WATER WAYS MAP
This map shows how stormwater flows through our watershed. During a rain event, water makes its way from our streams and arroyos into these larger flood channels and rivers and eventually out to San Francisco Bay and the Pacific Ocean. It is important to remember that stormwater runoff also carries pollution through these waterways and out into the San Francisco Bay.
