Project Team


The project team for this effort combines the best of local, regional and national talent.  Following a twelve-month selection process, GHD Inc., working from their Santa Rosa office, was selected to lead this important assignment.  GHD has been in Sonoma County for nearly 30 years, and has worked on other complex, high-profile projects for local agencies (i.e. Geysers Recharge Pipeline Project).  GHD has also designed over 350 Roundabouts throughout the US, Canada and abroad. Assisting GHD with the effort is a wide range of consultants that bring expertise, insight and local knowledge.

From the start to October 2017, UrbanGreen,, a local urban design and sustainable strategies firm, provided local community outreach.  This process was structured to create understanding and connectivity to the unique qualities and concerns of Healdsburg throughout the process and final design solution.

The City of Healdsburg public communications and community outreach coordinator took over community outreach in October 2017 and continues to the present day.  This outreach includes weekly online newsletters of construction progress, in-person visits with local merchants, social media updates, and creation of, a narrative series on Healdsburg small-business owners whose businesses are located near the roundabout.
