; however, we anticipate grade cuts on the order of 10 feet will be necessary to achieve the vault foundation subgrade elevation. Based on our field observations, grade cuts for the vault are likely to expose dense to very dense, undisturbed Vashon till. The vault foundation should be supported on competent native soil or crushed rock placed atop competent native soil. The final vault design must incorporate adequate buffer space from property boundaries such that temporary excavations to construct the vault structure may be successfully completed. Perimeter drains should be installed around the vault and conveyed to an approved discharge point. Perched groundwater seepage should be anticipated within excavations for the vault. The following preliminary design parameters may be used for the vault: • Allowable soil bearing capacity (dense Vashon till) • Active earth pressure (unrestrained) • Active earth pressure (unrestrained, hydrostatic) • At-rest earth pressure (restrained) • At-rest earth pressure (restrained, hydrostatic) • Coefficient of friction • Passive earth pressure Earth Solutions NW, LLC 5,000 psf 35 pcf 80 pcf 50 pcf 95 pcf 0.40 350 pcf Mr. Stein Skattum November 11, 2015 ES-3613 Page 10 Retaining walls should be backfilled with free-draining material or suitable sheet drainage that extends along the height of the walls. The upper one foot of the wall backfill may consist of a less permeable soil, if desired. A perforated drain pipe should be placed along the base of the wall and connected to an approved discharge location. If the elevation of the vault bottom is such that gravity flow to an outlet is not possible, the portion of the vault below the drain should be designed to include hydrostatic pressure. ESNW should observe grading operations for the vault and subgrade conditions prior to concrete forming and pouring. If the soil conditions encountered during construction differ from those anticipated, supplementary recommendations may be provided. ESNW should be contacted to review final vault designs to confirm appropriate geotechnical parameters have been incorporated, as necessary. 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. Soils that exhibit a high compressive strength are allowed steeper temporary slope inclinations than are soils that exhibit a lower compressive strength. Based on the soil conditions encountered at the test pit locations, both loose and medium dense soils, as well as any area where groundwater seepage is exposed, are classified as Type C by OSHA and WISHA. Where encountered, fill should also be considered Type C soil. Temporary slopes over four feet in height in Type C soils must be sloped no steeper than one- and-one-half horizontal to one vertical (1.5H:1V). Dense, undisturbed native deposits encountered without the presence of groundwater may be classified as Type A by OSHA and WISHA. Temporary slopes over four feet in height in Type A soils must be sloped no steeper than 0.75H:1V. Type A soils that are fissured, subjected to vibrations from heavy traffic, or have been otherwise previously disturbed must be classified as Type B by OSHA and WISHA. Temporary slopes over four feet in height in Type B soils must be sloped no steeper than 1 H: 1 V. Steeper excavations for the vault may be permissible provided the excavations expose very dense, cemented Vashon till. ESNW can provide supplementary recommendations, including field observations of excavations for the vault, during the appropriate phase of construction. Where encountered, the presence of perched groundwater may cause caving of the temporary slopes due to hydrostatic pressure. ESNW should observe site excavations to confirm soil types and allowable slope inclinations. If the recommended temporary slope inclinations cannot be achieved, temporary shoring may be necessary to support excavations. Permanent slopes should be planted with vegetation to enhance stability and to minimize erosion and should maintain a gradient of 2H:1V or flatter. An ESNW representative should observe temporary and permanent slopes to confirm the slope inclinations are suitable for the exposed soil conditions. Supplementary recommendations with respect to excavations and slopes may be provided as conditions warrant. Earth Solutions NW, LLC Mr. Stein Skattum November 11, 2015 Pavement Sections ES-3613 Page 11 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 previously detailed in this report. II is possible that soft, wet, or otherwise unsuitable subgrade areas may still exist after base grading activities. Areas containing unsuitable or yielding subgrade conditions will require remedial measures, such as overexcavation and replacement with crushed rock or structural fill, prior to pavement. We anticipate new pavement sections will be subjected primarily to passenger vehicle traffic. For lightly loaded pavement areas subjected primarily to passenger vehicles, the following preliminary pavement sections may be considered: • A minimum of two inches of hot mix asphalt (HMA) placed over four inches of crushed rock base (CRB), or; • A minimum of two inches of HMA placed over three inches of asphalt treated base (ATB). The HMA, ATB and CRB materials should conform to WSDOT specifications. All soil base material should be compacted to a relative compaction of 95 percent, based on the laboratory maximum dry density as determined by ASTM 01557. Final pavement design parameters, including recommendations for heavy traffic areas or access roads, may be provided once final traffic loading has been determined. Road standards utilized by the City of Renton may supersede the recommendations provided in this report. Utility Support and Trench Backfill In our opinion, on-site soils will generally be suitable for support of utilities. Remedial measures may be necessary in some areas in order to provide support for utilities, such as overexcavation and replacement with structural fill, or placement of geotextile fabric. Groundwater seepage may be encountered within utility excavations and caving of trench walls may occur where groundwater is encountered. Depending on the time of year and conditions encountered, dewatering, as well as temporary trench shoring, may be necessary during utility excavation and installation. In general, on-site soils will likely be suitable for use as structural backfill throughout 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. Each section of the utility lines must be adequately supported in the bedding material. Utility trench backfill should be placed and compacted to the specifications of structural fill as previously detailed in this report, or to the applicable specifications of the City of Renton or other responsible jurisdiction or agency.

