Mission Statement: The mission of the Flood Control District and Floodplain Administration of Santa Cruz County is to provide flood hazard identification, regulation, remediation, and education to the people in Santa Cruz County so that they can reduce their risks of injury, death, and property damage due to flooding while enjoying the natural and beneficial values served by floodplain's.

Division Goals & Objectives: To minimize flood and erosion damages for all county residents, property and infrastructure through a variety of flood control and natural resource management activities.

As a public service, the Santa Cruz County Flood Control District will provide the following information upon request:

  • We have several handouts available of the requirements and procedures for development within all flood prone areas within unincorporated Santa Cruz County and the City of Nogales, Arizona.
  • Review and investigation of drainage complaints regarding activities within the floodplain, such as filling, construction, or the alteration, diversion, or obstruction of the flow of water.
  • Provide maps of properties showing the location of floodplains on the property, both current and past FEMA Special Flood Hazard Areas and locally regulatory floodplains, and providing the topography on the property with a 2 foot contour interval.
  • Provide, via a Site Review, advice on potential ways of reducing or preventing flooding and flood related damages to private Property.
