Since Sound Transit released the DEIS for the new West Seattle-Ballard extension, stakeholders have been poring over the findings and submitting their comments. One major group of stakeholders is the Chinatown-International District (CID) neighborhood, which recently came out in full force either against the 5th Avenue alternative or against all options entirely.
Mike Lindblom has a detailed scoop:
Neighborhood advocates insist the station must go a block farther west, under Fourth Avenue South near South King Street, with the highways and sports stadiums. That would lessen the impact on an area that’s been sacrificed for generations to regional construction.
. . .
But choosing Fourth Avenue possibly creates a traffic nightmare, because builders would demolish and replace the six-lane elevated street. In that scenario, about 15,000 daily car and bus trips, and stadium surge traffic, must be detoured during six years of partial road closures, compared to only 5,000 on Fifth for a 2½-year closure.
Total construction time on Fourth Avenue is estimated at nine to 11 years, a couple of years longer than Fifth.
It’s important to remember that while Sound Transit has not yet identified a preferred alternative for this segment, it finds itself in the usual quagmire of picking and choosing between neighborhood impacts, ridership, and cost. The 5th Avenue option certainly has superior neighborhood and transfer access, but construction would come at a great cost to the CID.
Back in April, Seattle Subway endorsed an even-shallower version of the 4th Avenue shallow option (CID-1a). Their proposal would effectively be at-grade, flush with the BNSF tracks and the 4th Avenue viaduct rebuilt over it. It’s not clear how compatible this super-shallow option would be with the deep Midtown Station profiles that are currently on the table.
While not without its own problems, a 4th Avenue alternative does open creative possibilities for re-doing the entire King Street Station-IDS hub, which is currently a patchwork of office buildings, limited walkways, and pedestrian-unfriendly 4th Avenue. A lid over the BNSF/Sounder tracks and repurposing Union Station are some of the ideas worth considering.