Soil and geologic materials, including groundwater are variable in nature. Geologic conditions vary vertically, laterally, and seasonally. The site soil is proven to be suitable to support foundations, landscaping, pavement, and other associated infrastructure in the area. However, the site soil also required careful planning and consideration with respect to design and construction. I/we understand, accept the risk and solely responsible of developing this property.

The feasibility of continued underground power (south of the subject property crossing SE 172°' St) was discussed and concluded to be economically infeasible for reasons listed below. Please reference the attached Existing and Proposed Power Plan, Figure 1.A, for evaluation purposes. As a disclaimer, I'm attempting to summarize the information presented to me in our meeting to the best of my ability. For additional and specific information, Brad can be contacted directly at: Brad Elkin, Assoc. Project Manager, Puget Sound Energy, 425-495-6489 Cell, Bradley.elkin@pse.com email. Continued underground power infeasibility (as discussed with PSE): 1. Infeasible routing -horizontal curve of 108th AVE SE and location of pole (east side of 108'h) doesn't allow efficient routing design and would require a ROW power vault "the size of a car" 2. Power Pole Anchorage -anchorage to the subject power pole would be in the middle of 108th Way SE in order to counter the opposing powerline tension forces 3. Power Outages -power outages would be required for this type of installation The attached underground power plan is the most sensible solution for providing underground power along the property frontage. Please review and provide additional commentary or concurrence as an email response. Thank you. Dan Daniel E.

I will need to know the extent of where to terminate the underground power on the south end of 1081h, as we are meeting with the EE and PSE onsite tomorrow afternoon. Do we need to cross SE 172'' with underground power? Just FYI, we pushed back tomorrow's scheduled submittal to next Thursday 1/19. Originally, I was planning on getting this feedback at our intake meeting tomorrow, but will need some input via phone call if ok. I'll try calling you to discuss. Thank you for the help!

