GIS NDOT Stormwater Asset Map (SAM)

Some assets such as pipes, drop inlets, manholes and basins are not visible when viewing larger areas. Zoom in to smaller scale and these assets will become visible. 

The NDOT 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.
