the rate and quantity of runoff prior to development (i.e., zero increase
runoff). This standard shall be maintained for all storms (i.e., both
high-frequency and low-frequency).
(b)
Runoff control devices. The increased runoff which may result
from subdivisions and/or land developments shall be controlled by
permanent runoff control measures that will provide the required runoff
control specified above. All runoff control devices will be evaluated
for their effectiveness to maintain the above mentioned standard for
all storms with a return period of up to 100 years.

it would flow, it shall be piped to a stream; provided, however, this
provision shall not apply if the owner of the property which would
be adversely affected by the flow refuses to grant the developer a
right-of-way to pipe the flow from the detention facility underground
at a sufficient depth so as not to interfere with agricultural use
without damage to growing crops and trees and provided further the
pipeline shall be located so as to minimize such surface damage.
(10)
Slope of detention basin embankment.
(a)
The maximum slope of earthen basin embankments shall be four
to one. The top or toe of any slope shall be located a minimum of
15 feet from adjacent property lines with the exception of the downstream

(18)
Positive drainage. Detention basins, not intended as permanent
facilities, must be designed to eliminate standing water or swampy
conditions after the basin has drained. This must be accomplished
either by the installation of stone-trenched underdrains or by providing
a minimum basin bottom slope of 2% to the basin outlet. Other arrangements
may be presented for review and approval by the Township. Normally
dry, open-top storage facilities, designed as such, shall completely
drain both the volume control and rate control capacities over a period
of time not less than 24 hours and not more than 72 hours from the
end of the design storm. However, any designed infiltration volume
at such facilities is exempt from the minimum twenty-four-hour standard,
i.e., may infiltrate in a shorter period of times, so long as none
of the stormwater intended for infiltration is discharged into the
surface waters of the commonwealth.
(19)
Subsurface infiltration/disposal/retention basin systems. The
following procedures and materials shall be required for all subsurface
stormwater management facilities:
(a)

