Stencil the storm drains that feed the Dominguez Channel on Carson's residential blocks

Carson's street drains run to the Dominguez Channel, the urban waterway that carries the watershed's trash and runoff to the harbor. Marked inlets measurably reduce dumping of washwater, oil, and litter, and most Carson blocks have never been stenciled. Standard: LA County MS4 storm-drain marking practice; SDG 6 (Clean Water and Sanitation). Proof: Per-inlet marker photos plus block map Method (LA County MS4 storm-drain marking practice; SDG 6 (Clean Water and Sanitation).): 1. Map every inlet on the assigned blocks on a simple sheet. 2. Sweep and dry the curb face at each inlet. 3. Apply the drains-to-channel stencil or adhesive marker per kit instructions. 4. Let each marker set cleanly. 5. Photograph each marker close-up plus street context with date and GPS. Done when: Per-inlet marker photos plus block map

$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

Per-inlet marker photos plus block map

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 30–75 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.
