Build a bioswale that catches street runoff before it leaves San Antonio, TX.

Street runoff in San Antonio carries the first flush straight to the Edwards Aquifer recharge zone and the San Antonio River and takes the recharge with it. On a public strip or right-of-way with the authority's written permission and an honored 811 locate, cut and shape a shallow vegetated swale on the contour, set a stone inlet where the sheet flow already arrives, amend the soil for infiltration, plant regionally native species that tolerate both flood and drought, and set the overflow so a big storm leaves safely. The swale is measured by how fast it draws down, not by how it looks the day it is planted.

Pay

$300 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 — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

written permission, 811 ticket, GPS line, before and after photos, cross section with length and depth, species list, and a drawdown time after the first storm

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.

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.

What counts as done

• The public authority's written permission and the 811 locate ticket number, both dated before any digging
• A GPS line of the swale with before and after photos from the same vantage, and its length, top width and depth
• Species list with counts, all regionally native, and the seed or nursery source
• The drawdown time measured after the first storm or the first fill, with the date and the depth it started from

Proof is measured against these, not judged by taste.

The standard this serves

Green Stormwater Infrastructure. Green stormwater infrastructure is the city's way of handling rain the way a meadow does: rain gardens, planted swales, and permeable pavement that let a storm soak in instead of surging down a pipe. The EPA's inspection standard keeps these systems honest, because a neglected rain garden quietly stops working while still looking like a garden. Mastery is the inspector's eye: reading inlets, overflow, plants, and soil in a single practiced pass. This packet is one such inspection, one basin checked and one record filed, which is precisely how a thousand basins stay alive.
