A1: Main Avenue and Madrone Pipelines Restoration*

About This Project

As part of our commitment to continue providing reliable safe and clean water, Valley Water has completed construction relating to our work to restore the Main Avenue and Madrone pipelines. Approximately 14,000 linear feet (~2.6 miles) of 30-inch to 36-inch diameter raw water pipeline was installed to meet current and future groundwater recharge demand in Morgan Hill and south Santa Clara County.

With the completion of this project, the Main Avenue and Madrone pipelines are now capable of functioning at full operating capacity.  Together, these two pipelines can now convey local and imported raw water from Anderson Reservoir and the Santa Clara Conduit for groundwater recharge via the Main Avenue Recharge Ponds and the Madrone Channel. 

*This project was voter approved as part of the Safe, Clean Water and Natural Flood Protection Program.

History & Background

About the Safe, Clean Water and Natural Flood Protection Program

In November 2012 the voters of Santa Clara County overwhelmingly approved Measure B, the Safe, Clean Water and Natural Flood Protection Program, as a countywide special parcel tax for 15 years with a sunset date of June 30, 2028. This Program replaced the Clean, Safe Creeks and Natural Flood Protection Plan, which voters approved in November 2000.

The Safe, Clean Water Program was developed with input from more than 16,000 residents and stakeholders and was created to match the community’s needs and values. The voters of Santa Clara County identified five priorities:

Priority A: Ensure a Safe, Reliable Water Supply

Priority B: Reduce Toxins, Hazards and Contaminants in our Waterways

Priority C: Protect our Water Supply from Earthquakes and Natural Disasters

Priority D: Restore Wildlife Habitat and Provide Open Space

Priority E: Provide Flood Protection to Homes, Businesses, Schools and Highways

Other: Six projects from the Clean, Safe, Creeks Plan have been carried forward into the Safe, Clean Water Program.  

Each year, Valley Water prepares a report providing a progress update for each of these Program priorities, along with fiscal year accomplishments.

To ensure transparency and accountability to the voters, the ballot measure also created an Independent Monitoring Committee, appointed by the Santa Clara Valley Water District Board of Directors. The Independent Monitoring Committee annually reviews the Program’s progress to ensure the outcomes are achieved in a cost-efficient manner and reports its findings to the Board.

In addition, the Program requires three independent audits, the first of which was conducted in FY 2017.
