This district preserves and enhances the streetscape along designated corridor highways in Gaston County. A (CH) district may exist along the entire length of a roadway or any identifiable segment of a roadway. Any (CH) District initially established shall contain a minimum length of at least 1,000 linear feet as measured along one side of a designated corridor highway. The (CH) district shall consist of all lots fronting on the corridor highway for a depth of 250 feet as measured from the centerline of the corridor highway for a total width of 500 feet, unless otherwise indicated on the Zoning Map. Although such corridor highways may vary in character, particular aspects of development along those roads raise common concerns and should be managed in a consistent way in order to preserve and enhance the streetscape.
