The Wetlands Overlay District shall consist of coastal wetlands, defined as salt marshes bordering on tidal waters, and freshwater wetlands, defined as those areas of 1/2 acre or greater, that are inundated or saturated with surface and/or ground water at a frequency or duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. The boundaries of the Wetlands Overlay District are generally shown as Coastal Wetlands, Freshwater Wetlands or Hydric Soils on that map titled "Wetlands Area Map" (Town of Barrington, Rhode Island Comprehensive Community Plan) and filed at the office of the Building Official. In the event that there is a conflict in the boundary of this District between the written definition above and the map, the written definition shall prevail.
