Buchanan Fields Golf Course Tree Trimming
Concord, CA · near Buchanan Fld (0.8 mi)
What this outcome means
The FAA sent the case back to the filer rather than issuing a determination. This is the most common non-clean outcome and usually means something has to change or be supplied before the study can finish — not that the project was refused.
The proposal, in the filer's words
"Trimming of existing trees located on Buchanan Fields Golf Course property adjacent to Buchanan Field Airport situated within the Runway 1L approach corridor. The subject trees currently exceed acceptable height limitations and penetrate the protected airspace surface creating potential obstructions to instrument and visual approach procedures. All trees will be reduced to a maximum height of 14 feet above ground level (AGL) to restore compliance with FAA obstruction clearance standards and maintain a clear Obstacle Free Zone (OFZ) along the extended runway centerline. A scissor lift will be deployed on-site to safely elevate crew members to the required working height enabling precise canopy trimming in accordance with the project's vertical clearance specifications."
