The rectangular shaped property is owned by Renton School District (RSD) and is bound by an easement for two interstate high pressure natural gas transmission pipelines operated by Williams – Northwest Pipeline to the north (Exhibit 19), 116th Ave SE to the west and single-family residences to the east and south (Exhibit 18). The project site was first developed as Cascade Elementary School (CES) in 1964 and was later replaced in 1995 with the current structure (Exhibit 14). The parcel also includes supplemental portable classrooms, related play areas, parking, and mechanical equipment. The other government facility is proposed on the south portion of the lot. RSD will also be requesting to subdivide the 14.88-acre school property to create a separate 2.72-acre parcel for the community center. The parcel is located in the Benson Community Planning Area and has a comprehensive plan designation of Residential Medium Density (MD) and is zoned Residential-6 (R-6). The existing elementary school would remain and the biofiltration swale and associated storm piping would be removed to accommodate a new Modular Wetland System. The proposed 21,110 square foot one-story community center would be open to the general public and would offer services such as after school programs and activities, health care offices with labs, counseling services, childcare for facility users, community garden and demonstration kitchen, lunch room, locker rooms, gym, and fitness programs. The large parcel has an overall elevation drop of 13 feet from the northwest corner to the southeast corner of the site. Access to the new facility would be provided via an existing driveway at the south end of the property off 116th Ave SE and ingress and egress improvements would be completed on the next adjacent driveway to the north for two-way traffic plus a proposed Bus Only lane. Site improvements would also include 90 new onsite parking spaces and 29 shared parking spaces with the school in front of the proposed community center. A minimum 10-foot wide fully sight-obscuring landscape visual barrier would be provided along the south property line within the construction limits. No critical areas were identified on the site. The applicant is proposing to remove eight (8) significant trees on the existing parcel. The applicant is also requesting a variance to the maximum building height in the R-6 zone to 31’-3” to primarily accommodate the gymnasium use with sport courts. In addition, the applicant is requesting a street modification and waiver to retain the existing frontage improvements and a driveway design modification to allow modifications to the maximum driveway width to minimize existing traffic impacts. The proposed driveway re-configuration would consist of a 24-foot wide driveway for two-way load/unload traffic, a 14-foot wide driveway for Bus Only access lane, and an approximately 11-foot wide island that separates these two access points. Construction of the Family First Community Center is expected to begin in May 2020 and end in July 2021. The applicant submitted a Geotechnical Engineering Report, a Phase One Environmental Site Assessment, a Technical Information Report, a Tree Inventory & Retention Plan, and a Traffic Impact Study. PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS-M with a 14-day Appeal Period.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: DocuSign Envelope ID: 28C409A9-F5AA-448B-8873-F3931CE67FA8 City of Renton Department of Community & Economic Development Family First Community Center Staff Report to the Environmental Review Committee LUA19-000212, SA-A, CU-H, ECF, V-A, MOD Report of October 14, 2019 Page 4 of 8 SR_ERC_FFCC_LUA19-000212_v1 1. Earth Impacts: According to the applicant’s Geotechnical Engineering Report, prepared by The Riley Group, Inc. (RGI), dated June 8, 2018 (Exhibit 13) the site is suitable for the proposed construction from a geotechnical standpoint. According to RGI, the site is underlain by up to 11 feet of fill comprised of loose to medium dense silty sand with varying amounts of gravel over medium dense to very dense silty sand with varying amounts of gravel, and localized silty sand, sandy gravel, and sand with some silt and gravel. The Geologic Map of King County, Washington indicates that the site soil is mapped as till (Qvt). Since the site is underlain by till, the site would be considered not liquefiable and infiltration is infeasible. RGI expects that site grading would consist of cut in the high area of the site and fill in the existing storm water pond (approximately 10 feet deep) to achieve building and pavement grades and excavation for utilities (Exhibit 5). On May 23, 2018, RGI performed subsurface exploration using a tracked drill rig. A total of seven (7) test borings were advance in the proposed development area to an average depth of approximately 16 feet. RGI encountered groundwater seepage at 15 feet in two (2) of the subsurface explorations and fluctuations of the groundwater table are expected to occur and should be considered when developing due to seasonal variations in the amount of rainfall, runoff, and other factors. The project is not mapped as a coalmine hazard area. RGI recommends that the proposed building be supported on spread footings bearing on medium dense native soil or structural fill. The slab-on-grade can be similarly supported on medium dense native soil or structural fill. After stripping, grubbing, and prior to placement of structural fill, RGI recommends proofrolling building and pavement subgrades and areas to receive structural fill. Placement and compaction of structural fill should be observed by the geotechnical engineer and in-place density tests should be performed as the fill is being placed to confirm that the recommended level of compaction is achieved. RGI further recommends that preparation for site grading and construction include procedures intended to drain ponded water, control surface water runoff, and to collect shallow subsurface seepage zones in excavations where encountered. RGI concludes that it would not be possible to successfully compact the subgrade or utilize on-site soils as structural fill if accumulated water is not drained prior to grading or if drainage is not controlled during construction. Attempting to grade the