Project Description:

The Flood Control District of Maricopa County (FCD), in partnership with the City of Phoenix, City of Glendale and Town of Cave Creek, is conducting an Area Drainage Master Study & Plan (ADMS/P) in the Adobe Dam, Desert Hills and Apache Wash Watersheds. This study will update the 2004 Adobe Dam/Desert Hills ADMP while also including the Apache Wash Watershed to the east.

In the last ten years, homes and infrastructure have been damaged from flooding. A study of this area was originally completed in 2004. Development has made significant changes to the watershed. This update will have fifteen more years of data and flooding events to assist modeling. Newer and more accurate technology is available to identify existing flooding hazards and risks in the area.
