## Settlement

Why this grade: Reports, not coyotes: one animal seen by a whole block can bring many reports. Shown, not settled on.
What it costs to move: Cheap in small numbers. A report is a phone call or a web form.
When the source is late: A month prints three days after it ends. If 311 posts nothing for the month, it stays open. A month 311 never posts is void.
Precision: Whole reports with service code CIAC, by created date, Chicago time as the city records it.
