Draft One Seattle Plan Update (2024)

Draft Housing Appendix

Since its initial adoption in 1990, the state Growth Management Act (GMA) has required local comprehensive plans to inventory and analyze existing and projected housing needs. The draft Housing Appendix addresses these requirements and provides a wealth of additional data to inform housing policies in the One Seattle Plan, consistent with GMA and regional frameworks.

The state Legislature recently strengthened GMA so that Seattle and other jurisdictions must “plan for and accommodate” housing affordable to all economic segments of the population. Our draft Housing Appendix documents Seattle’s share of projected housing needs for low- and moderate- income households and for emergency housing and shelters and provides analysis on zoned development capacity to meet these needs. In addition, the draft Housing Appendix:

  • Analyzes trends in demographics and housing supply and costs, demonstrating the importance of expanding the diversity of housing types and unit sizes, including moderate density housing and family-sized units affordable at lower cost than traditional detached housing.
  • Discusses barriers to fully address existing and future housing needs, including funding necessary to meet needs among low-income households through housing subsidies. 
  • Documents disproportionate housing challenges faced by households of color and maps existing disparities in access to key components of livability.
  • Analyzes policies and practices that have resulted in racially disparate impacts, exclusion, and displacement and, along with the Anti-Displacement Framework identifies areas that may be at higher risk of displacement as the city grows.

DEIS Public Hearings

The public hearings are an opportunity for individuals and groups to provide verbal comment on the DEIS. Commenters will be asked to sign up on a form that will be available online one hour before the hearing or in-person 15 minutes before the hearing. Commenters will be asked to speak in the order that they signed up, alternating between online and in-person commenters. There will be a two minute time limit for each commenter. Links for online commenters will be available prior to the event.

An EIS provides information about potential environmental impacts and mitigating measures from a proposal to inform the decision-making process. The scoping report summarizes what we've heard and how we are updating the proposed approach to analysis.
