This DBA aims to achieve the following: � To identify and understand the historic environment baseline of the proposed development area and the study area. � Identify archaeological and historic assets within, and near, the application area that are potentially sensitive to change. � Assess the significance of historic assets which may be affected by the construction of the proposed development, including through changes to setting. � Contribute to the research framework for the archaeology of the Isles of Scilly by providing new data about the historical environment, informing research strategies, and contributing to a broader understanding of the historic environment. � Provide an indication of the archaeological potential within the proposed development area. The Site lies within the Isles of Scilly Conservation Area. In 1975, all five islands were designated as a conservation area. The proposed development will remove some land from the agricultural hinterland, replacing it with built development and hardstanding. However, the Site is not considered to contribute to the significance or understanding of the conservation area. The surrounding vegetation bordering the Site should be kept if possible in order to retain the agricultural character of the surrounding landscape. It is therefore considered that this will result in no harm to the significance of the conservation area as per paragraphs 208 of the NPPF. The next closest asset comprises the Ennor Castle Scheduled Monument, which is recorded c. 120m east of the Site. It is anticipated that there will be a neutral impact upon the significance of the scheduled monument, through changes to setting. Should the scale and elevation of the new WWTP remain below the surrounding tree line, views to the east of the castle will not be obstructed and vice versa. It is therefore considered that this will result in no harm to the significance of the scheduled monument as per paragraphs 208 of the NPPF. There are two non-designated heritage assets recorded within the Site. These comprise two medieval field boundaries. These assets were not encountered during a programme of archaeological trial trenching which took place within the Site in 2010. This evaluation recorded a cobbled surface, possible drain and sherds of pottery and glass, all of which dated from the 17th - 20th century and are of low archaeological interest. Following this evaluation, there was further disturbance within the Site which is shown on aerial imagery in 2011 and is associated with the construction of the Five Islands Academy to the west of the Site. The 2010 fieldwork report also concluded that no further fieldwork was required within the Site. It is therefore considered that any archaeological remains within the Site, should they be present, will likely have been removed and/or truncated. It is recommended that further consultation be undertaken with the Cornwall Archaeological Unit to ascertain if further archaeological investigation or mitigation is required.
