San Joaquin County Community Alternatives Analysis Development Department Chapter 3. The site would remain in agricultural production. There would be no change to the physical or visual character of the site. No new air pollutant emissions or noise would be generated from the project site and no change to existing hydrology or water quality would occur. No change in wildlife habitat would occur. No-Project-generated traffic would be added to roadways and no access road would be constructed off of Koster Road. This analysis assumes that the SR 132Bird Road Interchange project would be constructed and that ongoing mining operations in the project area and increases in aggregate production related to other mining projects in the vicinity would occur. Traffic conditions would continue to worsen as described in section 3.L, "Transportation and Traffic,"and in Appendix F. However, the No-Project Alternative would not contribute to these changes in traffic conditions. Other Project-specific impacts described in Chapter 3 also would not occur should the existing physical — conditions on the project site persist. Off-Site Processing Operation Alternative The impacts of this alternative would be similar to the proposed Project for all — resource areas except aesthetics, air quality, and transportation and traffic,which are discussed below. Aesthetics Under this alternative,the processing equipment(crushing and washing), stockpiling, and material production(asphalt and concrete)operations would not occur at the site, substantially reducing the amount of visible aggregate processing equipment that would be visible at the site. Under this alternative, the perimeter berm would still be constructed as part of initial site preparation and mining operations. The perimeter berms would be approximately 5 feet tall and would be landscaped to visually screen the site and soften views of the berms. Views from the ground level of excavation equipment would be screened by the proposed perimeter berms,as excavation of aggregate materials(sand and gravel)would occur below surface level and are not anticipated to be visible from area roadways or residences. The aesthetic impacts of the proposed Project would still occur under this alternative,but would be substantially reduced since the aggregate processing plants would not be constructed at the site. This impact would be less than significant. Air Quality Under this alternative, construction-related emissions associated with construction of the processing facilities would not occur, as these facilities would be eliminated.
