A Planned Waterfront Residential Community (PWRC)
is established to promote and protect the public health, safety, property
values and general welfare of the Town of North Hempstead, and to
create the flexibility which is necessary to achieve environmentally
sensitive, economically beneficial and socially desirable development
on waterfront properties. The general comprehensive planning goals
for this district are to:
A. Promote the most appropriate, desirable, and suitable
use of land on sites which are unique due to size and waterfront location,
and to preserve open space consistent with orderly development of
a site.
B. Regulate development in such a way as to help preserve
the Town of North Hempstead's limited water supply and its surface
waters and other aquatic and natural habitat.
C. Allow for reasonable economic uses of land, consistent
with the planning goals for this district.
D. Encourage innovation and flexibility in the design
and development of waterfront property for residential use, while
ensuring that potential environmental impacts and other adverse impacts
are minimized.
The following definitions shall apply in this
article:
BUILDING HEIGHT

by the Building Commissioner or his/her representative prior to construction.
CLUSTERED DEVELOPMENT
Development that directs all built elements into selected
areas of a parcel by clustering development at higher densities on
a portion of the property, while allowing the remainder of the parcel
to be preserved as undeveloped, open space. Clustered developments
shall limit encroachment of the development upon environmentally sensitive
areas and reduce the amount of open land disturbed by development,
roads, and utility lines.
DWELLING UNIT

and toilet facilities, and only one kitchen.
FINISHED BASEMENT

of the adjoining ground, and which has internal circulation to the
floor above and/or plumbing fixtures.
GROSS FLOOR AREA
The sum of the gross horizontal area of all floors of all
structures on a site, as measured to the outside surfaces of exterior
walls. Gross floor area shall include attached garages, enclosed porches,
and roofed porches having more than 50% of the perimeter enclosed
or screened. Gross floor area shall also include finished basements
as defined in this section. Gross floor area in dwellings for areas
exceeding ten feet in height shall be equal to 1.5 times the actual
floor area.
LOT COVERAGE
The percentage of a lot(s) covered by the maximum projection
of any floor or roof of buildings or structures, excluding uncovered
swimming pools, uncovered terraces, uncovered porches, uncovered verandas,
uncovered decks and carports.

lots under common ownership, which may take the form of individual
structures with common utilities.
