We install speed humps across Corvallis — OSU campus-edge residential streets, Timberhill HOA neighborhoods, Corvallis School District drop-off loops. Some jobs work inside the city's transportation system plan; the rest we run directly with HOA boards and property owners. What's below: Corvallis's code, the neighborhoods we cover, recent projects, and 2026 pricing.
What does it take to install a speed hump in Corvallis?
For a public Corvallis street, the Corvallis Land Development Code and the City of Corvallis Transportation System Plan set the framework, and the city's traffic-calming process governs eligibility. For a private street, the HOA board or property owner authorizes the work directly under Oregon Revised Statutes Chapter 94.
Corvallis Code and Program References

Recent Cojo Speed Hump Projects in Corvallis
Project 1 -- OSU campus-edge residential install (April 2026)
Cojo installed a 12-foot parabolic asphalt speed hump on a residential street fronting an OSU-adjacent neighborhood after coordinating with the city's traffic engineering office and the neighborhood association. Pre-install 85th-percentile speeds were 28 mph against a 25-mph posted limit. The 60-day post-install measurement averaged 19 mph.
Project 2 -- Timberhill HOA install (August 2025)
Cojo installed a single 12-foot asphalt hump on a private street in Timberhill after an HOA board vote following two near-miss incidents at a mailbox cluster. The board approved the design at their July meeting; install was scheduled 3 weeks later. Pre-install spot speeds averaged 25 mph; 30-day post-install measurement averaged 16 mph.

Current Market Reality
Corvallis's 2026 install costs sit close to Eugene equivalents -- both markets see slightly higher mobilization costs than Salem because the contractor pool is smaller. Multi-hump same-site bundling discounts are correspondingly larger. See speed hump cost guide for the full breakdown.
When to Choose a Hump vs Cushion in Corvallis
Corvallis Fire Department reviews calming devices on designated response routes. For most residential streets and private property, humps remain the default. For routes where Corvallis Fire flags a meaningful response-time impact, the conversation typically pivots to speed cushions. The speed cushions guide covers the wheel-track design.
Speed Hump Maintenance in Corvallis
Corvallis's wet winters and hot dry summers drive a similar degradation pattern to Eugene. Cojo's maintenance recommendation:
- Quarterly visual walk (paint, edges, hardware, signs)
- Post-winter inspection in March or April
- Mid-summer chevron-paint check (UV exposure can fade water-based paint)
- Repaint cycle every 18 months water-based, every 4 years thermoplastic
- Annual measurement-grade inspection with crack log
The speed hump maintenance reference covers the full lifecycle.
