Run a monthly litter sweep along the south Vallejo waterfront on Mare Island Strait (2026-07-19)

The public shoreline south of the Vallejo ferry landing collects wind-blown trash and creek-borne plastic that washes into the Mare Island Strait and out to San Pablo Bay. Herons and shorebirds feed on this mudline. A monthly bag-and-weigh sweep keeps the tide line clean and produces a running record. Standard: California Coastal Commission cleanup data-card protocol; SDG 14 (Life Below Water). Proof: Before/after shoreline photos plus weighed-bag tally Method (California Coastal Commission cleanup data-card protocol; SDG 14 (Life Below Water).): 1. Walk the public shoreline path from the ferry landing south toward Lake Dalwigk outfall with bags, gloves, and a grabber. 2. Collect litter above the wet mudline only, staying on the paved path and firm ground. 3. Sort into trash and recycling, and tally the top five item types on a data card. 4. Weigh the filled bags with a hand scale and stage them at a public trash point. 5. Photograph the tide line before and after, the tally card, and the weighed bags. Done when: Before/after shoreline photos plus weighed-bag 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 shoreline photos plus weighed-bag 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.
