As the Lead Local Flood Authority (LLFA) we have a duty to investigate all large scale floods and must report back to councillors and all the other agencies involved.
Flooding took place around 8 November, and then again on 14 November. Autumn 2019 was the wettest since records began in England. Around 325 residential properties and 59 commercial properties in Derbyshire all flooded internally.
Our Cabinet Member for Highways, Transport and Infrastructure, Councillor Simon Spencer said:
“This report sets out which parts of the county flooded and makes recommendations for everyone involved.
“Being flooded, whether it is of your home or business, can be devastating, so we will be learning all we can from the November floods, and doing all we can to prevent similar floods taking place in the future.”
The majority of the flooding on 7 and 8 November, was as a direct result of fluvial flooding. Fluvial flooding is where a watercourse floods as it cannot contain the water flowing along within its banks and so it floods the land around it.
The River Derwent was the largest river that caused the most flooding issues on 7 and 8 November and across the county some rivers were the highest for 60 years
The water levels in the main rivers throughout the county remained high for about a week, which is why when a second band of exceptionally heavy rain arrived on 14 November in the south of Derbyshire further flooding occurred.
Other parts of the county, including Matlock, also flooded on the 14 November because the river levels were still very high, following the floods the week before. The drains were full, so the surface water had no other place to go other than Matlock town centre.
The report sets out a series of actions that it recommends that ourselves and partner agencies should undertake.
