Decision

I can confirm that the information requested is held by Lincolnshire County Council. I have detailed below the information that is being released to you.

1) This information will be held by the Environment Agency as lead authority for the Horncastle Flood Alleviation scheme

2) Please see note as above

3) Please see note as above

4) The Environment Agency have committed to a full and thorough review of the operation of the Horncastle Flood Relief scheme, therefore no detail is available until such time the review has taken place. Lincolnshire County Council in its role as Lead Local Flood Authority will be undertaking a Section 19 investigation (under the Flood and Water Management Act) to determine the causation and/or contributing factors that led to flooding in Horncastle following Storm Babet (as it will do for all affected locations across the county). As part of that investigation it will support Environment Agency colleagues with the review of how the Horncastle Flood relief scheme functioned during the storm event.

5) East Lindsey District Council are the Local Planning Authority so unable to make comment on this point.

6) As part of the Section 19 investigation process identified above, the maintenance and condition of drainage runs, road gullies and any relevant flood risk assets will be taking into consideration

7) Any information or action based on flood warnings received will form part of the review by the Environment Agency as well as all risk management authority partners and will be considered during the wider review of the response across Lincolnshire to the effects caused by Storm Babet

8) This will not be known until the investigation has taken place and rainfall and river level data has been analysed, but will form part of the Section 19 report.

9) No factual evidence of any failings have been made available to Lincolnshire County Council. Until the review and investigation has taken place, by both the Environment Agency, and LCC in its role as LLFA it is not appropriate to speculate and therefore unable to make any further comment at this stage.

10) Please see response to point 9 above
