Concrete curbing in 97009 covers Boring -- the small rural-residential community at the Highway 26 and Highway 212 junction, plus the surrounding subdivision growth that has filled in over the last 15 years. This ZIP straddles the Multnomah-Clackamas county line, which affects permitting on parcels near the boundary. The curb work here is mostly rural subdivision build-out, small commercial frontage along the Highway 212 corridor, and drainage-driven residential curbing where steep-grade lots are being developed.
What 97009 Curb Work Typically Looks Like
The defining feature of Boring curb work is the project scale. Most jobs here run smaller than central-Portland commercial work but more complex than a flat-ground suburban lot. Three patterns repeat across the ZIP:
- New-subdivision perimeter curbing along internal streets that haven't been dedicated to the county yet -- developer scope before final acceptance.
- Driveway and frontage curbing for individual residential lots upgrading from gravel to paved drives.
- Highway 212 commercial frontage curbing for small businesses, country stores, and the handful of light-industrial pads near the junction.
- Drainage channelization curbs (valley gutter, ribbon curb) on parcels with steep grade or runoff issues.
The Highway 212 corridor also has periodic ODOT-adjacent work where private curb meets state right-of-way. Those projects need a coordination step with ODOT Region 1 before the pour.
Extruded vs. Formed Curb in 97009
We install both, and each has its place. Extruded curb (machine-run) is faster and cheaper per linear foot. It works well on long straight runs and gentle curves -- which is most subdivision perimeter scope. Formed curb (poured in place against wood or steel forms) is required for tight radii, ADA curb ramps, transitions to existing concrete, and any application where the curb height varies along its length. Most 97009 jobs use a mix: extruded on the long runs, formed on the corners and the ADA ramps.

Cost Discipline: What 97009 Curbing Runs
Curb pricing scales with linear footage, curb type, ADA scope, and access. Boring sites are typically rural with good truck access, which means access doesn't usually inflate the cost the way it does in central Portland. But the rural location adds ready-mix delivery distance from the nearest batch plant, and small-pour minimum charges sometimes apply when the linear footage is short.
Industry Baseline Range
| Scope | Per Linear Foot | Typical Project Total |
|---|---|---|
| Extruded curb, standard 6-inch | $9 to $18 | $1,200 to $8,000+ |
| Formed curb, standard 6-inch | $14 to $32 | $2,000 to $20,000+ |
| ADA curb ramp (per ramp, includes truncated domes) | — | $1,800 to $5,500+ |
| Valley gutter or ribbon curb (drainage) | $18 to $40 | $3,000 to $25,000+ |
| Small-pour ready-mix minimum (when under threshold yardage) | — | $250 to $600+ |
Current Market Reality
Concrete material costs have run 18% to 25% above 2021 baseline since 2024 because of Portland-cement supply tightness and fuel cost on ready-mix delivery. The rural location adds delivery distance from the Damascus or Sandy batch plants, which can push small-pour jobs over the minimum-yardage threshold and trigger an additional charge. Clackamas County crew rates have climbed with regional construction demand. A small 97009 curb job that was $3,500 in 2019 is closer to $5,000 to $6,000 today for the same scope.

Clackamas County and Multnomah County Edge Cases
97009 spans both counties. Most of the ZIP sits in Clackamas County, but a small northern portion crosses into Multnomah County near the Highway 26 corridor. Permit jurisdiction depends on parcel location, and the two counties have slightly different requirements for:
- Driveway connection permits to county roads.
- Stormwater management thresholds for new impervious surface.
- ADA curb ramp standards on parcels adjacent to county right-of-way.
For parcels near the county line, we confirm jurisdiction on the walk and pull permits with the correct agency. Property owners do not have to navigate the dual-jurisdiction question themselves.
Drainage and Why Curb Type Matters
Many 97009 parcels grade enough to need channelized drainage rather than just defined edge. The two failure modes we see most often on rural Boring curb work:
- Edge curb on a downhill driveway that undercuts within 5 to 10 years because runoff washed out the base behind the curb. Fix: use ribbon or valley gutter instead of standard edge curb, or include a uphill swale.
- ADA ramp cross-slope drift caused by ground settle. Fix: pour the ramp on stabilized subbase with proper compaction.
Both failures are install-time problems, not maintenance problems. The curb has to be built right the first time or the warranty pays for the repair, not the original install.
ADA Compliance on Commercial 97009 Work
Most rural-residential curb work in 97009 has no ADA scope. But commercial pad work along Highway 212 and any new-subdivision public-frontage work does. Oregon's 2026 ADA rules require curb ramps where accessible routes cross any curb, with slope tolerance of 1:12 maximum running and 1:48 cross-slope. We measure with a digital level before every ADA pour. If the existing grade is too steep for a code-compliant ramp without regrading, we map the regrading scope and quote it separately.
Bundling Curb With Other Lot Work
Curb work in 97009 frequently pairs with new asphalt -- either as part of a driveway install or as part of a new-subdivision build-out. The right sequence is: demo old surface, regrade and rebuild base, pour curb and ADA ramps, pave new asphalt up to the curb face, sealcoat after cure, stripe last. Doing curb standalone makes sense when the surrounding asphalt is sound; doing it as part of a full sequence makes sense when the lot or driveway needs broader work.
For new-asphalt work that follows curb installation, our concrete curb installation in Portland page describes the install process in detail. Once asphalt is cured, Clackamas County sealcoating cycle keeps it on schedule.
How a 97009 Curb Quote Comes Together
We walk the site, measure linear footage, identify ADA scope, note grade and drainage constraints, confirm county jurisdiction at the parcel level, and identify access for ready-mix delivery. The written quote itemizes curb type, ADA ramps, drainage features, county permit cost, and any access add-ons. Most quotes turn around inside 48 to 72 hours.
