Editor's Note: Schedule A, referred to herein, may be found as an attachment to this chapter.
B. 
The escrow amount required by Schedule A[2] shall be deposited with the Township prior to the issuance of any certificates of occupancy. All funds shall remain in an interest-bearing escrow account. The entire amount of any interest shall be applied to the purposes for which it was originally deposited.
C. 
All costs, expenses, charges and fees incurred by the Township for the maintenance of a detention/retention basin shall be charged against the escrow fund established for the maintenance of such a basin.
D. 
The Township will conduct maintenance programs at its discretion and shall maintain liability insurance on the basin out of the funds so created. The maintenance programs may include:
(1) 
Routine mowing of the property. Mowing costs shall be estimated at the rate of one acre per hour. The cost per hour for Township labor and equipment shall be multiplied by the number of acres to be mowed. A base number shall also be included for the mobilization and the maintenance of the equipment.
(2) 
Maintenance of landscaping. The cost shall be based upon the number of hours for landscape maintenance multiplied by a rate per hour for labor and equipment. Any and all additional stock which shall be necessary to replace approved landscaping shall also be charged against the fund.
(3) 
General maintenance. The cost for general maintenance shall be based upon a one hour mobilization time together with the total number of hours expended times the rate per hour for Township labor and equipment.
(4) 
Long-term maintenance. The long-term maintenance shall be calculated on a cost per acre and applied against the assumption that a residential detention/retention basin needs rejuvenation every 10 years. These amounts are reduced thereto an annualized cost.
(5) 
Calculation of the developer fund. The amount of money to be placed in escrow shall be calculated in accordance with the worksheet set forth in Schedule A. The first-year costs are multiplied by the factor of 28.24. Said calculation provides for the Township to receive sufficient funding for 25 years based upon an assumption of a 4% increase per year and a 2.75% return on investment earnings added to the account. The cost for the maintenance by the Township employees shall be based upon the amount of time services are performed, and the unit (i.e., per diem or hourly fee) of the professional, expert, employee or staff in accordance with the contracts or as prescribed by the salary ordinance of the Township of West Deptford.
