Determination of no hazardDetermined - No Hazard100 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

"The new construction is 100' tall at the tallest point and is approximately 577 feet long and 322 feet wide. It is oriented along the long axis in the NW/SE direction with the corners of the structure at coordinates LAT 39d 04' 14.20\/LON 77d 30' 37.46\"; 39d 04' 11.90\"/77d 30' 40.22\"; 39d 04' 08.59\"/77d 30' 36.00\"; 39d 04' 10.72\"/77d 30' 30.03\". The building is a steel structure with Precast Concrete exterior walls and exposed steel 3 story mechanical yard with a metal panel screen wall.""

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.
