A. The time requirements of this section shall apply to all shoreline substantial development permits and to any development authorized pursuant to a shoreline variance or shoreline conditional use permit authorized by this chapter. Upon a finding of good cause, based on the requirements and circumstances of the project proposed and consistent with the policy and provisions of this SMP and this chapter, the town may adopt different time limits from those set forth in subsections B and C of this section as a part of action on a shoreline substantial development permit.

B. Construction activities shall be commenced or, where no construction activities are involved, the use or activity shall be commenced within two years of the effective date of a shoreline substantial development permit, shoreline conditional use permit, or shoreline variance. However, local government may authorize a single extension for a period not to exceed one year based on reasonable factors, if a written request for extension has been filed with a complete extension application submittal before the expiration date and notice of the proposed extension is given to parties of record on the shoreline substantial development permit and to Ecology.

C. Authorization to conduct development activities shall terminate five years after the effective date of a shoreline substantial development permit, shoreline conditional use permit, or shoreline variance. However, local government may authorize a single extension for a period not to exceed one year based on reasonable factors, if a written request for extension has been filed before the expiration date and notice of the proposed extension is given to parties of record on the shoreline substantial development permit, shoreline conditional use permit, or shoreline variance, and to Ecology.

D. The effective date of a shoreline substantial development permit, shoreline conditional use permit, or shoreline variance shall be the date of filing with Ecology as provided in RCW 90.58.140(6) and SPMC 15.14.630. The permit time periods in subsections B and C of this section do not include the time during which a use or activity was not actually pursued due to the pendency of administrative appeals or legal actions or due to the need to obtain any other government permits and approvals for the development that authorize the development to proceed, including all reasonably related administrative or legal actions on any such permits or approvals. The applicant shall be responsible for informing the town of the pendency of other permit applications filed with agencies other than the town and of any related administrative and legal actions on any permit or approval. If no notice of the pendency of other permits or approvals is given by the applicant to the town prior to the date of the last action by the town to grant permits and approvals necessary to authorize the development to proceed, including administrative and legal actions of the town, and actions under other town development regulations, the date of the last action by the town shall be the effective date.

E. Revisions to permits under SPMC 15.14.660 may be authorized after original permit authorization has expired; provided, that this procedure shall not be used to extend the original permit time requirements or to authorize substantial development after the time limits of the original permit.

F. The town shall notify Ecology in writing of any change to the effective date of a permit, as authorized by this section, with an explanation of the basis for approval of the change. Any change to the time limits of a permit other than those authorized by RCW 90.58.143 as amended shall require a new permit application. [Ord. 580 Att. A § 7.12, 2019.]
