2024 Critical Area
The purpose of the Chesapeake Bay Critical Area (CBCA) Remapping effort is to provide an updated critical area map for the Counties of Maryland. This layer has been approved and is the official Critical Area Boundary for Somerset County, Maryland (adopted June 2024).
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This data layer contains the new critical area boundary and corresponding designations derived from shoreline and wetlands digitized from 2016 aerial imagery and CIR. A 1000' buffer of the shoreline and wetlands generated the proposed critical area boundary. Critical area designations (IDA, LDA, RCA, etc) were pulled from the current designation layer and fit to the new boundary. Extensive discussions with County officials and Critical Area Commission resulted in a complete review of designations.</SPAN></P><P><SPAN /></P><P><SPAN /></P></DIV></DIV></DIV>
The remapping of Maryland's Critical Area has been a collaboration of the Critical Area Commission, Maryland Department of Natural Resources, Maryland Department of Information Technology, Somerset County, and ESRGC at Salisbury University.

Digitize shoreline and tidal wetlands from orthoimagery and orthophotography
Buffer tidal shoreline and landward edge of tidal wetlands by 1000-foot.
Jurisdiction provided their current critical area boundary containing designation information. This polygon layer was converted to lines and the interior boundaries were selected and exported to a new file.
Merge new shoreline, proposed critical area boundary and current interior designation boundaries. Run topology on merged line features.
Build polygons using point features derived from current CBCA polygon layer.
