Addison Airport Receives $1,475,000 TxDOT Grant

The Addison City Council formally accepted a grant from the Texas Department of Transportation (TxDOT) Aviation Division in the amount of $1,475,000 at its July 14 meeting. The grant will fund a runway designation change and the application of surface preservation treatments to the runway, and various taxiways.

Runways are designated by a number from 1 to 36, which is the magnetic heading of the runway in degrees, divided by ten. A runway numbered 9 points east (90°), runway 18 is south (180°), runway 27 points west (270°) and runway 36 points to the north (360° rather than 0°). Changing the runway designation requires repainting the runway designation numbers at both ends of the runway, along with replacement of numerous airport guidance sign panels. Additionally, it requires changes in the Federal Aviation Administration (FAA) aeronautical charts, approach plates, airport diagrams, the airport's master record.

The grant also includes funds for the application of surface preservation treatments. Asphalt surface treatments are a preventative maintenance procedure applied to the asphalt surface to seal and protect the asphalt pavement from environmental conditions such as sunlight and rain. Surface preservation treatment will be applied to the runway, Taxiway Alpha, and the asphalt connecting taxiways (Charlie, Delta, Echo, Foxtrot, Golf, Hotel, and Juliet). 

The $1,475,000 grant amount will be a 100% grant with no local matching funds required. Any costs incurred over the grant amount will be subject to the usual 90%-10% split requiring a 10% matching share from the airport (with the 90% being the Federal/State grant share).
