FEMA Risk MAP Guidance and Technical Reference 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 www.fema.gov/guidelines-and-standards-flood-risk-analysis-and-mapping.
FEMA maintains the Risk MAP guidelines and standards and issues updates on an annual basis each November. For the 2019 Annual cycle, a Public Review for standards was held in July through August. FEMA is now initiating a review of all guidance, technical references and other resources.
As part of this policy update cycle, FEMA performed routine maintenance and smaller updates driven by specific requests or issues identified. In addition to these smaller updates, there are several significant changes that include:
- New strategies for modernizing legacy maps: It is a priority for the mapping program to fully modernize the map inventory. However, there are unique challenges with many of these remaining areas. FEMA is refining guidance for the Discovery process to streamline simpler projects that are modernizing legacy maps.
- Automate map products: FEMA has systems in place that can automatically produce high quality Flood Insurance Rate Map (FIRM) images from the National Flood Hazard Layer (NFHL). However, legacy processes still result in significant time and money spent on manual cartography to create the FIRM deliverables. This activity will mandate that future FIRM images be produced using an automated tool to reduce cost. This requirement will apply to new projects starting in FY20 and not required for work in the pipeline. The tool and the implementation details will be developed over the next year.
- Removing floodways during a map update: FEMA is converting Standard Identification Number (SID) to a program standard. This ensures that HQ and the Regional office are involved in complicated decisions related to existing floodways during an update.
- Financial Tracking Improvements: FEMA is formalizing processes for tracking regional cost allocations and status of funds for flood map projects including studies and other investments.
Listed below are the guidance, technical reference, and other documents that are being updated for the current annual 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.
Comments received by September 30th, 2019 will be considered for incorporation.
