Should the developer fail in his/her obligation to maintain the site or subdivision in a safe and orderly condition, the City may, on five days' written notice or immediately in the case of hazard to life, health or property, undertake whatever work may be necessary to return the site or subdivision to a safe and orderly condition and deduct the cost thereof from the 10% cash or certified check portion of the performance guarantee. Upon notice of such deduction, the developer shall, within 10 days, restore the full 10% cash balance or his/her performance guarantee will be held to be void and the City may take action as if final plat approval had not been obtained.
