Sara is named for Boston’s South End Neighborhood, which was another of Boston’s many landfill projects. The South End was built before technology allowed builders to construct concrete and steel pilings. Because of this, engineers drove wooden pilings into the dirt to a level just below the water table. This created a solid base on which to build. Once bordered by the famous Boston & Providence Railroad, most of the streets in the South End are named for towns that were serviced by those railroad lines. Sara was christened by Mayor Menino during Boston’s 2006 Pridelights ceremony.
