The Maryvale Area Drainage Master Study (ADMS) examined approximately 100 square miles within the cities of Peoria, Glendale, Avondale, Tolleson and Phoenix, and unincorporated Maricopa County. The study area was bounded on the north by the Arizona Canal Diversion Channel and Skunk Creek; on the east by Interstate 17; on the south by Interstate 10; and on the west by the Agua Fria River, New River and State Route 101-L. The Maryvale area had drained mainly from north to south and from east to west via surface flow across streets, storm drains, and freeway channels, with all runoff ultimately discharging into the New River or Agua Fria River. This system generally lacked the capacity to convey runoff from large storm events. Particular ponding issues had historically been noted along the Grand Canal, Roosevelt Irrigation District Canal and Grand Avenue.

The ADMS ultimately recommended detailed study of potential solutions along Grand Avenue and the Grand Canal.


The study was completed in 1997. Signficant capital projects resulting from this study have included the Bethany Home Outfall Channel, the Maryvale Stadium West Inlet Channel and the 26th Avenue and Verde Lane Basin.
