(20 ILCS 830/1-2) (from Ch. 96 1/2, par. 9701-2) Sec. 1-2. Legislative declaration. The General Assembly finds and determines that: (a) In 1818, Illinois contained an estimated 8.2 million acres of wetlands. Based upon preliminary results of the Illinois portion of the National Wetlands Inventory, less than nine percent of the original acres remain. (b) With the significant loss in acreage, a corresponding loss in the functional values and benefits that wetlands provide has occurred. (c) Continued loss of Illinois' wetlands may deprive the people of this State of some or all of the benefits which they provide, including: (1) reducing flood damages by absorbing, storing and conveying peak flows from storms; (2) improving water quality by serving as sedimentation and filtering basins and as natural biological treatment areas; (3) providing breeding, nesting, forage and protective habitat for approximately 40 percent of the State's threatened and endangered plants and animals, in addition to other forms of fish, wildlife, waterfowl and shorebirds; (4) protecting underground water resources and helping to recharge rivers, streams and local or regional underground water supplies; (5) serving as recreational areas for hunting, fishing, boating, hiking, bird watching, photography and other uses; (6) providing open space and aesthetic values, particularly in rapidly developing areas; (7) providing unique educational and research opportunities because of their high diversity of plants and animals, their support for a high incidence of threatened and endangered species, and their function as a natural buffer for rivers, lakes and streams; (8) supplying nutrients in freshwater food cycles and serving as nursery areas and sanctuaries for young fish; and (9) helping to protect shorelines from the forces of water erosion.

(b) "Adverse wetland impacts" means any land management and construction or related project activity which directly or indirectly reduces the size of a wetland or impairs a wetland's functional value, as described in subsection (c) of Section 1-2 of this Act, or the hydraulic and hydrologic characteristics of a wetland. (c) "Director" means the Director of Natural Resources. (d) "Department" with reference to this Act means the Department of Natural Resources. (e) "Committee" means the Interagency Wetlands Committee created by this Act. (f) "Mitigation" includes avoiding, minimizing or compensating for adverse wetland impacts. This includes: (1) Avoiding the impact altogether by not taking a certain action or parts of an action; (2) Minimizing the impact by limiting the magnitude of the action; and (3) Compensating for the impact by replacing or providing substitute wetland resources or environments. (g) "Agency Action Plan" means a plan developed by an individual agency to implement this Act. (h) "Wetland Compensation Plan" means a plan developed for each individual construction project that details how the responsible agency will compensate for actions which will result in adverse wetland impacts.

20 ILCS 830/3-1 State Wetland Mitigation Policy

(20 ILCS 830/3-1) (from Ch. 96 1/2, par. 9703-1) Sec. 3-1. State Wetland Mitigation Policy. This Act implements the State Wetland Mitigation Policy, which directs that each State agency shall preserve wetlands as a priority of action when they develop construction or land management plans. When an agency can establish that no other feasible alternative exists and adverse wetland impacts are unavoidable, adverse impacts are to be compensated for through the development and implementation of a Department approved Wetland Compensation Plan. The policy requires progressive levels of compensation based upon the level of impact to the existing wetland and the location of compensation wetlands. Priority shall be given to locating compensation wetlands close to the wetland area impacted. Proposed State and State-supported construction activities which may impact wetlands identified on the Illinois Natural Areas Inventory, under public ownership or which provide habitat for State or federally threatened or endangered species will continue to require direct consultation with the Department and compliance with the Endangered Species Protection Act of 1986.

20 ILCS 830/3-6

(20 ILCS 830/3-6) (from Ch. 96 1/2, par. 9703-6) Sec. 3-6. Compensation ratios. Wetland Compensation Plans must adhere to a schedule of increasing compensation ratios based upon the amount of adverse wetland impact and the location of compensation projects. (a) Compensation ratios are required to: (1) Ensure that wetland systems are not destroyed without careful evaluation of other alternatives; and (2) Discourage destruction of wetland resources in rapidly developing areas of Illinois and their replacement within other regions of the State. (b) Compensation ratios shall be established and shall be progressively higher to reflect the priority actions identified in Section 3-4. The lowest compensation ratio shall be for minimal alteration and compensation on-site. The highest compensation ratio shall be for destruction and compensation outside the impacted wetland's drainage basin. Progressively higher compensation ratios shall strongly encourage agencies to avoid or minimize adverse wetland impacts and to compensate on-site. (c) Compensation may be accomplished through a combination of creation of new wetlands, restoration of degraded wetlands, acquisition of existing wetlands, or research. Compensation shall be accomplished using the best available technology. (d) The Department, through the Interagency Wetlands Committee, shall review the compensation ratios to determine their adequacy and appropriateness, and shall report the results of this review in the biennial report required in Section 2-1. (e) When adverse wetland impacts occur, the Wetland Compensation Plan must include the creation of at least one-for-one replacement of new wetlands of comparable functional type and size, before restoration, acquisition or research alternatives are considered. One provision of a Wetland Compensation Plan may include funding for needed research on wetland functions, restoration or creation. Credit for research funding requires approval of the Department upon consultation of the Committee. (Source: P.A. 86-157.)
