East Anglia ONE Offshore Windfarm - National Infrastructure Planning

117,000. Port of Felixstowe is the largest container port in the UK and one of
the largest in Europe. The area is crossed by several major roads serving
Ipswich and the ports.
The Suffolk Landscape Typology describes the countryside between Ipswich
and the coast as primarily a rich agricultural landscape of estate farmlands
(Ancient estate farmlands, Rolling estate farmlands, Plateau estate farmlands,
Estate sandlands and Rolling estate sandlands) intersected by Coastal levels,
Saltmarsh and Intertidal flats.
1.5 POTENTIAL ENVIRONMENTAL EFFECTS
The potential environmental effects of the proposed infrastructure are
summarised below.
It must be noted that there is presently a considerable level of uncertainty
regarding the precise nature of the connection infrastructure required for East
Anglia ONE. Detailed routeing studies are proposed and preferred routeing
options will be discussed with the relevant authorities at an early stage. A
Scoping Document will then be provided giving more specific baseline
information, identifying the surveys required, and describing the potential
environmental effects to be assessed within the Environmental Impact
Assessment.
At this initial stage, the following caveats therefore apply.
1: The baseline information given in this document is extremely high level.
2: Discussions with consultees will be required after the submission of this
document in order to define the geographical extent and intensity of primary
data collection. This information will be presented in detail in a subsequent
scoping request.
3: Ultimately, the identification, and modelling, of potential environmental
effects will be based on a “Rochdale Envelope” approach with regard to the
size, location and layout of project infrastructure, and the construction,
operation and decommissioning methodologies. Generic effects only are
therefore identified at this time.
4: The environmental effects identified in this document assume that the
onshore export cable infrastructure will be undergrounded.
Potential Physical Environmental Effects
Suspended Sediments
� Increased suspended sediment levels during construction and
decommissioning of offshore infrastructure.
