Flood Risk Assessment Tesco Supermarket, Swaffham
3 PLANNING POLICY CONTEXT
3.1 National Policy
In accordance with PPS25, the site proposals are classified as being
within Flood Zone 1 and have low probability of flooding (less that an
average 0.1% or 1-in-100 year annual probability of flooding from river
or tidal sources). All types of development are appropriate in this Flood
Zone; therefore the proposals pass the Sequential Test outlined within
PPS 25.
A full review of PPS 25 is reproduced for reference in Appendix E.
3.2 Local Planning Policy
3.2.1 Local Plan
The Breckland District Local Plan was adopted in September 1999. It
was originally prepared to plan for the period up to mid 2006.
Breckland Council is currently preparing a Local Development
Framework that has replaced the majority of the Breckland District
Local Plan. A number of policies have been saved from the Local Plan,
although none relate to Flood Risk.
3.2.2 Strategic Flood Risk Assessment
Breckland Council has commissioned a detailed Strategic Flood Risk
Assessment (SFRA) which was produced in October 2007 and updated
in February 2008.
This report sets out Breckland Council s‟ strategic planning in relation
to areas at risk of flooding as required by obligations under planning
guidance (PPS 25).
Various background information regarding flooding in the Swaffham
area is provided in the SFRA as summarised below:
“The town of Swaffham is at least 4 km from any Main River,
and well outside the Extreme Flood Outline. It is therefore
considered not to be at flood risk from this source. In addition,
there are no watercourses marked on the Ordnance Survey
maps in the Swaffham area.
“A site visit has shown that Swaffham is generally higher than
the area surrounding it and there are no watercourses in the
valleys surrounding the town, or surface water collecting in low
areas.
