Description: The Streams file is intended to serve as the location of flooding source where the ABFEs were analyzed and further used in the Hydraulic analysis.
Description: The CrossSections are intended to serve the location on the flooding source to calculate the water surface elevations for 10%, 4%, 2%, 1%, 1%, and 0.2% flood events.
Description: The Federal Emergency Management Agency (FEMA) has developed the Advisory Limit of the 1% Flood Hazard Area to provide a geospatial limit to the Advisory Base Flood Elevations as well as an updated representation the 1% annual chance flood hazard area.
Description: The Federal Emergency Management Agency (FEMA) has developed the Advisory Flood Zones. They provide full geospatial representation of the coastal and riverine Advisory Base Flood Elevations (1% annual chance coastal flood hazard), including both storm surge and wave components. FEMA is providing an advisory floodway to provide a geospatial limit of the channel of rivers or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than the designated height. FEMA has developed the Coastal A Zone to approximate the extent of breaking waves less than 3 ft and equal to and greater than 1.5 ft in height for the 1-Percent-Annual-Chance flood events

Description: The Federal Emergency Management Agency (FEMA) has developed the Advisory Limit of Moderate Wave Action (LiMWA) to approximate the landward limit of the 1.5 foot breaking wave. The LiMWA defines the landward boundary of the Coastal A Zone Area, or the Area of Moderate Wave Action (MOWA ). Wave model output was reviewed and analyzed for the delineation of the LiMWA line.
