Mark Mayfair's storm drains so the block knows they drain to Coyote Creek

Mayfair's street drains run to Lower Silver and Coyote Creeks untreated, and driveway car work is a way of life on these blocks — which means oil and solvent at the curb reaches the creek the same afternoon. Bilingual curb markers on the unmarked inlets are cheap, proven source control for the neighborhood's own creek. Standard: City of San Jose stormwater inlet-marking practice; SDG 6 (Clean Water and Sanitation). Proof: Photo of each marked inlet plus location list Method (City of San Jose stormwater inlet-marking practice; SDG 6 (Clean Water and Sanitation).): 1. Map ten unmarked inlets on the assigned Mayfair blocks. 2. Sweep and dry each curb face. 3. Apply the bilingual 'No Dumping — Drains to Creek' marker beside each inlet. 4. Log each marker's cross-street. 5. Photograph every finished marker with its inlet. Done when: Photo of each marked inlet plus location list

Pay

$160 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

Photo of each marked inlet plus location list

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.
