grading proposed for the subject property, as well as the additional
plan information required in this section.
(2)
All land areas shall be graded to secure proper drainage away
from buildings, on-lot sewage disposal facilities, and the like, and
to prevent the collection of stormwater in pools. Drainage provisions
shall be of such design as to carry surface waters to the nearest
practical natural drainage channel, storm sewer system detention basin
or other drainage facilities. The landowner or developer shall construct
and/or install such drainage structures and/or pipes as are determined
necessary by the Township to prevent soil erosion, damage, siltation
and to satisfactorily carry off surface water. In the design of storm
drainage facilities, special consideration must be given to preventing
excess runoff onto adjacent developed or undeveloped properties. In
no case may any slope exceeding the normal angle of slippage of the
material involved. All slopes must be protected against erosion. In
no case may a change be made in the existing topography which would:
(a)
Result in a slope of more than 10% within 20 feet of a property
line.
(b)
Alter the existing drainage or topography in a way so as to
adversely affect adjoining properties.
(3)
Storm sewers, culverts, bridges, and related drainage installations
shall be provided:

To permit unimpeded flow of natural watercourses.
(b)
To insure adequate drainage of all low points as may be related
to streets.
(c)
To intercept stormwater runoff along streets at intervals reasonably
related to the extent and grade of the area drained to prevent flow
of stormwater across intersections, and to prevent the flooding of
intersections during the design storm.
(d)
To insure adequate and impeded flow of stormwater under driveways
in, near, or across natural watercourses or drainage swales. Properly
sized pipes or other conduits shall be provided as necessary.
(e)

development shall take into account and provide for upstream areas
within the entire watershed in computing discharge quantities, sizing
of pipes, inlets and other structures. The runoff from any proposed
development shall be subject to evaluation which includes the anticipated
runoff from other existing or proposed developments within the same
watershed. Stormwater management facilities designed to serve more
than one property or development in the same watershed are encouraged,
in which case consultation with the Township is required prior to
design.
(5)
All natural streams, channels, swales, drainage systems and/or
areas of concentration of surface water shall be maintained in their
existing condition unless alteration is approved by the Township.
In any event, all encroachment activities shall comply with 25 Pa.Code,
Chapter 105, of the Commonwealth of Pennsylvania Department of Environmental
Protection, "Dam Safety and Waterway Management," rules and regulations.

Any subdivision and/or land development within a flood hazard area shall comply with all of the provisions of the Cumberland Township Zoning Ordinance [Chapter
27], and the rules and regulations of the Pennsylvania Department of Environmental Protection.
(10)
Any water originating from non-natural sources such as swimming
pools, air conditioning units, sump pumps, roof drains or other similar
flow shall not be discharged directly onto any street or other public
right-of-way used for pedestrian or vehicular access. The Township
may require a plan that provides for these discharges.
(11)
All lots, tracts, or parcels shall be graded to provide proper
drainage away from buildings and dispose of the runoff without ponding,
and all land within a development shall be graded to drain and dispose
of surface water without ponding, except where other arrangements
are approved by the Township. Grading shall not be done in such a
way so as to divert water onto the property of another landowner without
the expressed consent of the Township and the affected landowner.
B. Stormwater Management Plan Requirements. In addition to the drainage plan requirements in Part
4 of the Cumberland Township Stormwater Management Ordinance, Ord. 115, 1/3/2006 [Chapter

|
|
Q
|
=
|
Peak discharge in cubic feet per second
|
|
|
C
|
=
|
Runoff coefficient expressed as the ratio of peak runoff rate
to the average amount of rainfall over a period of time equal to the
time of concentration
|
|
|
I
|
=
|
Average rainfall intensity in inches per hour for a time equal
to the time of concentration

undeveloped land shall be considered as "meadow" good condition, unless
the natural ground cover generates a lower runoff curve number (RCN)
or Rational "C" value (e.g., forest).
(c)
Pre-existing pervious or impervious areas, where stormwater
management controls have been previously provided, may be included
as existing conditions in pre-development runoff calculations. However,
if stormwater management controls have not been previously provided,
ground cover shall be considered as meadow.
(d)
Stormwater shall not be re-routed or concentrated in a manner
which is inconsistent with downstream conditions or where downstream
properties are likely to be affected. In addition the proposed stormwater
discharge at the perimeter of the site shall not exceed the capacity
of any existing facility nor shall it alter the pre-development flow
characteristics. All new concentrated discharges of stormwater onto
adjacent properties shall be within existing storm sewers or channels.
The Township may require written acknowledgment or easement from adjacent
property owners in the event that these conditions are not met.
(e)
Cumberland Township has the authority to require that computed
existing runoff rates be reconciled with field observations and conditions.
If the designer can substantiate through actual physical calibration
that more appropriate runoff and time-of-concentration values should
be utilized at a particular site, then appropriate variations may
be made upon review and recommendations of the Cumberland Township
Engineer. Calibration shall require detailed gauge and rainfall data
for the particular site in question.

