4.Alternatives t^� Traffic and Circulation As noted above,under this alternative all nighttime truck traffic would be required to enter and exit the Munn& Perkins facility via westbound E. River Road.As the traffic analysis in the EIR assumes that all project traffic could potentially use either the east or west haul route,the potential F traffic impacts of the West Only Haul Route would be'the same as the proposed project for E.River Road and McHenry Avenue.However,in order to serve projects located east of the plant,haul trucks Would need to use an easterlyconnector such as Highway 219/Claribel Road. This increase would not necessarily be significant, given the lower traffic levels experienced at night in the area. R' Air Quality and Climate Change ` Impacts to air quality may occur under this alternative due to potentially increased haul distances to serve easterly projects(see traffic discussion above).Delivering material to the east would require increased haul distances,resulting in increased criteria pollutanis and greenhouse gas emissions.These increases are not necessarily significant,but would represent an increase over the proposed project. �► Noise As noted above,this alternative would reduce noise related impacts to sensitive residential al receptors located east of the project site entrance along E. River Road. However, residences west of the project site entrance along E. River Road would still experience noise related impacts during �= nighttime operations.Therefore,the overall.number of receptors would be reduced,but the remaining westerly receptors will still be impacted. Additionally,the westerly receptors could experience an increase in the number of nights with extended operating hours, as haul trucks headed to the -� east would still have to pass by on their way to McHenry Avenue. 4.2.3 Alternative 3 — East Only Haul Route Alternative Description ,- This alternative would require all nighttime truck traffic to enter and exit the facility via eastbound E.River Road.Trucks would be required to utilize Santa Fe Road in order to reach E.River Road. This haul route reduces the significance of noise related impacts to sensitive residential receptors located west of the project site entrance along E.-River Road. However, residences east of the project site entrance along E. River Road would still experience noise related impacts during nighttime operations. Distinctive Environmental Characteristics The following summarizes potential impacts of the east only haul route alternative and compares them to the impacts of the proposed project: L Visual and Lighting The east only haul route alternative would result in the same impacts(less than significant)to l visual resources as the proposed project. t Munn&Perkins Quarry Excavation Permit - -rJ - ESA 7211086 Draft EIR - - April 2011 -_
