All storm drainage facilities shall be inspected and approved by the Borough Engineer prior to being covered.
C. 
Erosion control. When topsoil has been removed from the surface of a lot on a slope where erosion will cause a displacement of loose material, the subdivider is required to seed or provide other means to prevent the wash from damaging adjacent property, accumulating on surfaces of lower streets and clogging of sewers, as well as the silting of streams. Where the physical condition of the site may cause surface water to pond, the disposition of all such water shall be shown on the preliminary plan. During construction phases, any diversion of surface water must be inspected and approved by the Borough Engineer. During final grading of property, if groundwater is discovered, such water must be channeled through approved piping to storm sewer systems.

All construction materials used in sewers and appurtenances, streets and sidewalks shall be tested by a qualified testing laboratory as may be directed by the Borough Engineer. The cost for such tests shall be borne by the developer.
If Council, upon the advice of the Planning Commission, determines that the application of the standards set forth in § 300-51B would result in an open space or public recreation site too small to be usable, or if the community development objectives (see § 420-3) indicate that such public recreation site should be located elsewhere, or if a suitable public recreation site cannot be properly located in the proposed development, the payment of a fee in lieu of the dedication of such land shall be required in accordance with the following procedure:
A. 
The amount of the fee shall be substantially equal to the value of the land that would be set aside if the standards specified in § 300-51B were applied.
B. 
The fee shall be paid to the Borough prior to the approval of the final plat.
C. 
All fees paid to the Borough under this section shall be deposited in a special escrow fund to be used for acquisition and development of park and recreational facilities. Moneys spent may be expended on neighborhood or community facilities in reasonable proximity to the subdivision.
Where on-site and off-site public improvements are involved and/or approved, the developer, before approval of the final plat, shall execute a development agreement containing provisions that are reasonably required, in the opinion of the Solicitor, to guarantee the construction and installation of the required improvements in accordance with this chapter and/or any other ordinance, standard, rule or regulation of the Borough, which development agreement shall contain appropriate provisions providing for the indemnification of the Borough in connection therewith.
Subject to the provisions of § 300-56, no plat shall be finally approved unless the streets shown on such plat have been improved as may be required by this chapter and unless all walkways, 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 accordance with the same.
A. 
In lieu of the completion of any improvement required as a condition for the final approval of a plat, the applicant shall deposit with the Borough a corporate bond or other financial security, acceptable to Council, in an amount sufficient to cover the costs of any improvement which may be required, which financial security may include, inter alia, a lending institution letter of credit or a restrictive or escrow account in a lending institution.
B. 
Such bond or other security shall provide for and secure to the Borough the completion of any improvement which may be required within one year of the date fixed in the development agreement for the completion of such improvement.
C. 
Where development is projected over a period of years, Council may authorize the submission of final plats by sections or stages of development, subject to such requirements or guarantees as to improvements in future sections or stages of development as Council finds essential for the protection of any finally approved section of the development.
D. 
All such bonds or other security shall be in favor of the Borough, and all sureties in connection with any guarantee or bond shall be on the approved list of the Pennsylvania Insurance Commission.
E. 
The amount of the bond or other security shall be based on estimates by a registered engineer or a reputable contractor, but only after approval by the Borough Engineer.
F. 
Such bond or other security shall remain in force and terminate in accordance with Section 510 of Act 247, as amended,[1] but in all cases the bond shall be forfeited if the work is not completed within one year after the date for completion as set forth in the development agreement.

Editor's Note: See 53 P.S. § 10510.
If the Borough Engineer deems that the construction of the development could cause damage to or failure of existing Borough streets, sewers or other facilities and/or utilities, the applicant shall furnish a special maintenance bond in an amount fixed by the Borough Engineer to guarantee repairs or replacements. However, the terms of the special maintenance bond shall be in full conformity with § 300-56.
Upon completion of the required improvements and installations, the applicant shall provide a three-year maintenance bond, which shall:
A. 
Be in favor of the Borough and provide a surety which is on the approved list of the Pennsylvania Insurance Commission;
B. 
Be in an amount equal to 50% of the amount of the improvement bond; and
C. 
Provide that, for three years after the completion of such improvements and installations, the subdivider, developer or his or her surety will, at his or her own expense, make all repairs of such improvements and installations which may become necessary by reason of improper workmanship, faulty materials or damage occurring during construction. Prior to, and as a condition of, the final plat approval, a written commitment by the subdivider shall be submitted to the office of the Manager stating the willingness on the part of the subdivider or developer to comply with this subsection at the time of completion of the construction. Roadway maintenance bonds are also for three years.
As an alternative to the posting of the required bonds or other security, the developer may deposit a cash guarantee in the form of a certified or cashier's check or an escrow account with terms satisfactory to Council. All funds deposited for guaranteeing construction shall be used only for the purpose of making improvements, installations or repairs for which the bond or cash was provided. Based on the progress of the work, percentages of the deposit shall be returned to the developer on a monthly basis. Such progress and returned deposits shall be certified by the Manager.
After the required roads, streets, sewers and other improvements have been installed and constructed pursuant to this chapter, and if a developer then wishes to have the Borough accept such roads, streets, sewers and other improvements as a part of the Borough system, then the developer shall notify the Borough Engineer that the construction or installation has been completed and shall supply the Borough with a tracing of the plan of lots or development in question as built in accordance with the final approval thereof. Such tracing shall be certified by a registered engineer. The developer shall also supply the Borough with a minimum of four copies of the as-built plan on the basis of which the roads, streets, sewers and other improvements in question have been constructed or installed. Such tracing and four copies of the plan shall be confirmed copies in every respect and contain a notice thereon as to where and when the plan was recorded in the office of the County Recorder of Deeds.
With respect to the portions of roads, streets, sewers or other improvements which the developer wishes to have the Borough accept, the developer shall shade or color such portions in yellow crayon on each of the copies required by § 300-60 and shall also clearly designate the number of linear feet of such roads, streets, sewers or other improvements which he or she wishes to be accepted by the Borough. The maintenance bond required by § 300-58 shall be furnished to the Borough contemporaneously with such plan. The maintenance bond shall contain an accurate, well-defined description of the portions of such roads, streets, sewers or other improvements which the developer wishes the Borough to accept.
The developer shall submit a formal petition for the acceptance of improvements. In addition, a legal description of the center line (or perimeter) of each street or road and each storm or sanitary sewer easement shall be furnished for inclusion in the ordinance of acceptance. Such petition shall contain appropriate provisions which, in the opinion of the Solicitor, are sufficient to release the Borough from any and all liability, damages, claims and expenses for damages, direct or consequential, sustained or allegedly sustained by the applicant or his or her heirs, successors or assigns in connection with or as a result of the acceptance of any public improvement or the establishment or change in any grade of any street or road and in connection with the repair, replacement, maintenance or removal of any public improvement, facility or utility, including, but not limited to, any storm or sanitary sewer.