and where stormwater management has not been previously provided and
it is determined that the proposed development may contribute to the
problem it may be recommended by the Township Engineer that the discharge
of basins or other stormwater management peak flow rate controls be
such that the post-development release rate from storms up to the
ten-year frequency be limited to the pre-development flow rate from
a two-year frequency storm.

A. No subdivision and/or land development application 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 required by this chapter and any walkways, curbs, gutters, street
lights, fire hydrants, shade trees, water mains, sanitary sewers,
storm sewers and other improvements as required by this chapter have
been installed in accordance with this chapter. In lieu of the completion
of any improvements required as a condition for final plan approval,
including improvements or fees required, the developer shall deposit
financial security with the Township in an amount sufficient to cover
the costs of such improvements or common amenities including, but
not limited to, roads, stormwater detention and/or retention basins
and other related drainage facilities, recreational facilities, open
space improvements, or buffer or screen plantings which are or may
be required.
B. When requested by the developer, in order to facilitate financing,
the Board of Supervisors shall furnish the developer with a signed
copy of a resolution indicating approval of the final plan contingent
upon the developer obtaining a satisfactory financial security. The
final plan (record plan) shall not be signed nor recorded until the
financial improvements agreement is executed (where required). The
resolution or letter of contingent approval shall expire and be deemed
to be revoked if the financial security agreement is not executed
within 90 days unless a written extension is granted by the Board
of Supervisors. Such extension shall not be unreasonably withheld
and shall be placed in writing at the request of the landowner or
developer.
2. Completion Guarantee.
A. To satisfy the completion of improvements required as a condition
for the final approval of this chapter as set forth in this chapter,
the landowner or developer shall deposit financial security acceptable
to the Board of Supervisors in an amount sufficient to cover the costs
of such improvements, estimated, calculated and determined as set
forth below.
B. Without limitation as to other types of financial security which
the Township may approve, which approval shall not be unreasonably
withheld, 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.
C. 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 with
the commonwealth.
D. Such bond or other security shall provide for, and secure to the
public, the completion of any improvements, which may be required
on or before the date fixed in the formal action of approval or accompanying
agreement for completion of the improvements.
E. The amount of financial security to be posted the completion of the
required improvements shall be equal to 110% of the cost of completion
estimated as of 90 days following the date scheduled for completion
by the landowner or developer. The Township may adjust the amount
of the financial security annually, 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
of the 90 days after either the original date scheduled for completion
or a rescheduled date of completion. Subsequent to said adjustment,
the Township may require the landowner or developer to post additional
security in order to assure that the financial security equals said
110%. Any additional security shall be posted by the landowner or
developer in accordance with this subsection.
F. The amount of financial security required shall be based upon an
estimate of the cost of completion of the required improvements, submitted
by a landowner 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
the recommendation of the Township Engineer, may refuse to accept
such estimate for good cause shown. If the landowner or developer
and the Township are unable to agree upon an estimate, then the estimate
shall be recalculated and recertified by another engineer licensed
as such in this commonwealth and chosen mutually by the Township and
the landowner 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 services
of said engineer shall be paid equally by the Township and the landowner
or developer.
G. 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 of financial security or to an
amount not exceeding 110% of the cost of completing the required improvements
as reestablished on or about the expiration of the preceding one-year
period by using the above procedure.
H. In the case where development is projected over a period of years,
the Board of Supervisors may authorize submission of final plans by
section or stages of development as it finds essential for the protection
of any finally approved section of the development.
I. As the work of installing the required improvements proceeds, the
party posting the financial security may request the Board of Supervisors
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 requests shall be in
writing addressed to the Board of. Supervisors who shall have 45 days
from receipt of such request within which to allow the Township Engineer
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 Board of Supervisors
shall authorize release by the bonding company or lending institution
of an amount as estimated by the Township Engineer fairly representing
the value of the improvements completed or, if the Board of Supervisors
shall be deemed to have approved the release of funds as requested.
The Board of Supervisors may, prior to final release at the time of
completion and certification by its engineer, require retention of
10% of the estimated cost of the aforesaid improvements.
J. Where the Board of Supervisors accepts dedication of all or some
of the required improvements following completion, the Board may require
the posting of financial security in the form of a maintenance bond
to secure structural integrity improvements of said as well as the
functioning of said improvements in accordance with the design and
specifications as depicted on the final plan 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 in this section
with regard to installation of such improvements, and the amount of
the financial security shall not exceed 15% of the actual cost of
installation of said improvements.
K. If water mains or sanitary sewer lines, or both, along with apparatus
or facilities related thereto, are to be installed under the jurisdiction
and pursuant to the rules and regulations of a public utility or municipal
authority separate and distinct from the Township, financial security
to proper completion and maintenance thereof shall be posted in accordance
with the regulations of the controlling public utility or municipal
authority and shall not be included within the financial security
as otherwise required by this section.
L. If financial security has been provided in lieu of the completion
of improvements required as a condition for the final plan approval,
the Township shall not condition the issuance of building, grading
or other permits relating to the erection or placement of improvements,
including buildings, upon the lots or land as depicted upon the final
plan upon actual completion of the improvements depicted upon the
approved final plan. Moreover, if said financial security has been
provided, occupancy permits for any building of buildings to be erected
shall not be withheld following the improvement of the streets providing
access to and from existing public roads to such building or buildings
to a mud-free or otherwise permanently passable condition, as well
as the completion of all other improvements as depicted upon the approved
final plan, either upon the lot or lots or beyond the lot or lots
in question if such improvements are necessary for the reasonable
use of or occupancy of the building or buildings.
M. Failure to complete any construction or development of the proposed
subdivision or land development within five years following the approval
of a final plan by the Township shall automatically render the approval
of the plat null and void, unless an extension of time has been requested
in writing by the applicant and a written approval granted by the
Cumberland Township Board of Supervisors.
|
Further, failure of the applicant to comply with the requirements
of § 508(4) of the Pennsylvania Municipalities Planning
Code, as amended, 53 P.S. § 10508(4), the contents of which
are also hereby incorporated herein by reference, shall subject the
subdivision or land development to any and all changes in zoning,
subdivision and other governing ordinances enacted by the Township
subsequent to the date of the initial preliminary plan submission.

