Bulkhead removal: Bulkheads and riprap represent one of the most significant barriers to shoreward migration of beach and habitat, in addition to causing negative impacts to existing shoreline resources. Removal of bulkheads and shore defense works where legally required or otherwise feasible, as well as stricter regulation to prevent construction of new bulkheads and shore defense works, is key to shoreline restoration and adaptation to sea level rise where the desire is to preserve natural shoreline processes. Obviously, such removal projects by the Tribe would be easiest were the bulkheads or shore defense works are on lands owned by the Tribe. Tribally-owned shoreline properties with rip rap include leased lands, such as in Shelter Bay, and dikes along the Swinomish Channel. The Tribe may acquire other uplands with bulkheads or other shore defense works, either through purchase or through the shoreward shift of the MWH mark with sea level rise. Once a structure is on land owned by the Tribe, a determination can be made on whether to remove it or modify it to reduce impacts on shoreline resources. Another approach might be to seek cooperation with upland landowners, who own a bulkhead on uplands, and for the Tribe to pay for removal of the structure. The advantage to the Tribe is removal sooner rather than at some later date when the structure has come to encroach on Tribal tidelands. The advantage to the upland owner may be money saved rather than being required to remove it, at their own cost, at some later date and more certainty in planning for the future. As an added incentive, this could include allowing replacement with soft bank protection if removed now, but no replacement if left for future removal.
