Document Description
The project area is ~973 acres located in the City of Irvine, south of highway 241, west of Alton Parkway, north of Irvine Boulevard, and east of the community of Portola Springs. The elevation on the project site is approximately 500’ to 600’ above mean sea. Environments on the project site are mostly degraded/ruderal due to a history of fire, including the 1998 Santiago Fire and the recent 2020 Silverado Fire, which burned through the entire property. Vegetation across the project area consists of mostly annual grasslands, invaded by black mustard, as well as degraded coastal sage scrub composed of isolated oak trees, small stands of cactus, with larger shrubs such as laurel sumac and lemonade berry, and thin ribbons of mule fat riparian. Every year there are dozens of roadside ignitions along roadways in Orange County and the goal of the project is to reduce the spread of fires by reducing hazardous fuels through prescribed burning. The project will provide a direct benefit to over 1500 homes, critical infrastructure, and nearly 50,000 acres of adjacent wildland by providing a buffer of reduced fuels and reduction of ignition potential. This project will also include providing wildland fire training opportunities to firefighters in the form of live fire training and suppression tactics. The project will reduce the risks associated with wildfire to the habitable structures in the nearby cities of Irvine and Lake Forest, as well as open space owned by the County of Orange. This project will provide much needed training and fuels reduction in an area of high fire frequency to reduce fire intensity and fire occurrence. By conducting prescribed fire and reducing hazardous fuels during a planned burn window, the health and social wellbeing of nearby residents and adjacent communities will improve during a wildfire, as the project will reduce the amount of greenhouse gasses and carbon emitted into the environment and atmosphere during a wildfire in the area.
