excavated slopes. Portions of the excavated slopes in the alluvial deposits should be protected from erosion. The report recommends that cut-off ditches be constructed around the perimeter of the excavation site to divert surface water drainage away from the cut slopes. Biological Jones and Stokes conducted kit fox den surveys on the project site. The results of the surveys were put into a report that was included in the application materials submitted by Teichert. The purpose of the report was to assess the site's potential to support the federally endangered and state threatened San Joaquin kit fox. The site is currently an orchard. Ms. Sheila Larsen of the U. S. Fish and Wildlife Service (USFWS) was contacted. She agreed that den surveys would be adequate and that protocol-level surveys were not necessary. Protocol-level surveys usually include camera stations and nighttime spotlighting. The entire site was walked and dens were located. A den was classified as a potential kit fox den if the diameter was 4 to 10 inches for its entire visible length. One potential den within the 30-foot buffer around the perimeter of the excavation site in the northeast corner was identified. The conclusion of the report is that orchards are not suitable habitat for the kit fox and, further, that the one potential kit fox den is outside the mining area. Teichert, however, has set aside an area that is 200 feet by 680 feet in the northeast corner, just to be on the safe side. Dust It is not anticipated that this quarry will generate additional dust or air pollutants. This project will be replacing the Rose Pit to the north, which is nearing completion. The material that is excavated will be processed at Teichert's Tracy Rock Plant across MacArthur Drive. The response received from the San Joaquin Valley Air Pollution Control District concurs with this conclusion. Noise A noise analysis for the project was prepared by Brown-Buntin Associates, Inc., and submitted with the application. Existing noise measurements and accepted modeling techniques were used to predict noise levels resulting from the proposed quarry operations on the Traina property. There are two residences located approximately 200 feet south of the southerly project property line. The Development Title requires that the sound level at the property line shall not exceed 65 dB Ldn. The report concludes that scraper operations should not occur within 400 feet of the two southerly residences during the nighttime hours from 10:00 p.m. to 7:00 a.m. A Condition of Approval has been developed to reflect this recommendation. Traffic As noted earlier, the Traina property quarry will be replacing the Rose Pit that is located immediately to the north and nearing completion. Fehr & Peers Associates, Inc., prepared a traffic analysis that was included with the appliation materials. No increase in production levels is anticipated, and therefore,traffic volumes are expected to remain constant. The existing equipment crossing will be relocated further south to provide access to the Traina property site. Teichert Aggregates has prepared a Traffic Control Plan (TCP) to maintain the safe crossing of equipment across MacArthur Drive. Public Works' Conditions of Approval recommend that the first 100 feet of the San Joaquin County OX-96-2/Teichert Community Development Page 8
