Traffic Calming Measures

Our goal, as a City, is to protect the safety of pedestrians, bicyclists and other motorists. To that end, the Mayor and Board of Aldermen have worked with City staff, to coordinate optional traffic-calming measures to help reduce residential speeding.

At the Board of Aldermen meeting on July 12, 2017, a resolution was passed that aims to “reduce negative effects of motor vehicle use, alter driver behavior and improve conditions for non-motorized street users, [which] may be exercised within residential areas of the City to moderate the speed of motor vehicles.”

The resolution identifies measures to reduce speed and traffic volume, establishes criteria for the utilization of traffic calming measures, and establishes procedures for the development and implementation of these measures on a case-by-case basis. Per this resolution, the City will implement three tiers of traffic calming measures.

  • Tier 1: This tier is triggered by a resident concern. Tier 1 traffic calming measures include, but are not limited to, enforcement of the posted speed limits, placement of the City’s SMART trailer, distribution of traffic safety brochures, and/or posting of “Keep Kids Alive, Drive 25” signs, which may be purchased by a subdivision and will be installed by the City.
  • Tier 2: Traffic calming measures for this tier include, but are not limited to, the adoption of a Double Fine Zone ordinance, the posting of Double Fine Zone signs and increased enforcement of the posted speed limits. Implementation of Tier 2 requires a petition submitted by at least 51% of the property owners within a subdivision or a letter of support for the implementation of Tier 2 from the trustees or directors of the subdivision’s Home Owners Association. 
  • Tier 3: Traffic calming measures for Tier 3 may include a pavement dip. Implementation of Tier 3 traffic calming measures can only be completed in subdivisions where at least 50 lots will be served by the measures and only after the City and the HOA have attempted traffic calming through Tier 1 and Tier 2. Implementation of Tier 3 requires a petition submitted by at least 67% of the property owners within a subdivision requesting one of the designated Tier 3 traffic calming measures and an HOA letter of support. Additional criteria are required for this tier, including final approval by the City’s Public Works and Police departments. For Tier 3, the subdivision shall agree to pay 50% of the cost.

Additionally, to implement both Tier 1 and Tier 2, a speed study must be completed by the City that demonstrates that the majority of drivers are going 30 mph, or greater.
