DEPARTMENT OF COMMUNITY & ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: 09/24/2020 TO: Jill Ding, Senior Planner FROM: Michael Sippo, Civil Engineer III, Plan Review SUBJECT: Gene Coulon Memorial Beach Park Trestle Bridge Replacement 1201 Lake Washington BLVD N PRE20-000203 NOTE: The applicant is cautioned that information contained in this summary is preliminary and non-binding and may be subject to modification and/or concurrence by official City decision- makers. Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. I have completed a preliminary review for the above-referenced proposal located at parcel(s) 052305-9010 and 334450-0775. The purpose of the project is to replace an existing timber trestle with a new single-span steel bridge, that includes concrete abutments, and grated decking (see Site Plans, Sheets 1 through 5). The project site is located in Gene Coulon Memorial Beach Park in Renton, Washington. A condition assessment of the existing timber trestle, performed in 2017, found deterioration and timber trestle repairs were required. During the repairs of the timber trestle in 2018, additional timber piles were observed to have severe deterioration. With approximately 40% of the piles requiring replacement it was determined that the existing timber trestle required replacement with a new bridge. The new bridge will be a single-span steel bridge with pile supported concrete abutments. This new bridge is designed to accommodate park maintenance vehicles, which is consistent with the existing bridges current use, and conforms to the Americans with Disabilities Act accessibility guidelines. The new steel bridge will be conducted primarily within the existing bridge footprint and will have less overwater coverage. This project will result in the removal of 58 creosote treated piles and the replacement of 899 square-feet of Gene Coulon Memorial Beach Park Trestle Bridge Replacement – PRE20-000203 Error!

DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: September 24, 2020 TO: Pre-Application File No. 20-000203 FROM: Jill Ding, Senior Planner SUBJECT: Gene Coulon Memorial Beach Park Trestle Replacement 1201 Lake Washington Blvd N (Parcel No. 3344500775) General: We have completed a preliminary review of the pre-application for the above-referenced development proposal. The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant and the codes in effect on the date of review. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision-makers (e.g., Hearing Examiner, Community & Economic Development Administrator, Public Works Administrator, Planning Director, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. The Development Regulations are available online at https://www.codepublishing.com/WA/Renton/. Project Proposal: The City of Renton Parks Planning & Natural Resources Division proposes replacement of an existing timber trestle pedestrian bridge over Lake Washington within Gene Coulon Memorial Beach Park (Park) in Renton, Washington. The existing pedestrian timber trestle is comprised of timber abutments, timber decking, pedestrian handrails, and timber piles. A condition assessment of the timber trestle in 2017 found deterioration and timber trestle repairs were required. During 2018 repairs of the timber trestle, additional timber piles were observed to have severe deterioration. With approximately 40% of the piles requiring replacement it was determined that the existing timber trestle bridge required replacement with a new single-span steel bridge, that includes concrete abutments, and grated decking. The proposed actions will involve work below the ordinary high- water mark (OHWM) of Lake Washington. The USACE will serve as the lead agency in this consultation. The project site is surrounded by Lake Washington, a Shoreline of the State, and is within reach F and the Shoreline Urban Conservancy designation. There are two Category IV wetland mapped in the project vicinity. Current Use: An existing bridge is located on the project site, proposed for replacement. Comprehensive Land Use Plan and Zoning: The project site is located in Gene Coulon Memorial Beach Park, a regional park with a zoning designation of Residential 1 (R-1) and a Comprehensive Plan designation of Residential Low Density. Development Standards: There are no specific building or site development standards applicable to the proposed trestle bridge replacement, with the exception of the Shoreline regulations, RMC 4-3-090. Coulon Park Memorial Beach Trestle Bridge Replacement Page 2 of 2 September 24, 2020 Critical Areas: The site is located within 200 feet of Lake Washington, a Shoreline of the State. The shoreline designation at this location is Shoreline Urban Conservancy and the reach is Lake Washington Reach F. Two Category IV wetlands have been identified within the project vicinity. Category IV wetlands required a standard buffer of 50 feet with a 15-foot building setback. A wetland report and mitigation plan in compliance shall be submitted at the time of formal land use application, if impacts to associated wetlands and/or buffer areas are proposed. The submitted wetland and stream report should include an analysis regarding whether the proposed bridge replacement would result in a net loss of ecological functions and values. Shoreline Master Program: The Shoreline Master Program requires a 100-foot setback from the edge of the Ordinary High Water Mark (OHWM). Maintenance of existing trails and recreational uses are allowed within the 100-foot shoreline setback. All existing trails can be replaced in kind as maintenance and repair. However, if any portion of the existing trail is expanding the new trail or expanded portions would be required to comply with current shoreline master program regulations and the partial compliance table for non-single family development pursuant to RMC 4- 10-095. Environmental Review: The proposal is exempt from State Environmental Policy Act (SEPA) review, as the proposal includes maintenance and repair of an existing structure. Permit Requirements: The proposal would require a Shoreline Substantial Development Permit Exemption and a critical areas exemption. There are no fees associated with these applications. Note: When the formal application materials are complete, the applicant is strongly encouraged to have the application materials pre-screened prior to submitting the complete application package.
