Always best to get your information from the people who really know things. This is the response email from Sarah Raposa to the abutting neighbors providing the straight story.
Pete did a good job of summarizing the process and addressing your concerns. I think that some of the aspects of the failed Senior Housing Overlay District Bylaw may have trickled into your thinking on Points 4 & 5. The Rosebay units are indeed proposed to be perpetually affordable to seniors who income qualify (Point 4) and the Town will likely exercise its right to request 70% local preference (Point 5). The local preference step is done after a comprehensive permit is issued. We have done this for all of the 40B thus far. Affordability and local preference were issues that came up at special town meeting that we could not control through the zoning but are part of the 40B process.
Please let me know if you have additional questions or concerns.
