NR 328.03 NoteNote: The maximum toe protection structure elevation is equal to the ordinary high water mark plus one-half of the storm-wave height.
NR 328.03 NoteNote: The toe protection relies on materials such as stone, armor units, fiber rolls or wattles to protect the base of the bank. Above the toe protection, the remainder of the bank is revegetated by installing a shoreland buffer or with brush layering, brush mattresses, fiber rolls, live stakes, vegetated geogrid, rolled erosion control products or wattles. Plant materials may also be incorporated as part of the shore protection design below the ordinary high water mark as well.

NR 328.03(17)(17) “Ordinary high water mark” means the point on the bank or shore up to which the presence and action of water is so continuous as to leave a distinct mark either by erosion, destruction of terrestrial vegetation or other easily recognizable characteristic. NR 328.03(18)(18) “Navigable waterway” means any body of water with a defined bed and bank, which is navigable under the laws of the state. In Wisconsin, a navigable body of water is capable of floating the lightest boat or skiff used for recreation or any other purpose on a regularly recurring basis. NR 328.03 NoteNote: This incorporates the definition at s. 30.01(4m), Stats., and current case law, which requires a watercourse to have a bed and banks, Hoyt v. City of Hudson, 27 Wis. 656 (1871), and requires a navigable waterway to float on a regularly recurring basis the lightest boat or skiff, DeGayner & Co., Inc. v.

NR 328.03 NoteNote: These structures can be designed to provide fish and wildlife habitat in addition to erosion control by incorporating vegetation on the breakwater and in the nearshore zone. Examples of permanent breakwaters include stone dikes, barrier islands, stone islands and submerged offshore shoals.
NR 328.03(20)(20) “Replacement” means a degree of structural changes to the shore erosion control structure by which some or all of the structure is being removed and recreated. NR 328.03 NoteNote: For seawalls, any replacement of a portion of the seawall down to or at the footing of the structure is considered replacement. For riprap, replacement of filter fabric or replacement of the base substrate is considered replacement.
NR 328.03(21)(21) “Riparian” means an owner of land abutting a navigable waterway. NR 328.03(22)(22) “Riprap” means a layer or layers of rock, including filter material, placed on the bed and bank of a navigable waterway to prevent erosion, scour or sloughing of the existing bank. NR 328.03(23)(23) “Seawall” means an upright structure that is steeper than 1.5 feet vertical to one foot horizontal and that is installed parallel to the shore to prevent the sliding or slumping of the land and to protect the adjacent upland from wave action.

NR 328.03 NoteNote: Temporary breakwaters are placed for the purpose of providing an area of quiescent water, when new erosion protection designs and shoreland plant installations are becoming established. Biological temporary breakwater designs degrade naturally and examples include branchbox breakwaters and fiber rolls.
NR 328.03(27)(27) “Toe” means the most waterward edge of a shore erosion control structure. NR 328.03(28)(28) “Vegetated armoring” means a shore erosion control structure that combines biological and inert materials, and includes 3 types: integrated toe protection, vegetated-riprap and vegetated-geogrids. NR 328.03(29)(29) “Wave height” means the vertical distance between the wave crest and wave trough. NR 328.03(30)(30) “Wetland” means an area where water is at, near or above the land surface long enough to be capable of supporting aquatic or hydrophytic vegetation and which has soils indicative of wet conditions.
