The area in the 19th century prior to the 1906 earthquake consisted of bay shallows , tidal pools , sand dunes , and marshland similar to nearby Crissy Field . Human habitation and development came in the mid to late 19th century in the form of a sandwall and of a road from the nearby Presidio to Fort Mason . Most of the sand dunes were leveled out and a hodgepodge of wharves and industrial plants was built extending from what is now Laguna Street to Steiner Street . However , all of this was destroyed in the 1906 earthquake
