Before Ordering Speed Bumps: What Problem Is Your Parking Lot Trying to Solve?
Before ordering speed bumps for a parking lot, describe the behavior you want to change and where it happens. Bring a marked property map, specific observations, and a list of people who use the area. Ask for a site-specific review before committing to a device, quantity, or installation location.
Turn a complaint into a reviewable location
Instead of submitting only “cars go too fast,” identify the aisle, direction of travel, and time of day involved. Note whether the concern happens beside an entrance, across a walking route, or along a shortcut through the property. Separate witnessed events from secondhand reports and avoid presenting an estimated speed as a measurement.
For a Middle Tennessee shopping center, church, or workplace, a useful starting document is a single annotated map. Include entrances, delivery areas, pedestrian routes, and the location of each reported concern. Ask the reviewer whether additional observation or speed data would help before discussing construction.
Ask for a choice, not just a price per bump
ITE groups traffic-calming measures into several categories, including vertical changes, horizontal shifts, narrowing, and closures. Its reference material is informational, not a recommendation that a particular measure belongs at your property. A product name alone should not settle the choice.
Ask the person evaluating the site to explain the proposed approach, the alternatives considered, and the information still needed. Include these questions in the request: Who reviews delivery and emergency access? How will pedestrian routes and drainage be considered? Who identifies any required approvals? Request an explanation of the proposed layout rather than copying dimensions from a photograph.
Put operating responsibilities beside the installation scope
Before requesting a final quote, give the reviewer your delivery schedule and the contact responsible for grounds and winter maintenance. Ask for the proposal to distinguish the physical installation from any associated pavement repair, markings, signs, and ongoing upkeep. Record who will answer tenant questions and who will receive reports after installation.
Milliken lists commercial parking lot paving, repairs, and striping among its asphalt services. When discussing a speed-control concern, ask which parts of the proposed work it can provide and whether separate traffic-design review is needed. Do not assume a paving quotation includes that review unless the scope says so.
Frequently asked questions
Should I choose the number of bumps before requesting a review?
Describe the locations and concerns first. Ask the reviewer to justify any proposed number and placement through the site assessment rather than treating your initial sketch as an approved layout.
What should I keep after the work is complete?
Keep the accepted layout, final scope, maintenance responsibilities, and a contact for follow-up concerns. Agree on who will review whether the original operating problem has improved.
