On August 29, the U.S. Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (Army Corps) issued a final rule amending the 2023 definition “Waters of the U.S.” (WOTUS) to conform with the U.S. Supreme Court’s (SCOTUS) decision in Sackett v. EPA. The amendments made by the EPA and the Army Corps (the agencies) remove or elements of the definition that are invalid under the Sackett decision, including the significant nexus test and the definition of ‘adjacent.’ Join NACo for a discussion of the amendments made by the agencies and the future of WOTUS.

FAA-NACo Airport Land Use Compatibility
Wednesday, December 10, 2025 | 3:00 p.m. - 4:300 p.m. ET
Counties play a crucial role in our nation’s aviation system, owning and operating hundreds of airports across the country. And even in places where the county may not own the airport, county planning departments and development organizations work to maximize the value of this asset to the community’s economic and overall wellbeing. Join NACo and staff from the Federal Aviation Administration (FAA) Office of Airports Planning and Programming to learn more about the FAA’s “Advisory Circular on Airport Land Use Compatibility Planning,” which will enable counties work smarter to integrate airports into broader planning efforts for land use, economic development and more. FAA staff will also be available to answer questions from county leaders about planning needs in their community and how the Advisory Circular can guide those efforts.
