Cities should not be built on flood plain


 If you have been following the news out of British Columbia, Canada's western most province, and also the news out of Nova Scotia, the province on Canada's Atlantic coast, you would know both these areas are receiving extreme amounts of precipitation. In B.C. one area got an average month's worth of rain in 24 hours. The Trans Canada highway has suffered washouts as have the railways linking B.C. to the rest of the country.

Although rain has not posed a serious threat in London in decades, a record breaking rainfall could wreck real havoc on certain areas of this city. Most of the city, like Springbank Park, would be safe but there are areas built on flood plain. These areas are protected by a system of dikes and a large dam in the north end of the city. But in the event of a truly extreme amount of precipitation, the Thames River could easily break free of its restraints and flood the homes built on the flood plain.

Most of Ottawa is well above the river. But there are some spots where flooding has been a problem.
