Do I need a Salem permit for curbing inside my private parking lot?

Curb that stays inside private property typically falls under the Salem building permit covering the broader site work. A separate Salem Public Works permit applies when the curb ties into the public right-of-way -- driveway aprons, curb cuts, sidewalk corners, or work that changes how the lot grades into the city stormwater system. We pull the right permit at the site walk.

What concrete mix does Salem require for a parking lot curb?

Salem follows ODOT Standard Specification 00759: Class 4000 concrete (4,000 PSI minimum at 28 days), 5 to 7 percent air entrainment, water-cement ratio at or under 0.45, slipform slump at 1 to 2 inches. The mix-design ticket from the supplier gets reviewed before the pour, and the inspector witnesses slump and air-content tests on the first truck delivery.

How long does our Salem permit-to-pour timeline run?

Public Works permit review runs 4 to 6 weeks for a standard parking lot curb application. After permit issuance, the field schedule is roughly 1 to 2 days subgrade prep, half a day to set forms or stage the slipform machine, 1 to 2 days to pour, and a 7-day minimum cure before traffic. Most parking lot curb projects finish within 3 weeks of permit-in-hand.

Does Salem have a curb-cut or driveway apron permit fee?

Yes -- Salem Public Works charges a permit fee plus a per-linear-foot inspection fee for any work in the right-of-way. The exact dollar figures change annually -- we pull the current fee schedule when we scope your job. Budget 3 to 8 percent of the construction cost for permit and inspection fees in the right-of-way scope.

How does Salem handle ADA curb ramps on private commercial property?

Inside a private lot, ADA curb ramps follow ADAAG 4.7 (1:12 max slope, 36-inch min width, detectable warning surface, 4-foot top landing) and trigger ADA enforcement under federal civil-rights law. When a private redevelopment touches the adjacent right-of-way corner, Salem requires the corner ramp to be brought up to current standards as part of the Salem ADA Transition Plan -- this is often the first surprise on an older parking-lot retrofit.

Parking Lot Curbing Installation in Salem, Oregon

A parking lot curb in Salem, Oregon, lives at the intersection of three rule sets: Salem Revised Code Chapter 79 (right-of-way and street construction), the Salem Public Works Construction Specifications (mix design, jointing, surface tolerance), and the ADA Accessibility Guidelines for any ramp tying the lot into the public sidewalk. We work all three on every Salem parking-lot curb scope.

What follows is the practical version of how our crews scope, permit, pour, and inspect parking lot curbing in Salem — including what the Willamette Valley freeze-thaw cycle does to under-spec concrete after 8 years.

What is the right curb spec for a Salem parking lot?

Direct answer: A standard Salem parking lot curb is 6 inches tall, 6 to 8 inches wide at the base, poured in Class 4000 concrete with 5 to 7 percent air entrainment per Salem Public Works Construction Specifications and ODOT 00759. Expansion joints sit every 10 to 15 linear feet, control joints every 10 feet, and ADA curb ramps follow the 1:12 maximum slope rule. Cojo crews slipform 100 to 200 linear feet per day on commercial lots in Salem.

What permit do I need for parking lot curbing in Salem?

It depends on whether the curb touches the public right-of-way:

Inside a private parking lot: Salem Building Permit (site permit) covers the curb work as part of the paving scope. No separate Public Works permit unless the lot grades flow into the city stormwater system in a new way.
Driveway apron, curb cut, or sidewalk corner: Salem Public Works Permit under Salem Revised Code Chapter 79 is required. Review takes 4 to 6 weeks for a standard commercial application.
ADA curb ramp at a public crossing: Falls under both Salem Public Works and the city's ADA Transition Plan. Salem has run a multi-year program upgrading downtown corner ramps -- private redevelopment is often required to upgrade adjacent right-of-way ramps to current standards.

What concrete mix does Salem require?

