Municipal lives for parking lots (G2020)
16 municipalities in Ontario state a life for parking lots as a whole, in 16 distinct tables: 12.2–100 years, median 25. 18 rows come from capital asset policies (accounting lives, used for amortization) and 3 from asset management plans (planning lives, used to forecast replacement). They describe the system rather than this component, and none is a measured life.
Years. Each dot is one stated life and each bar a stated range; equal values stack. Hollow marks are planning lives from asset management plans; filled marks are accounting lives from policies. The dashed line is the median. Policies that copy the same table count once.
