Bollinger Road Bridge Reconstruction

Brief description:
This project was identified in the Clean, Safe Creeks and Natural Flood Protection Plan as an element of the first stage of the Calabazas Creek, Miller to Wardell, Flood Protection project. Overbanking occurred twice in 1998 and again in 2002. The district and the City of Cupertino partnered to rebuild the Bollinger Road bridge over Calabazas Creek.

The project had a completion ceremony Jan. 31, 2009 and is open for business. Full-width bicycle lanes are in place in both east and west bound directions. The old portion of the bridge which was not demolished has been reinforced for seismic safety. Revegation plantings, including three oak trees from higher up along the creek have been installed.

Project goals:
This joint project included the removal and replacement of the concrete box culvert that supports Bollinger Road bridge over the creek. The project objectives include: 

  • Provide capacity for the passage of 100-year storm flows
  • Uninterrupted bicycle and pedestrian facilities on Bollinger Road.
  • Improved wildlife passage throughout the length of the project.
  • Reinforcement of the existing bridge to meet current bridge structure standards.
  • Relocation of trees impacted by the project, and revegetation with native species.
  • Removal of the old, abandoned bridge upstream of the existing Bollinger Road bridge.
  • Support the separate Calabazas Creek Miller Avenue to Wardell Road flood protection project as outlined in the Clean Safe Creeks and Natural Flood Protection plan.
