Ashokan watershed maps

I received two emails about the Ashokan Watershed Stream Management Program

 Preliminary FEMA Flood Maps for the Ashokan Watershed are available for review on the Ashokan Watershed Stream Management Program (AWSMP) website: www.ashokanstreams.org. These maps developed by FEMA contractors utilize the most up-to-date technology to determine the watershed’s hydraulics, hydrology, as well as topographic features and elevations. The maps are more accurate than current floodplain maps, which were adopted in the 1980s. Municipal officials, real estate professionals, home and business owners, and many others, can utilize these maps to help determine the level of flood risk a particular structure or development may be exposed to near the floodplain. Once adopted, these maps and other information will be used to determine flood insurance rates and requirements for property owners in the floodplain.

New FEMA Levee Mapping Procedures FEMA Finalized Analysis and Mapping Procedures for Non-Accredited Levees The Federal Emergency Management Agency (FEMA), today, released its updated procedures for analyzing and mapping flood hazards in the vicinity of non-accredited levee systems. These updated procedures are a part of an on-going effort to reform the National Flood Insurance Program (NFIP). To review the final approach document, visit:
