Background
There has not been much official change in the plans for HCC on the north side. Construction has started on the Wilson Pacific site and the school board recently chose names for the buildingshttp://www.seattleschools.org/cms/One.aspx?portalId=627&pageId=438255
Here's the project status page with the latest excerpt:

May 2015
The City issued the Master Use Permit, the demolition permit and the grading permit. The notice to proceed was issued to Lydig, the contractor, regarding the early work bids for abatement, demolition, earthwork and murals relocation. The site has been completely fenced and abatement has begun in the gym and cafeteria buildings. Work continued on other construction documents and the easement application for 92nd Street on the west side of the site. Advertisements were made for the structural bid package. Lydig is prepping for the bidding process for mechanical, electrical and plumbing work.
And for completeness here's the Lincoln Building schedule:

Note: construction is still slated for June 2018
As you can see the current Cascadia building has less total capacity (660) already than next year's estimated student body size per Rina (800)
