The Grand Mound Urban Growth Area (UGA) sits southwest of Olympia, near the border of Thurston and Lewis counties. The unincorporated community of about 1,300 residents is attracting significant commercial development due to a prime location at the intersection of US Route 12, Interstate-5, and Old Highway 99. More growth is on the horizon, so the time is right to take stock of the area’s current conditions and future opportunities.
The Grand Mound Transportation Study will identify projects to improve safety and reliability of the transportation network in Grand Mound, as well as support access to businesses, improve connections for pedestrians and other users, and help develop the overall character of Grand Mound as it continues to grow. The project supports Thurston County’s update to the Grand Mound Subarea Plan.
Current Conditions Report. The Current Conditions Report (November 2018) summarizes the planning history of Grand Mound, current land use and development standards, and existing safety, congestion, and maintenance issues. A follow-up Existing Conditions Analysis (November 2019) includes more detailed analysis of key roadways, intersections, bicycle and pedestrian facilities, and collision history.
Public Engagement. TRPC conducted a survey of Grand Mound-area residents, hosted several community meetings, and gave presentations on the project to local groups. There will be additional public meetings in 2020.
Action Plan. The study identified transportation improvement projects that address safety concerns, improve congestion, and provide better connections for all people who travel in and through Grand Mound.
Transportation Element. The study will update goals and policies for the Transportation Chapter of the Grand Mound Subarea Plan, and identify any needed changes to current standards or regulations to meet those goals.
