Only one of three ballfields Auburn’s Game Farm Park is in the dark when the sun goes down.

But, not for much longer.

On Monday, the Auburn City Council authorized Mayor Nancy Backus to execute an agreement between the city and King County that will net the city a $175,000 grant to help light up that field.

City officials call the pending work at Game Park “a capacity project that will significantly increase playability for different sports, while taking pressure off of other park facilities.”

Daryl Faber, director of Auburn Parks, Arts and Recreation, said the field, the one farthest from the parking lot, is predominantly used as a softball field but other sports, including soccer, are also played there.

“Without lighting there, soccer can’t be played on that field after dark in the winter, and soon it will,” Faber said.

The city estimates the total project cost at $387,213, and the city anticipates funding to shake out as follows:

• Local funds, (park impact fees): $215,000, 56 percent of the total cost; and

• King County grant: $175,000, 44 percent of total cost.

King County manages the Youth and Amateur Sports Fund.
