(23) To require the posting of financial security to insure the completion in accordance with the approved plat and with the rules and regulations of the authority of any water mains or sanitary sewer lines, or both, and related apparatus and facilities required to be installed by or on behalf of a developer under an approved land development or subdivision plat as these terms are defined under the act of July 31, 1968 (P.L.805, No.247) , known as the Pennsylvania Municipalities Planning Code. If financial security is required by the authority and without limitation as to other types of financial security which the authority may approve, which approval shall not be unreasonably withheld, federally chartered or Commonwealth-chartered lending institution irrevocable letters of credit and restrictive or escrow accounts in these lending institutions shall be deemed acceptable financial security. Financial security shall be posted with a bonding company or federally chartered or Commonwealth-chartered lending institution chosen by the party posting the financial security if the bonding company or lending institution is authorized to conduct business within this Commonwealth. The bond or other security shall provide for and secure to the authority the completion of required improvements within one year from the date of posting of the security. The amount of financial security shall be equal to 110% of the cost of the required improvements for which financial security is to be posted.
The cost of required improvements shall be established by submitting to the authority a bona fide bid from a contractor chosen by the party posting the financial security. In the absence of a bona fide bid, the cost shall be established by an estimate prepared by the authority' s engineer. If the party posting the financial security requires more than one year from the date of posting 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 the initial posting date or to 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. As the work of installing the required improvements proceeds, the party posting the financial security may request the authority to release or authorize the release of, from time to time, portions of the financial security necessary to pay the contractor performing the work. Release requests shall be in writing addressed to the authority, and the authority shall have 45 days after receiving a request to ascertain from the authority engineer, certified in writing, that the portion of the work has been completed in accordance with the approved plat. Upon receiving written certification, the authority shall authorize release by the bonding company or lending institution of an amount estimated by the authority engineer to fairly represent the value of the improvements completed.
If the authority fails to act within the 45-day period, it shall be deemed to have approved the requested release of funds. The authority may, prior to final release at the time of completion and certification by its engineer, retain 10% of the original amount of the posted financial security for the improvements.
If the authority accepts dedication of all or some of the required improvements following completion, it may require the posting of financial security to secure structural integrity of the dedicated improvements as well as the functioning of the improvements in accordance with the design and specifications as depicted on the final plat and the authority's rules and regulations. This financial security shall expire not later than 18 months from the date of acceptance of dedication and shall be of the same type as set forth in this paragraph with regard to that which is required for installation of the improvements, except that it shall not exceed 15% of the actual cost of installation of the improvements. Any inconsistent ordinance, resolution or statute is null and void.
