Massoud Rezakhani Consulting (MRC) LLC provides flood hazard analysis and mitigation solutions for both public and private-sector clients. Our expertise covers flood hazard mapping, disaster response and mitigation services, land planning and development, and coastal engineering.

MRC LLC has over 50 years of experience, including 30 years of experience working directly with the Federal Emergency Management Agency (FEMA) under the National Flood Insurance Program (NFIP). Our firm has helped develop several of FEMA’s current policies and regulations. This allows us to quickly and efficiently evaluate existing FEMA floodplain designations, negotiate with federal, state, and local agencies to get them reclassified where possible, and obtain the necessary permits to ensure successful completion of a project.

By analyzing the FEMA floodplain designation areas at a more detailed level, MRC LLC is able to reclaim the use of previously unusable land. We are often able to reduce the floodplain areas and provide flood mitigation plans for the remaining areas, such as the design of detention basins, floodwalls, road crossings, and channel sizing.

Headquartered in Scottsdale, Arizona, MRC LLC has satellite offices in California, and Hawaii. Regardless of project size, location, or turnaround time, we have the resources to meet your needs.


MRC LLC teams up with select water resources engineering partners on large-scale or regional projects. Acting as the project lead, we work with other senior-level consultants who are registered professional engineers with graduate degrees and experience in water resources planning and engineering. Our primary partners are listed below:

  • Dewberry
  • R.M. Towill, Inc.
  • HDR, Inc.
  • Group 70 International
