William Morrison Supermarkets PLC (the client) will submit a planning application for a new foodstore at the Atlantic Street Retail Park, Broadheath, Atrincham, WA14 4RW. In order to validate the application, Trafford Council requires a heritage statement (Policy R1 of Trafford Core Strategy), as guidance states that both full and outline planning applications require a heritage statement for applications that might affect heritage assets1. Two aspects of the proposal may be covered within the Validation Checklist: development affecting the setting of a listed building, and development on sites that are of archaeological interest. The purpose of this study is to identify which heritage assets might be affected by the proposed application, and to provide an initial assessment of their heritage significance and the potential impact of the proposed scheme. The Heritage Statement will be used by the Local Planning Authority (LPA) to ensure that sufficient preliminary assessment has been undertaken to allow validation of the application. Based on the results from the heritage assessment, the LPA might decide no further action will be necessary before determination of the application, but conversely it is possible that the initial findings presented here would benefit from more detailed surveys during the application consultation period.
