News shorts: Should large paved areas pay more for stormwater runoff?

This chart from the City of Ottawa shows who owns paved properties (impermeable to rainfall) in Ottawa. The orange shared infrastructure is almost all roads. On the private property, the "benefit to each property owner from the stormwater system is equal to the amount of stormwater run-off that enters the system."

The City of Ottawa is currently undertaking a water rate structure review, which could mean a change in water bills, particularly for non-residential customers.

It’s considering changing stormwater fees to charge more for non-residential properties with a high percentage of “impervious surfaces” – like parking lots. It says it can now use aerial imagery to determine this percentage.

The city is also considering changing the ratio on your water bill between fixed charges and water usage (currently 20/80) so that your water conservation efforts would have less effect on your bill.
