The Federal Emergency Management Agency (FEMA) is working with State agencies, regional entities, tribes, and communities to update the flood hazard risk information and produce new digital Flood Insurance Rate Maps (FIRMs). Per FEMA’s new Expanded Appeals Process, studies and Physical Map Revisions (PMRs) for which Proposed Flood Elevation Determination Notices have yet to be published in the Federal Register and those for which preliminary FIRMs and Flood Insurance Study (FIS) reports will be issued on or after December 1, 2011, will be posted to county-specific pages on this site. Studies processed using the appeal initiation process in effect prior to December 1, 2011, will not be restarted. To reference studies that are already effective, please visit the Map Service Center.
To determine the status of Preliminary Map products and location of Revised Flood Hazard Maps for Arizona counties interested parties should:
- Click on the county name from the Counties listed in the left column of this page to view preliminary FIRMs or Letters of Map Revision (LOMR), where applicable.
- Visit the Community Map Repository in the community of interest to view paper copies of the FIRMs and the accompanying FIS reports. The Community Map Repository is the local office in a participating community where the NFIP flood hazard maps, FIS reports, and related products (e.g., Letters of Map Change) are kept for local use and viewing by citizens. The addresses of the Community Map Repositories are provided on the FIRM indexes; you may also obtain information on the Community Map Repositories by contacting the FEMA Map Information Exchange (FMIX), toll free, at 1-877-FEMA MAP (1-877-336-2627).

County:
Cochise
State:
Arizona
Description:
BakerAECOM completed the mapping of various Zone A streams in and around Cities of Benson and Sierra Vista, and Cochise County (Unincorporated Areas). This project is currently delayed as FEMA evaluates the use of the 2009 version of Flo-2D for the Richland Ranchettes subdivision
| | Town of Clifton Physical Map Revision |
Study Type:
Physical Map Revision
County:

The Provisionally Accredited Levee (PAL) agreement for the Clifton levee in Greenlee County, Arizona expired on May 25, 2009. In accordance with Title 44, Chapter 1, Section 65.10 of the Code of Federal Regulations (44 CFR 65.10), it is the responsibility of the community or other party seeking recognition of a levee system, to provide the data and documentation defined and outlined in 44 CFR 65.10. FEMA will review submitted data, and new hydrologic and hydraulic analyses, and if the data is acceptable, levees will be mapped as accredited.
| | La Paz County Physical Map Revision |
Study Type:
Physical Map Revision
County:
La Paz
State:
Arizona
Description:
BakerAECOM conducted a scoping meeting on November 18, 2009 and is updating the behind levee flood hazard analyses to map the area previouslly depicted as provisionally accredited on the August 28, 2008 effective countywide Digital Flood Insurance Rate Map (DFIRM) as accredited. BakerAECOM is also updating the special flood hazard areas in the vicinty of Cibola. This revision includes 3 square miles of 2-dimensional hydraulic modeling of flooding originating in Crazy Woman Wash, Secondary Wash, and other washes in the vicinity of Cibola.
| | Maricopa Countywide Digital Flood Insurance Rate Map |
Study Type:
Countywide
County:
Maricopa
State:
Arizona
Description:
The Maricopa County DFIRM project that began in the summer of 2008 will be effective on October 16, 2013. The Letters of Final Determination (LFD) were mailed to community CEO’s on April 16, 2013, and this date is the start date for the adoption and compliance period. Over the course of the project, these key tasks were completed:
- Revised over 330 FIRM Panels
- Created 23 Flood Insurance Study Volumes
- Revised panelization scheme for Maricopa County (See the Tables in the Project Documents section of this page for the 2005 FIRM panel translation to the 2013 FIRM panel numbers)
- Vertical datum conversion from National Geodetic Vertical Datum of 1929 to North American Vertical Datum of 1988
- Incorporated over 125 Letters of Map Revision
- Approximately 330 stream miles receiving new detailed study either from Best Available Data Letters or North Scottsdale Restudy
- Areas protected by accredited levees are depicted on maps
- Adjusted special flood hazard areas (SFHA) where non-levee embankments (i.e. roads, railroad grades) impact the SFHA
| | Physical Map Revision for Levee Analysis |
Study Type:
Physical Map Revision
County:
Maricopa
State:
Arizona
Description:
The Provisionally Accredited Levee (PAL) agreements for the levees in Maricopa County, Arizona expire on June 25, 2011. In accordance with Title 44, Chapter 1, Section 65.10 of the Code of Federal Regulations (44 CFR 65.10), it is the responsibility of the community or other party seeking recognition of a levee system, to provide the data and documentation defined and outlined in 44 CFR 65.10. BakerAECOM will review submitted data, and new hydrologic and hydraulic analyses, and if the data is acceptable, levees will be mapped as accredited on the Countywide Digital Flood Insurance Rate Map (DFIRM) for Maricopa County scheduled to become effective summer 2012.
The Federal Emergency Management Agency's studies for mapping flood hazards behind levee systems that cannot be recognized as providing protection from the base (1-percent-annual-chance) flood will not be finalized until the new set of guidelines for mapping flood hazards behind non-accredited levees are developed. These levees will be mapped on the Countywide DFIRM with a PAL note.
| | Mohave Arizona Physical Map Revision |
Study Type:
Physical Map Revision
County:
Mohave
State:
Arizona
Description:
BakerAECOM conducted a scoping meeting on November 19, 2009. There is currently non-accredited levees affecting Mohave County. The Federal Emergency Management Agency (FEMA) is currenlty in the process of developing new procedures for evaluating and mapping flood risk behind non-accredited levees. When the new procedures are approved for FEMA Regions to begin implementing, FEMA Region IX will contact the affected communities to discuss the non-accredted levee evaluation process.
FEMA Region IX has moved forward with study affecting the Colorado River. FEMA issued the following panels for the Physical Map Revision: 0415CIND1B, 0415CIND2B, 04015C4761H, 04015C4763H, 04015C5050H, 04015C5052H, 04015C5054H, 04015C5075H, 04015C5350H, 04015C5375H, 04015C5650H, and 04015C5675H.
The final FIS Report and map products for this project can be obtained from the Product Catalog on the Federal Emergency Management Agency's (FEMA's) Map Service Center web site.

The Willow Creek levee re-mapping project is delayed as FEMA evaluates its guidelines for mapping behind non-accredited levees.
FEMA is currently updating its guidelines for mapping flood hazards behind levee systems that cannot be recognized as providing protection from the base flood. The new set of guidelines for mapping flood hazards behind non-accredited levees are planned to be developed by the end of this year. As a result, FEMA will not issue a determination letter finalizing the revised Flood Insurance Rate Map (FIRM) panels and Flood Insurance Study (FIS) Report for the Willow Creek levee until updated FEMA guidelines are available.
