Description:

Glendale/Peoria ADMP Update
The original Glendale-Peoria Area Drainage Master Plan was completed in 1987. This was one of the first comprehensive stormwater studies conducted by the District. The study area encompassed approximately 123 square miles that includes the City of Glendale, the City of Peoria, and contributing drainages bounded on the west by the Agua Fria River, on the north by the Central Arizona project (CAP) Canal and the New River Dam alignment, and on the east by the Hedgepeth Hills and Weir Valley.

The Glendale/Peoria ADMP Update reviewed approximately 85 square miles from the original study. The area of study for the Glendale/Peoria ADMP Update was comprised of all the area of the original study north of the Arizona Canal Diversion Channel (ACDC) and Skunk Creek, and west of the New River. The purpose of the Glendale/Peoria ADMP Update was to identify existing drainage problems and developed cost-effective solutions to alleviate known and potential flooding problems.

Glendale/Peoria ADMP Update Northwest Region
The Glendale/Peoria Area Drainage Master Plan Update (ADMPU) Northwest Region Update Hydrologic Study area is a portion of the original Glendale/Peoria ADMPU and includes a watershed of about 30 square miles located north of Union Hills Drive, west of New River, south of the Dynamite Boulevard alignment, and east of the Agua Fria River. This project was completed in 2007. The project lies entirely within the City of Peoria corporate limits.

Since the completion of the ADMPU, many developments had been constructed and new developments are planned which impact the size of recommended flood control facilities within the watershed. This study updates the hydrologic modeling to address the impact of recent development, future development and capital improvement projects (CIP) on the watershed hydrology within the study limits.

Glendale Area Stormwater Master Plan
The City of Glendale initiated the Glendale Area Stormwater Management Plan (SMP) to update the current Stormwater Management Plan that was completed in 1986. Numerous changes and improvements to the stormwater drainage system have been completed since 1986. These changes and improvements were developed in the Glendale/Peoria Area Drainage Master Plan and Update (ADMP and ADMPU respectively) and the Maryvale Area Drainage Master Study (ADMS).

The purpose of the hydrology update includes the following:

  • Evaluate the existing stormdrain system in the City of Glendale.
  • Evaluate the 10-year and100-year, 6-hour and24-hour storm events for the existing and future conditions for the two watersheds.
  • Provide a planning tool for formulating and analyzing alternatives for the Glendale SMP.
Original Glendale/Peoria Area Drainage Master Plan
The District, in partnership with the cities of Glendale and Peoria, completed the Glendale/Peoria Area Drainage Master Plan (ADMP) in 1987. The ADMP identified regional and municipal flood control and drainage features to mitigate area flooding hazards. Solutions generally involved a system of 2-year and 10-year capacity storm drains and basins.

Between 1980 and 1997, the population of Glendale and Peoria increased by 97 percent and 586 percent, respectively, and the District initiated an update to the original ADMP to address this growth. This update primarily recommended additional structural facilities in the northern portion of the City of Peoria.

The District has entered an Intergovernmental Agreement with the City of Glendale to conduct a second update to the ADMP. This update will review and consolidate recommendations of the Glendale/Peoria ADMP, Maryvale ADMP, and Glendale Stormwater Master Plan.

Status:

The original ADMP was completed in 1987. Since then, parts of the study area have been updated. Read the description above for more information.
