AN UPDATED booklet has been released to give guidance to Chiswell residents in the event of another storm breaching Portland s sea defences. The Dorset Coast Forum, in partnership with the Environment Agency and Dorset Council, has released an updated version of the ‘Storms and Coastal Defences at Chiswell’ booklet after huge waves led to flooding and the closure of Portland Road in January. The booklet was produced to help inform the community on what to do in a storm event, explain how the coastal defences work and what may happen in the future. The overtopping of the sea defences and flooding in Chiswell which occurred on January 30 are to be expected when there are long period swell waves which are particularly high in energy.
