Chapter ATCP 48

ATCP 48.08(4) (4) Land use categories. When estimating land values under sub. (1) (a), a county drainage board may consider any of the following land use categories or other categories which the county drainage board considers appropriate:

ATCP 48.08(4)(a) (a) Residential uses.

ATCP 48.08(4)(b) (b) Commercial uses.

ATCP 48.08(4)(c) (c) Cropland, including dryland cropland, pasture, irrigated cropland or cranberry cropland.

ATCP 48.08(4)(d) (d) Abandoned cropland, including former agricultural land not currently used for agricultural, residential or commercial purposes.

ATCP 48.08(4)(e) (e) Woodland, including managed and unmanaged woodlands.

ATCP 48.08(4)(f) (f) Wetlands, including soils with standing water that have no significant agricultural value.

ATCP 48.08(5) (5) Drainage assumptions. When estimating land values associated with a potential use, a county drainage board may assume that the drained lands have access to an outlet at the formally established grade profile and cross-section, and that the necessary on-site drainage facilities are installed to permit the potential use.

ATCP 48.10 ATCP 48.10 Assessing benefits to nonagricultural lands.

ATCP 48.10(1) (1) Factors considered. When assessing benefits to nonagricultural lands in a drainage district, a county drainage board may consider all the factors specified for agricultural lands under s. ATCP 48.08 (1). The county drainage board may also consider the extent and frequency of additional discharges from the nonagricultural lands to district drains, and the drainage district’s cost to accommodate those additional discharges. Additional discharges may include additional discharges of stormwater, wastewater, or precipitation runoff from impermeable surfaces.

ATCP 48.10 Note Note: The county drainage board may also assess upstream municipalities for costs of enlarging or maintaining drains that are attributable to increased water flow from the municipality. See s. 88.64, Stats., and s. ATCP 48.04 (3).

ATCP 48.10(2) (2) Allocating assessments. A county drainage board may assess benefits to nonagricultural lands, including rural subdivisions or individual rural residences, based on a flat amount per lot, per acre, or per building or residence.

ATCP 48.10 Note Note: See s. 88.35, Stats.

subch. IV of ch. ATCP 48 Subchapter IV — District Map, Drains and Corridors

ATCP 48.20 ATCP 48.20 Drainage district specifications.

ATCP 48.20(1) (1) Specifications required. By December 31, 2000, every county drainage board shall adopt complete specifications for each drainage district under that board’s jurisdiction. The department shall approve the specifications before the county drainage board adopts them. The specifications shall include all of the following:

ATCP 48.20(1)(a) (a) A map which clearly and accurately shows all of the following:

ATCP 48.20(1)(a)1. 1. The boundaries of the drainage district, as last confirmed by the circuit court or as last revised by the county drainage board under ss. 88.77 to 88.80, Stats.

ATCP 48.20 Note Note: If the existing boundary of a drainage district is not clearly documented by a circuit court order, or by a county drainage board order under ss. 88.77 to 88.80, Stats., the county drainage board should clarify that boundary by appropriate procedures under ss. 88.77 to 88.80, Stats. See s. ATCP 48.21 (1).

ATCP 48.20(1)(a)2. 2. The intended alignment and extent of every district drain. If private drains are connected to district drains, the map shall clearly identify which drains, or portions of drains, are district drains.

ATCP 48.20(1)(a)3. 3. The intended location and width of every district corridor required under s. ATCP 48.24.

ATCP 48.20(1)(b) (b) The intended cross-section of every district drain. Each vertical section in the cross-section of a district ditch shall include all of the following elements:

ATCP 48.20(1)(b)1. 1. The intended top and bottom width of the ditch.

ATCP 48.20(1)(b)2. 2. The intended depth of the ditch.

ATCP 48.20(1)(b)3. 3. The intended side slope angle of the ditch.

ATCP 48.20(1)(b)4. 4. Any drainage structures intersected by that vertical section.

