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. The Advisory LiMWA is intended to serve as the best available data for understanding coastal flood hazard risk and the elevations that communities should build to in order to protect themselves from future coastal flood events. Areas seaward of the LiMWA are subject to waves greater than 1.5 ft but less than 3 ft. Post-disaster building inspections and scientific studies have shown that waves greater than 1.5 ft are sufficient to induce structural damage to many National Flood Insurance Program compliant structures on shallow or solid wall foundations. The FEMA Coastal Construction Manual, American Society of Civil Engineers, and 2012 International Residential Building Code recommend Zone VE construction practices inside of the LiMWA. As part of the long term recovery effort, the Advisory LiMWA is a tool for Federal, State, and local officials, building officials, builders and architects, insurance professionals, and property owners to make informed decisions during rebuilding and to mitigate losses from future flood events, safeguard lives, and protect the private and public investment in rebuilding.

This advisory data was disseminated by FEMA. FIPS Pub 199 Standard Technical Controls This product is not be used as information to support regulatory floodplain designation or insurance ratings. Use of data is to provide the FEMA with guidance to disseminate to communities rebuilding after Hurricane Maria. The advisory elevations do not include freeboard and/or any additional safety factor to account for potential future increases of the coastal flood hazard due to sea level rise. Advisory mapping information was not adjusted to provide a seamless tie to any existing hazard Flood Insurance Study (FIS) mapping in adjacent areas.

The purpose of this product is to provide elevation guidance for rebuilding, not information to support regulatory floodplain designation or insurance ratings. As such, FEMA specified that the data be produced to provide simpler representative elevations than typical Flood Insurance Rate Maps (FIRMs) to promote ease of use. Detail has been removed from the linework, and narrow and/or small areas, generally under 400 ft in width or 160,000 sq ft in area, were eliminated to promote cartographic simplicity. A visual inspection of attribute tables was conducted to ensure that all necessary attribute fields were populated according to the received guidance. A GIS-based review was performed to ensure that the correct geographic attributes applied to the proper features, and that features were correctly located relative to each other. Data were not subjected to any statistical checks for accuracy. The Advisory LiMWA was developed from base data fully consistent with accuracy standards presented within FEMA’s Guidelines and Specifications for Flood Hazard Mapping Partners. Point elevations at transects are derived from the wave overland model and the line work between transects follows topographical and landuse information. The delineation is subject to the accuracy constraints of those data, and as with any engineering analysis of this type, variation is possible. feet -9999 The Advisory LiMWA was developed from base data fully consistent with accuracy standards presented within FEMA’s Guidelines and Specifications for Flood Hazard Mapping Partners.

In between transects topographical and landuse information were applied while interpolating the results from one transect to the next. The 1-percent LiMWA lines were tied to the boundary of the X zone, or Runup/PFD VE zone. 2018-02-06 Dewberry Consultants, LLC 703-849-0100 8401 Arlington Blvd Fairfax VA 22031 US 306 LiMWA_1PCT Feature class containing information associated with the dataset FEMA Feature Class 306 FID FID OID 4 0 0 Internal feature number.
