C. 
All new or replacement water systems located in flood-prone areas, whether public or private, shall be floodproofed to a point one foot above the base flood elevation.
All other new or replacement public and/or private utilities and facilities in flood-prone areas shall elevated or floodproofed to a point one foot above the base flood elevation.
Whenever the evidence available to the Board of Commissioners indicates that natural surface drainage is inadequate, the developer shall install a stormwater sewer system in accordance with approved plans and profiles. The system shall be designed by a registered engineer and be approved by the Township Engineer.
A. 
Fire hydrants shall be installed if their water supply source is capable to serve them in accordance with the requirements of the local fire authority.
B. 
Fire hydrants, if provided, shall be located within 600 feet of any dwelling unit or structure open to the public. Fire hydrants shall be installed in accordance with all applicable regulations.
A. 
No plat shall be finally approved unless the streets shown on such plat have been improved to a mud-free or otherwise permanently passable condition, or improved as may be otherwise required by this chapter, and any walkways, curbs, gutters, streetlights, fire hydrants, shade trees, water mains, sanitary sewers, storm sewers and other improvements as may be 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 the final approval of a plat, including improvements or fees otherwise required by this chapter, the developer may deposit with the Township financial security in an amount sufficient to cover the costs of such improvements or common amenities, including basins and other related drainage facilities, recreational facilities, open-space improvements, or buffer or screen plantings which may be required.
B. 
When requested by the developer, in order to facilitate financing, the Board of Commissioners shall furnish the developer with a signed copy of a resolution indicating approval of the final plat contingent upon the developer obtaining a satisfactory financial security. The final plat 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 Board of Commissioners; such extension shall not be unreasonably withheld and shall be placed in writing at the request of the developer.
C. 
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 for the purposes of this section.
D. 
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.
E. 
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.
F. 
The amount of financial security to be posted for 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 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 of 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 this subsection.
G. 
The amount of financial security required shall be based upon an estimate of the cost of completion of the required improvements submitted by the 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 the 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 services of said engineer shall be paid equally by the Township and the applicant or developer.
H. 
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 bidding procedure.
I. 
In the case where development is projected over a period of years, the Board of Commissioners may authorize 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 it finds essential for the protection of any finally approved section of the development.
J. 
As the work of installing the required improvements proceeds, the party posting the financial security may request the Board of Commissioners to release or authorize the release from time to time of 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 Commissioners, and the Board of Commissioners shall have 45 days from receipt of such request within which to allow the Township Engineer to certify, in writing, to the Board of Commissioners that such portion of the work upon the improvements has been completed in accordance with the approved plat. Upon such certification, the Board of Commissioners 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 Commissioners fails to act within said forty-five-day period, the Board of Commissioners shall be deemed to have approved the release of funds as requested. The Board of Commissioners 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.
K. 
Where the Board of Commissioners accepts dedication of all or some of the required improvements following completion, the Board of Commissioners 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 plat 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.
L. 
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 assure 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.
M. 
If financial security has been provided in lieu of the completion of improvements required as a condition for the final approval of a plat as set forth in this section, 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 plat upon actual completion of the improvements depicted upon the approved final plat. Moreover, if said financial security has been provided, 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 mud-free or otherwise permanently passable condition, as well as the completion of all other improvements as depicted upon the approved plat, 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.
A. 
When the developer has completed all of the necessary and appropriate improvements, the developer shall notify the Board of Commissioners, 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 Commissioners 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 Commissioners 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 receipt by the Township Engineer of the aforesaid authorization from the Board of Commissioners; 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 Board of Commissioners shall notify the developer, within 15 days of receipt of the Engineer's report, in writing by certified or registered mail, of the action of said Board of Commissioners with relation thereto.
C. 
If the Board of Commissioners 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 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 Commissioners, the 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 developer's right to contest or question by legal proceedings or otherwise any determination of the Board of Commissioners or the Township Engineer.
F. 
Where herein reference is made to the Township Engineer, he shall be as a consultant thereto.
G. 
The applicant or developer shall reimburse the Township for the reasonable and necessary expense incurred for the inspection of improvements according to a schedule of fees adopted by resolution of the Board of Commissioners and as from time to time amended. Such expense shall be reasonable and in accordance with the ordinary and customary fees charged by the Township Engineer or 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 Engineer or consultant to the Township when fees are not reimbursed or otherwise imposed on applicants.
(1) 
In the event the applicant disputes the amount of any such expense in connection with the inspection of improvements, the applicant shall, within 10 working days of the date of billing, notify the Township that such expenses are disputed as unreasonable or unnecessary, in which case the Township shall not delay or disapprove a subdivision or land development application or any approval or permit related to development due to the applicant's request over disputed Engineer expenses.
(2) 
If within 20 days from the date of billing the Township and the applicant cannot agree on the amount of expenses which are reasonable and necessary, then the applicant and the Township shall jointly, by mutual agreement, appoint another professional engineer licensed as such in the Commonwealth of Pennsylvania to review the said expenses and make a determination as to the amount thereof which is reasonable and necessary.
(3) 
The professional engineer so appointed shall hear such evidence and review such documentation as the professional engineer in his or her sole opinion deems necessary and render a decision within 50 days of the billing date. The applicant shall be required to pay the entire amount determined in the decision immediately.
(4) 
In the event that the Township and applicant cannot agree upon the professional engineer to be appointed within 20 days of the billing date, then, upon application of either party, the President Judge of the Court of Common Pleas of the judicial district in which the Township is located (or if at the time there be no President Judge, then the senior active judge then sitting) shall appoint such engineer, who in that case shall be neither the Township Engineer nor any professional engineer who has been retained by or performed services for the Township or the applicant within the preceding five years.
(5) 
The fee of the appointed professional engineer for determining the reasonable and necessary expenses shall be paid by the applicant if the amount of payment required in the decision is equal to or greater than the original bill. If the amount of payment required in the decision is less than the original bill by $1,000 or more, the Township shall pay the fee of the professional engineer, but otherwise the Township and the applicant shall each pay 1/2 of the fee of the appointed professional engineer.
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 plat, the Board of Commissioners is hereby granted the power to enforce any corporate bond or other security by appropriate legal and equitable remedies. If the 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 Board of Commissioners 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 Township purpose.
The offer to dedicate streets, parks or other areas or portions of them does not impose any duty upon the Township concerning maintenance or improvement until the proper authorities of the Township have made actual appropriation by ordinance or resolution or by entry or improvement. If land is dedicated for a public site and its use for this purpose is not imminent, the developer may be permitted to dedicate the land with the privilege of using the surface rights until the Township is ready to use the land. Such dedication with the temporary privilege of use must be noted on the final plan.
On sites reserved for eventual public acquisition, no building development is permitted during the period of reservation, said period of time not to extend more than 18 months, without consent of the developer. Such land reservations shall be noted on the final plan.
Recording the final plan after approval of the Board of Commissioners has the effect of an irrevocable offer to:
A. 
Dedicate all streets and other public ways to public use.
B. 
Dedicate all neighborhood parks and other public areas to public use.
C. 
Reserve for possible future public acquisition such additional areas as may be required by the Township.
