needed to serve future growth. The following description and data are taken from King County and Pierce County Buildable Lands analyses. 2014 King County Buildable Lands Analysis After deducting for constraints, future rights-of- way, and public-purpose needs, and applying a market factor, the King County Buildable Lands Analysis shows that Auburn has approximately 2,150.5 adjusted net acres of vacant and redevelopable residentially zoned land available for the planning period through 2031. As seen in Table 2, the majority of available land for development is zoned for single-family residential purposes. Based on the residential land supply analysis and historical densities, an estimate of housing unit capacity was developed. Table 2 identifies the estimated capacity (in housing units) in King County by aggregated zoning type. This estimate shows a capacity of approximately 14,597 housing units in the King County portion of the City through 2031.

A uburn in the F uture – P rojections of G rowth The Puget Sound Regional Council, King County, Pierce County, and the City of Auburn need to understand growth projections, patterns,and implications for a 20- to 30-year planning horizon. Based on various models and analyses, available developable land, population data, and expected economic trends, jurisdictions can better understand industrial, commercial, and residential land supply and capacity. This understanding can then be used to extrapolate future available housing units and employment growth. The primary data tools for planning for future growth are county-prepared buildable lands analyses. These reports establish the parameters by which cities and counties jointly plan for both residential and job growth. As a two-county city, the City of Auburn coordinates with both King and Pierce Counties in determining growth projections, land supply, and the adequacy of urban services
