Seattle's Mayor and two City Councilmembers are members of the Growth Management Planning Council of King County (GMPC). The GMPC is a body of elected officials from across the county that oversees implementation of the state's Growth Management Act, making decisions about where and how new households and employment should be accommodated. The comprehensive plans of all the cities in the county, and of the county itself, must be consistent with the GMPC's decisions.

Staff in DPD's Comprehensive and Regional Planning Unit provide support to the City's GMPC members and to the GMPC as a whole. For more on the GMPC, visit their website.
