Photograph and log the winter flood spots around Lake Dalwigk after each big storm (2026-07-18)

The blocks around Lake Dalwigk detention basin are the first in Vallejo to pond in heavy rain, and the city's picture of exactly which corners flood is incomplete. A repeatable photo log of standing water — same corners, every storm — is the evidence that gets drainage fixes funded. Standard: FEMA community flood-documentation practice; SDG 13 (Climate Action). Proof: Same-vantage storm photo series with rainfall log Method (FEMA community flood-documentation practice; SDG 13 (Climate Action).): 1. Within 24 hours of a storm, walk a fixed route of eight known ponding corners near the basin. 2. Photograph each corner from the same marked vantage point every time. 3. Record water extent against fixed references like curb height and crosswalk lines. 4. Log date, time, and rainfall total from the nearest public gauge. 5. File the photo set and log as one dated record. Done when: Same-vantage storm photo series with rainfall log

Pay

$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.

Same-vantage storm photo series with rainfall log

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.
