INTRODUCTION Non‐designated heritage assets are buildings, structures, sites, places and This document explores the impact of the development localities identified landscapes that have been identified as having a degree of significance within the Revised Draft Riverside Sunderland Supplementary Planning meriting consideration in planning decisions because of their heritage Document (SPD). It has been prepared in response to comments received interest but that are not formally designated. Some assets are known, from Historic England in regard to Heritage Impact Assessments and the others are unknown but the potential for them to exist is known. Draft Riverside Sunderland SPD. This Heritage Impact Assessment seeks to provide robust and defensible The historic environment covers a wide range of assets including buildings, evidence of the potential risk of development within the localities identified structures, archaeological remains, landscape features and historic open in the emerging Riverside SPD and also to inform the emerging Allocations spaces. These are collectively known as heritage assets. Heritage assets are and Designations Plan (A&D Plan) with regard to the significance of heritage identified as being either designated or non‐ designated. Designated assets and their settings. In addition to identifying the potential risks to heritage assets include: heritage of development, and whether or not development can be justified, World Heritage Sites; the study seeks to provide guidance on the opportunities and strategies for Listed Buildings; mitigating any impact on the significance of heritage assets and to consider Registered Parks and Gardens; opportunities for positive enhancement or for an asset to be better Scheduled Monuments; revealed. The Heritage Impact Assessments also make suggestions about Registered Battlefields; further work required and future monitoring. Conservation Areas; and, Protected Wrecks. It is intended to provide a proportionate understanding of the significance and sensitivity to change of heritage assets both within sites and those that would be affected by changes to their settings as a consequence of © 2020 Sunderland City Council: HIA Methodology Page 3 of 19 development. This understanding will be based on evidence gathered through a high level desk top research and site visits. It is acknowledged that further primary evidence and research may yield more significance which is not detailed in this assessment but may be better understood through the development management process. The findings of this study will provide further safeguards for the historic environment within the Riverside SPD and supporting text for site allocations within the emerging A&D Plan where appropriate or potential significant effects on the historic environment have been identified. © 2020 Sunderland City Council: HIA Methodology Page 4 of 19 2. THE FRAMEWORK set out in the saved Unitary Development Plan (UDP) Alteration No.2 The National Planning Policy Framework (NPPF) requires Local Planning policies and the adopted Core Strategy and Development Plan (CSDP) (2015‐ Authorities to meet objectively assessed needs (OAN) for housing, business 2033). It will also inform the emerging A&D Plan, which proposes to replace and other development, with sufficient flexibility to adapt to change. The the relevant policies contained within UDP Alteration No.2 and the CSDP strategy adopted by Sunderland City Council is to establish Riverside with a new Riverside Sunderland allocation. Sunderland as a successful business location, a popular place to live and a focal point for civic, cultural and community life. The purpose of this Heritage Impact Assessment (HIA) is to inform the Riverside SPD and A&D Plan by demonstrating how the historic environment The key elements of Riverside Sunderland will include: has been considered in the site selection process and to assess the likely • a new central business district; impact on heritage assets, both designated and non‐designated, and • new city centre residential neighbourhoods; whether those impacts could be mitigated.
