Committee Recommendation


• Two‐phased approach, starting with primarily speed control 
  (Scenario I) and moving towards volume control if results are not 
  satisfactory.

• Conduct field tests to measure impact to Fire Department 
  response time. 
Field Tests

• Fire Department brought trucks and ladders to the site.

• Staff placed cones to represent circles and median islands.

• Fire Department did “test” runs with and without the devices.

• Circles added 25 seconds per location, compared to 5-8
  seconds as national norm.
Circle Dimensions
Key Learnings

• Fire Department has a valid but very narrow mission.

• Someone at the City (manager or council) needed to balance
  Fire Dept needs against other public safety and livability needs.

• Field tests should be done with actual devices or very similar.
