Reasons for Exemption
A list of special status plant and wildlife species with the potential to occur within the project area has been compiled based on a literature search of the California Department of Fish and Wildlife’s (CDFW) California Natural Diversity Database (CNDDB). A Field survey was conducted to identify potential biological resources within the project vicinity and determined a minimal probability of special status species on the proposed Project site. The habitat upon which the proposed project would be installed on is heavily disturbed and generally unsuitable for native flora and fauna. The local biota consists of typical wetland/riparian tree species of the Riverside region. The proposed project area contains mostly Arundo donax, an invasive species, on the lake bank. No existing native vegetation would be removed. The installation of the stream gage would not significantly disturb the local ecology. No large machinery equipment would be utilized, and ground disturbance would be minimal. The proposed construction activities would take place outside of nesting season (February 15 to September 15) to mitigate impact to the local and migratory bird population. A pre-construction survey for bird nests and burrowing owl would be conducted within 3 days prior to start of construction. No pedestrian or vehicle traffic restrictions would be necessary during the installation or operation of the proposed project. Impacts to biological, water, air, aesthetic and cultural resources would be minimal. There would be minimal impact to the lakebed of Temescal Canyon Lake. Therefore, no environmental regulatory permits would be required.
