Flimby is a village located on the West Coast of Cumbria between Workington and Maryport with a population of approximately 2000 people. Inland from the coast, the land rises steeply for approximately three kilometres, reaching the hill crest where the sources of the watercourses can be found. Flimby has a long record of flooding from Penny Gill and Flimby Gill (Barrel Arch), which flow through culverts under the village and railway embankment before discharging out at sea, and is also vulnerable to surface water flooding. Flimby was badly affected by flooding in December 2015 when 100 properties were inundated and roads became impassable.
The Environment Agency undertook an appraisal to identify options for reducing flood risk to the village. As the catchment is small and responds rapidly to rainfall, natural flood management measures to ‘slow the flow’ and store water within the catchment could also be very effective at reducing flood risk.
