A.
The purpose of this article is to establish and define the public
improvements which will be required by New Britain Borough Council
to be constructed or caused to be constructed by the applicant. Inspection
of improvements will be the responsibility of the New Britain Borough
Engineer.
B.
All improvements will be constructed in accordance with the specifications
of New Britain Borough and this chapter.
A.
The improvements required by this chapter are minimum requirements.
New Britain Borough reserves the right in any case to increase the
same if conditions so warrant in order to protect the health, safety
and welfare of Borough residents.
B.
Before the Borough Council shall cause its approval to be endorsed
on the final plans of any subdivision or land development and as a
requirement for the approval thereof, the developer shall enter into
a written agreement with the Borough, in the manner and form set forth
by the Borough Solicitor to guarantee the construction and installation
of all improvements at the developer's expense as required by this
chapter. When requested by the developer in order to facilitate financing,
the Borough Council shall furnish the developer with a signed copy
of a resolution indicating approval of the final plan contingent upon
the developer obtaining satisfactory financial security. The final
plan or record plan shall not be signed nor recorded until the financial
improvements agreement is executed. 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 Borough Council.
C.
No plan shall receive final approval unless the streets shown have
been improved to a permanently passable condition, or improved as
may be required by this chapter, and any walkways, bikeways, curbs,
gutters, streetlights, fire hydrants, shade trees, water mains, sanitary
sewers, storm drains and other improvements as may be required by
this chapter have been installed. In lieu of the completion of any
improvements, the developer shall furnish to the Borough a bond with
such surety as the Borough Council shall approve, in an amount sufficient
to cover the costs of any improvements which may be required. 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 improvements. The amount of financial security to
be posted for completion of the required improvements shall be equal
to 110% of the cost of completion estimated as of 90 days following
the date of scheduled completion by the developer. Annually, the Borough
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
of the 90th day after either the original date scheduled for completion
or a rescheduled date of completion. Subsequent to said adjustment,
the Borough 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 this section.
D.
The amount of financial security required shall be based upon an estimate of the cost of completion of the required improvements submitted by an applicant and prepared by a professional engineer licensed as such in the Commonwealth of Pennsylvania and certified by such engineer to be a fair and reasonable estimate of such cost. The Borough, upon recommendation of the Borough Engineer, may refuse to accept such estimate for good cause shown. If the applicant or developer and the Borough are unable to agree upon an estimate, the procedures set forth in the Pennsylvania Municipalities Planning Code, Article V, Section 509(g) shall be followed. If the developer 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 bidding procedure.
E.
In the case where development is projected over a period of years,
the Borough Council may authorize submission of final plans by section
or stages of development, subject to such requirements or guarantees
as to improvements in future stages of development as it finds essential
for the protection of any finally approved section of the development.
As the work of installing the required improvements proceeds, the
developer may request the Borough to release, from time to time, portions
of the escrow fund necessary for payment to the contractor performing
the work. Any such request shall be in writing addressed to the Borough
Council, and the Council shall have 45 days from receipt of such request
within which to allow the Borough Engineer to certify, in writing,
to the Council that the improvements have been completed in accordance
with the approved plan. If the Borough Council fails to act within
the forty-five-day period, the Council shall be deemed to have approved
the release of funds as requested. The Council may, prior to final
release at the time of completion and certification by the Borough
Engineer, require retention of 10% of the estimated cost of the aforesaid
improvements.
F.
Where the Borough accepts dedication of all or some of the required
improvements following completion, the Borough may require the posting
of financial security to secure structural integrity of the 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. The amount of this financial security shall not exceed
15% of the actual cost of installation of the improvements.
G.
If financial security has been provided in lieu of the completion
of improvements required as a condition for the final approval of
a plan as set forth in this section, the Borough shall not condition
the issuance of building, grading or other permits relating to the
construction of the improvement, including buildings, upon lots or
land as depicted upon the final plan. Moreover, if an escrow fund
has been established, occupancy permits for any building or 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 permanently passable condition as well
as the completion of all other improvements as depicted upon the approved
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.
H.
Release from improvement bond.
(1)
When the developer has completed all of the necessary and appropriate
improvements, submitted as-built plans, and the as-built plans have
been approved by the Borough Engineer, the developer shall notify
the Borough by certified or registered mail of the completion of the
improvements and shall send a copy to the Borough Engineer. The Borough
shall, within 10 days after receipt of such notice, direct and authorize
the Borough Engineer to inspect all of the improvements. The Borough
Engineer shall file a report with the Borough and shall mail a copy
of the report to the developer. The report shall be made within 30
days after receipt by the Borough Engineer of the authorization from
the Borough. This report shall indicate approval or rejection of the
improvements; and if the improvements or any portion thereof shall
not be approved by the Borough Engineer, this report shall contain
a statement of reasons for such nonapproval.
[Amended 5-8-2018 by Ord.
No. 387]
(2)
The Borough shall notify the developer, within 15 days of receipt
of the Engineer's report, in writing by certified or registered mail,
of its actions in response to the Borough Engineer's review of improvements.
(3)
If the Borough or the Borough Engineer fails to comply within the
time limitation provisions, all improvements will be deemed to have
been approved, and the developer shall be released from all liability
pursuant to its performance guarantee bond or other security agreement.
(4)
If any portion of the improvements shall not be approved or shall
be rejected by the Borough, the developer shall proceed to complete
the improvements and, upon completion, the same procedure of notification,
as outlined, shall be followed.
(5)
The applicant shall reimburse the Borough for the reasonable and necessary expense incurred for the inspection of such improvements. Such reimbursement shall be based upon a schedule adopted by resolution and shall be reasonable and in accordance with the ordinary and customary fees charged by the Borough Engineer or consultant for work performed for similar services in the Borough, and in no event shall the fees exceed the rate or cost charged by the Borough Engineer or consultant to the Borough when fees are not reimbursed or otherwise imposed on applicants. In the event that the applicant disputes the amount of such expense in connection with inspection of improvements, the procedure set forth in the Pennsylvania Municipalities Planning Code (Act 247, as amended), Section 510(g), subsections (1) through (5), shall be adhered to.[1]
[1]
Editor's Note: See 53 P.S. § 10510(g)(1) through
(5).
I.
Remedies for completion of improvements. In the event that any improvements
which may be required have not been installed as provided in this
chapter or in accord with the approved final plan, the Borough shall
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 to
all the improvements covered by the security, the Borough 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 the improvements covered by such security and not for any other
Borough purposes.
A.
The construction of streets, roads, lanes and driveways as shown
upon final plans and as contained in contract agreements shall in
every respect conform to such requirements as New Britain Borough
may by this chapter or other resolution require for the construction
of streets.
B.

