We install speed bumps statewide across Oregon — Portland metro, the south coast, the Willamette Valley, Central and Eastern Oregon. Authority for these jobs is layered: ODOT covers state highways, county road departments cover county roads, and city public-works departments cover city streets. Private parking lots don't need a permit at any level, but ADA-accessible routes (ADA Title III) and fire-apparatus access (IFC Section 503) still apply everywhere.
What's below: the Oregon-wide regulatory picture, our statewide service-area map, how pricing varies, and links to every city service page we run.
Who has authority over speed bumps in Oregon?
The authority depends on which road the bump sits on:
1. State highways: ODOT
Oregon Department of Transportation has authority over Oregon's state-highway system, including I-5, I-84, US-26, US-101, and the OR state-route network. ODOT does not install speed bumps or speed humps on state highways; the ODOT Traffic Manual instead specifies engineered alternatives (rumble strips, signal timing, signage) for state-highway speed control.
2. County roads: county public-works department
County roads -- the rural connector network outside city limits -- are governed by each county's public-works department. Most Oregon counties (Marion, Lane, Linn, Benton, Douglas, Jackson, Deschutes, Washington, Clackamas, Multnomah) have residential-traffic-calming programs administered by the county road department. County roads commonly use speed humps (12 to 14 ft long) instead of speed bumps.
3. City streets: city public-works department
City streets are governed by each city's public-works department. Public-street speed humps follow each city's traffic-calming process. See city-specific service pages below.
4. Private property: property owner directs the install
Speed bumps installed entirely on private parking-lot property -- past the right-of-way line -- do not require a permit at any level of government. The property owner or manager directs the installation. The Oregon Revised Statute ORS 811.555 governs obstructions on public ways but does not apply to bumps installed entirely on private property.
What does ORS 811.555 say about parking on speed bumps?
ORS 811.555 governs stopping or parking in places where prohibited. Subsection (1)(c) makes it unlawful for a driver to stop, stand, or park a vehicle in a manner that "blocks or otherwise obstructs traffic on a roadway." Parking on a speed bump that blocks a drive aisle qualifies. The fine for a typical violation is in the Class C traffic-violation range.
ORS 811.555 does not regulate the installation of speed bumps -- only the conduct of drivers around them. For the installation rules, see ITE and FHWA standards cross-referenced on Cojo's speed bump standards page.

Current Market Reality
2026 Oregon install pricing varies meaningfully by tier. Tier 1 cities (Portland metro, Salem, Eugene-Springfield) carry the most competitive pricing because Cojo crews mobilize there frequently. Tier 2 and Tier 3 markets carry travel premiums of $300 to $1,500 per mobilization, partially offset by batch-scheduling with other regional projects. Oregon prevailing-wage requirements apply to commercial sites above $25,000 in scope across all tiers.
