IMPACT Transportation and Circulation—Potential for Inadequate Parking Capacity. Implementation of the 4.11.3 proposed project would result in the creation of a small demand for additional parking spaces during the regular working shift at the WQCF. However, adequate space is available at the WQCF site for additional parking spaces, and additional parking spaces would be included in final project design.Adequate space also exists in the project area to adequately accommodate vehicles and equipment associated with construction of pumping stations, the outfall pipeline, and pipelines for the wastewater collection system and recycled-water distribution system. Therefore, the proposed project would not result in inadequate parking capacity. This impact would be less than significant. Currently, staffing at the WQCF consists of approximately 20 people. At WQCF buildout, approximately 30 staff members would be needed to operate the WQCF. Therefore,demand for on-site parking spaces would increase. The WQCF site occupies approximately 22 acres of a 210-acre City-owned property. Implementation of the proposed project would result in the expansion of the WQCF footprint onto City-owned farmland surrounding the WQCF. Sufficient space exists both within and outside the existing WQCF footprint for the construction of additional parking spaces, and additional parking spaces to accommodate increased parking demand would be included in final WQCF site design. Therefore,the proposed project would be consistent with City general plan parking Policy C-P-26. In addition,no off-site or on-street parking would be necessary to accommodate WQCF site parking needs. During peak construction activities, 80 construction workers could commute to the WQCF site daily, generating approximately 160 one-way vehicle trips per day. In addition, 50 construction workers would commute to pipeline and pumping station sites on a daily basis,generating approximately 100 one-way vehicle trips per day (Richard,pers. comm., 2006a). The proposed project would temporarily increase demand for parking during the construction period to stage construction equipment and construction personnel vehicles. The WQCF site has several open areas (e.g.,north of the ultraviolet light disinfection facilities and east of the primary sedimentation basins)to adequately accommodate construction-related vehicles within the footprint of the site. Sufficient space also exists in the project area to accommodate vehicles and equipment associated with construction of pumping stations,the outfall pipeline, and pipelines for the wastewater collection system and recycled-water distribution system. Construction staging areas along proposed pipeline routes and roadways would be designed to accommodate all the parking needs of construction equipment and construction personnel vehicles and minimize hazards to roadway users (see Impact 4.11-4). Because sufficient space exists both within and outside the existing WQCF footprint for the construction of additional parking spaces,because additional parking spaces to accommodate increased parking demand would be included in the final WQCF site design, and because construction staging areas at the WQCF site and along proposed pipeline routes and roadways would be designed to accommodate all the parking needs of construction equipment and construction personnel vehicles and minimize hazards to roadway users,this impact would be less than significant. IMPACT Transportation and Circulation—Increase in Hazards because of a Design Feature. No permanent 4.11-4 design features are proposed that would increase hazards for pedestrians, bicyclists, or drivers. Standard construction practices(i.e., cones, signage, traffic controllers) would be employed during project construction to minimize any potential hazards. However, construction-related vehicle trips associated with construction of the proposed WQCF improvements, outfall pipeline,pumping stations, and pipelines for the wastewater collection system and recycled-water distribution system may block some roadways and result in the queuing of vehicles on area roadways. This could increase the potential for vehicle accidents and could temporarily increase response times for emergency service vehicles. Therefore, this impact would be potentially significant. The proposed WQCF facilities would be constructed at the existing City-owned WQCF site. Project construction would require construction equipment and heavy vehicles, such as scrapers, cranes, and dump trucks,to be stored Manteca WQCF and Collection System Master Plans EIR EDAW City of Manteca 4-11.9 Transportation and Circulation
