Service Description: This map service was created to support the National Oceanic and Atmospheric Administration (NOAA) Office for Coastal Management’s (OCM) Coastal Flood Exposure Mapper. The purpose of the online mapping tool is to provide coastal managers, planners, and stakeholders a preliminary look at exposures to coastal flooding hazards. The Mapper is a screening-level tool that uses nationally consistent data sets and analyses. Data and maps provided can be used at several scales to help communities initiate resilience planning efforts. Currently the extent of this map service and the Coastal Flood Exposure Mapper is limited to U.S. coastal counties along the Gulf of Mexico and Atlantic Ocean. The purpose of this map service is to depict areas most prone to coastal flood hazards by representing the number of coastal flood hazard zones that overlay an area. Creation of data displayed in this map service included analyses of the following ten flood hazard zones: Federal Emergency Management Agency (FEMA) V zones, FEMA A zones, FEMA shaded X zones, NOAA OCM Flood Frequency zones, NOAA OCM potential sea level rise inundation extents for 1 foot, 2 feet, and 3 feet above current Mean Higher High Water (MHHW), and Sea, Lake, and Overland Surges from Hurricanes (SLOSH) Maximum of the Maximums (MOMs) for categories 1,2 and 3 hurricanes. This is a cached map service. Tiles have been cached down to Level ID 15 (1:18,055). The dataset should be used only as a screening-level tool for management decisions. As with all remotely sensed data, all features should be verified with a site visit. The dataset is provided "as is," without warranty to its performance, merchantable state, or fitness for any particular purpose. The entire risk associated with the results and performance of this dataset is assumed by the user. This dataset should be used strictly as a planning reference and not for navigation, permitting, or other legal purposes.
