The easiest way to determine if your property is in the Critical Area is to view the M-NCPPC PGAtlas website. Once on the site, go to Advance Mapping, select the binocular icon and enter your street address. Once your address information displays, select the magnifying glass to zoom in on the map to your property. Once your property displays, go to the icons on the right side and select the map layer icon. Once the layer list displays, select the drop down button next to zoning. Under the zoning layer, check off the box for Chesapeake Bay Critical Area Overlay (2015). If you do not have access to the internet, you can review detailed maps at the Planning Information Services counter in the Lower Level of the County Administration Building, 14741 Governor Oden Bowie Drive, Upper Marlboro, Maryland.
