consistent with the following criteria:
A. "Common open space," within the meaning of this article,
shall consist of a parcel or parcels of land or an area of water or
a combination of land and water within a development site designed
and intended for the use or enjoyment of residents of the development,
not including streets and off-street parking areas.
B. Common open space shall be land which is accessible
and in suitable condition for active or passive recreation, conservation
of environmentally sensitive areas or other recreation or natural
or visual resource conservation purposes.
C. The common open space shall be contiguous to the development
and shall be readily accessible from adjacent streets for pedestrians
and maintenance equipment. If separated from the tract by existing
roads, safe pedestrian access must be demonstrated.
D. Consideration shall be given to the arrangement and
location of common open space to take advantage of physical characteristics
of the site and to place common open space within easy access and
view of dwelling units, at the same time preserving environmentally
sensitive area and visual resources. Areas set aside for common open
space shall contain no structure other than a structure related to
outdoor recreational use and approved by the Township Board of Supervisors.
E. The ownership and maintenance of common open space
shall be made subject to such agreement with the Township, and such
deed restriction duly recorded in the office of Recorder of Deeds
in Chester County as may be required by the Board of Supervisors for
the purpose of preserving the common open space for such use.
F. The Supervisors may require a suitable portion of
the open space area to be usable and physically prepared for play
fields.
G. Common open space areas will be suitably landscaped
either by retaining existing natural cover and wooded areas and/or
by a landscaping plan for enhancing open space areas through plantings
which are consistent with the purposes of this article and which are
designed to minimize maintenance costs.
H. Common open space areas shall, where deemed appropriate
by the Board of Supervisors, make provision for pedestrian pathways
to be available for general public use in order to provide the potential
for interconnecting pathway systems within the Township.
I. Ownership and maintenance of common open space areas shall be in accordance with §
122-67F(2),
(3) and
(5) of this chapter.
J. The location, design and layout of common open space shall be in accordance with §

common open space areas, the following priority of values shall be
adhered to, unless specifically waived by the Board of Supervisors,
in delineating common open space areas:
(1) Wetlands, identified floodplain areas and stream valleys.
[Amended 7-10-2017 by Ord. No. 17-02]
