Keep the weekly air and truck log on National City's Westside (2026-07-18)

National City's Westside grew up interleaved with auto shops, freeway ramps, and port-serving industry, and it shares the Portside communities' state air-program designation for good reason. A weekly dated log of idling, plumes, odors, and dust from public sidewalks builds the evidence record the program runs on. Standard: CARB AB 617 Community Air Protection (Portside communities) — SDG 11. Proof: Weekly dated photo log from the fixed route Method (CARB AB 617 Community Air Protection (Portside communities) — SDG 11.): 1. Walk the same Westside public route weekly at a consistent hour. 2. Photograph idling trucks, visible exhaust, and dust events from the sidewalk. 3. Log time, wind, and odor notes per event. 4. Upload photos and the log with GPS and date. Done when: Weekly dated photo log from the fixed route

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.

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.
