The site
The Shoreham Adur tidal walls scheme covers a wide area. The site office and visitor centre are located in Beach Green car park. Satellite compounds will be set up to serve specific reaches and will be in place for the duration of the works.
The method of installation will vary depending on the location and type of defence. Further details on the method of installation is on the individual reach pages.
Methods
There are a number of methods for installing sheet piling, with varying levels of vibration. The Environment Agency will use the method most appropriate to the area where it is working to minimise any risk of damage to property. The Environment agency will be carrying out pre- and post-condition surveys before starting works, and monitoring vibration levels during installation.
Disturbance
If, following construction, you believe the works have caused damage to your property, there is a compensation process. Please contact the Environment Agency at shorehamwestbank@environment-agency.gov.uk for more information.
The works are likely to cause some disturbance. The hours of work are set out in a condition of planning. These conditions will be enforceable by Adur District Council. Core working hours are 8am to 6pm Monday to Friday and from 9am to 1pm Saturday. The contractor has permission to carry out specific activities outside of core hours, such as tide affected activities.
It is likely that there will be temporary local diversions or traffic controls in some areas. To allow you to plan around the diversions, the Environment Agency will make sure that as much notice is given as possible.
The Environment Agency will also need to transport large machinery and materials around Shoreham. Again, they will try and minimise disruption to the local community as far as possible.
Health and safety
It should be noted that the working area will be a construction site. Therefore the Environment Agency has to comply with health and safety legislation, which means some footpaths or cycle paths will have to be closed temporarily. In areas where works are located, pedestrians and cyclists will be diverted around the works for safety. The length of the diversion and the duration will be minimised as much as possible. The Environment Agency will aim to minimise closures, but in places with public rights of way, it will need to divert the paths. Details of footpath closures and diversions.
Access to properties
Access to properties along the river may be impacted by Environment Agency work, but wherever possible it will minimise this disruption. Some properties may only have pedestrian access while construction works are happening nearby. You may not be able to park your car outside your house, and you may need to use specific access routes that are safe. The Environment Agency will talk to those individuals who are impacted about access arrangements and how long these will need to be in place in advance of them starting work.
Trees and wildlife
It is likely some trees and bushes will need to be removed or cut back so the team have enough space to work. Some may also need to be removed if construction causes irreparable damage, for safety reasons.
Removal or cutting back will be carried out by tree surgeons. Where possible they will be replaced, although it should be noted that the Environment Agency may not be able to replace trees or bushes with ones of the same maturity. Trees and bushes will not be replanted on the new defences to ensure they remain structurally intact.
There will be some areas where the team will use new planting to screen or enhance the appearance of the defence.
Construction activities have been planned to minimise the impact on local wildlife. Reptiles have been relocated from working areas, to designated safe areas in advance of construction. The Environment Agency will also aim to time their works to minimise disturbance to migratory fish and birds.
