Coastal Geologic Services Inc. offers a full suite of services for coastal landowners. We provide cost-effective solutions that work with rather than against natural coastal processes and the constraints of shoreline regulations and existing land uses. We can also take into consideration implications of sea level rise and climate change.
CGS has worked for landowners for almost 30 years, and continues to provide targeted and cost-effective advice and erosion control design services. We have completed hundreds of assessments throughout the Puget Sound region and are recognized regional experts in Puget Sound beach and bluff processes. In addition, we have literally written the book on how to effectively manage your coastal property, and we regularly teach workshops designed for living on the shore. Read on for more information on the services we provide.
Coastal Erosion and Flooding Assessment and Control
CGS offers design services for green, sustainable alternatives to bulkheads that use aesthetic, non-toxic, and shore friendly approaches and materials — for both people and wildlife. These designs minimize maintenance and are typically much less expensive than traditional bulkheads. CGS can help assess erosion and flooding risk to your property through remote analysis and a site visit, then recommend action, create a design, get it permitted, and oversee construction. Realistic site-specific projections of sea level rise enable planning for future generations.
“I want you to know how much I appreciate the work of your staff on the permit application. Adam’s documentation and presentation to the County was flawless and very professional.”

Bluff Slope Stability Assessment and Recommendations
We have analyzed coastal bluff erosion throughout the region. Our team can evaluate bluff erosion risk and recommend ways to mitigate it. We can often suggest low-cost erosion control actions such as re-routing runoff or planting low-maintenance native vegetation. In more dangerous situations, we have helped property owners to move their house landward. Contact CGS for a professional assessment of your property.
“We’re not going to wonder…is that house going to fall into the water? We know those things are not going to happen because we’ve made good long-term decisions now….”

CGS staff can assist you when buying or selling a coastal home by completing a pre-purchase assessment. This involves a professional CGS staff member conducting a detailed site visit to look for problems and “red flags”. If you are a Realtor, CGS can help you to work with potential buyers to ensure a successful long-term investment.
Our process will address all of your specific concerns, such as potential property loss due to natural hazards. In many cases, we will characterize the threat of coastal erosion, coastal flooding, landslide hazards, tsunami hazards, sea level rise implications, and — in some cases — any evident issues with shoreline structures (e.g. bulkheads or over-water structures). CGS will provide professional, impartial judgement to characterize and qualify the level of risk involved in purchasing a coastal property.
“This very cost-effective review gave us a great understanding of the risks and responsibilities of owning coastal properties. I would strongly recommend CGS’s services if you are considering investing in coastal properties. “— Homeowner on Fidalgo Island, 2018
Beach Restoration and Enhancement
CGS is capable of doing all design phases for nearshore restoration and enhancement projects, including restoration identification, design technique feasibility, permitting assistance, design, construction oversight, and monitoring. Beach restoration and enhancement design projects vary based on specific constraints, but a CGS design process typically includes:
- Plan sheets
- Project design report
- Cost estimate
- Recommended contractor and subcontractor qualifications to be used for the bid evaluation
- Construction sequence
- Recommendations for any additional investigations or reporting
CGS uses many different methods for site investigation, including historical shore change analysis, RTK GPS mapping, total station topography, and structure from motion photogrammetric scanning for surface and orthographic image generation.

CGS has experience with design and construction of the full suite of beach and bluff protection alternatives, from soft shore protection (i.e., beach nourishment, anchored logs and large wood placement, reslope/revegetation) to bulkhead removal or replacement. Depending on conditions at your site, CGS can assess, design, permit, and oversee construction of an effective and lasting shore protection solution.
