NSD + CGS specializes in coastal engineering design in the Puget Sound region, focusing on restoration design and rehabilitation and modernization of previously developed coastal areas such as parks and water access areas. We execute all elements of nearshore design, including site conditions characterization, feasibility assessment, design alternatives analysis, stakeholder engagement, preliminary and final construction design, permitting, and construction oversight.  

We often model coastal waves and circulation (see the Coastal Modeling services page) and factor in projected sea level rise and associated coastal recession/erosion to inform design.


NSD + CGS performs coastal engineering services at the full suite of coastal sites, including at contaminated waterfront sites as part of site cleanup design.
