This report presents a discussion of the source water watersheds for Little Rock, Arkansas, and its environs: Lake Winona and Lake Maumelle Watersheds. This report includes a description of each watershed’s current health, threats to water quality, and the ecosystem services benefits that the watersheds provide. In addition, we provide estimates for the economic value of these natural capital assets. By shedding light on the importance of these watersheds to the economic health of the region, these estimates provide the foundation for better-informed decisions regarding watershed management activities.
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.
This report evaluates the costs and benefits of floodplain protection in Waterbury, Vermont and Willsboro, New York in the Lake Champlain Basin, U.S.A. The primary elements of the project are ecosystem services valuation, buildout/conservation analysis, hydrologic calculations of current existing peak flows and predicted future peak flows, hydraulic modeling of floodplains, building damage simulations due to flooding, and cost-benefit accounting to determine the best form of flood risk reduction for each community. The most economically sound flood risk mitigation plans were found in towns in which damage reductions were high, the loss of tax revenue was low, the cost of mitigation activity was low, and the ecosystem service value was high.
This report examines the growing risks and rising costs of climate change across the United States. Hurricanes, floods, and extreme weather events have high human and financial tolls. This report calls for increased efficiency and effectiveness in natural hazard management through proactive investments and a focus on green infrastructure for risk reduction. The report also identifies seven areas of federal and state law in need of improvement.
