See also http://bit.ly/2ITCGni PROJECT DESCRIPTION: The applicant, Washington Charter School Development (WCSD) previously applied for a Hearing Examiner Conditional Use Permit, Site Plan Review, and Environmental (SEPA) Review to renovate a vacant grocery store (former QFC) within the Cascade Village Shopping Center to a new 7th– 12th grade school, also known as “Excel Public Charter School” (Excel). During the City review process, the Excel school decided not to open at this location and no longer pursue land use approval for the project. WCSD is now working with a new charter school operator in order to locate in the building. The applicant, Washington Charter School Development (WCSD), is requesting a Hearing Examiner Conditional Use Permit, Site Plan Review, and Environmental (SEPA) Review to renovate a vacant grocery store (former QFC) within the Cascade Village Shopping Center to a K – 12th grade public school for Excel Public Charter School (Excel). The roughly 40,664 square foot building is located at 17060 116th Ave SE. The parcel is approximately 13.6 acres (APN 2823059009) and is zoned Commercial Arterial (CA). The project is proposing to retain 60 existing parking spaces for school use and convert several existing parking spaces (and some landscape areas) to bus loading and outdoor play. As a public charter school it is tuition free and open to all students. The school would serve up to 500 students. The school day starts at 7:30 am (Monday – Friday) and ends at slightly varied times in the afternoon, ranging from 2:30 pm to 3:40 pm. Afterschool clubs and tutoring last until 4:15 pm (Monday – Thursday). The school seeks to occupy the existing structure by fall of 2020. Renovations would include interior tenant improvements, seismic upgrades, new mechanical and electrical systems, envelope improvements, and overall site improvements. The existing surface parking area would be used for school parking. No critical areas are present on the project site. The applicant submitted a Drainage Report, Geotechnical Report, and Traffic Study with the application. Appeals of the environmental determination must be filed in writing on or before 5:00 p.m. on October 11, 2019, together with the required fee with: Hearing Examiner, City of Renton, 1055 South Grady Way, Renton, WA 98057. Appeals to the Examiner are governed by City of RMC 4-8-110 and information regarding the appeal process may be obtained from the Renton City Clerk’s Office, (425) 430-6510.

The 40,664 square foot building is located at 17060 116th Ave SE. The parcel is approximately 13.6 acres (APN 2823059009). The site is zoned Commercial Arterial (CA) and is located in the Urban District D Overlay. The applicant proposes to provide 60 parking spaces in the existing parking lot and convert several existing parking spaces (and some landscape areas) to bus loading and outdoor sport courts. The school would serve approximately 525 students. The school day would start at 8:00 am (Monday – Friday) and end at 3:30 pm. Afterschool clubs and tutoring may start as early as 7:00 am and end as late as 5:00pm (Monday – Thursday). The school seeks to occupy the existing structure by fall of 2020. Renovations would include interior tenant improvements, seismic upgrades, new mechanical and electrical systems, envelope improvements, landscaping and overall site improvements. The size of the building would not increase as a result of the project. Approximately 2,300 sq. ft. of new or replaced impervious surface is proposed.

