Build a rain garden — Los Angeles, CA

Rain gardens capture runoff and recharge groundwater — grounded green-stormwater work (SDG 6). Standard: SDG 6 (Clean Water) — green stormwater infrastructure, rain gardens. Proof: before/after photos + GPS + planting list Method (SDG 6 (Clean Water) — green stormwater infrastructure, rain gardens.): 1. Lay out the rain-garden/GSI footprint. 2. Excavate and shape to spec (inflow, ponding, overflow). 3. Plant natives and mulch. 4. Photograph before/after with GPS. Done when: before/after photos + GPS + planting list

$70 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 photos + GPS + planting list

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 45–120 minutes. Method of record: SDG 6.1/6.3 (safe water, reduce pollution) — sample or inspect to a fixed protocol so results compare across sites and dates

Bring

• test kit for named analytes
• clean sample bottles + labels
• nitrile gloves
• thermometer
• camera + phone with GPS

Steps

1. Photograph the site BEFORE with GPS on and a legible timestamp; confirm you are inside the posting radius.
2. 2. Confirm the sampling point matches the posting; record the waypoint.
3. 3. Photograph the source with a legible timestamp.
4. 4. Label the bottle BEFORE filling: site, date, time.
5. 5. Fill without touching the bottle interior; cap immediately.
6. 6. Run each test per kit instructions, waiting the exact development time.
7. 7. Record every reading with its unit and the water temperature.
8. 8. Record all results, GPS, and time into the proof record and sign it.

If it does not match the plan

• Reading exceeds the named health threshold -> tag the exceedance and advise certified-lab confirmation; do not tell anyone the water is safe.
• Kit is past its expiry -> results are not evidence; stop.
• Development time missed -> rerun that test; a late read is not a result.
• Source is visibly contaminated or inaccessible -> document and do not sample.

What counts as done

• Before and after photos from the same position, GPS inside the posting radius, timestamps legible
• Bottle labelled before filling, visible in a photo
• Every reading recorded with its unit
• Water temperature recorded
• Kit expiry confirmed in date
• Exceedances tagged with a lab-confirmation recommendation

Proof is measured against these, not judged by taste.
