This handbook provides an overarching view of the ecosystem and eco­nomic benefits and cost savings associated with progressive approaches to the Clean Water Act or Endangered Species Act compensatory mitigation and com­pares these benefits and savings to traditional mitigation approaches. Several empirical examples of transferable tools, models, and frame­works used for innovative compensatory mitigation in use throughout the United States are provided.  Innovative tools, methods, and frameworks are also provided on :

  • landscape or watershed analysis of ecosystem functions
  • progressive approaches that include the valuation of ecosystem services pro­vided by compensatory mitigation.

Finally, tangible steps are suggested for trans­portation agencies, policy-makers, and the research community to facilitate and implement suggested progressive mitigation programs.
