Quality of Life Findings

Central Neighborhoods:Central Neighborhoods:Generally in favor of removing reverse lanes

Many felt: Reverse lanes inhibit accessLanes are unsafe and signs are

confusing

Northern Neighborhoods:Northern Neighborhoods:Generally in favor of keeping reverse lanes

Many felt: Lanes are safe and reduce travel

timeReverse lane signs are

understandable

City Council Action

Form citizen Ad hoc Task Force to work with City staff to review all available studies conducted on the reverse lane issue, consider new alternatives and, through consensus, bring forth written recommendations to the City Council

Task Force Recommendations

If reverse lanes remain, the task force recommends that the City should:

Improve reverse lane signingIncluding time-of-operation lights/beacons

Increase enforcement Implement new education campaign Explore school crossing opportunities and new

bus bays Explore additional left turn opportunities at

some signalized intersections Estimated cost of changes $4-6,000,000

Final City Council Decision

City council approved task force recommendations.

Staff is developing implementation plan

Implementation Schedule: 2012-13

Traffic Calming

Speed Humps

Traffic Circles and Islands

PhilosophyTraffic Safety versus Quality-of-Life

Traffic safety – Crash history Design flaw

Traffic calming – Speed, volume, noise Intruder traffic

QUALITY OF LIFE

Traffic Calming Requires Resident Approval

Traffic Mitigation ProgramPROCEDURES

Program designed around three distinct phases all of which require some level of neighborhood involvement

PHASE I Initial Study

PHASE II Temporary Installation

PHASE III Permanent Installation

Phase I: INITIAL STUDY

Neighborhood Contact Initial Traffic Volume and Speed Study conducted If location qualifies a Temporary Installation Petition is developed

Phase II: TEMPORARY INSTLATION

Staff develops temporary traffic mitigation plan If plan is approved, City installs temporary plan Traffic patterns are studied

36th Street at Rosemonte DriveHearn Road East of 12th Street

Phase III: PERMANENT INSTALLATION

Staff reviews results of temporary plan with residents Residents are petitioned for permanent installation City installs permanent structure
