Question:
What does the first phase involve?
Answer:

The first phase (October 2015 to April 2020) involves the replacement of 30 groynes along the coast from Southbourne to Hengistbury Head. Beach replenishment has taken place between Bournemouth and Boscombe Piers and to the east of Boscombe Pier. We are replacing 320,000 cubic metres of sand during autumn/winter 2015/16.

The second and third phases (up to year 2032) will replace the remaining 29 groynes along the seafront from Southbourne to Alum Chine. There will also be a further two beach replenishment operations. The locations of the future beach replenishments will be determined nearer the time. We continually monitor beach levels and will assess which areas need attention.
