A performance guaranty, sufficient to cover the cost of resurfacing performed in accordance with §
186-5, will be deposited in the manner stated in §
186-4B, and the amount will be computed as follows.
When it is deemed necessary by the Borough Engineer
to excavate by breaking the surface of the road or street and the
result can be obtained by driving pipe under the road or street, the
same deposit shall be made. No excavation or driving under the road
will be allowed to be done where sheet asphalt, bituminous concrete,
bituminous macadam, brick or concrete surface exists except in the
presence of the Borough Engineer or his authorized agent.
The property owner and/or contractor will pay
an inspection fee to the borough, the cost of which will be determined
by the Borough Engineer or designate. In determining the inspection
fee, the Borough Engineer or designate will take into account the
type and amount of street to be opened. Said inspection fee shall
be $200 for the first 10 square yards to be opened and $10 for each
additional 10 square yards to be opened, and in no case shall the
inspection fee be less than $200. Inspections will be carried out
by the Borough Engineer or designate.
