Floodplain Easements in Prince George's County.
The Floodplain Easement Layer is a graphic representation of one of the various conservation easements in Prince George's County.. This layer is important when making long-range land use planning decisions, and also when on-site development activities occur. This layer is to be used as a tool by the Planning Department when analyzing and researching properties in Prince George's County. It is understood that this layer, for some time to come, will be incomplete, and, it may never be 100% complete simply because of the nature of easements and the fact that they can be established at different times in the process and through different means. The original easement data was recorded up to 2002, known in this layer as legacy data, when updates ceased until project continuation September 2010. The 100-year floodplain as delineated by the appropriate county agency and/or FEMA. A 100-year flood is one that has one chance in one hundred or a one percent (1%) chance of being equaled or exceeded in any given year. The 100-year floodplain applies mainly to water courses with a drainage area of 50 acres or greater. The delineation of a 100-year floodplain for development purposes considers the future development of the land within the drainage area; FEMA delineated floodplains do not. Floodplain easements are those areas delineated to ensure permanent protection of the 100-year floodplain considering future development within the drainage area.
