Project Description:

Study results and proposed alternatives are available to view.

 

The Flood Control District of Maricopa County (FCD), in partnership with the City of Phoenix, City of Glendale, and Town of Cave Creek, is working on an important study to better understand and reduce flooding in the Adobe Dam, Desert Hills, and Apache Wash watersheds.

This effort is called the Area Drainage Master Plan (ADMP)—an update to a previous plan completed in 2004. This time, it includes a new area, the Apache Wash Watershed, located to the east.

Why This Study Matters

Flooding affects people, property, roads, and daily life. As our communities grow and change, it’s essential to make sure our flood protection plans keep up. The goal of the ADMP is simple: reduce flood risk for current and future residents.

To do that, we’re:

  • Identifying current flood hazards and how severe they are
  • Working with local residents, HOAs, and city leaders to hear concerns and gather feedback
  • Developing possible solutions to better manage stormwater and prevent damage

How This Benefits You

When the plan is complete, communities across this area will gain:

  • A clearer understanding of flood risks in their neighborhood
  • Updated tools and data that help us make smarter decisions about future growth
  • A list of potential projects and solutions to reduce flood damage
  • Opportunities for residents to shape the plan and give input on proposed options

What We've Done So Far

Over the past year, our team has been busy learning everything we can about how water moves through the area:

  • Monitoring current conditions and collecting field data
  • Surveying stakeholders to learn from real experiences with flooding
  • Comparing today’s watershed to past studies to see what’s changed
  • Creating a stormwater model to test solutions that could help

Feedback Needed: Potential Solutions are Available
Posted On: 4/24/2025 8:53:41 AM

We’ve made significant progress on the Adobe Dam, Desert Hills, and Apache Wash Watersheds ADMP. Here's where we are now:

  • Flood hazard areas have been identified. Using up-to-date data and fieldwork, we now have a clear understanding of where flooding is most likely to occur within the study area.
  • Modeling is complete. Our engineers have built detailed stormwater models to simulate how water flows through the region—now and in the future.
  • We've met with key partners. Cities, towns, HOAs, and other stakeholders have helped us explore structural options to reduce flood risk.
  • Potential solutions have been developed. We’ve created a set of possible projects and strategies that could help reduce flooding impacts in specific neighborhoods.

Now, we want to hear from you.

You know your neighborhood best. We're asking residents to review the proposed options and share which ones you think make sense for your area.
