The two proposals highlighted in green have been selected for further interviews. That's per an email from Asst Town Manager Dawn Blobaum who is managing the project for Town Hall.
The proposals by Blue Heel and Luminous (aka Davidson Development Partners) clearly met the RFP's goals for mixed use development, so it seems understandable why these were chosen. See site plans below.
As for the schedule, things could move very fast. According to Blobaum...
"Our hope is to be ready for a vote at the March 14 board meeting.
We are working on a date and venue for a public meeting prior to the February 28 board work session. When we get a determination on that we will get information out about it.
The selection committee includes several neighborhood representatives; planning board, livability board, and design review board representatives; two commissioners; and staff."
The two electeds on the selection committee include Commissioner Rodney Graham and Commissioner Stacey Anderson.
