NR 328.01(6) (6)Standards for general permits are intended to ensure that cumulative adverse environmental impact of authorized activities is insignificant and that issuance of the general permit will not injure public rights or interests, cause environmental pollution as defined in s. 299.01 (4), Stats., or result in material injury to the rights of any riparian owner. To achieve this, general permit standards establish: construction and design requirements consistent with the purpose of the activity; location requirements that ensure that the activity will not have an adverse impact on fish and wildlife habitat, water quality and natural scenic beauty, or materially interfere with navigation or have an adverse impact on the riparian property rights of adjacent riparian owners.
NR 328.01(7) (7)Standards and factors for individual permits are intended to provide direction for detailed evaluation of permit applications, and to balance case-by-case review with consistent decision-making. Individual permits may only be granted where the department determines that the structure will not materially obstruct navigation, will not be detrimental to the public interest, and will not materially reduce the flood flow capacity of a stream.

NR 328.03 Note Note: 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.

NR 328.03(16) (16)“Offshore" means located a minimum of 10 horizontal feet waterward from the ordinary high water mark.
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 Note Note: 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(19) (19)“Permanent breakwater" means a structure constructed of stone, rock, concrete or other non-degradable materials and located offshore for the purpose of diminishing the force of the waves and protecting the shoreline.
NR 328.03 Note Note: 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 Note Note: 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 Note Note: 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.

(under development). All other projects affecting wetlands will require individual water quality certification including public notice as required by s. 401, Federal Clean Water Act, and s. 281.36 (3b) (b), Stats. and carried out under chs. NR 103 and 299. For further instructions, see the department's website at http://dnr.wi.gov under the topic “Waterway and Wetland Permits."
