Install erosion control at the ridge to marsh ecotone, site 4, the Gambusia Nature Trail boardwalk, Sea Rim State Park, 19335 S. Gulfway Drive, Sabine Pass, TX 77655, Jefferson County

The survey above found undercutting or slumping at this chenier ridge to marsh ecotone, and TPWD coordinated boardwalk-top erosion control is the concrete step that slows the loss of the ridge edge the park's boardwalk and habitat depend on.

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

TPWD coordination confirm plus before after photos plus material record plus 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

• Confirmation the site and erosion control plan were coordinated with Sea Rim State Park staff
• Before photo of the eroding ridge or dune edge
• Confirmation work stayed on the boardwalk or dune top at all times, never stepping down into the marsh or onto the bank below
• Confirmation no alligator or other wildlife was approached, fed, or baited
• Erosion control material installed recorded
• After photo of the finished install from the matching vantage

Proof is measured against these, not judged by taste.

The standard this serves

Coastal Habitat. Coastal habitat is the green fringe where land meets sea: eelgrass meadows, kelp beds, salt marsh. Acre for acre these are among the most life-giving places on Earth, nursery to the fish and buffer to the storm, and NOAA's assessment methods exist because they are quietly shrinking. Mastery looks like a person who can survey a stretch of shore and say, with evidence, whether the meadow is spreading or retreating. This packet is one piece of that watching: one site, one careful observation, one record added to the long ledger of the coast.
