Build a bioswale at the Globeville Landing Park stormwater inlet

Runoff from the surrounding streets hits the South Platte at this park's inlet untreated; a planted bioswale filters it before it reaches the river. 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 drainage path and photograph the inlet area as found. 2. Hand-dig the swale channel to the planned grade and cross-section, kept shallow (under 12 inches). 3. Amend the soil and plant it with deep-rooted native, water-tolerant species along the channel. 4. Mulch the planting and run a hose test to confirm the swale conveys and infiltrates flow. 5. Photograph the finished, planted swale and log the plant list. Done when: before/after photos + hose-test video + plant list + GPS

$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.
