This report evaluates the effect that calculating environmental benefits could have in two flood and stormwater mitigation case studies in Wisconsin: the first, a partially-funded property acquisition project in Jefferson County; the second, a stormwater mitigation project in the City of Portage. Integrating environmental benefits into hazard planning will enable local and state floodplain and emergency management professionals and stakeholder groups to use FEMA policy updates on benefit-cost analyses to fund innovative flood-risk reduction projects.
