Reduce flooding by keeping storm drains clear of leaves | Pierce County

Pierce County residents can reduce flooding on county roads by picking up yard waste on their properties and making sure nearby storm drains are free of leaves.

Pierce County residents can reduce flooding on county roads by picking up yard waste on their properties and making sure nearby storm drains are free of leaves.

“The potential for flooding along county roads increases as wet weather returns and leaves fall,” said Brian Ziegler, Pierce County Public Works director. “Leaves and debris can block storm drains, resulting in roadway flooding. We encourage residents to pick up yard waste and remove leaves and debris blocking neighborhood storm drains throughout the fall.”

Pierce County residents can take the following actions to keep storm drains clear:

· Put leaves and other yard debris in yard waste bins for pick up. Find transfer stations where you can drop off yard waste at

· If it can be done safely, remove leaves from storm drains with a rake.

· For Pierce County roadways: If a blockage can’t be cleared, the roadway is flooding or a storm drain is on a busy road, call Pierce County Public Works at (253) 798-6000 or submit a Request for Action at

Residents in cities and towns should contact their local public works department to report flooding or storm drain problems.

Roadway flooding response

Significant rainstorms may cause roadside storm drains and ditches to overflow and flood the roadway. River flooding may also affect roads. As the rain saturates the ground, there is also an increased risk of downed trees and landslides.

Pierce County road crews clear drainage systems, downed trees and landslides when possible, close roads or lanes if they are not passable, and clean drainage systems proactively to reduce flooding.

Motorists should not drive through standing water, near downed trees or utility lines, or around road closure barricades.
