NOE - Notice of Exemption
Repair and replace a 120 foot section of existing, storm-damaged boardwalk and 120 feet of stairways and trail step along the Moonstone Beach boardwalk at Hearst San Simeon State Park to restore public access along the coastal trail and to the beach.
At the Moonstone Beach boardwalk, work will:
" Remove and replace an approximately 120 foot section of existing boardwalk that has been undermined by bank erosion, and re-align the boardwalk away from the bluffs, connecting each end of the re-aligned section to the existing, undamaged, boardwalk.
" Install the boardwalk support structure consisting of approximately thirty 2" x 6" x 7 feet long pressure treated pads and 4" x 4" vertical supports at 4 foot intervals connected by 4" x 4" horizontal runners extending the full length of each side of the boardwalk.
" Reconstruct the boardwalk tread with 2" x 6" x 7" tread boards and finish with 4" x 4" edge rail set on 2" x 4" x 12" spacers set every 3 feet on each side of the structure.
" On the ocean ward side of the boardwalk, install a safety barrier consisting of fifteen 6" diameters, 54" long peeler core posts, each set in 24" deep, 8" diameter holes, with a finish height of 30" above ground. Backfill with natural soils and drill and attach a ½" coated safety cable through each post to complete the safety barrier.
At the Moonstone Beach Drive stairway, work will:
" Remove and replace approximately 20 existing storm damaged stairway steps/water bars with five foot long, 6" x 6" pressure treated lumber, secured with 2 food long ½ inch rebar.
" Restore the tread surface with approximately 1 cubic yard of imported class 2 road base or decomposed granite and out-slope the trail tread for erosion control.
" Remove and replace approximately 15 handrail posts with 5 ½ foot long, 6" diameter peeler core posts set in 24" deep, 8" diameter re-excavated post holes, backfilled with natural soils, with a finish height of approximately 42 inches. Cap the safety railing with ½ inch coated cable symbolic barricade.
" Stabilize the base of the stair structure and trail approach with a 12 foot long, 24 inch high retaining wall constructed of 6" x 6" pressure treated lumber secured by 6" diameter peeler core posts, set 24 inches in the ground. Backfill the retaining wall with approximately 2 cubic yards of crushed rock or aggregate material.
