Build a bioretention planter feeding Weir Gulch

Street runoff along Morrison Road drains straight into Weir Gulch untreated; a curb-fed bioretention planter filters it before it reaches the channel. Standard: EPA green-infrastructure inspection — bioretention/bioswale/permeable-pavement function + maintenance; SDG 6.3/11.5. Proof: before/after photos + hose-test video + plant list + GPS Method (EPA green-infrastructure inspection — bioretention/bioswale/permeable-pavement function + maintenance; SDG 6.3/11.5.): 1. Confirm the curb-cut/drainage path and photograph the site as found. 2. Hand-dig the planter box to the planned depth (kept shallow, under 12 inches) and set the underdrain/overflow per the design. 3. Backfill with bioretention soil media and plant with deep-rooted, water-tolerant natives. 4. Mulch and run a hose test to confirm inflow, filtration and overflow function. 5. Photograph the finished, planted planter and log the plant list. Done when: before/after photos + hose-test video + plant list + GPS

Pay

$130 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

before/after photos + hose-test video + plant list + 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. 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.
