Introduction
Species listed in Table D‐1 are those occurring in the California Natural Diversity Database (CNDDB) within 1.0 mile of any of the project alternative sites. CNDDB occurrences were compared with site boundaries to determine whether or not each species has occurred on any of the sites. Some CNDDB occurrence locations are unspecific (i.e, the exact location is concealed or not known), and where it was unclear whether an occurrence was associated with a site, a question mark (“?”) was assigned for occurrence. “Potential for occurrence” was based on an examination of aerial photos and considerations of range, habitat preferences, and elevation. If a site was designated “yes” for occurrence, it was also designated as such for potential to occur. Maps identifying the potential species located within the 1.0 mile radius of each alternative site are also provided for reference. D‐1 Table D-1.

1 Species listed are those for which CNDDB occurrences are within 1.0 miles of any of the eleven project alternatives. The EIR discussed the potential impacts to the American peregrine falcon (Falco peregrinus anatum), a state Fully Protected (FP) species and formerly both state and federally listed. Although the CNDDB query resulted in no
occurrences of this species, peregrine falcons are known to nest at Morro Rock, approximately 0.60 miles southwest of the Current WWTP Site and 0.45 miles west of the Power Plant Site. This species may occur in transit over both sites, but is unlikely to nest at either, or at any of the other alternative sites.
