Our History

Cushing Civil Engineers was established in 1996 to serve local public, private, and commercial clients by offering the full spectrum of civil engineering expertise in site development.

Founded in Portland, we have since expanded to have offices in both Oregon and Florida, while completing engineering projects all over the United States. To better serve our clients and achieve project goals we have established valuable relationships with surveyors, mechanical, structural and electrical engineers, planners, environmental specialists, and landscape architects.

Our mission at Cushing Civil Engineers has always been to preserve and protect the general welfare of the public, by carefully planning and having open discussions about our project strategies. Over the past 23 years, our founder, Don Cushing, has made public presentations to City Councils, Planning Commissions, Hearings Officers and Engineering Departments.
