  • 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


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


Passive Controls


Speed bumps & humps


Speed pillows


Speed tables


Raised intersections


Intersection islands


Roundabouts


Splitter islands


Narrowed lanes


Lane offsets


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


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


Discussion

  • Discussion of presentation and input from residents and Commission


Review Existing City Policy

  • Review of existing policy for potential changes
