The Broadway and Rural Drainage Master Plan will identify existing flooding hazards and recommend strategies to mitigate these flooding hazards to protect public safety in a five-square-mile area within the City of Tempe. The study area boundaries are the Loop 101 Pima Freeway on the east, the Union Pacific Railroad spur just west of Mill Avenue on the west, the U.S. 60 Superstition Freeway on the south and the Union Pacific Railroad (just north of Broadway Road) on the north. The project is a partnership between the Flood Control District of Maricopa County and the City of Tempe.

This project is being conducted to identify locations within the study area that are periodically subject to flooding caused by rainstorms. The project will develop strategies to reduce possible flood damage to existing structures. Preliminary analysis has indicated that certain portions of the study area are prone to periodic flooding and possible property damage during large rainstorms.

The project began in 2010 with a computer model analysis illustrating the effect of different rainstorm intensities on the residences, businesses, streets and drainage facilities in the study area. As additional analyses continue and the project team documents firsthand accounts of flooding from area residents and property owners, the project will develop alternatives to mitigate potential flooding caused by rainstorms.


The project team completed the technical modeling effort and data collection of flooding information from residents located in the study area and identified three significant problem areas within the study boundary (areas where existing homes were determined to be vulnerable to flooding or which had experienced multiple drainage and/or flooding problems). The areas included the Mill Avenue corridor, the Daly Park neighborhood, and the Loma Vista/McClintock neighborhood. The project team investigated alternative solutions to provide mitigation for these three areas. The Mill Avenue Corridor and the Daly Park neighborhood flooding conditions cannot be solved cost effectively with a local fix and require a more regionalized approach. These problems were documented and will be addressed as part of the larger Tempe ADMS study. A feasible flooding mitigation solution was developed for the Loma Vista / McClintock area. The City of Tempe submitted this project to the District’s CIP Prioritization process in June 2013. The project was conditionally approved and is now in the District’s CIP tentatively scheduled for FY18. Project partners will include the City of Tempe and the Tempe Union High School District-McClintock Campus.