site without adequate drainage control measures would reduce the amount of on-site soil effectively available for use, increase the amount of select import fill materials required, and ultimately increase the cost of the earthwork phases of the project. RGI anticipates that the use of berms and shallow drainage ditches, with sumps and pumps in utility trenches, would be required for surface water control during wet weather and/or wet site conditions. According to the SEPA Environmental Checklist, the applicant is proposing approximately 4,200 cubic yards of export material in order to prepare the site for the community center improvements (Exhibit 23). The project would result in roughly 1.7-acres of new or replaced impervious area and 1.02-acres of new or replaced pervious area within the parcel. The total project area is approximately 2.72 acres. Grading, erosion and sediment control standards of RMC 4-4-060 would mitigate dust, slope, and runoff impacts. The geotechnical report provided discussion and recommendations for site preparation and earthwork, foundations, retaining walls, slab-on-grade construction, drainage, utilities, and pavements. Due to the geotechnical recommendations included in the provided report and supplemental letter and to mitigate for potential impacts the project proposal could have on the site resulting from project construction, staff recommends as a mitigation measure that the project construction comply with the recommendations found in the submitted Geotechnical Engineering Report, prepared by The Riley Group, Inc. (RGI), dated June 8, 2018, and future addenda. Mitigation Measures: The project construction shall comply with the recommendations found in the submitted Geotechnical Engineering Report, prepared by The Riley Group, Inc. (RGI), dated June 8, 2018, and future addenda.

Air Impacts: It is anticipated that some short-term air quality impacts could be associated with site work and building construction required to develop this site. Project development impacts during construction may include dust as a result of grading and exhaust from construction vehicles and equipment. Dust control would be mitigated through the use of temporary erosion control measures, watering or other measures to remediate impacts as needed (Exhibit 24). Long-term impacts would result from the net increase of vehicular traffic. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 3. Water a. Storm Water Impacts: The applicant submitted a Technical Information Report, prepared by Coughlin Porter Lundeen, dated August 22, 2019 (Exhibit 11) with the project application. Based on the City of Renton’s flow control map, the site falls within the Flow Control Duration Standard area matching Forested Site Conditions and is within the Lower Cedar River Drainage Basin. The development would be subject to Full Drainage Review in accordance with the 2017 Renton Surface Water Design Manual (RSWDM). The TIR provides technical information and design analysis required for developing the Stormwater Drainage and Temporary Erosion and Sedimentation Control (TESC) Plans for the project and the stormwater design for the project was based on the requirements set forth by the 2017 RSWDM. The 2.72-acres designated project development area consists of a 0.6- acre parking lot, a grass field and an existing biofiltration swale on the southern side of the existing CES site. The topography generally slopes from west to east with the project site outfall located on the southeast corner of the site (Exhibit 5). The project has two high points located in the center portion of the site and at the western property line, at elevations of 464 and 465 respectively. The existing low point is located at the southeast corner of the site at an elevation of 452 feet. The overall drop across the site from the northwest corner down to the southeast corner is 13 feet. Stormwater runoff flows from north to south. The TIR Report analyzed existing conditions and proposed surface water collection and distribution. The geotechnical analysis of site soils found that the conditions onsite are not compatible with stormwater infiltration and recommended that the project not utilize infiltration, therefore, the project proposes to implement non-infiltrative bioretention, soil quality preservation, and vegetated roof to meet this requirement. Stormwater runoff from the existing site consists of surface, shallow, and piped flow to the existing biofiltration swale located on the south side of the site, which then discharges to the existing stormwater system at the southeast corner of the site. The project would be considered a “commercial” project and drains to the City of Renton Stormwater system, therefore, Enhanced Basic water quality is required for this project. The Family First Community Center project would remove the biofiltration swale that is currently being used as a water quality treatment facility for the Cascade Elementary School site. A Modular Wetland System (MWS) is proposed to be installed in order to treat the pollution generating runoff from the existing Cascade Elementary School site in replacement of the biofiltration swale. A second MWS would be used to treat the pollution generating runoff from the proposed pollution generating surfaces that would be constructed as a part of the Family First Community Center project before discharging to the existing City of Renton stormwater system. The two proprietary systems DocuSign Envelope ID: 28C409A9-F5AA-448B-8873-F3931CE67FA8 City of Renton Department of Community & Economic Development Family First Community Center Staff Report to the Environmental Review Committee LUA19-000212, SA-A, CU-H, ECF, V-A, MOD Report of October 14, 2019 Page 6 of 8 SR_ERC_FFCC_LUA19-000212_v1 proposed to treat runoff from all target surfaces and meet the water quality assessment are the SC- 310 and a MC-3500 Stormtech Chamber System. The SC-310 would provide a chamber volume of 18,415 cubic feet (CF) and the MC-3500 would provide a chamber volume of 30,087 CF. The MWSs would be sized according to flow rates or sized to treat the full 2-year release rate post detention. In the developed condition, both Stormtech Chamber systems would discharge to the existing storm system located in the southeast corner of the site. By