Cojo installs speed bumps across Gresham, Oregon — parking lots, private community roads, and commercial sites throughout east Multnomah County. If your install touches public right-of-way, Gresham Revised Code (GRC) Article 7 (Streets and Sidewalks) is the governing code plus Gresham Public Works for traffic-calming coordination. Private parking lots skip the permit, but ADA-accessible routes (ADA Title III) and fire-apparatus access (IFC Section 503) still need to stay clear.
Below: Gresham's permit setup, the neighborhoods we run, three real installs, and how to request a quote.
What does Gresham 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 Gresham does not require a city permit. Cojo verifies that the install preserves ADA-accessible routes, fire-apparatus access per Gresham Fire & Emergency Services, and adjacent stormwater facilities subject to Gresham's stormwater management code.
2. Public right-of-way: GRC Article 7 and Public Works review
Gresham public-street speed humps follow Gresham Public Works' traffic-calming program. Citizens initiate requests through the Public Works neighborhood-services contact. Engineering review and city budget cycle govern the timeline.
3. Gresham Fire & Emergency Services: fire-access coordination
Gresham Fire & Emergency Services maintains designated fire-apparatus access roads. Speed bumps on those roads require fire-marshal coordination, with the typical resolution being a speed cushion (with wheel-track gaps for ladder trucks) instead of a solid bump.

Three real Cojo Gresham installs
Install 1: Rockwood multifamily property, May 2025
A 96-unit apartment complex in the Rockwood area. The property had received an insurance-renewal request for engineered traffic-calming and tenants had submitted complaints about over-speed traffic on the main drive aisle. Cojo installed three 8-foot rubber bumps after a 7-day ORS 90.322 tenant notice. Detailed approach in speed bumps for apartment complexes.
Install 2: Pleasant Valley retail center, October 2025
A 16,000-square-foot retail center along Foster Road. The leasing manager had documented over-speed customer traffic and pedestrian-crossing complaints from anchor-tenant managers. Cojo installed three 8-foot rubber bumps with chevron, reflective tape, and MUTCD W17-1 signage. Total install: 6 crew-hours.
Install 3: Centennial mixed-use development, February 2026
A small-format mixed-use development in the Centennial area with retail on the ground floor and apartments above. The combined retail-and-resident traffic produced over-speed events at the main drive aisle. Cojo installed two rubber bumps with retail-spec markings, plus building-mounted "Bump" signage to maintain visibility through the building shadow zones.

Current Market Reality
2026 Gresham install pricing reflects Oregon prevailing-wage requirements on commercial sites above $25,000 in scope, elevated rubber-feedstock costs, and added documentation expectations from Multnomah County and Gresham-area property-insurance underwriters. Gresham installs are typically scheduled with other Portland-east projects to amortize crew-mobilization costs.
