§ 231-1. Policy and purpose.
In the interest of safety, and in recognition of the increased density of population throughout the Town of Woodbridge, it shall be the policy of the Town to discourage the use of firearms in the Town, and to prohibit hunting of any kind on Town-owned land, particularly Town-owned land dedicated to passive recreational use or land preserved for open space. It shall further be the policy of the Town of Woodbridge to encourage private landowners to strictly comply with state regulations regarding the use of firearms on private property and to refrain from permitting hunting on private property, particularly on private property that abuts or adjoins Town-owned land. In furtherance of these goals, this chapter is amended and restated as follows.
§ 231-2. Restrictions on discharge of firearm, crossbow or longbow.
No person shall discharge any firearm, air gun, air rifle or crossbow or longbow in the Town in such a manner or under such circumstances as to place any person or property in jeopardy of injury therefrom. The discharge of any of said weapons within 500 yards of any dwelling or building accessory thereto, or any person not in the company of such person carrying said weapon, or without a permit as required by state statute or regulation, shall be prima facie evidence of a violation of this section.
§ 231-3. Town property.
No hunting or target shooting or any other activity involving the discharge of a firearm, air gun, air rifle or crossbow, longbow or other weapon shall be permitted on any Town-owned property. The possession of any loaded firearm, air gun, air rifle or crossbow, longbow or other weapon on Town-owned property shall be prima facie evidence of a violation of this section.
