DESCRIPTION
The primary objective of the Feeder Bluff and Armor Removal Assessment project was to build a prioritized list of private and publically-owned armor removal projects in Island and East Jefferson Counties that were feasible and would benefit down-drift shoreforms and habitat.
The project was a targeted development strategy, informed by both sound science and landowner values and concerns, to identify priority projects and build landowner willingness. Private land owners do not typically view armor removal as an acceptable option and consistently identify ‘erosion’ as their main concern (CGS landowner needs assessment 2010, NWSF landowner needs assessment 2012). Without educational opportunities and/or incentives, landowners are unaware of alternatives and their benefits. Shoreline armor embodies many contradictory aspects of human relationships with nature, as it is often perceived as benefiting human well-being despite negatively affecting ecosystem goods and services (Leschine 2010). Landowner outreach and education, along with clear incentives for positive action, were used to pursue armor removal on privately owned land. The messaging and content of this project’s targeted outreach reflected the values and concerns identified in landowner needs assessment surveys conducted in priority areas and removal would not be recommended at sites where structures would be at risk without armor.
The project consisted of three phases of work: Phase One was a technical analysis using existing data sets including feeder bluff mapping, drift cells, Puget Sound Nearshore Ecosystem Restoration Project (PSNERP) strategies and shoretypes, LIDAR, habitat mapping, and parcel data layers to identify and prioritize bluff restoration sites with the highest potential to restore processes. Sites were sorted by restoration priority and by landowner type. This technical assessment and database development was performed by Coastal Geologic Services.
Phase Two used the technical analysis to develop and implement a targeted outreach strategy to increase awareness of coastal processes, encourage the consideration of alternatives to hard shoreline armoring, and establish landowner willingness for armor removal. Workshops for private landowners and direct outreach to managers of public lands provided education on coastal processes and shoreline armor impacts as well as a venue for engaging with decision makers. Free technical site visits offered to landowners gave a site-specific assessment and gauged feasibility based on a combination of factors: structure and septic setback distances; bluff recession rates; and armor removal benefit (location w/in drift cell; proximity to forage fish spawning habitat; proximity to pocket estuaries and natal streams, etc.). This phase was led by the Northwest Straits Foundation and accomplished in collaboration with the Island and Jefferson Marine Resources Committees (MRCs) and Coastal Geologic Services.
Phase Three forwarded the site assessments to permit-level designs for those properties where removal was feasible and landowner willingness was obtained. Four projects were identified that would restore sediment supply to shoreline process units through the removal of the shoreline armor. Northwest Straits provided the landowner coordination and Coastal Geologic Services completed the designs. Companion funds from Washington Departments of Fish and Wildlife and Natural Resources also allowed for the start of the permitting process and work towards implementation of the projects.
