The assessment should be read in conjunction with the photomontages prepared for the scheme, and the landscape report also prepared by Jane McCorkell Landscapes. 1.1 Study Methodology This assessment is based on the following guidelines -: The EPA Draft ‘Guidelines on the information to be contained in Environmental Impact Assessment Reports’ (2017) and ‘Draft Advise Notes for preparing Environmental Impact Statements’ (2015) The assessment involved -: 1 Visiting the site and the surrounding area 2 A review of statutory planning and other documentation in order to ascertain local and wider significance 3 A study of ordnance survey mapping and aerial photography; a review of plans, sections and elevations of the proposed development and Part VIII Planning Scheme documentation Where appropriate and in accordance with the EPA Advise Notes and Guidelines the below table of terms are used to describe the degree, quality and duration of an impact -: Impact Criteria Description Profound An impact which obliterates sensitive characteristics Significant An impact which, by its character, magnitude, duration or intensity alters a sensitive aspect of the environment Moderate An impact that alters the character of the environment in a manner that is consistent with the existing and emerging needs Slight An impact which causes noticeable changes in character of the environment without affecting its sensitivities Imperceptible An impact capable of measurement but without noticeable consequences Terms relating to the duration of impacts as described in the EPA Guidelines are listed as follows: Momentary: lasting seconds to minutes Brief: lasting up to one day Temporary: lasting up to one year Short-term: lasting one to seven years Medium-term: lasting seven to fifteen years Long-term: lasting fifteen to sixty years Permanent: lasting over sixty years Proposed development Old School House, Porterstown Clonsilla, Dublin 15 3 Landscape and visulal impact assessment 1.2 References - Fingal Development Plan 2017—2023 - Environmental Protection Agency, (2017) Draft Guidelines on the information to be contained in Environmental impact Assessment Reports - Environmental Protection Agency, (2015) Draft Advice Notes for preparing Environmental Impact Statements - Landscape Institute (UK) and Institute for Environmental Management & Assessment (2013) Guidelines for Landscape and Visual Impact Assessment, 3rd Edition. 1.3 Nature of Impacts Impacts on the landscape arise in two distinct but closely related aspects. The first impact is on the character of the landscape arising from the insertion of new development or the alteration of elements within an existing context. The second aspect is visual impact, which arises as a result of changes or insertions within a view. The impact on the view depends on the degree and nature of the change and such changes may rise from either ‘visual intrusion’ (i.e. alteration without appreciable blocking) or ‘visual obstruction’ (i.e. alteration with a notable extent or full blocking). It is recognised that as with all landscape and visual considerations, impacts will be influenced and informed, to some degree, by subjective perceptions of how the overall change(s) matter to any given individual. The assessment of landscape and visual impacts includes: - Direct impacts upon specific landscape elements within and adjacent to the site - Effects of the overall pattern of the landscape elements which give rise to the character of the site and its surroundings - Impacts upon any special interests in and around the site - Direct impacts of the scheme upon views and - Overall impact on landscape character and visual amenity 2 Existing Receiving Environment 2.1 Site Context & Description The subject site is a linear parcel of land, located on the southern side of the Clonsilla Road. The 2.32 hectares is a long rectilinear space which is bound to the south by the Royal Canal. Extensive residential and infrastructural development has taken place in the surrounding lands Proposed development Old School House, Porterstown Clonsilla, Dublin 15 4 Landscape and visulal impact assessment over the last number of years. The site is well serviced by public transport in the form of train and bus routes, and is in close walking proximity to a number of schools and public amenities. The landscape character is agricultural lands surrounded by residential developments. The main body of the site can be described as having a unique and distinctive attribute as it is categorised as GS1 Dry Calcareous and Neutral Grassland. These grassland areas are unique to the geographical area and are also found in the Burren, County Clare. The grassland is associated with low intensity agriculture and typically occurs on free-draining mineral soils of various depths refer to ecologist report for further information on GS1 Dry Calcareous and Neutral Grassland. In the eastern portion of the site a protected structure referred to as ‘The Old Schoolhouse’ is located (built in 1854). The building is in disrepair at present, but is an important landmark building to the area. The lands and building are open to views from the north bound Diswellstown Road fly over, and along the Porterstown Road. There are glimpse views of the top of the building from the northern boundary from Clonsilla Village. The southern boundary of the site runs parallel to the National Heritage Royal Canal. The towpath extends from Ashtown (Dublin) to Cloondara (Longford), covering 144km. Between the canal and the southern boundary the tree
