(VOLUME 2) 7 CULTURAL HERITAGE 7.1 EXECUTIVE SUMMARY An Environmental Impact Assessment Report (EIAR) was compiled on the direct and indirect impacts of the proposed Cross Tay Link Road (CTLR) Project on heritage assets. This assessment has been undertaken in accordance with national legislation, national and local government policies, and takes cognisance of the guidance documents of the Chartered Institute for Archaeologists. In order to complete the assessment, Historic Environment Scotland (HES) and Perth and Kinross Heritage Trust (PKHT) were consulted with regard to heritage assets within their respective remits. The assessment includes a consideration of all direct impacts on all known designated and non- designated cultural heritage assets within the boundary of the proposed CTLR Project. The baseline for the area of the proposed CTLR Project incorporates a study of heritage assets within the area 250m from the centre line of the proposed CTLR Project. It also includes the associated infrastructure, temporary access roads and compensatory planting, also with a 250m buffer, to understand the development of the historic environment and to create a predictive model of the probability for potential buried archaeological remains to exist. In addition to a range of existing sources of data, extensive geophysical surveys and trial trenching were undertaken over the unwooded parts of the proposed CTLR Project. This has greatly strengthened this assessment. This study concluded that within the proposed CTLR Project there is moderate potential for unknown prehistoric sites. The potential for unknown assets across the proposed CTLR Project is low, with the exception of the following where the potential for assets of the specified periods is moderate: • prehistoric assets between the eastern bank of the River Tay and Stormontfield Road; • post-medieval assets between Stormontfield Road and the A93; • prehistoric Roman and early medieval assets in the Blairhall area of compensatory planting; and • prehistoric assets in the Cairnton area of compensatory planting. The predicted significant construction effects consist of adverse effects of moderate significance on the multivallate fort at Broxy Kennels (heritage asset Sweco No. 4 in the gazetteer compiled for the assessment), resulting from the removal of a large part of the asset. This can be mitigated to very slight through a programme of archaeological recording. The predicted significant operational effects comprise effects of substantial significance on the setting of parts
