The Planning Board administers review under Article 7, and appeal from a Planning Board denial runs to the Board of County Commissioners.

The County Attorney or an official designated by the Board of Commissioners can also sue to enjoin an illegal subdivision, transfer, or sale, and a metes-and-bounds description in a deed does not exempt the transaction from prosecution.