3. Release from Improvement Bond.
A. When the landowner or developer has completed all of the necessary
and appropriate improvements, the landowner or developer shall notify
the Board of Supervisors, in writing, by certified or registered mail,
of the completion of the aforesaid improvements and shall send a copy
thereof to the Township Engineer. The Board of 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 Board of Supervisors, and shall promptly mail a copy of the
same to the landowner or developer by certified or registered mail.
The report shall be made and mailed within 30 days after receipt by
the Township Engineer of the aforesaid authorization from the Board
of 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, 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 Board of Supervisors shall notify the landowner or developer,
within 15 days of receipt of the Township Engineer's report,
in writing by certified or registered mail of the action of the Board
of Supervisors with relation thereto.
C. If the Board of Supervisors or the Township Engineer fails to comply
with the time limitation provisions contained herein, all improvements
will be deemed to have been approved and the landowner or 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 Board of Supervisors, the landowner or developer
shall proceed to complete the same and, upon completion, the same
procedure of notification, as outlined herein, shall be followed.
E. Nothing herein, however, shall be construed in limitation of the
landowner's or developer's right to contest or question
by legal proceedings or otherwise, any determination of the Board
of Supervisors or the Township Engineer.
F. Where herein reference is made to the Township Engineer, he shall
be a duly registered professional engineer employed by the Township
or engaged as a consultant thereto.
G. The municipality may prescribe that the applicant shall reimburse
the municipality for the reasonable and necessary expense incurred
in connection with the inspection of improvements. The applicant shall
not be required to reimburse the governing body for any inspection
which is duplicative of inspections conducted by other governmental
agencies or public utilities.
|
The burden of proving that any inspection is duplicative shall
be upon the objecting applicant. Such reimbursement shall be based
upon a schedule established by ordinance or resolution. Such expense
shall be reasonable and in accordance with the ordinary and customary
fees charged by the municipality's professional consultant for
work performed for similar services in the community, but in no event
shall the fees exceed the rate or cost charged by the professional
consultant to the municipality for comparable services when fees are
not reimbursed or otherwise imposed on applicants.
|
(1)
The governing body shall submit to the applicant an itemized
bill showing the work performed in connection with the inspection
of improvements performed, identifying the person performing the services
and the time and date spent for each task. In the event the applicant
disputes the amount of any such expense in connection with the inspection
of improvements, the applicant shall, no later than 30 days after
the date of transmittal of a bill for inspection services, notify
the municipality and the municipality's professional consultant,
that such inspection expenses are disputed as unreasonable or unnecessary
and shall explain the basis of their objections to the fees charged,
in which case the municipality shall not delay or disapprove a request
for release of financial security, a subdivision or land development
application or any approval or permit related to development due to
the applicant's dispute of inspection expenses. Failure of the
applicant to dispute a bill within 30 days shall be a waiver of the
applicant's right to arbitration of that bill under this section.
(a)
Subsequent to the final release of financial security for completion
of improvements for a subdivision or land development, or any phase
thereof, the professional consultant shall submit to the governing
body a bill for inspection services, specifically designated as a
final bill. The final bill shall include inspection fees incurred
through the release of financial security.
(2)
If the professional consultant and the applicant cannot agree
on the amount of expenses which are reasonable and necessary, then
the applicant shall have the right, within 45 days of the transmittal
