(A) Buildings which have been elevated and have fully enclosed areas below the flood protection elevation (other than basements), as well as garages and accessory structures which are not elevated (§ 151.090), shall be constructed with water equalizing vents which meet or exceed the following standards:
(1) A minimum of 2 openings on different walls having a total net area of not less than 1 square inch for every square foot of enclosed area subject to flooding;
(2) The bottom of all openings shall be no higher than 1 foot above grade; and
(3) Openings may be equipped with screens, louvers, valves, or other coverings or devices, provided that they permit the automatic entry and exit of floodwaters to equalize hydrostatic forces on the walls.
(B) Fully enclosed areas below the flood protection elevation shall be used solely for parking of vehicles, access to the building, or storage. If such areas are enclosed, a declaration of land restriction recorded among the land records of Garrett County shall be required, in addition to an agreement to install water equalizing vents as specified in § 151.086.
