What is Floodway Expansion?
The Red River Floodway Expansion Project will increase flood protection for residents of the City of Winnipeg, East St. Paul and West St. Paul. Once completed, the project will protect more than 450,000 Manitobans, over 140,000 homes, over 8,000 businesses, and prevent more than $12 billion in damages to the provincial econo my in the event of a 1-in-700 year flood.
By increasing the capacity of the floodway channel from 1,700 cubic metres (60,000 cubic feet) of water per second to 4,000 cubic metres (140,000 cubic feet) per second, floodway expansion will increase the level of protection from floods with a 1-in-90 to a 1-in-700 year probability of recurrence.
The project will result in a major expansion of
the existing floodway protection system including modifications
to the Floodway Channel, replacement and upgrade of 6 bridge
crossings, improvements to the Inlet and Outlet control works,
modifications to utilities and services and the expansion of
the West Dike. Approximately 27 million cubic metres (35 million
cu. yds) of earth will be moved in the process. The expansion
is expected to take place over 5 years (2005-2010) with channel
widening complete by Spring 2009 and bridge work carrying over
until Spring 2010.
