Presentation Summary2 Introduction to Lead Local Flood Authorities - What must we do? The Local Flood Risk Management Strategy - How are we doing it?• Flood Investigations• Watercourse Regulation• Sustainable Drainage Approval Body (?)• Communications Surface Water Management Plans Detailed Assessment and Local Feasibility Studies
Why a Lead Local Flood Authorities?3
Where do we fit in?4‘Local’ Flood Risk Surface Water Runoff Groundwater Ordinary Watercourses
What must we do as LLFAs?5 Produce the Preliminary Flood Risk Assessment by 22 Dec 2011 Develop, maintain, apply and monitor a Local Flood RiskManagement Strategy for their area Flood Hazard Maps published by 22 Dec 2013 Flood Risk Management Plans by 22 Dec 2015 Duty to Investigate Flood Incidents when necessary or appropriate Maintain an Asset Register for significant flood risk assets Duty to Co-operate with other Flood Risk Management Authorities Sustainable Drainage Approval Body (April 2014?)
The Local Flood RiskManagement Strategyfor Essex
What must our Strategy specify?7a) the risk management authorities in the authoritys area,b) the flood and coastal erosion risk management functions that may beexercised by those authorities in relation to the area,c) the objectives for managing local flood riskd) the measures proposed to achieve those objectives,e) how and when the measures are expected to be implemented,f) the costs and benefits of those measures, and how they are to be paid for,g) the assessment of local flood risk for the purpose of the strategy,h) how and when the strategy is to be reviewed, andi) how the strategy contributes to the achievement of wider environmentalobjectives
Essex Objectives81. To provide a clear explanation of all stakeholder’s responsibilities in floodingissues2. To develop a clearer understanding of the risks of flooding from surfacerunoff, groundwater and ordinary watercourses and to consider how best tocommunicate and share the information that becomes available3. To define and explain the criteria by which areas at risk of flooding fromsurface runoff, groundwater and ordinary watercourses are assessed andresources are prioritised.4. To state how risk management authorities will share information andresources5. To set out clear and consistent plans for risk management so thatcommunities and businesses can make informed decisions about themanagement of the residual risk
Essex Objectives96. To ensure that planning decisions are properly informed by flooding issuesand the impact future planning may have.7. To encourage innovative management of flood and coastal erosion risks,taking account of the needs of communities and the natural and builtenvironment8. To ensure that emergency plans and responses to flood incidents are effectiveand that communities are able to respond properly to flood warnings9. To highlight where information regarding other forms of flooding can befound

Flood Investigation Reports
Flood Investigations13Section 19 of the Flood and Water Management Act 2010 “On becoming aware of a flood in its area, a lead local flood authoritymust, to the extent that it considers it necessary or appropriate,investigate….”Essex Local Criteria Where there is ambiguity surrounding the source or responsibility ofa flood incident; AND Internal flooding of one property on more than one occasion; OR Internal flooding of five properties during one flood incident; OR Where there is a risk to life as a result of flooding.
14Receive report of flooding1. Desktop Exercise;• EA Susceptibility and Flood Maps for Surface Water• Check of drainage infrastructure – Anglian Water, ThamesWater, Essex Highways, Environment Agency• Consultation with RMA’s – any known flood history?• Local consultation – residents and/or Parish Council2. Site Inspection;• Inspection of area, record asset details, photosFlood Investigation Process
15• www.essex.gov.uk/floodingThe Published Reports
16• Limitation of Flood Investigations;1) If incident doesn’t meet Essex criteria do we ignore it?2) Outcomes of an investigation – legal obligation and furtherrecommendations – limitations on data understanding whichdefine solutions and provide evidence for funding bids3) Solutions – do we progress Property Level Protection or pursuegrander physical solutions? A community decision.Limitations
17• Scoping Exercises – to assist those who have been flooded anddefine whether a published S19 FIR is required.• Hydraulic Models – to enhance understanding of a floodingproblem to feed solution recommendation and evidence forfunding.• Property Surveys – undertake Property Level Protection surveysof a property to understand viability and likely cost.Proposed Activities
18• Undertake initial assessment of flooding incident• Liaison with other Risk Management Authorities – valuableinput• Site inspection – valuable exercise• Scoping exercise recommendations – full S19 FIR required,possible solutions, raise the issue with relevant RMA,watercourse regulationScoping Exercise
19• Local Studies• Identify gaps in asset data• Demonstrate catchment area data• Flow rates• Flow depths• Critical flow paths• Identifying the worst-case scenarioHydraulic Models
Property-Level Flood Protection25 Scheme complete for three properties inBowers Gifford, on-going in Rawreth andLittle Waltham. Valuable form of flood risk managementwhere the cost/benefit of a capitalscheme is not justifiable. We trust that homeowners implementthe protection measures in response toimminent flooding.
Land Drainage Act Changes27
Sustainable DrainageApproval Body(SAB)
30What are SUDS?
31• Schedule 3 of the Flood and Water Management Act (not yetenacted – although proposed for April 2014) names the CountyCouncil the SuDS Approval Body (SAB) responsible for:– Approving SuDS applications for all developments which havedrainage implications (to be phased in). Proposals must accordwith forthcoming National Standards– Adopting and maintaining all SuDS systems that serve more thanone propertyThe Legislation
32SuDS Approval• SAB approval will to be required for any development withdrainage implications: structure >100m2 (even PermittedDevelopment!)• Phasing: initially only proposed for major development in years1-3, needed for all development year 4 onwards.• There will be an application fee payable:– These are set by Defra for the first 3 years after which we canreview the charges– Fee structure is similar to planning fees• SAB can attach conditions to and SuDS approvalSUDS Approval, Fees and Conditions
SUDS Design and Adoption Guide33
How we will communicate35The Public• Develop informative website, signposting to relevantorganisations• District Council website links• Press and media• District Council newsletter/e-newsletter• Twitter• Mechanism to feedback local knowledge
How we will communicate36Elected Members• Member demonstration introducing website• Member training about flooding• Members given information about individual hot spots withintheir area• Briefing notes• Mechanism to feedback local knowledge i.e SWMP steeringgroup.
Surface WaterManagement Plans(SWMPs)
What is a SWMP?• the primary vehicle to manage surface water flooding in England• be developed in areas of high surface water flood risk‘Study undertaken in consultation with key partners to understand the cause and effects ofsurface water flooding and agree the most cost effective way of managing surface waterflooding in the long term’.A SWMP will investigate local flooding issues thatoccurs as a result of heavy rainfall from:• Runoff from land• Groundwater• Sewers/drains• Small watercourses/ditches (Ordinary watercourses)
Why complete a SWMP?• Develop a thorough understanding of surface water flood risk – taking account ofpopulation, demographic change & urbanisation• Develop (in partnership) a long-term action plan to manage surface water flooding that willinfluence:• capital investment• maintenance (i.e. highways/water companies)• emergency planning• land-use planning/future developments (LDF)• Engage with public and raise awareness and understanding of surface water flooding• Identify flood risk assets

• Vital to integrate & align SWMP withother local & regional delivery plans & processes.The Planning System – a key tool3 key avenues that SWMP can influenceplanning process:• SFRAs• Local Development Plan documents• Site Allocations• Informing planning applications• CIL?Fitting with other Policy and Plans
Fitting with other policy and plans46Hockley ‘Critical Drainage Area’ Proposed Development Site
Emergency Planning• Community Risk Registers• Multi-Agency Flood Plans• SWMP should seek to align withother investment activities occurringlocally:• capital investment/improvements• maintenance• refurbishment of public spaces• housing/commercial developmentsOther studies and policy
