Cojo installs extruded and poured concrete curbing across the 97106 zip -- Banks, Oregon, the small Washington County town at the junction of Highway 47 and the Sunset Highway. The local work is mostly small-scale: downtown sidewalk-and-curb tie-ins, ag-equipment loading-zone curbs, and residential drainage curbing for the newer subdivision build-out on the south and east sides of town. Pricing depends on linear footage, curb profile, and access, but most local jobs land within the published baseline range below.
Concrete Curbing in Banks -- The Local Picture
Banks is small -- under 2,000 people in the city limits -- but its location at the Highway 47 and US-26 junction makes it a meaningful commercial node for the surrounding ag and timber economy. The town's curbing market has three distinct subtypes:
Downtown sidewalk and curb tie-ins. Older Main Street and surrounding grid streets with curbs dating to the mid-20th century. Most existing curb is in repair-and-replace territory, with periodic ADA cut additions and gutter-pan replacements.
Ag-equipment and small commercial. Feed and seed stores, equipment dealers, and small service businesses with utilitarian lots that need loading-zone curbs, parking-perimeter curbs, and ADA stall delineation.
Newer residential subdivisions. South and east edges of town have seen subdivision build-out over the last 15 years. New-construction extruded curb work for subdivision streets, plus residential drainage curbing for individual lots.
Washington County stormwater code and the city of Banks development standards both apply. Subdivision curbing requires approved drainage plans. Commercial parking-lot curbing typically gets bundled with paving and striping work in a single permit. Residential drainage curbing on private lots usually stays below the permit line.
Curb Types We Install in 97106
The four most common Banks curb types:
- Extruded curb (machine-formed) -- the standard for subdivision streets and parking-lot perimeters. Fast, consistent, and cost-effective on runs over 100 feet.
- Poured curb and gutter -- used for sidewalk tie-ins, ADA ramp transitions, and complex shapes the curb machine can't form.
- Mountable rolled curb -- common in subdivisions where residents drive across the curb to a driveway. Lower profile, gentler slope.
- Heavy-duty loading-zone curb -- thicker profile, reinforced section. Used at ag-equipment loading zones and truck-traffic parking entries.
The right type depends on what the curb has to do. Sidewalk tie-ins require poured work. Subdivision streets work best with extruded. Loading zones need the heavier section. We spec during the on-site walkthrough.

Current Market Reality
The published ranges assume reasonable access for a curb machine, a clean site, and a single mobilization. Banks is about 25 miles from our Hood River HQ but on the Washington County contractor circuit, so mobilization is folded into a multi-job route when possible. Standalone small residential jobs carry proportional mobilization cost; pairing with neighbors or coordinating with paving and striping work usually keeps the per-foot cost reasonable. Concrete mix prices have moved sharply over the last two years; quotes older than 30 days should be re-validated.
Freeze-Thaw and Banks Subgrade
Banks sits at about 250 feet elevation with the typical Tualatin Valley freeze-thaw profile -- 30 to 45 cycles per year on the valley floor. That's enough to drive measurable curb deterioration without proper mix design and joint spacing.
Three mitigations matter:
- Air-entrained concrete mix -- 5 to 7 percent entrained air to absorb ice expansion.
- Subgrade compaction -- a curb on uncompacted base settles, cracks at settlement, and lets water in.
- Control joints every 10 feet -- extruded curb without joints cracks at random; control joints set the failure location.
Banks subgrade is mostly Aloha silt loam over a clay subsoil -- the standard Tualatin Valley profile. The clay holds water in the wet season, which means subdivision drainage curbs along the new-build edges of town carry real stormwater volume. Sizing the gutter pan to match the actual rain-event flow matters.

When Curbing Pairs Well with Other Work
A curbing job in Banks often makes more sense as part of a coordinated scope rather than standalone. Three common combinations:
Curb plus parking-lot paving. New commercial paving with new perimeter curb in one mobilization saves significant cost versus separate jobs. The base prep, equipment mobilization, and disposal logistics all share resources.
Curb plus sealcoat and re-stripe. On existing lots, replacing failing perimeter curb in conjunction with sealcoat and re-stripe gives the lot a complete refresh in one season. Often the most cost-effective path for property managers planning the next maintenance cycle.
Curb plus drainage retrofit. On older subdivision streets where the curb is failing and drainage is marginal, replacing both at once allows us to spec the new curb to actually handle the runoff the original system couldn't. Standalone curb replacement that doesn't fix the underlying drainage problem fails again within a decade.
If your scope might span multiple categories, we walk the site and quote against the combined work to capture the savings. Standalone curb work is fine when that's the right scope; pairing is better when it isn't.
Picking a Curbing Contractor for 97106
What to verify:
- Oregon CCB license -- required, easy to verify.
- Mix design -- PSI (typically 3,000 to 4,000) and air entrainment percent.
- Joint plan -- control joint spacing should appear on the quote.
- Drainage spec -- for any subdivision or new-construction work, the gutter pan and back-angle should match site grade.
- Mobilization plan -- ask if the job can be route-coordinated with adjacent Washington County work.
- Insurance -- general liability and workers' comp.
