NR 129.03(2) (2) “Authorized representative” means the municipal official or employee designated by resolution of the governing body of a municipality to act on behalf of the municipality in obtaining a grant under this chapter.

NR 129.03(3) (3) “Detailed floodplain study” means a hydrologic and hydraulic analysis to determine the flood flow discharge for a given flood frequency and the resulting water surface profile of a watercourse.

NR 129.03(4) (4) “Department” means the department of natural resources.

NR 129.03(5) (5) “Flood” means a general and temporary condition of partial or complete inundation of normally dry land areas caused by the overflow or rise of rivers, streams, or lakes.

NR 129.03(7) (7) “Flood fringe” means that portion of the floodplain outside of the floodway, which is covered by flood waters during the regional flood, and is generally associated with standing water rather than rapidly flowing water.

NR 129.03(8) (8) “Floodplain management” means the full range of public policy and action for insuring wise use of floodplains. It includes everything from the collection and dissemination of flood control information to actual acquisition of floodplain lands and the enactment and administration of codes, ordinances and statutes for land use in the floodplain.

NR 129.03(9) (9) “Floodway” means the channel of a river or stream and those portions of the floodplain adjoining the channel required to carry and discharge the flood water or flood flows associated with the regional flood.

NR 129.03(10) (10) “High flood damage potential” means the potential for any danger to life or health and any significant economic loss to a structure or building or its contents.

NR 129.03(11) (11) “Municipality” means any county, city or village.

NR 129.03(12) (12) “Official floodplain zoning map” means the map or maps adopted by a county, city or village, approved by the department, referenced in an official floodplain zoning ordinance and used for regulatory purposes.

NR 129.03(13) (13) “Official shoreland zoning map” means the map or maps adopted by a county, approved by the department, referenced in the county’s official shoreland zoning ordinance and used for regulatory purposes.

NR 129.03(14) (14) “Regional flood” means the flood determined to be representative of large floods known to have generally occurred in Wisconsin and which may be expected to occur on a particular stream because of like physical characteristics. The regional flood is based upon a statistical analysis of streamflow records available for the watershed and/or an analysis of rainfall and runoff characteristics in the general watershed region. The flood frequency of the regional flood is once in every 100 years; this means that in any given year there is a 1% chance that the regional flood may occur. During a typical 30-year mortgage period, the regional flood has a 26% chance of occurring.

NR 129.03(15) (15) “Shoreland” means lands within the following distances from the ordinary high-water mark of navigable waters: 1000 feet from a lake, pond, or flowage; and 300 feet from a river or stream or to the landward side of the floodplain, whichever distance is greater.

NR 129.03(16) (16) “Structure” means any public or private man-made object with form, shape and utility, either permanently or temporarily attached to or placed upon the ground, river bed, stream bed or lakebed.

NR 129.06(2)(a)5. 5. Costs attributable to the correction of errors or deficiencies in the mapping due to the consultant’s failure to comply with contract specifications; and

NR 129.06(2)(a)6. 6. The cost of a detailed floodplain study.

NR 129.06(2)(b) (b) Where 2 foot, or less, contour interval mapping is available, the department may, in its discretion, declare that project area ineligible. In exercising this discretion, the department shall consider changes in land development conditions which may render existing mapping obsolete.

NR 129.06(3) (3) Allocation of costs. Total project costs may be allocated between eligible and ineligible project areas using one of the following methods:

NR 129.06(3)(a) (a) Unit cost method. When this method is used, individual work items are prorated between eligible and ineligible project areas based on an equal cost per unit area.

NR 129.06 Note Note: The following is an example of the calculation of an individual work item using the unit cost method: If the cost of aerial photography is $500.00 per square mile (640 acres), and there are 320 acres of eligible project area, the eligible project cost would be $500.00 × (320/640) = $250.00.

NR 129.06(3)(b) (b) Project cost method. When this method is used, eligible project costs are based on the total estimated cost of mapping only the eligible project area. Field work or data collection (e.g., ground control survey or aerial photography) outside the eligible project area may be eligible if it is necessary for the completion of the project. Projects using this method are required to submit the consultant’s fee schedule showing the breakdown of eligible work items.

NR 129.06(3)(c) (c) Original cost estimates based on either method may be increased, using the grant amendment procedure in s. NR 129.07 (2), if it is determined upon completion of the final maps that the actual eligible project area is significantly larger than the area originally estimated to be eligible.
