Historic Landscape Impact Assessment, Monmouthshire
The proposal was for two three bladed wind turbines of up to 100m tip-height and associated infrastructure located to the south of the M4 motorway within an area of low-lying agricultural pasture land extending down to the coast of the Severn Estuary.
A staged process of quantified assessment was undertaken to determine the Historic Landscape implications of the proposed wind turbine scheme and the extent to which the development may affect a Historic Landscape Character Area (HLCA).

In Brief
Key Points
- Assessment of proposed wind turbine development to inform a decision as to whether Natural Resources Wales should seek a ‘Call In’
- Utilised the Assessment of the Significance of the Impact of Development on Historic Landscape (ASIDOHL) assessment process for use in connection with the Register of Landscapes of Historic Interest in Wales
- Located within the Historic Landscape Character Area (HLCA) of Caldicot Moor, forming a component of the Gwent Levels Historic Landscape (HL) designated as being of Outstanding Historic Interest
Summary
The proposal was for two three bladed wind turbines of up to 100m tip-height and associated infrastructure located to the south of the M4 motorway within an area of low-lying agricultural pasture land extending down to the coast of the Severn Estuary.
A staged process of quantified assessment was undertaken to determine the Historic Landscape implications of the proposed wind turbine scheme and the extent to which the development may affect a Historic Landscape Character Area (HLCA).
Results
The assessment determined the Historic Landscape implications of the proposed wind turbine scheme and provided a professional view as to whether the scheme raised planning issues of more than local importance, consistent with the advice set out in Planning Policy Wales.
