The work will be performed approximately 80 feet from the ordinary high water mark (OWMH) of the Cedar River (see attached Site Plan). The project site is located in the Residential Conservation (RC) zoning district and is part of the Cedar River Natural Area. The 160.6 acre site is located within a High Seismic Hazard Area, Moderate Landslide Hazard, Moderate Coalmine Hazard, High Erosion Hazard, Wellhead Protection Area Zone 1, and the High Intensity Regulated Shoreline Overlay within Reach C of the Cedar River (CR-C). The borings are necessary for research and site investigative work to support the re-establishment of a section of the Cedar River Trail that was damaged during a heavy rain event in the spring of 2021. After the rain event, City staff discovered the sloped bank adjacent to the trail had substantially eroded, undermining the stability of the asphalt trail and creating a potential safety issue for trail users. The results of the exploratory geotechnical boring would be used by the City and consultant to develop a slope stabilization plan for the adjacent bank between the trail and the river. All proposed work would occur landward of the OHWM within the path of the existing trail. Access to the boring location will be from the Cedar River Dog Park and trailhead parking to the site. To facilitate the drilling, the applicant DocuSign Envelope ID: 1D4DDFA2-648B-4C6E-AE26-7F036E2E243A City of Renton Department of Community & Economic Development Certificate of Exemption From Shoreline Substantial Cedar River Bank Stabilization Geo-Borings, LUA21-000216, SME, CAE Development Permit and Critical Areas Regulations Permit Date: June 17, 2021 Page 2 of 4 D_Shoreline Exemption_Cedar River Trail Stabilization_210611_v2_F has proposed cutting a 12-inch diameter core in the trail pavement. The single boring will be collected using a hollow stem auger driven to a depth of approximately 60 feet. Soil samples will be collected at regular intervals as the drill progresses to lower depths. Temporary erosion control measures will be established around the perimeter of the work area to ensure limited impacts to surrounding vegetation. Debris generated during drilling will be collected and transported off-site for disposal and the boring hole will be backfilled per Department of Ecology guidelines. A cold mix asphalt patch will be used to restore the trail surface. No structures will be constructed as part of the project and all work will be limited to subsurface exploration which is not anticipated to affect the aesthetic quality of the area. No vegetation or trees is proposed for removal, although minor disturbance in the immediate area of the trail is possible. The project is anticipated to result in a temporary one-day trail closure to be implemented by City of Renton Department Community Services Department. The drilling is anticipated to be completed on June 22, 2021.
