Peters Canyon General Development Plan

Project Information

In 1992, the Irvine Company dedicated 340 acres of land to the County to be preserved as open space which is now called Peters Canyon Regional Park. The rolling hill and valley topography of the park offers visitors 8 miles of trails through a variety of native habitat areas. Plant communities consist of endangered coastal sage scrub, grasslands, oak, sycamore and willow woodlands, and non-native eucalyptus groves. Trails offer beautiful views of the mountains to the east and north and also to the 55-acre water body known as Peters Canyon Reservoir.

OC Parks is in the process of finalizing a General Development Plan (GDP) and Resource Management Plan (RMP) for the park. The GDP and RMP will examine the physical, natural and cultural conditions of the park and its surrounding areas and provide a master plan that addresses current and future park programming needs, including parking, trail access, regional connectivity, and long-term management plans for ecological and hydrological sustainability within the park.
