Highlights of a self-guided day tour to six locations showing green infrastructure in San Francisco Bay.
The world’s seat of technology innovation, the San Francisco Bay region is teeming with creativity, energy and a hip plugged-in young workforce. The city’s population swells to 1.6 million people on workdays; just 900,000 live there. The East Bay, Berkeley and Oakland down to San Jose are home to Silicon Valley. During a recent trip to California, I spent a day touring to take a look at green infrastructure.
Like most large cities, San Francisco and other bay communities are using green infrastructure to control rainwater and to keep pollution out of San Francisco Bay. Stormwater management features also keep rainwater out of San Francisco’s aging combined sewer system that was constructed in the early 1950s. Even though California has been in the grip of severe drought for a number of years, during a 2013 presentation to Cities Alive in San Francisco, Emilio Cruz, Public Utilities Commission, said that from 2008 to 2013 the city experienced three 5-year storms. Over that time period the municipality also dealt with one 10-year storm and one 25-year storm. Handling the deluge of water from events like these in distributed stormwater management systems helps to keep surges of rainwater out of the city’s sewer treatment plant that’s already handling 775 million gallons of sewage a day. The Public Utilities Commission is spending $57 million on green infrastructure projects he said.