dividing the project into two different size Stormtech Chamber detention systems, the project can utilize the existing topography to minimize earthwork. In addition, the project would include a bioretention cell for water quality treatment that would mitigate pollution generating areas and a green roof to mitigate target impervious surfaces to the maximum extent feasible (Exhibit 12). Once the project is fully developed, the project is expected to increase the amount of impervious area to 1.70 acres. Appropriate on-site BMPs would also be required to help mitigate the new runoff created by this development. The final drainage plan and drainage report would be submitted with the civil construction permit application. It is anticipated that the City’s currently adopted 2017 RSWDM would mitigate for any other potential surface water impacts that could be generated by the project proposal, therefore no further mitigation is recommended at this time. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 4. Vegetation Impacts: The project area includes approximately 2.19 acres of grass fields and native vegetation. The development would decrease the amount of pervious area and landscape to approximately 1.02 acres. The applicant’s Arborist Report, prepared by Ian Gray, City of Renton Urban Forestry & Natural Resources Manager (dated August 26, 2019; Exhibit 7), inventoried 21 trees in the vicinity of the project site. The applicant is propping to remove eight (8) significant trees (Linden and Paper Birch). Five (5) of the eight (8) trees to be removed were found to be dead. In addition, one of the poor damaged trees is located within the footprint of the proposed building. Pursuant to RMC 4-4-130.H, tree retention standards in a residential zone (specifically Residential-6 zone) require at least thirty percent (30%) significant tree retention during and post development. The applicant is proposing to retain 12 of the project area’s significant trees (Exhibit 8). The applicant is proposing to enhance the existing landscaping onsite by planting 83 new trees, including deciduous trees (14-October glory maple, 17-sour gum), evergreen trees (6-Austrian black pine, 12 Douglas fir, 9-hogan cedar), and accent trees (14-vine maple, 4-Persian parrotia, and 7-Japanese stewartia). The proposed new trees would planted and irrigated throughout the project site (Exhibits 6 and 9). Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 5. Environmental Health a. Noise Impacts: Short-term construction activity-related noise impacts would primarily result from the preparation of the building site and construction of the new structure. Construction activity hours are restricted to the hours between seven o’clock (7:00) a.m. and eight o’clock (8:00) p.m., Monday through Friday. Work on Saturdays shall be restricted to the hours between nine o’clock (9:00) a.m. and eight o’clock (8:00) p.m. No work shall be permitted on Sundays. Haul hours shall be restricted to the hours between eight-thirty (8:30) a.m. and three-thirty (3:30) p.m., Monday through Friday unless otherwise approved in advance by the Development Services Division. All noise levels would be required to comply with City of Renton code (Chapter 7 Noise Level Regulations) and Washington State code (WAC 173-60-040). The anticipated temporary noise DocuSign Envelope ID: 28C409A9-F5AA-448B-8873-F3931CE67FA8 City of Renton Department of Community & Economic Development Family First Community Center Staff Report to the Environmental Review Committee LUA19-000212, SA-A, CU-H, ECF, V-A, MOD Report of October 14, 2019 Page 7 of 8 SR_ERC_FFCC_LUA19-000212_v1 impacts would be those commonly associated with a community center and elementary school. Therefore, typical noise levels from Family First Community Center are anticipated to result in a less- than-significant noise impact. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 6. Aesthetics Impacts: The applicant is proposing a single story 21,100 square foot community center. The development would include parking, landscaping and utility improvements. The applicant is requesting a building height variance to the maximum 24-foot wall plate height in the R-6 zone to 31’-3”. The additional height is necessary to accommodate the gymnasium use. The building construction type proposed is V-B and the building would be a sustainable design with the goal of Leed Silver. The proposed building would feature heavy timber wood framing and natural light and building materials would include wood frame construction, glulam beams and columns, metal siding for exterior walls, fiberglass windows and PVC roof membrane (Exhibits 15-17). The proposed building would be compatible to the adjacent CES. Bulk and scale reduction methods include perimeter and interior landscaping around the building and parking area. The building would also include increased building setback from the existing property line with over a 160-foot setback from 116th Ave SE, over a 65-foot setback from the south property line, and over a 230-foot setback from the east property line. The community center would also provide over a 60-foot separation distance from the southeast corner of the existing elementary school. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 7. Transportation Impacts: A Traffic Impact Study, prepared by TENW, dated May 29, 2019 (Exhibit 21), was submitted with the project application. The submitted report indicated that at full build-out the proposed development would generate 669 average daily trips (ADT) with 46 AM peak-hour vehicular trips (32 entering and 14 exiting) and 54 PM peak-hour vehicular trips (23 entering and 31 exiting). Access to the new facility would be provided via an existing driveway at the south end of the property off 116th Ave SE and ingress and egress improvements would be completed on the next adjacent driveway to the north for two-way traffic plus a proposed Bus Only lane for improved access and circulation. Onsite improvements would also include 90 new onsite parking spaces and 29 shared parking spaces with the elementary school. The shared parking spaces and contained parent drop-off/pick-up area would be maintained at its current location but contained to avoid conflict with the primary access for the proposed community center. During non-peak