MBTA site change; green roofs

Land Use Committee and Planning Board joint hearing, 6:30 p.m. Thursday. The two committees hear public comment on a proposal to change the zoning at 200 Inner Belt Road, East Somerville, which has been used since 2014 as a temporary manufacturing facility to service construction of the green line extension for the MBTA. The owners of the site seek a change to High-Rise zoning from Commercial Industry. The boards also hear a request from David Einis, owner of 0 White St. Place and 14 White St. Place in Porter Square, to change the zoning of his properties to Urban Residence to allow for a new housing development on the sites. In addition, city councilors Ben Ewen-Campen and Jake Wilson discuss their proposed amendment to the zoning ordinance that would require planted roofs on certain new or renovated buildings. Also known as green roofs, these vegetative layers help with stormwater management, reduce pollution and save energy. Watchable by Zoom videoconferencing.
