  • Help with borrower requests such as through the flood map amendment process
  • Working with FEMA and community officials to identify flood mapping issues

We understand that from time to time you may encounter conflicting flood zone information. As a service to you, we will recheck our work. You can start the "dispute" process either from (you'll need to have an account with us) or by calling our Client Services Department. Once the dispute is initiated, our team will pull together the relevant resources, and our Dispute Resolution Specialists will recheck each aspect of the determination for accuracy and contact you with the results. If you or your borrower has questions about the LOMA application process, we'd be happy to help. For FEMA guidance on LOMA applications, click here.

Due to the frequency of flood status changes, a portfolio of acquired or seasoned loans can rapidly become outdated, particularly during FEMA's current mapping initiative to update maps throughout the country. CoreLogic's flexible menu of portfolio review and maintenance services can help keep your portfolio in compliance.

  • Customized portfolio assessment. When a client acquires a new portfolio of loans, you may not know the level of flood data accuracy or the compliance status of those loans. In that case, it's wise to invest in a portfolio review and flood risk analysis. Our cost-effective, customizable menu of assessment options allows you to choose the level of analysis and reporting you need.
  • Fully guaranteed portfolio update. To give a client full confidence that your portfolio is compliant, we can review all properties in the portfolio, identify those that already have current flood zone determinations, and issue new, guaranteed determinations for the rest. Or, if necessary to meet the requirements of a portfolio sale, we can issue guaranteed CoreLogic determinations for the entire portfolio.

From loan closing through payoff, CoreLogic is an expert partner in flood risk management. We can build a customized servicing program to help our clients meet regulatory requirements, satisfy their investors and keep their business growing.

You can reach our Portfolio Services Department through our central number (844) 411-5578.

CoreLogic Continuously Tracks FEMA Map Changes

Flood hazard conditions are dynamic, and flood maps do not always reflect recent development or natural changes that may impact flood risk in areas. Therefore, flood maps must be periodically updated by FEMA to reflect changes to the floodplains that result from community growth, development, erosion, and other factors. A study conducted by the General Accounting Office during 2003-2004 revealed that 70% of the nation's flood maps were more than 10 years old, and that many current maps contained inaccurate flood data. These findings prompted FEMA to launch a multi-year, Presidential initiative supported by Congress.
