The City is currently engaged in a two-phase effort to update the City Center Plan, adopted in 1999. Information about Phase 1, completed in 2020, can be found here: Phase 1: Updating the Vision.

About the City Center Plan
In 1999 the City completed a subarea plan for the City's central commercial core. The map at the right shows the area of the City covered by the City Center Plan, as it appeared in an aerial photo taken in 1999. The plan identifies transportation system improvements in the area, as well as design standards for new development in the area that the City hopes will result in high quality development.  The design standards can be found in the Zoning Code, Chapter 15.35.

In December 2010 the City amended the City Center Plan [PDF] to incorporate some provisions of the SeaTac/Airport Station Area Action Plan, which was rescinded at the same time. The amendments included:

• Removing the collector streets from Figure 5.1 (map)
• Updating policies for new development to provide adequate vehicular and pedestrian access and circulation
• Prohibiting new park-and-fly developments unless located in parking structures, and
• Including updated descriptive and background information regarding light rail station locations

In addition to downloading the Plan from this page, copies are also available at the Planning Division at City Hall.
