Lourdes Pacheco: Ten Times the Depth

The bulk Ambient Water Index goes live and Lourdes's licence turns up on 41 parcels she stood on nine of. Taking a hint from her grandmother's comal, she works out from the thin-sheet rule that a post sees about ten times the depth of the water, fills a certificate field left empty since 2041, amends rather than withdraws, writes to 32 neighbours, and wins a clip at the radius. The colour stays on a stranger's house; only her name comes off.
