(1) An artificial obstruction or nonconforming use in a designated flood plain or designated floodway enforced under 76-5-301(1) and (2) and not exempt under 76-5-401 through 76-5-403 or subsection (2) or (3) of this section is a public nuisance unless a permit has been obtained for the artificial obstruction or nonconforming use from the department or the responsible political subdivision.
     (2) It is unlawful for a person to establish an artificial obstruction or nonconforming use within a designated flood plain or a designated floodway without a permit from the department or the responsible political subdivision.
     (3) (a) Parts 1 through 4 of this chapter do not affect any existing artificial obstruction or nonconforming use established in the designated flood plain or designated floodway before the land use regulations adopted by the political subdivision are effective or before the department has enforced a designated flood plain or a designated floodway under 76-5-301(1) and (2).
     (b) However, a person may not make nor may an owner allow alterations of an artificial obstruction or nonconforming use within a designated flood plain or a designated floodway whether the obstruction proposed for alteration was located in the flood plain or floodway before or after July 1, 1971, except upon express written approval of the department or the responsible political subdivision. Maintenance of an obstruction is not an alteration.
