ForewordThe 2013/14 and 2015/16 winter storms and flooding had significant impacts on somecommunities, businesses, infrastructure, rural areas and the environment. Evidencesuggests there could be more extremes in the weather with a changing climate leading tomore frequent and more severe flooding. During December 2015, Storms Desmond, Evaand Frank brought record breaking rainfall levels and significant flooding to some parts of theUK. Over 19,000 homes and businesses were flooded, with thousands more affected by lossof power supply and travel disruption. Existing flood defences played an essential part inprotecting thousands of homes during December with 12,500 benefitting during StormDesmond and 10,900 during Storm Eva. Support is in place for affected communities,business and the agricultural sector, along with a programme of inspections and repairs todamaged defences. These December 2015 flood events have emphasised the need to besure we have the very best possible plans in place for flood management across the wholecountry.Risk Management Authorities (RMAs) are committed to producing Flood Risk ManagementPlans (FRMPs) required by the EU Floods Directive. This FRMP is an important part ofmeeting that objective and aligns with the Defra Strategy and guiding principles of theNational Flood and Coastal Erosion Risk Management Strategy.The FRMP will provide the evidence to support decision making. The FRMP will also helppromote a greater awareness and understanding of the risks of flooding, particularly in thosecommunities at high risk, and encourage and enable householders, businesses andcommunities to take action to manage the risks. The highest priority is to reduce risk to life.Measures (actions) in individual FRMPs do not all have secured funding and are notguaranteed to be implemented. Money is allocated to all RMA measures in the same way,based on current government policy that gives the highest priority to lives and homes.This FRMP brings together for the first time measures to address all sources of flooding inThames. It is based on the most up-to-date information available at the point of publication.Measures in the FRMP are the starting point for RMA decision making and delivery. As partof on-going strategic planning additional measures will be included in RMAs and otherpartners work programmes between 2015 - 2021, although the FRMP will not be updated.FCRM strategic planning is a continuous process and informs RMA decision making and willbe the basis for the 2nd cycle FRMPs.This document has been produced in consultation with professional partners. The Flood RiskManagement Plan (FRMP) sets out the proposed measures to manage flood risk in theThames River Basin District from 2015 to 2021. This plan should be read in conjunction withthe following: Lead local flood authority (LLFA) information (for example local strategies) listed inPart B of this documentIn England, RMAs include the Environment Agency, Lead Local Flood Authorities (LLFAs),district councils (where there are no unitary authorities), internal drainage boards, watercompanies and highway authorities. These RMAs work in partnership with communities toreduce the risk of flooding. The Environment Agency would like to thank the organisationslisted on the previous pages for their contributions and feedback during consultation.Page 5 of 81

Flood risk in England will continue to change as a result of a growing population and achanging climate. There are many ways to manage flood risk including maintaining andbuilding new flood defences, building flood resilient homes and working more closely withnature to restore flood plains. Flood risk management planning is not new and RMAs havebeen able to draw on the experience of partners and earlier plans.Following the December 2015 floods, Defra announced a National Flood Resilience Review,to assess how the country can be better protected from future flooding and increasinglyextreme weather events. The review is looking at climate modelling, infrastructure, resilienceand future investment strategy. Government is also working to strengthen or establishpartnerships in the areas most flood affected to encourage a more integrated approach tomanaging risk across the whole catchment. These partnerships are consideringimprovements to flood defences, upstream options to help slow the flow and surface waterrunoff, and how planning and design of urban areas can help reduce flood risk. They arealso aiming to build stronger links between local residents, community groups and floodmanagement planning and decision making. The resulting actions from the Local FloodPartnerships in Cumbria and Yorkshire will complement the measures in the relevantFRMPs and the learning from this approach will be shared across the country. In England,the government is investing 2.3bn on 1,500 flood defence schemes between 2015-2021.Investment in flood risk management infrastructure not only reduces the risks of flooding butalso supports growth by helping to create new jobs, bringing confidence to areas previouslyaffected by floods and creating and restoring habitats.The FRMP also sets out how these proposed measures can contribute to improving theenvironment and how they support the objectives of River Basin Management Plans(RBMPs) and specifically the Thames RBMP that the Environment Agency has produced inparallel with this FRMP. Both flood risk management and river basin planning form animportant part of a collaborative and integrated approach to catchment planning for water.Building on this essential work, and in the context of the government’s 25-year environmentplan, we aim to move towards more integrated planning for the environment over the nextcycle. This will be done on a catchment basis and will draw together and integrate objectivesfor flood risk management, water management, and biodiversity, with the aim of maximisingthe multiple benefits that can be achieved.Howard DavidsonDirector Operations, South EastPage 6 of 81
