La. Stat. tit. 38 § 1623
Within twenty days after having been petitioned for the carrying out of the plan for reclamation of the drainage district or of any sub-district, the board of commissioners shall name and appoint three appraisers who shall be residents of Louisiana, over the age of twenty-one years, who shall not be landowners in the drainage districts, nor related within the fourth degree of consanguinity to any person owning land in the district, nor be an officer or stockholder or bondholder of any corporation owning land in the district. These facts affecting the qualification of appraisers shall be made affirmatively to appear in the oath of each appraiser, and the oath shall make prima facie proof that the appraiser was legally qualified to act as an appraiser.
The three appraisers shall be known as "Board of Appraisers". They shall appraise the land within and without the drainage district or sub-district to be acquired for rights of way, holding basins, levees, canals, pumping plant sites, and other drainage works of the district, and to assess benefits and damages accruing to all land in the district or sub-district and other property by reason of the execution of the plan for reclamation.
