New excavation permits in Chicago — week of March 9, 2020
Every matching building permit the City of Chicago issued from 2020-03-09 to 2020-03-15, read from the City’s own dataset ydr8-5enu and re-read daily. Filter: Any permit whose work description mentions excavation, caissons, or shoring. 245 in the year to 2026-07-01 — a thin trade, so quiet weeks are common.