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. B. Mitigation Measures 1. The applicant shall conduct a security survey of the site with a Renton Police Crime Prevention Representative prior to the issuance of the Certificate of Occupancy. 2. The applicant shall submit a traffic management plan with the Civil Construction Permit application for review and approval by the Public Works Plan Reviewer. C. Exhibits Exhibit 1: Environmental Review Committee (ERC) Report Exhibit 2: Neighborhood Detail Map Exhibit 3: Site Plan Exhibit 4: Floor Plans Exhibit 5: Landscape Plan Exhibit 6: Traffic Study (dated July 15, 2019 and prepared by Heffron Transportation Inc) Exhibit 7: Drainage Report (dated February 15, 2018 and prepared by Sitewise Design PLLC) Exhibit 8: Geotechnical Report (dated February 12, 2019 and prepared by GeoResources) Exhibit 9: Architectural Elevations 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: 1. Water a. Storm Water Impacts: A 12-inch stormwater main is located in 116th Ave SE. No private stormwater conveyance system is located on the project site. The existing roof drainage is collected via roof downspouts and sheet flows through the parking lot into the public conveyance system in the street. The applicant has indicated that the project would result in approximately 2,198 square feet of new or replaced impervious surface. Therefore, a full drainage review pursuant to the 2017 Renton Surface Water Design Manual is required to be submitted at the time of Construction Permit application submittal. A Surface Water System Development (SDC) fee would be assessed at a rate of $0.641 per square foot of new impervious surface, to be no less than $1,508.00, at the time of construction permit issuance. Staff anticipates that existing stormwater requirements and impact fees would adequately City of Renton Department of Community & Economic Development K-12 Public Charter School Staff Report to the Environmental Review Committee LUA19-000035, ECF, CU-H, SH Report of September 18, 2019 Page 3 of 4 SR_K-12 Public Charter School_190918_v2_FINAL mitigate any impacts created by the increase or replacement of impervious surface, therefore no further mitigation is recommended. Mitigation Measures: None Nexus: N/A 2. Fire & Police Impacts: The City of Renton Police Department provided a comprehensive set of comments and suggestions related to safety and security for the new school, applicable during both the construction and school operation phases (see Exhibit 10). Recommendations are primarily related to physical improvements such as the provision of adequate exterior lighting, installation of reinforced doors and windows, monitoring security alarms, and installation of territorial landscaping designed to create a clear boundary between public and private space. In addition, specifications for staff and pedestrian access control and lockdown procedures are also included in the recommendations. In addition to creating a safe environment in the school for teachers and students, adhering to the recommendations helps ensure the safety of City of Renton police officers should they need to respond to the school for any reason. Therefore, staff recommends as a mitigation measure that the applicant conduct a security survey of the site with a Renton Police Crime Prevention Representative of the premises prior to the issuance of the Certificate of Occupancy. Mitigation Measures: The applicant shall conduct a security survey of the site with a Renton Police Crime Prevention Representative of the premises once construction is complete. Nexus: SEPA Environmental Review 3. Transportation Impacts: The applicant submitted a Transportation Technical Report prepared by Heffron Transportation Inc. (Exhibit 6). The report included analysis related to site access and circulation, trip generation, parking needs and impact fees for the proposed new school. The consultant utilized recent traffic counts to evaluate the potential impact of the proposed project on the Level of Service (LOS) of multiple intersections near the project site. The report concluded that while the proposal would generate additional vehicle trips and delays at all studied intersections, the increase would be small relative to existing traffic volumes and would not result in any LOS decreases in the surrounding area. The consultant estimates that the school would generate approximately 1,300 new daily trips, the majority of which would occur outside of the commuter AM and PM peak hours. In comparison to the previous use on the site, a large supermarket, the proposal would generate a significantly lower number of trips (1,200 vs. 5,183 trips). The project site currently has five points of ingress/egress including three driveways off of 116th Ave SE, one driveway off of SE 168th St, and one driveway off of SE 170th St. The report recommends that the applicant create a traffic management plan that requires vehicular traffic at the proposed school to utilize the northern and southern most access points off of 116th Ave SE. This would be achieved by blocking certain entrances via a gate, utilizing pavement striping that directs the school traffic to a specific driveway, and providing education to bus drivers, parents, and students on the preferred way to enter and exit the site. The report concludes that utilization of the two preferred entrances of 116th Ave SE would be safest due to fewer opportunities for vehicular and pedestrian movement conflicts. Therefore, staff recommends as a mitigation measure that the applicant submit a traffic management plan with the Civil Construction Permit application for review and approval by the Public Works Plan Reviewer. Staff has reviewed the report and concurs with the analysis and recommendations made regarding access, circulation, and trip generation. Payment of the required impact fees would adequately mitigate the expected traffic impacts of the project and therefore no further mitigation is recommended.

The site location is shown on the Site Location Map, included as Figure 1. Our understanding of the project is based on our conversations with Ms. Anna Johnson with Washington Charter School Development, our review of the conceptual Site Plan by Miller Hayashi Architects, LLC dated April 30, 2018, our review of the Survey Plan by Puget Sound Surveying, Inc. dated October 31, 2017, our December 14, 2018 site visit and subsurface explorations, and our experience in the City of Renton area. We understand that the development will consist of a structural retrofit of the existing building and improvements to the parking area. You are proposing to convert the old grocery store into a new school building that will include a new awning area in the front and a playground area in the existing parking area. You are currently planning to keep the existing building and its foundations. Portions of the current parking area that is impervious will be converted to landscape areas. We anticipate that any new additions or structures will be a one or two-story, steel framed structure likely founded on conventional shallow foundations, similar to the existing building. The site is currently developed with a storm system and all other typical utilities and you are not proposing to increase the impervious area at the site and are actually decreasing it.
