Survey low-town Oroville storm drain inlets ahead of Feather River winter storms (2026-07-18)

Oroville's low-lying blocks near the Feather River sit downstream of the dam that made national news in February 2017 when the main spillway failed and 188,000 people evacuated the basin, and the city's storm drains still clog fast with leaf litter and trash each winter storm season. A block-by-block inlet survey before the rains hit tells the next crew exactly which drains need clearing first. Standard: EPA municipal storm drain inspection method + SDG 11 resilient cities Proof: Photo log of each inlet with a clear/blocked rating Method (EPA municipal storm drain inspection method + SDG 11 resilient cities): 1. Walk a defined block of curbside storm drain inlets before the first fall storm. 2. Photograph each inlet grate and note whether it is clear, partly blocked, or fully blocked. 3. Record the street address or nearest cross street for each inlet. 4. Rank the blocked inlets by severity for the next clearing pass. 5. Note any inlet with standing water already pooling nearby. 6. Submit the ranked list with photos to the next crew. Done when: Photo log of each inlet with a clear/blocked rating

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 30–75 minutes. Method of record: EPA green-infrastructure inspection (bioretention / bioswale / permeable pavement function + maintenance)

Bring

• measuring tape
• GPS phone
• camera
• trowel / probe
• data sheet
• gloves

Steps

1. 1. Locate the GI asset; record GPS; identify the type (rain garden / bioswale / permeable pavement / tree filter).
2. 2. Photograph the asset, its inlet, and its outlet/overflow.
3. 3. Check the inlet and outlet for blockage (sediment, trash, mulch) and note whether flow can enter/leave freely.
4. 4. Check for standing water and estimate whether it drains within the design window (typically <24-48h after rain); probe media if dry.
5. 5. Assess vegetation/media condition and estimate sediment/trash accumulation depth.
6. 6. Note erosion, bypass, or structural damage and list the maintenance needed.
7. 7. Enter asset type, condition, inlet/outlet status, drainage observation, sediment level, maintenance needs, GPS, photos; sign.

If it does not match the plan

• Standing water persists > 48h after rain -> flag failed infiltration (clogged media) for rehab.
• Inlet or outlet blocked -> flag for cleaning; the asset isn't capturing runoff.
• Erosion, undercutting, or flow bypassing the asset -> flag for repair.
• Documentation only — no digging out media or altering structures.

What counts as done

• Asset type + overall condition recorded
• Inlet + outlet clear/blocked status recorded
• Standing-water / infiltration observation recorded
• Sediment/trash level + maintenance recommendations + GPS + photos

Proof is measured against these, not judged by taste.
