Determination of no hazardDetermined - No Hazard4 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

"Proposing to install a wooden fence along a new portion of the Farmington Canal Heritage Trail a multi-use public recreation trail. The three-rail wooden fence will be 4 feet tall and placed on portions of the trail with downward slopes on either side. The fenced portion of the trail shown in the figure is not on airport property. Points 3 4 and 5 are within the area released from the airport and are not on airport property (see attached land release letter and area)."
