Following Tuesday's storm sewer collapse and the chaos that ensued, Cumberland councillor Stephen Blais decided to ask city staff for a timeline of everything that happened, following that inspection last summer when engineers noticed the pipe had deteriorated and needed to be re-lined. Here's what he got today:

Blais says if the Rideau Valley Conservation Authority hadn't forbidden that work from commencing before July 1, the job would have been higher on the priority list and the pipe could have been re-lined much sooner. Theoretically, that would have prevented the collapse, the sink hole, and the traffic nightmare that ensued. In other words, if it weren't for a few tadpoles, east-end residents might not be sitting in gridlock tight now.
