Concrete removal in Rainier Valley
We are a Seattle concrete removal referral service. Tell us what needs to go and we'll connect you with one local concrete removal company — not five.
Rainier Valley is not a river valley. HistoryLink describes it as the low land between two ridges, running about seven miles southeast from downtown to Lake Washington. Two of the City's principal arterials run its length, Rainier Avenue South and Martin Luther King Jr Way South, and much of the low ground is mapped by the City as liquefaction-prone.
Both facts shape a concrete removal here: where the dumpster can sit, and what the ground under an old slab may be doing. If you would rather someone else sorted it out, we pass your details to one local concrete removal company, and there is no charge to you.

Staging a dumpster on a valley street
SDOT requires a Street Use permit before a dumpster or storage container is placed in the public right-of-way. For residential use the container should sit in a legal parking space in front of your property, free-standing, and at least 30 feet from an intersection, 10 feet from a driveway and 15 feet from a hydrant. To hold the space, you set up a temporary No Parking zone and post the notice at least 72 hours ahead.
The rules tighten on bigger streets. SDOT says a construction container on any arterial street needs a Right-of-Way Construction Use permit instead of the simpler residential one. SDOT's own corridor study calls Rainier Avenue South a principal arterial carrying around 20,000 vehicles a day, and names Martin Luther King Jr Way South as a principal arterial too. A house that fronts either one is a different permit job from a house on a side street.
- Street Use permitting: (206) 684-5253 or SDOTPermits@seattle.gov.
- Moving trucks do not need this permit; containers and dumpsters do.
- If the only free space is in front of a neighbor's property, SDOT says you must notify them first.
Low ground, soft ground
By our overlay of the City's critical-area maps on the Rainier Valley district boundary, which on the City's map takes in Mount Baker, Columbia City, Brighton, Dunlap, Rainier View and Rainier Beach, about 18% is mapped liquefaction-prone and about 3% peat-settlement-prone. About 8% is mapped steep slope.
SDCI describes peat-settlement-prone areas as sites with peat and organic soils that may settle when the area is developed or the water table is lowered. Liquefaction-prone areas are loose, saturated soils that lose strength in an earthquake. In both, SDCI's grading page uses the standard citywide permit thresholds, such as adding or replacing 750 square feet or more of hard surface.
Housing that came in waves
HistoryLink traces the valley's growth to the Rainier Avenue Electric Railway, which reached Columbia City by 1891 and ran down the middle of Rainier Avenue until 1937. During World War II the federal government built thousands of low-cost temporary units at Rainier Vista, Stadium Homes and Holly Park.
Today the south end is mostly owner-occupied houses: in the City's Rainier Beach community reporting area, 70.3% of housing units are single detached homes and 68% of households own, per the 2020-2024 American Community Survey data the City publishes. In Mt. Baker/North Rainier it is 58.9% detached. For a Columbia City address inside the landmark district, see that page first, because approval comes before permits there.
Questions about concrete removal in Rainier Valley
Do I need a permit for a dumpster in Seattle?
When it goes in the street or parking lane, yes. SDOT requires a Street Use permit before a dumpster or portable container is delivered and placed there. On an arterial street, a construction container needs a Right-of-Way Construction Use permit.
How far from a driveway or hydrant must a dumpster be?
SDOT's guidelines say at least 30 feet from intersections, 10 feet from driveways and 15 feet from hydrants, in a legal parking space and free-standing.
What does peat-settlement-prone mean?
SDCI describes these as sites containing peat and organic soils that may settle when the area is developed or the water table is lowered. They are one of the environmentally critical areas shown on the City's GIS map.
How much notice do I need for a temporary No Parking zone?
SDOT says to post the public notice on the No Parking easels at least 72 hours before placing the container.
