Floodplain Use Permits are issued by the Flood Control District of Maricopa County for development in a floodplain, including extraction of sand and gravel or other material. Even if you may not need a building permit for your project, if you are doing work within a designated floodplain, you are required to obtain a Floodplain Use Permit before you build, grade, fill, install any type of wall or fencing, or perform any other man-made change to the property.
The Flood Control District requires a Right-of-Way Use Permit be obtained prior to any development or access requested on property that the District owns or has easements over and/or on structures we maintain.
Applications for subdivision plats, zoning and other processes, and building permits for unincorporated Maricopa County are handled through the Department of Planning and Development. Cities and towns in incorporated Maricopa County process their own building permits for development within the city/town limits.
