Document Description
The objectives of these projects are to increase public and first-responder safety and reduce fuel loading through vegetation management and fire hand crew operations throughout Irvine’s open space areas. Methods include maintaining existing defensible space and the Irvine Legacy fuel breaks, and using hand and mechanical treatment to scrape, cut, chip, and pile, beginning in the spring of each year and continuing annually based on resource availability. The level of treatment varies with the type of vegetation present, ranging from maintaining fuel breaks by cutting and chipping vegetation (leaving root systems intact) to maintaining fire roads, where residual trees and shrubs are thinned and limbed to appropriate dimensions for effective fire resilience. Hand crews and mechanical equipment, including chainsaws, pole saws, chippers, mowers, and weed whips, are used to cut, prune, thin, chip, and mow vegetation. This project includes maintaining linear features, such as roads and fire road access, which involve cutting vegetation within the road right-of-way and a width of approximately 10 feet on each side to enhance emergency ingress and egress. Prescribed grazing is used in designated areas, as appropriate, to support targeted vegetation management.
Project activities are confined to previously disturbed, actively managed corridors within the established Irvine Legacy fuel break and fire road network. No new ground disturbance, habitat conversion, or expansion of the existing operational footprint is proposed. A California Natural Diversity Database (CNDDB) query was completed for the project area; no sensitive species with potential to be significantly impacted were identified. Operations will maintain a minimum 50-foot avoidance buffer from known cultural or archaeological resources, and a biological review will be conducted annually by a qualified biologist. Work near sensitive or listed biological resources will be conducted under the guidance of a qualified biological monitor, who will establish appropriate species-specific buffers in the field as warranted. No heavy equipment will be used in watercourses or within the Watercourse and Lake Protection Zone.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Section 15304, Class 4 – Minor Alterations to Land
Reasons for Exemption
This project fits under Class 4 – Minor Alterations to Land for the maintenance of existing wildland fuel breaks and fire roads within previously disturbed operational areas. The Irvine Legacy fuel breaks are located outside the City's NCCP/HCP Reserve System within previously disturbed, actively managed corridors, and no new ground disturbance, habitat conversion, or expansion of the existing operational footprint is proposed.
Field review by City of Irvine Public Works and Sustainability Department staff confirmed that no exceptions preclude the use of a notice of exemption for this project. The City has concluded that no significant environmental impact would occur to aesthetics, agriculture and forestland or timberland, air quality, biological resources, cultural resources, geology and soils, greenhouse gas emissions, hazards and hazardous materials, hydrology and water quality, land use planning, mineral resources, noise, population and housing, public services, recreation, transportation or traffic, utilities and service systems, or to wildfire.
