Expert Review Panel for “Sound Transit 3” to discuss planning methodologies

An independent Expert Review Panel for Sound Transit’s Phase 3 (ST3) planning for the Regional Transit Long-Range Plan will meet on November 9 and 10 in Seattle to review cost estimating, ridership forecasting and other methodologies, along with recent public outreach activities. The 10-member panel was appointed by Governor Jay Inslee, the chairs of the state House and Senate transportation committees, Rep. Judy Clibborn and Sen. Curtis King, and Secretary of Transportation Lynn Peterson, in accordance with state legislation (RCW 81.104.110).

On Monday, November 9, the panel will convene at 9:00 a.m. at the Mayflower Park Hotel Plymouth Room, 405 Olive Way in Seattle. The day’s agenda includes discussion of capital cost estimating and cost management, operations and maintenance costs, integration with other transit operators in the region, and the updated ST3 potential project list. There will be time for public comment in the late afternoon.

On Tuesday, November 10, the panel will reconvene at 9:00 a.m. at the Pike Place Market Economy Market Building, Atrium Loft, on the 3rd floor at 93 Pike Street in Seattle. Discussion will include ST3 project templates, and ridership, population and employment forecasting, along with updates on financial planning and public outreach activities. There will also be a time for public comment in the afternoon.

The role of the panel is to pose and assess critical questions, help guide the preparation of the Sound Transit 3 Plan through the panel’s review of key methodologies and assumptions, and ensure the assumptions in the plan are appropriate and reasonable. The panel’s technical review of the Sound Transit 3 Plan is necessary to guarantee that Sound Transit’s Board can make appropriate decisions for Sound Transit 3 investments in the region’s high-capacity transportation system.

The 10 panel members were selected from across the nation. Collectively their expertise spans key technical areas, including project cost estimating, capital finance plan review, ridership forecasting, modal analysis, legal and political architecture of Sound Transit’s legislative charter, environmental impact statement preparation, local design and constructability, and transit operations and maintenance.
