Speed table installs in Portland run through the Portland Bureau of Transportation (PBOT) Neighborhood Greenways and Traffic Calming program. On bus-route corridors we coordinate with TriMet; in historic districts where brick-inlay tables integrate with the streetscape, design review gets involved. PBOT has installed tables on Vision Zero priority corridors and on greenways that overlap with TriMet service. We handle design coordination and installation across the Portland metro. Below: how the local approval process works, plus the service-area context.
Portland's approval process for speed tables on residential streets runs through PBOT's traffic-calming program:
Timeline runs 6 to 24 months from petition to install. Vision Zero priority corridors run shorter; bus-route or historic-district installs run longer because of the additional coordination.
The current PBOT program documentation is published on the PBOT Vision Zero and Neighborhood Greenways pages. Always verify current program eligibility, funding levels, and waitlist with PBOT before assuming a particular cost-share rate.
Portland Title 17 (Public Works) governs work in the public right-of-way. Title 33 (Planning and Zoning) governs site design including private street tables. Relevant references:
Always verify current requirements with the issuing jurisdiction. This article reflects May 2026 published guidance.
Portland's listed historic districts and design-review-overlay zones often require visual integration with surrounding streetscape, which makes brick-inlay or paver-inlay speed tables a natural fit. Areas where Cojo has worked or coordinated brick-inlay tables include:
Brick-inlay tables typically cost 50 to 90% more than standard asphalt tables, so they are reserved for streets where design review specifically requires visual integration. PBOT and the Portland Historic Landmarks Commission jointly review proposals.
Cojo is a Portland-area asphalt and traffic-calming contractor with experience on PBOT projects. We coordinate the city traffic-calming application packet, field survey, paving, traffic control, and pavement marking in one scope. We form standard parabolic, sinusoidal, and brick-inlay speed tables; the brick-inlay configuration involves a separate hardscape crew that lays paver inlay over the asphalt structural slab.
For bus-route projects we coordinate with TriMet during design review on table location relative to bus stops and on profile selection (sinusoidal preferred on primary routes). For historic-district projects we coordinate with the Portland Historic Landmarks Commission on paver selection, edge detail, and pattern alignment.
A Inner Southeast neighborhood association coordinated with PBOT on a 5-table install along an east-west greenway corridor. The corridor included a TriMet bus stop and a school crossing. PBOT specified standard parabolic asphalt tables on the segment without bus service and a sinusoidal-profile table at the bus stop location. Cojo installed all five tables across two working days, with a separate hardscape day for the crosswalk markings on the school-crossing table.
A residential street in the Northwest Portland Historic District required design review for any traffic-calming installation. Cojo and the neighborhood coordinated with the Portland Historic Landmarks Commission on a brick-inlay configuration that matched adjacent paver patterns at intersections. The 22-foot tables were installed with asphalt structural slabs and 16-foot brick inlay on the flat-top sections; ramps remained asphalt to allow standard maintenance practices.
A hospital campus on Portland's westside required traffic calming on internal access drives that doubled as service-vehicle and patient-transport corridors. Cojo installed three concrete cast-in-place speed tables sized for the hospital's heavy commercial fleet. Concrete was selected because internal hospital service roads see significant truck traffic that asphalt installs would not survive at the same lifecycle cost.

Where a speed table is proposed on a TriMet bus route, PBOT coordinates with TriMet planning during design review. Two coordination items are typical:
For transit-corridor specifications see speed tables on bus routes.
PBOT funds qualifying speed table installations through the Neighborhood Greenways program. Cost-share commonly covers 50 to 100% of installation cost on Vision Zero priority corridors. Brick-inlay configurations typically receive partial cost-share with the historic-district premium funded by the property owner or HOA. Always verify current program funding and eligibility with PBOT.
For private campus drives (commercial, hospital, hotel, university), PBOT cost-share does not apply; the property owner funds the install directly.
