Coastline of bays and sounds is included to point where they narrow to width of unit measure, and distance across at such point is included.

Tidal shoreline figures were obtained in 1939-1940 with recording instrument on largest-scale maps and charts then available. Shoreline of outer coast, offshore islands, sounds, bays, rivers, and creeks is included to head of tidewater, or to point where tidal waters narrow to width of 100 feet.
