Anchor erosion-control matting at an eroding bluff-trail edge, segment 1 -- Point Arena-Stornetta Public Lands bluff trails, near Point Arena Light, Point Arena, CA 95468

A segment of the Stornetta bluff-top trail is actively eroding at its seaward edge, undercutting the tread and threatening to narrow or close a public trail on this California Coastal National Monument unit. Standard: NOAA coastal habitat assessment (eelgrass / kelp / salt marsh extent + condition); SDG 14.2 sustainable marine ecosystems. Proof: before/after photos + anchor tug-test log + matting-area spec + GPS Method (NOAA coastal habitat assessment (eelgrass / kelp / salt marsh extent + condition); SDG 14.2 sustainable marine ecosystems.): 1. 1. ASSESS: with the BLM/State-Parks trail crew supervisor, walk the eroding trail-edge segment and confirm which sections are stable tread vs. an actively undercut/crumbling bluff edge; photograph the segment as found. 2. 2. Stage erosion-control matting and anchor stakes; work only from the stable tread side, never standing on or leaning over an undercut edge. 3. 3. Roll out and anchor the matting flush to the trail tread, staking it at the spacing the manufacturer/crew plan specifies so it will not lift in the next storm or high-wind event. 4. 4. VERIFY: tug-test each anchor point, photograph the finished, secured matting from the matching before vantage, and flag any section too undercut to safely matt for a licensed geotechnical follow-up. Done when: before/after photos + anchor tug-test log + matting-area spec + GPS

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

before/after photos + anchor tug-test log + matting-area spec + GPS

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–120 minutes. Method of record: NOAA coastal habitat (eelgrass / salt marsh) extent + condition

Bring

• tide table
• GPS phone
• quadrat frame
• measuring tape
• boots/waders
• camera

Steps

1. 1. Check the tide table; plan to work the low tide; tell someone your plan and return time.
2. 2. Navigate to the habitat edge; record GPS waypoints along the patch/edge.
3. 3. Photograph the meadow/marsh at low tide.
4. 4. Record shoot/stem density per quadrat and estimate patch extent (or edge scarp height for marsh).
5. 5. Note condition (epiphytes, dieback, wrack) and adjacent land use/armoring.
6. 6. Enter density, extent, condition, GPS, photos into the proof record; sign.

If it does not match the plan

• Soft mud / rising tide -> stop and retreat; safety over data.
• Edge retreat or heavy dieback observed -> flag for living-shoreline / protection planning.

What counts as done

• Density (shoots/stems per quadrat) recorded
• Patch extent or edge position recorded via GPS
• Condition + adjacent-use note recorded
• Low-tide photos + GPS waypoints

Proof is measured against these, not judged by taste.
