The City of Phoenix plans to install a 25 million gallons per day (MGD) sewer lift station, gravity sewer, and a water line within the City of Phoenix in Maricopa County, Arizona (Figure 1). The gravity sewer will be constructed along Southern Avenue, between 55th and 75th Avenues. The lines for this facility will be located in a 25 m (82 ft) wide area that will extend, from east to west, roughly down the center of Southern Avenue (Figure 1). This sewer will terminate at a proposed 25 million gallons per day (MGD) permanent lift station, located on 75th Avenue (approximately one-half mile south of Southern Avenue (Figure 1). The lift station discharge will be carried north by force mains, through the Salt River Crossing, along the 75th Avenue alignment, to Broadway Road (Figure 1). The waterline will be extend from the lift station, north along 75th Avenue, and east along Southern Avenue to 67th Avenue. Along Southern Avenue, the water line will be located in the 25 m area for gravity sewer lines.

Private developers are also constructing a gravity sewer along Southern Avenue at 51st Avenue. The flow from this sewer will initially discharge into a temporary (privately developed) 2 MGD sewer lift station located at 55th and Southern Avenues. Once the City of Phoenix finishes construction of the 25 MGD lift station along 75th Avenue, and the forcemains across the Salt River, the 51st Avenue sewer will flow directly into the larger lift station. These gravity sewers are part of a planned system that will service future development in the West Laveen area.

Logan Simpson Design Inc. (LSD) was retained by Stanley Consultants Inc. (Stanley), on behalf of the City of Phoenix, to perform a Class III archaeological survey of 75th Avenue, from 0.75 mile north of Baseline Road to 18.3 m (60 ft) north of Broadway Road, and of Southern Avenue from 51st Avenue to 75th Avenue (Figure 2). Although the City project only extends east along Southern to 55th Avenue, Southern was surveyed to 51st Avenue at the request of Todd Bostwick (City of Phoenix Archaeologist). The survey investigated a 366 m (1,200 ft) corridor centered on 75th Avenue, and a 46 m (150 ft) corridor centered on Southern Avenue (Figure 2). The Class III archaeological survey resulted in the identification of six previously unrecorded archaeological sites, and investigation of three previously recorded sites. Fifteen isolated occurrences were also recorded (Grafil 1999).
