7. What must our Strategy specify?
7
a) the risk management authorities in the authority's area,
b) the flood and coastal erosion risk management functions that may be
exercised by those authorities in relation to the area,
c) the objectives for managing local flood risk
d) 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, and
i) how the strategy contributes to the achievement of wider environmental
objectives
8. Essex Objectives
8
1. To provide a clear explanation of all stakeholder’s responsibilities in flooding
issues
2. To develop a clearer understanding of the risks of flooding from surface
runoff, groundwater and ordinary watercourses and to consider how best to
communicate and share the information that becomes available
3. To define and explain the criteria by which areas at risk of flooding from
surface runoff, groundwater and ordinary watercourses are assessed and
resources are prioritised.
4. To state how risk management authorities will share information and
resources
5. To set out clear and consistent plans for risk management so that
communities and businesses can make informed decisions about the
management of the residual risk
9. Essex Objectives
9
6. To ensure that planning decisions are properly informed by flooding issues
and 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 built
environment
8. To ensure that emergency plans and responses to flood incidents are effective
and that communities are able to respond properly to flood warnings
9. To highlight where information regarding other forms of flooding can be
found

13. Flood Investigations
13
Section 19 of the Flood and Water Management Act 2010
“On becoming aware of a flood in its area, a lead local flood authority
must, to the extent that it considers it necessary or appropriate,
investigate….”
Essex Local Criteria
Where there is ambiguity surrounding the source or responsibility of
a 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.
14. 14
Receive report of flooding
1. Desktop Exercise;
• EA Susceptibility and Flood Maps for Surface Water
• Check of drainage infrastructure – Anglian Water, Thames
Water, Essex Highways, Environment Agency
• Consultation with RMA’s – any known flood history?
• Local consultation – residents and/or Parish Council
2. Site Inspection;
• Inspection of area, record asset details, photos
Flood Investigation Process
16. 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 further
recommendations – limitations on data understanding which
define solutions and provide evidence for funding bids
3) Solutions – do we progress Property Level Protection or pursue
grander physical solutions? A community decision.
Limitations
17. 17
• Scoping Exercises – to assist those who have been flooded and
define whether a published S19 FIR is required.
• Hydraulic Models – to enhance understanding of a flooding
problem to feed solution recommendation and evidence for
funding.
• Property Surveys – undertake Property Level Protection surveys
of a property to understand viability and likely cost.
Proposed Activities
18. 18
• Undertake initial assessment of flooding incident
• Liaison with other Risk Management Authorities – valuable
input
• Site inspection – valuable exercise
• Scoping exercise recommendations – full S19 FIR required,
possible solutions, raise the issue with relevant RMA,
watercourse regulation
Scoping Exercise
19. 19
• Local Studies
• Identify gaps in asset data
• Demonstrate catchment area data
• Flow rates
• Flow depths
• Critical flow paths
• Identifying the worst-case scenario
Hydraulic Models
25. Property-Level Flood Protection
25
Scheme complete for three properties in
Bowers Gifford, on-going in Rawreth and
Little Waltham.
Valuable form of flood risk management
where the cost/benefit of a capital
scheme is not justifiable.
We trust that homeowners implement
the protection measures in response to
imminent flooding.
31. 31
• Schedule 3 of the Flood and Water Management Act (not yet
enacted – although proposed for April 2014) names the County
Council the SuDS Approval Body (SAB) responsible for:
– Approving SuDS applications for all developments which have
drainage implications (to be phased in). Proposals must accord
with forthcoming National Standards
– Adopting and maintaining all SuDS systems that serve more than
one property
The Legislation
32. 32
SuDS Approval
• SAB approval will to be required for any development with
drainage implications: structure >100m2 (even Permitted
Development!)
• Phasing: initially only proposed for major development in years
1-3, 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 can
review the charges
– Fee structure is similar to planning fees
• SAB can attach conditions to and SuDS approval
SUDS Approval, Fees and Conditions
35. How we will communicate
35
The Public
• Develop informative website, signposting to relevant
organisations
• District Council website links
• Press and media
• District Council newsletter/e-newsletter
• Twitter
• Mechanism to feedback local knowledge
36. How we will communicate
36
Elected Members
• Member demonstration introducing website
• Member training about flooding
• Members given information about individual hot spots within
their area
• Briefing notes
• Mechanism to feedback local knowledge i.e SWMP steering
group.
38. 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 of
surface water flooding and agree the most cost effective way of managing surface water
flooding in the long term’.
A SWMP will investigate local flooding issues that
occurs as a result of heavy rainfall from:
• Runoff from land
• Groundwater
• Sewers/drains
• Small watercourses/ditches (Ordinary watercourses)
39. Why complete a SWMP?
• Develop a thorough understanding of surface water flood risk – taking account of
population, demographic change & urbanisation
• Develop (in partnership) a long-term action plan to manage surface water flooding that will
influence:
• 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
43. Where is Essex?
Prioritising ‘Tier 1’ areas throughout Essex based on
Environment Agency ‘blue square’ maps.
1. South Essex
2. Harlow
3. Colchester
4. Chelmsford
5. Maldon
6. Brentwood

SE SWMP Area
44. 44
There are four key phases to
a SWMP:
1. Preparation
2. Risk Assessment
3. Options
4. Implementation & Review
SWMP Process
45. • Vital to integrate & align SWMP with
other local & regional delivery plans & processes.
The Planning System – a key tool
3 key avenues that SWMP can influence
planning process:
• SFRAs
• Local Development Plan documents
• Site Allocations
• Informing planning applications
• CIL?
Fitting with other Policy and Plans
46. Fitting with other policy and plans

Hockley ‘Critical Drainage Area’ Proposed Development Site
47. Emergency Planning
• Community Risk Registers
• Multi-Agency Flood Plans
• SWMP should seek to align with
other investment activities occurring
locally:
• capital investment/improvements
• maintenance
• refurbishment of public spaces
• housing/commercial developments
Other studies and policy
