(1) Grading permits shall expire 24 months from the date of issuance; provided, that the director may set an earlier expiration date for a permit, or issue a permit that is nonrenewable, or both, if the director determines that soil, hydrologic, or geologic conditions on the project site necessitate that grading and drainage improvements and site stabilization be completed within less time.

(2) If a permit has expired, the applicant shall obtain a renewed permit before starting work authorized under the expired permit.

(3) A permit may be renewed once for up to 24 additional months except as provided in SMC 17.154.150, and a request for renewal shall be made no later than 30 days after the date of expiration of the original permit.

(4) Requirements under this chapter that are not expressly temporary during the grading operations, including, but not limited to, requirements for erosion control, drainage, and slope management, do not terminate with the expiration of the grading permit. (Ord. 1499 § 10 (Exh. H), 2021).
