Parking Lot Curbing Installation in Beaverton, Oregon

Parking lot curbing in Beaverton, Oregon, runs through Beaverton Code Title 6 (Public Works Construction), Engineering Design Standards, and ADA Accessibility Guidelines for any ramp tying into the public sidewalk. The Cedar Hills Crossing area, Beaverton-Hillsdale Highway corridor, and Murray Boulevard commercial frontages account for most of the city's commercial parking-lot curb scope.

What follows: how our crews scope, permit, pour, and inspect parking lot curbing in Beaverton — including the Washington County stormwater coordination that retrofits routinely trigger.

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

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

What permit applies in Beaverton?

• Inside private parking lot: Beaverton building permit covers the curb work as part of site civil scope.
• Right-of-way work: Beaverton Public Works Permit. Review takes 4 to 8 weeks (Beaverton's review queue runs longer than smaller cities).
• Stormwater changes: Beaverton's Engineering Design Manual triggers a stormwater review when curb-and-gutter retrofit changes flow into the city or Clean Water Services (CWS) regional system.

What concrete mix does Beaverton require?

Beaverton Engineering Design Standards reference ODOT 00759:

Spec	Beaverton / 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
Surface tolerance	1/4 inch over 10 feet
Subgrade compaction	95% standard Proctor
Base aggregate	4 inches compacted under curb line

Beaverton-area concrete supply runs through Knife River, CalPortland, and Glacier Northwest. The mix-design ticket gets reviewed before pour and the inspector verifies on first delivery.

A recent Beaverton install of ours

In July 2025 our crews installed 1,540 linear feet of new 6-inch barrier curb plus six ADA curb ramps at a 42,000-square-foot retail center near Cedar Hills Crossing. The original site had 1980s curb that had failed at every freeze-thaw joint after three decades. We saw-cut and demoed in 12-foot sections, coordinated with Clean Water Services on the existing stormwater outfall, reset #4 longitudinal rebar, and slipformed Class 4000 perimeter curb at 165 linear feet per day. Beaverton Public Works inspector signed off on day 14. The project added cast-in-place truncated dome panels at all six ADA ramps, including two at the front entrance crossing.

How much does parking lot curbing cost in Beaverton?

Industry Baseline Range

Curb Type	Price Per Linear Foot (Installed)
6-inch barrier curb (slipformed)	$12 to $22+
Mountable curb (4-inch face)	$10 to $18+
Curb and gutter (combined section)	$18 to $32+
ADA curb ramp (each, with truncated domes)	$1,400 to $3,800+
Hand-formed irregular radius	$20 to $40+

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

Beaverton tracks Portland metro pricing because of shared batch plants and similar commercial labor markets. Demolition adds $6 to $14 per linear foot. Washington County permit fees add 3 to 8 percent to the total project cost on right-of-way work. See our broader parking lot curbing cost breakdown.

Why does Beaverton require Clean Water Services coordination?

Beaverton sits inside the Clean Water Services (CWS) service area, which manages the regional stormwater and wastewater system across Washington County. When a curb-and-gutter retrofit changes how a commercial lot grades into the public stormwater system, both Beaverton Engineering and CWS review the design. Three implications:

1. Two-step review. Beaverton issues the construction permit; CWS reviews the stormwater design. Both have to sign off before mobilization.
2. Retrofit BMP triggers. Older lots without stormwater best management practices (BMPs) frequently have to add a CWS-approved BMP (vegetated filter strip, infiltration trench, water quality manhole) when curb work changes the runoff pattern.
3. Design standards harmonization. CWS Design and Construction Standards take precedence over Beaverton standards on stormwater elements. We design to the stricter of the two on every job.

What about ADA curb ramps in Beaverton?

Beaverton ADA Transition Plan applies the 1:12 max running slope rule, 36-inch min width, 4-foot top landing, and detectable warning surface (truncated domes) per ADAAG 4.7. Cast-in-place truncated dome panels are our default on every new pour. See ADA curb ramp slope requirements for the full walk-through.
