Structures in the flood zone over 35 feet above grade require a special use permit.

(1)

Residential uses within an LB or MMU zone shall conform to the dimensional regulations of the nearest residential zone. Where residential zones of different dimensional regulations are equidistant, the more restrictive dimensional regulations shall apply.

(2)

In a multi-lot subdivision, the average lot size must be a minimum of 20,00 square feet. With prior planning board approval, some lot sizes may be reduced to a minimum lot size of 15,000 square feet, provided that:

a.

The average of the contiguous lots on the street frontage shall be 20,000 square feet; and

b.

The average size of all lots in the whole subdivision is 20,000 square feet or more.

(3)

Single-household, two-household, and multi-household dwellings are not permitted in the GB zone.

(4)

The planning board may allow up to a 25 percent reduction in frontage based on site conditions and/or road layout (i.e. on a lot fronting on a cul-de-sac, the frontage could be reduced, if deemed appropriate).

(5)

The planning board may allow an increase in the maximum lot coverage by structures from 50 percent up to 70 percent provided that:

a.

The first floor area is greater than 50,000 square feet; and

b.

The front of the building includes masonry and landscaping of good design.

(6)

There shall be a 25-foot planted buffer at the edge of the manufacturing district.

a.

The buffer shall be maintained in either natural or landscaped state and shall include trees, shrubs, bushes, and/or other understory growth to mitigate the impact of the manufacturing development on the residential district.

b.

The manufacturer or developer is required to discuss appropriate buffers with the director of community development.

c.

The residential side of the buffer shall be defined with a split rail fence, picket fence, or stone wall. Chain link fences shall not meet the requirements of fencing and shall not be placed on residential zone boundaries.

d.

If a chain link fence is necessary for the manufacturing facility, it shall be placed no less than ten feet from the residential zone boundary and within the buffer; however, access to the buffer for cleaning and maintenance shall be required.

The planning board may allow up to a 25 percent reduction in the distance from a residential zone boundary based on the site conditions and an increase in the size of the planted buffer. For each foot reduced in the distance from the residential zone boundary, the planted buffer shall be increased by one-half foot, to compensate for the increased impact on the residential district by the manufacturing use.

(7)

One side yard may be reduced to 20 feet, provided that the sum of both side yards is 50 feet or more.

(8)

See plan approved with the zoning amendment dated September 20, 2001.

(9)

Maximum building height shall be on the front half of the parcel in areas where the Metacom mixed use zone abuts a residential zone. Building height to the rear of building shall not exceed 35 feet where adjacent to a residential zone.
