West London Dyke

West London Dyke

History

19th c.: Dyke built in the West London area Area prone to flooding Construction: material from street

sweeping and soil from excavation

1914: Reconstruction, installed current facing

History

1947: formation of UTRCA Upper Thames River Conservation

Authority (URTCA)

Results: City of London owns dykes’ structure

and undertakes minor maintenance UTRCA undertakes major maintenance

Purpose of Dyke

Thames River susceptible to serious flooding

Number of major flood control projects: Three dams (Fanshawe, Wildwood, Pittock) Many dykes

Projects built to: Reduce risk of loss of life Reduce risk of property damage

July 2000 Flood, Fanshawe Dam

Purpose

Flood management structures protect: More than 1000 homes from flooding

However… the West London Dyke is damaged and needs replacement

Damage to Dyke

“It was concluded that a significant portion of the 350 m section of the dyke [from Oxford St bridge to Riverside Dr. bridge – Harris Park to Forks] has come to the end of its useful life and needs to be replaced rather than repaired” (West London Dyke report)
