Parks, Natural Areas Preservation - As enacted, designates segments of the Buffalo River, Duck River, and certain other rivers and creeks as Class II pastoral river areas; expands certain public outreach requirements concerning scenic rivers. - Amends TCA Title 11, Chapter 13.

HB 1510 designates specific segments of the Buffalo River, Duck River, and four creeks (Beaverdam, Lick, Piney, and Swan) as Class II pastoral river areas under Tennessee law. This directly affects communities and landowners near these waterways, particularly in Hickman, Williamson, and Dickson counties, by establishing new protections for their natural landscapes. The bill expands existing protections by including the entire Buffalo River (previously excluding some counties), the entire Duck River except the Normandy Reservoir segment, and adding the four new creek segments to the designated areas. It also broadens public outreach requirements to apply to "any river" instead of just the Duck River, requiring more community engagement for scenic river management. These changes aim to preserve the natural character of these waterways through formal legal designation.
