Swale Desk Field notes on swales and yard drainage. One desk, three numbers.
Season Fall storm season in much of the US: Sep–Nov. Photos of a wet yard are most useful taken during or just after rain, with a ruler in the puddle.

What to send for a correction

  • The page URL.
  • The exact figure or sentence in question.
  • The source that says otherwise — a code chapter, manual page, or manufacturer sheet, with a link or photo.

Corrections that arrive without a source are read and weighed, but a stamp only moves when the desk can open the document itself.

What to send about your yard

  1. Grade of the wet area — measured, not eyeballed: how to measure.
  2. Percolation rate — one presoaked hole: how to test.
  3. Catchment — roof planes and yard area feeding the spot: how to count.
  4. Photos: the wet spot during rain, the downspouts, and the uphill view.

Three numbers and four photos beat a paragraph of adjectives every time.

Response time

Within a week, usually sooner in storm season. If a question is about a foundation, footing, or retaining wall, the reply will say one thing: find a local engineer. That is the refuse list working.
