We run speed-hump installs across Salem, Keizer, and West Salem — South Salem residential streets, Salem-Keizer School District drop-off loops, the apartment complexes along River Road. Some go through Salem Public Works' residential traffic-calming program; the rest we handle directly with HOA boards or property owners. What's below: Salem's code, the neighborhoods we cover, recent projects, and what 2026 pricing actually looks like.
For a public Salem street, Salem Revised Code (SRC) Chapter 79 (Streets) governs work in the right-of-way and the Salem Public Works traffic-calming program sets eligibility and approval. For a private street, the HOA board or property owner authorizes the work directly under Oregon Revised Statutes Chapter 94. Cojo handles the install scope on either path.
For school-zone installs, the Salem-Keizer Public Schools transportation office and the Oregon Department of Education school transportation rules add a transportation-director sign-off.
Cojo installed a 12-foot parabolic asphalt speed hump on a private driveway in West Salem serving a 96-unit apartment complex. Pre-install 85th-percentile speeds at the building entrance averaged 24 mph; 60-day post-install measurement averaged 17 mph. No resident vehicle damage complaints over the same window.
Cojo installed a 12-foot parabolic hump in the parent drop-off loop at an elementary school in West Salem in coordination with Salem-Keizer Public Schools transportation. The principal had logged 40+ near-miss reports over the prior school year. Drop-off-loop spot speeds dropped from 14 mph to 6 mph. The district extended the design to two adjacent elementary schools in spring 2026.
Cojo installed a 14,000-sq-ft retail center striping refresh in South Salem that included a single speed hump on the customer-pickup-lane approach to the storefront crosswalk. Pre-install spot speeds in the pickup lane averaged 17 mph; 30-day post-install measurement averaged 8 mph.
Cojo's annual inspection covered an apartment complex in South Salem with 6 asphalt humps installed in 2019. The pass found 4 humps with worn chevrons, 2 humps with edge cracking, and 1 hump with crown-height loss. The crew refreshed all 6 with thermoplastic, sealed 38 linear feet of cracking, and replaced the 1 failing hump in a single 2-day mobilization.

Salem's 2026 install costs run roughly 5 to 10 percent below Portland equivalents because traffic-control overhead and labor rates are slightly lighter. Multi-hump same-site bundling drops the per-hump price 25 to 35 percent. See speed hump cost guide for the full pricing breakdown.
Salem Fire Department reviews calming devices on designated response routes. For most residential streets and private property, a hump is the default. For routes where Salem Fire flags a meaningful response-time impact, the conversation typically pivots to speed cushions. The speed cushions guide covers the wheel-track design.
