(a) Maps. The waterway maps prepared by the Office of Planning and Zoning and adopted in 1979 are adopted as part of this article for the purpose of determining marina basins.
(b) Limits of marina basin. The limits of the marina basin are the mean high-water line of the site before development or expansion, two side marina lot line extensions, and a line drawn to connect their channelward ends.
(c) Side lot line extensions. The length of each side marina lot line extension shall be limited to the lesser of:
(1) one-half the distance from the mean high-water line to the center point of a cove;
(2) 100 feet less than the distance from the mean high-water line to the edge of the delineated channel and anchorage, except that the channelward extension of the side marina lot line or the line connecting the channelward ends may not be less than one-half the distance from the mean high-water line to the edge of the delineated channel and anchorage; or
(3) 500 feet from the mean high-water line.
(d) Direction of side lot line extensions. The Office of Planning and Zoning shall designate the direction of a marina basin side lot line extension along a line:
(1) at a 90-degree angle to the mean high-water line of the property at the intersection of the side marina lot line with the mean high-water line;
(2) at a 90-degree angle to the center line of the body of water;
(3) extending the side marina lot line past its intersection with the mean high-water line;
(4) connecting the point of intersection between the side marina lot line and the mean high- water line with the center point of a cove; or
(5) generally parallel to existing piers on adjacent properties.