A.
General.
(1)
The applicant shall construct or install such drainage structures,
on site and off site, as necessary to:
(a)
Prevent erosion damage and to satisfactorily carry off or detain
and control the rate of release of surface waters.
(b)
Encourage all runoff-control measures to percolate the stormwater
into the ground to aid in the recharge of groundwater.
(c)
Carry surface water to the nearest adequate street, storm drain,
stormwater BMP, natural watercourse, or drainage facility.
(d)
Take surface water from the bottom of vertical grades, to lead
water away from springs, and to avoid excessive use of cross gutters
at street intersections and elsewhere.
(e)
Handle the anticipated peak discharge from the property being
subdivided or developed and the existing runoff being contributed
from all land at a higher elevation in the same watershed.
(f)
Maintain the adequacy of the natural stream channels. Accelerated
bank erosion shall be prevented by controlling the rate and velocity
of runoff discharge to these watercourses so as to avoid increasing
the occurrence of streambank overflow.
(g)
Preserve the adequacy of existing culverts. Bridges and similar
structures shall be preserved by suppressing the new flood peaks created
by new alteration or development of land.
(2)
Drainage area boundary plans shall be submitted, reviewed, and approved
for all structures, stormwater BMPs, and collection devices.
(3)
Additional studies and higher levels of control than the minimum
provided in these and other New Britain Borough requirements and criteria
may be required by the Borough Council to ensure adequate protection
to life and property.
(4)
If special geological hazards or soil conditions, such as carbonate
derived soils, are identified on the site, the applicant's engineer
shall consider the effect of proposed stormwater management measures
on these conditions. In such cases, the Borough may require an in-depth
report by a qualified soils engineer.
B.
Retention of existing watercourses and natural drainage features.
(1)

within a development site, it shall remain open in its natural state
and location and shall not be piped.
(2)
The existing points of natural discharge onto adjacent property shall
not be altered without the written approval by the affected landowners.
(3)
No stormwater runoff or natural drainage shall be so diverted as
to overload existing drainage systems or create flooding or the need
for additional drainage structures on private properties or public
lands.
C.
All subdivisions and land developments are subject, in addition, to the requirements of Chapter 375, Stormwater Management, of the Code of the Borough of New Britain, which is included in these regulations by reference.
D.
Stormwater runoff which may result from alteration or development of land shall be controlled by permanent stormwater runoff BMPs that will provide the required standards within this section, Chapter 375, and any other requirements of New Britain Borough.

berm is protected against erosion.
(d)
The emergency spillway shall not discharge over earthen fill
and/or easily eroded material.
(e)
The construction material of the emergency spillways shall extend
along the upstream and downstream berm embankment slopes. The upstream
edge of the emergency spillway shall be a minimum of three feet below
the spillway crest elevation. The downstream slope of the spillway
shall, at a minimum, extend to the toe of the berm embankment.
(f)
The minimum capacity of all emergency spillways shall be the
peak flow rate from the post-development 100-year design storm.
(g)

