Determination of no hazardDetermined - No Hazard15 ft AGL

What this outcome means

The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.

The proposal, in the filer's words

"Upgrade sidewalks around Washington County Courthouse area includes sidewalks along Hwy 8 North Missouri Street and Breton Street. Replace sidewalks on courthouse property and upgrade to ADA standards. Install 5'-wide or wider in some areas concrete sidewalk & curb at street level around the entire outside edge."

Screening a structure of your own?

Check Part 77 and the tower's line of sight before you file

LOS Analyzer screens a proposed structure against FAA Part 77 surfaces and the control tower's sightline to the runway, terrain-aware, in minutes. It is a preliminary screening — not an FAA determination and not a substitute for a licensed engineering review.
