Municipal accounting lives for parking lots (G2020)

13 municipal policies from Ontario set a life for parking lots as a whole, from 13 distinct tables: 18–80 years, median 25. These are amortization periods chosen for accounting, not measured lives, and they describe the system rather than this component.

Years. Each dot is one stated life and each bar a stated range; equal values stack. The dashed line is the median. Policies that copy the same table count once.
