A drainage project at the Port of Grays Harbor’s Bowerman Airport will require the airport to be shut down for two months this summer.

The Federal Aviation Administration (FAA) is requiring the closure of the airports’ runway, main taxiway, fuel island, and apron from July 8, 2019 through Sept. 4, 2019.

The project includes the regrading of the runway and taxi shoulders. The area between the runway and taxiway will also be regraded to move water away from those surfaces. Much of the drainage infrastructure will be removed and replaced with catch basins. Existing outfalls will be cleaned and repaired as necessary.

Once the project is complete, the area will be seeded and returned to a grass-covered surface. Edge lighting along the runway will be replaced and the segmented navigation circle will be repaired. The improvements should “drastically reduce the frequency, amount, and duration of surface water at the airport,” according to a press release from the port.

“We apologize in advance for any inconvenience the closure may cause to our aviation community, both locally and beyond,” Business and Trade Development Assistant Shannon Anderson said in a statement. “We appreciate everyone’s patience and understanding during construction and we are confident the drainage project improvements will be a benefit for Bowerman Airport users for decades to come.”

The work is being done by local contractor Rognlin’s, Inc., at a cost of $2.4 million. The cost will be shared by the FAA, Washington State Department of Transportation Aviation, and the port.

The project is the fourth phase of a five-stage project started in 2013. The final phase is scheduled for 2023 and will combine drainage improvements with resurfacing of the aprons and taxiways around the hangars.
