Shoreline Management Plans

• Defra High Level Target

• Coastal defence decisions

• Sustainable defences

• Natural environment

• Human environment

• Built environment

• Action Plans

Objectives

To set out risks to our coast and estuaries

To identify preferred policies to manage these

To discourage inappropriate development

To meet nature conservation legislation

Current Situation

Tidal Floodplain

without sea level rise

Erosion risk information

• Complement flood map

• Clear information to public

• Evidence for planning

• Best science

• Coastal engagement

Evidence – Coast Monitoring

The need for coastal adaptationHistory of flooding

‘No Active Intervention’ or ‘Managed Realignment’

Defra assessing how communities can best adapt to increasing risks

‘Big Society’ encourages communal solutions

Somerset Pathfinder

• Led by Somerset County Council on behalf of partner organisations

Lessons Learnt

• Little experience of a severe flood event

• Scenarios are useful tools, but consider how they are portrayed

• Encouraging good attendance at drop-in sessions:

– Publicity

– Accessibility

– Format

– Provide answers to queries

Successes

• A dedicated Project Officer

• Practical, close-knit community

• A series of drop-in sessions

• Website

• E-game

• Non-technical outputs & stepped

development of Adaptation Action

Plan

• Porlock Weir Flood Action Group is

being formed

‘Big Society’ and Localism

Reduced sea defence funding can incentivise communities to seek a communal solution

Local knowledge is essential

Parish Council play an important role in mobilising community

Social Media

Strategic flood defence solution required to allow planned growth at Bridgwater, given extent of flood risk.

Preferred Solution is a Surge Barrier known as ‘The Parrett Barrier’ - estimated cost £24.6m

Need for policy approach to deal with PPS25 requirements for new development to be safe for its lifetime taking climate change into account

Draft Supplementary Planning Document (SPD) was completed in 3 months – EA/SDC. – delivers a ‘roof tax ‘ on all new development

Being used to secure estimated £3.2m contribution from a strategic mixed use scheme at North East Bridgwater.

The Planning Background

Contributions will be held by the Sedgemoor District Council;

A mechanism will be in place to ring fence funds for the Parrett Barrier;

SDC will produce an annual statement of total contributions secured;

SDC/EA will jointly commission a review of the scheme cost estimates at ‘key project milestones’, available alternative sources of funding, and the strength of the business case for delivery of the scheme;

Contributions will be index linked;
