Planning precedent report

The provision of alternate entrance and access arrangements from Crag Avenue to serve the permitted data storage centre, energy centre and substation development permitted under Reg. Ref. SD18A/0068, as amended by Reg. Ref. SD19A/0185 including the provision of ducted services connections between the permitted substation on site (permitted under Reg. Ref. SD18A/0068 as amended by Reg. Ref. SD19A/0185) and existing services to the south of the Grand Canal. The proposed ducted services connections will exit the permitted substation compound and run southward, crossing beneath the Grand Canal by way of a horizontal directional drill, before proceeding east and west to connect to existing services located to the south of the Grand Canal. This proposed development is also located on lands within the Grand Canal Corridor to the north of the R134 Regional Road, Clondalkin, Dublin 22.

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.

Alterations to approved plans (Grant of Permission ref PL06S.243151 and PA Reg Ref SD13A/0271 and SD18A/0068) to the previously granted planning permission for the construction of an ESB 110kV Gas Insulated Substation for the use by Crag Digital Limited in support of the development and to incorporate an ESB Network Substation to improve and upgrade power supply to Clondalkin and adjoining areas; the proposed ESB 110kV Gas Insulated Substation is a two storey building of gross floor area of 1,586sq.m and Client Control Room building of an area of 116sq.m; single storey 2MV ESB Substation of 38sq.m floor area is proposed to be constructed to facilitate the construction of the already granted development until completion and commissioning of the proposed ESB 110kV GIS Substation, including for 3 ESB external transformers and 3 Crag Digital Limited external transformers; alterations include for the relocation on site of previously granted client transformers, control building and energy centre ancillary building to facilitate the revised ESB 110kV Substation building layout; ESB Substation and client control building and transformer compound are to be secured with a 2.6m and 3m high palisade fence and access gates; all landscaping and ancillary site works as per previously granted planning permission SD18A/0068.

The proposed development includes retention permission for the reorientation of the gas AGI (above-ground installation) compound permitted under SDCC Reg. Ref.: SD23A/0158 and to retain an existing Gas AGI skid located to the north of the gas AGI compound. The development also includes the retention and completion of an extension to the existing Gas AGI compound to the south, to provide for a pressure regulating and metering station (PRMS) compound area. The PRMS compound extension comprises the following buildings and gas related infrastructure:•Skid House structure with a total area of c. 118 sq.m and overall height of c.3m. •E&I Kiosk with a total area of c. 11 sq.m and overall height of c. 2.7m •Boiler House comprising 2 no. individual units (Boiler House 1 & Boiler House 2) both with an area of c. 22 sq.m and overall height of c.3m. •Gas Quality Building with a total area of c. 3 sq.m and overall height of c. 2.4.m • All associated and ancillary works including valves and pipework, site lighting, boundary treatments, landscaping, drainage and infrastructure. The proposed development is located within a site which is subject to an EPA Industrial Emissions (IE) Directive license.

Alterations to approved plans (Grant of Permission ref PL06S.243151 and PA Reg Ref SD13A/0271) consisting of the following to be constructed in a minimum of two phases: The construction of a similar 2 storey data centre with a gross floor area of c.44,323sq.m associated single storey combined heat and power plant (Energy Centre) with a gross floor area of c.7,109sq.m with ancillary 2 storey operations building with part basement with a gross floor area of c. 2,998sq.m. The Data Centre shall comprise the following uses: offices, canteen, computer and associated support areas, electrical component rooms, plant and associated equipment. The combined heat and power plant shall comprise the following uses: generator and gas fired engine rooms, boiler rooms, chiller rooms, plant and associated equipment. On the site are previously granted gas pressure reduction station and previously granted 110kV substation solely for the use of Crag Digital Limited in support of this development. Also proposed as revisions are removal of 2 end masts for undergrounding of overhead 38kV Power Lines, revisions to Security Hut, omission of Cooling Towers and all revised associated storage tanks, flues, access roads, services, entrance gates and perimeter fencing at 3m high, landscaping and infrastructure inclusive of 94 car parking spaces, retention pond and revised diversion of existing 1200mm diameter arterial sewer as agreed with Irish Water, and all sundry associated minor works. The development will be consequent on previously granted demolition of the existing logistics centre and associated ancillary buildings, retention of existing mobile phone mast and ancillary plant. An Environmental Impact Assessment Reports (EIAR) has been submitted with this application. An-EPA Industrial Emissions Licence has been applied for on 28th November 2017 Reg: P1066-01.

Amendments to the development permitted under Reg. Ref. SD20A/0309 comprising: alterations to permitted ICT Facility buildings 2 and 3, to include internal reconfiguration of the ICT equipment halls, associated electrical and mechanical plant rooms, loading bays, maintenance and storage space, office administration areas, and reconfiguration of screened plant; alterations to the external facades of permitted ICT Facility buildings 2 and 3 to include modification and reconfiguration of fenestration, louvers, loading bays, and access doors, along with an increase in height of 1.2 metres to main parapet level and reduction in the height of rooftop plant to not exceed the parapet height of the buildings, along with the omission of previously permitted flues and exhaust ducts at roof level; omission of emergency generators and associated flues from permitted ICT Facility buildings 2 and 3; The proposed amendments to ICT Facility buildings 2 and 3 result in an increase in their gross floor area (GFA) of 2,511sq.m for each building, resulting in an overall increase in the GFA of the two buildings of 5,022sq.m; Alterations to the water storage tanks serving the permitted ICT Facility buildings, including total increase of 268 sq.m GFA to the permitted pumprooms and a reduction in the scale of the associated water storage tanks. All associated and ancillary works; The application site is subject to an EPA Industrial Emissions Licence relating to the Energy Centre permitted on site (under Reg. Ref.: SD18A/0068 as amended by Reg. Ref.: SD19A/0185).
