At a progress meeting held
23rd March 2009 it was announced that 2,363 Christchurch properties are
at risk over the next 100 years (Poole 4,500 and Bournemouth 545). Maps
and up to date comments are available on the website
www.channelcoast.org.
In producing the new plan, which is scheduled to be complete later this
year, many local factors will be taken into account including the tidal
limit of our rivers and the amount of residual water in Christchurch
Harbour at certain tides. Information was primarily provided by
Professor Andy Bradbury who produced a Flood Risk Map of the coastline.
It was emphasised that the team were still in the information gathering
stage but the following points were made.
-
The local areas most affected are Christchurch and Poole Bays.
- The original life of the current coastal defences was 50yrs, which
in some cases has already expired.
- There is some erosion throughout the bay but we do benefit from
beach replenishment from other areas such as Poole and Bournemouth,
which results in material being washed up at Mudeford and Hengistbury
Head. The beach studies are ongoing
- The recharge of beaches at Bournemouth protects the cliffs.
- Stanpit Marsh and other SSSI sites will naturally relocate. As the
water levels rise, higher ground will become the new salt marsh sites.
