The Flood Control District of Maricopa County (FCD), in partnership with the City of Scottsdale and Town of Carefree, is conducting an Area Drainage Master Study (ADMS) in the Desert Mountain and surrounding area to identify known and potential flooding hazards. The project area is approximately 15 square mile and includes residential subdivisions, large lot residential development, commercial areas and undeveloped land. Specifically, the study area encompasses the communities of Desert Mountain, Carefree Ranch, Quail Ridge, Tonto Hills, and Carefree Shadows.

This study will be the first analysis of the flooding hazards in the Desert Mountain area. The study area has experienced flooding, erosion and sediment deposition, and over 20% of the land within the study is in a FEMA delineated floodplain. Some of these floodplain delineation studies were completed within the last ten years; however, some of the studies are over twenty years old. In the last twenty years, significant development has occurred in the study area, which likely affected the drainage characteristics and associated floodplains.

The primary purpose of this ADMS is to identify the flooding hazards based on existing conditions. This will be accomplished by technical evaluation and data collection using various methods and sources, such as hydrologic and hydraulic modeling, surveys, reviewing previous studies, and meeting with property owners and agencies. The results of the Desert Mountain ADMS will be used to determine if additional actions are needed to help protect property owners and development from flooding hazards. The results can also be used to guide future development and help plan drainage infrastructure and flood mitigation measures that are appropriate for the built and natural environment.