land provided by the utilization of either the land dedication or
the payment of recreation fees provision.
(2)
The amount of land to be dedicated shall continue to be of sufficient
size to provide for necessary parks and recreation facilities or shall
be combined with land already dedicated to the Township for parks
and recreation use on an adjoining parcel.
(3)
The Township Supervisors shall determine, at their discretion, whether
a proposed combination of land dedication and payment of recreation
fees shall be approved.
In a development abutting a lake, river, or other significant
water body, the Board of Supervisors, upon consultation with the Planning
Commission, may request the dedication or reservation of:
On sites reserved for eventual public acquisition as shown on
the Township's Official Map, no building development is permitted
during the period of reservation. Said period of time not to extend
more than 12 months without consent of the developer. Such reservations
shall be noted on the final plan.
A.
No plan shall be finally approved unless the streets shown on such
plan have been improved to a mud-free or otherwise permanently passable
condition, or improved as may be required by this chapter, and any
walkways, curbs, gutters, streetlights, fire hydrants, shade trees,
water mains, sanitary sewers, storm drains and other improvements
required by this chapter have been installed in accordance herewith.
In lieu of the completion of any improvements required as a condition
for the final approval of a plan, the Supervisors shall require, for
deposit with the Township, financial security acceptable to the Supervisors
in an amount sufficient to cover the costs of any improvements or
common amenities, including, but not limited to, roads, stormwater
detention and/or retention basins and other related stormwater management
and drainage facilities, recreational facilities, open space improvements,
or buffer or landscaping plantings which may be required.
B.
Without limitation as to other types of financial security which
the Township may approve, federal or commonwealth chartered lending
institution irrevocable letters of credit and restrictive or escrow
accounts in such lending institutions shall be deemed acceptable financial
security for purposes of this subsection. Such financial security
shall be posted with a bonding company or federal or commonwealth
chartered lending institution chosen by the party posting the financial
security, provided said bonding company or lending institution is
authorized to conduct such business within the commonwealth. Such
bond, or other security, shall provide for, and secure to the public,
the completion of the improvements. In the case where the development
is projected over a period of years, the Supervisors may authorize
submission of the final plans by section or phase of the development
subject to such requirements of guarantees as it finds essential for
the protection of the final approved section of the development.
C.
The amount of financial security to be posted for the completion
of the required improvements shall be equal to 110% of cost of completion
estimated as of 90 days following the date scheduled for completion
by the developer. Annually, the Township may adjust the amount of
the financial security by comparing the actual cost of the improvements
which have been completed and the estimated cost for the completion
of the remaining improvements as of the expiration or the 90th day
after either the original date scheduled for completion or a rescheduled
date of completion. Subsequent to said adjustment, the Township may
require the developer to post additional security in order to assure
that the financial security equals said 110%. Any additional security
shall be posted by the developer in accordance with the subsection.
D.
The amount of financial security required shall be based upon an
estimate of the cost of the completion of the required improvements,
submitted by an applicant or developer and prepared by a professional
engineer licensed as such in this commonwealth and certified by such
engineer to be a fair and reasonable estimate of such cost. The Township,
upon recommendation of the Township Engineer may refuse to accept
such estimate for good cause shown. If the applicant or developer
and the Township are unable to agree upon an estimate, then the estimate
shall be recalculated and recertified by another professional engineer
licensed as such in this commonwealth and chosen mutually by the Township
and the applicant or developer. The estimate certified by the third
engineer shall be presumed fair and reasonable and shall be the final
estimate. In the event that a third engineer is so chosen, fees for
the service of such engineer shall be paid equally by the municipality
and the applicant or developer.
E.
In the event a corporate bond or other financial security has been
offered in lieu of completion of improvements for final plan approval,
the developer shall construct and maintain a passable roadway, along
with any other improvements required for lots which are occupied prior
to acceptance of the roadway and/or other improvements by the Township.
Such maintenance shall continue for the entire bonded period.
F.
If the party posting the financial security requires more than one
year from the date of posting of the financial security to complete
the required improvements the amount of financial security may be
increased by an additional 10% for each one-year period beyond the
first anniversary date from posting the financial security or to an
amount not exceeding 110% of the cost of completing the required improvements
as re-established on or about the expiration of the preceding one-year
period by using the above bidding procedure.
G.
As the work of installing required improvements proceeds, the developer
who has posted the financial security may request the governing body
to release or authorize the release from time to time such portions
of the financial security necessary for payment to the contractor
or contractors performing the work. Any such request shall be in writing
addressed to the Board of Supervisors, and the Board of Supervisors
shall have 45 days from receipt of such request within which to allow
the Township Engineer or other designated inspector to certify, in
writing, to the Board of Supervisors that such portion of the work
upon the improvements has been completed in accordance with the approved
plan. Upon such certification, the Township shall authorize release
by the bonding company or lending institution of an amount as estimated
by the Township Engineer or inspector fairly representing the value
of the improvements completed. The Township may, prior to final release
at the time of completion of said improvements and certification by
its engineer or inspector, require the retention of 10% of the estimated
cost of said improvements.
H.
Where the Board of Supervisors accepts the dedication of all or some
of the required improvements following completion, the Supervisors
may require the posting of financial security to secure structural
integrity of said improvements as well as the functioning of said
improvements in accordance with the design and specifications as depicted
on the final plan and in any related agreements for a term not to
exceed 18 months from the date of acceptance of dedication. Said financial
security shall be of the same type as otherwise required above with
regard to installation of said improvements and the amount of the
financial security shall not exceed 15% of the actual cost of installation
of said improvements.
A.
When the developer has completed all of the necessary and appropriate
improvements, the developer shall notify the Supervisors in writing,
by certified mail, of the completion of the aforesaid improvements
and shall send a copy thereof to the Township Engineer. The Supervisors
shall, within 10 days after receipt of such notice, direct and authorize
the Township Engineer to inspect all of the aforesaid improvements.
The Township Engineer shall, thereupon, file a report, in writing,
with the Supervisors, and shall promptly mail a copy of the same to
the developer by certified or registered mail. The report shall be
made and mailed within 30 days after the receipt by the Township Engineer
of the aforesaid authorization by the Supervisors; said report shall
be detailed and shall indicate approval or rejection of said improvements,
either in whole or in part, and if said improvements, or any portion
thereof, shall not be approved or shall be rejected by the Township
Engineer, said report shall contain a statement of reasons for such
nonapproval or rejection.
B.
The Supervisors shall notify the developer, within 15 days of receipt
of the Township Engineer's report, in writing by certified or registered
mail, of the action of the Supervisors with relation thereto.
C.
If the Supervisors or Township Engineer fails to comply with the
time limit contained herein, all improvements shall be deemed to have
been approved and the developer shall be released from all liability,
pursuant to its performance guaranty bond or other security agreement.
D.
If any portion of the said improvements shall not be approved or
shall be rejected by the Supervisors, the developer shall proceed
to complete the same and upon completion, the same procedure of notification,
as outlined in this chapter, shall be followed.
E.
Nothing in this chapter, however, shall be construed in limitation
of the developer's right to contest or question by legal proceedings
or otherwise, any determination of the Supervisors or the Township
Engineer.
F.
Where reference is made in this chapter to Township Engineer, he
shall be a duly registered professional engineer employed by the Township
or engaged as a consultant to the Township.
In the event that any improvements which are required have not
been installed as provided in this chapter or in accord with the approved
final plan, the Township is hereby granted the power to enforce any
corporate bond or other security by appropriate legal and equitable
remedies. If proceeds of such bond, or other security are insufficient
to pay the cost of installing or making repairs or corrections to
all the improvements covered by such security, the Township may, as
its option, install part of such improvements in all or part of the
subdivision or land development and may institute appropriate legal
or equitable action to recover the moneys necessary to complete the
remainder of the improvements. All of the proceeds, whether resulting
from the security or from any legal or equitable action brought against
the developer, or both, shall be used solely for the installation
of the improvements covered by such security, and not for any other
Township purpose.
Upon installation by the developer and subsequent inspection
by the Township Engineer, the developer shall take final steps to
dedicate the improvements and have them accepted by the Township.
The recording of the final plan, following approval by the Board of
Supervisors, has the effect of an irrevocable offer to dedicate all
streets and other public ways and areas to public use. The offer,
however, does not impose any duty whatsoever on the Township to accept
dedication of any improvements to the Township concerning maintenance
or improvements until the proper authorities of the Township have
made actual acceptance, either by ordinance or resolution.
All applicants proposing any subdivision and/or land development
requiring the installation of improvements as required by this chapter
shall, prior to final plan approval by the Board of Supervisors, and
if so directed, enter into a legally binding development agreement
with the Township whereby the developer guarantees the installation
of the required improvements in accord with the approved plan and
all applicable Township requirements.
