The Planning Board is set to decide soon whether a major rezoning proposal for the Mansfield commuter rail station will go before Town Meeting this spring or will wait until next year. “I think everyone’s supportive of it. We’re continuing to work on it and potentially will bring something this year or wait until next,” said Tom French, chairman of the Planning Board. French said a big challenge is harmonizing short-term responses to parking and traffic concerns with long-term solutions. The town is considering zoning changes to encourage transit-oriented development around the Mansfield commuter rail station, which is a regional traffic center, French said. The town has hired the BETA group engineering consultants to seek solutions such as a second access to the area, possibly crossing freight rail tracks, and improvements to Route 106. The deadline for submitting zoning articles is late March.
