Coastal Geologic Services was founded in Bellingham, Washington in 1993 by Jim Johannessen, a coastal geologist and licensed engineering geologist. The company was founded to fill a need for high-quality analysis and design for applied coastal management and engineering focused on the unique shoreline environments of Puget Sound and the Salish Sea. Since its inception, CGS has completed coastal assessment, design and management projects for a broad range of coastal landowners and all levels of government, including tribes.

With completed projects and mapping and management products for every Puget Sound area county and lower British Columbia, we bring a deep knowledge and understanding of coastal processes in our region to design site-specific and cost-effective solutions that are within the reach of landowners and land managers.


We are a small, integrated group with complimentary skill sets in the many aspects of coastal and estuarine processes and design. Click on each staff member’s photo for a detailed description.
