sufficient capacity to accommodate the quarry traffic through the year 2010 even with the build-out of other approved projects in the vicinity. Biological Resources The quarry application includes a "Biological Resources Survey and Assessment for the Landmark Lathrop Group Golf Course Site" prepared by Moore Biological Consultants (Note: the golf course aspect has been dropped from the proposal). That assessment, dated January 19, 2000, includes the following conclusions and recommendations: • There are no general vegetative or wildlife resources that would be negatively impacted by the proposed project. The site is presently used for orchards, and orchards provide very low quality wildlife habitat. • The are no wetland resources which would be negatively impacted by the proposed project. • Croplands surrounding the site represent suitable Swainson's hawk foraging habitat. Swainson's hawks may nest in trees in the greater project vicinity. • Burrowing owls were not located occupying burrows in or near the project site during the 2000 survey. However, annual grassland habitats and berms supporting numerous ground squirrel burrows adjacent to the site represent suitable burrowing owl burrow habitat that could be used in the future. Moore Biological Consultants Recommendations 1. A pre-construction survey for nesting Swainson's hawks within 0.25 miles of the project site boundaries should be conducted prior to construction if construction is scheduled to occur between March 1 through September 15. In the event that nesting Swainson's hawks are located, take avoidance measures should be undertaken as described in CDFG's Staff Report regarding Mitigation for Impacts to Swainson's Hawks(CDFG, 1995). 2. Pre-construction surveys for burrowing owls within 250 feet of the project boundaries should be conducted prior to construction if construction is scheduled to occur between February 1 and August 31. In the event that active burrowing owl burrows are located, take avoidance measures should be undertaken as described in CDFG's Staff Report on Burrowing Owl Mitigation (DCFG, 1994). The above recommendations are included in the Conditions of Approval and are expected to reduce the potential impact to biological resources to less than significant. The application also included an evaluation for Riparian Brush Rabbit Habitat for the Landmark Lathrop Group Quarry Site dated January 10, 2001. That study was intended to supplement the earlier study. The Riparian Brush Rabbit Habitat study concluded that this project would not have a significant impact on the Riparian Brush Rabbit or its habitat.
