Contact other cities directly for floodplain management in their jurisdiction.
Please contact the District at 602-506-2419 for more information regarding the process and requirements for submission of a Letter of Map Change (LOMC) request to the Federal Emergency Management Agency (FEMA). A LOMC is for a formal determination of the property’s location and/or elevation relative to the Special Flood Hazard Area (SFHA).
The District may have a record of the Elevation Certificate if the structure is located in the unincorporated areas of Maricopa County and if one was required when the structure was built. Residences constructed prior to being mapped into a high-risk flood zone typically may not have an Elevation Certificate on file. Please contact the District at 602-506-2419.
If you are not located in the unincorporated areas of Maricopa County, contact the jurisdiction in which the structure is located to inquire about record of the Elevation Certificate.
For new or existing structures that were recently identified as being in a floodplain, an Elevation Certificate is typically completed by a registered land surveyor or engineer. However a homeowner or representative may complete the Elevation Certificate for Federal Emergency Management Agency (FEMA) Zones AO and A without a base flood elevation.
An Elevation Certificate can range from $400 - $1,000 depending on the complexity of the job. Please contact a qualified land surveyor or engineer to prepare the Elevation Certificate.
The District will provide a copy of an Elevation Certificate at no cost if we have a one on record. Note: the Elevation Certificate is the responsibility of the owner who initially builds the structure and it is used to show compliance with the approved site plan and to provide documentation for obtaining flood insurance.
Please complete the Flood Hazard Information Request so that we can send you a detailed report about your property. You can also view the Floodplain Viewer to assist with determining if your property is located in a 100-year floodplain.
If your property is located in a jurisdiction that the District does not perform floodplain management duties for, you may be referred to the appropriate jurisdiction for more information.
