Hydrographic Surveys

Surrounded by water, the Pacific Northwest boasts a thriving marine industry as well as waterfront living.  CWLS provides hydrographic survey services to both commercial and residential applications.  Whether you are building a new bulkhead or developing a marina, CWLS has the experience and expertise to support your project.

A hydrographic survey is a topographic survey of the bottom of a water body.  This survey is typically required for the design, improvement or permitting of a water dependent structure.  We perform this work by creating a surface grid that displays subsurface depth using depth soundings determined by a variety of techniques, equipment, and procedures.
