Highways connect us, but also divide the land and create barriers to safe passage for both wildlife and people. In the Santa Cruz Mountains, California state route 17 (Highway 17) fragments thousands of acres of open space, limiting the ability of wildlife to find food, mates and habitat, as well as preventing the completion of several regional trail systems. Together with private and public partners, neighbors and District constituents, Midpen is exploring the feasibility of developing two independent road crossings - a wildlife undercrossing and recreational trail overcrossing - to link over 30,000 acres of protected public lands.
The project also includes directional fencing that will help animals safely find their way to the wildlife crossing and a number of regional trail connections that will link the following Santa Clara County parks and Midpen open space preserves together across Highway 17: Sanborn County Park, El Sereno Preserve, Lexington Reservoir County Park, St. Joseph's Hill Preserve, Sierra Azul Preserve and Almaden Quicksilver County Park.
Goals
- Link over 30,000 acres of habitat and protected public lands on both sides of Highway 17, including Midpen preserves (El Sereno, St Joseph's Hill and Sierra Azul) and Santa Clara County Parks (Lexington, Sanborn and Almaden Quicksilver)
- Improve motorist safety by reducing the potential for collisions with wildlife
- Maintain healthy wildlife populations
- Provide two structures - one for wildlife and one for recreational trail users - that support safe movement across Highway 17
- Connect over 50 miles of existing regional trails, including Bay Area Ridge Trail, Juan Bautista De Anza National Historic Trail and Los Gatos Creek Trail
- Develop a Mitigation Credit Agreement (MCA) to offset potential ecological impacts from construction with project benefits like habitat connectivity
Project components, colors, materials, etc. will be finalized during the design phase.)
Stay informed!
While wildlife and trail crossings share similar goals, animals and people have unique needs and use crossings in different ways. To meet the requirements of both, two distinct and separate structures have been recommended to cross Highway 17: a wildlife undercrossing and a trail overcrossing. The following locations for each crossing structure are currently under environmental review:
- a wildlife undercrossing at Trout Creek (2)
- a trail overcrossing either south of Trout Creek Canyon (southern overcrossing) or north of Trout Creek Canyon (northern overcrossing)
