On February 12, more than 120 people attended an open house to provide feedback on three preliminary concepts for South Lake Union’s future urban form. The concepts were developed in a two-day workshop hosted by the South Lake Union Friends and Neighbors Community Council (SLUFAN). SLUFAN will now review comments received on the concepts and will make a recommendation to the Mayor for alternatives to be considered during environmental review of changes to the neighborhood’s zoning. For more information please see www.seattle.gov/DPD/Planning/SLU and www.slufan.org.
The three main concepts are:
Transit Corridors and Nodes Option
- Existing transit corridors and future East-West streetcar route provide focus for increased density and transit use.
- Identifies Dexter, Westlake, Mercer, Fairview and Harrison Avenue as high-density corridor opportunities.
Edge Transitions Option
- New zoning envelope responds to adjacent areas.
- Majority of density at edges (Denny & Dexter).
- Provides “two-sided” high-density development corridor along Denny Way with massing balanced to match Denny Triangle rezone.
- Cascade neighborhood remains lower density area.
- Minimized height south of Lake Union park and shoreline.
- Development and density respects lake frontage and Kenmore Air flight path.
Parks Focus Option
- Denny Park, Lake Union Park and Cascade Playground provide focus for new higher density development.
- Less additional development capacity added around Cascade Playground.
- Linkage between high-rise and adjacent open space provides human-scaled streetscapes.