school periods, the driveway restrictions from the southern parking lot can be removed/opened by the School District and the Family First Community Center or school can utilize the parking lot as needed. These recommendations are overviewed in Figure 9 of the Traffic Impact Study. The applicant is requesting a modification and a waiver from street frontage improvements along 116th Ave SE. The City of Renton’s 2018-2023 Capital Improvement Program identifies planned transportation improvements for 116th Ave SE roadway (Puget Drive SE to Southern City Limits) – widen roadway from two (2) lanes to three (3) lanes with bicycle lanes along 116th Ave SE and Edmonds Way SE, including new pavement, curb, gutter, sidewalk, street lights, traffic signals, storm drainage, channelization and landscaping. Phase 1 improvements from SE Petrovitsky Rd to SE 168th St (south of the project site) are programmed for 2019 to 2023. Future phases would be developed for scoping, cost and schedule by City of Renton staff. Future improvements would enhance vehicular, bicycle and pedestrian safety along this north-south transportation corridor.

The proposed project would be responsible for the payment of a Transportation Impact Fee at the time of Building Permit issuance (unless the fee is waived or reduced by Renton City Council). The applicant’s parking study, included in the Traffic Impact Study, indicated that the 90 new onsite parking spaces, combined with the 29 shared parking spaces with the school in front of the proposed community center would comply with the peak development parking demand and no parking spillover is anticipated. As a result, it is anticipated that through the payment of applicable Transportation Impact Fees, the addition of the 90 new onsite parking spaces, the improvement to the shared parking, and the reconfiguration of the of parent drop-off/pick-up operations would adequately mitigate additional traffic generated by the project; therefore, no further mitigation is recommended.

Read, PE, Principal, TENW SUBJECT: Family First Community Center – Traffic Impact Study TENW Project No. 3612 This memorandum summarizes the results of a traffic impact analysis for a proposed development known as Family First Community Center, which would construct an approximate 22,000 square foot building with 18,300 square feet dedicated to a recreational community center and roughly 3,700 square feet dedicated to a community health clinic. Currently, approximately 133 new on-site parking stalls (112 are net new stalls) would be constructed at 16022 116th Avenue SE in Renton, WA. The project proposes to provide all access via two existing site access driveways onto 116th Avenue SE that would be shared with the adjacent Cascade Elementary School (CES) located north of the project site. Project Description The proposed development is located at 16022 116th Avenue SE in Renton, WA. A new 22,000 square foot recreational community center and 3,700 square feet community health clinic would be constructed with a total of 136 new on-site parking stalls with 112 net new stalls (21 existing parking stalls would be reconstructed as part of the development to provide 38 on-site parking stalls). The total size of the building would be approximately 22,000 square feet. Site access would be provided via two existing site access driveways (Center and South Driveways) onto 116th Avenue SE that would be shared with the adjacent Cascade Elementary School (CES) located north of the project site, but controlled by a gate during peak school arrival/dismissal periods. A loading area would be provided on the south side of the new community center building. A site vicinity map is provided in Figure 1 and a conceptual site plan is illustrated in Figure 2. Existing Transportation Conditions This section includes an inventory of existing roadway conditions, existing peak hour traffic volumes, intersection levels of service, Cascade Elementary School arrival-dismissal period observations, public transportation services, nonmotorized facilities and planned transportation improvements. DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: October 10, 2019 TO: Clark Close, Senior Planner FROM: Brianne Bannwarth, Development Engineering Manager SUBJECT: Traffic Concurrency Test – Family First Community Center; LUA19-000212 The applicant, City of Renton, is requesting Administrative Site Plan Review, Hearing Examiner Conditional Use Permit review, Height Variance, Driveway Design Modification, Street Modification and Waiver, and Environmental (SEPA) Review to construct a community center (Family First Community Center) at 16022 116th Ave SE (APN 2823059034). The other government facility is proposed on the south portion of Renton School District’s (RSD) Cascade Elementary School in the Benson Community Planning Area. RSD will also be requesting to subdivide the 14.88-acre school property to create a separate 2.72-acre parcel for the community center. The existing site is zoned Residential-6 (R-6) and is currently occupied by Cascade Elementary School, supplemental portable classrooms, and related play areas, parking, and mechanical equipment. The existing elementary school would remain and the biofiltration swale and associated storm piping would be removed to accommodate the new Modular Wetland System. The proposed 21,110 square foot one-story community center would be open to the general public and would offer services such as after school programs and activities, health care offices with labs, counseling services, childcare for facility users, community garden and demonstration kitchen, lunch room, locker rooms, gym, and fitness programs. The large parcel has an overall elevation drop of 13 feet from the northwest corner to the southeast corner of the site. Access to the new facility would be provided via an existing driveway at the south end of the property off 116th Ave SE and ingress and egress improvements would be completed on the next adjacent driveway to the north for two-way traffic plus a proposed Bus Only lane. Site improvements would also include 90 new onsite parking spaces and 29 shared parking spaces with the school in front of the proposed community center. A 10 -foot wide fully sight-obscuring landscape visual barrier would be provided along the south