Dorset County Council (DCC) has announced that Parsons Brinckerhoff has developed a design to stabilise the landslide that has kept the C13 at Dinah’s Hollow closed since April 2014 – but environmental issues may further delay the work.
Remediation will use a combination of soil nailing, rock netting and concrete retaining walls but efforts have been made to ensure the character of the ancient Holloway on the road between Blandford and Shaftesbury is retained.
Although design work is complete, DCC has said that the timescales for the work have yet to be finalised and a number of statutory processes, including tree preservation orders and environmental impact assessments, may delay the start of the work
DCC has said that vegetation and some trees will need to be removed to allow the work to go ahead but work cannot be undertaken between March and August due to the risk of disturbing wildlife.
“Getting the timing right is going to be very tricky,” said DCC cabinet member for environment and economy Peter Finney. “Our discussions are still on going with various third parties to resolve any final issues. As soon as these negotiations are successfully completed the operation plan can be put in place, then there will be clarity with the timescales. Until that point is reached no definite dates can be finalised.”
