Shoreline Armor Reduction Program (SHARP)
SHORELINE ARMOR REDUCTION PROGRAM (SHARP)
Northwest Straits Foundation
As part of the Shoreline Armoring Removal Project (SHARP) through the Northwest Straits Foundation and prior grants, CGS has completed nearly 120 individual property site visits for commercial and residential landowners to document site characteristics and provide recommended action. Site visits followed 14 “Living with the Coast” workshops in all seven North Puget Sound served by the Marine Resource Committees. Whether the concern involved bluff landslides, beach erosion, or habitat restoration through armor removal or other actions, site visits by our licensed professionals helped landowners make important decisions about their properties. Work continues in all seven counties in 2017.
Feeder Bluff Restoration Assessment for Island and East Jefferson Counties (2014-15)
FEEDER BLUFF RESTORATION ASSESSMENT FOR ISLAND AND EAST JEFFERSON COUNTIES (2014-15)
Northwest Straits Foundation
This 3-phase, multi-scalar project was aimed at developing feasible, high-benefit bluff restoration (armor removal) projects that are ready for implementation. The first phase entailed a GIS assessment to assess the feasibility and projected benefit of armor removal for all parcels in the study area that contained armored feeder bluffs. Outreach to property owners was offered through workshops and individual site visits. Site visits were conducted to verify feasibility, inform landowners, and inform design if willingness was achieved. Several feeder bluff restoration designs are currently in development for willing property owners.
Marine Shoreline Design Guidelines
MARINE SHORELINE DESIGN GUIDELINES
WA Dept. of Fish and Wildlife
The Marine Shoreline Design Guidelines was recently completed by Coastal Geologic Services for the Washington Department of Fish and Wildlife. The document covers techniques for assessing and managing erision in the context of Puget Sound. Guidance is provided for soft shore and hard shore protection techniques, including resloping and revegetating banks (with assistance from QWG Applied Geology). CGS has conducted initial full day trainings on the guidance document and is continuing to provide trainings for WDFW and others in 2014.

BEACH DESIGN AND SHORELINE ENHANCEMENT AT BOULEVARD PARK, BELLINGHAM
City of Bellingham
Balancing the competing demands for redeveloping a busy waterfront park with a highly degraded shore, establishing new beaches, and enhancing recreation and habitat challenged CGS and our consulting teams to create a balanced approach approved by Parks, the public, and agencies. CGS’ partial bulkhead removal, new beach designs, and traditional erosion control structures now allow the City’s thousands of park and beach enthusiasts to enjoy waterfront access and more than 240 linear feet of new beach areas enhanced for recreation and habitat.
Spencer Spit SLR Vulnerability
SEA LEVEL RISE VULNERABILITY STUDY OF SAN JUAN COUNTY
Using EPA funding along with Friends of the San Juans
As more and more communities experience the effects of erosion and climate change, assessing future coastal hazards due to climate change and sea level rise is becoming critical for managing our coasts. CGS paired inundation modeling with future bluff recession estimates under two SLR scenarios and developed a mapping tool to create and adapt management strategies to reduce, avert, and mitigate vulnerabilities. These results and tools are now used to identify long-term restoration and conservation targets throughout the County, and are seen as an example of new quantitative analysis for the region.
PSNERP
BEACH AND COASTAL STRUCTURE DESIGN FOR PORT ANGELES’ WATERFRONT & TRANSPORTATION IMPROVEMENT PLAN
City of Port Angeles/Consultant Team
Converting 2,000 linear feet of heavily altered waterfront and turning it into a community-friendly destination is just the challenge CGS needed to develop a wave model and complete the final design for two beaches. The property is owned by WDNR and the City of Port Angeles, and currently has a 20 foot high rock revetment in from of several city blocks of fill. We designed pocket beaches with more than 370 linear feet of functional gravel beach shoreline with a broad sand-covered backshore and provided input on beach access features and adjacent reaches.
