Project Information Sheet

Perimeter Trail Maintenance

Arastradero Preserve (Palo Alto, CA)
Spring 1999


The trails in Arastradero Preserve receive heavy use from all visitors during every season. Due to the heavy clay soils and drainage patterns, many of the trails are especially vulnerable to damage and require frequent maintenance. Typical problems include ponding and ruts due to lack of proper drainage, berms on the outside of trails and lack of tread definition. Brush also crowds the trails in some locations.

     The City of Palo Alto's site includes a map of the preserve.

     Trail Center volunteers rerouted several hundred feet of the Perimeter Trail in 1998, closed a volunteer trail and repaired erosion damage.

Project Description:

Perimeter Trail (Apr. 24 and May 8): Volunteers repaired tread and improved drainage on the trail between Portola Pastures stables entrance and Gate B. Old barbed-wire fence was removed, brush trimmed and tread restored to full width in most locations. Some drainage problems were beyond the scope of the project or were too wet to repair during spring months and will be addressed later.

Technical Specifications:
Trail Width: 3.5-4 ft.
Maximum Grade: 10% for new construction; existing grade for maintenance
Outslope: 2-3% (standard)
Flagging: At grade level (consult crew leader)
Hazards and Other Considerations: poison oak, wasps (possible), ticks
Expected Number of Workdays: 2
Access to Worksite and Parking: Parking at Preserve main lot, along Alpine Rd. near Page Mill intersection, Page Mill Park & Ride
Water, Restrooms, Picnic Area: Water and restrooms at main lot (or as arranged); picnic area to be announced at workday
