Document a sandy-soil gully's erosion extent at Hohlt Park, site 3, Hohlt Park, 2425 N Park St, Brenham, TX 77833 (2026-07-27)

A sandy-soil gully at this public city park has no photo record of its headcut extent, and the deep Carrizo and Sparta sand here cuts fast once a channel starts moving upslope toward the park's walking trail. Standard: USDA NRCS Soil Health assessment and restoration practice (infiltration, aggregate stability, organic matter, native root structure), applied here to Washington County's deep sandy Carrizo and Sparta soils under gully headcut and invasive-brush encroachment. SDG 15.3 land degradation neutrality. Proof: document-only stand-off photo log + width/depth measurement + GPS + ranked follow-on note Method (USDA NRCS Soil Health assessment and restoration practice (infiltration, aggregate stability, organic matter, native root structure), applied here to Washington County's deep sandy Carrizo and Sparta soils under gully headcut and invasive-brush encroachment. SDG 15.3 land degradation neutrality.): 1. 1. From an accessible trail or park edge, photograph the sandy-soil gully's headcut and extent without stepping into the eroding channel. 2. 2. Measure the gully's approximate width and depth from a stable stance using a tape measure, and photograph the measurement. 3. 3. Note whether the headcut is advancing toward the walking trail or a park structure. 4. 4. Record a ranked follow-on note naming the reach for the erosion-control crew. Done when: document-only stand-off photo log + width/depth measurement + GPS + ranked follow-on 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.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: USDA-NRCS soil-health in-situ assessment

Bring

• soil auger or trowel
• infiltration ring + measured water + timer
• penetrometer (if compaction in scope)
• clean bucket
• sample bags + labels
• gloves
• GPS phone
• camera

Steps

1. 1. Navigate to the plot; record GPS; sketch the sampling layout.
2. 2. Photograph each sampling station.
3. 3. Run the infiltration ring; record time to infiltrate 1 inch.
4. 4. Assess aggregate stability and note visible organic matter, roots, and biology.
5. 5. If compaction is in scope, record penetrometer resistance by depth.
6. 6. Collect 0-15 cm cores if a lab subsample is specified; bag, label, complete COC.
7. 7. Enter all measurements with units + depth, GPS, photos into the proof record; sign.

If it does not match the plan

• Infiltration > 30 min/inch or high penetrometer resistance -> flag compaction; recommend cover crop / reduced traffic.
• Very low organic matter / no visible biology -> flag degraded; recommend amendment plan.

What counts as done

• Infiltration time recorded
• Aggregate stability + organic-matter observation recorded
• Each in-scope measurement recorded with units and depth
• GPS waypoint + station photos + site sketch

Proof is measured against these, not judged by taste.
