An interagency group including the Corps, Environmental Protection Agency, U.S. Fish and Wildlife Service, and the Municipality of Anchorage formulated a mitigation agreement. The major portion of the mitigation agreement consists of permanent preservation and restoration of 243 acres of wetlands in an area of south Anchorage known as Klatt Bog. This area has been under severe developmental pressure for the past two decades. Airport development will be subject to annual review by the Corps and the Airport. The Airport has agreed, as one condition of the permit, to hold pre-construction meetings with the Corps and resource agencies prior to any clearing or fill in the permit area.
Several conditions contain provisions for community review of planned developments.
In turn, the Airport will have the ability for long-term planning over the next decade. Expected demand for increased international cargo movements with Anchorage as a hub is a major part of the future plans of the Airport. Other effects of increased use of the airport property studied by the Corps included effects on traffic and noise in the area. There are a total of thirty conditions of the Airport permit, the Corps said.