Salem follows ODOT Standard Specification 00759 and the Salem Public Works Construction Specifications for any right-of-way pour. The headline numbers:

Spec	Salem / ODOT 00759
Compressive strength	Class 4000 (4,000 PSI at 28 days)
Air entrainment	5% to 7%
Maximum water-cement ratio	0.45
Slump (slipform)	1 to 2 inches
Slump (hand-form)	3 to 5 inches
Surface tolerance	1/4 inch over 10 feet

We submit a mix-design ticket from our concrete supplier (CalPortland or Knife River are the most common Salem-area sources) before the pour and the inspector verifies on delivery.

What does the Salem inspection sequence look like?

Subgrade inspection

The inspector verifies 95 percent compaction (ASTM D698 standard Proctor) on the prepared subgrade and 4 inches of compacted aggregate base under the curb line. Soft spots get re-rolled or over-excavated and recompacted before forms set.

Form and rebar inspection

Slipform machines do not get a pre-pour form check the way hand-formed work does, but the inspector verifies stringline alignment, rebar positioning (#4 continuous in barrier curb), and expansion-joint placement against the approved plan.

Pour-day witness

Salem inspectors witness the first truck delivery to verify slump, air content (air-meter test), and concrete temperature against the mix-design ticket. They walk the cure protocol -- curing compound application or wet-burlap method.

Final inspection

After the 7-day cure, the inspector re-walks for surface tolerance, joint quality, and compliance with the approved drawings. Sign-off triggers the certificate of occupancy on a new build or release of warranty hold-back on a retrofit.

How much does parking lot curbing cost in Salem?

Industry Baseline Range

Curb Type	Price Per Linear Foot (Installed)
6-inch barrier curb (slipformed)	$11 to $20+
Mountable curb (4-inch face)	$9 to $17+
Curb and gutter (combined section)	$17 to $30+
ADA curb ramp (each, with truncated domes)	$1,300 to $3,500+
Hand-formed irregular radius	$18 to $36+

These figures reflect published industry averages. Current market pricing varies significantly and actual quotes may fall well outside these ranges based on site-specific conditions, material costs, and project complexity.

Current Market Reality

Salem-area concrete prices ride 5 to 10 percent below Portland metro because of shorter haul distances from valley batch plants but track the same material-cost climb since 2022. Demolition adds $5 to $12 per linear foot. Smaller jobs (under 200 linear feet) carry a higher per-foot rate because of mobilization. See our broader parking lot curbing cost breakdown for full context.

A recent Salem install of ours

In March 2026 our crews installed 740 linear feet of new 6-inch barrier curb plus four ADA curb ramps at a 14,000-square-foot retail center on Lancaster Drive NE. The original site had a mix of asphalt curb and concrete curb. We removed the asphalt curb fully, retrofitted the surviving concrete sections, and slipformed Class 4000 perimeter curb. Salem Public Works inspector signed off in two visits over 11 days. The retrofit triggered an ADA upgrade on the adjacent right-of-way corner ramp at the Lancaster intersection, which we coordinated separately under a Salem Public Works permit.

What about ADA curb ramp work in downtown Salem?

Downtown Salem is in the middle of a multi-year ADA Transition Plan rollout. Many of our private-lot curb projects now trigger upgrades to the adjacent right-of-way corner ramps. The 1:12 maximum running slope rule, 36-inch minimum width, 4-foot top landing, and detectable warning surface all apply. See ADA curb ramp slope requirements for the full ADAAG 4.7 walk-through.

What curb type fits a Salem retail or HOA lot?

For most Salem commercial parking lots, the default mix is:

6-inch barrier curb on perimeters where pedestrians need clear separation from vehicles
Mountable curb (4-inch face) at fire-lane access points and at drive-aisle radius corners that delivery trucks have to swing through
Ribbon curb in drainage channels where sheet flow runs to a catch basin

How does winter pour weather work in Salem?

Salem winters are wet but rarely hold below freezing for more than a few days at a time. We pour year-round but use heated blankets and tarps when ambient temperature drops below 40 degrees F at pour. Concrete additives (non-chloride accelerators) shorten the early set window. The biggest seasonal risk is rain washing fresh concrete -- we stage tarps and have crews on standby whenever the forecast shows precipitation within 8 hours of a scheduled pour.
