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.
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.
