South Lake Union

We proposed to amend the Seattle Municipal Code to strengthen the incentive to preserve open space in the South Lake Union Urban Center. This amendment will preserve the Seattle Times Park as publicly accessible open space as part of the development project proposed on the site of the former Seattle times Building.

An appeal period for a Environmental Impact Statement Notice of Determination closed on June 29, 2019. Please take a look at the Project Documents page to review the Determination of insignificance, the Directors Report describing the proposal in detail, and the legislation.

Implementation Legislation


In 2004, the Seattle City Council designated the South Lake Union Neighborhood as one of the City’s six Urban Centers. This designation reflected the recent growth in both jobs and housing in the neighborhood and signified that South Lake Union will continue to receive a regionally significant share of growth in the future. Since 2004, we have updated the South Lake Union Neighborhood Plan, worked with the community to develop the South Lake Union Urban Design Framework, and developed an incentive zoning ordinance that was adopted by the City Council in 2013.

Through the incentive zoning program, projects may gain extra floor area or height by providing affordable housing and participating in a regional transfer of development rights program. This program will provide capacity for up to 12,000 households and 22,000 new jobs over the next 20 years. This program is expected to generate approximately $45 million for affordable housing and $27 million in new infrastructure investments, and will preserve 25,000 acres of rural farm and forest land over the next 25 years.
