This layer is a high level Vulnerability Assessment of Historic Assets along the Northern Ireland coast. It was created as part of the Baseline Study and Gap Analysis of Coastal Erosion Risk Management in Northern Ireland Study which was prepared by Amey Consulting with HR Wallingford for the Department for Infrastructure (DfI) and the Department of Agriculture, Environment and Rural Affairs (DAERA) in 2018. The Report is an important first step in identifying areas that may be vulnerable to coastal erosion and has identified a number of key issues for consideration in determining the way forward. The full report is found at https://www.infrastructure-ni.gov.uk/publications/baseline-study-and-gap-analysis-coastal-erosion-risk-management-ni As part of the study, a high-level preliminary vulnerability assessment of coastal erosion along the Northern Ireland coast was undertaken utilising data which was available at the time. The high-level assessment consisted of two stages: an Erosion Risk Appraisal (this layer) and a Vulnerability Assessment. The Vulnerability Assessment compared areas of high/medium/low erosion risk against physical asset value, historic asset value and natural asset value also at high/medium/low value. These layers are available on the ODNI Portal.