B.
All public sanitary sewers shall be designed and constructed in accordance with the standard specifications of the Authority and in accordance with such other terms and conditions as may be set forth in the agreement mentioned in Subsection A above.
C.
No public sanitary sewer line or connection shall be constructed
until plans and specifications have been submitted to the Pennsylvania
Department of Environmental Protection, the Bucks County Department
of Health, the Bucks County Planning Commission, and any other agency
having jurisdiction.
D.
No final plan shall be approved without certification that the sewage
to be generated by the proposed subdivision or land development can

E.
Temporary holding tanks.
[Added 9-13-2005 by Ord. No. 302]
(1)
Under the circumstances set forth below, New Britain Borough will
permit the installation and maintenance of sanitary sewer holding
tanks on a temporary basis, until public conveyance and treatment
of wastewater is available to an applicant for a specific parcel of
land, where the PADEP and Bucks County Department of Health (BCDH)
permits holding tanks.
(2)
An applicant for a holding tank permit shall file an application
on a form approved by the Borough for a holding tank permit along
with the fee established pursuant to the Borough fee schedule in effect
at the time of application. The application shall include complete
plans specifying all design criteria, including but not limited to
design drawings and calculations, pump specifications, wet well and
alarm specifications, and any other data required by the Borough Engineer,
and shall include as well any other permits required by PADEP, BCDH
and current New Britain Borough ordinances (at the time of application).
The application shall also include a written statement from the future
downstream sanitary sewer service conveyance and treatment providers,
indicating when public sanitary sewer capacity will be available.
(3)
Holding tank designs shall be permitted when no other feasible method to obtain sanitary sewage disposal is immediately available due to lack of downstream conveyance and/or treatment capacity. On-lot septic disposal shall be considered and utilized first, if possible (see Subsection F of this section). If on-lot septic disposal is not possible, all documentation proving such shall be submitted for review prior to consideration of a holding tank. Holding tanks shall be located a minimum of 50 feet from property lines and shall be provided with suitable access. Holding tank design and construction shall be consistent with PADEP rules and regulations of 25 Pa. Code § 73.62, "Standards for holding tanks."
(4)
A holding tank is a watertight, sealed vessel to be utilized for temporary storage of sanitary sewage waste. Temporary use is defined to require that the vessel shall be emptied by pumping on a regular basis (weekly, monthly or other approved interval) and also requires that the tank shall only be permitted to be utilized for a period of up to one year from the date of connection. An applicant may apply to extend the life of the permit beyond the one-year period by filing an application for extension, filed prior to the expiration of the then current permit. The Borough shall approve any such permit extension application, provided that the extension is necessitated by the continued inadequacy of downstream conveyance and treatment capacity. To the extent that any extension is sought based upon the failure of or inability of the applicant to timely connect to available public sewer, then that application shall be denied. The application for extension shall be accompanied by the agencies listed in Subsection E(2) above. Upon expiration of any permit, the holding tank facility shall not be used, and the facility shall be abandoned and removed. Any permit issued hereunder authorizing the maintenance of a sanitary sewer holding tank shall expire 90 days after a determination by the Borough that public sanitary facilities are available to the affected parcel of land. Upon a determination by the Borough that sanitary sewer facilities are available to a parcel utilizing permitted holding tank facilities, the applicant shall be required to obtain all necessary permits and to pay all fees for connection to the public sanitary sewer system prior to expiration of the ninety-day time period after public sanitary sewer facilities have been determined to be available by the Borough. All holding tank facilities shall be abandoned and removed completely prior to the expiration of the said ninety-day period.
(5)
No permit shall issue for the installation and maintenance of a holding
tank facility unless the applicant shall have executed an agreement
with the Borough establishing maintenance standards, sewage (septage)
disposal facility location [per requirements of 25 Pa. Code § 73.62(d)],
and a future connection and a pumping schedule. The agreement shall
require that the applicant shall provide the Borough with an executed
copy of a maintenance and pumping contract for the facility and shall
require that the applicant provide maintenance and pumping records
to the Borough on a monthly basis (or other appropriate time interval
agreed to by the Borough) and be accompanied by an approved bond or
cash escrow with the Borough to guarantee the pumping and maintenance
schedule as well as for permit review and periodic inspections. In
addition, the applicant shall provide an approved bond or escrow deposit
to guarantee the operation, abandonment and removal of the holding
tank facility, as well as a cash permit fee to pay Borough expenses
for administrative costs. All escrows and fee amounts shall be in
accordance with the current New Britain Borough Schedule of Fees.
In the event of any facility malfunction or notice to correct from
the Borough Inspector or Engineer, the applicant shall immediately
effect any necessary repairs or corrections and, in default thereof,
the Borough may apply applicant's bond or escrowed funds to address
any malfunction or make any needed corrections to the facility. Should
any of the required bonds or escrow amounts be depleted by as much
as 50%, the applicant shall post an additional amount sufficient to
restore the full amount of the escrow or bond required pursuant to
this paragraph. The agreement shall require that any applicant shall
defend, indemnify and hold harmless the Borough and any other agencies
having jurisdiction over the facilities from any and all costs, losses,
expenses or other liability arising from the design, installation
or maintenance of any holding tank facility; and, further, the applicant
shall release the Borough and any agencies having jurisdiction over
the facilities of any liability for losses or projected losses resulting
from any order to abandon the facilities before conventional sewerage
facilities are available to the applicant.[1]

