WHEREAS, the permanent floodplain regulation proposal has not yet been transmitted to Council; thus, the Seattle Department of Construction and Inspections now seeks another extension of the interim floodplain regulations to be in place while the City deliberates on the permanent floodplain proposal; NOW, THEREFORE,

BE IT ORDAINED BY THE CITY OF SEATTLE AS FOLLOWS:

Section 1. The City Council makes the following legislative findings of fact and declares as follows:

A. The Council incorporates by reference the findings of fact contained in Ordinance 126113.

B. In July 2020, the City Council passed, and the Mayor signed Ordinance 126113, establishing interim floodplain development regulations to maintain the City’s standing in the Federal Emergency Management Agency’s (FEMA’s) National Flood Insurance Program, enabling residents to continue to be eligible for flood insurance while preventing development incompatible with City goals related to development in the floodplains.

C. Since that time, the City has proposed permanent floodplain development regulations that included the amendments proposed in the interim regulations and additional code amendments and published a new State Environmental Policy Act (SEPA) decision on this proposal; however, due to factors detailed below, the work necessary to complete the permanent regulations will not be completed before the expiration of the interim regulations on February 4, 2026.

D. The City’s initial SEPA decision, published in July 2021, was appealed to the Hearing Examiner by the Port of Seattle (“Port”) and Port and City staff subsequently worked to resolve the issues raised by the Port with code amendments, Director’s Rules, Tips, and a variance guidance document.

E. The City withdrew its SEPA decision in February 2022 in order to reissue an updated SEPA analysis on the amended proposed permanent Floodplain Development Regulations that address some or all issues raised by the Port of Seattle.

F. The City issued a new SEPA decision in August 2024 and this decision was not appealed. However, the Port of Seattle continues to request additional amendments, and additional constituents have requested additional engagement with the City and FEMA.

G. Revised Code of Washington (RCW) 36.70A.390 authorizes the City to renew interim regulations by ordinance for a six-month period.

Section 2. Pursuant to RCW 36.70A.390, the interim regulations first set forth in Ordinance 126113, and as amended by Ordinance 126536, shall be renewed for a period of six months from the date this ordinance becomes effective, and shall automatically expire after the six-month period unless the same is extended as provided by statute, or unless terminated sooner by the City Council.

Section 3. This ordinance, which is not subject to referendum, shall take effect: immediately after its approval by the Mayor; immediately after its unsigned return by the Mayor; if the Mayor disapproves it and the Council upon reconsideration passes it again, immediately after that passage; or, if not returned by the Mayor within ten days after presentation, 15 days after its passage by the City Council.

Passed by the City Council the ________ day of _________________________, 2025, and signed by me in open session in authentication of its passage this _____ day of _________________________, 2025.
