NDOT’s Stormwater Planning Team has prepared a map showing NDOT’s prioritization of areas in the state based on potential impacts to surface waters. Priority 1 areas have the highest potential impact to water quality. Priority 2 areas have a moderate potential impact to water quality. Priority 3 areas have the lowest potential impact to water quality and consist of all areas that are not Priority 1 or Priority 2.
