Priority Planning Area Map

This map identifies areas near, or hydrologically connected to, tidal water bodies at increased risk of inundation under a 3.3-foot sea level rise scenario, projected to occur as soon as 2070. This map was produced by Broward County staff and represents the elevation of mean higher high water in 2070 based on the 2019 Southeast Florida Regional Climate Change Compact Unified Sea Level Rise Projection and 2007 LiDAR digital elevation model. The Priority Planning Areas are limited to the coastal communities with land east of the SFWMD's salinity control structures. A 40-inch sea level rise scenario projected from Mean Higher High Water (MHHW) at South Port Everglades tide station is equivalent to an elevation of 3.86 feet NAVD88. The feature class is a representation of this 40-inch sea level rise scenario on the 2007 LiDAR, with a pixel resolution of 50 feet. This map is used as the basis for assessing future flood risk as a function of land elevation and coastal water levels and thus aids in informing adaptation needs in the context of land use considerations. Areas within the PPA are most directly affected by the influence of sea level rise on surface flooding and groundwater levels; these impacts are most pronounced in coastal areas seaward of salinity control structures.
