The project, called Riverside at Pembroke, would build 100 two-bedroom homes for people over 55 on the 125 acres of land owned by Robert Meissner of DHB Homes. Meissner’s team requested a zoning ordinance to structure the development as a cluster of homes, rather than a traditional subdivision. The Zoning Board denied the cluster variance because members did not feel there was proof of hardship. The cluster variance would also allow for over 28 acres to be put in a conservation easement, he said. Then, in 2016, DHB Homes submitted a second proposal, which it ultimately withdrew because the town didn’t have the sewer capacity for the project.
