Marlow’s Community Flood Plan

This finalised plan has been devised after reviewing the effects of flooding events, with the help of residents’ experiences and feedback. With the input from other Flood responding Agencies, including; Thames Water, Wycombe District Council, Bucks County Council, Fire Services and The Environmental Agency we have been able to produce a plan which will coordinate a response, ensuring residents are informed and supported in the case of a flood event. 

We are still on the look out for voluntary Flood Wardens. If you live within the Marlow area and are interested in being part of this proactive working group we would love to hear from you. 

Advice on Flooding from the Environment Agency

“If you are unfortunate enough to experience property flooding it is important that you report this to the Environment Agency via their Incident Hotline: 0800 807060 (Freephone, 24 hour service). The Environment Agency use information on flooded properties to check the accuracy of its flood warning service and to make improvements to this service wherever possible. We do not share information on which properties have flooded with insurance companies.

If you haven’t done so already, you can sign up to receive free flood warnings by calling Floodline (0845 988 1188) or via our website: . By visiting our website you can also find out what actions you can take to prepare in advance of flooding to reduce the impact on your home and family.

Marlow Flood Alleviation Scheme 

Work continuing at Gossmore November 2019: Work is now almost complete and the fencing is due to come down this month and the park be completely open to residents. Footabll pitches should be back in use for Spring 2020.

Marlow has a dedicated page covering the alleviation scheme, which will be kept up to date by the Environment Agency.

The Marlow Flood Alleviation Scheme will reduce flood risk to 287 properties in Marlow from a combination of fluvial and groundwater flooding.

The Environment Agency has implemented the planning permission for the scheme. This took place in accordance with the planning conditions which required us to start highway work at Gossmore Lane next to the railway line. We completed this work in August 2015.

We are currently undertaking two approaches with the scheme. Whilst we continue delivering the existing scheme we will review the standard of protection and requirements for compensatory storage provided by the scheme.

Work on the existing scheme includes:

     – Undertaking ecological surveys at Pound Lane and Lower Pound Lane – these will continue into autumn

     – Finalising the existing design – for example detailing the groundwater pumping system.

     – Discussing with landowners requirements of constructing the scheme.

Review the planning proposal 16/06946/FUL for Gossmore Recreation Ground here.

The review of the scheme will include:

Our flood modelling on the lower part of the Thames is being updated as part of the work to develop other schemes. Whilst we continue to develop the scheme, we will be using this latest modelling to check the standard of protection and details for compensatory storage provided by the scheme.

The review should be complete by September 2016. Under both approaches we envisage construction of the scheme to begin in spring 2017 subject to all legal and land requirements being finalised.
