Letter to the Editor
Richard Gilbert's article on riparian areas in need of attention in Calgary focuses on engineering (soft or hard) work that is required to stabilize certain areas of the riverbank.
There is a larger story you might want to cover related to rebuilding after the flood.
I recently interviewed Frank Frigo, cited in Gilbert’s article, and two other Water Resources employees: Margaret Beeston and senior manager, Francois Bouchart.
The bigger story is that in a survey of riparian environments conducted prior to the flood
Along the Bow, the riparian environment is either unhealthy, or healthy with problems, for instance.
As I noted in my Buildex Calgary presentation, a healthy riparian environment provides invaluable ecosystem services: plants slow down the flow of water; plant roots grab soil and stabilize the riverbank; and the ribbons of land along either side of a healthy riverbank area slow down the movement of sediments and pollution.
We may have six areas in need of attention, but the reality is our riparian environments are in no way ready for the next flood.
