Indiana

Note: Most states have enacted laws and regulations to protect wetlands. In many cases, these rules are established to define the state's role in the "§404 permit/§401 certification process." This process involves the U.S. Army Corps of Engineers and your state environmental agency. To learn more about the wetlands permitting process go to the CICA Wetlands Regulations/Permit page.

Primary State Wetlands Web Page. This web page should explain the state wetlands program and provide links to various wetlands resources.

Construction Permit Process - State Rules

    How Are Wetlands Activities Regulated by Indiana? Any person who wishes to place fill materials, excavate or dredge, or mechanically clear (use heavy equipment) within a wetland, lake, river, or stream must first apply to the U.S. Army Corps of Engineers (USACE) for a Section 404 permit. If the Corps of Engineers determines that a wetlands (Section 404) permit is needed, then the applicant also must obtain a Section 401 Water Quality Certification from the IDEM Office of Water Quality (OWQ).

    Mitigation Measures. For projects that exceed 0.1 ac of wetland impacts (as a general rule), or for smaller impacts to high quality wetlands, mitigation is required. In most cases, mitigation involves restoring or creating wetlands similar to those impacted, at a ratio of at least 1.5:1.0 (mitigation:impact), in the vicinity of the impact. Very rarely is enhancement or protection of an existing wetland approved as mitigation, but technically they are options. For impacts to wetlands that are dominated by grasses, wildflowers and other herbaceous plants, the impact ratio is generally between 1.5:1 and 2:1. For wetlands dominated by shrubs and saplings the ratio usually varies from 2:1 to 3:1. Wetlands dominated by trees are replaced at a 3:1 to 4:1 ratio. These ratios can be increased by the regulatory agencies based on the quality of the wetland impacted and the distance of the mitigation site from the impacted site.
