Which Permit Do You Need?

Floodplain Use Permit

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.

Right-of-Way Use Permit

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.

Additional Permits

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.

Are you installing a manufactured homes or factory-built building? You must also apply for an installation permit at the Arizona Department of Housing Manufactured Housing Division. Other permits, such as the Floodplain Use Permit, may be required prior to receiving the installation permit.

APPLYING FOR A VARIANCE

Generally, Variances may be granted only if special circumstances, such as size, shape, topography, location or surroundings of the property, would cause the strict application of the Regulations to deprive the property of privileges enjoyed by similar property in the floodplain.

Reasons for a Variance to Be Issued

Variances may be issued for the repair, rehabilitation, or restoration of structures listed in the National Register of Historic Places or the State Inventory of Historic Places, upon a determination that the proposed repair or rehabilitation will not preclude the structures' continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.

Variances shall only be issued upon showing that the use cannot perform its intended purpose unless it is located or carried out in close proximity to water. This includes only facilities defined in Section 205 of the Floodplain Regulations in the definition of "Functionally Dependent Use."

Revisions or modifications to the application for the building permit will be reviewed by the District and the applicant notified if the Floodplain Use Permit or Floodplain Clearance Review must be amended or a new application initiated.

Right of Way Use Permits

The Flood Control District of Maricopa County (District) requires a Right-of-Way use permit for any construction and/or access on District real property. The District has an on-line permit application process. To access the online application, register as a new user or sign in here. For assistance with online application and plan review see the User Guide. Review the requirements of the section in the User Guide on “File Size and Naming Conventions” prior to uploading plans for review.

How to determine whether or not a Right-of-Way permit is required

First:
Review the District’s Structures and Property Viewer and locate the subject property/project. Please note that property includes easements.

Second: Determine whether or not the project will require work on or adjacent to District property, access to District property, have connections to District projects, or will change access points or drainage to any District property and/or projects.
If so, contact the District ROW Specialist for a final determination of whether or not a permit will be required. 

Right-of-Way Application Process

Concept Plans: Typically, permit application begins with a conceptual plan. At the applicant's discretion, District staff will meet with the applicant to discuss any conceptual plans or scope and provide information on any FCD standards that may impact the design. There is no charge for this preliminary review of your plans, and we strongly encourage this meeting as it will help to reduce the number of review cycles that your plans might need.

Design Plan Approval: The applicant can upload plans and reports to the District for review. The District will review the plans and provide written comments, if there any deficiencies. Upon completion of the review, FCD will transmit the results of the review to the applicant. Revisions to the plans may be necessary. FCD will transmit a final plan approval letter to the applicant once the FCD receives revised plans that address FCD's concerns. Please note that written correspondence does not constitute authorization to begin construction activities within FCD's right-of-way, a Right-of-Way Use Permit is required.

Easement Requirements: For permanent installations on FCD owned Right-of-Way an easement from the FCD will generally be required. The applicant will also need to provide a map exhibit and legal description of the easement in 8 ½ inches by 11 inches recordable format. After approval of the map and legal, a public notice of the proposed easement will be advertised and the property posted, followed by easement valuation. The applicant will be responsible for all costs associated with an appraisal, if applicable. Applicant shall allow 4 to 6 weeks for FCD review.

Permit Issuance: FCD will issue a Right-of-Way Use Permit after any additional paperwork and information that is outlined in the Plan Approval letter is received, all fees have been paid and a bond has been secured. The permit is typically issued to General Contractor doing the work and normally requires preparation and approval of a Work Plan and Emergency Action Plan.

Construction and Inspection: During construction, District inspectors will visit the site and provide approvals for specified activities usually involving structures. The inspection requirements will be identified during a pre-construction meeting. Changes to the plans will require approval from the District and will follow a similar process as the Design Plan Approval which may require an addendum to the permit.

As-built and Close Out: Once the work is complete and approved by the inspectors, the District requires the submittal of as-built plans and QA/QC testing data.
