If the Water Master Plan calls for a larger water main than is presently needed for service to property being developed, the water main shall be oversized by the Developer to the satisfaction of the Director. If authorized by the City Council, the City will reimburse the developer for the costs of materials of the oversizing. Prior to reimbursement, the developer will provide the City with an itemized accounting of the costs of materials for the oversized water main extension as constructed and an estimate of the cost of pipe and other materials of the size which would have served the development if oversizing had not been required. Prior to reimbursement, the developer will also provide certification that all material and labor charges have been paid. (Ord. 88-23 §33, 1988).
