any preliminary or final plat and shall be subject to the following
minimum requirements.
(1)
The minimum land area that shall be devoted to open space shall
consist of an area equal to the net area of the development minus
the maximum number of lots having the maximum lot size. Open space
in excess of the minimum may also be included in open space.
(2)
Open space shall not be further subdivided.
(3)
Open space shall not be developed except as provided below.
(4)
Open space may be included in the net acreage of the development
for density calculations only if it is used as:

of required improvements and indicate when the improvements will be
installed;
(d)
The subdivision plat for record identifies the boundaries of
the dedicated tract within the cluster development;
(e)
The deed of dedication for public use shall provide that in
the event the property shall no longer be used for that purpose, it
will revert to the trustees of the subdivision in which it is located
as common land. The trust indenture required herein shall provide
for the manner in which the common land shall be treated.
(7)
Open space not dedicated to the
public shall be titled to subdivision trustees, as provided herein.
(a)
In developments where common ground which may include open spaces,
recreational areas or other common ground are provided and the acreage
of which is included in the gross acreage for density calculation
purposes, a trust indenture shall be recorded simultaneously with
the final plat. The indenture shall provide for the proper and continuous
maintenance and supervision of said common land by trustees to be
selected and to act in accordance with the terms of such indenture,
and the common land shall be deeded to the trustees.
(b)
In addition, the trust indenture shall contain the following
provisions:
(i)
That the common ground, including open spaces, recreational
areas or other common ground, shall be for the sole benefit, use and
enjoyment of the lot or unit owners, present and future, of the entire
cluster development or that the common ground may also be used by
residents outside the cluster development.
