A water-oriented accessory structure is a small building or other improvement, except stairways, fences, docks, and retaining walls, that, because of the relationship of its use to public waters, needs to be located closer to public waters than the normal structure setback. Examples include gazebos, screen houses, fish houses, pump houses, and detached decks and patios.
The regulations on water-oriented accessory structures are the following:
One water-oriented accessory structure is allowed for each riparian lot or parcel less than 300 feet in width at the ordinary high water level, with one additional water-oriented accessory structure allowed for each additional 300 feet of shoreline on the same lot or parcel. Water-oriented accessory structures must:
1. Not exceed 12 feet in height;
2. Not exceed 120 square feet in area;
3. Be placed a minimum of ten feet from the ordinary high water level; and
4. Not be placed within the bluff impact zone.
