Inventory of coastal engineering projects in San Francisco Maritime National Historical Park
Dallas K, Berry M, Reggiero P. 2013. Inventory of coastal engineering projects in San Francisco Maritime National Historical Park. Natural Resource Technical Report. NPS/NRSS/GRD/NRTR—2013/735. National Park Service. Fort Collins, Colorado
This report includes information on coastal engineering projects identified in, or immediately adjacent to, San Francisco Maritime National Historical Park (SAFR). The report serves as a supplement to a Geographic Information Systems (GIS) database (the GIS data are available online at http://irma.nps.gov). Twelve coastal engineering projects were identified within SAFR. Of these, nine are coastal structures that span 2,275 m (7,465 ft) (this includes 324 m [1,063 ft] of a breakwater that is outside SAFR). The Aquatic Park Seawall armors roughly 88% of the total shoreline within the park. Aquatic Park Cove was filled with an unknown volume of material from 1906–1914 and again in the 1930s. In 1941, 2.3 million m3 (3 million yd3) of sand was placed along the beach. Coastal engineering projects have greatly altered the physical landscape and ecosystem in and adjacent to SAFR. Historic filling operations have transformed the once low-lying marshlands into a prime recreational venue by extending the shoreline roughly 120 m (400 ft) since the mid-1800s. Filling, coupled with shoreline armoring and nourishment activities, has altered local wave and circulation patterns, sediment dynamics, and the natural ecosystem.
