Five years ago, the City of Somerville began a planning process to develop a master plan for Davis Square. The process has involved many levels of citizen input, some trial runs of new ideas, forward-thinking consultants and dedicated staff. Today, I attended a presentation of a draft master plan, from the Office of Strategic Planning and Community Development. They set up roughly six stations and had different personnel discuss a specific aspect of the master plan at each station. Very interesting conversations to be had.
