Most precipitation events fall into the first category. However, climate change is intensifying storm severity, shifting more events into the second and third categories. One study reported increases in the intensity of 20- and 50-year return period winter precipitation events across the western United States. Another study projected rising intensity of annual maximum precipitation in Canada, with the greatest increases expected in Ontario, the Prairies, and Southern Quebec (Guinard et al., 2015)<ref>Guinard, K., Mailhot, A. and Caya, D. 2015. Projected Changes in Characteristics of Precipitation Spatial Structures over North America. International Journal of Climatology 35 (4):596–612. https://doi.org/10.1002/joc.4006 </ref>. As these storm events grow more frequent and intense, much of our infrastructure faces conditions it was never designed to withstand (Government of Ontario, 2012)<ref>Government of Ontario. 2012.

To remain effective, the design of LID features must account for these changing precipitation patterns. Go to [[Understanding rainfall statistics]] to learn more about rain event distributions.
