A. 
As a condition of final site plan or subdivision approval, the Land Use Board shall require and the Borough Council shall accept in accordance with the standards of this chapter for the purpose of assuring the installation and maintenance of on-tract improvements:
(1) 
A performance guaranty in favor of the municipality in an amount not to exceed 120%, 10% of which shall be in cash, of the cost of installation for improvements if deemed necessary or appropriate, including streets, grading, pavement, gutters, curbs, sidewalks, streetlighting, shade trees, surveyor's monuments, water mains, culverts, storm sewers, sanitary sewers or other means of sewage disposal, drainage structures, erosion control and sedimentation control devices, public improvements of open space and other on-site improvements and landscaping.
(2) 
A maintenance guaranty to be posted with the governing body for a period not to exceed two years after final acceptance of the improvement, in an amount not to exceed 15% of the total cost of the improvement. 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 municipality for such utilities or improvements.
B. 
Performance guaranties for all improvements shall be provided and accepted prior to the signing of the final subdivision plat or the final site plan.
C. 
The form of the guaranty shall be as approved by the Borough Attorney, and the amount of guaranty shall be as determined by the Borough Engineer.
D. 
The applicant shall assume liability during construction of such improvements and until such time as the improvements are accepted by the Borough of Alpha.
E. 
Upon substantial completion of all required appurtenant utility improvements, and the connection to the same to the public system, the obligor may notify the governing body, in writing, by certified mail addressed in care of the Borough Clerk, of the completion or substantial completion of said improvements and shall send a copy thereof to the Board Engineer. Thereupon, the Board Engineer shall inspect all the improvements and shall file a detailed report, in writing, with the governing body, indicating either approval, partial approval or rejection of such improvements, with a statement of reasons for any rejection. The costs of the improvements as approved or rejected shall be set forth.
F. 
The governing body shall either approve, partially approve or reject the improvements on the basis of the report of the Board Engineer and shall notify the obligor, in writing, by certified mail, of the contents of said report and the action of said authority with relation thereto not later than 45 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, except for that portion adequately sufficient to secure provision of the improvements not yet approved, provided that 30% of the amount of the performance guaranty posted may be retained to ensure completion of all improvements. Failure of the governing body to send or provide such notification to the obligor within 45 days shall be deemed to constitute approval of the improvements, and the obligor and surety, if any, shall be released from liability pursuant to such performance guaranty for such improvements.[1]

G. 
If any portion of the required improvements are rejected, the approving authority may require the obligor to complete such improvements, and, upon completion, the same procedure of notification, as set forth in Subsections E and F above, shall be followed.
