Hornsea Project Three Offshore Wind Farm

Received 20 July 2018
From Historic England


It is important to note that on 1st April 2015 Historic England was vested (retaining the formal title of the Historic Buildings and Monuments Commission for England) and is now the government service championing England’s heritage and giving expert, constructive advice.

There is potential for this development to impact upon the historic environment, and that without mitigation this impact will be significant in relation to some receptors.

We are aware that the application includes a comprehensive Environmental Statement and that some amendments have been made to the ES since our letter of September 2017 in relation to the PEIR stage. A detailed discussion of our comments and the developer’s responses is provided in Table 5.4, we have however noted that a number of specific points have not been fully considered and we will address these in our written submission.

Likewise we have previously raised concerns in relation to the impact of the Mangreen substation on the significance of a number of designated heritage assets through development within their setting. We are pleased that a specific historic environment visualisations chapter has been produced (see Vol. 6 Annex 5.7) to work alongside the Historic Environment Chapter of the ES. Using this additional material we have been able to confirm that there are only limited views from some of the designated heritage assets we have previously mentioned. The visualisations have however also indicated that the development would erode the rural setting of a number of other highly graded heritage assets, which would result in a high degree of harm to their significance. In particular the three Grade II* listed buildings located close to the substation (Gowthorpe Manor House and Barn and Mangreen Hall). We also have concerns about the impact of the development upon the Grade II* registered park and garden and Grade II* listed church at Intwood, and on a number of Grade II listed buildings such as Keswick Hall and the local Conservation Areas which lie to the north of the development. We will explore these issues further in our written representation with reference to these assets.

The application includes an outline Offshore WSI which sets out how the proposed project might mitigate against impact to the historic environment. We will therefore require the draft DCO to include provision for delivery of a project specific WSI (should consent be granted).

The WSI must enable the implementation of appropriate mitigation measures to avoid and reduce the impact from the development on the historic environment, and develop appropriate methodologies for further investigations conducted within the project area, which will be used to inform the development of mitigation measures. This will inform the delivery of the project in a timely way, by taking these matters into consideration prior to the commencement of construction activities. Therefore, the WSI must be produced and agreed pre-commencement – i.e. before the commencement of pre-construction surveys.
