  1. Traffic Calming Devices Workshop Prepared by City Engineering Department

  2. Project Goals • Purpose of workshop • Types of TDCs Available • Considerations • Recommendations and Analysis • Informational Items • NE 8th & 10th Avenues Considerations • Discussion • Review existing City policy

  3. Purpose of Workshop • Discuss the different types of TDCs available and their applicability for use throughout the City • Solicit input of preferences from the community and the Commission • Discuss and comments

  4. Types of TDCs Available • Passive Controls • Warning signs • Speed limit signs • Caution signs • Speed radar signs • Radar boards • Police speed enforcement

  5. Types of TDCs Available • Active Controls - Vertical or horizontal deflections • Speed bumps • Speed humps • Speed pillows • Speed tables • Raised intersections • Intersection islands • Roundabouts • Splitter islands • Narrowed lanes • Lane offsets

  6. Considerations • Impact to neighborhoods • Thru traffic • Emergency vehicles response times • Fire rescue response times • Garbage truck pickup • Delivery vehicles • Pedestrian safety • Aesthetics • Cost of implementation and maintenance • Transfer of problems to other areas • Noise impacts due to stopping and accelerating

  7. Discussion of the following - Passive Controls - Active Controls - Vertical or horizontal deflections Speed bumps Speed humps Speed pillows Speed tables Raised intersections Intersection islands Roundabouts Splitter islands Narrowed lanes Lane offsets Recommendation and Analysis

  8. Passive Controls

  9. Speed bumps & humps

  10. Speed pillows

  11. Speed tables

  12. Raised intersections

  13. Intersection islands

  14. Roundabouts

  15. Splitter islands

  16. Narrowed lanes

  17. Lane offsets

  18. Informational Items • Present TDCs being installed - Speed Tables per BCTD Standard • Coordination with Fire and Police - Emergency response impacts • Majority of installs based on residents request • TDCs have a positive impact on crime prevention

  19. NE 8th and NE 10th Avenues Considerations • Options to conversion from one way to two way traffic - Install speed tables on each avenue to slow traffic - Eliminate the NB thru movement from the 10th Ave. signal to reduce cut thru traffic - Eliminate the SB and NB left turns at 8th Ave. leaving only the WB left for Sage plaza or eliminate the signal all together

  20. Discussion • Discussion of presentation and input from residents and Commission

  21. Review Existing City Policy • Review of existing policy for potential changes
