If citizens are interested in having speed humps installed on their street, the following process applies:
- A street must be classified as a two-lane, local residential street.
- A street’s width must be less than or equal to 40 feet.
- Average Annual Daily Traffic (AADT) volumes should be greater than 1,000.
- The speed of 15% of the vehicles should be equal to or greater than five (5) miles over the posted speed limit.
- Grade is less than or equal to 8%.
- Horizontal radius of street is less than or equal to 300.
- Street’s current speed limit should be posted as 25 mph if it is a local street, or 30 mph if it is a neighborhood collector.
- Street should not be a primary emergency medical services route—CDOT will contact EMS departments in the area of the request to determine if the humps will interfere with a majority of their emergency response calls.
Resident Petition – If a street qualifies for speed humps, the following will be required from the residents:
- A 60% petition of all property owners on the street, including adjoining cul-de-sacs off the street.
- A letter of endorsement from the neighborhood association is required, if one is listed on the Charlotte-Mecklenburg Planning Commission “List of Neighborhood Contacts”.
Prioritization for Installation – After the request is submitted to CDOT, the street will be evaluated and rated for priority. Petitions are mailed to citizens of the highest ranking 35-40 streets in January each year. Installation is accomplished by annual contract in late Spring.
