Sandler, Benchmark Development Company, 5020 141st Avenue SE, Bellevue, WA 98006 Project Location: 17816 108th Avenue SE (Parcel No. 322305-9054) Project Summary: The applicant is requesting Hearing Examiner Site Plan approval, Environmental (SEPA) Review, a Parking Modification, and a Street Modification for the construction of a new 7,796 square foot building proposed to house a dental office. The project site totals 36,927 square feet in area and is located within the Commercial Arterial (CA) zone and Urban Design District D. Access to the site is proposed via one curb cut off of 108th Avenue SE. A surface parking lot with a total of 49 spaces (10 more than the maximum permitted by City code) and associated landscaping is proposed. A 60- foot conservation easement located on the eastern portion of the project site (adjacent to the surrounding single family residentially zoned properties) would not be impacted as a result of the proposed project. An existing W endy's building would be removed from the project site. No critical areas are mapped on the project site. Exist. Bldg. Area SF: 3,095 sf (to be removed) Proposed New Bldg.

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. Earth Impacts: A Geotechnical Report, prepared by Geotech Consultants, Inc., dated April 11, 2017 (Exhibit 2) was submitted with the project application. According to the geotechnical report (Exhibit 2), the topography of the project slopes gently from east to west with a total elevation change of 12 feet across the site. Subsurface conditions were explored through the drilling of three borings on the project site. Samples were taken using a truck mounted, hollow-stem auger drill. The borings were conducted in the area of the proposed building and encountered 2.5 to 4.5 feet of medium-dense, gravelly silty sand fill overlying native, medium-dense, silty sand. The underlying native soils became dense to very dense at 5.5 to 6 feet below existing ground surface. Very dense silty sand extended to the maximum-explored depth of 15.9 feet. Perched groundwater seepage was observed on top of the City of Renton Department of Community & Economic Development Environmental Review Committee Report RENTON DENTAL ARTS LUA17-000289, ECF Report of June 26, 2017 Page 3 of 4 ERC Report_Renton Dental Arts native soils at depths of 2.5 to 3.5 feet in Borings 2 and 3. Several perched groundwater layers were also observed in more permeable layers within the underlying silty sand at depths ranging from 8.5 to 13 feet. The report concludes that the site is compatible with the planned development and the native soils or structural fill placed on top of native soils should provide adequate support for conventional foundations. The report included recommendations regarding earthwork and structural fill, foundations and retaining walls, seismic design, retaining walls, drainage, excavations and slopes, pavement sections, and utility support and trench backfill. It is anticipated that the City’s currently adopted erosion control, construction, and drainage regulations would adequately mitigate for any impacts that could result from the proposed development; therefore no further mitigation is recommended. Mitigation Measure: None recommended. Nexus: Not Applicable. 2. Water a. Storm Water Impacts: A Preliminary Technical Information Report (TIR) prepared by PacLand, dated May 2017 was submitted with the project application (Exhibit 3). The site falls within the Flow Control Duration Standard (matching forested site conditions). Runoff currently passes through an existing stormwater detention/treatment system, before entering the municipal stormwater system in 108th Avenue SE. After crossing over 108th Avenue SE and running underneath the Fred Meyer strip mall, across SE Carr Road, stormwater is discharged into Panther Creek. The project proposes to utilize a detention vault for storage and modular wetland system for water quality treatment. The proposed grading would direct water from the east side of the site toward the west side of the site. Stormwater would collect into catch basins along the east and south side of the building and be conveyed via pipe to the northwest corner of the site to the stormwater treatment structure. After treatment, stormwater would be directed to a detention vault, which would provide flow control before being released into the existing storm water system in 108 th Avenue SE. The sizing and design of the proposed flow control facility, water quality treatment facility, and on - site BMPs would be reviewed for compliance with the adopted 2017 City of Renton Surface Water Design Manual; therefore no further mitigation is recommended. Mitigation Measures: No further mitigation recommended. Nexus: Not applicable. 3. Transportation Impacts: A Traffic Analysis Report, prepared by Jake Traffic Engineering, Inc., dated May 2, 2017 was submitted with the project application (Exhibit 4). The submitted report concludes that the proposed redevelopment of the site from a fast food use to a dental office is anticipated to result in a net decrease of 1,020 net new daily trips. As the proposed project is anticipated to result in a net decrease in trips generated, a full traffic impact analysis is not required. The proposed project would be responsible for the construction of frontage improvements along 108th Avenue SE. It is anticipated that the construction of these improvements would adequately mitigate traffic generated by the project; therefore no further mitigation is recommended. City of Renton Department of Community & Economic Development Environmental Review Committee Report RENTON DENTAL ARTS LUA17-000289, ECF Report of June 26, 2017 Page 4 of 4 ERC Report_Renton Dental Arts Mitigation Measures: No further mitigation recommended.
