Steps to Obtaining a Floodplain Use Permit
Any improvements to land, including construction of a building, adding fill or grading, and installing walls or fencing, can adversely affect the natural flow of water in a floodplain or watercourse.
If a property owner within Maricopa County wishes to perform construction or other improvements to property located within a delineated floodplain, a Floodplain Use Permit is required.
The Flood Control District enforces the Floodplain Regulations for Maricopa County, which regulate the construction of buildings and other improvements within designated floodplains to alleviate the upstream or downstream impacts.
When required, the Flood Control District reviews each permit application to ensure it complies with the Floodplain Regulations.
For more information, please go to the Floodplain Management section of this Web site.
Please refer to the Floodplain Directory of Documents for a compilation of Ordinances, Codes, Substantive Policy Statements, References and Resources that may be of use in the preparation of your floodplain use permit submittal documents. This list will be updated on an as-needed and regular basis.
To help you complete the application, the District has provided a detailed submittal checklist to guide you through what is required to be included with the application. The checklist is used in conjunction with the Floodplain Regulations and the Fee Schedule, which is included in the regulations as Appendix A.
Should you have any questions or need assistance throughout the application process please contact our Development Services office by phone at (602) 506-2419 or email at email@example.com.
An applicant may receive a clarification from the District of its interpretation or application of a statute, ordinance, regulation, executive order, delegation agreement or authorized substantive policy statement as provided in A.R.S. Section 48-3649.
