Concrete curbing in 97634 covers Midland and the south Klamath Basin ag-commercial corridor between Klamath Falls and Merrill. The 97634 zip is potato, onion, and hay country with a small commercial footprint -- the warehouse and packing-shed corridor along Hwy-39, a few outlying ranch headquarters, and the parcels that abut the Lower Klamath National Wildlife Refuge. Cojo dispatches Klamath South concrete routes from Hood River, bundling Midland with Merrill, Bonanza, Dairy, and the Klamath Falls metro work to make the trip pencil. The work pattern is functional rather than decorative -- structural curb-and-gutter, drainage channels, and ag-yard perimeter curbing.
What 97634 Curbing Jobs Look Like
The 97634 curbing buyer base is ag-commercial and rural-functional. Warehouse-yard perimeter curbing that defines a truck route and keeps gravel off Hwy-39. Drainage curb-and-channel cuts on packing-shed lots where stormwater compliance matters. Ranch-headquarters drives that need a grade-control edge. The occasional small downtown lot perimeter where curb-and-gutter is part of a parking-lot rebuild. We see very little landscape-edging curbing here -- the residential density does not support it and the agricultural buyer base wants curb that does structural work.
Standard scope reads like this. Extruded ag-yard curb runs 6 to 12 inches tall by 6 to 12 inches wide. Structural curb-and-gutter is form-poured 12 to 18 inches on the gutter pan and 6 inches at the curb face. Drainage channel and curb is typically a custom-form pour with sloped channel and integrated curb. We spec air-entrained 4,500 PSI mix on every Klamath South job because of the freeze-thaw load -- and on ag-warehouse jobs we bump to 5,000 PSI where the curb has to take regular truck impact.
Dry-Pour Climate and Refuge-Adjacent Drainage
Midland sits at about 4,100 feet of elevation. Summer pour conditions in 97634 are dry-pour conditions -- ambient regularly above 90 degrees F, single-digit humidity, water flashing out of the mix faster than cement can hydrate. We pour 97634 jobs in early morning hours during May, June, and September. July and August midday work is scheduled around mix-water temperature, evaporation retarder, and shaded curing. Winter pours are off the table from late October through mid-April.
The Lower Klamath National Wildlife Refuge sits along the south edge of 97634. Work on parcels adjacent to the refuge has wetland-setback considerations through the US Fish and Wildlife Service and Klamath County, and stormwater rules for new impervious surface or drainage modification are stricter near refuge boundaries. We pull the setback and refuge-coordination letters as part of permitting on any 97634 job that touches the south or west edge of the zip. For broader cost context see our concrete curbing cost per foot in 2026 guide.
Cost Picture for 97634 Curbing
Pricing in 97634 follows the same haul-and-bundle pattern as the rest of Klamath South. Ready-mix concrete out of Klamath Falls has real delivery cost, and dispatch from Hood River for a single Midland job adds significant mobilization premium.
Industry Baseline Range
| Project Type | Cost Per Linear Foot | Typical Total |
|---|---|---|
| Extruded ag-yard / equipment-yard curb | $9 to $18 | $800 to $5,500 |
| Structural curb-and-gutter (parking lot) | $25 to $55 | $4,000 to $30,000+ |
| Drainage channel + curb (structural) | $35 to $80 | $4,500 to $32,000+ |
| Warehouse-perimeter heavy-duty curb | $30 to $65 | $5,500 to $40,000+ |
| Mobilization for standalone dispatch | $400 to $1,800 | Per-trip premium |
Current Market Reality
Real 97634 curbing pricing in 2026 tracks above baseline midpoint on standalone work and near or below midpoint on bundled-route work. Ready-mix concrete is up about 18 percent over 2022 because of fuel and cement-plant pass-through. Rebar and form materials are up more. On a bundled Klamath South route, a 97634 ag-yard curb job that prices at $4,200 standalone might run $3,100. We bundle whenever the schedule allows. Emergency repairs where stormwater compliance is on you do not have the luxury -- those we mobilize.
Klamath County Codes and Refuge Setbacks
Most 97634 curbing work pulls Klamath County Public Works review and ODOT Region 4 if the work affects Hwy-39 right-of-way. Refuge-adjacent parcels also pull Klamath County land-use review and, on the wetland-edge parcels, US Fish and Wildlife coordination. Storm-water rules for new impervious over 5,000 square feet trigger DEQ 1200-C construction general permit.
We handle the permit paperwork on every 97634 job. If a contractor is telling you the owner can pull these permits themselves on a commercial scope, that is technically possible and practically a bad idea -- the contractor's license is referenced in the permit application and a homeowner-pulled commercial permit creates liability exposure.

How a 97634 Job Sequences in a Klamath South Route
A Cojo Klamath South dispatch is two to four days running through Midland, Merrill, Dairy, Bonanza, and Klamath Falls. Concrete pours land in early-morning slots when ambient is below 75 degrees F. Cure-time is 72 hours wet-cure for fresh pours in this climate, longer than the 24-to-48 you get away with in Portland weather. A Midland warehouse curb pour staged on day one is ready for backfill and adjacent surface work by day four. Sealcoat or stripe work on the same dispatch slots into days four and five.
For related Klamath-area service coverage, see sealcoating across Klamath County and Klamath County striping work. The concrete scope rolls through our concrete services page.
