New SEPA Exemption for Housing Proposals

Seattle has made considerable progress in planning for housing growth in both its comprehensive plan and land use codes. In recognition of that progress, the Washington State Legislature has amended (Senate Bill 5412) the State Environmental Policy Act (SEPA) to help reach those goals by expediting the review of development that includes housing. As of July 23, 2023, most projects proposing additional housing units will be exempt from SEPA review, including several types of residential and mixed-use developments that would have previously undergone SEPA review. This SEPA change does not affect other SDCI discretionary approvals, such as Design Review, that may be required for specific proposals. This SEPA amendment will be in effect until September 30, 2025, when the Seattle Comprehensive Plan Update provides new housing growth targets and updated SEPA thresholds.

SEPA Parking Amendments Effective January 20, 2023

On January 20, 2023, the state proposed SEPA related amendments removed parking as an element of the environment and revised the environmental checklist.  As a result of new state law, SDCI will no longer identify and analyze parking impacts in its SEPA analysis.  A new Environmental (SEPA) checklist is available on the City forms page and required with submittal of a Master Use Permit for project proposals that require SEPA.

SEPA Decision for Seattle’s Permanent Floodplain Development Regulations

In February of 2020, the Federal Emergency Management Agency (FEMA) required Seattle to update our floodplain regulations to include FEMA’s new Flood Insurance Rate Maps (FIRM) and the Flood Insurance Study (FIS). FEMA’s adoption of the new map and study also included an audit of Seattle’s floodplain regulations. Through the audit, FEMA identified several places in Seattle’s code that needed to be amended in order to comply with the minimum standards in the Code of Federal Regulations (CFR). FEMA included the following required amendments in their audit: new definitions and updates to existing definitions to meet minimum standards; updates to the regulatory floodway development standards; and the inclusion of newly mapped coastal high hazard flood zone (VE zone) and required regulations for this zone.
