Description: Location and attributes for flood insurance risk zones on the FIRM. The National Flood Hazard Layer (NFHL) data incorporates all Flood Insurance Rate Map (FIRM) databases published by the Federal Emergency Management Agency (FEMA), and any Letters of Map Revision (LOMRs) that have been issued against those databases since their publication date. It is updated on a monthly basis. The FIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper FIRMs. The FIRM Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The FIRM Database is derived from Flood Insurance Studies (FISs), previously published FIRMs, flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by FEMA. The NFHL is available as State or US Territory data sets. Each State or Territory data set consists of all FIRM Databases and corresponding LOMRs available on the publication date of the data set. The specification for the horizontal control of FIRM Databases is consistent with those required for mapping at a scale of 1:12,000. This file is georeferenced to the Earth's surface using the Geographic Coordinate System (GCS) and North American Datum of 1983.NFHL Layer Downloaded 08092018 from FEMA website and reprojected to NAD 1983 State Plane feet coordinate system( https://msc.fema.gov/portal/advanceSearch#searchresultsanchor) .

Description: In this project, the University of Florida (UF) GeoPlan Center is providing Geographic Information System (GIS) technical assistance for creating updated Florida statewide Ultimate Design Wind Speed line maps for the 8th Edition (2023) update to the Florida Building Code (FBC). Updates to Figures: 1609.3(1), 1609.3(2), 1609.3(3) and 1609.3(4) will be based on the standards set forth in Chapter 26 of the American Society of Civil Engineers (ASCE), the Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE/SEI 7-22). In addition, the GeoPlan Center shall provide GIS technical assistance in preparing local wind speed line maps for each building code jurisdiction that is impacted and dissected by the wind speed contours as updated and depicted in the draft Florida Building Code, 8th Edition (2023) Figures 1609.3(1-4) Risk Categories I - IV Buildings and Structures. This final report addresses details of the project’s progress to date on each task listed in the scope of work. In summary, Task 1 is complete, and Task 2 is complete.Notes:1.Values are nominal design 3-second gust wind speeds in miles per hour (m/s) at 33 ft (10m) above ground for Exposure C Category.2.Linear interpolation between contours. Point values are provided to aid with interpolation.3.Islands, coastal areas, and land boundaries outside the last contour shall use the last wind speed contour.4.Mountainous terrain, gorges, ocean promontories, and special wind regions shall be examined for unusual wind conditions.5.Wind speeds correspond to approximately a 3% probability of exceedance in 50 years (Annual Exceedance Probability = 0.000588, MRI = 1700 Years).6.Location-specific basic wind speeds shall be permitted to be determined using www.atcouncil.org/windspeed.Ultimate Design Wind Speeds, Vult, For Risk Categories I-IV Buildings and Other Structureshttps://ufl.maps.arcgis.com/apps/mapviewer/index.html?webmap=3a5d5dd7d44744eeb9537b76534a72a9
