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]

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.

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 plans specifying all design criteria, including but not limited to design drawings and calculations, pump specifications, wet well and alarm specifications and any other applicable 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) 
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]
