Exempt Status
Categorical Exemption
Type, Section or Code
CEQA Guidelines § 15304 – Minor Alterations to Land (Class 4); and CEQA Guidelines § 15301 – Existing Facilities (Class
Reasons for Exemption
The Project meets the requirements of the Class 4 Categorical Exemption (minor alterations to land, CEQA Guidelines Section 15304), which expressly exempts minor public or private alterations in the condition of land and vegetation, and fuel management activities within 30 or 100 feet of structures. The Project also meets the requirements of the Class 1 Categorical Exemption (existing facilities), which expressly exempts the maintenance of existing public or private facilities including streets, and the maintenance of existing landscaping or native growth. Project implementation will result in minor alterations to the land, including fuel management activities, that will not significantly impact a scenic vista, scenic resources, or the existing visual character or quality of public views, biological and/or cultural resources, and will not involve the removal of healthy, mature, scenic trees for any purpose. Project implementation also involves maintenance of existing roadways, landscaping, and native growth. Vegetation treatment prescriptions are consistent with industry best practices for vegetation management and defensible space and will be approved by LAHCFD prior to implementation. All work will occur within or immediately adjacent to an established roadway, within 30 feet of structures, or within 100 feet of structures if necessary to address extra hazardous fire conditions. Project activities will not result in the taking of endangered, rare or threatened plant or animal species or significant erosion or sedimentation of surface waters. Project activities will not damage scenic resources within officially designated state scenic highways. There is no reasonable possibility that the Project will have a significant effect on the environment due to unusual circumstances that would preclude the use of a categorical exemption for this Project. Documentation of the environmental review completed by staff is kept on file with the District.
