The Santa Clara Valley Urban Runoff Pollution Program is an association of thirteen cities and towns in the Santa Clara Valley, together with Santa Clara County and the Santa Clara Valley Water District. The program participants share a common National Pollutant Discharge Elimination System permit to discharge storm water to the San Francisco Bay.
To reduce pollution in urban runoff to the "maximum" extent possible, the program incorporates regulatory, monitoring and outreach measures aimed at improving the water quality of San Francisco Bay and local creeks.
All storm drains in Los Altos drain directly to local creeks and the Bay. Discharge from storm drains is not treated. Pollutants enter our environment when they are poured directly into storm drains or rinsed into the storm drain system by rainfall or wash discharges. Storm drain systems are a major source of pollution in San Francisco Bay.
