Storm drain inlets are located around the campus and are usually located in and around parking lots, along the curbs of roads, and sometimes associated with runoff from the roofs of campus buildings. Storm water drain inlets located in the core campus drain directly into the Arboretum Waterway, and during the rainy season the excess water is pumped from the Arboretum Waterway to Putah Creek. Storm drains west of Hwy 113 and south of I-80 discharge directly to Putah Creek. Putah Creek flows to the Sacramento River, and ultimately to San Francisco Bay.
