Attend meetings this week in Cambridge and Somerville

 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.
