After the onslaught of hurricane Cynthia on France's coastline in 2010, the Conseil Général de la Charente Maritime (Charente Maritime departmental council) decided to provide technical support to local authorities to protect homes in sensitive areas.
On 28 February 2010 the coastline in the department of Charente-Maritime suffered under a violent storm. Damage was caused right along the coast, several sea defences were destroyed or damaged and numerous business-activity and housing areas were flooded.
Under the ORSEC emergency response plan and exceptional storm programme, emergency works, classed as "Level 1 & 2", were undertaken in some fifty sectors to seal or repair structures.
With a view to implementing "Level 3" works, the Conseil Général de la Charente Maritime decided to provide technical support to local authorities concerned by areas that were particularly sensitive to flooding, with the aim of protecting homes or facilities where daytime activities takes place.
Egis provided services in several areas: preliminary studies to determine sea defence means, hazard study, cost analysis, studies for the project and assistance to the client in making works contracts, checking of detailed working drawings, and other associated services.
