Branham Lane to Blossom Hill Road (Reach 12)

The Santa Clara Valley Water District is working with the U.S.Army Corps of Engineers to restore habitat along the Guadalupe River from Branham Lane to Blossom Hill Road, a stretch known as Reach 12 of the Upper Guadalupe River Flood Protection Project.

This partnership is geared toward protecting more than 7,500 properties along s 5.7 mile stretch of the river from the effects of a 100-year flood. Such an event has a 1 percent chance of occurring in any given year.

Though Reach 12 has enough water carrying capacity and is not prone to major flooding, it has available land to create additional habitat along the river corridor that can offset the loss of habitat areas further downstream, where widening of the river for the overall flood protection project must occur.

Latest Updates

The water district and the Corps held a public meeting April 24 at the San Jose Public Library to present the project's design features and review the construction schedule. The meeting also informed the community about the area's vegetation plantings, instream wood structures and gravel placement for fish and location of maintenance roads.

The Corps has posted its environmental assessment of the project on its web page, which can be accessed by clicking here. The 30-day comment period runs through June 9, 2014, with comments to the Corps due on that date.

Project construction is slated to begin this fall and last about two years.