ATCP 48.20 Note Note: The vertical sections comprising the cross-section of a district drain should normally be taken at intervals of not more than 1/3 mile along the entire length of the drain, and at points where structures or changes in drain slope occur.

ATCP 48.20(1)(c) (c) The grade profile of every district drain. The grade profile of a district ditch shall include all of the following elements:

ATCP 48.20(1)(c)1. 1. The intended grade elevations of the top and bottom of the ditch.

ATCP 48.20(1)(c)2. 2. The estimated water surface elevations in the ditch at base flow. The county drainage board shall use a method described in ch. ATCP 48 Appendix A, or another method approved by the department, to estimate water surface elevations at base flow.

ATCP 48.20(1)(c)3. 3. The peak water surface elevations in the ditch in the event of a 10-year 24-hour storm event. The county drainage board shall use the method described in ch. ATCP 48 Appendix A, or another method approved by the department, to estimate peak water surface elevations in the event of a 10-year 24 hour storm event.

ATCP 48.20 Note Note: The formally established “grade profile” effectively determines drainage access and the depth of drainage provided to landowners. When a county drainage board documents the “grade profile” of a district drain, the county drainage board may also wish to determine the elevations of known points at which private drains empty into that district drain.

ATCP 48.20(2) (2) Notice to landowners; opportunity to object. Before a county drainage board applies to the department for approval of proposed drainage district specifications required under sub. (1), the county drainage board shall do all of the following:

ATCP 48.20(2)(a) (a) Mail or deliver, to every known landowner in the drainage district, written notice of the proposed specifications. The notice shall include the proposed specifications or shall explain how the landowner may obtain them. The notice shall also include an announcement of the meeting required under par. (c), including the date, time and place of the meeting.

ATCP 48.20(2)(b) (b) Publish a class 2 notice, under ch. 985, Stats., of the meeting under par. (c). The notice shall explain the purpose of the meeting, and shall include the meeting date, time and place.

ATCP 48.20(2)(c) (c) Hold a public meeting to explain and discuss the proposed specifications. The county drainage board shall make the proposed specifications available for public inspection at the meeting.

ATCP 48.20(2)(d) (d) Give landowners at least 30 days after the public meeting to file, with the county drainage board, written objections to the proposed specifications.

ATCP 48.20(3) (3) Department approval.

ATCP 48.20(3)(a) (a) To obtain the department’s approval under sub. (1), a county drainage board shall file all of the following with the department:

ATCP 48.20(3)(a)1. 1. The drainage district specifications for which the county drainage board seeks approval.

ATCP 48.20(3)(a)2. 2. A description of how the county drainage board established the specifications.

ATCP 48.20(3)(a)3. 3. Documentation showing that the county drainage board has complied with sub. (2).

ATCP 48.20(3)(a)4. 4. Notice of every landowner objection filed under sub. (2) (d).

ATCP 48.20(3)(a)5. 5. The county drainage board’s position on every unresolved objection under sub. (2) (d).

ATCP 48.20(3)(a)6. 6. Other relevant information required by the department.

ATCP 48.20(3)(b) (b) Within 90 days after a county drainage board files a complete application under par. (a), the department shall approve or disapprove the specifications proposed by the county drainage board. The department may, for good cause, extend the approval deadline to a date specified by the department.

ATCP 48.20 Note Note: The department will consult with the department of natural resources before approving drainage district specifications proposed by the county drainage board. Among other things, the department will ask the department of natural resources to identify which, if any, drains in the district have a navigable stream history.

ATCP 48.20(4) (4) Filing approved specifications. Within 30 days after the county drainage board adopts drainage district specifications under this section, the county drainage board shall file the specifications with the department, the county zoning administrator and the county register of deeds. Specifications are not formally established until they are approved, adopted and filed.

ATCP 48.20 Note Note: A landowner may challenge formally established drain specifications that violate this chapter or ch. 88, Stats., even if the department has approved those specifications. (In some cases, the department may not be aware of a violation when it approves the specifications.)
