Photo-document bare-soil and dust conditions on Cudahy blocks in the Exide zone — record only, never touch (2026-07-18)

Cudahy, one of the densest small cities in California, lies inside the Exide lead-cleanup footprint, and many of its long narrow lots still show bare, dusty side yards where children play. A standing photographic record from public sidewalks, updated quarterly, tracks which blocks remain bare and keeps the state cleanup accountable to this community. Standard: DTSC Exide residential cleanup program documentation; SDG 3 (Good Health and Well-being). Proof: Per-block condition photos plus change log Method (DTSC Exide residential cleanup program documentation; SDG 3 (Good Health and Well-being).): 1. Walk the assigned Cudahy blocks and photograph every visible bare-soil yard strip, dust track, and unpaved parking pad from the public sidewalk. 2. Log each condition against its address range on the survey sheet without entering any property. 3. Flag on the sheet any bare area beside a visible play space. 4. Compare against the prior quarter's sheet and mark changes. 5. Photograph the completed sheet with date and GPS at the final corner. Done when: Per-block condition photos plus change log

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

Per-block condition photos plus change 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: EPA soil screening (composite surface sample, XRF/field kit)

Bring

• trowel or auger
• clean bucket + mixing tool
• XRF analyzer or metals test kit
• PID for volatiles (if petroleum in scope)
• sample bags + labels
• N95 dust mask
• gloves + eye protection
• GPS phone
• camera

Steps

1. 1. Navigate to the parcel; record GPS; sketch a >=5-point sampling grid.
2. 2. Photograph each sampling point and any visible staining/fill/slag.
3. 3. Collect 0-15 cm cores from >=5 points; combine and mix in the clean bucket; subsample.
4. 4. Run XRF/test kit on the composite; record each metal in ppm.
5. 5. If petroleum is in scope, log PID readings and any odor/staining.
6. 6. Bag/label any lab subsample; complete chain-of-custody.
7. 7. Enter all analytes with units, depth, GPS, photos, and site sketch into the proof record; sign.

If it does not match the plan

• Lead > 400 ppm (residential) -> tag exceedance; advise raised beds / produce-washing / cover; recommend lab confirm.
• Arsenic > site screening level or PID indicating volatiles -> tag; recommend certified-lab confirmation before reuse.
• Suspected asbestos-containing material -> do not disturb; flag and stop.

What counts as done

• >=5-point composite collected at 0-15 cm
• Each screened metal recorded in ppm
• Visible staining/fill/slag noted (or absence)
• GPS waypoint + point photos + grid sketch

Proof is measured against these, not judged by taste.
