356th Drive SE new vehicle weight limits.
March 18, 2020 - New vehicle weight limit increases to 15 tons during dry weather.


King County Road Services is closely monitoring ground movement on 356th Drive SE near Fall City, where a slow-moving slide is taking place under the roadway. On February 10, Road Services, in partnership with the Office of Emergency Management, issued a voluntary evacuation message to residents who would be cut off if conditions worsen and the road washes out. The county does not expect the slide to affect State Route 202.

Frequently-asked questions

Yes. On Thursday, March 18, King County raised the vehicle weight limit on 356th Drive SE from five tons to 15 tons—but only when the ground is dry. The weight limit remains five tons during rainy weather and for 48 hours after it stops raining.
A changeable weight limit sign will be posted at the slide area. Road crews will adjust the sign to display either the five-ton or 15-ton limit. Road Services will also update this website and send a notification to the project email distribution list when the vehicle weight limit is decreased to five tons or increased to 15 tons.
Increasing the vehicle weight limit to 15 tons allows heavier service delivery trucks such as propane and garbage trucks to access residences.
Soil experts have determined the road can handle vehicles weighing up to 15 tons when the soil beneath the road is dry (having absorbed less than one inch of precipitation). For safety, the weight limit will change back to 5 tons during wet weather and for the 48 hours after rain stops.
The weight restriction is in place to prevent the road from sliding—or failing completely. King County may remove the 15-ton (dry weather only) limit if slide movement increases during use by heavier vehicles.

Garbage service
Garbage service remains up to residents to self-haul to collection sites because of the prohibitive weight of the trucks. The two sites nearby are located in Factoria and Cedar Falls:

Recycling service
Recycling service also remains up to residents to self-haul to collection sites. Self-haul recycling at King County transfer stations is free! Please note one key difference from recycling in your curbside bins at home: separate clean corrugated cardboard boxes from the rest of your recyclables. Other regular recyclable material can be placed in the container labeled “Recyclable Materials” at all transfer stations.

  • Corrugated cardboard must be empty and flattened. Please no Styrofoam, plastic film, or packing peanuts.
  • Accepted recyclable materials include the below. As with curbside bins, recyclable materials must be empty, clean, and dry. Keep items loose – do not bag recycling, and no plastic bags please.
    • Paper, including office paper, junk mail, envelopes, newspapers, magazines, catalogs, paperboard food boxes (like cereal and pasta boxes)
    • Plastic bottles, jugs, tubs, cartons, cups, and other plastic containers, including large lids (3” or more)
    • Glass bottles and jars
    • Metal cans

King County is working with a team of soil experts (geotechnical engineers) to determine the type of repairs needed. We expect to publish a timeline for road repairs in spring 2020. Please check back in late April or early May for more information.
It will take approximately three months to design the repairs and another three to six months to acquire the necessary permits and property use agreements that need to be in place before actual road construction can begin. We are working to shorten and compress the design and permitting process as much as possible. Actual construction could take up to three months or longer, depending on the type of repairs needed.
We may be able to keep the road open during repairs. We are working with a team of geotechnical engineers to determine if it is possible. More information will be posted to this website in spring 2020.
356th Drive SE provides the only access for some 75 homes. The road is currently open but restricted to one lane north of the 4000 block. The ground under the roadway is moving slowly. Heavy rainfall could accelerate the slide and wash out the road.
Residents who live north of the 4000 block on 356th Drive SE are encouraged to leave the area. Those who live or work south of the 4000 block are not affected at this time.
Residents should consider leaving the area as soon as possible. If road conditions worsen and the road is closed or becomes inaccessible, there may not be another consistent way in or out of the area.
