Sweep the Heron's Head Park shoreline clean each month (2026-07-19)

Heron's Head is Bayview's restored wetland jewel — real salt marsh, real shorebirds, on a community's industrial waterfront. Tide and wind load its trail edges with plastic that ends up in the marsh channels where birds feed. A monthly trail-side sweep protects the one place in the neighborhood where the bay is being healed instead of used. Standard: California Coastal Cleanup data-card protocol; SDG 14 (Life Below Water). Proof: Before/after trail photos plus weighed tally Method (California Coastal Cleanup data-card protocol; SDG 14 (Life Below Water).): 1. Walk the park's public trails with bags, gloves, and grabbers. 2. Collect litter from trail edges and dry upper margins only — never the marsh, channels, or mudflats. 3. Tally item types on the data card and sort recycling. 4. Weigh and stage bags at park bins. 5. Photograph before and after plus the tally card. Done when: Before/after trail photos plus weighed tally

Pay

$180 proposed

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 trail photos plus weighed tally

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.
