The South Phoenix Drainage Improvement Project Feasibility Study evaluated the watershed generally bounded by 43rd Avenue to the west, 16th Street to the east, South Mountain to the south and the Salt River to the north. The study identified and compared alternative solutions to mitigate flooding hazards in the watershed and selected a recommended plan.

The contract includes hydrologic and hydraulic analyses and the final design of a detention basin located at 27th Avenue and South Mountain Avenue and a detention basin located at 43rd Avenue and Baseline Road that will discharge into the previously-constructed storm drain system and, combined with collective plan features, will further mitigate flooding hazards in the subject area with a goal of providing an overall 100-year level of protection. The contract scope further includes associated post-design services. The Flood Control District of Maricopa County (District) will act as the lead agency for all Project responsibilities and the City of Phoenix will own, operate and maintain the Project upon completion.