property line within Transportation Concurrency Test – Family First Community Center Page 2 of 3 October 10, 2019 the construction limits. No critical areas were identified on the site. The applicant is proposing to remove eight (8) significant trees on the existing parcel. The applicant is also requesting a variance to the maximum building height in the R-6 zone to 31’- 3” to primarily accommodate the gymnasium use with sport courts. The applicant is also requesting a street modification and waiver to retain the existing frontage improvements and a driveway design modification to allow modifications to the maximum driveway width to minimize existing traffic impacts. The proposed driveway re-configuration would consist of a 24-foot wide driveway for two-way load/unload traffic, a 14-foot wide driveway for Bus Only access lane, and an approximately 11-foot wide island that separates these two access points. Construction of the Family First Community Center is expected to begin in May 2020 and end in July 2021. The applicant submitted a Geotechnical Engineering Report, a Phase One Environmental Site Assessment, a Technical Information Report, a Tree Inventory & Retention Plan, and a Traffic Impact Study. The proposed development would generate approximately 669 net new average weekday daily trips. During the weekday AM peak hour, the project would generate approximately 46 net new trips (32 inbound and 14 outbound). During the weekday PM peak hour, the project would generate approximately 54 net new trips (23 inbound and 31 outbound). The proposed project passes the City of Renton Traffic Concurrency Test per RMC 4-6-070.D as follows: Traffic Concurrency Test Criteria Pass Implementation of citywide Transportation Plan Yes Within allowed growth levels Yes Project subject to transportation mitigation or impact fees Yes Site specific street improvements to be completed by project Yes Traffic Concurrency Test Passes Evaluation of Test Criteria Implementation of citywide Transportation Plan: The City’s investment in completion of the forecast traffic improvements is 130% of the scheduled expenditure through 2020. Within allowed growth levels: As shown on the attached citywide traffic concurrency summary, the calculated citywide trip capacity for concurrency with the city adopted model for 201 9 is 1,711 trips, which provides sufficient capacity to accommodate approximately 54 additional trips from this project. A resulting 1,657 trips are remaining. Transportation Concurrency Test – Family First Community Center Page 3 of 3 October 10, 2019 Project subject to transportation mitigation or impact fees: The project will be subject to transportation impact fees at time of building permit for the project. Site specific street improvements to be completed by project: The project has requested a waiver to construct frontage improvements and install a wider driveway. City staff is in support of the requested waiver provided all ramps along the property street frontage are brought up to current ADA standards and right of way dedication is provided for the future street improvements. Frontage improvements will be required to be completed prior to occupancy of the building. Any additional off-site improvements identified through SEPA or land use approval will also be completed prior to final occupancy. Background Information on Traffic Concurrency Test for Renton The City of Renton Traffic Concurrency requirements for proposed development projects are covered under Renton Municipal Code (RMC) 4-6-070. The specific concurrency test requirement is covered in RMC 4-6-070.D, which is listed for reference: D. CONCURRENCY REVIEW PROCESS: 1. Test Required: A concurrency test shall be conducted by the Department for each nonexempt development activity. The concurrency test shall determine consistency with the adopted Citywide Level of Service Index and Concurrency Management System established in the Transportation Element of the Renton Comprehensive Plan, according to rules and procedures established by the Department. The Department shall issue an initial concurrency test result describing the outcome of the concurrency test. 2. Written Finding Required: Prior to approval of any nonexempt development activity permit application, a written finding of concurrency shall be made by the City as part of the development permit approval. The finding of concurrency shall be made by the decision maker with the authority to approve the accompanying development permits required for a development activity. A written finding of concurrency shall apply only to the specific land uses, densities, intensities, and development project described in the application and development permit. 3. Failure of Test: If no reconsideration is requested, or if upon reconsideration a project fails the concurrency test, the project application shall be denied by the decision maker with the authority to approve the accompanying development activity permit application. The Concurrency Management System established in the Transportation Element on page XI -65 of the Comprehensive Plan states the following: Based upon the test of the citywide Transportation Plan, consideration of growth levels included in the LOS-tested Transportation Plan, payment of a Transportation Mitigation Fee, and an application of site specific mitigation, development will have met City of Renton concurrency requirements. SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 1 of 14 SEPA ENVIRONMENTAL CHECKLIST Purpose of checklist: Governmental agencies use this checklist to help determine whether the environmental impacts of your proposal are significant. This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use “not applicable” or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision- making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Instructions for Lead Agencies: Please adjust the format of this template as needed. Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals: For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please completely answer all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead agency may exclude (for non-projects) questions in Part B - Environmental Elements –that do not contribute meaningfully to the analysis of the proposal. A. Background [HELP] 1.

