The Poole Bay Partnership
Poolebay.net was first published in response to the high level of public interest
in the major beach replenishment projects of 2005-
Other sources of local coastal information
Poole’s beaches following the replenishment project 2005/06 was wide enough to function as a coast protection structure, and controls were required to ensure it remained that way for as long as possible.
In 2008 planning permission was granted to Poole Council’s Coastal & Drainage team
for the construction of five new rock groynes at Branksome Chine and Branksome Dene
Chine, each measuring between 45m -
The contract was awarded to Dean & Dyball (now Balfour Beatty); construction work commenced 24th November and was completed on 5th May 2009.
Some 20,000 tonnes of rock were delivered to the beach by low-
New Safe Swimming Zones will be created between the new groynes using yellow markers. These RNLI approved zones have been successful at Sandbanks.
The choice of rock groynes for this project followed more than three years of detailed investigations and analysis by HR Wallingford.
Engineers from Italy, Holland and New Zealand were involved in the first stage of
the study which considered more than 20 options for beach control structures. A final
report recommended four options for detailed consideration -
This project at Poole is a move away from the traditional coastal protection scheme in that a post project appraisal and programme of beach monitoring is being funded by Defra as part of the overall scheme, and will compare outcomes with computer modelling by HR Wallingford. The results will inform Environment Agency research, and help the refinement of beach plan shape models in the future.
During this project large excavations were made at the back of the beach for construction of ramps. There foundations were taken to below the level of sand before beach replenishment (2006/07).
Ramps allow access across the beach for, for instance, the beach rake and tractor. They also provide access from the promenade to the beach and the groyne walkways, and allow easier access for the less able and those using mobility scooter or wheelchairs, buggies and prams. The size of the excavation is due to the working area required to provide the long 1:20 slope that complies with Disability Discrimination Act (DDA) regulations.
During construction sand from the excavation was placed seaward to give protection to the workforce and the working area. Once construction work was complete the sand was replaced in the excavation trench. Current beach levels mean that the majority of the ramps will be covered by sand but the extent of the ramps will ensure they can be utilised if / when beach levels drop.
