Detail of a flood risk management scheme for the town will be revealed in January with the Government having set aside £25m for the project.
Since flooding in early December 2015 caused by storm Desmond, the Environment Agency has been exploring ways to better protect the area in the future.
This has included extensive appraisal work to identify the best ways to invest government funding for improved flood defences in Carlisle.
Stewart Mounsey, Environment Agency Flood Risk Manager for Cumbria, said: “Given the extent of works required in Carlisle, the city is being divided up into different phases of work.
“We hope to submit the planning application for phase one in early 2019, with an aim to start work in summer 2019.”
