The obligor shall reimburse the municipality for all reasonable inspection fees paid to the Municipal Engineer for the foregoing inspection of improvements: provided that the municipality may require of the developer a deposit for all or a portion of the reasonable anticipated fees to be paid to the Municipal Engineer for such inspection. For those developments for which the reasonably anticipated fees are $10,000 or greater, fees may, at the option of the developer, be paid in four installments. The initial amount deposited by a developer shall be 25% of the reasonably anticipated fees. When the balance on deposit drops to 10% of the reasonably anticipated fees because the amount deposited by the developer has been reduced by the amount paid to the Municipal Engineer for inspection, the developer shall make additional deposits of 25% of the reasonably anticipated fees. The Municipal Engineer shall not perform any inspection if sufficient funds to pay for those inspections are not on deposit.