[Added 9-13-2005 by Ord. No. 302]
(1)
Under the circumstances set forth below, New Britain Borough will
permit the installation and maintenance of sanitary sewer on-lot septic
systems on a temporary basis, until public conveyance and treatment
of wastewater is available to an applicant for a specific parcel of
land, where the PADEP and BCDH permits holding tanks.
(2)
An applicant for an on-lot septic system shall file an application
on a form approved by the Borough for a septic system permit along
with the fee established pursuant to the Borough Fee Schedule in effect
at the time of application. The application shall include complete

time of application). The application shall also include a written
statement from the future downstream sanitary sewer service conveyance
and treatment providers, indicating when public sanitary sewer capacity
will be available.
(3)
On-lot septic systems shall be permitted when there is no sanitary
sewage disposal method immediately available due to lack of downstream
conveyance and/or treatment capacity. On-lot septic system location,
design, and construction shall be consistent with PADEP rules and
regulations at 25 Pa. Code Chapter 73, Standards for On-lot Sewage
Treatment Facilities.
(4)
An on-site septic system may be a conventional, elevated sand mound, A-B, or drip system to be utilized for temporary disposal of sanitary sewage waste. Temporary use is defined to require that the system shall only be permitted to be utilized for a period of up to one year from the date of connection. An applicant may apply to extend the life of the permit beyond the one-year period by filing an application for extension, filed prior to the expiration of the then current permit. The Borough shall approve any such permit extension application, provided that the extension is necessitated by the continued inadequacy of downstream conveyance and treatment capacity. To the extent that any extension is sought based upon the failure of or inability of the applicant to timely connect to available public sewer, then that application shall be denied. The application for extension shall be accompanied by the agencies listed in Subsection F(2) above. Upon expiration of any permit, the septic system shall not be used, and the facility shall be abandoned and removed. Any permit issued hereunder authorizing the maintenance of an on-lot septic system shall expire 90 days after a determination by the Borough that public sanitary facilities are available to the affected parcel of land. Upon a determination by the Borough that sanitary sewer facilities are available to a parcel utilizing a permitted septic system, the applicant shall be required to obtain all necessary permits and to pay all fees for connection to the public sanitary sewer system prior to expiration of the ninety-day time period after public sanitary sewer facilities have been determined to be available by the Borough. All holding tank facilities shall be abandoned and removed completely prior to the expiration of the said ninety-day period.
(5)
No permit shall issue for the installation of an on-lot septic system
unless the applicant shall have executed an agreement with the Borough
establishing maintenance standards and a future connection schedule.
The agreement shall require that the applicant shall provide the Borough
with an executed copy of a maintenance contract for the system and
be accompanied by an approved bond or cash escrow with the Borough
to guarantee the maintenance standards as well as for permit review
and periodic inspections. In addition, the applicant shall provide
an approved bond or escrow deposit to guarantee the operation, abandonment
and removal of the system, as well as a cash permit fee to pay Borough
expenses for administrative costs. All escrows and fee amounts shall
be in accordance with the current New Britain Borough Schedule of
Fees. In the event of any system malfunction or notice to correct
from the Borough Inspector or Engineer, the applicant shall immediately
effect any necessary repairs or corrections and, in default thereof,
the Borough may apply the applicant's bond or escrowed funds to address
any malfunction or make any needed corrections to the facility. Should
any of the required bonds or escrow amounts be depleted by as much
as 50%, the applicant shall post an additional amount sufficient to
restore the full amount of the escrow or bond required pursuant to
this paragraph. The agreement shall require that any applicant shall
defend, indemnify and hold harmless the Borough and any other agencies
having jurisdiction over the facilities from any and all costs, losses,
expenses or other liability arising from the design, installation
or maintenance of any holding tank facility; and, further, the applicant
shall release the Borough and any agencies having jurisdiction over
the facilities of any liability for losses or projected losses resulting
from any order to abandon the facilities before conventional public
sewerage facilities are available to the applicant.[2]
