Major wetland creation or restoration projects on the Pacific Coasts of the United States have regional characteristics and reasons for being built: (1) they are all either within deep bays or estuaries or the intertidal portion of a major river, (2) they all involve using dredge and fill activities, and (3) they are all intertidal herbaceous marshes (some with seagrasses at the lowest elevations). Projects are clustered in the San Francisco Bay and its major rivers, the lower Columbia river, and the Puget sound and its rivers, with infrequent large wetland projects in various stages of completion and long-term monitoring built from 1972 to the present: 8 in San Francisco Bay and the Sacramento river delta, 3 in the lower Columbia river, 2 in Puget sound, and 2 in southern California.
