Photograph the king-tide high-water line along Eureka's bayfront (2026-07-18)

Humboldt Bay has the fastest relative sea-level rise on the U.S. West Coast, and during winter king tides the water already reaches over low spots along Eureka's working waterfront. The city needs a dated photo record of exactly where the water reaches each season so drainage fixes and shoreline projects go where the water actually goes, not where a map guesses. Standard: California King Tides Project photo-monitoring practice + FEMA community flood resilience guidance; SDG 13 Climate Action. Proof: Dated king-tide photo set from fixed public vantage points Method (California King Tides Project photo-monitoring practice + FEMA community flood resilience guidance; SDG 13 Climate Action.): 1. Check a tide table and pick a king-tide or highest-tide morning for your visit. 2. Walk the public boardwalk and street ends between C Street and the foot of Del Norte Street, staying on pavement. 3. At each low spot, photograph the water line against a fixed landmark like a piling, curb, or rail. 4. Note the time, tide height from the table, and whether water is over any path or pavement. 5. Repeat the same route each visit so photos compare season to season. 6. Upload all photos with GPS location and date to complete the record. Done when: Dated king-tide photo set from fixed public vantage points

$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.

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.
