To Protect and Assist Greenfield, New Hampshire

The Town of Greenfield, New Hampshire is located in the southern portion of Hillsborough County, bordering the surrounding towns of Peterborough, Hancock, Bennington, Francestown, and Lyndeborough. Like many other communities in New Hampshire, Greenfield has seen tremendous growth in population within the last several years. According to 2010 census data, approximately 2,000 residents are spread across 26 square miles. The Greenfield Police Department is in place to protect these residents.

Approximately 60 businesses fall under our jurisdiction, the largest of which include the Crotched Mountain Rehab Center, American Steel, the Barbara C. Harris Center, New England Forest Products, and the Greenfield State Park. The Barbara C. Harris Center, Brentwood Camp, Camp Winamac, and the State Park are seasonal businesses that can triple the town’s population. The Greenfield Elementary School educates young students between the ages of kindergarten and fourth grade, so regular patrols are made during the beginning and end of the school day to ensure safety. With traffic volumes constantly exceeding 2,500 vehicles on Routes 31 and 136, traffic safety is important on a daily basis. This traffic increases during the summer months, as the State Park brings an additional 1,000 people to town on any given weekend. We record over 1,200 traffic violations during the course of any given year, and we continuously work to enforce these laws. However, we are responsible for much more than traffic safety.

On a yearly basis, we respond to 2,500+ calls of varying degrees. We routinely respond to domestic disturbance calls, accident scenes, medical emergencies, and other situations. We have two full time officers, four part time officers, and an office administrator who work to satisfy these calls. We provide police service 365 days a year, and our officers are always prepared to respond to any emergency or call for service. At the Greenfield Police Department, we strive to connect with our residents and businesses on both a personal and professional level.

Bicycle Patrol: With 135 available campsites, the Greenfield State Park is one of the largest parks in the state. Due to the large amount of visitors that these sites can accommodate, we receive many calls to respond to the campground. To handle this increase in population and to deter illegal activities, we have received a yearly grant from the state to fund a bicycle patrol in the campground during the evenings. The officer on bicycle patrol acts as a deterrent for unlawful behavior such as illicit drug use and underage drinking. It also allows for the officer to respond to calls in the park, while the officer on patrol in town can remain available for other calls.

Lakes and Bodies of Water: In Greenfield, we have four main lakes: Sunset, Zephyr, Otter, and Powder Mill Pond. These four bodies of water attract swimmers, boaters, and fishing enthusiasts. These activities can attract hundreds of non-residents, and combined with the State Park visitors, this can effectively triple the town’s base population. Water sports include a number of hazards, so we routinely check these areas to ensure the safety of everyone involved.
