Cojo installs speed bumps across Corvallis, Oregon — parking lots, private community roads, and OSU-adjacent commercial sites across Benton County. Anything touching public right-of-way runs through the Corvallis Land Development Code (LDC) and Corvallis Public Works for traffic-calming coordination. Private parking-lot installs don't need a city permit, but ADA-accessible routes (ADA Title III) and fire-apparatus access (IFC Section 503) still apply.
Below: Corvallis permit setup, the neighborhoods we cover, two real installs, and how to request a quote.
What does Corvallis require for a speed-bump install?
Three layers, depending on where the bump is going:
1. Private parking lots: no city permit required
A speed bump installed entirely on private parking-lot property in Corvallis does not require a city permit. Cojo verifies that the install preserves ADA-accessible routes, fire-apparatus access per Corvallis Fire Department, and adjacent stormwater facilities subject to Corvallis's stormwater management code.
2. Public right-of-way: Corvallis LDC and Public Works review
Corvallis public-street speed humps follow Corvallis Public Works' traffic-calming process. The Corvallis LDC governs land-use and right-of-way improvements; private parking-lot speed bumps fall outside the LDC's primary scope.
3. Oregon State University properties: campus facilities approval
OSU properties are state-owned and follow OSU Capital Planning and Development standards rather than city standards. Cojo coordinates campus installs through OSU facilities. OSU campus-shuttle and emergency-vehicle considerations typically drive the installs toward lower-profile (2.5 to 3-inch) bumps.

Two real Cojo Corvallis installs
Install 1: Timberhill retail center, July 2025
A 12,000-square-foot retail center on NW Highland. The leasing manager had documented over-speed customer traffic and one cart-vehicle near-miss. Cojo installed three 8-foot rubber bumps, 3 inches tall, with chevron and reflective tape, plus MUTCD W17-1 advance signage. Total install: 5 crew-hours on a Sunday morning.
Install 2: Corvallis School District elementary, March 2026
An elementary school in the Corvallis School District. The parent-drop-off lane had documented over-speed concerns from the crossing-guard supervisor. Cojo installed three rubber bumps, two with 36-inch ADA gaps. Coordinated with district facilities and scheduled during a school break. Detailed approach in speed bumps for school zones.
What does it cost to install speed bumps in Corvallis?

Current Market Reality
2026 Corvallis install pricing reflects mobilization travel time from the Salem operations base, Oregon prevailing-wage requirements on commercial sites above $25,000, and elevated rubber-feedstock costs. Corvallis installs typically batch with Albany or Eugene projects for crew-mobilization efficiency.
