Responsible Environmental Planning In aIl planning and design activities for the PWP, Aurora Water and its environmental consultant have coordinated and planned extensively to ensure compliance with federal and state laws such as the Endangered Species Act (ESA), Migratory Bird Treaty Act (MBTA), Clean Water Act (CWA), National and State Historic Preservation Acts (NHPA, SHPA), and the regulations administered by tne United States Fish and Wildlite Service (USFWS), Colorado Division of Wildlife (CDOW), Army Corps of Engineers (ACOE), and the State Historic Preservation Office (SHPO). Potential critical habitats for Preble's Meadow Jumping Mouse (PMJM), raptors, prairie dogs, and burrowing owls have been mapped, and the construction sequencing and activity constraints associated with these areas have been identified. Potential Waters of the United States and Wetlands have been evaluated to determine appropriate preservation requirements during construction. In addition, the conveyance system alignment, including a 1000-foot buffer, has been evaluated for paleontologic and other cultural resources of significance. Consultation with the State of Colorado's Historic Preservation Officer has identified acceptable mitigation measures for pipeline construction. The PWP has been strategically designed to avoid impacts to environmental and natural resources, as exemplified by the use of trenchless crossings as needed to avoid impacts to wetlands or Waters of the US, eliminating the need for any federal permits for construction of the PWP. Alternatives Analysis for the Conveyance System In 2004, Aurora Water and its team of professionals began identifying and evaluating alternative alignments for the conveyance system which will deliver water from the North Campus natural purification facilities to the South Campus. Three alternative preliminary pipeline alignments were carried forward from the initial screening process led by MWH in 2004: Transmission Alternative 1- E-470 Alignment Transmission Alternative 2- DIA East Alignment Transmission Alternative 3- Monaghan Road Alignment. All three aligninents start at the North Campus natural purification facilities located near Brighton. Each route offered distinct advantages pertaining to pipeline length; environmental factors; number of highway, railroad, irrigation ditch, stream, and utility crossings; number of landowners; and the extent of developed land traversed by the pipeline. Based on evaluation of the three alternatives, Alternative 1, the E-470 alignment, was carried forward as the preferred pipeline alignment. This alternative was selected primarily to streamline right-of-way acquisition and because it presented the fewest environmental impacts. Pumping stations are needed to lift the water approximately 1000 feet from the North Campus to the purification facilities at the South Campus (also known as the Aurora Reservoir Water Purification Facility or ARWPF). Locations for the pumping stations were identified at interim points along the conveyance system so that the same pump motor horsepower would be required at each of the pumping stations. Alternative sites were then
