Project Type: Study
The Metro Phoenix Area Drainage Master Plan Update (Metro ADMPU) is underway to develop and recommend strategies to reduce flood hazards and protect public safety in a study area located within the cities of Phoenix, Scottsdale and Tempe. The plan will update and refine the findings of the original Metro Phoenix Area Drainage Master Plan completed in 2008. This update will use newer modeling techniques and updated mapping to capture recent land use changes and better identify the extent of drainage and flooding problems within the study area. The Cities and District will use the results of the drainage and flooding problem identification to refine the existing proposed solutions and identify potential new solutions to better define and budget future drainage improvement projects.
The Metro ADMP Update will:
- Create a database of known flooding and drainage problems
- Develop state-of-the-art models using updated technology and new aerial mapping
- Assess flooding hazard and previously proposed solutions
- Restudy the metro Phoenix floodplains
- Prepare a plan to provide potential solutions for flood-prone areas
The Metro ADMPU study area is located mostly within the City of Phoenix; however, it also includes portions of the Cities of Scottsdale and Tempe along its eastern end. The study area is approximately 90 square miles and predominately covers the central part of Phoenix that is located south of the Arizona Canal, north of the Salt River, between Interstate 17 and the Papago Buttes.

The second study phase is currently underway and includes the following tasks:
- Continue data collection and field reconnaissance of flood prone areas and existing infrastructure
- Develop a detailed rainfall-runoff computer model of existing hydrologic conditions, incorporating collected data on existing storm drain systems and other infrastructure
- Identify and analyze flooding hazards and risks
- Continue public engagement and stakeholder coordination
First Phase Completed
Posted On: 4/7/2021 11:36:00 AM
The study began in November 2019 and the team has finished the first phase. This phase included the following tasks:
- Compile a comprehensive database of critical project information from project partners and stakeholders, including known flooding and drainage problems and existing infrastructure
- Develop a base rainfall-runoff computer model of existing hydrologic conditions
- Coordinate involvement of local agencies and groups
There are no public meetings scheduled.
