South Dublin County Council N7 Newlands Cross Upgrade Environmental Impact Statement Arup Consulting Engineers 15.2.9.2 Operational Phase • It is proposed to utilise the existing drainage outfalls post construction where practical. The outfall peak flows will be increased post construction due to increased impermeable road surfaces; therefore flow regulation is required to prevent over capacity of receiving watercourses. This will be provided by means of oversizing drainage pipes and using a flow regulating device (such as HydroBrake or equivalent) where the proposed drainage outfalls. • There will be no use of herbicides, pesticides or artificial fertilisers in any landscaping or subsequent maintenance within 2m of a watercourse. Applications of herbicides or pesticides will be in accordance with manufacturer’s recommendations and confined to periods when the vegetation is not wet from rainfall or dew within a zone of 10m from any watercourse. 15.3 Summary of Residual Impacts 15.3.1 Soils, Geology and Hydrogeology • Residual impacts include the excavation and compaction of soil. Shallow excavation of materials is required through out the area of the junction improvements for road regarding and embankment construction. • The sub-soil beneath embankments will be compacted to achieve the relevant engineering design values prior to embankment construction. This compaction is a permanent impact. • Residual impacts on the hydrogeology include the potential for groundwater contamination during the operational phase. Although as the construction works will generally result in a greater depth of covering over the bedrock aquifer than is currently there, it could be considered that the works will reduce the vulnerability of the bedrock aquifer. • The proposed development will result in an impermeable surface being constructed over the bedrock aquifer. This may have the effect of a minor reduction of groundwater recharge to the aquifer. 15.3.2 Landscape and Visual • The primary significant and negative visual impacts will be during the construction phase and will be short term. • Upon completion of the works the visual impact generally will be moderate and neutral with a localised moderate and negative visual impact to the rear of the houses backing on to the north-eastern portion of the overpass. • The proposed scheme will be seen as a natural improvement to the existing road system, improving traffic flow in the area and reducing the visual clutter, caused by traffic build up, that exists at present at the junction. 15.3.3 Noise and Vibration 15.3.3.1 Construction Phase - Noise • During the construction phase of the project there will be an impact on nearby residential and business properties due to noise emissions from construction activities. The application of the Noise and Vibration Management Plan and the Plan for Control of Noise and Vibration will ensure that noise impact is kept to a minimum consistent with efficient construction practices. 15.3.3.2 Operational Phase – Noise December 2007 Page 245
South Dublin County Council N7 Newlands Cross Upgrade Environmental Impact Statement Arup Consulting Engineers • There are a number of locations highlighted in this document where the proposed Scheme meets all three conditions that must be satisfied before noise mitigation measures are deemed necessary. In these instances, mitigation measures have been specified. Once mitigation measures have been assessed all locations comply with the adopted criterion. • It may be concluded that the proposed road Scheme complies with the appropriate guidance in relation to noise, hence the associated impact is considered acceptable. 15.3.3.3 Vibration • It may be concluded that the proposed road Scheme is not expected to give rise to vibration that is either significantly intrusive or capable of giving rise to structural or even cosmetic damage. 15.3.4 Air Quality • The residual impact on air quality as a result of the proposed scheme will not be significant. 15.3.5 Climate • There will be no residual impact on climate as a result of the proposed scheme. 15.3.6 Ecology • Minor negative impacts associated with the construction phase of the proposed junction upgrade and the use of temporary lands for traffic management during construction will be reduced through the effective implementation of the proposed mitigation and the overall impact of the scheme on ecology will be considered neutral. 15.3.7 Archaeological, Architectural and Cultural Heritage • No residual impacts are envisaged, as all archaeological, architectural and cultural heritage issues will be resolved at the preconstruction and construction stages of the proposed road development. 15.3.8 Material Assets 15.3.8.1 Community • At Newlands Cross Golf Course, with the proposed mitigation measures in place, the Scheme will not have any significant detrimental effects on the playing of the course or it’s amenity. 15.3.8.2 Property & Material Assets • Residual impacts cannot be assessed at this stage, as mitigation measures in the form of compensation are not part of the EIS. 15.3.9 Surface Water and Drainage • There will be no significant residual impact on either the Ballymount Park / Camac combined surface water system or the Poddle and Dodder River systems arising from the upgrading of the Newlands Cross Junction.
