Bulkhead and bank armoring rules. Even more important in reducing impacts to coastal resources, now as well as with future sea level rise, is addressing bulkhead and shore armoring. One tool is to require the removal or modification of bulkheads and shore defense works currently on Tribally-owned tidelands. Another option is to tighten the rules regarding bulkheads and shore defense works within the current SSA ordinance. New bulkheads and hard armoring could be prohibited except in narrow circumstances or in certain areas. Existing hard bank protection repair could be restricted in some areas or require replacement with softer practices in certain cases.
