Update on work to date
Since we last met we have:
- Updated objectives
- Firmed up on timescales
- Completed assessment of current and future flood risk
- Completed draft consequence assessment
- Held workshop with Tier 2 stakeholders
- Begun work on the SEA
- Further developed plans for main phase of public
consultation
Updated objectives:
As amended following SG1:
-
Improve our knowledge and understanding of local flood risk in
Hampshire
-
Develop strategy, policy and a LFRMS action plan to manage these
risks, providing balanced social and environmental benefits for the
economic investment
-
Work in partnership with other flood risk management authorities
to deliver the strategy and action plan
-
Maintain, and improve where necessary, local flood risk
management infrastructure and systems to reduce risk
Updated objectives:
-
Ensure that local planning authorities take full account of flood
risk when allocating land and considering permitting development
(by avoiding development in inappropriate locations and
minimising flood risk wherever possible)
-
Engage with community groups to increase public awareness and
reporting of flooding and promote appropriate individual and
community level planning and action.
-
Improve and support community level flood response and
recovery.
-
Identify national, regional and local funding mechanisms to deliver
flood risk management interventions.
LFRMS timescales
- 15 year timeframe, to tie in with NPPF and 15 year horizon
for Local Plans
- Within this there will be short medium and longer term
targets
- There will be a programmed review of the LFRMS after 6
years
- Action plan to be reviewed annually
Tier 2 workshop
Shared assessment with stakeholders
•
Communication between stakeholders and the steering group emphasised
as important.
•
Clarification over areas of responsibility and management requested.
•
The importance of planning regulations was highlighted.
•
Utilising the Pitt report in developing the project recommended.
•
Nuisance flooding highlighted as a large problem.
•
Relative importance of groundwater flooding in Hampshire
•
Map analysis would be more effective if more of the public were involved
(potentially using the internet).
•
Adding catchments to maps was recommended by stakeholders.
•
Stakeholders would like to see key terms (flooding, floodplain,
groundwater flooding) defined.
•
Fire and Rescue services call out data could be used within the project.
Assessment of current and future flood risk: recap
- Combine national scale data from EA, with regional scale
data from other providers
- Build on PFRA assessment
- Sit alongside SWMP where they exist
- Single consistent assessment of local flood risk
- Feed into future SWMP programme
- Balanced assessment of consequence and probability
Available data: recap
• Incident data
• HCC incident data (drainage tool v5.xls) & supporting GIS layers
• Water company flood incident data (DG5 register)
• Thames Water
• Southern Water
• Wessex Water
• Groundwater flooding incident data from 2001 report and EA Defra
report on groundwater flooding
• Model or simulated data
• EA flood maps
• EA surface water maps (AStSWF, FMfSW)
Methodology
• The number of residential properties which flood internally
• The number of non residential properties (such as shops and
factories) which flood internally
• The number of properties which are critical infrastructure which
floods internally (such as schools, hospitals, electricity sub
stations)
• The length of motorway and A-roads which flood

The Emerging LFRMS
Potential measures and policies
Early identification of measures
• Groupings – source, pathway, receptor
• Type – structural, non structural
• Theme – flow reduction, source control, diversion, policy,
education and resilience, conveyance, storage, maintenance,
protection/permanent defences, exceedence
Early identification of measures
Next Steps
Strategy development, SEA and consultation
Next steps
• Finalisation of SEA Scoping Report
• Consultation on SEA Scoping Report
• Further refinement of the flood risk assessment
• Gathering info on funding sources
• Gathering info on planned/committed schemes
• Defining potential policy approaches
• Continue to draw up a ‘long list’ of potential schemes
• Iterative process of SEA and LFRMS development
• Short listing of schemes in priority areas
• Identifying a costed programme of works to address flood issues
• Consultation on draft LFRMS and SEA Environmental Report
• Finalisation of the LFRMS and SEA Environmental Report
Consultation on draft strategy…
• The draft LFRMS will be available for public consultation in the
autumn
• We will be holding 3 or 4 drop in sessions/exhibitions for people to
find out more and ask questions
• The document will be also be available online and there will be an
online questionnaire
• Please take the time to comment and encourage others to also get
involved
Consultation on draft strategy…
•
We intend to publicise the consultation via
• County press
• Local press
• Parish magazines
• Twitter/facebook
• Community websites
• Posters
• An email newsletter
• Letters and emails
• Please let us know if you can think of any other ways we can
spread the word
