Mission Bay Water Resources Projects,
San Francisco

​

BKF has worked on water resources elements on over 100 acres in Mission Bay. Recent highlights include pump stations 3 and 5 and the development of concept plans for Park Site 23 to show how treatment volume could be metered and pumped into bioswales and bioretention facilities to meet C.3 provisions. We also worked with the developer and City of San Francisco on a Storm Water Management Plan for the system. Additional work in Mission Bay includes:

• 9 submersible pumps
• Low Impact Design (LID)
• Shoreline & channel protection
• Trash capture

 

 

City of Mountain View Trash Capture

BKF coordinated with the trash device provider and the City of Mountain View to ensure a design that properly conveyed the expected hydrologic flows and caused the least disruption to the local neighborhood. BKF was responsible for the design of a hydrodynamic separator placed within a residential area. BKF determined the final placement of the device based upon the results of a utility analysis, gas lines, sewer lines, and overhead wires were in the immediate vicinity.

• Trash capture unit installation
• Hydrodynamic Separator
• City coordination

 

 

San Francisco Central Subway Sewer

​

Delta Coves Off-Site and Breach Water Lines, Bethel Island

​

Delta Coves is a 310-acre master-planned luxury waterfront community in the Sacramento-San Joaquin Delta area. Providing reliable water supply for drinking and fire suppression to the Delta Coves area on Bethel Island required innovative approaches to crossing sloughs and waterways to provide connections to the mainland.

• Design of 900 l.f. of 20” welded steel water pipe on Bethel Island Bridge
• Design of 6,500 l.f. of 18” DIP water pipe along Bethel Island Road

CPMC: Hospital, Van Ness/Geary Campus & MOB, San Francisco

Five separate roofs gardens will crown the Van Ness and Geary Campus. The green roofs will act as protection against stormwater runoff. Rainwater will be captured and used to drip-irrigate planting areas on the roof garden, saving 180,000 gallons of drinkable water per year that would otherwise be sent to the sewer and stormwater system. BKF prepared an analysis of existing demand and forecasted demands for water, wastewater, and solid waste.
