Dublin Page 2 Moore Group October 2019 Non Technical Summary MOORE GROUP was commissioned to complete a cultural heritage impact assessment of the potential impact of a proposed residential development on lands at Windmill, Porterstown, Dublin 15. This study aims to assess the baseline archaeological, architectural and cultural heritage environment (hereafter referred to as cultural heritage environment or cultural heritage resource), to evaluate the potential or likely impacts that the proposed development will have on this environment and, where appropriate, to suggest mitigation measures to ameliorate potential impacts. Following on from this, the residual impact that the proposed scheme will have on the baseline cultural heritage resource is identified and evaluated. The assessment found that the proposed development does not directly impact on the Zone/s of Notification for any archaeological sites or monuments nor does it impact on any Protected Structure or NIAH site. The site up until recent years was undeveloped agricultural land with quarry pits to the south along the Royal Canal. Since circa 2008 the site has been stripped of its top soil and used to store spoil dumps of builder’s fill. Based on the condition of the site archaeological testing or monitoring would not be practical or worthwhile. It is recommended that work proceeds with no further mitigation. The above recommendations are subject to the approval of the National Monuments Service (Department of Culture, Heritage and the Gaeltacht) and Fingal Council. 19073 Windmill, Porterstown, Co.
