  • 2. Intent and purposes of districts.
    RESIDENTIAL DISTRICTS
    are intended to allow orderly development of residential dwellings designed to complement the natural features of the land, to promote suitable placement of buildings and related facilities in relation to the site and surrounding areas, with adequate living space and open space, to avoid overcrowding of land, to encourage good design, to avoid overburdening municipal facilities, and to insure compatibility with the immediate neighborhood and with the natural environment.
    R-10 DISTRICT
    is a residential zone with minimum lot size of ten thousand square feet (10,000 ft.
    2
    )
    R-20 DISTRICT
    is a residential zone with minimum lot size of twenty thousand square feet (20,000 ft.
    2
    )
    R-30 DISTRICT
    is a residential zone with minimum lot size of thirty thousand square feet (30,000 ft.

    COMMERCIAL DISTRICT C-1
    is established to provide areas for commercial establishments and serve community and Town-wide shopping and service needs.
    TOWN CENTER DISTRICT - TC
    is established to provide for a pedestrian-friendly commercial district that is more densely developed than the Commercial C-1 zone. Developments in the Town Center District shall, to the extent possible, contribute to an atmosphere of a traditional New England town center. While allowing mixed uses and planned unit developments, this district is more restrictive than the C-1 District in terms of discouraging or prohibiting uses that are not conducive to its purpose. Other than prohibited uses, all proposed uses in the TC District are subject to special use permits and design review.
