The subdivider shall guarantee all public improvements for a period of one year from the date of final acceptance and shall correct any and all defects or deficiencies arising during said period as a result of the acts or omissions of the subdivider, his agents or employees. The subdivision guarantee shall be backed by a bond or cash deposit in the amount of 15 percent of the surety posted for improvements. The City shall provide written notice of the defect or deficiency. In any instance where the subdivider fails to take action within the specified time, or when immediate action is required to protect the public health, safety and/or welfare, the City may cause the work to be performed and call on the surety for reimbursement.