of the final bill or supplement to the final bill to the applicant,
to request the appointment of another professional consultant to serve
as an arbitrator. The applicant and professional consultant whose
fees are being challenged shall by mutual agreement, appoint another
professional consultant to review any bills the applicant has disputed
and which remain unresolved and make a determination as to the amount
thereof which is reasonable and necessary. The arbitrator shall be
of the same profession as the professional consultant whose fees are
being challenged.
(3)
The arbitrator so appointed shall hear such evidence and review
such documentation as the arbitrator in his or her sole opinion deems
necessary and shall render a decision no later than 50 days after
the date of appointment. Based on the decision of the arbitrator,
the applicant or the professional consultant whose fees were challenged
shall be required to pay any amounts necessary to implement the decision
within 60 days. In the event the municipality has paid the professional
consultant an amount in excess of the amount determined to be reasonable
and necessary, the professional consultant shall within 60 days reimburse
the excess payment.
(4)
In the event that the municipality's professional consultant
and applicant cannot agree upon the arbitrator to be appointed within
20 days of the request for appointment of an arbitrator, then, upon
application of either party, the President Judge of the Court of Common
Pleas of the judicial district in which the municipality is located
(or if at the time there be no President Judge, then the senior active
judge then sitting) shall appoint such arbitrator, who, in that case,
shall be neither the municipality's professional consultant nor
any professional consultant who has been retained by, or performed
services for, the municipality or the applicant within the preceding
five years.
(5)
The fee of the arbitrator shall be paid by the applicant if
the review fee charged is sustained by the arbitrator, otherwise it
shall be divided equally between the parties. If the disputed fees
are found to be excessive by more than $5,000, the arbitrator shall
have the discretion to assess the arbitration fee in whole or in part
against either the applicant or the professional consultant. The governing
body and the consultant whose fees are the subject of the dispute
shall be parties to the proceeding.
4. Inspection of Improvements.
A. Construction of all improvements shall be subject to inspection for
conformity with this chapter and the approved plans.
(1)
Construction of all improvements covered by this chapter are
subject to inspection by the Township or its authorized representative.
(2)
Where inspection of improvements is required to determine compliance
with approved plans, the cost and fees for said inspection shall be
paid by the developer in accordance with the fee schedule as adopted
by the Township.
(3)
No person shall interfere with or obstruct the ingress or egress
to or from any such site or premises by an authorized representative
or agent of the Township of Cumberland engaged in the inspection of
work for compliance with the approved plans.
5. As-Built Plan.
A. Upon completion of improvements and approval of same by the Township,
the landowner or developer shall submit to the Board of Supervisors,
a set of as-built plans and profiles in accordance with the requirements
of this chapter. In the event the as-built plan is not submitted in
complete and accurate form, all funds being withheld by means of a
completion guarantee shall not be released, until such plan has been
satisfactorily completed.
B. The as-built plan shall be reproducible and drawn to the same scale
as the final plan, and shall be certified to by an engineer or surveyor
and approved by the Township Engineer.
C. Said plan shall indicate the actual location, dimensions and/or elevations
of all completed improvements including, but not limited to, those
set forth in this chapter.
[Ord. 07-117, 11/13/2007, § 518]
In the event that any improvements which may be required have
not been installed as provided in the subdivision and land development
ordinance, or in accord with the approved final plat, the governing
body of the municipality 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 said security, the governing body
of the municipality may, at 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 improvements covered by such security, and
not for any other municipal purpose.
