Transportation Kansas 3 Minutes Read ยท published February 21, 2026 Flag of Kansas

In Kansas City, Kansas, residents and property owners can request traffic calming changes such as speed bumps, speed humps, or roundabout reviews through the Unified Government process. This guide explains who is responsible, the typical steps to request changes, enforcement and penalties, and the official points of contact you will need to pursue a petition or complaint.

Overview of the Request Process

Traffic calming requests are managed by the Unified Government Public Works - Traffic Engineering division and follow local ordinances and engineering standards. Petitions, field studies, and traffic counts are commonly required before any physical change is authorized. For local procedures and contacts, see the Unified Government Traffic Engineering page [1] and the official ordinances portal [2].

Gather signatures and photos before contacting Traffic Engineering.

Key steps the city typically follows

  • Submit a written request or petition to Traffic Engineering with location, reason, and supporting evidence.
  • Traffic Engineering performs a site assessment, which may include speed and volume counts and collision history review.
  • Engineering evaluates options: signage, speed humps/bumps, traffic calming islands, or roundabout feasibility.
  • If a change requires ordinance approval or funding, the item may proceed to the appropriate committee or Unified Government Commission.

Penalties & Enforcement

Enforcement for improper installation, alteration, or damage to traffic-calming devices and traffic control devices is handled by the Unified Government Public Works and law enforcement as specified in the municipal code and enforcement rules.
