Depave an invited Iron Triangle yard strip and open the ground again

Decades of paved-over yards send every drop of rain — and everything it picks up — straight to the bay, while summer heat radiates off the same slabs. Breaking out an invited strip of unused concrete and opening the soil is the first physical rung of the block's stormwater ladder. Standard: Depave-practice guidance; Contra Costa clean-water program yard-scale GSI. LBC Water petal, SDG 6/11. Proof: before/after + square-footage log + 811 note Method (Depave-practice guidance; Contra Costa clean-water program yard-scale GSI. LBC Water petal, SDG 6/11.): 1. Confirm the strip with the owner and verify with 811 marks that no utilities cross it; photograph before. 2. Break the slab with sledge/pry hand tools; stack rubble for reuse or haul-off. 3. Fork and loosen the exposed soil; remove trash layers found beneath. 4. Photograph the opened ground from matching vantage; log square footage opened. Done when: before/after + square-footage log + 811 note

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

before/after + square-footage log + 811 note

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.
