It may be hard to envision today, but at the turn of the 18th century, almost 25% of Indiana’s land was covered by nearly 5.5 million acres of wetlands. However, the late 19th and early 20th centuries saw large drainage projects directed at converting the wetlands into agricultural land, dramatically decreasing the wetlands to a fraction of their original size. As Indiana was settled and its land drained and converted for other uses, its wetlands began to vanish; over 85% of the water world that existed around 1790 is gone today.
Overview of Indiana Wetlands
Wetlands are areas where the land is covered by water, either seasonally or year-round. Indiana's wetlands vary widely, from the Great Lakes marshes to the southern cypress swamps. These ecosystems are vital for maintaining biodiversity, controlling floods, and purifying water. Wetlands also provide various economic and societal benefits. Indiana wetlands are subject to specific regulations and protections aimed at preserving their ecological value.
Wetlands are home to diverse plant and animal species and provide numerous ecological and socio-economic benefits, including:
Biodiversity: Wetlands are incredibly diverse ecosystems that support a wide range of plant and animal species. They serve as critical habitats for various waterfowl, amphibians, reptiles, fish, and insects. Many of these species are rare, threatened, or endangered, making wetlands essential for conserving biodiversity in Indiana.
Water Quality: Wetlands act as natural filters, trapping sediments and pollutants from runoff and agricultural activities. This helps improve water quality in rivers, lakes, and streams by reducing the amount of contaminants that reach these water bodies.
Flood Control: Indiana is prone to heavy rainfall and flooding events. Wetlands play a crucial role in flood control by absorbing excess water during storms and releasing it slowly over time. This reduces the risk of downstream flooding and protects communities and infrastructure.
Recreation: Many wetlands in Indiana are used for recreational activities such as birdwatching, hiking, fishing, and hunting. They offer opportunities for outdoor enthusiasts to connect with nature and enjoy the state's natural beauty.
Economic Benefits: Wetlands contribute to the economy by supporting commercial and recreational fishing, hunting, and tourism. They also enhance property values and provide aesthetic and recreational value to local communities.
Carbon Sequestration: Wetlands are effective carbon sinks, storing significant amounts of carbon dioxide. Conserving and restoring wetlands can help mitigate climate change by reducing greenhouse gas emissions.
Education and Research: Wetlands provide valuable opportunities for scientific research and environmental education. They serve as living laboratories for studying ecological processes, climate change impacts, and habitat restoration techniques.
Agriculture: While wetlands can sometimes be seen as obstacles to agriculture, they also benefit the farming community. Wetlands can store excess water during heavy rains, preventing field flooding and soil erosion. They can also provide habitat for beneficial insects that help with pest control.
Resilience to Climate Change: Wetlands help buffer the impacts of climate change by reducing the severity of droughts, heat waves, and flooding events. They are crucial in building resilience in the face of changing climatic conditions.
State vs. Federal Wetlands Protection
Wetland regulation in Indiana involves a complex interplay of federal and state laws. At the federal level, the Clean Water Act provides a broad framework for wetland conservation. Indiana's state-level regulations, particularly the Indiana Isolated Wetlands law, complement these federal protections by covering wetlands that may not fall under federal jurisdiction.
Federal Regulations: The U.S. Army Corps of Engineers and the Environmental Protection Agency (EPA) enforce federal regulations under the Clean Water Act. Activities that may impact wetlands, such as construction or dredging, may require a permit from these agencies.
State Regulations: The Indiana Department of Environmental Management (IDEM) is responsible for implementing wetland regulations at the state level. IDEM enforces the State Isolated Wetlands law and the Lake Michigan Shoreline Development Act. These laws govern wetland protection and permitting in Indiana.
Wetland Considerations for Developers
The rationale for protecting wetlands extends beyond environmental reasons. Wetlands contribute significantly to the economy through activities like tourism and fishing. They also offer cost-effective natural flood protection and water filtration, reducing the need for expensive infrastructure. For developers, understanding these benefits can inform more sustainable project planning and community relations.
Key Takeaways for Developers and Companies:
Familiarity with both state and federal regulations is essential.
Protecting wetlands can enhance project value and community goodwill.
Early consultation with regulatory bodies can streamline project planning.

Navigating the Permitting Process
What is the Isolated Wetland Individual Permit (IWIP)?
