Wetland and Biological Assessment Habitat Assessment for the California Tiger Salamander and the California Red-Legged Frog: A Habitat Assessment for the California Tiger Salamander and the California Red- Legged Frog report was prepared by Olberding Environmental, Inc., based in Concord, CA. The report cited that California Tiger Salamander (CTS) were sighted 0.75 miles east of the project site in 1999 and that adult CTS were sighted one mile north northwest of the project site in 2002. The report found that although no breeding habitat exists on the project site, but that CTS movement onto the project site could potentially occtu from areas in the vicinity. The report assessed the project site for its potential to serve as a California Red-Legged Frog (CRLF) breeding habitat. The report stated the CRLF is typically found in Cold- water ponds and stream pools; thus, CRLF are unlikely occur within the project site. Other Biological Resources: A Biological Resources Analysis report was also prepared by Olberding Environmental, Inc. Nine special-status plant species were identified as having the potential to occur o the property site based on the presence of suitablc habitats. However, none of the species were observed in the field survey during the blooming season. This report identified three special-status amphibians, including CTS, CRLF, and the foothill yellow-legged frog that have the potential to occur in the general vicinity of the project site but not within the project area. The project site has annual grassland habitat that is considered potentially suitable for the snake, but due to the lack of nearby occurrences, and shrub cover, this species in considered unlikely to be present on the site. The report also investigated the possibilities of having special-status reptiles and mammals present on the project site. The report finds that due to the lack of nearby occurrences, these species are considered unlikely to be present on the project site. The eucalyptus tree located off site is considered to be a suitable nesting habitat for the golden eagle, red-tailed hawk; however, it should not be disturbed by the proposed development. Tall grasses within the annual grassland habitat could potentially be used as nesting habitat by the northern harrier, however, human disturbance and graving are considered likely deterrents to this species. Additionally, the tall grassland habitat is considered potentially suitable nesting habitat for the California horned lark. However, there are no occurrences of it within five-mile radius of the project site. If nesting is observed, the report recommends that construction only be allowed outside the nesting period. Staff has included a condition to address this recommendation. Wetland Delineation: The U.S. Army corps of Engineers Wetland Delineation report was prepared by Olberding Environmental, [nc. The report identified a total of 0.21 acres Case No. PUD-77 Planning Commission Page - 9 -
