(a) The acquisition and maintenance of land for wetlands mitigation, wetlands banking, natural habitat, or other appropriate environmental mitigation is an eligible cost under the Federal-aid program. FHWA participation in wetland mitigation sites and other mitigation banks is governed by 23 CFR part 777.
(b) Environmental acquisitions or displacements by both public agencies and private parties are covered by the Uniform Act when they are the result of a program or project undertaken by a Federal agency or one that receives Federal financial assistance. This includes real property acquired for a wetland bank, or other environmentally related purpose, if it is to be used to mitigate impacts created by a Federal-aid highway project.
