Following a contest, Mary O’Donnell has chosen the name The Greenway Village at Kingston for a sustainable residential development planned for a 100-acre site she owns next to the town’s MBTA station. O’Donnell said the development of 250 to 300 units will make use of solar, wind, and geothermal energy, reclaim rainwater on site, have its own septic treatment system on site, and include space for a nonprofit food cooperative that grows food. “It makes so much sense,” O’Donnell said last week. “The land is perfect for it.” Families will reduce their transportation needs because they live close to the railroad station. The property already has a permit for a Chapter 40R smart growth development because a developer planned to build a 700-unit affordable housing development on the site. The developer withdrew several years ago because of the downturn in the real estate market. O’Donnell said the planning stage for a fully sustainable development on the site would likely continue for the rest of the year.
