SD24A/0201W

The development proposed will supersede the permitted ICT Facility 4 under Reg. Ref.: SD20A/0309, as previously amended under Reg. Ref.: SD22A/0093 and Reg. Ref.: SD23A/0158. A five-year planning permission is sought in respect of this proposed development. The proposed development comprises the following: • Construction of an ICT Facility Building (ICT Facility 4), with a Gross Floor Area (GFA) of 15,744 sq.m and a parapet height of c. 21.80m (with flues located at roof level, c. 4.5m over parapet height), over 3 no. levels, located in the southern portion of the wider landholding. This ICT Facility includes an associated external plant area of c. 1,796 sq.m over two levels, accommodating 22 no. emergency generators and associated flues. • The ICT Facility building will accommodate ICT equipment halls, associated electrical and mechanical plant rooms, loading bays, maintenance and storage space, office administration areas and screened plant. • Construction of ancillary structures including a guard hut, fire hydrant water storage tanks, fire hydrant pump plantroom, water mist fire protection pump plantroom and water tanks, and cold water plantroom to the west of the proposed ICT Facility 4. • Construction of a revised internal road network and circulation areas to serve ICT Facility 4, footpaths, provision of 25 no. car parking spaces (including 2 no. disabled parking bays) and 18 no. cycle parking spaces within a bike shelter. • Lighting, boundary treatments and all ancillary and associated development (including the construction of an underground foul and storm water drainage network, and utility cables). • Hard and soft landscaping and planting, lighting, screening, and all associated works, including underground foul and storm water drainage network, boundary treatments and security fencing, attenuation areas, and utility cables. An EPA-Industrial Emissions Directive (IE) licence will be required to facilitate the operation of the proposed development.

Refused

Core Refusal Reason

Failure to demonstrate sustainable energy usage and grid capacity compliance, alongside significant information deficits regarding environmental, design, and infrastructural impacts.

Decision Maker's Conclusion

  • The applicant failed to demonstrate adequate grid capacity or sufficient on-site renewable energy provision to justify the development on EE zoned lands.
  • There is a significant lack of technical documentation, including a design statement, traffic details, and adequate SuDS and flood risk assessments.
  • The proposal fails to ensure the protection of biodiversity and ecological values associated with the adjacent Grand Canal and proposed Natural Heritage Areas (pNHAs).

Decision Document Summary

This application sought to supersede a previously permitted ICT facility at 3-4 Crag Avenue, Clondalkin Industrial Estate. The proposal was refused primarily due to concerns over electricity grid capacity and the lack of 100% on-site renewable energy, which is required for data center developments under the South Dublin County Development Plan 2022-2028. Furthermore, the application was deemed deficient in critical areas including design mitigation for visually sensitive locations, ecological pr...
