Zone 2A Hydrology

Zone 2A was established in1965 to address occasional local flooding caused by overflows from the surrounding region. There are no natural creeks in this zone. Instead, stormwater is collected in underground pipelines in Zone 2A and delivered, via stormwater pipelines, to Zone 2. From there, flows are conveyed through the Estudillo Canal to the San Francisco Bay. grid
