2 ISSUES & RISKS KEY ATTRIBUTES consistent with Sound Transit policies and procedures and may differ from the City of Seattle s Madison Street BRT project cost estimate Requires conversion of general purpose travel lanes to transit-only and may impact other streets; mitigation of general purpose traffic impacts could result in higher capital costs Potentially requires use of vehicles with left-side doors, which are not common and could result in higher maintenance costs Page 2 of 5

3 Sound Transit has developed a conceptual scope of work for this candidate project for the purpose of generating a representative range of costs, both capital and operating; and benefits, including ridership forecasts, TOD potential, multi-modal access and others. This information is being developed to assist the Sound Transit Board as it develops an ST3 system plan, including phasing of investments and financial plan, for voter consideration. Final decisions on project elements (e.g., alignment, profile, number of stations, station locations, and number of parking stalls) will be determined after completion of system planning, project level environmental review, and preliminary engineering during which additional opportunities for public participation will be provided. Therefore, this scope definition should not be construed as a commitment that all representative features will be included in the final developed project. Long Description: This project would connect the Colman Dock area in downtown Seattle with First Hill, Capitol Hill and the Central District using buses in exclusive lanes with signal priority and other features that improve passenger capacity and travel times. Sound Transit would make a capital contribution to this project. The City of Seattle would be the project lead and would be responsible for construction, permitting, environmental clearance, operations and maintenance. Assumptions: Approximately 2.3 miles of bus rapid transit running between 1 st Avenue in downtown Seattle to Martin Luther King Jr. Way in the Central District; service would operate in a running way consisting of a combination of center and side-running transit-only lanes, with a combination of stops on center islands and curb stops Sound Transit can only fund elements of this project that meet Sound Transit s legislative requirements in RCW for the provision of high-capacity transit service For non-motorized station access allowances, the stations are categorized as Urban and Urban/CBD stations; the stations near Seattle University and at the eastern terminus are also categorized as Major Bicycle Intercepts Environmental: City of Seattle will be responsible for completing all required project-level state and federal environmental reviews. Utilities: City of Seattle would be responsible for utility relocation as needed to complete the project, including fiber optics, sewer, water, overhead electric/communications, etc. Right-of-Way and Property Acquisition: City of Seattle would be responsible for all potential property acquisitions Potential Permits/Approvals Needed: City of Seattle would be responsible for all permitting. Project Dependencies: Coordination and agreement with City of Seattle Potential Project Partners: City of Seattle Transit partners serving project: King County Metro FTA Page 3 of 5