Approximately 50,000 SF of impervious surface and roughly 21,000 SF of pervious surface is proposed onsite and within the Right-of-Way frontage. The proposed development proposes four convalescent buildings, access drive aisles, parking, associated utilities and ROW improvements on a 1.65 acre site. The subject property is located on parcels 0087000285 and 0087000293 at 17033 1081h Avenue SE, Renton, WA 98055. Access to the proposed project will be gained from the south and east via SE 172nd St and 1081h Ave SE respectively. The subject property is comprised of two parcels, one is currently developed with a vacant single-family residence, associated driveway and landscaped areas and the other parcel is undeveloped with moderate to dense vegetation. Site soils are dense to very dense Vashon Till, exhibiting low infiltration rates. Existing grades across the property are moderate across most the site, ranging from 2 to 25%, sloping mainly from the northeast to the southwest. Runoff from the site currently flows to the southwest and exits the subject property at the southwest corner of the site, entering the municipal storm drainage system located in SE 172nd ST. Downstream flows eventually outlet into the Black River, a tributary of the Duwamish River. A lot combination will be completed to combine the two parcels to one. Offsite frontage clearing activities will result in additional disturbed area impacts to the site. See Developed Hydrology Map, Figure 4.2 for a graphical depiction of the proposed development.

Per Chapter I of the Manual, the proposed development requires a Full Drainage Review, meeting all nine core requirements as well as all five special requirements, since there will be more than 2,000 square feet of new impervious surfaces and more than 7,000 sf of land disturbing activities. A summary of how each of the minimum requirements is met is described in this section. Core Requirement #1: Discharge at the Natural Location: The existing site runoff discharges the site along the southern and western property boundaries. All site runoff ends up in a roadside ditch located on the north end of SE 172nd ST. In the developed condition all runoff will be conveyed to the previously described natural discharge location. Core Requirement #2: Offsite Analysis: No discernable upstream run-off flows onto the subject property. Onsite runoff discharges as concentrated flow into a roadside ditch and culvert located in the southwest corner of the property. Downstream flows are conveyed in the westerly direction through a series of roadside ditch, culvert, storm pipe, catch basins and natural and engineered drainage swales. No signs of constrictions, capacity issues, erosion or sedimentation were noted along the downstream investigation. See Off site Analysis in Section 3 of this report. Core Requirement #3: Flow Control: Historic site conditions, assuming all forested, must be used for the predeveloped conditions. Flow control will be provided by a detention pipe facility located beneath the parking and access drive aisle along the western and northern property boundaries. See Flow Control/Water Quality Facility Analysis and Design, section 4 of this report for additional information. Technical Information Report 2-1 LDC Job No. 16-137 Core Requirement #4: Conveyance System: The new pipe system for this project will be sized to meet the 100-year peak flows. See Conveyance System Analysis and Design, section 5, for additional information regarding conveyance analysis and conveyance capacity. Core Requirement #5: Erosion and Sediment Control: See SWPPP Analysis and Design, Section 8 of this Report for the SWPPP BMP Elements. Core Requirement #6: Maintenance and Operations: The stormwater detention and water quality facilities will be maintained by the property owner. An emergency access easement will be granted to the City of Renton. See Operations and Maintenance in Section 10 of this report. Core Requirement #7: Financial Guarantees and Liability: Any required performance or assurance bonds will be posted with the City as required. Core Requirement #8: Water Quality: Based on the 2017 City of Renton SWDM, this project must meet the requirements of the Enhanced Basic Water Quality Treatment. The proposed enhanced treatment facility is a Filterra Bioretention Systems as approved by the City of Renton Public Works Department Blanket Adjustment dated June 26th, 2014. See Flow Control/Water Quality Analysis and Design in Section 4 of this report for additional information. Core Requirement #9: On-site BMPs: The 2017 City of Renton SWDM requires that all target surfaces must provide onsite BMPs to the maximum extent feasible to mitigate impacts