Beat Cops of the Bay

East Bay Express

How the nonprofit group Baykeeper monitors polluters in Bay Area waters... The greenish brown water laps at walls of concrete on each side of the estuary. On the west is the waterfront property of Manson Construction, a marine construction and dredging company that has stacked a paved site with cranes and shipping containers. Along the east side of the narrow inlet are Levin-Richmond Terminal, a Union Pacific coal depot, and Plains All American Pipeline, a Houston-based crude oil shipper. Together, these companies and several others have helped created a unique aesthetic in this remote corner of San Francisco Bay.
