(a) Name. The name of the viticultural area described in this section is “Virginia's Eastern Shore.”

(b) Approved maps. The appropriate maps for determining the boundaries of the “Virginia's Eastern Shore” viticultural area are 3 U.S.G.S. Quadrangle (1:250,000 Series) maps. They are titled:

(1) Eastville, VA.; N.C.; MD., 1946 (revised 1969).

(2) Salisbury, MD.; DEL.; N.J.; VA., 1946 (revised 1969).

(3) Richmond VA.; MD., 1973.

(c) Boundary. The Virginia's Eastern Shore viticultural area is located in Accomack and Northampton counties, Virginia. The boundary is as follows:

(1) The beginning point is the intersection of the Virginia/Maryland border and Chincoteague Bay, near Greenbackville on the Salisbury, MD., U.S.G.S. map;

(2) From the beginning point, the boundary follows the coastline in a southwesterly direction. Where there are marshes indicated on the U.S.G.S. maps, the boundry is the inland side of these marshes;

(3) When the boundary reaches the southernmost point of the peninsula, on the Eastville, VA., U.S.G.S. map, the boundary turns and proceeds in a northwesterly direction, again following the coastline around Cherrystone Inlet on the Richmond, VA., U.S.G.S. map;

(4) The boundary continues to follow the coastline and the inland side of any marshes indicated on the U.S.G.S. maps in a northeasterly direction, until it reaches the Virginia/Maryland border on the Eastville, VA., U.S.G.S. map;

(5) The boundary then follows the Virginia/Maryland border back to the beginning point at Chincoteague Bay on the Salisbury, MD., U.S.G.S. map.
