Keep a weekly photo log of truck and shipyard air along the Barrio Logan fenceline (2026-07-18)

Barrio Logan sits pressed between working shipyards, the Interstate 5 corridor, and port truck routes, and state screening ranks its pollution burden in California's top tier. Residents smell diesel daily but the record of idling trucks, visible plumes, and dust events is thin. A steady, dated photo log from public sidewalks gives neighbors standing evidence for the state's community air protection program. Standard: CARB AB 617 Community Air Protection (Portside communities) — SDG 11. Proof: Dated photo log from the fixed public route with notes Method (CARB AB 617 Community Air Protection (Portside communities) — SDG 11.): 1. Walk the same public sidewalk route along Cesar E. Chavez Parkway and Harbor Drive each week at a consistent hour. 2. Photograph idling trucks, visible exhaust plumes, uncovered loads, and dust events from the sidewalk. 3. Note the time, wind direction, and any strong odors in a simple written log entry for each photo. 4. Upload the week's photos and log with GPS location and date stamps to close the record. Done when: Dated photo log from the fixed public route with notes

$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

Dated photo log from the fixed public route with notes

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 NAAQS community ambient-air screening (PM2.5)

Bring

• calibrated PM2.5 monitor
• GPS phone
• wind/weather note source
• hi-vis vest
• camera

Steps

1. 1. Choose >=3 points (near-source/roadside, mid, background); record GPS at each; stay off the roadway.
2. 2. Photograph each monitoring location.
3. 3. Log PM2.5 (ug/m3) at each point over a comparable peak period.
4. 4. Record wind direction, time, and nearby source activity (e.g., truck traffic).
5. 5. Compare readings to the NAAQS reference.
6. 6. Enter the PM2.5 logs, wind/time, source note, GPS, photos into the proof record; sign.

If it does not match the plan

• Roadside work near heavy traffic -> stay off travel lanes; hi-vis at all times.
• Near-source PM2.5 well above background and NAAQS -> flag an environmental-justice exposure concern.

What counts as done

• PM2.5 logged at >=3 points (near-source / mid / background)
• Wind direction + time recorded
• Source-activity observation recorded
• GPS waypoints + location photos

Proof is measured against these, not judged by taste.
