Hayling Island - Scottish and Southern Energy

Hayling Island - Scottish and Southern Energy

When Scottish and Southern Energy were drawing up plans for a replacement 33KV cable route supplying Hayling Island in Hampshire, they commissioned us to carry out an environmental appraisal of the scheme in this sensitive location. The proposed route crossed the Langstone Harbour SSSI, Chichester Harbour SSSI, Solent Maritime SAC, Chichester and Langstone SPA, the Chichester and Langstone Harbours Ramsar sites and the locally designated East of Pyecroft's Meadow SINC.

The proposals combined trenching and directional drill installation methods, with some sections of the route to be installed as an overhead line. The cable route was located within largely agricultural land and also crossed an estuary.
W
e assessed the potential impacts on landscape, ecology and cultural heritage both at the route option and preferred route stages of the project. Although there was no requirement for an EIA, we carried out breeding bird surveys, a detailed botanical survey and salinity testing. We developed a mitigation strategy in close consultation with Natural England and the County ecologist, and held an archaeological watching brief during trenching and excavation works.
