The Planning Board at its meeting Thursday will resume a public hearing on two proposals for adjacent developments on Greenleaf Way, a private street in Northwest Park, just off Network Drive. Primrose Schools Support Center seeks a special permit to build a 12,000-square-foot child-care facility at 60 Greenleaf Way, and Digital Federal Credit Union seeks three special permits to open a regional banking center at 70 Greenleaf Way. Also Thursday, the board will continue a hearing into a request by Lisciotti Development Corp. for three special permits and site-plan approval for a mixed-use project at 201 Middlesex Turnpike. Lisciotti wants to construct a 9,000-square-foot building, about 2,500 square feet of which would be occupied by a Starbucks with a drive-through window, according to Don Benjamin, senior town planner. The board will also resume a public hearing into an application by Caleb and Kareena Kirby for approval of a single-lot subdivision plan for 50 Margaret St. The Kirbys plan to construct a single-family home there, according to Benjamin.
