Road Closures

Currently, Mill Pond Road and SE Reinig Rd at the Snoqualmie River Trestle are temporarily closed. Do not drive through water or around road barriers.

Storm Drains and Pooling Water

During heavy rainfall, residents can help prevent water from pooling in local streets by keeping storm drain entrances clear of debris, including leaves and tree branches. Storm drains help to quickly move water off roads preventing dangerous driving conditions.

Parking
Residents in areas that experience higher waters during early flood stages are advised to move vehicles to higher ground, such as the parking lot by Snoqualmie Community Park, 35016 SE Ridge St (next to the YMCA).

Sandbags Available as Needed
Residents or businesses that need sandbags now or for future flooding can get them at the Public Works Facility, 38910 SE Stearns Road (near the Tokul Roundabout and Mill Pond Rd).

The King County Flood Control District has supplied sand and sandbags for Carnation residents at the City’s Public Works Maintenance Shop, located at 33100 NE 45th Street.

These sandbag supplies are limited and available on a first-come-first-serve basis following a declared flood warning announcement.  The supplies to make your own sandbags are available from 8:00 AM to 3:30 PM, Monday through Friday.  There is a 50 bag limit per household. 

The Snoqualmie Emergency Management Department is continuing to monitor river flow changes.

*As defined by the United States Geological Survey (USGS), cubic feet per second (CFS) refers to the rate of the flow in streams and rivers. It is equal to the volume of water one foot high and one foot wide flowing a distance of one foot in one second. One cfs equals 7.48 gallons of water flowing each second.
