Mark San Pablo's storm drains so neighbors know they drain to Wildcat Creek

The storm drains on San Pablo's residential grid empty into Wildcat Creek untreated, and dumped motor oil or paint at one inlet reaches the creek the same day. Curb markers are proven, cheap source control. Most inlets in the older blocks are unmarked or worn blank. Standard: Contra Costa Clean Water Program inlet-marking practice; SDG 6 (Clean Water and Sanitation). Proof: Photo of each marked inlet plus location list Method (Contra Costa Clean Water Program inlet-marking practice; SDG 6 (Clean Water and Sanitation).): 1. Map ten unmarked or worn inlets on the assigned residential blocks. 2. Sweep and dry each curb face before marking. 3. Apply the 'No Dumping — Drains to Creek' marker squarely beside each inlet. 4. Log each marked inlet's cross-street. 5. Photograph every finished marker with its inlet in frame. Done when: Photo of each marked inlet plus location list

$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.

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.
