Cojo installs extruded and poured concrete curbing across the 97338 zip code -- Dallas, Oregon and the surrounding Polk County area. Most local jobs are subdivision drainage curbs, parking-lot perimeter curbs along Highway 22, and retrofit work where old concrete curbing has spalled from freeze-thaw cycling. Pricing depends on linear footage, curb profile, and access, but most residential and small commercial scopes land within the published baseline range below.
Concrete Curbing in Dallas, Oregon -- What the Local Work Looks Like
Dallas is the Polk County seat, and the 97338 footprint covers the downtown grid, the Highway 22 retail corridor, and a steady ring of new-build subdivisions on the south and east sides of town. That mix drives three distinct curbing scopes. Downtown grid work tends to be repair-and-replace -- patching ADA cuts, replacing spalled gutter pans, and aligning new curb to existing sidewalk. Highway 22 retail work is heavier: shopping center perimeters, drive-through curbs, and trash-enclosure aprons that need to handle truck wheel loads. The newer subdivisions on the south side are pure new-construction extruded curb -- continuous machine-formed runs to channel stormwater toward catch basins.
Polk County stormwater rules treat curbing as a drainage system component, not just a parking-lot edge. That means the curb profile, the back-of-curb slope, and the spacing of weep cuts all matter to plan review. Dallas city permits for commercial work follow the county template. Cojo handles permitting on commercial scopes by default and quotes residential drainage curb without permits when the work stays inside a private lot.
Curb Types We Install in 97338
Most jobs in this zip fall into one of four curb types:
- Extruded curb (machine-formed) -- the workhorse for parking-lot perimeters, subdivision streets, and long drainage runs. A specialized curb machine extrudes a continuous concrete profile in one pass. Fast, consistent, and the most cost-effective option for runs over 100 feet.
- Poured-in-place curb and gutter -- used where the curb has to tie into a sidewalk apron, an ADA ramp, or a complex transition. Wood or metal forms set the shape, then crew hand-trowels the finish.
- Mountable rolled curb -- common in Dallas subdivisions where homeowners need to drive across the curb to access their driveway. Lower profile, gentler slope.
- Decorative or colored curb -- occasional retail and HOA work where the curb doubles as a visual divider for landscape beds. Pigmented mix or stamped finish.
The right type depends on what the curb has to do. A drainage curb behind a new home needs a sharper back angle than a parking-lot perimeter curb. We size and spec the profile during the on-site walkthrough.

Current Market Reality
The published ranges assume a clean site, easy machine access, and a single mobilization. Dallas jobs that fall outside those assumptions get more expensive fast. Tight downtown alleys force hand-trowel work where the curb machine would normally run. Subdivisions on rolling Polk County ground need over-excavation for unstable subgrade. Fuel costs to mobilize a curb machine from Hood River or the Salem yard show up in any quote under 300 linear feet. Concrete mix prices have moved sharply over the last two years, and any quote older than 30 days should be re-validated before signing.
Freeze-Thaw and Polk County Subgrade
Dallas sits at about 325 feet elevation with 45-55 freeze-thaw days a year, which is the band where curbing failures get expensive. Water gets into a hairline crack at 35 degrees F, expands when it freezes overnight, and pries the crack wider every cycle. A curb that was tight in October can be spalling by March. The mitigation is straightforward but easy to skip: an air-entrained concrete mix (5 to 7 percent entrained air), a proper subgrade compaction, and a control joint every 10 feet on extruded runs. We spec these on every Polk County job. If your existing curb is failing from freeze-thaw, replacement usually beats patching -- a patched curb cracks again at the cold joint within two seasons.
Polk County soil in the Dallas footprint is mostly Willamette silt loam over basalt -- decent bearing capacity but holds water in the rainy season. Subdivision drainage curbs along the new-build edges of town carry real stormwater volume from October through May. Sizing the gutter pan right matters here; a 6-inch pan that works in Bend will overflow on a 1-inch rain event in Dallas.
How to Pick a Curbing Contractor for 97338
A few things to check before you sign a curbing quote in Dallas:
- Oregon CCB license -- legally required for any contractor working in Oregon. Verify it before the deposit.
- General liability insurance -- a curb machine throws aggregate; a job site with people or vehicles nearby needs documented coverage.
- Mix design specified -- the quote should list the mix (typically 3,000 to 4,000 PSI for curbing) and the air entrainment percent. If it doesn't, ask.
- Joint plan -- control joints are not optional in Oregon. Quote should show joint spacing.
- Warranty -- 1 year minimum on workmanship, with a clear definition of what counts as failure.
