*The minimum lot size is ten thousand (10,000) square feet if adjacent to open space and fifteen thousand (15,000) square feet if not directly adjacent to open space.

**The maximum density is no more than one (1) single-family dwelling per five (5) acres, except that if the Town approves a conservation density bonus, the maximum density allowed shall be no more than one (1) single-family dwellings per two (2) acres. This must have at least fifty percent (50%) of the land preserved as agricultural lands or open space.

2. Commercial, Industrial, Agricultural, Public and Hazard Overlay density and dimensional standards:

Notes to Table 3-5

1The building height limitations shall not apply to church spires, belfries, cupolas, or domes not used for human occupancy, nor to chimneys, water tanks, silos, nor to public building or structures located more than one (1) foot horizontally from the property line for each foot of building height.

3. Setback requirements.

a. On "double frontage" lots (see Figure 2-5 in Article 2 Section 6), both streets shall be considered street frontages for purposes of calculating front yard setbacks.

b. On corner lots, all sides of the lot with street frontage shall meet the applicable front yard setback.

c. For purposes of setback calculations, a two-family dwelling shall be construed as one (1) building occupying one (1) lot.

d. When residential lots are adjacent to, and the houses do not face an arterial street, the lots shall be a minimum of one hundred fifty (150) feet deep and direct access to the street shall be limited. The setback to the house shall be a minimum of seventy-five (75) feet. Additional buffering techniques must also be applied such as those outlined in Section 2.15.

e. Permanent features allowed within setbacks shall include:

(1) Cornices, canopies, eaves or other similar architectural features if they extend no more than two (2) feet into a required setback and if they do not encroach into or overhang an easement.

(2) Steps or ramps to the principal entrance and necessary landings, provided that they do not extend more than six (6) feet into the required setback.

(3) Landscaping.

(4) Fences and walls, subject to height and other restrictions per Article 2 Section 16.

(5) Utility service lines to a structure and utility lines, wires and associated structures within a utility easement.

(6) Fire escapes, provided that they do not extend more than six (6) feet into the required setback.

(7) Patios, porches and decks, provided that they do not extend more than five (5) feet into a required front or rear setback or five (5) feet into a required side yard setback adjacent to a street, provided that they do not encroach into or overhang an easement or property line and do not obstruct any sight distance triangle.
