A 1,200 square foot green roof was constructed atop the Summit Pump Station in central San Francisco, as part of an upgrade of the pump station facility.  Impetus for the green roof was primarily aesthetic, because the facility roof is visible from the surrounding hills, and also hydrologic, to provide low-impact stormwater management, also called Low Impact Development (LID).

The Summit Pump Station is located north of Olympia Way at Delbrook Avenue, in central San Francisco near the Sutro Tower.  It was originally constructed in 1953, to pump potable water uphill to higher elevation residences and businesses.  Having exceeded its useful life and no longer meeting building and seismic codes, it was replaced in 2006-2007 with an entirely new facility. As part of the upgrade, a green roof was installed atop the pump station building.
