Ala. Code § 18-1A-171

The amount of compensation to which the owners and other parties interested therein are entitled must not be reduced or diminished because of any incidental benefits which may accrue to them or to their remaining lands in consequence of the uses to which the lands to be taken or in which the easement is to be acquired will be appropriated; provided, that in the condemnation of lands for ways and rights-of-way for public highways, water or sewer lines, the commissioners or jury may, in fixing the amount of compensation to be awarded the owner for lands taken for this use, take into consideration the value of the enhancement to the remaining lands of such owner that such highway, water or sewer lines may cause; and provided further, that in proceedings instituted by water conservancy districts and water management districts, benefits accruing to the landowner from an improvement may be considered and allowed as a setoff against the damages to be awarded, but benefits derived from improvements other than the improvement for which the land is condemned cannot be considered; and provided further, that in the condemnation of lands, rights, easements, or interests in land, lying seaward of the construction control line then in effect under the regulations of the Alabama Department of Environmental Management, the ordinances of a coastal municipality, or both, for use by a coastal municipality in the establishment and maintenance of a beach project permitted pursuant to Section 9-15-56, the commissioners or jury, in fixing the amount of compensation to be awarded the owner for the lands, rights, easements, or interests lying seaward of the construction control line taken for such use, shall take into consideration the value of the enhancement to the remaining lands of the owner that the beach project may cause as the result of the placement of sand directly on and directly seaward of the lands, or rights, easements, or interests in land so taken. To the extent, and only to the extent, that sand is placed directly on and directly seaward of the lands, or rights, easements, or interests in land so taken, the commissioners or jury may presume:

(1) That the value of the remaining lands of the owner will exceed the value of all lands, rights, easements, and interests of the owner prior to the taking as a result of the enhancement in value resulting from the beach project.

(2) That the owner has sustained no damage and is entitled to no compensation as a result of the taking.

The presumptions shall be rebutted only by substantial evidence adduced by the owner.
