Episode Summary In this episode, Dan Medeiros – senior field representative for The Conservation Fund – discusses mountain lion conservation efforts in California as it relates to transportation infrastructure construction, motorist and wildlife safety, along with helping improve ecosystem linkages. Episode Notes In this episode, Dan Medeiros joins The Stream by AASHTO to discuss his work with The Conservation Fund – a 40-year-old organization that purchases land across the US to preserve wildlife habitat – and its efforts in California to support the safety and growth of mountain lion populations and their habitats. Medeiros discusses how mountain lion conservation efforts interconnect with transportation infrastructure needs; especially how large barriers and quick-moving cars are two of the main culprits behind mountain lion deaths. He also points to specific examples, including the death of “54M” – a mountain lion tracked by that The Conservation Fund that was tragically killed by a vehicle when trying to cross a major highway. Medeiros also explains the importance of stakeholder input on large infrastructure projects that involve mountain lion populations, including state departments of transportation, local residents, and private organizations. He provides input on the importance of quality data collection, advocacy, and conversation when working with big stakes.

As a result, cycling became a mainstream mode of transportation in Seville, reshaping public spaces and changed how residents view urban mobility.

Episode Summary The latest episode of the “The Stream by AASHTO” podcast features Garrett Eucalitto, commissioner of the Connecticut Department of Transportation and the 2024-2025 president of the American Association of State Highway and Transportation Officials, discussing his commitment to “safer communities, safer users, and safer workers” and federal surface transportation reauthorization as part of his emphasis areas for his one-year presidential term. Episode Notes This podcast series is part of the AASHTO Environmental Management technical service program operated by the American Association of State Highway and Transportation Officials and it explores a wide array of environmental topics that affect state departments of transportation and the infrastructure programs they oversee. In this podcast episode, Eucalitto delves into his family’s connection to the transportation industry, how his career path shifted from foreign relations to transportation policy, and why he’s made “centering safety” a key focal point not only for his AASHTO presidential emphasis areas but as the nucleus of his transportation career. He also discusses the critical importance of ongoing surface transportation funding reauthorization work by Congress and how that legislative effort impacts safety. He explains on the podcast that reauthorization “impacts everything we do” as state DOTs, especially in the safety arena. That’s why it is critical to ensure that the current reauthorization package maintains – if not expands – the current level of federal funding to fully support the nation’s transportation systems. Eucalitto is also AASHTO’s first openly gay president and discusses how this part of his identity has helped make him more empathetic about protecting people physically, mentally, and emotionally – especially in terms of fostering a level of comfort so people can live openly in the workplace. Finally, Eucalitto looks to the future as part of his podcast interview – examining the ways state DOTs are seeking to broaden their “non-traditional” partnerships, along with ways state DOTs are working to improve the exchange of information between one another for disaster response and other needs.

Episode Summary The latest episode of the “The Stream by AASHTO” podcast features Ted Boling, a partner with Perkins Coie, with over 30 years of public service – who discusses recent changes to the National Environmental Policy Act, or NEPA, and the removal of regulations by the Council on Environmental Quality, or CEQ. Episode Notes This podcast series is part of the AASHTO Environmental Management technical service program operated by the American Association of State Highway and Transportation Officials. It explores a wide array of environmental topics that affect state departments of transportation and the infrastructure programs they oversee. In February 2025, the CEQ announced an Interim Final Rule that removes its longstanding NEPA implementing regulations from the Code of Federal Regulations. This shift places the responsibility for NEPA compliance directly on individual federal agencies, allowing them to follow their own procedures rather than a centralized set of rules. In this podcast episode, Boling delves into how, if NEPA is revoked, it removes a “universal framework” that will prevent federal agencies working in tandem on environmental reviews. Boling also outlines the potential impact of mass layoffs within the federal government, especially among senior leadership and recent hires, and how that could slow down decision-making regarding environmental reviews for infrastructure projects.
