Wetland Mitigation: An In-depth Look for Airports

Many airports have been built near wetlands; their original construction and subsequent expansion have resulted in the loss of wetlands. The Clean Water Act regulates impacts to wetland resources, and Executive Order 11990 requires federal agencies to avoid and minimize wetland impacts where possible. In 1989, the United States government established a "no net loss" policy with the goal of compensating for the loss of wetland resources through mitigation. Currently, there are many accepted forms of wetland mitigation, and requirements often vary by region. Successful mitigation strategies are required for permit compliance and also for the continuing safety of airport operations, yet wetland mitigation can be challenging due to concerns over the creation of wildlife hazards and maintenance of obstruction free zones. More detailed information on the types of wetland mitigation available would be helpful for both airports and regulatory agencies in determining the most appropriate form of mitigation. The objectives of this research are to: (1) describe current practice, including how wetland mitigation policy, permitting, and design criteria vary among regions; (2) identify considerations associated with designing and implementing wetland mitigation sites in proximity to airports; and (3) provide case studies of actual airport-associated wetland mitigation projects that detail their planning, permitting, design, implementation, maintenance, and cost.
