Keep a weekly freight-corridor air diary from public sidewalks beside the 710 in Lynwood (2026-07-18)

Lynwood's east side sits against the 710 freeway, one of the busiest diesel truck corridors in the country, and residents live with the soot that comes off it. A steady, dated photo-and-observation diary from public sidewalks — truck counts, visible exhaust, dust, odor notes — builds the neighborhood's own record to bring to air-district meetings. Standard: South Coast AQMD community air monitoring (AB 617 community practice); SDG 3 (Good Health and Well-being). Proof: Two-point diary sheet plus corridor photos, weekly Method (South Coast AQMD community air monitoring (AB 617 community practice); SDG 3 (Good Health and Well-being).): 1. Stand at the same two public sidewalk points near the 710 overcrossings at the same hour each week. 2. Count trucks passing for ten timed minutes at each point and note wind, visible exhaust, dust, and odor. 3. Record nearest public air-sensor readings (such as PurpleAir or AQMD) for the same hour. 4. Log everything on one diary sheet per visit. 5. Photograph the corridor view and the completed sheet at each point with date and GPS. Done when: Two-point diary sheet plus corridor photos, weekly

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

Two-point diary sheet plus corridor photos, weekly

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.
