Springline Design is a Seattle based civil engineering design firm established in 2004 by two principals with over 25 years experience in the Pacific Northwest.

Our founders have provided design services for a wide range of public and private clients, including Parks Departments, Port Districts, Housing Agencies, and Municipalities.

Our design philosophy centers around providing civil engineering site design services which are focused on meeting regulatory requirements in creative and cost effective ways, and providing those services in the context of a holistic site design approach. This holistic approach is manifested in our detailed consideration of, and collaboration with, all the design disciplines present on a given design team, and provides our clients with the highest level of design and construction document coordination. We examine in detail all the improvements proposed for a project, regardless of discipline, to ensure cost effective and predictable construction costs.
