A. 
Before final approval of a site plan, the municipal agency may require, in accordance with the standards adopted by ordinance, the furnishing of a performance guaranty of all or any of the following improvements it may deem to be necessary or appropriate: street grading, pavement, curbs, sidewalks, fire hydrants and boxes, street signs, street-lighting, shade trees, surveyors' monuments, water mains, culverts, bridges, storm sewers, sanitary sewers or other means of sewage disposal, drainage facilities and easements therefor or structures and other improvements as the municipal agency may require or deem necessary in the public interest, even though said improvements may be required to be located outside the property limits of the subdivision or development, so long as same are necessitated or required by construction or improvement within such subdivision or development, and provided further that the developer shall not be required to pay more than his pro rata share of the cost of such off-tract improvements.
B. 
The municipal agency shall establish fair and reasonable standards to determine the proportionate or pro rata amount of the cost of such facilities that shall be borne by each developer or owner within a related or common area, which standards shall not be altered subsequent to preliminary site plan approval.
C. 
The developer may pay under protest the amount determined to be his pro rata share. However, such developer shall be required to institute legal action within one year of such payment under protest in order to preserve his right to a judicial determination as to the fairness or reasonableness of the amount allocated by the municipal agency as his pro rata share.
A. 
All improvements specified by this Part 4 or required by the municipal agency shall require the posting of a performance guaranty to assure the installation of the required improvements prior to approval of any final plan.
B. 
Such performance guaranty may be in the form of a performance bond which shall be issued by a bonding or surety company approved by the Borough, a certified check returnable to the landowner after full compliance or other type of surety approved by the Borough Attorney.
C. 
The performance guaranty shall be approved by the Borough Attorney as to form, sufficiency and execution.
D. 
The amount of any performance guaranty may be reduced by the Mayor and Borough Council by resolution when portions of the improvements have been completed, and the time allowed for installation of the improvements for which the performance guaranty has been provided may be extended by the Mayor and Council by resolution.
E. 
If the required improvements shall not have been installed or corrected in accordance with the performance guaranty, the obligor and surety, if any, shall be liable thereon to the Borough for the reasonable or corrected cost of the improvements not installed or corrected, and, upon the receipt of the proceeds thereof, the Borough shall install such improvements.
F. 
When all of the necessary and appropriate improvements have been completed, the obligor shall notify the Mayor and Borough Council in writing, by certified or registered mail, of the completion of the aforesaid improvements and shall send a copy thereof to the Borough Engineer. The governing body shall direct and authorize the Borough Engineer to inspect all of the aforesaid improvements. The Borough Engineer shall thereupon file a report, in writing, with the governing body, which report shall be detailed and shall indicate either approval, partial approval or rejection. If said improvements or any portion thereof shall not be approved, the reports shall contain a statement of reasons for such nonapproval or rejections. Where said report indicates partial approval of improvements, it shall indicate the cost of the improvements for which approval is rejected or withheld.
G. 
The Mayor and Borough Council shall accept or reject the improvements, grant partial approval or withhold approval on the basis of such report and shall notify the obligor in writing, by certified or registered mail, of the contents of said report and the action of the governing body with relation thereto no later than 65 days after receipt of notice from the obligor of the completion of the improvements. Where partial approval is granted, the obligor shall be released from all liability pursuant to its performance guaranty bond, except for that portion adequately sufficient to secure the improvements not yet approved.
H. 
Failure by the governing body to send such notification to the obligor within 65 days shall be deemed to constitute approval of the improvements, and the obligor and surety shall be released from all liability pursuant to such performance guaranty.
I. 
If any portion of said improvements shall not be approved or shall be rejected by the Borough Council, the obligor shall cause the same to be completed, and, upon completion, the same procedure of notification as outlined herein shall be followed.
J. 
The obligor shall be responsible for all of the inspection fees of the Borough Engineer incurred in making the foregoing inspections. Nothing herein shall be construed to limit the right of the obligor to contest by legal proceedings any determination of the municipal agency or Borough Engineer. In no event shall the municipal agency require the furnishing of a performance guaranty in an amount in excess of 120% of the cost of installation or improvements it may deem necessary or appropriate.
K. 
Nothing herein shall affect the obligation of any person relating to the posting of appropriate maintenance bonds as provided in § 390-140.
In accordance with N.J.S.A. 40:55D-53a(2), as amended, the Borough of Ridgefield shall require the posting of a maintenance guaranty for a period not to exceed two years after final acceptance of the improvement, in an amount not to exceed 15% of the cost of the improvements or of the original installation as determined by the Borough Engineer. In the event that other governmental agencies or public utilities automatically will own the utilities to be installed or the improvements are covered by a performance or maintenance guaranty to another governmental agency, no performance or maintenance guaranty, as the case may be, shall be required by the Borough for such utilities or improvements.
