In response to previous flooding conditions, the District conducted the East Maricopa County Area Drainage Master Study (ADMS) in partnership with the City of Mesa, the Maricopa County Department of Transportation and the U.S. Soil Conservation Service (now NRCS). The study area was bounded by the Buckhorn-Mesa flood retarding structures (north), the Powerline Floodway and Elliot Road alingment (south), and the Roosevelt Water Conservation District Canal (west).

This was the first formal ADMS conducted by the District. Prior to the ADMS, flooding in 1983 exceeded the capacity of existing channels and streets, damaging and flooding many residences in the developed portion of the study area. Again, in 1984, the study area was subjected to localized flooding in the vicinity of University Drive and the Central Arizona Project Canal - in some areas, three to four feet of water ponded, flows reached 2,500 cubic feet per second, and embankment failures occurred. The ADMS evaluated existing and possible future hydrologic conditions in a 68-square mile area for purposes of defining area hydrology and providing a database framework for the area. Study results were intended for use in stormwater planning. The ADMS had the additional goal of reducing peak inflows to the East Maricopa Floodway, under construction at the time by the District and the Soil Conservation Service.


The ADMS was completed in 1987.
