Seawall bulkhead at 6' NAVD to combat sea level rise. II. Minimum walkway width — 12' III. Permeable materials to allow stormwater to percolate into the ground. • Raising portions of the existing road / realignment up to 1' from existing elevation • Living Shoreline installation to reduce erosion and address sea level rise. I. Marsh Grass planting. II. No new mangrove plantings are proposed. III. Variable width based on site conditions but maximizes shoreline protection and stabilization and park usage or useable park space • Permit to prune mangrove height and removal of non -mangrove trees. • Multiple access ramps within the living shoreline area maximize entry to shoreline. Existing trailway to traverse among the marsh grass areas. • Enhances bay view. FALSE !
