Glen Canyon Trails Improvement Project

VIDEO OF COMPLETED GRANT-FUNDED SADDLE AREA TRAIL IMPROVEMENTS!

DESCRIPTION

Beyond Glen Canyon Park’s recreation center, ball field, and tennis courts lies a large urban canyon that has incredible spring wildflower displays, dramatic rock (chert) formations, and Islais Creek, one of the few remaining free-flowing creeks in San Francisco. This 60 acres of wilderness, formerly referred to as the San Miguel Hills, not only provides critical habitat for a wide array of wildlife, but serves as a relaxing sanctuary from the city’s urban bustle. An extensive network of hiking trails leads through a variety of habitats, from the lush creekside vegetation to the rocky grass- and scrublands of the canyon’s steep eastern slope, where a profusion of wildflowers blooms each spring.

SCOPE OF WORK

The Glen Canyon Trail Restoration project will repair existing trails and steps, provide fencing for public safety and to protect sensitive habitat areas, provide erosion control measures, restore native plants and provide wayfinding signage. The existing trails are in poor condition and in need of restoration. The proposed trail restoration will improve safety, repair retaining edges, address seeps and wet areas to improve pedestrian access, address invasive plant and hazardous tree removal, and enhance the trail experience in Glen Canyon Park by retaining the rustic quality of the trail.

Project FAQs

CREEKSIDE LOOP TRAIL

Glen Canyon's Creekside Loop Trail is a multi-use trail that allows visitors to enjoy views of Islais Creek, one of the last free-flowing creeks in San Francisco. To better serve park users and improve safety, the Urban Trails Program will widen and stabilize sections of the trail that are narrow and highly erosive and install attractive rustic fences in areas that are steep and dangerous. The program will also landscape erosive areas next to the creek and trails, planting native plants that support wildlife, and install wayfinding and regulatory signs at the loop trail entrances, which are main entrances to the park.

GLEN CANYON NETWORK IMPROVEMENTS

An extensive trail network winding through the canyon's grasslands offers magnificent views as well as connections to neighborhoods surrounding the canyon. Segments of some of these trails will be realigned, and retaining walls and steps installed, to improve safety and access and to reduce erosion. Trailside vegetation will be restored, and signs installed at trailheads and junctions to guide park users.

ISLAIS CREEK REGIONAL TRAIL

The Islais Creek Trail allows park users to experience the creek up close. The Urban Trails Program will upgrade this trail to improve water quality and access in areas that flood seasonally, and will build a new section of trail through the creek's upper corridor to Portola Avenue, thereby linking the Glen Canyon and Twin Peaks trail networks. Wayfinding signs will be installed to guide users at key trail junctions, and aggressive invasive plants along the trail will be removed and replaced with plants that offer high habitat value.
