A. General standards. The arrangement, character, extent,
width, grade and location of all streets shall conform to the Ridley
Township Comprehensive Plan, as adopted, and shall be considered in
their relation to existing and planned streets, to topographical conditions,
to public convenience and safety and in the appropriate relation to
the proposed uses of the land to be served by such streets. Where
not shown on the Ridley Township Comprehensive Plan, design standards
of streets shall conform to the provisions found herein.
B. The arrangement of streets in new subdivisions shall
make provisions for the continuation of existing streets in adjoining
areas.
C. The arrangement of streets in new subdivisions shall
make provisions for the proper projection of streets to adjoining
unsubdivided land, when such land is appropriate for subdivision.

enough to permit resubdivision, or if a portion of the tract is not
subdivided, adequate street right-of-way to permit further subdivision
shall be provided or necessary.
Alleys shall be prohibited in residential districts
except where proved to be necessary.
Streets entering opposite sides of an existing
or a proposed street shall be laid out directly opposite one another.
Where connecting street lines deflect from each
other at any one point by more than 10°, the line must be connected
with a true, circular curve.

of the gross land area is a minimum in relation to the general use
of the facilities to be dedicated for the above categories.
(3) A maximum of 10% of the total land area required by
this section to be provided for recreation may consist of floodplain
areas.
(4) Such land set aside shall be suitable to serve the
purpose of active and/or passive recreation by reason of its size,
shape, location, and topography and shall be subject to the approval
of the Board.
(5) The developer shall satisfy the Board that there are
adequate provisions to ensure retention and all future maintenance
of such recreation areas by maintaining ownership or by providing
for and establishing an organization for the ownership and maintenance
of the recreation area, and such organization shall not be dissolved

the Township without cost to the Township.
(a)
The Township may impose costs to place such
recreation area in appropriate condition prior to accepting dedication.
(b)
All costs of dedication shall be at the expense
of the developer or association who owns the same.
C. Recreation area location criteria. The Planning Commission
and Board (with the assistance of the Recreation Board), in exercising
their duties regarding the approval of subdivision and land development
plans, shall consider the following criteria in determining whether
to approve the proposed location of recreation areas in the developer's
subdivision and land development plans:
(1) The site or sites shall be accessible from all areas
of the development to be served, have good ingress and egress, and
have access to a public road, however, no public road shall traverse
the site or locales.
(2) The site or sites shall have suitable topography and
soil conditions for use and development as a recreation area.
(3) The size and shape of the site or sites shall be suitable
for development as a particular type of park. Sites will be categorized
by the Township using the standards established by the National Recreation
and Parks Association ("Park, Recreation, Open Space and Greenway
Guidelines" dated 1996, as may be amended from time to time).
(4) When designing and developing these recreation areas,
it shall be done according to the standards established by the National
Recreation and Parks Association as modified by the Township recreation
plan.
(5) The site or sites shall, to the greatest extent practical,
be easily accessible to essential utilities, such as water, sewer
and electric.
(6) The site or sites shall meet minimum size requirements
for usable acreage with respect to national Recreation and Parks Association
standards, with 75% of such area having a maximum slope of 7%.
(7) Recreation sites shall be located in a manner which
allows the maximum practical sunlight to neighboring structures.
(8) Where open space is being provided, it shall be located,
wherever possible, to provide a buffer from the shading effects of
taller structures or obstructions on existing or proposed shorter
buildings.
D. Dedication to the Township.
(1) In a case where the developer does not wish to retain
the required recreation area, such area may be offered for dedication
to the Township.
(2) In addition to approving the recreation site areas
to be dedicated to the Township, the Planning Commission shall make
its recommendation to the Board as to whether the dedication shall
be accepted by the Township (including input by the Recreation Board).
(3) Such areas dedicated to the Township for public use
shall be suitable for recreation purposes by reason of size, shape,
location, topography, and access.
(4) The Planning Commission, Recreation Board, or Board
may find dedication to be impractical because of the size, shape,
location, access, topography, drainage, or other physical features
of the land and that such dedication would adversely affect the subdivision
and land development and its future residents or occupants or that
there is no land area within the proposed subdivision which is practical
for dedication to the public because of size, access, topography,
or other physical characteristics.
(5) When the Board deems it to be in the public interest
to accept dedicated land, such acceptance shall be in accordance with
the law.
E. Fee in lieu of dedication.
(1) Where the Board agrees with the developer that because
of the size, shape, location, access, topography, or other physical
features of the land that it is impractical to dedicate land to the
Township or set aside a recreation area as required by this section,
the Board shall agree on a payment of a fee in lieu of dedication
of such land which shall be payable to the Township prior to approval
of each final section of the overall plan by the Township.
(2) The amount of the fee shall be set from time to time
by resolution of the Board.
(3) All monies paid to the Township pursuant to this section
shall be used only for the acquisition of and/or capital improvements
for park and recreation purposes accessible to the development.

receipt by the Township, be deposited in an interest-bearing account,
clearly identifying the specific recreation facilities for which the
fee was received. Interest earned on such accounts shall become funds
of that account. Funds from such accounts shall be expended only in
properly allocable portions of the cost incurred to construct the
specific recreation facilities for which the funds were collected.
(5) Upon request of any person who paid any fee under
this section, the Township shall refund such fee, plus interest accumulated
thereon from the date of payment, if the Township has failed to utilize
the fee paid for the purposes set forth in this section within three
years from the date such fee was paid.
(6) The date upon which the fee is received shall be recorded
in the records of the Township recreation fund and an annual report
of the status of each account and of such proposed facilities as are
funded by each account shall be provided by the Recreation Board at
the February Board meeting to the Commissioners.
(7) Nothing contained herein shall prohibit the person
who paid the fee and the Township from agreeing that the original
recreation facility as proposed by the Township has been superseded
or made unnecessary and reallocating the fee and any interest accumulated
to such other project as the parties agree; provided, however, that
it meets the above standards with regard to a reasonable relationship
to the parcel in question.
(8) All expenditures from fees shall be of interest first
and thereafter principal.
F. Applicability of the Zoning Ordinance. Nothing in this section shall be construed to reduce the total open space requirements of §
325-100 E(3) of the Township of Ridley Zoning Ordinance.
