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.
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.
