The project would result in the construction of a parallel outfall pipeline, a side-bank outfall structure,three large- <br /> diameter wastewater collection system pipeline alignments, a recycled-water-distribution pipeline system, and an <br /> expanded WQCF. In addition,the project would result in the construction of several wastewater pumping stations. <br /> Pipelines constructed as part of the proposed project(including the collection system sewers,recycled-water <br /> distribution system, and the outfall pipeline)would be underground and would not be visible and would not <br /> degrade or substantially change the visual character of the project area. The new side-bank outfall structure would <br /> be similar in size and mass to the existing outfall structure. <br /> Although specific wastewater pumping station locations are not known at this time,pumping stations would be <br /> similar in appearance to the existing facility at Woodward Park. Permanent pumping stations would be <br /> constructed in the Union Ranch development north of Lathrop Road and at the westerly terminus of Woodward <br /> Avenue near the Tara Park development in southwest Manteca, and interim pumping stations may be constructed <br /> in other developed subdivisions depending on the completion schedule of the wastewater collection system <br /> pipelines. Pumping stations would be predominantly below grade, and landscaping and fencing would be <br /> provided and would allow the pumping stations to visually blend with residential surroundings(Exhibit 4.2-6, <br /> Viewpoints 9 and 10). <br /> WQCF site structures would be similar in size and mass to existing on-site facilities. In general,off-site views of <br /> the treatment facilities would not substantially change from existing conditions. The facilities would still be <br /> visible in the distance,but would appear to be denser because of the increased number of buildings on-site and <br /> would blend in with existing facilities because residences, commercial buildings,row crops, orchards, and other <br /> vegetation would continue to serve as a visual screen from some viewpoints. <br /> Because pipelines associated with the proposed project would be underground and would not be visible and <br /> would not degrade or substantially change the visual character of the project area,the new side-bank outfall <br /> structure would be similar in size and mass to the existing structure,pumping stations would visually blend with <br /> residential surroundings, and WQCF site structures would be similar in size and mass to existing on-site facilities, <br /> the project's visual impacts would be less than significant. <br /> IMPACT Visual Resources—Impacts of Construction-Related Nighttime Lighting.Project construction could, at <br /> 4.2-4 times, continue past dusk. High-intensity lighting may be used to illuminate construction sites associated <br /> with the WQCF site,pumping stations,parallel outfall pipeline, and pipeline alignments. This lighting could <br /> be visible to nearby residences and could contribute to skyglow in the surrounding area.Although <br /> construction-related lighting would be temporary, it could result in intrusive glare in areas adjacent to project <br /> construction sites. This would be a potentially significant construction-related lighting impact. <br /> Lighting associated with construction activities could potentially affect sensitive visual receptors located in the <br /> vicinity of the project. If construction activities continue past dusk,high-intensity lighting would be required to <br /> illuminate construction sites. This would be a substantial additional source of lighting beyond the existing lighting <br /> at the WQCF site,pumping station sites, and along pipeline alignments. Existing nighttime lighting sources at the <br /> WQCF site consist of emergency and other facility lighting. Although nearby overhead pole lighting associated <br /> with the Big League Dreams recreational softball complex and the Stadium Center shopping area also contribute a <br /> significant amount of nighttime lighting to the WQCF area, construction lighting may be needed during periods <br /> when lighting is not needed at the softball complex and shopping area. Therefore,project construction lighting <br /> could be visible at the WQCF site and nearby residences to the north, east, and west. Because construction <br /> lighting could be visible to residences near the WQCF site,pumping station sites, and along pipeline alignments, <br /> and could result in intrusive glare in adjacent residential areas during nighttime hours,this would be a potentially <br /> significant construction-related lighting impact. <br /> EDAW Manteca WQCF and Collection System Master Plans EIR <br /> Visual Resources 4.2-12 City of Manteca <br />
