Item No.: 10a_Supp Meeting Date: September 28, 2021 West Seattle Bridges Memorandum of Understanding between the Port of Seattle and the City of Seattle Pearse Edwards, Senior Director, External Affairs | Lindsay Wolpa, NW Seaport Alliance September 28, 2021 Geraldine Poor, Regional Transportation | Sabrina Bolieu, Regional Government Relations 1 How We Got Here March 2020: Closure of the West Seattle High Bridge upon discovery of rapidly expanding cracks in the bridge infrastructure. November 2020: Mayor Durkan's decision to repair the high bridge, rather than replace with a new structure. March 2021: Mayor Durkan requested funding from federal and local governments to aid in the immediate repair and rehabilitation of the bridges. May 2021: City selected contractor for the final phase of repairs to safely reopen the bridge in mid-2022. 2 Why did the bridge fail? Post-tensioning strands are steel cables that tighten the bridge and strengthen the concrete Although designed to the standards of the time, insufficient post-tensioning caused the weight of the bridge (dead load) and the weight of traffic (live load) to be redistributed to parts not designed to carry these loads The center span has been stabilized. The tail spans have not Corridor-wide investment is needed to maintain reliability going forward 3 priorities during emergency closure: aggressive repair/rehabilitation to reopen; maintain mobility; mitigate detour routes Prioritizing Freight for Low Bridge Access Low bridge policy's economic growth and sustainability objective: Prioritize freight movement to support economic health and decrease detour route traffic Freight is a priority user along with emergency and transit vehicles All freight vehicles with gross vehicle weight of 10,001 pounds or higher can drive on the low bridge at any time Freight community members included on low bridge access subcommittee to help inform SDOT's decision on access Reconnect West Seattle To date, Reconnect West Seattle has built over 200 traffic mitigation projects, including: Improving traffic flow at Highland Park Way and West Marginal Way by creating additional turning and travel lanes Refreshing pavement markings and signs and improving signal timing along freight routes Adding 30,000 annual transit hours in West Seattle this October, plus extending the summer water taxi schedule through the winter Building 61 Home Zone projects to calm traffic speeds and enhance accessibility along detour routes through South Park, Georgetown, and Highland Park Current West Seattle Bridge Repair Status What we have done recently: Secured $37.7M in federal funding; grant legislation passed City Council on September 13 Approved by USDOT to use Community Workforce Agreement to hire workers from disadvantaged zip codes Maintained schedule for project permits Completed 60% design and modified scope of work Completed 90% design review Obtained approval to begin early work in advance of rehab West Seattle Bridges provide Regional Mobility West Seattle has one-sixth of the city's population and many small businesses. The High Bridge carried over 84,000 cars and trucks, along with 25,000 bus riders, every weekday prior to closure. The lower Swing Bridge carried over 10,000 trips per day, especially trucks serving the maritime and industrial businesses of the Duwamish MIC. Restoring the high bridge to full capacity will also remove traffic detours in place since the closure which: added 14-20 minutes to the typical resident's commute, separated businesses from customers, and impacted communities such as Georgetown and South Park. 7 Regional and statewide importance West Seattle Bridge is a critical point in region, state and the nation's transportation network Nearby terminals are key to our state's agriculture and maritime industries International cargo businesses headquartered nearby along with companies that serve as a lifeline for residents of Alaska and Hawaii Need to support large public investment in Terminal 5 made by The Northwest Seaport Alliance West Seattle Bridge Vicinity Map and Terminal 5 Terminal 5 West Seattle Bridge Closure 9 POS/NWSA Principles for West Seattle Bridges Improvements Program Low Bridge Freight Access Rapid Restoration Maritime Industry Access Equitable Implementation Strategic Economic Impact Sustainable Solutions Local Operations Support Broadly Supported Execution 10 Port Freight Mobility Investments Heavy Haul Network agreement Lander Memorandum of Agreement Safe & Swift Memorandum of (October 2015) (August 2016) Understanding (August 2017) Freight Master Plan (September 2016) and Puget Sound Gateway Program Interlocal Agreement Industrial Areas Freight Access Project (May 2015) between WSDOT / Port of Seattle (May 2020) 11 Low and high bridge structural rehabilitation construction schedules Note: Schedule and budget will be updated with more detail as we reach each project milestone. 12 Total Program Costs and Funding Strategy West Seattle Bridge Program Elements and Costs City Funding Strategy City of Seattle WEST SEATTLE BRIDGES PROGRAM Bonding City of Seattle $ 107,813,000 Reconnect West Seattle $ 49,994,731 STBD 8,000,000 Emergency Repairs 19,742,722 Gas Tax 4,840,000 Bridge Monitoring/Testing 3,360,344 Street Use & Occupation 730,000 High Bridge Repair 58,173,189 Commercial Parking Tax 217,000 Low Bridge Strengthening 13,297,000 General Funds/TNC 500,000 Low Bridge Control System / HDD and Comms 4,051,005 Federal Grants 39,150,600 High Bridge Replacement Planning 10,000,251 Port of Seattle 9,000,000 Traffic and Revenue Study 2,354,303 Program Development 14,276,672 Other Local Funds 5,000,000 Total: $175,250,217 Total: $ 175,250,600 13 Memorandum of Understanding Components Commit to Spokane Street Low Bridge access to Port properties, especially T-5 for freight, workers 2.4 and construction/maintenance Container Operations Include Port/NWSA needs in City's construction & traffic control planning to avoid or minimize 2.5 Nexus freight impacts 2.6 Support T-5 construction and permitting, especially emerging issues 2.7 Ensure freight mobility and support for industrial lands vitality Ensure the "Future Replacement Bridge" study protects container terminal functionality for 2030 2.8 Duwamish Sound Transit and 2060 W Seattle Bridges Transportation 2.9 Support street improvements for T-18 truck access (in design) Operations Interests Establish truck parking areas in the Duwamish MIC for benefit of both truck drivers and Duwamish 2.10 Valley residents Delay WMW bike lane decision until bridge reopens 2.11 Future bike lane design to maximize safety and minimize freight impacts Additional 2.12 Support East Marginal Way Improvements Phase 2 as priority for next Levy Interests Funding Three progressive payments upon completion of construction Strategy 14 Progress Payments FIRST PAYMENT OF SECOND PAYMENT OF THIRD AND FINAL $3,000,000 AFTER THE $3,000,000 AFTER THE PAYMENT $3,000,000: CITY HAS: CITY HAS: made upon Final reopened the High made upon Substantial Acceptance of all projects Bridge with full access Completion of the Spokane including progress on other consistent with prior St Swing Bridge Repair and MOU provisions operations (7 lanes) and Improvement Projects expected in 2023 shown progress on other including progress on other MOU provisions MOU provisions expected in mid-2022 expected by year end 2022 15 Questions? 16
