The Waterfront Plan includes policies to restore, preserve and rehabilitate Port historic resources. Most of the piers, bulkhead buildings and waterfront structures along The Embarcadero built before World War II have been either listed on or determined eligible for listing on the National Register of Historic Places (National Register). National Register-listed historic resources are eligible for the Federal Historic Tax Credit Program. Through the Ferry Building and Pier 1 historic rehabilitation projects, the Port found that the tax credit benefits of this program (up to 20% of total development costs) are essential to realizing waterfront historic rehabilitation projects. (Embarcadero Historic District Nomination)
Separate from the resources in the Embarcadero Historic District, the Port's Pier 70 is endowed with the west coast's oldest collection of resources associated with the historic ship building, steel manufacturing and ship repair industries . These buildings and artifacts date from the 1850's through the heyday of the WWII ship building era, establishing an icon for the Port's Southern Waterfront, south of Mission Bay.
