ATCP 50.74 ATCP 50.74 Hydrologic restoration.

ATCP 50.74(1) (1) Definition. In this section “Hydrologic restoration” means applying combinations of practices designed to the extent possible to return wetland, stream, and floodplain hydrology to a natural and self-regulating condition in order to achieve such agricultural goals as to slow the flow of runoff, reduce flood peaks, restore surface and groundwater interactions, improve water quality, or increase soil retention, groundwater infiltration, base flow, upper watershed storage, and flood resilience. These practices can also be used to reduce or repair erosion and maintain water supply. These benefits are achieved by improving hydrologic conditions, connections, and functions. Hydrologic restoration practices may improve and protect fish and wildlife habitat as an incidental benefit. Hydrologic restoration may include any of the following components:

ATCP 50.74(1)(a) (a) Diversions under s. ATCP 50.70.

ATCP 50.74(1)(b) (b) Grade stabilization structures under s. ATCP 50.73.

ATCP 50.74(1)(c) (c) Streambank or shoreline protection under s. ATCP 50.88.

ATCP 50.74(1)(d) (d) Stream restoration under s. ATCP 50.882.

ATCP 50.74(1)(e) (e) Stream crossing under s. ATCP 50.885.

ATCP 50.74(1)(f) (f) Subsurface drains under s. ATCP 50.90.

ATCP 50.74(1)(g) (g) Underground outlets under s. ATCP 50.92.

ATCP 50.74(1)(h) (h) Water and sediment control basins under s. ATCP 50.95.

ATCP 50.74(1)(i) (i) Waterway systems under s. ATCP 50.96.

ATCP 50.74(1)(j) (j) Wetland development or restoration under s. ATCP 50.98.

ATCP 50.74(2) (2) Eligible costs. A cost-share grant under s. ATCP 50.40 may reimburse any of the following costs related to hydrologic restoration:

ATCP 50.74(2)(a) (a) Costs for system components under subs. (1) and (4) that are eligible for reimbursement under this subchapter.

ATCP 50.74(2)(b) (b) Costs to establish permanent vegetative cover, or to provide temporary cover pending the establishment of permanent cover. This may include costs for mulch, fertilizer, seed, and other necessary materials.

ATCP 50.74(2)(c) (c) Costs to purchase and install permanent fencing around the project area.

ATCP 50.74(2)(d) (d) Preparatory shaping and smoothing operations.

ATCP 50.74(2)(e) (e) Costs for site preparation, grading, shaping and filling.

ATCP 50.74(3) (3) Ineligible costs. Except for violations of this chapter or ch. NR 151, a cost-share grant under s. ATCP 50.40 may not reimburse costs related to mitigation or correction of a violation of state or local law.

ATCP 50.74(4) (4) Design, construction, and maintenance standards. A cost-share grant under s. ATCP 50.40 may not reimburse hydrologic restoration costs unless all of the following conditions are met:

ATCP 50.74(4)(a) (a) The hydrologic restoration complies with all of the following that apply:

ATCP 50.74(4)(a)1. 1. NRCS conservation practice standard 315 herbaceous weed treatment (June, 2016).

ATCP 50.74(4)(a)2. 2. NRCS conservation practice standard 327 conservation cover (January, 2013).

ATCP 50.74(4)(a)3. 3. NRCS conservation practice standard 332 contour buffer strips (July, 2016).
