San Francisco’s new Fireboat Station No. 35 is a floating two-story, 16,000-square-foot building at Pier 22 ½ supported by a 173-foot-long by 96-foot-wide by 9-foot-deep steel float moored by four guide piles behind San Francisco’s historic Fire Station 35 building. The station includes a new steel pier and associated steel support piles adjacent to the Embarcadero and historic timber pier, a vehicular and pedestrian ramp between the steel pier and float that supports the building, and a gangway between the float and historic timber pier for the firefighters (Figures 1 and 2).
