What is the Planning Commission?

Posted on February 16, 2026

The Seattle Planning Commission does not pass final laws, but its technical recommendations carry significant weight with the City Council and the Mayor.

Here is a look at who they are, how they function, and how they fit into the current “Centers and Corridors” debate in West Seattle.

What is the Planning Commission?

The Commission is an independent, 16-member volunteer body that advises the city on broad planning and land-use policies. Think of them as the city’s technical conscience. They are tasked with looking at the 20-year horizon, rather than just the immediate political cycle.

How They Are Formed

To ensure a balance of perspectives, the seats are split:

  • 7 members appointed by the Mayor.
  • 7 members appointed by the City Council.
  • 1 member appointed by the Commission itself.
  • 1 “Get Engaged” member (a young adult position).

The “District 1” Connection

Since you are in West Seattle (District 1), you have a local voice at the table. Xio Alvarez, one of the current Co-Chairs, is a resident of District 1 (White Center/Highland Park) and is a designer at LMN Architects. Having a local representative as a Co-Chair means the “ground-truth” of our district is well-represented in their internal discussions.

Their Role in the “Centers and Corridors” Rezoning

For the current Phase 2 of the One Seattle Plan, the Commission’s role is to provide a formal “Letter of Recommendation” to the City Council.

  1. Technical Review: They analyze the “Director’s Report” from OPCD. They look at things like whether the proposed LR2 zoning on 39th Ave SW actually meets the city’s anti-displacement and housing goals.
  2. Public Bridge: They serve as one of the first formal opportunities for public testimony before the legislation reaches the Council.
  3. The “Lever”: If the Commission highlights a “planning mismatch” in their formal letter, it provides the City Council with a technical justification to move the zoning lines.

How to Influence the Commission

Because they are a volunteer advisory body, they often appreciate detailed, fact-based testimony more than purely emotional pleas.

  • Attend the Meetings: They typically meet on the second Thursday of each month (3:00 PM – 5:30 PM) and the fourth Thursday (7:30 AM – 9:00 AM) in a hybrid format at City Hall (Room L280) and on MS Teams.
  • Submit Written Testimony: You can email their Executive Director, Vanessa Murdock, at vanessa.murdock@seattle.gov. Written comments submitted 8 hours before a meeting are shared with all commissioners.
  • Focus on “The Plan”: In your testimony, reference the Comprehensive Plan’s goals. If you show them that LR2 on your block conflicts with the Plan’s own “Policy 1.4” regarding neighborhood stability, you are speaking their language.

Current Leadership (2026)

  • Co-Chairs: Xio Alvarez and Matt Hutchins.
  • Executive Director: Vanessa Murdock.
  • Council Liaison: Councilmember Eddie Lin (who also chairs the Land Use Committee).

To help you influence the Seattle Planning Commission, here are the specific principles they use to evaluate zoning changes and the direct contact information for their staff.

The Commission’s Evaluation Principles

The Planning Commission doesn’t just look at maps; they evaluate proposals through a specific “Lens of Stewardship.” When you speak or write to them, framing your concerns using these four core values will make your testimony much more impactful:

  1. Race and Social Equity: This is their top priority. They look for whether a rezone will displace vulnerable communities. You can argue that LR2 on 39th Ave SW triggers the teardown of older, “naturally affordable” homes, which harms equity.
  2. Environmental Stewardship: They value green space and tree canopy. You can point out that the steep slope and narrow lots of 39th Ave SW make it difficult to maintain the existing tree canopy if high-density LR2 buildings are shoehorned in.
  3. Community: They look for “complete, walkable neighborhoods.” You can argue that your block already serves as a vital residential buffer, protecting the “community feel” of the Morgan Junction core.
  4. Economic Opportunity and Security: They want to ensure residents can stay in their homes. You can frame the rezone as a threat to the economic security of long-term residents who have invested in their properties.

How to Contact the Commission

The most effective way to reach the commissioners is through their executive staff, who ensure your comments are entered into the formal public record.

  • Primary Email for Testimony:vanessa.murdock@seattle.gov
    • Vanessa Murdock is the Executive Director. Send your formal letters here.
  • Staff Liaison for Agendas:robin.magonegil@seattle.gov
    • Robin Magonegil manages the distribution lists. Email her to be added to the official meeting notification list.
  • General Phone: (206) 684-8694

Pro Tip: When you email Vanessa, ask her to “distribute your comments to the full Commission” for their next meeting. This ensures all 16 commissioners see your specific request for the 39th Ave SW boundary adjustment.

Upcoming Deadlines for You

  • Written Comments: To be included in the “meeting packet” for the commissioners, you should email your comments at least 8 hours before their scheduled meetings (which are usually the 2nd and 4th Thursdays).
  • March Hearing: The Commission will likely be finalizing their “Letter of Recommendation” to the City Council in mid-March. Now is the perfect time to get your “Morgan to Raymond” walk invitation into their inbox.