DEPARTMENT OF COMMUNITY & ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: October 10, 2019 TO: Clark Close, Senior Planner FROM: Brianne Bannwarth, Development Engineering Manager SUBJECT: Utility and Transportation Comments for Family First Community Center 16022 116th Avenue SE LUA19-000212 I have reviewed the application for the Family First Community Center at 16022 116th Avenue SE (APN 2823059034). The project proposes to construct a 27,000 square foot recreational center with 120 surface parking stalls. The following are the civil review comments for the proposed project: EXISTING CONDITIONS The site is approximately 14.9 acres in size and is rectangular in shape. Cascade Elementary School with associated parking lot resides on the west portion of existing property and the remaining portion is open fields with lawn. Water Water service is provided by Soos Creek Water and Sewer District. Sewer Wastewater service is provided by the Soos Creek Water and Sewer District. Storm There is an existing storm drainage system in 116th Avenue SE. Stormwater runoff from the existing site consists of surface, shallow, and piped flow to the existing biofiltration swale located on the south side of the site, which then discharges to the existing stormwater system at the southeast corner of the site as defined by the project Technical Information Report dated August 22, 2019 prepared by Coughlin Porter Lundeen. Streets 116th Avenue SE is a Minor Arterial Street with an existing right of way (ROW) width of 60 feet as measured using the King County Assessor’s Map. The pavement width is 35 feet (two 11-foot lanes with 7 foot shoulder on the west side of the roadway) with a 0.5-foot curb, 6-foot planter strip, and 5-foot sidewalk on the west side of the roadway. Family First Community Center – LUA19-000212 Page 2 of 6 October 10, 2019 CODE REQUIREMENTS WATER 1. Please obtain a water availability certificate from Soos Creek Water and Sewer District and provide it with the construction permit submittal. 2. Review of the water plans will be conducted by Soos Creek Water and Sewer District and the Renton Regional Fire Authority. 3. Plans approved by Soos Creek Water and Sewer District shall be routed to the City for final review prior to permit issuance. SEWER 1. Please obtain a sewage availability certificate from Soos Creek Water and Sewer District and provide it with the construction permit submittal. 2. Review of the sewage plans will be conducted by Soos Creek Water and Sewer District. 3. Plans approved by Soos Creek Water and Sewer District shall be routed to the City for final review prior to permit issuance. SURFACE WATER 1. A geotechnical report, dated June 8, 2018, completed by Riley Group, Inc. for the site has been provided. Erosion control measures will need to be in place prior to starting grading activities on the site. The report discusses the soil and groundwater characteristics of the site including a very brief discussion regarding the infiltration potential and provide recommendations for project design and construction. The report notes that the site is underlain by up to 11 feet of fill material. Geotechnical recommendations presented need to be address within the project plans. 2. A Preliminary Drainage Plan and Technical Information Report (TIR), dated August 22, 2019, was submitted by Coughlin Porter Lundeen with the Land Use Application. Based on the City of Renton’s flow control map, the site falls within the Flow Control Duration Standard area matching Forested Site Conditions and is within the Lower Cedar River Drainage Basin. The development is subject to Full Drainage Review in accordance with the 2017 Renton Surface Water Design Manual (RSWDM). All nine core requirements and five out of the six special requirements discussed in the Technical Information Report. a. Discharge at the Natural Location, RSWDM Core Requirement #1: The existing project site’s surface water discharges to an existing conveyance system located at the southeast portion of the site. The surface water is then directed to the storm drainage system within the adjacent residential neighborhood. b. Off-site Analysis, RSWDM Core Requirement #2: The project off-site analysis evaluated the upstream and downstream area. The analysis identified that there were no downstream concerns. c. Flow Control, RSWDM Core Requirement #3: The proposed detention system shall be designed in accordance with the RSWDM that is current at the time of civil construction permit application. Separate structural plans will be required to be submitted for review and approval under a separate building permit for the detention system ensuring that system can withstand fire truck loading. Special inspection from the building department is required. The project proposes two Family First Community Center – LUA19-000212 Page 3 of 6 October 10, 2019 proprietary detention Stormtech Chamber system (SC-310 and MC-3500) to address the flow control requirements. The following are items that will need to be addressed as part of the Civil Construction Permit Application: i. In accordance with the Flow Control Duration Standard Matching Forested Site Conditions, the developed mitigated 2-year and 10-year peak flow rates shall match the pre-developed (forested) 2-year and 10- year peak flow rates. Additionally, the developed mitigated flow duration extending from 50% of the 2-year to the full 50-year flow must match the pre-developed (forested) condition. ii. Targeted area not able to be routed to the detention vault shall be modeled as bypass area (i.e. unmitigated flow directed to the projects downstream point of compliance). This includes the slope area that is surrounding