of increased stormwater surface runoff per Large Lot BMP Requirements, section C.1.3.2. Permeable Pavement is the only feasible BMP applied to the site per section C.2.7, satisfying the onsite BMP requirements. Additionally all pervious surfaces will be protected in accordance with the soil amendment BMP detailed in Appendix C, Section C.2.1.3. See Flow Control/Water Quality Analysis and Design in Section 4 of this report for additional information. Technical Information Report 2-2 LDC Job No. 16-137 Special Requirement #1: Other Adopted Area-Specific Requirements: There are no Critical Drainage Areas, Master Drainage Plans, Basin Plans, Salmon Conservation Plans, Stormwater Compliance Plans, Lake Management Plans, Flood Hazard Reduction Plan Updates, or Shared Facility Drainage Plans within the vicinity of this project. Therefore, this requirement does not apply to the project. Special Requirement #2: Flood Hazard Area Delineation: Per the FEMA Flood Insurance Rate Map 53033C0979 F, the site is located in Zone C corresponding to an area outside of the 500-year flood plain. Therefore, there are no flood hazard areas (100-year floodplains, zero-rise flood fringe, zero-rise floodway, FEMA floodway, or channel migration zones) on or adjacent to this site. Therefore, this requirement does not apply to the project. Special Requirement #3: Flood Protection Facilities: There are no levees or revetments on or adjacent to this site. Therefore this requirement does not apply to the project. Special Requirement #4: Source Controls: Source controls are not required for this type of commercial site. Special Requirement #5: Oil Control: Only industrial sites are defined as high-use sites. This requirement does not apply to the proposed project. Technical Information Report 2-3 LDC Job No. 16-137 3.0 OFFSITE ANALYSIS Task 1. Study Area Definition and Maps King County LiDAR, survey, and 2012 aerial photography were the best topographical references available for the area containing the site. The limits of downstream analysis extended roughly 0.25 miles from the site's natural discharge location. Please reference Task 3 below for a detailed description of the downstream flow path (See Figure 3.0 Downstream Analysis Map). Task 2. Resource Review All of the resources below have been reviewed for existing and potential issues near the project site: • Adopted Basin Plans No Adopted Basin Plans were located that include the project site. • Drainage Basin This site is located within the Panther Creek drainage sub basin. The sub basin flows are tributary to the Black River and ultimately to the Duwamish River. • Floodplain / Floodway (FEMA) maps According to FEMA mapping this project is not within a floodplain. • Sensitive Areas Sensitive areas are not located on the site. • Drainage Complaints and Studies According to email correspondence with Ann Fowler, on 10/13/2017, there are not any drainage complaints of concern in or near the subject property's downstream flow path. • Road Drainage Problems No issues were identified near the proposed site. Technical Information Report 3-1 LDC Job No. 16-137 • Wetland Inventory Maps There are no wetland areas located on or downstream of the proposed subject property. This has been verified in the critical areas study as completed by others • Section 303d List of Polluted Waters The proposed subject property is not tributary to any 303d listed waters within 1/,i of a mile from the subject property. • Stormwater Compliance Plans Not applicable to the proposed project. Task 3. Field Inspection On Tuesday December 6th, 2016 upstream and downstream analyses were performed at the site. The following observations were verified during this visit. Please refer to Figure 3.0, Downstream Analysis Map, for reference locations. Upstream Analysis As observed on December 6th, 2016 site visit, there is no discernable upstream flow entering the proposed site. Downstream Analysis Runoff from the subject property discharges the site at the southwest property boundary and enters a 12" concrete driveway culvert located on the northern side of SE 172nd St. Flows continue westward through the roadside ditch and are redirected southerly, crossing SE 172nd St via a 12" concrete culvert, and are discharged into an open densely vegetated parcel to the south. Flows then enter an 18 inch concrete culvert, flow westerly, crossing State Route 515 Benson Dr. S, and are discharged into an engineered open channel located on a private parcel. Open channel flows are mitigated via 12"+ riprap and flows enter an 18" PVC pipe. Tightlined flows are conveyed westerly via 18" PVC pipe along 5 36th St., crossing the 1/,i mile downstream analysis extent boundary.

