Repair eroded levee-toe riprap, site 2 -- the Sacramento River levee near Corning, CA 96021.

The survey flagged site 2 along this levee with riprap displaced and the toe slope actively undercutting; placing engineered riprap back to design grade at the toe stops that undercutting before it threatens the levee's structural integrity.

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 — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

before/after photos + riprap gradation/placement record + slope-grade check + GPS

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.

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.

What counts as done

• Before photo of the eroded, undercut toe section
• Riprap gradation (rock size range) and placement record matched to the levee district's design spec
• After photo of the toe restored to design grade
• Slope-grade check confirming the repaired section matches the adjoining levee profile

Proof is measured against these, not judged by taste.

The standard this serves

Watershed Health. A watershed is everything the land pours into a stream, and the stream keeps the record. The EPA's bioassessment method reads that record through the small creatures living in the gravel: mayflies and caddisflies mean clean water, only worms and midges mean trouble. Mastery looks like a person who can wade one riffle with a net and tell you how the whole valley is doing. That skill is built sample by sample. This packet is one of them: one site, one careful count, one entry in the long record of a stream.
