E8: Upper Guadalupe River Flood Protection. Highway 280 to Blossom Hill Road—San Jose

Preferred project: A federal-state-local partnership

This federally authorized project continues a Clean, Safe Creeks project partnership with the U.S. Army Corps of Engineers (USACE) to plan, design and construct improvements along 5.5 miles of channel extending from Interstate 280 to Blossom Hill Road. Improvements include channel widening, construction of floodwalls and levees, replacement of road crossings and planting of streamside vegetation. Reducing flood frequency and bank erosion will improve water quality, while planned mitigation measures will give fish access to an additional 12 miles of habitat within and upstream of the project reach.


  • Preferred project will construct 1% (or 100-year) flood conveyance capacity for 5.5 miles of channel in San Jose, protecting approximately 6,280 homes, 320 businesses and 10 schools/institutions
  • Local funding only constructs improvements to 4,100 linear feet to convey 1% flow
  • Improves stream habitat values and fisheries
  • Improves stream water quality
  • Allows for creek side trail access

Project Status

(As of September 2017)

  1. USACE plans to complete the mitigation planting for Reach 12 under a separate contract in 2016.
  2. USACE expects to complete the 100% bridge design for the vehicular bridge at Willow Street by December, 2017.
  3. Construction of Willow Street bridge is scheduled for Summer 2018. 
  4. The 100% design for the bypass channel in Reaches 7 and 8, Alma Bridge, and two railraod bridges is expected to be completed by December, 2018. 
  5. The USACE accepted the Betterment request for the replacement of 2 railroad bridges in Reaches 7.
  6. District continues acquiring rights of way for the project.

Key Performance Indicators

  1. Preferred project with federal and local funding: Construct a flood protection project to provide 1% flood protection to 6,280 homes, 320 businesses and 10 schools and institutions

  2. With local funding only: Construct flood protection improvements along 4,100 feet of Guadalupe River between the Southern Pacific Railroad (SPRR) crossing downstream of Willow Street to the Union Pacific Railroad (UPRR) crossing downstream of Padres Drive. Flood damage will be reduced; however, protection from the 1% flood is not provided until completion of the entire Upper Guadalupe River Project
