Drainage and Flood Risk


From its earliest days TAG has been concerned with the risk of flooding resulting from the geographical position of Thornton, being on a peninsula with the Irish sea a mile to the west and the tidal Wyre estuary forming its eastern boundary. Large scale development in recent years has led to decreasing natural drainage and increasing volumes of stormwater draining into a drainage system of finite capacity. Inadequate maintenance and protection of infrastructure that was installed to mitigate flood risk is an ongoing concern.


Thornton Flood Action Group


Thornton was an area of Wyre without a local Flood Group so members of TAG volunteered to fulfil the role and have completed the Thornton Flood Risk Summary Sheet which forms part of the Wyre Flood Plan.

The Flood Risk Summary Sheet contains detailed information about Thornton comprising of local Environment Agency flood maps, information regarding evacuation routes, vulnerable infrastructure for example pumping stations, vulnerable populations, emergency control points, road closure procedures and flooding history.


The Thornton FLAG can be contacted for general concerns via the Facebook page or by contacting the secretary@thorntonactiongroup.co.uk. To report flood related problems contact Wyre Council

During Office hours – 891000 (Council Contact centre)

Out of Office hours - 895116 (Duty Officer)



Flood Wardens in Thornton: There are currently six volunteer Flood wardens in Thornton who spend time familiarising themselves with all areas of Thornton with regard to the location of dykes, for example Royles Brook at King George’s field and beyond, natural drainage systems which are throughout Thornton, the location of local infrastructure and their condition for example debris gates located on Royles brook, weeds in water courses etc., Thornton FLAG also comments on Planning Applications where flooding from surface water could be an issue. Thornton is designated by the Environment Agency as being in Flood Zones 1,2 and 3 – with 3 being the highest risk of flooding. The majority of Thornton is in Flood Zone 3.

Further information can be found on the Facebook page – Thornton Flood Action Group.


Wyre Flood Forum: The FLAG wardens attend the Flood Forum at Wyre Council which takes place on a regular basis. All local Flood Action Groups attend this meeting alongside the Environment Agency, United Utilities, LCC, Wyre Council officers and other interested parties. Thornton FLAG raises concerns at this meeting about issues directly affecting residents in Thornton and is constantly campaigning to ensure that the relevant authorities maintain the infrastructure which mitigates flood risk.


The Environment Agency ( EA ), which in 2010 sent circulars to many Thornton properties entitled “Floods operate in your area”, state that over 5 million people in England and Wales live and work in properties that are at risk of flooding from rivers or the sea. The EA wbsite provides a lot of flood information and advice, including the Flood Risk Maps which are used by insurers in assessing household and business premiums,

Planners and Developers: A great many of the flooding problems in Britain have arisen from development which has taken place in inappropriate locations and/or with inadequate flood mitigation measures. Planning Authorities are required to follow the National Planning Policy Framework which was republished in July 2018. Thornton FLAG and TAG comment where appropriate on Planning applications which raise concerns regarding the possibility of flooding.


What's Happening Now? Over the years TAG have assisted residents with a number of flood related issues and raised concerns with Planners about increased flood risk resulting from a number of proposed developments. Thornton FLAG has now taken on this role and, along with TAG, attended the 2018 Enquiry into the Draft Local Plan for Wyre and given evidence to the Government Inspector to highlight the issues and concerns around some of the proposed development sites within the Plan.
