The U.S. Army Corps of Engineers and the Santa Clara Valley Water District held a community meeting on Sept. 12, 2016. Construction work along Upper Berryessa Creek stretching from Calaveras Boulevard to I-680 breaks ground this fall. At the pre-construction meeting, staff from both agencies shared information on what to expect during construction, the project schedule, and how to contact us during work activities. Staff addressed concerns and questions at this meeting.
Please contact your neighborhood liason Ed Morales by email if you have any questions.
About the project
The Upper Berryessa Creek flood protection project offers a tremendous opportunity for a project to increase flood protection and stabilize the channel banks The water district will continue to work with the community and cities to provide critical flood protection needs for Milpitas and San Jose.
The Berryessa Creek Flood Risk Management Project (fact sheet) encompasses approximately 2.2 miles of Berryessa Creek from Calaveras Boulevard to Interstate 680.
Upper Berryessa Creek has a history of flooding, having experienced major events within the project area in 1982, 1983, and 1998. In 1982, the bank overflowed south of Calaveras Boulevard. To date, the creek has a 25 percent chance of flooding each year.
Flooding can result in millions of dollars in damage to homes, businesses, schools, and other infrastructure. Disruption to businesses and transportation networks such as the upcoming BART station at Montague Expressway will result in significant loss of productivity and revenue. One of the project’s goals is to avoid utility and transportation shutdowns and prevent potential damages from a 100-year storm event* exceeding $528 million (2011 value) per event. Approximately, 500 businesses and homes would be affected. The Santa Clara Valley Water District has initiated design of a flood protection project along 2.2 miles of the creek from Calaveras Boulevard to Interstate 680.
* A 100-year storm event, sometimes called a one-percent flood event, has a 1-in-100 chance of occuring in any given year.
By the numbers
The Safe, Clean Water and Natural Flood Protection Program provides funds to design and construct a project to:
Provide flood protection in the cities of Milpitas and San Jose from Interstate 680 to Calaveras Boulevard and for more than 30 miles of streets including Highway 237 and Montague Expressway
Protect 650 parcels from a 100-year flood event
Provide long-term benefits to stream ecology and environmental habitat
Minimize project impacts to the environment
- Identify environmental enhancement opportunities
- Reduce erosion, sedimentation, maintenance requirements, and improve water quality
Prevent potential damages in excess of $528 million (2011 value) from a 100-year flood event
The project will include planting of over 100 native trees and shrubs and hydroseeding native wetlands plants to improve the environment and visual quality of the area
The project is funded by the countywide Safe, Clean Water and Natural Flood Protection Program parcel tax passed by voters in November 2012. The 15-year plan makes it possible to protect homes, schools and businesses from flooding, while improving the health of creek and bay ecosystems and creating trails and parks for recreational enjoyment.
The Upper Berryessa Creek flood protection project offers a tremendous opportunity for a multi-purpose project to increase flood protection, create recreational opportunities and improve the environment. The water district will continue to work with the community and cities to provide critical flood protection needs for Milpitas and San Jose.
Construction is planned for September 2016 through December 2017 to provide flood protection for the newly constructed BART Milpitas Station which is expected to open in late 2017.
