Project Type: Study

Project Description:

The Downtown Mesa Area Drainage Master Study (ADMS) is underway to investigate, identify and assess existing flooding problems. A part of the larger North Mesa ADMS, the area 3 “Downtown” covers downtown Mesa, the area between the Mesa city boundary to the west and north, the Consolidated Canal to the east, and the US 60 freeway to the south. This study will be used to establish guidance for future developments to protect public safety within the 20-square-mile study area.

PROJECT HISTORY
There have been several 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 storm drain 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.

NORTH MESA ADMS
The North Mesa 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 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 District has divided the ADMS into geographical areas for focused further analysis. Three areas comprising portions of the North Mesa ADMS are currently under study.

• Area 1 "Apache" is the watershed north of Apache Trail from Sossaman Road to Meridian Road. COMPLETE
• Area 2 "Southtown" is the watershed south of Apache Trail to the US 60 freeway from Loop 202 to approximately Meridian Road. COMPLETE
• Area 3 "Downtown" covers downtown Mesa, the area between the Mesa city boundary to the west and north, the Consolidated Canal to the east and the US 60 freeway to the south.
