BACKGROUND: Transportation Authority of Marin (TAM) staff will be present to provide an update on the Northbound US 101 to Eastbound I-580 Director Connector project, now referred to as the “US 101/I- 580 Multimodal and Local Access Improvement Project.” This verbal update will include a I-580 interchange Proof of Concept analysis that was completed earlier this year. The non-profit Resilient Shore approached the Transportation Authority of Marin (TAM) with a proposed interchange concept on I-580 between Bellam Boulevard and the Richmond-San Rafael (RSR) Bridge. Resilient Shore stated that the purpose of this new interchange would be to provide additional access to I-580 for the Canal Neighborhood and East San Rafael, relieve traffic congestion on Bellam Boulevard, provide an additional connection to Andersen Drive and areas south of I-580, and provide an additional evacuation route in an emergency scenario such as a flood event exacerbated by sea level rise. TAM performed a Proof of Concept analysis for the proposed interchange concept and will present the results of the study including potential right of way, environmental and visual impacts, likelihood of approval by Caltrans and Federal Highway Administration (FHWA) and estimate of cost. The study does not include a detailed traffic analysis or an evaluation of different interchange alternatives but includes an assessment of various challenges and issues that would need to be overcome to support a new interchange along I-580 in San Rafael, regardless of the type of interchange. In addition, a City of San Rafael future land use analysis and traffic demand forecast for East San Rafael would have to demonstrate a need for a new interchange before initiating any further analysis of interchange options. The City has submitted a One Bay Area Grant (OBAG 3) planning application for the Priority Development Area (PDA) for the Canal neighborhood to create a precise plan. The PDA would include evaluation of SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 2 housing opportunities, access and infrastructure projects which could include a discussion on an overcrossing or interchange. COMMUNITY OUTREACH: TAM has a dedicated webpage for this project, which includes a section on community engagement. FISCAL IMPACT: There is no direct fiscal impact associated with accepting the report. RECOMMENDATION: Accept the Report.
