We install speed humps across the Portland metro — Pearl District commercial drives, Lloyd District apartment complexes, Hollywood and Sellwood residential streets. Some jobs run through PBOT's residential traffic-calming program (public streets); the rest we handle directly with HOA boards and property owners (private streets). What's below: the local codes, the neighborhoods we cover, recent project examples, and what 2026 Portland speed-hump pricing actually looks like.
What does it take to install a speed hump in Portland?
For a public Portland street, the PBOT residential traffic-calming program sets the eligibility criteria, conducts the speed and volume study, and runs the resident-petition process. For a private street, an HOA board or property owner authorizes the work directly under Oregon Revised Statutes Chapter 94 (Planned Communities). Cojo handles the install scope -- design, traffic control, paving, marking, and signage -- on either path.
Portland Code and Program References
Three local references govern Portland speed-hump work:
- Portland City Code Title 17 (Public Improvements) -- governs work in the public right-of-way, including pavement modifications
- PBOT Residential Traffic-Calming Program -- the eligibility and approval process for public-street humps
- PBOT Pavement Spec Section 5 -- material and construction standards Cojo's crews build to
For school-zone installs, Portland Public Schools transportation guidance and the Oregon Department of Education school transportation rules add a transportation-director sign-off.

Recent Cojo Speed Hump Projects in Portland
Project 1 -- Lloyd District 220-unit apartment complex (April 2026)
Cojo installed a single 12-foot parabolic asphalt speed hump on the main entry drive of a 220-unit apartment complex in the Lloyd District after property management logged repeated near-miss reports near the leasing-office crosswalk. Pre-install 85th-percentile speeds at the crosswalk averaged 23 mph; 30-day post-install measurement averaged 14 mph. Total elapsed time from initial property-manager call to installed hump was 19 days.
Project 2 -- Sellwood HOA series install (February 2026)
Cojo installed a series of 3 asphalt speed humps on a 1,150-foot HOA-controlled residential street in Sellwood spaced 320 feet apart. The board approved the design after a unanimous vote in their January meeting. Pre-install 85th-percentile speeds were 28 mph; 60 days post-install measured 19 mph -- a 9-mph corridor reduction.
Project 3 -- Multnomah Village school zone (September 2025)
Cojo installed a 12-foot parabolic hump in the parent drop-off loop of an elementary school in Multnomah Village in coordination with Portland Public Schools transportation. The school's principal had logged 30+ near-miss incidents in the prior school year. Spot speeds in the drop-off loop dropped from 16 mph to 7 mph.

Current Market Reality
Portland's 2026 hot-mix prices and traffic-control labor rates push the city above the Oregon statewide average by roughly 8 to 12 percent. PBOT's resident cost-share program for public-street humps mitigates some of the resident-side cost; private-property installs do not have access to that subsidy but also do not pay the program-administration overhead. See the speed hump cost guide for the full pricing breakdown.
When to Choose a Hump vs Cushion in Portland
Portland Fire and Rescue maintains an active interest in residential calming devices because of the response-time impact. PBOT's program will accept either humps or cushions on most residential streets, but for designated fire-response routes the conversation usually pivots to cushions. The speed cushions guide covers the wheel-track design that lets fire trucks straddle.
For non-fire-response residential streets, school zones, and private property, humps remain the default. Cojo recommends the hump-or-cushion decision be made at the proposal stage, not after the city review starts.
Speed Hump Maintenance in Portland
The wet I-5 corridor climate drives most Portland hump degradation. Cojo's maintenance recommendation for Portland sites:
- Quarterly visual walk (paint, edges, hardware, signs)
- Post-winter inspection in March or April for any hump in the Portland climate zone
- Repaint cycle every 18 months for water-based, every 4 years for thermoplastic
- Annual measurement-grade inspection
The speed hump maintenance reference covers the full lifecycle. Cojo offers an annual maintenance contract for Portland HOA and property-management clients that bundles inspections, paint, and crack-fill into a single line item.
