Why was Schoolhouse Creek filled?
assistant
Schoolhouse Creek was filled because it was considered a nuisance. The marsh was filled, the creek was channeled into a pipe that also carried sewage to the Bay, and the shoreline was extended westward with Berkeley's garbage. East Bay Municipal District intercepted the sewage in the late 1940s, but the creek still flows in the pipe just north of and parallel to Virginia Street, reaching San Francisco Bay in the squared off "North Basin" that was destined to be filled by more garbage, before citizen effort halted Bay fill in the 1960s
