southbound I-880 in San Leandro. The $108 million HOV lane project will extend the southbound HOV lane from approximately Hegenberger Road to just south of Marina Boulevard. The HOV lane project will require the reconstruction of both the Davis Street and Marina Boulevard overcrossings. To minimize the disruption of traffic and inconvenience to San Leandro residents, staff recommends that the improvements to the Marina Boulevard Interchange be coordinated with the design and construction of the southbound HOV lane on I-880, which will be managed by the ACCMA. The ACCMA, the Alameda County Transportation Improvement Authority (ACTIA), Alameda County (County), the City of Hayward and the City of San Leandro are currently completing a study to identify and prioritize improvements for I-880 in central Alameda County. The I- 880/Marina Boulevard Interchange project is one of the projects being reviewed in the study. The study preliminarily estimated the design and construction cost for the interchange at $33 million. Staff has reviewed and refined this preliminary cost estimate to $27 million. Analysis The Proposition 1B HOV lane project requires the reconstruction of the overcrossing, but does not provide for the improvements to the interchange. The improvements to the interchange, which include on-ramp and off-ran~p improvements, lane configuration changes, traffic signals and other associated features, are necessary to accommodate fiiture development in the area. Funding to complete these improvements will come from several sources, including the general public as it is also responsible for a fair share of the cost. The public's share of cost for the constniction of the interchange improvements will most likely come from the Local Alternative Transportation Improvement Program (LATIP), the State Transportation Improvement Program (STIP) and from local funds composed of special impact fees and Measure B funds. It should be noted that the LATIP funds are available as a result of the deletion of the Route 238 Hayward Bypass project from the Measure B expenditure plan. Funding for the HOV lane project is being primarily financed by the Corridor Mobility Improvement Program of the recently approved State Infrastructure Bond Program (Proposition 1B). However, the HOV lane project requires additional support from the County and benefiting local jurisdictions. The ability to acquire the needed funds in advance allows not only for the completion of the HOV project, but also for the addition of the design and construction of the interchange improvements. The ACCMA and the City recognize that there are inherent benefits to coordinating the HOV lane and interchange projects. Doing so allows for a robust funding plan that will efficiently use and leverage funding as it becomes available. It will also allow greater coordination of the environmental review, design and construction; thereby providing economies of scale for a reduced overall project cost. This MOU is being prepared to detail the understandings between the City and ACCMA. The MOU acknowledges that it is in the best interest of the residents of the County that both the interchange and the HOV lane projects be coordinated to provide an integrated transportation facility that efficiently uses and leverages fm~ding resources to improve traffic conditions. The City Council has recently authorized the City Manager to enter into a Memorandum of Understanding between the City and Kaiser. Kaiser has offered to forward its fair share for the construction of the interchange in advance of receiving the entitlements far the Medical-Retail Complex. Kaiser has made this offer to facilitate the completion of the interchange in
