How traffic calming and speed bumps work in Mesa

Mesa evaluates street safety using traffic volume, speed data, and neighborhood support. Engineering criteria and a prioritization process determine whether a location qualifies for physical measures like speed bumps or softer measures such as signage and pavement markings.

  • Request evaluation by Public Works/Transportation via the city's traffic calming program and petition process.Official program[1]
  • Enforcement of speed limits is carried out by Mesa Police Department; citations follow state law and local ordinances.Police traffic unit[2]
  • Installation decisions are made by Transportation Engineering after engineering study and neighborhood input.
  • Permanent physical changes require coordination with utility owners, ADA compliance reviews, and a city construction permit.
