Stencil 'Drains to the Bay' markers on south Vallejo storm drains

Storm drains in the flat blocks around Lake Dalwigk carry street runoff straight to the detention basin and out to the Mare Island Strait — no treatment in between. Most neighbors do not know that. Curb markers are the cheapest known way to cut dumped oil, paint, and pet waste at the source. Standard: Municipal MS4 stormwater public-education marking programs; SDG 6 (Clean Water and Sanitation). Proof: Photo of each marked inlet plus the location list Method (Municipal MS4 stormwater public-education marking programs; SDG 6 (Clean Water and Sanitation).): 1. Map ten unmarked storm drain inlets on residential blocks around Lake Dalwigk Park. 2. Sweep each curb face clean and dry it before marking. 3. Apply the 'No Dumping — Drains to Bay' stencil or adhesive marker squarely beside each inlet. 4. Log each marked inlet's cross-street on a simple list. 5. Photograph every finished marker with its inlet in frame. Done when: Photo of each marked inlet plus the location list

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.

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 30–60 minutes. Method of record: EPA dry-weather / AMD field screening

Bring

• GPS phone
• pH meter or strips
• conductivity meter
• ammonia + iron test kit as specified
• surfactant screen if specified
• gloves
• camera

Steps

1. 1. Navigate to the outfall/reach; record GPS; photograph it, capturing any visible flow or staining.
2. 2. Note whether flow is present in dry weather (yes/no).
3. 3. Measure and record pH, conductivity, and each specified analyte per kit instructions.
4. 4. Log any color, odor, floc, or aquatic-life observation.
5. 5. Enter all readings with units, GPS, time, and photos into the proof record; sign.

If it does not match the plan

• Dry-weather flow present with elevated conductivity/ammonia/surfactants -> flag suspected illicit discharge for the responsible agency.
• pH < 6 with visible iron floc -> tag suspected acid mine drainage; recommend metals lab panel.

What counts as done

• pH + conductivity recorded with units
• Each specified analyte recorded with a value
• Dry-weather flow present? recorded yes/no
• GPS waypoint + timestamped photo

Proof is measured against these, not judged by taste.
