Grand Mound & Rochester Subarea Plans

Upcoming Open House - March 7th, 2020


Grand Mound and Rochester are rural communities in southwest Thurston County. Grand Mound was established as an Urban Growth Area (UGA) in 1995 as a means to curb urban sprawl. Development is concentrated within the UGA, while areas outside are reserved for rural use. In 1996, separate development and zoning plans were adopted as Subarea Plans to address the unique needs of each community. These Subarea Plans are being updated now as part of the County's Comprehensive Plan Update process to ensure the visions and goals meet the current community's objectives.
