Sound Transit recently released an addendum to their design and environmental analysis for S. 200th St. station. It updates a 2005 document. The map above nicely summarizes the changes. In ST agency-speak this segment is “South Link” while the other two (potential) stops beyond this — Highline Community College and Redondo/Star Lake — are the “South Corridor.” Key changes to the plan:
- Increasing the number of parking spaces from 630 to 1,100. This change is driven by a parking study that SeaTac law requires. There are three different configurations (1 garage, 2 garages, or garage plus lot) that might reach this total. The garage would have ground-floor retail/commercial in accordance with SeaTac law.
- Add a pocket track just south of the station, which would allow ST to park an additional train at the terminus.
- Shift the guideway to keep speeds at 55mph and improve safety at some intersections.
- Changes to the planned road revisions, including better bike/ped/bus facilities on S. 200th st.
- Move the station 40 feet to the west to avoid power and gas lines.
I’ve emailed Sound Transit to ask what the cost impact is.
