# The Hornsea One Offshore Wind Farm Order 2014, Paragraph 18: Pre-construction monitoring and surveys

Extent: E+W+S

(1) The licence-holder must, when submitting details under condition 13(2)(a)—
(a) in relation to proposed pre-construction surveys, include methodologies and timings, and specify each survey’s objectives and explain how it will assist in either informing a useful and valid comparison with the post-construction position and/or will enable the validation or otherwise of key predictions in the Environmental Statement; and
(b) in relation to the baseline report proposals, ensure that the outcome of the agreed surveys together with existing data and reports are drawn together to present a valid statement of the pre-construction position, with any limitations, and shall make clear what post-construction comparison is intended and the justification for this being required.
(2) Subject to receipt from the licence-holder of specific proposals pursuant to this condition, it is expected that the pre-construction surveys will comprise, in outline—
(a) a survey to determine the location, extent and composition of any benthic habitats of conservation, ecological and/or economic importance in the part(s) of the offshore Order limits in which it is proposed to carry out construction works under this licence;
(b) a Phase 1 survey of the intertidal area within which it is proposed to carry out construction works;
(c) a high resolution swath bathymetric survey to include a 100% coverage and a side scan sonar survey of the part(s) of the offshore Order limits within which it is proposed to carry out construction works and disposal activities under this licence, including a 500m buffer around the site of each works; and
(d) a grab survey and particle size analysis in the part(s) of the offshore Order limits within which it is proposed to carry out dredging and disposal activities relating to Works Nos. 5 and 6 under this licence within a period not longer than 12 months prior to the dredging and disposal activities, to determine the extent of suitable herring spawning habitat within areas HU209 and HU210.