the parking lot on the east side of the development. iii. Lid and access panels for the detention vault shall be located outside of the ADA paths and stalls. iv. Applicant shall provide flow control model calculations to verify that the storage volume proposed can adequately mitigate created flows. d. Conveyance, RSWDM Core Requirement #4: All new conveyance systems constructed as part of the project must be sized to RSWDM standards for the total tributary area (onsite and offsite) that the storm systems serve. i. Pipe connects into the proposed structures shall be evaluated for constructability as part of the Civil Construction Permit Applications. Details of structure connections shall be provided. e. Core Requirements #5 through #7: Core Requirements shall be fully addressed as part of the Civil Construction Permit Application. f. Water Quality, RSWDM Core Requirement #8: Based on the commercial use of the project, Enhanced Basic Water Quality Treatment is required. The project proposes to use two proprietary system to meet the water quality assessment. One of the system will replace the existing bioretention swale providing water quality for the existing site impervious area. The second will be downstream of the proposed detention system for the proposed improvements. i. Applicant shall provide model calculations showing the required volume to be treated by the water quality facilities, per Core Requirement 8. . g. Onsite BMPs, RSWDM Core Requirement #9: Appropriate on-site BMPs will be required to help mitigate the new runoff created by this development. A preliminary drainage plan, including the application of on-site BMPs, has been included with the land use application. Infiltration has been determined to be infeasible based on the fill material on site, therefore, the project proposes to implement non-infiltrative bioretention, soil quality preservation, and vegetated roof to meet this requirement. The final drainage plan and drainage report must be submitted with the civil construction permit application. i. Final evaluation of the application of on-site BMPs to the maximum extent feasible will be completed during civil construction permit review. The applicant may be required to apply additional on-site BMPs in order to meet the minimum requirements outlined in Core Requirement #9. ii. Non-infiltrative bioretention (bioretention with underdrain) does not meet the requirements of Core Requirement #9, unless approved via an Family First Community Center – LUA19-000212 Page 4 of 6 October 10, 2019 adjustment per Section 1.4 of the RSWDM that, at minimum, addresses comparable hydraulic performance, water quality concerns, and maintainability. iii. Permeable pavement is deemed infeasible in the TIR, yet the design plans call out pervious concrete parking stalls. h. Aquifer Protection Area, RSWDM Special Requirement #6: The existing site is outside of the City’s Aquifer Protection Area, however, the Technical Information Report shall be revised as part of the Civil Construction Permit Application to address this requirement. 3. The current City of Renton Surface Water Standard Plans that shall be used in all drainage submittals are available online at the City of Renton website. 4. A Construction Stormwater General Permit from Department of Ecology will be required since grading and clearing of the site exceeds one acre. A Stormwater Pollution Prevention Plan (SWPPP) is required for this site. 5. Surface water system development fee is $0.720 per square foot of new impervious surface, but not less than $1,800.00. This is assessed based on the final approved civil construction plans and payable prior to issuance of the construction permit. TRANSPORTATION 1. The transportation impact fee that is current at the time of building permit application will be levied, payable at issuance of building permit. 2. The proposed development fronts along 116th Avenue SE, a Minor Arterial street. Existing right-of-way (ROW) width is approximately 60 feet. The City’s Transportation Division has established a corridor plan for this section of 116th Ave SE. The corridor determined by the City’s Transportation Division which supports recommendations in the Benson Hill Community Plan, requires a right-of-way width of 71-ft. The paved roadway section is 44- ft, consisting of two 11-ft travel lanes, one 12-ft center turn lane, and two 5-ft bike lanes. A 0.5-ft vertical curb, 8-ft planter and 5-ft sidewalk are required along each side of the roadway. Dedication of 5.5-ft of right-of-way would be required. a. The applicant submitted a waiver request as part of the land use application to maintain the existing roadway improvements fronting the subject property. Community and Economic Development Staff in conjunction with Pubic Works Transportation staff have reviewed the street waiver request. Staff recommends approval of the waiver given that the existing street section meets the transportation needs for connectivity, pedestrian access, and separation between vehicular and pedestrian movements. Staff does recommend a condition of approval to dedicate the required 5.5-feet right of way required to complete the proposed corridor plan and upgrading all of the existing driveway curb ramps along the west property line to meet current ADA requirements. 