Heritage Assessment at Trevarthian Farm

The desk-based research and impact assessment were undertaken in accordance with the relevant guidance and in line with the SWARCH HIA methodology3. The site was visited on the 15th of January 2024 by B. Morris and F. Balmond. The location of the proposed development was inspected, and the adjacent heritage assets visited. Photographs of the site of the proposed array were taken to and from the heritage assets are included in this report. In terms of the potential impact on heritage assets in the wider area via harm to their setting, most of the designated heritage assets in the wider area are located at such a distance to minimise the impact of the proposed site, or else the contribution of setting to overall significance is less important than other factors. The landscape context of many of these buildings and monuments is such that they would be partly or wholly insulated from the effects of the proposed PV site by a combination of local blocking, and the topography. The only assets where a level of impact above negligible is likely to occur are Trevarthian Farm (GII), the Church of St Hilary (GI), and the Cornwall and West Devon Mining Landscape World Heritage Site. In the latter two instances, the level of harm is likely to be much less than the magnitude of effect would indicate, given the relatively small visual effect in landscape terms. Accordingly, the overall impact of the scheme is adjudged to be no higher than minor adverse.
