AGENDA CAPTION:

Consider Action on a Resolution to Approve Acceptance of an Airport Improvement Program (AIP) Grant Offer from the Texas Department of Transportation (TxDOT) in the Amount of $1,475,000 for Changing the Runway Designation from 15/33 to 16/34 and Applying Surface Preservation Treatments to the Runway, Taxiway Alpha, and the Asphalt Connecting Taxiways Charlie, Delta, Echo, Foxtrot, Golf, Hotel, and Juliet; Designating TxDOT its Agent for Receiving and Disbursing Funds; Acknowledging that Addison will be Responsible for a Potential Estimated Contribution and to Authorize the City Manager to Execute all Necessary Documents to Accept the Grant from TxDOT.

BACKGROUND:

This item is to accept a grant from the Texas Department of Transportation Aviation Division in the amount of $1,475,000, for the runway designation change and for the application of surface preservation treatments to the runway, and various taxiways. 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). The airport's fiscal year 2020 capital budget included 10% matching shares totaling $191,060 for the runway re-designation and surface treatments. It is unlikely that more than a small fraction of the available matching funds will be required for this project.

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 of 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 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. Untreated, the existing asphalt surface will begin to deteriorate due to oxidation and infiltration of water. Surface preservation treatment will be applied to the runway, Taxiway Alpha, and the asphalt connecting taxiways (Charlie, Delta, Echo, Foxtrot, Golf, Hotel, and Juliet).

RECOMMENDATION:

Administration recommends approval.
