Fact Sheet: The Case for a Boundary Adjustment on 39th Ave SW

Posted on February 16, 2026

1. The Core Issue: “The Planning Mismatch”

The Draft One Seattle Plan proposes Lowrise 2 (LR2) zoning for the east side of 39th Ave SW (between Holly and Juneau). While the City’s 2D map identifies this as a “Neighborhood Center” expansion, the physical “ground-truth” contradicts the zoning intent.

2. Anti-Displacement: Protecting “Naturally Affordable” Housing

The City’s own 2026 Displacement Risk Indicators Dashboard identifies West Seattle as an area of heightened market pressure.

  • The Teardown Incentive: Rezoning this residential mid-block to LR2 creates an immediate financial incentive for developers to demolish older, stable homes.
  • Net Loss of Stability: Replacing multi-generational homes with high-end, market-rate condos does not meet the City’s social housing goals; it displaces current residents for higher-income luxury units.

3. Infrastructure Constraints: 8-Inch Sewer & Stormwater Capacity

  • The Utility Gap: 39th Ave SW is currently served by an 8-inch sanitary sewer main, which is the minimum standard for single-family residences.
  • Capacity Overload: Transitioning to LR2 (which can increase density by 400%) risks “surcharging” (overflowing) these lines during heavy rainfall, a risk already identified in SPU’s 2025 system reports.
  • Drainage Risk: The 39th Ave slope makes the 70–90% lot coverage allowed under LR2 a severe stormwater runoff risk for downhill neighbors.

4. Topographical Reality: The Slope from Morgan to Raymond

  • Massing Conflict: A 40-foot building (allowed in LR2) dropped onto our street’s steep grade will loom over neighboring properties, blocking sunlight and destroying privacy transitions.
  • Narrow Access: 39th Ave is a residential interior street, not a transit corridor. It lacks the width and “spine” infrastructure required to support construction staging or increased urban-scale traffic.

5. The Proposed Solution: “Targeted Correction”

  • Request: Maintain Neighborhood Residential zoning for the 39th Ave SW mid-block.
  • Benefit: This allows for “middle housing” (ADUs/Triplexes) consistent with state law (HB 1110) while preserving the vital Residential Buffer that protects the core of Morgan Junction.

    Dear Panning commission, In regard to the proposed zoning changes along 39th Ave SW. I have a very obvious question…
