BACKGROUND The City hired Otak to update our SWCP to provide a strategic framework for addressing drainage issues, water quality, erosion/sedimentation issues, habitat needs along with maintenance and condition assessment of the existing stormwater system. It further serves as a guidebook for City staff to define and build upon for capital projects, work programs, and strategies for meeting existing and future surface water management needs. This plan was last updated in 2013. DISCUSSION The SWCP includes programmatic solutions and policies, studies, and future capital projects. These recommendations were developed by reviewing past project lists, interviewing staff, conducting field assessments and public outreach. Past projects that are no longer needed are removed, existing project costs are updated, and new projects are added to address deficiencies and goals. A total of 11 individual capital projects, 5 capital improvement programs, and 3 studies are being proposed in the SWCP utilizing the 412 Surface Water fund: • Norfolk Outfall Trunkline Sewer Separation Preliminary Feasibility Study • Tukwila Pond Stormwater Quality Improvement • Fort Dent Park Water Quality Retrofit • Tukwila Parkway / Gilliam Creek Outfalls Stormwater Improvement (updated) • Johnson Creek Fish Barrier Mitigation Alternatives Analysis • S Ryan Way Pipe Rehabilitation • Fish Passage Barrier Prioritization Study • Middle Fork of Southgate Creek — Stream and Slope Stability Study • P17 Pond and Southcenter Subarea Hydraulic Study • Stormwater Management Action Plan (SMAP) Programmatic CIP • Ecosystem Services Conservation Program RECOMMENDATION Requesting to forward the final 2024 SWCP for adoption at the June 17th Council meeting.

Edquid Page 2 of 2 116 City of Tukwila 2024 Surface Water Comprehensive Plan Executive Summary This 2024 Surface Water Comprehensive Plan (SWCP) is an update to the SWCP prepared in 2013, available here: https://www.tukwilawa.gov/wp-content/uploads/PW-Surface-Water- Comprehensive-Plan.pdf. The purpose of this Surface Water Comprehensive Plan is to provide a strategic framework for the management of surface water within the City of Tukwila. The 2024 SWCP strives to have a multi -benefit approach to surface water management by: • Protecting the public's health and safety • Protecting public property, private property, and roads from localized flooding from stormwater drainage • Conserving and enhancing the natural aquatic systems within the City • Restoring salmon habitat and improving access to salmon habitat • Coordinating with regional surface water plans and projects • Having a clear understanding of the existing stormwater system • Maintaining compliance with local, state, and federal regulations related to surface water The recommendations outlined in the 2024 SWCP consist of programmatic solutions and policies, studies, and capital projects. Not all capital improvement projects (CIPs) are recommended for implementation in this surface water planning window, due to funding availability. The tables below outline the recommendations by priority. Table Ex-1 High Priority Capital and Programmatic Recommendations Recommendation Reason Implementation In -progress Surface Water CIPs identified in the City's 2023-2028 Capital Improvement Program Ongoing Prior years — 2025 or beyond Programmatic changes pursuant to 2024-2029 NPDES Phase II permit requirements - TBD Maintain regulatory compliance 2025-2029 117 Recommendation Reason Implementation CIP-1 Norfolk Outfall Trunkline Sewer Separation Preliminary Feasibility Study Reduce potential City liability for combined sewer overflows and responsibility for Superfund site cleanup 2025 CIP 91241202 Stormwater Outfalls Water Quality Retrofit Program Grant award received; meets regional priorities for reducing harmful effects of urban runoff on water bodies; completes programmatic CIP begun in 2017 2024 CIP 99441202 Soil Reclamation Facility / Enhanced Maintenance Program and Decant Facility Design — Part 1 Grant award received; supports NPDES Phase II permit requirements; meets regional priorities for reducing harmful effects of urban runoff 2024-2025 Stormwater Management Action Program (SMAP) CIPs Meets expected requirement of 2024- 2029 NPDES Phase II permit; meets regional priorities for reducing harmful effects of urban runoff on water bodies; eligible for grant funding Begin 2025, then ongoing every 2-3 years WSDOT Retrofit Program Required in order to charge surface water management fee to WSDOT; meets regional priorities for reducing harmful effects of urban runoff on water bodies; funded by WSDOT 2024 and annually CIP-102 Middle Fork Southgate Creek — Stream and Slope Stability Study Stream condition severely degraded and private property at risk. Coordinates with ongoing Southgate Hydraulic Study encompassing Normed Facility and could make use of findings from City's successful FEMA- funded landslide study. 2026 CIP-3 Fort Dent Park Water Quality Retrofit, Alternative 1 Meets regional priorities for reducing harmful effects of urban runoff on water bodies; low-cost alternative that can be implemented by City crews. 2027 CIP-2 S Ryan Way Pipe Rehabilitation Collaboration with City Transportation Department; preventive repair and replacement; reduce sheet flow on steep high -traffic roadway Coordinate timing with City Transportation Department 118 Recommendation Reason Implementation MS4 mapping and documentation programmatic recommendations City risks permit non-compliance. Barriers to information sharing hinders stormwater planning, regulatory review of development and construction, inspection and enforcement, and capital project development. 2025-2029 Apply for grant funding for eligible phases of programmatic water quality CIPs and medium priority projects identified below Allows City to continue to fund higher levels of capital investments without impacting surface water utility rates 2024-2034 Ecosystem Services Conservation Program Reduces disparities in access to healthy environments, improves interdepartmental coordination in working on regional priorities such as reducing harmful effects of urban runoff, increasing access to fish habitat, and increasing quality of fish habitat Begin 2025 Regulatory and Policy change - omit the current regulatory enforcement procedure which permits temporary gravel parking lots to be constructed without stormwater drainage and runoff treatment facilities and then effectively to become permanent untreated impervious surfaces. City risks permit non-compliance. Strategically time interdepartmental negotiations and policy -setting with reissuance of NPDES Phase II permit in 2024. 2025 Table Ex-2 Medium Priority Capital and Programmatic Recommendations Recommendation Reason Implementation CIP 98641222 S 143rd St Storm Drain System Longstanding drainage / flooding issue which may be eligible for grant funding from KCFCD 2027 CIP 99441202 Soil Reclamation Facility / Enhanced Maintenance Program and Decant Facility Design — Part 2 Increase efficiency and effectiveness of operations and maintenance program 2026 CIP 98741202 Nelson/Longacres — Phase II Longstanding drainage / flooding issue which requires coordination with railroad and may be eligible for grant funding from KCFCD 2028 119 Recommendation Reason Implementation CIP-6 Johnson Creek Fish Barrier Mitigation Alternatives Analysis Meets regional priorities to increase access to fish habitat; ensures balanced portfolio of CIP projects by including fish barrier removals at regular intervals 2026 CIP-90341214 S 146th St and 35th Ave S Drainage Longstanding drainage / flooding issue which may be eligible for grant funding from KCFCD 2029 The 2024 SWCP proves a strategic framework for the management of surface water within the City of Tukwila. It is an ambitious proposal for tackling drainage issues, water quality, erosion/sedimentation issues, habitat loss, and maintenance and condition of the stormwater system. The 2024 SWCP recognizes that City of Tukwila can be a key partner with state agencies, King County, Tribes, and organizations in reaching toward regional priorities to protect and restore the region's cherished natural resources. The City of Tukwila Public Works Department asserts that the 2024 Surface Water Comprehensive Plan would not have significant adverse impacts on the environment.
