Signals / Event / Building permits stream
in Des Plaines, IL·counted·1 all time
A permit for installing or modifying watering equipment, typically covering sprinklers, irrigation pipes, or lawn systems.
Counted, not streamed: Irrigation Permit has no time series, so it is read as a footprint across places. All-time count by city.
Things that happen: permits, collisions, crimes, inspections. All-time counts.
