The goal of the 2021 - 2022 COAR grant application was to establish runway lights, making this airstrip the only Central Oregon Cascade airport to have lighted nighttime landing availability. As of the spring of 2023 this is a reality.
Late summer of 2023 also saw the fencing/security of the airport, reinforcement of the helicopter landing pad and gravel to reduce the impact of dust to aircraft of all types.
