Habitat Restoration Project at Peters Canyon Regional Park


OC Public Works will be removing non-native invasive trees within Peters Canyon Wash, which will require daily temporary trail closure and need for traffic control along the southern portion of the Mountains to Sea Trail. Peters Canyon Wash and Regional Park provide open space for recreation, water conveyance and offer California Native Habitat for diverse flora and fauna. This habitat restoration project will improve CA native habitat.

Peters Canyon Trail at Peters Canyon Regional Park to be used for access during habitat restoration work. Activities include site preparation, non-native tree and plant removals and plant establishment.

This project is being conducted in compliance with applicable state and federal environmental laws and regulations and is being implemented to offset environmental impacts from OCPW flood control channel maintenance projects.


OCPW and contractor personnel will be removing nonnative invasive tree species located throughout Peters Canyon Wash within the southern portion of Peters Regional Park. Equipment (skid steers, excavators, trucks) will enter the Park at Peters Canyon Rd., xst Silverado Terrace, and will use the maintenance road east of Lower Peters Basin, up through the “Mountains to Sea Trail”. (see map for locations) Each work day, 0.5 mile of the trail will experience temporary closures starting from the bathrooms at the southern entrance while equipment and dumpsters are delivered and removed.
