About us

At Cogan Owens Greene, our history goes back to the foundation of the land use planning system in Oregon.  Founding Principal Arnold Cogan was hired by then Governor Tom McCall to lead the community outreach and engagement to turn the vision of Senate Bill 100 into a reality. The change then and today was to thoughtfully determine, together, how to grow and thrive in community and economy while protecting irreplaceable natural assets and resources. In 1973, with his team from the Governor’s office, Arnold engaged more than 10,000 Oregonians in the drafting of the original land use planning goals – the structure and concepts that continue to guide our work and integrated community planning today.

At Cogan Owens Greene, we bring people together to create and sustain great communities that are best equipped to face the challenges of the present and the future. We take this responsibility seriously. Cogan Owens Greene embraces the goal of advancing integrated planning in the community context. We are recognized for our ability to “tell the story” of community planning and engage all stakeholders in the planning process – including those who have not traditionally been engaged. We recognize that opportunities are often disguised as unsolvable problems, and believe that anything is possible with collaboration, open communication and respect.
