Standard material for any sidewalk or walkway shall be Portland cement
concrete (PCC). However, if approved by the Town, other materials,
such as brick, asphalt, or other stable, firm, slip-resistant material
surfaces, may be used. In addition, alternative paving materials that
are environmentally sensitive and reduce impervious areas may be considered
by the Town. Minimum thickness can vary according to materials, but
must be at least four inches for Portland cement concrete on four
inches of graded aggregate base course (GABC). A minimum thickness
of six inches of PCC and six inches of GABC is required at entrance
and driveway areas.
