Reuse of an historic educational or religious
building for any residential use, live/work space,
or office; provided, however, that no more than
20% of the floor space of the building shall be
used for medical, banking or any offices where a
primary function is to provide services to retail
customers or individuals; and further provided
that such use is within the footprint of the existing
building. The existing building may be expanded
to accommodate elevators and stairwells,
provided that all historical contributing portions
of the building are retained and covered with an
historic preservation restriction granted to the
City of Northampton in a form acceptable to the
Planning Board, with input from the Historical
Commission, as preserving the key character-
defining features visible from the road (and not
necessarily meeting federal or state preservation
standards for the entire building). Portions of the
building that are not part of the original
architecture of the building and which do not
contribute to the historical or architectural
significance of the building as determined by the
Planning Board, with input from the Historical
Commission, may be demolished.

planned within a FEMA-mapped floodplain,
it must be shown to be engineered to
withstand expected floodwaters or it must be
engineered to include a breakaway that opens
during flood conditions.
