Marine Definitions

Access walkway means the portion of a structure that allows access to a docking facility or terminal platform.

Boathouse means a roofed structure constructed over or adjacent to water to provide a covered mooring or storage place for watercraft.

Boat canopy means a removable protective cover installed to cover a boat located in the principal mooring area of a dock or over a boat lift; a boat canopy is designed and intended for the purpose of protecting a marine vessel from damage from the elements and is fastened to, erected on, or installed on a marine improvement. For purposes of this Section, covers that protect marine vessels from the elements, but that fasten only to the marine vessel and not, in any way, to a marine improvement shall not be deemed to be "boat canopies".

Boatramp means an inclined and stabilized surface that extends into the water from the shore and upon which trailered watercraft can be launched and retrieved.

Docking facility means a water-oriented structure designed primarily for the launching, retrieval, storage or mooring of watercraft.

Exterior property line means the side lot line or riparian property line separating two or more lots or parcels under common ownership from the adjoining lots or parcels under separate ownership.

Finger pier means a dock landing that branches from an access walkway or terminal platform to form a watercraft slip and provide direct access to watercraft moored in the slip.

Hazard to navigation means a watercraft or structure erected, under construction or moored that obstructs the navigation of watercraft proceeding along a navigable channel or obstructs reasonable riparian access to adjacent properties.

Littoral zone means the shallow-water region of a waterbody where sunlight penetrates to the bottom.

Mangrove means any specimen of the species black mangrove (Avicennia germinans), white mangrove (Laguncularia racemosa), or red mangrove (Rhizophora mangle).
Marginal dock means a dock that runs parallel and adjacent to the shoreline. This term includes docks with a maximum access walkway length of 25 feet to a dock running parallel to the shoreline and adjacent to wetland vegetation.

Marine Improvement means a whole, constructed marine structure including, but not limited to, dock, boat lift, mooring posts, walkways, and other interconnecting parts. A boat canopy, its supports, and its frame shall not be considered to be a part of the marine improvement to which they are attached.

Mean high water means the average height of the high waters over a 19-year period. For shorter periods of observation, "mean high water" means the average height of the high waters after corrections are applied to eliminate known variations and to reduce the result to the equivalent of a mean 19-year value.

Mean high-water line means the intersection of the tidal plane of mean high water with the shore.

Mean low water means the average height of the low waters over a 19-year period. For shorter periods of observation, "mean low water" means the average height of the low waters after corrections are applied to eliminate known variations and to reduce the result to the equivalent of a mean 19-year value.

Mean low-water line means the intersection of the tidal plane of mean low water with the shore.

Mooring area means the portion of a docking facility used for the mooring of watercraft.

Mooring Post means a post or piling inserted into the bed of the waterway, either freestanding or part of a dock, and of sufficient strength to secure a vessel when made fast thereto.

Navigable channel means the area within a natural or artificial waterbody that will allow passage of a watercraft drawing three feet of water at mean low water.

Private single-family docking facility means a docking facility designed and intended to serve as an accessory use to an existing or proposed single-family dwelling unit.

Retaining wall means a vertical bulkhead constructed landward of the mean high water line and wetland vegetation.

Structure refers to any water-oriented facility and includes, without limitation, any dock, boardwalk, floating dock, fishing pier, pier, wharf, observation deck, deck, platform, boathouse, mooring piling, riprap, revetment, seawall, bulkhead, retaining wall, jetty, platform, boat lift, davit or boatramp, or any other obstacle, obstruction or protrusion used primarily for the landing, launching or storage of watercraft, erosion control and shoreline stabilization, or for water-oriented activities.

Terminal platform means the part of a docking facility connected to and generally wider than the access walkway that is used both for securing and loading a vessel.

Waterbody means all artificial and natural bodies of water.

Watercraft means any vehicle designed for transporting persons or property on, in or through water.

Watercraft slip means the area of a structure designated for watercraft mooring.

Waterfrontage line means the line at which a waterfront parcel abuts the waterway. If the waterfront parcel has a seawall, the seawall face shall be deemed the waterfrontage line for the parcel. For waterfront parcels that have a property line, but no seawall, abutting the waterway, such property line shall be deemed the waterfrontage line.
