In 1997, the Washington State legislature adopted the Buildable Lands amendment to the Growth Management Act, (RCW 36.70A.215). The amendment requires six Washington counties and their cities to determine the amount of land suitable for urban development, and evaluate its capacity for growth, based upon measurement of five years of actual development activity. King County and the other five counties must report to the State by September 1, 2002 and every five years thereafter.

Major elements of the Buildable Lands program include:

  • annual data collection to determine the amount and density of new development;
  • updated inventories of the supply of land suitable for development;
  • assessment of the capacity of each jurisdiction and the entire Urban Growth Area to accommodate expected growth;
  • preparation of a Five-Year Evaluation Report; and (later)
  • adoption of remedial measures where necessary to address density and capacity shortfalls.

The data gathering and analysis to prepare this Evaluation Report was performed by all 40 jurisdictions in King County, under the auspices of the Countywide Planning Policies (CPPs) adopted and amended in 1994. This Report is our combined response to both the Buildable Lands amendment and the direction provided in the CPPs. Further, each jurisdiction is examining its data in light of its own comprehensive plan.
