雨后走一圈，记录各处积水退水的时间：上海市浦东新区前滩友城公园 | Walk the site after rain and record how long each pond takes to draw down: Qiantan Sister City Park, Pudong New Area, Shanghai.

一处海绵设施是否还在工作，最诚实的判断是雨停以后水多久退干。走一趟固定路线，把每个积水点的位置、深度和退水时间记下来，管养单位就有了排序的依据。这一项只记录，不动手。现场：上海市浦东新区前滩友城公园。新建社区旁的公园，下凹绿地与社区园圃是设计中就有的公共设施。 | English: The honest test of whether a sponge facility still works is how long the water sits after the rain stops. One fixed route, recording each ponding point's location, depth and drawdown time, gives the maintenance unit something to order its work by. This rung records only, it changes nothing. Site: Qiantan Sister City Park, Pudong New Area, Shanghai. A park beside a new residential district, where sunken green areas and community plots were public fixtures from the design stage.

$120 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

路线图 + 各点水深与观察时刻 + 24小时后仍积水点位列表 + GPS点位 | route map + depth and time at each point + list of points still ponding at twenty-four hours + GPS pins

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.

Steps

1. 1. 雨停后两小时内出发，沿固定路线走完全部下凹绿地、植草沟和透水铺装。 | Set out within two hours of the rain stopping and walk the fixed route past every sunken green, swale and permeable surface.
2. 2. 每个积水点拍照，量最深处水深，记录GPS点位和观察时刻。 | Photograph each ponding point, measure the deepest water, and record the GPS pin and the time observed.
3. 3. 雨停后第六小时和第二十四小时各回访一次同样的点位。 | Return to the same points six hours and twenty-four hours after the rain stopped.
4. 4. 按二十四小时后仍有积水的点位单独列表，这是最需要处理的。 | List separately every point still holding water at twenty-four hours, which is the set most in need of attention.
5. 5. 把路线图、水深与时刻表交给管养单位，不做任何清理或改动。 | Hand the route map, depths and timings to the maintenance unit, doing no clearing and changing nothing.

What counts as done

• 雨停后两小时内的积水点照片 | Photo of each ponding point within two hours of the rain stopping
• 同一点位第二十四小时的照片 | Photo of the same point at twenty-four hours
• 各点最大水深(厘米)与观察时刻 | Greatest depth in centimetres and time observed at each point
• 二十四小时后仍有积水的点位列表 | List of points still holding water at twenty-four hours

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.
