A small community of about 5,051 residents, Brookline is located on the Massachusetts border, just west of Hollis. It is a town that has experienced much growth in recent years, but it remains a quaint, rural village. About 8,000 of Brookline’s 13,000 acres remain undeveloped. This is despite a recent growth spurt that prompted the Planning Board to introduce an ordinance limiting the number of building permits given out each year. That ordinance has been in place since 1994 and will likely remain on the books as a way to help Brookline preserve its rural character.
