Introduction This technical paper details an environmental statement undertaken by AP Heritage Ltd to determine the potential for effects on archaeology and cultural heritage assets as an environmental factor by a proposed development at Northern Gateway (former Corus Garden City site), Flintshire (centred on NGR SJ 32297 69670). This takes the form of a desk-based assessment of the outlined application site and its immediate vicinity, and aims to draw on existing information in order to identify the resource in terms of the baseline conditions, and the resultant potential impacts by the development. In this way, the significance of the impact is assessed and relevant recommendations can be made for further work from which a mitigation strategy can be formed. The area of land subject to the proposals is hereinafter referred to in this document as the ‘Scheme Area’. The assessment was carried out by Alison Plummer (AP Heritage Ltd) on behalf of Ian Miller (Senior Project Manager at OA North). Thanks are due to Mark Walters, Planning Archaeologist at the Clwyd/Powys Archaeological Trust (CPAT), for his advice and support. Thanks are also due to Peter DeFigueiredo for providing information relating to the listed buildings within the Scheme Area. In the case of this application, we have not undertaken a detailed Screening or Scoping Opinion Request to the Council. On this basis, Spawforths has sought to confirm with the Council by letter the information to be provided in the Environmental Statement, in accordance with Part 4 (13) of the EIA Regulations, to ensure the scope of the technical chapters and the methodology for assessing the significance of effects is robust. To enable the Council to consider this Spawforths enclosed the following plans and information: • A Location Plan identifying “The Land”; • A description of the nature and purpose of the development including a Character Area Plan; • Topic/Technical Chapters of the ES based on the issues to be assessed; Methodology for the Assessment of Significant Effects in accordance with EIA Regulations; • The cumulative impacts to be considered. The Council subsequently confirmed that they accepted this approach and methodology including the range of environmental issues against which the proposals should be assessed as part of the Environmental Impact Assessment process; a copy of the Council letter confirming this is attached at Appendix 13 of the Part 1 Report of this ES. Pochin Rosemund (Deeside) Ltd, Northern Gateway (former Corus Garden City site) 4 AP Heritage Ltd Whilst a Scoping Opinion was not requested, the Development Control Archaeologist at CPAT has been consulted extensively during the Environmental Impact Assessment and cultural heritage assessments undertaken. Topics and issues discussed covered the heritage assets, include both above and below ground (known and potential) archaeological assets, historic buildings and structures, and historic gardens and landscape. A summary of the consultation process is provided in Section 3 . Pochin Rosemund (Deeside) Ltd, Northern Gateway (former Corus Garden City site) 5 AP Heritage Ltd 2.
