Section 30-10 - Critical Area Boundaries

(1) The Department has permit authority over the coastal waters and tidelands critical areas defined in Section 48-39-10 as follows:

(2) Using biological field surveys and aerial photography, the Department has found the point on the upper reaches of the estuarine systems where tideland vegetation changes from predominately brackish to predominately fresh and has established a boundary using the nearest recognizable physical features within this area. This boundary has been posted on an official map in SCDHEC-OCRM'S principal offices of business and is available for public review. An approximate description of this boundary is as follows: On the south at the intersection of the South Carolina-Georgia border and the old track bed of the Seaboard Coastline (SCL), approximately 1.75 miles above the U.S. Highway 17-A bridge across the Savannah River; thence, northeastward along the track bed until its intersection with S. C. 462 near Euhaw Creek; thence, northward along S. C. 462 until its intersection with U.S. Highway 17/U.S. Interstate 95 near Coosawhatchie; thence, northeastward along U.S. 17/U.S. Interstate 95 until U.S. Highway 17 and U.S. Interstate 95 intersect at Point South, thence, northeastward along U.S. 17 until its intersection with S-15-26, approximately two miles east of Green Pond; thence, southward along S-15-26 (Bennetts Point Road) until its intersection with the old SCL track bed near Airy Hall; thence, east-northeastward along the track bed on its intersection with S. C. 174; thence, northward along S. C. 174 for approximately 1.5 miles until its intersection with S. C. 164; thence, east-northeastward approximately three miles along S. C. 164 until its intersection with S. C. 165; thence, northward along S. C. 165 (Bacons Bridge Road) until its intersection with S. C. 642 (Dorchester Road); thence, southeastward along S. C. 642 until its intersection with U.S. Interstate 26; thence, southward along I-26 until its intersection with S. C. 7 (Cosgrove Avenue); thence, northeastward on S. C. 7 until its intersection with the SCL track bed adjacent to S-10-32 (Spruill Avenue); thence, northward along this track bed until its intersection with the Charleston County/Berkeley County line, approximately one-fifth mile north of S-10-13 (Remount Road); thence, east-northeastward along the county line until its intersection with the Cooper River at Goose Creek; thence, eastward by a straight line across the Cooper River and mouth of Yellow House Creek to Jessen Road at the Cainhoy Industrial Park, thence southeastward until its intersection with (Clements Ferry Road); thence, northeastward along S-8-33 until its intersection with S-8-100 (Resurrection Road) until its intersection with S. C. 41, thence northeastward on S-8-100 (Halfway Creek Road); thence, northeastward along S-8-100 until its intersection with S-10-98 (Guerins Creek Bridge Road); thence, southward along S-10-98 until its intersection with U.S. Highway 17; thence, northeastward along U.S. Highway 17 until its intersection with S-27-30 north of the North Santee River; thence, eastward along S-27-30 for approximately five miles; thence, northward along S-27-30 until its intersection with S-27-18; thence, northwestward along S-27-18 until its intersection with U.S. Highway 17 south of Georgetown, thence northeastward along U.S. Highway 17 (Frasier Street) through Georgetown, thence northeastward along U. S. Highway 17 until the intersection of U.S. Highway 17 Business and U.S. Highway 17 Bypass south of Murrells Inlet; thence, northeastward along U.S. Highway 17 Business (Kings Highway) through Murrells Inlet, Garden City, Surfside Beach, and Myrtle Beach until its intersection U.S. Highway 17 north of Myrtle Beach; thence northeastward along U.S. Highway 17 until its intersection with the South Carolina-North Carolina border. In determining the exact location of this boundary, only those lands seaward of the right-of-way line located on the upstream side of road beds and track beds described shall be included in the tidelands and coastal waters critical areas.

(3) All coastal waters and tidelands seaward from this boundary to the State jurisdictional limit are included within the critical areas.
