Ala. Code § 35-2-8

Whenever coordinates based on the Alabama coordinate system are used to describe any tract of land which in the same document is also described by reference to any subdivision, line, or corner of the United States public land surveys, the description by coordinates shall be construed as supplemental to the basic description of such subdivision, line, or corner contained in the official plats and field notes filed of record; and, in the event of any conflict, the description by reference to the subdivision, line, or corner of the United States public land surveys shall prevail over the description by coordinates.
