Darren Gurnee

Current Planning Supervisor, Kitsap County

I could argue, my planning and design experience exceeds 44 years - starting while in infancy and throughout my childhood. My father as a city councilman, Director for City of Morro Bay, and owner of a multidisciplinary planning firm for 30 years (RRM Design Group) provided hours of looking at aerial photographs and topography maps during my childhood while designing regional parks or agricultural/residential clustering projects.

My formal experience in the planning and construction industry, recently emphasizes current planning and permit review supervision. Before current planning, my public planning career emphasized long range planning including management of multiple code update projects. Many of these subarea plans and code updates within Kitsap County required extensive countywide outreach campaigns and presentations. Almost each project included a public participation plan prepared for, and presented to, the Board of County Commissioners.

My private planning experience includes multiple projects ranging from residential subdivisions to complex mixed-use commercial, office, industrial developments, water rights and allocation, through a balance of both private and public clients. These projects included hands-on work assisting my clients in sensitive environmental and political settings. As with any position, this required a strong commitment to professional standards including high-quality, innovative and responsible design, technical writing, and public outreach.a
