Tri-Cities Airport: No Trespassing on Airport Property

​Residents should note that trespassing is forbidden on Tri-Cities Airport (PSC) property. The area located at the northeast end of Runway 12/30, more commonly known as “20 Dead Cows,” is closed to public access, and has been since 2017. Despite the closure, people continue to use this area for ORV use, firearms practice, and other recreational pursuits, in violation of the No Trespassing ordinance and the road closures. 

As a result of this criminal activity, the airport property is being damaged daily, placing an undue financial and liability burden on the airport. PSC staff has erected gates and other barriers across all major access points, posted signage, and taken other steps to prevent trespass. Because of the continued illegal activity, police patrols will be increasing, and anyone found on airport property will be subject to arrest for trespass. Please help airport staff by respecting the signs and our property.
