Before any improvements are accepted by the Borough,
the applicant shall deposit with the Borough Clerk a maintenance guaranty
in the amount of 10% of the estimated cost of the improvements, as
estimated by the Borough Engineer, but in no event in an amount less
than $1,000. The maintenance guaranty shall be for a period of two
years and shall provide for the proper repair or replacement, if necessary,
of any such improvements during a two-year period. The two-year period
shall be from the date of the acceptance of the guaranty by the Borough.
Every maintenance guaranty shall contain the following clause: "It
is hereby understood and agreed that in the event the principal shall
default in the performance of this obligation under this obligation,
then surety shall perform the principal's obligation at the option
of the obligee."
