Appendix 3.3 - Appraisal of the construction phase impacts associated with the development of the EV charging infrastructure under the Strategy
Construction Detail
Appraisal of Construction Phase Environmental Effects
Normal Speed Stations
Fast Speed Stations
Indicative Duration of Works
5 – 10 days some additional time may needed for commissioning Typical day time hours with potentially road crossings carried out in the evening (1 evening) Installation of electric ducting and cabling and mini-pillar; modification of existing kerbs and/ or construction of a concrete plinth, the erection of a single EV charging bollard, road markings and signage.
4-6 weeks some additional time may needed for commissioning Typical day time hours with potentially any road crossings carried out in the evening (2-3 evenings) The construction of a new mini-pillar or substation, installation of electric ducting and cabling; the re - construction of 2-4 parking bays including kerbing and potentially some modifications to the existing gullies, the erection of 1-2 EV charging station, landscaping, road markings and signage. Mini-digger, roller, construction van/ pick up truck, concrete mixer, mini dumper Existing drainage network to be maintained only gullies to be replaced/ relocated, any surface runoff during groundworks will not have a direct connection to the existing drainage network and any retained water will naturally permeate through the sub-bases.
Environmental effects associated with the construction of EV charging stations will be temporary in nature. Construction works are envisaged to be relatively minor in nature given the magnitude and spatial extent of anticipated works. It is not envisaged construction activities will generate surface water run-off or significant discharges to ground, assuming standard good construction practice will be adopted during the works. Excavation works associated with the construction activities will be relatively limited given the scale of the works. It is not expected the construction of the charging stations will have any significant effect on the soils environment as such, although potential still exists for the limited excavation activities to unearth unknown archaeological remains - particularly in the context of Cork City's historic core, and/or where excavation for cabling is being undertaken. Construction activities occurring in the context of the built urban environment of Cork City Council may however lead to temporary traffic impacts or localised noise and dust impacts on people, residences and businesses, particularly where more sizeable 'fast' charging stations are being constructed, or where development projects overlap, intersect and/or are within close proximity to one another. It is not expected construction of charging infrastructure will lead to any significant resource or waste management requirements, or any significant visual effects given the scale and temporary duration of anticipated development. It is expected that the construction of charging stations in urban areas in the city will generate minimal biodiversity or invasive species impacts, however, where charging stations are situated at or near to biodiversity sensitive areas, construction activities may generate localised adverse impacts on important habitats, flora and fauna - through a reduction in habitat area or disturbance to key species, for example.
