The Local Planning Authority's Approach to Managing Risk
Steve Lees, Policy Design and Conservation Manager, Test Valley Borough Council
|
Development and Water
- Puting the two together nothing new
- Development often close to water
- for industry
- as a source of water
- as sewers
- means of transport
- source of power

PPS25 Development and Flood Risk (2006)
- Take flood risk into account, to direct development away from areas at higher risk
- Appraise risk, Strategic Flood Risk Assessment (SFRA) and (FRA)
- Managing risk – benefits of development outweigh the risk
- Reducing risk – management of water, layout, design
- Sequential approach, zone 1, zone 2, zone 3
- One of a number of constraints
|
|
Strategic Flood Risk Assessment
- Appointed consultants to undertake SFRA
- Told us where flooding could occur now
- Told us where flooding could occur in 2115
- Taken into account climate change
- increase in peak river flow
- increase in rainfall intensity
- sea level rise
- Flood zones 1, 2 and 3 defined

|
Assessment of Locations
- Identified preferred locations; all in zone 1
- Drainage may still be an issue
- Look to manage impact, through layout and design
|
|
Managing Impact
- Retain existing water-courses and ditches
- Create on-site storage capacity, e.g. balancing ponds
- Include flood resilient buildings
- Minimise surface water run off, soakaways porous paving
