Airport Road Flood Upgrades

pre-construction

The Town of Hay River, NT is highly susceptible to springtime flooding due to annual ice jamming and the effects of freshet in the Hay River as it flows north into Great Slave Lake. The river bifurcates, and in its western channel, there has been a consistent history of flooding. The recent 2022 caused extensive damage to numerous homes and businesses as well as a ballpark. The project will raise the level of Airport Road which runs adjacent to the west channel as well as install appropriate water drainage infrastructure. The road that most impacted will be asphalted to make it resistant to flood erosion as well as banked with impermeable materials. The access road to the town’s water plant will also be elevated to ensure access during a flood period.These efforts will provide a return on investment of $11.78 of flood damage loss avoided for every $1 invested over the life of the asset.
