to be considered by the District Council


New information and perspectives are appearing on the controversial plans to halt erosion from the sea at Sidmouth:

The council has now announced that it will be considering more information on erosion.

Although, interestingly, the predictions in this report assume that no efforts will be made to reduce erosion:

“A report on University of Plymouth research, estimating future rates of coastal erosion in East Devon over the next 100 years, will be considered by the council’s Strategic Planning Committee on Tuesday 20th October.:

It does not, however, take into account the protection that East Devon Beach Management Plan schemes currently in design will deliver.

The study suggests that parts of the coastline at Seaton, areas either side of Branscombe and East of the River Sid at Sidmouth may see more erosion than previously predicted.

There are some questions concerning the compilation of the report:

  • Has there been liaison between Plymouth University and EDDC’s planning department?
  • How have the numbers on erosion for the next 20, 50 and 100 years at Pennington Point been determined?
  • What are the differences between the numbers in the Plymouth University report and those in the BMP?

Meanwhile, the FAQs on the District Council’s website have been updated this week:
