A. The city council may require a reasonable performance bond as provided in Section 17.96.140 as a condition of approval to ensure conformance with its decision.

B. Surface excavation activities shall not begin until a bond to guarantee completion of an approved reclamation plan has been obtained by the applicant. If a Washington Department of Natural Resources (DNR) surface excavation permit is required for the project, the city council may allow substitution of the DNR bond to meet this requirement. The bond shall be maintained in force until reclamation is complete and approved by the department.
