Sec. 12. (a) All public-use heliports shall be inspected at least once a year by the department and shall maintain compliance with all standards that were required by the department as a condition of receiving a certificate of site approval. (b) All public-use seaplane bases shall be inspected at least once a year by the department and shall maintain compliance with the following minimum requirements: (1) The body of water shall have a minimum usable area of at least two thousand six hundred seventy-five (2,675) feet by one hundred (100) feet with a two hundred (200) foot diameter turning basin at each end. The turning basin shall be included in the minimum length of two thousand six hundred seventy-five (2,675) feet and shall be of sufficient depth to permit the safe operation of aircraft on the surface. (2) All approaches to the landing area shall be sufficiently clear of obstruction to permit a 20:1 approach angle to the nearest point of the usable landing area, provided that if any structure on the land is located within three hundred (300) feet of the centerline of the approach path, the approach angle shall be computed so as to provide a clearance of at least one hundred (100) feet above the structure. (3) Any hazards, including underwater obstructions in the landing, approach, departure, and taxi areas, shall be marked with durable markers so as to be clearly visible from traffic pattern altitude.