Technical Information Report 4-14 LDC Job No. 16-137 4.2 Water Quality Treatment Per the 2017 City of Renton SWDM section 1.2.8.1 A, the required treatment for the proposed commercial project is Enhanced Basic Treatment. The treatment performance goal for Enhanced Basic WQ menu is 50% reduction of total zinc and 80% removal of total suspended solids (TSS) for a typical rainfall year, assuming typical pollutant concentrations in urban runoff. The proposed enhanced treatment facility is a Filterra Bioretention Systems as approved by the City of Renton Public Works Department Blanket Adjustment dated June 26'h, 2014. The blanket adjustment allows private developments to use Filterra Systems on private property to mitigate for water quality treatment. The Washington State Department of Ecology has approved the Filterra Bioretention Systems for General Use Level Designation for Total Suspended Solids, oil and grease, and enhanced dissolved metals treatment. The proposed Filterra system has been designed and sized in accordance with the conditions specified in the City of Renton Blanket Adjustment. The Filterra unit has been sized for enhanced-basic treatment using a filter hydraulic conductivity of 24.82 inches/hour using the sand filter module in the latest version of WWHM or other Ecology-approved continuous runoff model. The model proves that the Filterra unit chosen is capable of filtering 91 percent of the influent runoff file. Further analysis and design calculations are included in the following pages.

The Washington State Department of Ecology has approved the Filterra® Bioretention Systems for General Use Level Designation for Total Suspended Solids, oil and grease, and enhanced dissolved metals treatment. The Americast Filterra® Bioretention Systems for Basic Treatment, Enhanced Basic Water Quality and/or Oil Treatment will be approved if the following conditions are met: 1. Filterra® is to be used only on commercial and/or industrial site developments where the system will be located in private property. The property owner is responsible for the maintenance and operation of the Filterra® Systems. There must be a single property owner responsible for maintenance of the Filterra Systems. 2. The Filterra® treatment facility shall not be located within City right-of-way or any easements dedicated to the City. 3.

Per the Department of Ecology approval, the total basin area, percent impervious area, and site location were used to size the system. Contech Engineered Solutions recommends using the Filterra Internal Bypass -Piped inlet configuration. The estimated costs of this system is shown above, and this includes the complete system delivered to the job site. This estimate assumes that the system is delivered with all components pre-installed. The contractor is responsible for setting the Filterra and connecting all external plumbing. The Filterra Internal Bypass -Pipe (FTIBP) system with a 6" pipe has an internal bypass capacity of 0.6 els. If the peak discharge from the drainage area is expected to exceed this rate, we recommend increasing the pipe size or utilizing an alternative configuration such as the Filterra -Standard Offine system with a downstream curb inlet structure. ©2015 Contech Engineered Solutions LLC www.conteches.com 11835 NE Glenn Widing Dr., Portland OR 97220 Toll-free: 800.548.4667 Fax: 800.561.1271 Page 1 of 1 ~-----LENGTH-----~ r ---,-tt±~tf'bA_J _ _ll.. ------~ I I L I SOR 35 INLET COUPLll'lG CAST INTO PRE CAST VAULT WALL >-------llcNGTf-1------ '¢ f-L~L _______ JL ___________ , A ' ' A A c-------LENGTH-------j A~--------~L-----------~ ' ' ' ' A ~ ' ' ' ' ar,;,.--,t..S,-- ' ' ' "' : .