3. Transportation Engineering NorthWest (TENW) provided a transportation memorandum dated February 13, 2019. The site generated traffic volumes were calculated using data from the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition, (2017). The TIA evaluated traffic operations at seven intersections around the site. The intersections evaluated during the PM Peak Hour were: a. 116th Avenue SE / S Puget Drive / Royal Hills Drive SE b. 116th Avenue SE / SE 22nd Street c. 116th Avenue SE / SE 164th Street Family First Community Center – LUA19-000212 Page 5 of 6 October 10, 2019 d. 116th Avenue SE / SE Petrovitsky Road e. 116th Avenue SE / Project North Driveway (AM Peak Hour as well) f. 116th Avenue SE / Project Center Shared Site Driveway (AM Peak Hour as well) g. 116th Avenue SE / Project South Shared Site Driveway (AM Peak Hour as well) The intersections were evaluated using Level of Service (LOS) methodology under existing conditions, existing plus project conditions, and project opening year conditions. LOS evaluation was done in accordance with the industry standard 2010 Highway Capacity Manual (HCM). Study intersections were visited by Idax Data Solutions in May 2018 during the AM and PM Peak periods. Traffic counts were done between 7:00 AM and 9:00 AM and between 4:00 PM and 6:00 during the weekday. From this data, existing LOS was determined for each intersection. The report concludes that in the existing condition, each intersection operates at LOS D or better. It was noted that the circulation of pedestrians and vehicles during the peak arrival and dismissal periods are not operating efficiently. Project trip generation was completed using the 10th Edition of the Institute of Transportation Engineers (ITE) trip generation manual. The 10th Edition of the ITE manual is the industry and City standard for determining trip generation. The Recreational Community Center use (Code 495) and Clinic use (Code 630) were used for the proposed trip generation. The Family First Community Center is projected to generate approximately 46 AM net new AM peak hour trips, 54 PM peak hour trips, and 669 net new daily trips. New trip distribution was projected for the AM and PM peak hours. Trips were assigned to the existing City streets at the study intersections based on field observations by TENW and the proposed configuration of the parking lot and site circulation. City staff has reviewed the trip generation and trip assignment and found that the tables in the report do not match the tables referenced in the Attachments. Please reconcile values and provide updated impact fee calculations based on the actual trip values. Using the trip assignments, the LOS for the existing plus project conditions was determined for each intersection. The report concludes that in the existing plus project condition, the signalized, unsignalized intersection, and the minor street driveway approaches are projected to operate at acceptable LOS. The report identifies several recommendations related to the arrival and dismissal periods to help with circulation including:  Restricting parent’s drop-off/pick-up operations on-site within the existing southern parking lots,  Reconfiguring the parking lot to provide more perpendicular parking and “by- pass” lane to accommodate peak dismissal periods, and  Consolidate the central drive providing a more elongated on-site queuing area. City staff is in support of the recommendations identified in the Transportation Impact Analysis. Family First Community Center – LUA19-000212 Page 6 of 6 October 10, 2019 Driveway sight distance was evaluated at the two existing site driveways (center and south driveways) are anticipated to meet minimum AASHTO entering and stopping sight distance requirements. 4. 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. 5. The project exceeds 5,000 square feet of new additional building, therefore, street lighting will be required along 116th Avenue SE as per RMC 4-6-060. 6. If frontage improvements are required, undergrounding of utilities along 116th Avenue SE will be required as per the requirements of RMC 4-6-090. 7. Paving and trench restoration within the City of Renton right of way shall comply with the City’s Restoration and Overlay requirements. The document is available at https://edocs.rentonwa.gov/Documents/0/edoc/1074326/Trench%20Restoration%20a nd%20Street%20Overlay%20Requirements.pdf. 8. Parking lot construction shall be in accordance with City code 4-4-80G.Street lighting and street trees are required to meet current city standards. Lighting plans are required to be submitted with the land use application and will be reviewed during the construction utility permit review. 9. Transportation Concurrency under separate cover. GENERAL COMMENTS 1. All existing and proposed utility lines (i.e. electrical, phone, and cable services, etc.) along property frontage or within the site must be underground. The construction of these franchise utilities must be inspected and approved by a City of Renton inspector. 2. Maximum exposed retaining wall height is 6-ft and shall be setback a minimum of 3-ft from the right-of-way as outlined in RMC 4-4-040 – Fences, Hedges and Retaining Walls. 3. Adequate separation between utilities as well as other features shall be provided in accordance with code requirements. a. 7-ft minimum horizontal and 1-ft vertical separation between storm and other utilities is required with the exception of water lines which require 10-ft horizontal and 1.5-ft vertical. b. The stormwater line should be minimum 5 feet away from any other structure or wall or building. c. Trench of any utility should not be in the zone of influence of the retaining wall or of the building. 4. A civil construction permit for the site, utility and street improvements will require a separate plan submittal. Civil construction plans shall conform to the City Renton Drafting Standards. A licensed Civil Engineer shall prepare the civil plans. Please visit the City’s website for submittal requirements: https://rentonwa.gov/cms/One.aspx?portalId=7922741&pageId=9687014 5.
