If the Borough determine that the amount in escrow for the payment of inspection fees is insufficient to cover the cost of additional required inspections, the Borough may require the developer to deposit additional funds in escrow provided that the Borough delivers to the developer a written inspection escrow deposit request, signed by the Borough Engineer, which:
1. Informs the developer of the need for additional inspections;
2. Details the items or undertakings that require inspection;
3. Estimates the time required for those inspections; and
4. Estimates the cost of performing those inspections.
