Each report component is first presented with a general description related to the specific component and then a unique analysis for the property of interest.
Local municipalities (cities/counties) often divide their communities into different areas or zones. Each zone category typically dictates what type of development can occur. For example, a zone might be designated as single use where residential type buildings can be constructed. The zone designation might also indicate the lot size or the building scale that is allowed at that location.
Topography and Terrain
No Flood Florida relies on the most up-to-date digital terrain information that is derived from LiDAR technology. For a given property of interest, we will display the digital terrain model along with 1-ft contours to help better understand the slope of the land.
National Wetland and Flowline Features
Wetland and flowline data are incorporated into the Land Due Diligence Report to help better understand potential hazards when developing a piece of land. Often, wetlands are protected from development pressures.
FEMA Effective Floodplains
The current FEMA Effective Floodplain maps are used to help determine development capabilities and potential issues with mitigation. Additionally, the presence of the high-risk floodplain on a property could trigger flood insurance requirements. Below is a brief review of the different flood zone designations:
- High Risk Zones
- Zone A – These areas are similar to the 100-year floodplain, with the exception of not having an engineering model establishing the Base Flood Elevation. Homes in these areas are typically required to purchase flood insurance.
- Zone AE – These areas are subject to inundation by the 100-year storm event. Base Flood Elevations (BFEs) derived from detailed hydraulic analyses are established. Mandatory flood insurance purchase requirements and floodplain management standards apply. No Flood Florida further breaks down the Zone AE floodplains into AE, LEVEL POOL and AE, RIVERINE. An AE, LEVEL POOL flood zone indicates a none-flowing system, while the AE, RIVERINE designation defines flood zones that are associated with flowing systems.
- Zone VE – These areas are subject to inundation by the 100-year storm event with additional hazards due to storm-induced velocity wave action. Base Flood Elevations (BFEs) derived from detailed hydraulic analyses are established. Mandatory flood insurance purchase requirements and floodplain management standards apply.
- Moderate Risk Zones
- Zone X, shaded – These areas are subject to inundation during what is called the 500-year storm. The 500-year storm has a 0.2 % chance of happening in any given year. This happens less often than the 100-year storm. Homes in these areas typically are not required to purchase flood insurance. No Flood Florida defines this zone as X, 0.2 PCT ANNUAL CHANCE FLOOD HAZARD with a BFE of None.
- Low Risk Zones
- Zone X – The areas of minimal flood hazard, which are the areas outside the SFHA and higher than the elevation of the 0.2-percent-annual-chance flood (500 year flood), are labeled Zone C or Zone X (unshaded). No Flood Florida defines this zone as X, AREA OF MINIMAL FLOOD HAZARD with a BFE of None.
Soils data were downloaded from the United States Department of Agriculture (USDA) Soil Survey website. Through additional processing, No Flood Florida is able to report on the hydrologic soil class, the frequency of flooding, and the ability of the surrounding soils to infiltrate water.
Landuse data are often produced by local/state agencies. These geospatial features convey the type of landuse for a given area. Some examples might be Residential, Industrial, Commercial, etc.
Often, local communities and governments provide general coverages for utilities that No Flood Florida can visualize on a map. The utility coverages often define various municipality services like water and sewer.
