Portland's parking lots run a wider mix of conditions than almost any other Oregon market: tight downtown footprints, sprawling east-side retail strips, drive-thru queues at every quadrant, and freeze-thaw cycles that compound polymer wear. Cojo installs delineators across the metro and tunes the spec to the lot rather than the other way around.
The 60-word direct answer: Cojo installs delineators on Portland parking lots, drive-thrus, and pickup zones per MUTCD Section 3F.04 color rules and Title 33 land-use coordination. Standard spec is engineered urethane flex posts on spring bases with Type IV retroreflective sheeting. Typical project sizes run 8 to 50 stations. Service area covers Portland, Beaverton, Hillsboro, Gresham, and Lake Oswego.
Three Portland-specific factors shape the delineator spec on most metro projects.
Two layers stack.
Color rules per MUTCD Section 3F.04 (white on right, yellow on left, blue at hydrants). Sheeting type per ASTM D4956. Crash-test compliance per NCHRP 350 or MASH for any post adjacent to a public street.
Portland's Title 33 zoning code regulates land use, including parking-lot striping and channelization for accessibility-route compliance. Most delineator work doesn't trigger Title 33 directly because it's not a structural change, but tenant-improvement and full-site reconfiguration projects route through Title 33 review where ADA accessibility-route channelization is part of the scope. For ADA-route specifics, see ADA parking requirements Oregon.
| Spec | Portland Default |
|---|---|
| Post height | 36 inch standard, 48 inch on entry-apex strikes |
| Polymer | Engineered urethane (1,000-plus cycle, low-temp derate) |
| Base | Spring base on plowed lots, in-ground sleeve on removable applications |
| Sheeting | Type IV high-intensity prismatic |
| Color | MUTCD per Section 3F.04 |
| Spacing | 8 to 12 ft on drive-thru queues, 30 to 50 ft on counter-flow centerlines |
| Anchor | Surface-mount with stainless mechanical anchors |

Cojo channelized a 38,000-square-foot Northeast Sandy Boulevard QSR drive-thru in February 2026. The lot had no entry-apex commitment and a chronic strike rate of 8 to 12 events per week on the original delineators. Cojo installed 14 engineered urethane flex posts on spring bases at 8-foot spacing along the 110-foot queue, plus 4 white posts at the queue exit. Strike rate post-install dropped to 3 to 5 per week, all of which recovered without replacement.
A 22,000-square-foot retail strip on Outer Southeast 82nd Avenue had a chronic centerline drift problem in the main drive aisle. Cojo installed 18 federal yellow flex posts on spring bases at 40-foot spacing along the 700-foot centerline. The 60-day post-install walk showed measurable lane commitment and no centerline conflict events.
A 14,000-square-foot mixed-use ground-floor lot in the Pearl District needed delineator channelization at three pedestrian-crossing approaches. Cojo installed 12 federal yellow flex posts on spring bases at the corner radii. The MUTCD-compliant placement met Title 33 accessibility-route review on first submission.
Industry Baseline Range
| Scope | Cost |
|---|---|
| Single-station replacement (post and base) | $80 to $180 |
| Drive-thru queue (50 to 100 ft, 8 to 14 stations) | $700 to $2,500 |
| Counter-flow channelization (per 100 ft) | $400 to $1,400 |
| Mobilization and traffic control (per visit, Portland metro) | $400 to $1,800 |
Through 2026, Portland traffic-control labor has tightened with new permit requirements on city right-of-way work, which has pushed mobilization costs toward the upper end of the published range. Bundled installs across multiple lots in a regional account stretch mobilization across more sites and bring the per-site cost down.
