Parameter
Mitigation measures embedded into the project design
field boundaries where practical. This wouldminimise the loss of land under agricultural use. This design also optimises access to fields to maintain access for farm vehicles. Where land area is separated by the works, access for farm vehicles would be maintained where practicable, in consultation with individual landowners and occupiers. Where necessary, crossing points would be agreed prior to construction.
Code of Construction Practice
The preparation and implementation of a CoCP throughout the construction works to include:
The separate storage of topsoil and excavated materials, to prevent mixing of subsoil and topsoil, thus improving reinstatement.
Minimising excavation volumes and disturbance to the surrounding areas, together with the replacement of any soils inadvertently disturbed during excavations in general accordance with their original structure and location.
The setting of vehicular speeds along the construction access routes to minimise soil trafficking.
Soils that cannot be reinstated will be removed to a suitability licenced facility.
An Outline CoCP for East Anglia THREE will be submitted in support of the DCO application.
Onshore cable route Project design – routeing
Project design – HDD Construction
Construction – land drainage
Initial cable routeing and site selection to avoid key sensitive land uses e.g. development land, urban land, residential land, major utilities.
HDD to avoid impacts upon sensitive features where practicable.
Providing temporary means of access to severed fields for animals, vehicles andmachinery.
Appropriate planning and timing of works to reduce conflicts.
Land drainage systems would be maintained during construction and reinstated on completion. Temporary cut-off drains would be installed parallel to the trench-line, before the start of construction, to intercept soil, surface and groundwater before it reaches the trench. These field drains would discharge into local drainage ditches through silt traps, as appropriate, to minimise sediment release. In addition:
• • Following construction, field drainage systems and ditches
would be fully reinstated where possible in consultation with landowners / occupiers;
Cable system buried at a depth to allow the continuation of
current agricultural practices; and •
Construction – utilities
In the event of any problems during post-construction monitoring further remediation work would be undertaken.
Potentially affected utility providers would be contacted and the location of existing services would be accurately identified on the ground prior to construction. EATL would undertake utility crossings in
