The Local Government Lab is an annual symposium held by the Rockefeller Institute of Government. This is the presentation materials (slide deck) and supporting materials (transcript, image descriptions, and plain language summary) from Dr. Kaitlin Stack Whitney's presentation at the 2022 Local Government Lab, titled: "Tradeoffs in transportation ROW uses: examples of US states exploring solar energy, agriculture, and pollinator habitat along roadsides." Video link: https://www.youtube.com/watch?v=JTV6K8dRuow Abstract: Helping wildlife cross or avoid highways has a recent focus in transportation planning and innovation, as shown by its inclusion in the 2021 federal legislation Infrastructure Investment and Jobs Act (Public Law No: 117-58) recently passed in the United States (US). Yet state and municipal governments across the US are also using highway rights-of-ways (ROW) as potential sites of conservation, as well as other environmentally-friendly purposes. As part of my ongoing Richard P. Nathan Public Policy Fellowship at the Rockefeller Institute of Government, I present research in progress on state and local examples of innovative uses of roadside ROWs. I examine three innovative ROW uses (solar energy arrays, pollinator plantings, and agriculture), including both a snapshot of known US states piloting or carrying out these initiatives and case examinations of specific highways and localities trying them out. Additionally, I explore the historical context, economic and legal considerations, and potential tradeoffs - with discussion of how they may scale to other regions and US states. Plain language summary: Along many roads, there is other land the state owns. This land helps people and cars to be safe, by being a place to pull over or making it easier to see animals that may try to enter the road. Some states are thinking about what else they can do with this land next to roads. They may want to make changes to save or raise money. While they can make some changes, the top need is for people to be safe. For some of my work, I am looking into three of the ways states may want to use this land. The first is using the sun to make power in the land on the side of the road. Some states are already doing this but most are not. Using the land to make clean power can save money for states and help power their cars. The second is to grow plants on the side of the road. Some states a...
