(a) Water wells and any appurtenant structures must be located a minimum distance of ten (10) feet from a levee toe.

(b) Oil wells, gas wells, and any appurtenant structures must be located a minimum distance of thirty-five (35) feet from a levee toe.

(c) Access roads, foundation pads, and stockpiled excavated material within a floodway are normally limited to an elevation of three (3) feet above the natural ground. However, if it is determined by the board that such facilities constructed to the normal elevation would have an adverse effect on the flood- carrying capacity of the floodway, the allowable elevation shall be lower.

(d) Structures and fencing at well sites within the floodway are not permitted without approved hydraulic studies demonstrating that the proposed structure or fence would not impair the floodway.

(e) Permits for water wells require that a survey monument and a permanent bench mark must be installed at the waterside levee toe, as near to the well site as practical, to serve as a vertical control to monitor subsidence.
