On February 26, the Midpen Board of Directors voted to place a general obligation bond measure on the June 3, 2014 ballot. The decision came after a long public process to help shape the direction and priorities of the District into the future. The resulting vision plan reflects the public’s priorities to expand, enhance, and connect regional trails and open space areas, to preserve open space, and to complete restoration projects. 

This measure requires a two-thirds vote in Midpen’s jurisdiction in San Mateo and Santa Clara counties and a portion of unincorporated Santa Cruz County.

Based on public input and feedback, future bond money would:

  • Expand public access to protected land
  • Save local redwood forests
  • Provide clean air and water by restoring land that feeds our lakes, streams, ponds and waterways
  • Preserve agriculture along the San Mateo Coast
  • Restore native vegetation to create a healthy habitat for wildlife and preserve biodiversity.


An independent citizen oversight committee will review that funds are spent as promised.

Ballot Language
To improve access to hiking and biking opportunities, protect and preserve redwood forests, natural open spaces, the scenic beauty of our region and coastline, critical wildlife habitat, restore creeks to protect water quality, and reduce forest fire risk; shall Midpeninsula Regional Open Space District be authorized to issue up to $300 million in bonds, at a tax rate not to exceed $3.18 per $100,000 of assessed value of property owned, with expenditures verified by an independent citizen oversight committee?

Projects to be Funded by Measure AA
Through a public visioning process, Midpen staff and its Community Advisory Committee identified current and future project areas of high priority. These include adding trails and trail connections, opening new preserves, protecting redwood forests, preserving farmland, restoring wetlands and streams, providing habitat connectivity and reducing fire risk. The funding for this bond measure will be used toward the 25 highest priority projects.

About the District
Founded by voters in 1972, the Midpeninsula Regional Open Space District has protected 62,000 acres of open space in 26 preserves offering places for hiking, biking, horseback riding, or simply connecting with nature close to home and free of charge.
