The first of four public presentations scheduled by the town’s consultants to present specifics about various aspects of the proposed $1 billion resort casino planned by Foxwoods Massachusetts will be held on Wednesday and will focus on “traffic patterns, plans, and infrastructure.” The second, to be held July 17, will focus on “water and sewer impacts of the project and infrastructure upgrades.” The third presentation, on July 24 will focus on “social and economic impacts,” and the fourth, on July 31, will center on the “environment and site design matters” and will include a general overview of the project. The gaming casino and entertainment center would include a luxury hotel, retail space, and restaurants. The presentations will all begin at 7 p.m. and be held in the auditorium at Milford High School. The sessions will provide an opportunity for the Board of Selectmen to get answers to specific questions before deciding whether to enter into a host agreement with Foxwoods. Successful negotiations of that agreement, passage of a town referendum, and a change in zoning at the site by Town Meeting are all required before the Massachusetts Gaming Commission will consider it for the sole casino resort license for Greater Boston to be granted early next year.
