The North Mesa Area Drainage Master Study (ADMS) is a regional drainage study being conducted in the Mesa area north of US 60 by the Flood Control District of Maricopa County. The study, which encompasses portions of the City of Mesa and unincorporated Maricopa County, will analyze a 116 square mile area bounded by the Tempe Canal (just east of the Price Freeway) to the west, the Salt River to the north, the Maricopa County boundary to the east, and US 60 to the south (study area map). The area incorporates residential areas with commercial corridors.
The purpose of the North Mesa ADMS is to investigate, identify and assess existing flooding problems. A comprehensive inventory of known flooding problems impacting the study area is being compiled from past flooding information provided by the City of Mesa as well as a review of previous drainage studies.
There have been a number of studies conducted for this area over the years, including the Spook Hill ADMP (2004), Higley ADMP (2000), East Mesa ADMP (2014), and Eastern Maricopa County ADMS (1987). There are also two areas that have not previously been studied: the Lower Eastern Maricopa Floodway Part 1 and the Lower Verde. In 2010, the City of Mesa completed a stormdrain master plan that reviewed hydrology from the previous studies but did not incorporate new hydrology.
A comprehensive hydrologic analysis will be conducted and will include current rainfall parameters and current land use conditions. This study will also review the status of previously recommended stormwater facilities, determine what has been built, and prioritize any facilities that may still be needed.
The District has broken the ADMS into geographical areas, or sub-watersheds, for focused further analysis. Three areas comprising portions of the North Mesa ADMS are currently under study.
The initial data collection report for the North Mesa ADMS was completed in August 2015. For Area 1, the District has completed its final two-dimensional hydrologic model and prepared a Technical Memorandum outlining practical, efficient, small-scale, and cost-effective flood proofing measures for reducing the impact of storm water on low-lying homes. For Area 2, the District recently completed its final two-dimensional hydrologic model. For Area 3, the District will be conducting data collection and public outreach over the next several months, as well as creating a base two-dimensional hydrologic model.