The IWIP is an Indiana state-specific regulatory requirement essential for any project that may impact wetlands not covered by federal jurisdiction. This permit is critical in ensuring that developments comply with state laws regarding wetland conservation.
The Indiana Department of Environmental Management (IDEM) mandates the Isolated Wetland Individual Permit for any impact to a Class III wetland, irrespective of the wetland's acreage or the proposed impact. Class III wetlands, characterized by their unique ecological significance, require careful consideration and regulatory oversight.
Who Needs this Permit?
The IWIP is generally required for:
Developers planning projects in areas with isolated wetlands.
Companies involved in construction or land alteration near these wetlands.
Entities engaging in activities that could potentially disturb or change wetland ecosystems.
Step-By-Step Guide to Obtaining the Permit
Preliminary Assessment: Determine if your project site contains isolated wetlands.
Site Analysis: Conduct detailed wetland delineation and functional assessment.
Application Preparation: Compile necessary documentation, including impact assessments and mitigation plans.
Regulatory Review: Submit the application to the Indiana Department of Environmental Management (IDEM) for review.
Public Notice and Comment Period: Allow time for public input, as required by law.
Permit Decision: Await IDEM's decision, which may include conditions or modifications to the proposed project.
Key Considerations for a Smooth Permitting Process
Early identification of potential wetland areas is crucial.
Engage with experienced environmental consultants to accurately delineate wetlands and prepare necessary documentation.
Proactively address public concerns and feedback during the comment period.
Indiana Wetland Mitigation Requirements

Balancing Development and Wetland Conservation
Mitigation in the context of wetland management refers to the process of compensating for the impact caused by development activities. The goal is to ensure no net loss of wetland functions and values, which is a cornerstone of both federal and state wetland policies.
Benefits of Effective Mitigation
Effective wetland mitigation efforts can offer developers many benefits, including ensuring long-term environmental sustainability and enhancing the public image of the development project. Mitigation banking (one of the mitigation strategies described below) can also offer developers a cost-effective and time-efficient solution.
Mitigation Strategies
There are several approaches to wetland mitigation:
On-site Mitigation: Involves restoring, enhancing, or creating wetlands within the project area
Off-site Mitigation: Takes place outside the project site, often in areas identified as priorities for wetland restoration
Mitigation Banking: Developers can purchase credits from wetland mitigation banks, which represent wetland restoration or creation done by others
In-Lieu Fee Mitigation Program
For those unable to conduct on-site mitigation, Indiana offers an In-Lieu Fee Mitigation Program as an alternative. This program allows individuals or organizations to purchase credits at a cost ranging from $80,000 to $120,000 per acre, depending on the region. This approach provides flexibility for those facing constraints in implementing on-site mitigation measures.
Mitigation Ratios
Mitigation is a crucial aspect of wetland conservation, and the ratios and methodologies involved depend on various factors. According to IDEM's guidelines, the ratios for compensatory costs associated with purchasing mitigation credits are 1:1 if conducted beforehand, 2.5:1 for non-forested, and 3:1 for forested wetlands if conducted after the impact has occurred.
Understanding these ratios is essential for project planners and developers to ensure compliance with regulations while maintaining ecological balance. It is important to note that conducting mitigation before impacting the wetland results in a 1:1 ratio, providing a more straightforward approach to compliance.
Compliance with Mitigation Requirements
There are three critical steps developers should follow to comply with mitigation requirements successfully:
Conduct a thorough impact assessment.
Develop a mitigation plan that outlines how lost wetland functions will be replaced.
Seek approval for the mitigation plan from relevant regulatory agencies.
Implications of Recent Indiana Wetland Legislation
Before the latest Indiana wetland law went into effect in 2021, there was an assumption that wetland impacts of less than 0.1 acres did not require permitting. However, with the implementation of new regulations, this assumption may no longer hold true. The updated regulations, as outlined by IDEM, now mandate an IWIP for any impact to a Class III wetland, irrespective of size.
This change in legislation has significant implications for projects that previously fell below the 0.1-acre threshold. Developers and planners must now carefully assess the impact of their projects on isolated wetlands and ensure compliance with the updated regulations.
On January 25, 2024, Indiana House Bill 1383 - Wetlands, had its first reading in the State Senate and was referred to the Committee on Environmental Affairs for comment, progressing one step closer to being a ratified law. The proposed new Wetlands law will alter the regulatory landscape again should it be amended and adopted in the near future.
