Alaska Highway Case Study: Heat Transfer, Permafrost Degradation, and Transportation Infrastructure Stability
2011
The Alaska University Transportation Center (AUTC) of the University of Alaska, Fairbanks, has supported multiple projects to research measures to reduce permafrost thaw and the resulting impacts to roads, specifically along the Alaska Highway (the only road connecting Alaska to the continental U. S. ). Structural damage occurs when the permafrost under road infrastructure thaws. Thermal modeling demonstrates that the stability of permafrost below roadways and embankments is greatly affected by surface temperatures of roadways, and it has therefore been predicted that as the climate warms, permafrost degradation will be a major issue for the design and maintenance of roads in Alaska.

Winslow Way Street Redesign (Bainbridge Island, WA)
2011
The City of Bainbridge Island redesigned its main downtown street to update aging water infrastructure, improve walkability and multimodal uses, and better manage stormwater using more natural and vegetated solutions. The new design is more walkable and accessible, supports biking, better manages stormwater with green infrastructure practices, and encourages social cohesion through smart design. Over half a mile in length, this innovative redesign protects street trees and incorporates stormwater planters, rain gardens, and other methods to retain stormwater and prevent flooding.

Improving Drought Preparedness in the West
January 2011
The Western Governors' Association and Western States Water Council convened a series of workshops to engage constituents in evaluating progress in drought preparedness. The workshops brought together end-users of drought information from a variety of sectors, including agriculture, energy, navigation, water supply, cultural resources, and the environment. Attendees included representatives of states, federal agencies, tribes, local governments, non-governmental organizations, and the private sector.

America’s Climate Choices: A Conversation on America’s Climate Choices
2011
The report, 'A Conversation on America's Climate Choices,' is the final volume of the America’s Climate Choices suite of activities - a series of five studies requested by Congress. This report gives an overview of the nation’s options for responding to climate change impacts through broad adaptation strategies. The document offers advice on how to weigh the potential risks and benefits associated with different actions that might be taken to respond to climate change, and how to ensure that actions are as effective as possible.

Direct Potable Reuse: A Path Forward
2011
This report identifies the information and research needed to provide a basis for the feasibility of direct potable reuse (DPR), which is the introduction of purified water into a water supply distribution system or the raw water supply immediately upstream of a water treatment plant. Topics discussed include issues regarding public acceptance, engineering, economics, and regulations. Although the background information on DPR and the needed research identified in this report are applicable across the country and throughout the world, the primary focus is on providing information so that the feasibility of DPR can be evaluated in California.

Northwoods Climate Change Response Framework
2011
To address climate change impacts on northern Minnesota, Michigan and Wisconsin forests, the ‘Northwoods Climate Change Response Framework’ was established in 2011. The project has involved more than 40 scientists and natural resource professionals collaborating to assess the vulnerability of forest ecosystems to climate change – developing the Framework for resource management, conservation, and collaboration in adaptation planning.

Delaware Estuary Living Shoreline Initiative
From the Partnership for the Delaware Estuary (PDE), the Delaware Estuary Living Shoreline Initiative (DELSI) is a pilot project designed to stabilize eroding shorelines of tidal marshes. PDE with Rutgers University has developed the "DELSI Tactic" of living shorelines which uniquely uses a combination of native wetland plants, natural structures, and intertidal shellfish to trap sediment and absorb waves. The DELSI Tactic provides an economical approach to communities that are struggling to combat the erosion of tidal marshes.

Michigan Cost-Benefit Model Evaluation of M222 Slope Stabilization
2011
The Michigan Department of Transportation (MDOT) tested a National Cooperative Highway Research Program (NCHRP) cost-benefit model to evaluate the cost-effectiveness of a roadside slope stabilization project in light of future temperature and precipitation projections. The road, which is located on a portion of route M-222 along the Kalamazoo River in the City of Allegan, has a slope that has already experienced erosion caused by intense precipitation and flooding. MDOT was in the process of stabilizing the slope using structural measures, rather than vegetative or other “soft” approaches.

Virginia Living Shorelines Initiative
2011
Virginia Marine Resources Commission (VMRC) was directed by SB 964 in 2011 to develop and implement a general permit regulation that authorizes and encourages the use of living shorelines as the preferred alternative for stabilizing tidal shorelines. In 2015 and again in 2017 the VMRC established permitting regulations pursuant to SB 964. The Living Shoreline Group 1 (2015) and 2 (2017) General Permits for Certain Shoreline Treatments are regulations which streamline the permitting process incentivizing property owners to utilize a living shoreline approach to manage shoreline erosion, and promote tidal wetland vegetation to restore or enhance ecosystem services.

Natural Resource Defense Council: Rooftops to Rivers II
2011
From the Natural Resource Defense Council (NRDC), Rooftops to Rivers II describes the challenges of managing stormwater, and the benefits and economics of employing green infrastructure to do so. The report explains how population growth, changing landscapes, aging infrastructure, and climate change are placing increasing pressures on stormwater management. Highly detailed case studies are developed for 14 cities that are all leaders in employing green infrastructure solutions to address stormwater challenges.
