Environmental & Community Benefits

The Santa Clara Valley Water District's Berryessa Creek Flood Protection Project, when completed, will protect 2,447 parcels in Milpitas from the threat of a 100-year flood event, which has a 1-in-100 chance of occurring in any given year. The Berryessa Creek Flood Protection Project includes both the Upper Berryessa Creek portion and the Lower Berryessa Creek portion.

The Lower Berryessa Creek portion of the project, which includes Calera and Tularcitos creeks, will protect 1,823 properties in Milpitas, between Milpitas High School and E. Calaveras Boulevard (north to south) and the Union Pacific Railroad to Highway 680 (east to west).

History & Background

The Lower Berryessa Creek Flood Protection Project extends approximately 1.7 miles through the city of Milpitas, from its confluence with Lower Penitencia Creek, south to Caleveras Boulevard. The project also includes about 2.1 miles of Calera and Tularcitos creeks. These two smaller creeks are tributaries to Berryessa Creek and must also be modified to prevent water from overflowing their banks. When complete, this project will protect vast portions of the City of Milpitas from flood events. 

Phase 1 (yellow area on the map)
This phase stretches from the confluence at Lower Penitencia Creek (approximately 400 feet south of Milmont Drive Bridge) to Abel Street. The flood protection improvements for this phase include earthen levees on the east side of the creek and artificial floodwalls on the west side of the creek, as well as an enhanced tidal and freshwater wetlands area. Construction of Phase 1 was completed in December 2016. Plant establishment work will continue through December 2021.
