Prior to expiration of the land disturbance permit, the land disturbance permit holder may apply for an extension of time in which to complete the work in a reasonable and expeditious manner. The city engineer may grant an extension of time, upon a showing of good cause, for a period or periods not exceeding a total of one year. Denial of an extension of time does not preclude the right of the land disturbance permit holder to apply for a new land disturbance permit for the remaining balance of the work. Adequate security or written consent from the surety must be provided for any extension of time before approval of the extension is granted or becomes effective. If the extension is denied, the city will make a demand on the bond and complete the work. (2001 Code § 81-2-220)
