Notice of Exemption

Exempt Status
Statutory Exemption
Type, Section or Code
CEQA Guidelines Section 15269(C) Emergency Projects;
Reasons for Exemption
Many of the trees are dead or dying and some have fallen in the area and are deemed hazardous. The area is also subject to burning due to periodic wildfires, one of the recent fires reached a building at the adjacent water treatment plant. Removal of trees will prevent and mitigate future hazards.

Exempt Status
Categorical Exemption
Type, Section or Code
Class 1(H). Existing Facilities; Class 33. Small Habitat Restoration Projects
Reasons for Exemption
The proposed project includes (1) the removal of overgrown, dead, and dying non-native invasive eucalyptus trees, which were considered landscape trees for the Perdue Water Treatment Plant property; (2) maintenance and stabilization of the slope area; and (3) and replacement of removed landscape trees with fire-resilient native habitat. The proposed site does not exceed the 5-acrc limitation of Class 33t and it would eventually be resto1·ed from landscape nonnative invasive vegetation that is currently dead or in bad condition, to fire resilient native vegetation and potential habitat for sensitive wildlife species, including California gnatcatcher and cactus wren.
