ALAMEDA -- A proposal to build a ferry maintenance facility near the USS Hornet Museum at Alameda Point that could accommodate up to 12 vessels at a time will go before the San Francisco Bay Conservation and Development Commission on Monday.

Along with floating berths for ferries, the project proposed by the Water Emergency Transit Authority calls for a four-story building and a 13,500-square-foot yard, as well as an extension of the Bay Trail.

The project is going before the commission because part of the four-acre site at Ferry Point and West Hornet Avenue falls within its 100-foot jurisdiction of the bay shoreline.

Currently, about 25,000 square feet of dilapidated docks are within the city-owned site, which is bordered on the west by a pier used the U.S. Maritime Administration and on the east by a shoreline park.

The proposed 6,100-square-foot maintainenec building would be 70 feet tall and house engineering and other workshops, plus dispatch and administration offices for the transit authority, according to a background report prepared for the commission.

"A variety of activities would take place at the facility, including refueling ferries, bilge and sewer pump-out, fluid replenishment, repair and replacement of vessel equipment, trash disposal, cleaning and painting of vessels, storage and replenishment of concessionary items for passenger consumption," the report said.

The berthing facilities would include 14,452 square feet of floating docks and mooring facilities connected to a 500-square-foot pile-supported deck, which would lead to the yard and maintenance building.

There would be no public access because the facility must be fenced off for safety and security reasons.

"There is expected to be continual activity at the site and the work proposed for the yard and workshops requires handling hazardous and flammable materials," the report said.

The project also calls for new landscaping at the adjacent city-owned park and realigning and extending the Bay Trail 289 feet along West Hornet Avenue. Twelve trees would be planted, plus six benches would be installed along the shoreline.

Among the issues that the commission's design review board is expected to review Monday is whether the project will provide good public access to the shoreline and whether benches and other amenities for visitors could be improved.

The project comes as city officials are working to create a "town center" for the nearby area known as the Seaplane Lagoon. The waterfront neighborhood would include a ferry terminal and serve as a transit hub that would help link the area with the Webster Street Business District through West Atlantic Avenue.

The new neighborhood is expected to help jump-start redevelopment at the former military base, where city officials are considering building 1,425 homes and about 5.5 million square feet of commercial and business space.

Parks and trails, a waterfront promenade and a 44-acre sports complex near the Oakland-Alameda Estuary that would include ball fields and swimming pools are also proposed.

The city took ownership of about 1,400 acres of Alameda Point in June through a no-cost conveyance agreement with the Navy, which closed the base in 1997.

The agreement, the first phase of the base's overall transfer, provided the city with about 500 acres of land and nearly 900 acres beneath San Francisco Bay. The transfer is expected to be completed by 2019.
