BACKGROUND On February 15, 1966, a freeway maintenance agreement was executed between the County of Alameda and the State for the development of the portion of the state highway Interstate Route 580 (1-580) within the limits of the County of Alameda. In 1969, the City entered into a freeway maintenance agreement taking over the maintenance responsibility from the County which covered Hopyard Road. In August 1986, the City entered into an agreement with Caltrans for the construction of a northbound overcrossing structure at the Hopyard Road, Dougherty Road, and 1-580 interchange. On June 6, 1989, the City entered into an updated freeway maintenance agreement with Caltrans for 1-580 within the city limits. On September 6, 1994, the City entered into a cooperative agreement with Caltrans for the installation of highway plantings and an automatic irrigation system at the Hopyard Road and 1-580 interchange. On February 23, 2010, the City entered into an agreement with Caltrans for landscape maintenance within the state highway right of way on 1-580 for various locations, including Hopyard Road. DISCUSSION The City is working with Caltrans to obtain an encroachment permit for the Hopyard Road and Owens Drive Intersection Improvements Project, CIP No. 15525. The project proposes to construct a southbound right -turn lane along Hopyard Road at the Owens Drive intersection and to add a southbound bike lane to close the existing bike lane gap from the eastbound 1-580 off -ramp intersection to the south of Owens Drive. The project will include a new sound wall placed alongside the existing building'in the northwest quadrant of the intersection as the roadway is within 13 feet of the closest building. The proposed improvements within the State's right of way require the City to obtain an encroachment permit from Caltrans. As part of Caltrans' review and before issuance of an encroachment permit, Caltrans has required an update to the Freeway Maintenance Agreement for Hopyard Road and 1-580 bridge overcrossing. This includes updated mapping of the areas of ownership and documentation of responsibility. The attached project -specific maintenance agreement consolidates the previous agreements into one agreement and clarifies the responsibilities of both the State and the City concerning the roadway, bike path, bridge overcrossing, landscaped area, and sound wall maintenance for the Hopyard Road and 1-580 bridge overcrossing.
