Ballard Station Workshop

On January 11th, Sound Transit held the second Interbay-Ballard workshop to prepare for a route selection by the Board in March. The workshop summarized the findings from the first workshop and online responses, and then presented a few new options for tunnel stations along 14th and 15th Ave NW. These options were to address some of the Board's concerns and to reduce cost with the goal to deliver the Ballard extension closer to 2037 rather than 2039. The presentation also provided more details on construction impact.

For Ballard, Sound Transit is trying to refine the options by limiting property acquisition costs and improving station access, in particular from both sides of Market St.

1. Sound Transit could save $100 million by locating the station on the East side of 15th Ave NW. The main entrance would be in the middle of the station on the Southeast corner of Market St. A pedestrian tunnel would also connect to a Southwest entrance and could potentially be extended to another entrance on the Northwest corner for an additional $30 million. There would also be small emergency exits on the South and North ends of the platform.
2. Similarly, they could locate the line right under 15th Ave for similar savings. Lanes on 15th Ave would need to be reduced for up to 4 years. By pushing it further North straddling Market St, they might be able to add an entrance North of 56th Ave.
3. By locating the station on the East side of 14th Ave straddling Market St, they could avoid acquisition of Safeway and save $140 million. They pointed out it would reduce the opportunity for TOD and make the entrances less visible.

One of the concerns with the 14th Ave station is that riders would need to cross 15th Ave. They presented various ways to improve the crossing using bulbs, a pedestrian bridge or a pedestrian tunnel. They also envisioned an underground retail concourse combined with TOD which would connect the 14th Ave station underground and extend under 15th Ave for an additional cost of up to $100 million.

Even though during the DEIS public input many residents had requested better access to downtown / historic Ballard, they did not look at alternative stations along Tallman Ave, Russel Ave, Market St, or 56th St. When I asked why not, they responded that they had not looked at those but that a station requires a large enough staging area, and they try to avoid impacting historical buildings.

During their December 12th workshop Sound Transit had presented a few alternatives for the Interbay section to address earlier concerns. Sound Transit now presented some new findings:

1. A station under Dravus St would require a partial closure of Dravus for 18 months but save $30 million.
2. A Mercer Place tunnel portal turned out to be infeasible though the alternative station locations may also work with the tunnel portals already under consideration.
3. More tunneling with a single consolidated station along 15th Ave may reduce impact and simplify transit connections but reduce neighborhood connectivity and increase cost by $210 million.
