Presentation Agenda

• Program Parameters • Results of Pilot Program • Recommendations • Discussion

Critical Program Parameters

• Objectives • Improve safety and quality of life for people along local neighborhood and

residential collector streets. • Create a safer and more comfortable environment for pedestrians and

bicyclists – regardless of age or ability – to travel along and across local neighborhood and residential collector streets.

• Facilitate appropriate levels of local mobility for all roadway users and public service providers consistent with the context of the community.

• Provide acceptable levels of service along the city’s arterial streets so as to minimize diversion of vehicular traffic onto local neighborhood streets.

• Create opportunities for community enhancements, gateways or focal points.

Critical Program Parameters

• Administrative Policy • Developed and administered under Authority of City Engineer • Partnered with BPD and BFD early in the process • Community reviewed and commented • Authorization to proceed by Council Resolution No. 3643 – January 26, 2016 • Pilot Launched – March 1, 2016

• Funding Sources • Program Funding from General Fund, Transportation Fund • Project Funding from General Fund, Transportation Fund, Bond Funds

Critical Program Parameters

• Two Primary Issues • Speeding – Safety Issue • Cut-Through Traffic – Quality of Life Issue

• Initial Program Focus: Speeding • “Least restrictive that best mitigates” documented problem • Defined timelines and milestones • Defined criteria for Eligibility and for Ranking for Funding

Speeding Mitigation Process

• Eligibility • Traffic Study

• 85%ile Speed ≥ Speed Limit + 3 MPH, or • Five or more speed-related crashes in past 24 months

• Minimal impacts to Public Services (BFD can veto) • No conflicts with other projects • Not along multilane roadways or arterials

• Ranking for Funding • Based on 15 weighted criteria • Higher score = Higher priority • Eligibility ≠ Funding

• Unfunded requests expire after two years

Pilot Program Request Statistics

• Total Number of Accepted Requests 30 • Eligible for Funding 11 • Eligible but Incomplete1 2 • Ineligible

• 85%ile Speed or Crashes2 9 • BFD Veto 1 • Street Hierarchy 4 • Active or Pending Construction3 3
