E4: Upper Penitencia Creek Flood Protection

Preferred project: A federal-state-local partnership

This project continues a partnership with the U.S. Army Corps of Engineers (USACE) to plan, design and construct improvements along 4.2 miles of Upper Penitencia Creek from the confluence with Coyote Creek to Dorel Drive. The project is also funded in partnership with the state. Part of the project must be completed prior to a planned Silicon Valley Rapid Transit extension to the Bay Area Rapid Transit line, to protect the area around the proposed Berryessa station near King Road, which would otherwise be subject to flooding.

The natural creek channel will be preserved while adjacent existing open space and parkland will remain as recreational areas, only rarely taking the role as a temporary floodplain so that floodwaters do not enter surrounding neighborhoods and commercial areas. Proposed construction measures may include modified floodplains, levees, flood walls, bypass channels, and fish passage improvements. Existing District water supply facilities may also be modified to protect habitat and improve water supply reliability.

The $41.9 million in local funding from Safe, Clean Water allows the District to move ahead with the planning, design and construction of the project. 


Benefits

  • Preferred project provides 1% flood protection to approximately 5,000 homes, schools and businesses. Locally-funded-only project provides 1% flood protection to the proposed rapid transit station and areas downstream from King Road.
  • Reduces sedimentation and maintenance requirements
  • Improves water quality in Coyote Creek
  • Provides opportunities for recreation improvements consistent with the City of San Jose and Santa Clara County Park master plans


Project Status

(As of June 2017)
