Log the tide-flood high-water mark on a Muara Baru seawall street (2026-07-18)

North Jakarta is sinking up to several centimeters a year from groundwater draw-down, and tidal 'rob' flooding now reaches Muara Baru and Penjaringan streets on ordinary high tides, not just storms. Neighbors need a simple, repeated public record of how high the water actually reaches so drainage and seawall requests can be backed by real numbers instead of guesses. Standard: UN-Habitat urban flood-risk monitoring guidance; SDG 11.5 (reduce disaster impacts). Proof: Timestamped photo of waterline + log sheet + GPS Method (UN-Habitat urban flood-risk monitoring guidance; SDG 11.5 (reduce disaster impacts).): 1. Stand on dry public pavement at the marked observation point at high tide. 2. Photograph the current waterline against a fixed reference (curb, post, wall marking). 3. Record the date, time, and tide stage in the log sheet. 4. Note any visible drainage blockage or pump status from the public vantage point. 5. Upload the photo set and log entry as proof. Done when: Timestamped photo of waterline + log sheet + GPS

$80 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

Timestamped photo of waterline + log sheet + 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 45–90 minutes. Method of record: FEMA floodplain + green-infrastructure siting screen

Bring

• GPS phone
• tape/ruler for deposition depth
• metals field kit (if sediment screen in scope)
• boots + gloves
• camera

Steps

1. 1. Confirm post-event conditions are safe; navigate to the site; record GPS.
2. 2. Photograph deposited sediment / affected area.
3. 3. Measure deposition depth at representative points.
4. 4. If a sediment contaminant screen is in scope, run the metals field kit and record values.
5. 5. Note debris, hazards, and the extent (sketch).
6. 6. Enter depth, any analytes, hazard notes, GPS, photos into the proof record; sign.

If it does not match the plan

• Unstable ground / submerged debris / contaminated water -> document from safe footing; do not enter.
• Elevated metals in deposited sediment -> flag before any reuse; recommend lab confirm.

What counts as done

• Deposition depth recorded at representative points
• Metals screen recorded (if in scope)
• Debris/hazard note + extent sketch
• GPS waypoint + timestamped photos

Proof is measured against these, not judged by taste.
