A city park adjoining Gig Harbor City Hall will close for about a month to remove more than 20 trees infected with laminated root rot.

The city said Tuesday that Grandview Forest Park, located at 3448 Grandview St., will close on Aug. 17. The neighboring skate park will also close temporarily Aug. 29 when two trees are cut down there.

An arborist identified laminated root rot in approximately 25 trees at the 8-acre park. The native fungus primarily infects Douglas fir trees. It weakens the structural root system, killing trees from the ground up. It can result in trees falling or blowing over at any time.

Laminated root rot is no stranger to the Peninsula. It forced the closure of Kopachuck State Park in 2011, where the state removed hundreds of infected trees.

For every tree removed at Grandview park, two will be replanted, project engineer Marcos McGraw said. Cedar trees and other pine trees not susceptible to the rot will be planted, he said. The trees will not be planted until the fall, when they have a better chance of survival.

The park should reopen around Sept. 20, according to the city.