Evaluation for the feasibility and applicability of prescribed flow control BMPs is provided below: 1. Full Dispersion: Not applicable. The proposed commercial development does not provide sufficient native vegetation to meet the minimum flow path requirements for full dispersion. 2. Full Infiltration of Roof Runoff: Not feasible. Full infiltration is infeasible and not required as the minimum design requirements (below) cannot be met: • "Existing soils must be coarse sands or cobbles or medium sands" - onsite glacial till soils do not exhibit infiltration characteristics that will allow full infiltration BMPs to "fully and reliably" infiltrate runoff into the ground. 3. Flow Control BMP Feasibility List: The following BMPs have been fully evaluated for feasibility and applied to the site where determined feasible as required. • Full Infiltration: Not feasible. Full infiltration is infeasible and not required as the minimum design requirements (below) cannot be met: • Existing site soils must be coarse sands or cobbles or medium sands -onsite glacial till soils do not exhibit infiltration characteristics that will allow full infiltration BMPs to "fully and reliably" infiltrate runoff into the ground. • Limited Infiltration: Not feasible. Limited infiltration is infeasible as the following minimum design requirements cannot be met: • Existing site soils may be fine sands, loamy sands, sandy loams, or loams -present onsite glacial till soils are not suitable for limited infiltration systems. • Bioretention: Not feasible. Bioretention is infeasible as the following criteria can be cited as reasons for a finding of infeasibility without further justification: Technical Information Report 4-16 LDC Job No. 16-137 • 21.) Where the field testing indicates potential bioretention sites have a measured native soil saturated hydraulic conductivity less than 0.30 inches per hour -According to Infiltration Testing Letter Report, performed by Michael Place, PE dated January 6'\ 2017, native till soils contain a measured native soil saturated hydraulic conductivity of 0. 10 to 0. 20 inches per hour. • Permeable Pavement: Feasible. Permeable pavement is feasible with the use of underdrains as specified in section C.2. 7.1. Permeable pavement is proposed in all parking stall locations (except for ADA parking stall locations), totaling 4,306 square feet. 2,400 square feet of pollution generating impervious run-on is contributing to the permeable pavement area. Summary: The total targeted impervious cover applied to permeable pavement BMP is 6,706 square feet. 4. Basic Dispersion: Not feasible. The proposed architectural site plan does not provide sufficient vegetated pervious surfaces to meet the minimum design requirements for basic dispersion concerning the minimum vegetated flowpath lengths. 5. BMP Application Rate: For projects that will result in an impervious surface coverage greater than 65% on the buildable portion of the site/lot, on-site BMPs must be applied to 20% of the target impervious surfaces or to an impervious area equal to at least 10% of the site/lot, whichever is less. • 10% of Lot= 0.1 x 65,715 = 6,571 SF • 20% of Target Impervious Surface= 0.2 x 47,720 = 9,544 SF • Summary: On-site BMPs must be applied to at least 6,571 SF of Target Impervious Surfaces Technical Information Report 4-17 LDC Job No. 16-137 Permeable Pavement Design: The proposed permeable pavement flow control BMP has been designed in accordance with the 2017 City of Renton SWDM section C.2. 7.1. The design is based on soils information presented in Infiltration Testing Letter Report prepared by PSI on January 6'h, 2017. Underdrains will be used to discharge all runoff that will not infiltrate into the native soils. Design infiltration rates range from 0.02 to 0.05 in/hr at the locations of proposed permeable pavement.

Trip Generation Calculations The trip generation calculations for the Renton Special Care Community development are based on data contained in the Institute of Transportation Engineers' (ITE ) Trip Generation Manual, 9zh Edition ~ Volume 2: Data (2 012). The average trip generation rates for lTE Land Use Code 210, Single-Family D e tached Housing, has been used for the existing unit on the s ite. The trip generation from the e x isting unit is summarized in Table 1.

The City of Renton Policy Guidelines for Traffic Impact Analysis for New Development identifies that a traffic impact analysis is only required for developments that generate 20 or more AM or PM peak-hour trips. The Renton Special Care Communitydevelopment will not exceed this threshold and therefore a full traffic impact analysis is not required. 2. Transportation Impact Fees The transportation impact fee for the Renton Special Care Community has been calculated using the latest City of Renton Fee Schedule. The City of Renton identifies a rate of $384.76 per attached dwelling for senior housing. This results in transportation impact fees of $23,085.60 for the Cottages at Renton Highlands development. It is important to note that this fee does not vest and is calculated when the building permits are applied for.
