Flood maps are commonly developed based on historic flood flows. Yet they are used for siting new development that will be in place for 100 years. Flood elevations during the life of development is likely to increase due to development in the watershed and climate change.
The Federal Flood Risk Management Standard (FFRMS) is a flood standard, established in Executive Order 136903, to increase community resilience to flooding. FEMA has developed interim policy related to the implementation of FFRMS. The interim policy requires structures in the FEMA SFHA to be elevated above the Base Flood Elevation. The amount of additional elevation required is dependent on whether the structure is a critical or non-critical facility.
Maryland has conducted an analysis of the number of structures that are within the BFE +1, 2 and 3 foot flood extents. The objective of their analysis was to determine the number of structures at risk as a result of accelerated sea level rise and/or increased rainfall intensity.
Join us for a discussion of elevation requirements associated with implementation of the Federal Flood Risk Management Standard and state efforts to determine the number of structures at risk due future conditions associated with sea level rise and increased rainfall intensity.
