Update: September 2017. FEMA Risk MAP Guidance Updates

FEMA Risk MAP Guidance Updates

The Federal Emergency Management Agency (FEMA) maintains guidelines and standards to support the Risk Mapping, Assessment and Planning (Risk MAP) Program. These guidelines and standards define the implementation of the statutory and regulatory requirements for the National Flood Insurance Program (NFIP). These also guide the development of Flood Risk Projects, processing of Letters of Map Change (LOMCs) and related Risk MAP activities. More information is available at FEMA.gov.
FEMA maintains the Risk MAP guidelines and standards and issues updates on an annual basis each November.  For the 2017 Annual cycle, a Public Review for standards was held in August. FEMA is now initiating a review of all guidance, technical references and other resources.
This annual update includes routine maintenance and completion of the transformation of legacy guidelines and specifications to produce new guidance documents that align with the current structure of the Risk MAP Program.  In additional to these updates, there are several more significant changes that FEMA plans to implement that include:
  • establishing guidance for Base Level Engineering (BLE)
  • clarifying how submitters can use Light Detection and Ranging (LiDAR) or other elevation data for Letters of Map Amendment (LOMAs)
  • updating Flood Risk Product (FRP) requirements based on feedback from FRP users and stakeholders in the Fall of 2016
  • updating coastal standards to consolidate the definition of the V-Zone for coastal flood risk
Listed below are the guidance, technical reference, and other documents that are being updated for the 2017 Annual (Fall) cycle. If you are interested in reviewing any of the documents listed below, you can access the documents through the Risk Management Directorate SharePoint site and should provide comment through SharePoint if you are a mapping partner who has SharePoint access.  For stakeholders who do not have SharePoint access, email FEMA.GS@riskmapcds.com to request the documents that you wish to review.
FEMA recognizes that many stakeholders have been impacted by the recent hurricanes and other events.  If you feel like you need more time to review any of these materials, please email FEMA.GS@riskmapcds.com.
Comments received by October 16, 2017 will be considered for incorporation.
