Cardiff council planning officers have recommended that a controversial data centre proposed for the east Cardiff Park and Ride site be approved, concluding that its economic benefits outweigh the negatives.
The recommendation comes after months of opposition from residents, activists, councillors and Members of the Senedd since the proposal was first put forward in January. Concerns have focused on the environmental impact, air quality, noise and the loss of the park and ride facility used by the University Hospital of Wales, Heath.
Developer assurances and council review
Developer Curtis Hall Ltd has previously denied claims that the data centre would have any significant negative impact on the local area. The developer has also confirmed to the council that NHS parking provision at the park and ride will remain until a suitable relocation has been put forward.
Cardiff council has called a special planning committee meeting for November 12 to debate the application, but a holding directive by the Welsh Government prevents approval at this stage. The directive only allows the council to debate or refuse the application while Welsh ministers decide whether they should have the final say.
Planning papers and public response
Ahead of the meeting, council planners published papers recommending that the committee approve the application, subject to the decision by Welsh ministers. According to the papers, officers are satisfied that the development will meet requirements for noise and air quality controls.
The papers detail that more than 3,000 individual representations were made online, by email or in written letters. Only one letter offered support for the development, with the remainder consisting of objections.
Concerns raised by officials and community groups
Concerns were raised by Alex Barros Curtis MP, Anna McMorrin MP, and several MSs including Dafydd Trystan Davies, Zaynub Akbar, Nick Carter, Paul Rock, Cai Parry Jones, Huw Thomas and Shav Taj. Councillors Dan Naughton, Joe Carter, Peter Littlechild, Emma Reid-Jones, Keith Jones, Lee Bridgeman, Joel Williams and James Caruana also raised concerns.
Old St Mellons Community Council and the Cardiff Civic Society also objected to the application.
Regarding the environmental impact, the papers state: “The proposal would result in a substantial change to the ecological character of parts of the site. The principal adverse effects arise from the direct loss and fragmentation of woodland, scrub and grassland habitats, disturbance during construction, effects on protected and notable species, increased lighting, and potential indirect effects upon the River Rhymney and the Severn Estuary European Marine Site.”
The papers add: “The development would also introduce large buildings, roads, security infrastructure and activity into an existing green corridor. These impacts cannot be wholly avoided and therefore require a coordinated package of avoidance, mitigation, compensation, enhancement, long-term management and monitoring.”
Economic benefits and infrastructure gains
Despite these impacts, the papers outline that the “economic and infrastructure benefits” of the development are considered capable of meeting the overriding public-interest test. They state: “The proposal would deliver significant investment in digital infrastructure within Cardiff and south east Wales and would support wider national and regional economic objectives relating to digital technology, artificial intelligence and inward investment.”
The papers also note the development would generate economic activity during construction and operation and contribute to the growth and diversification of Cardiff’s employment offer. It would also bring forward strategic infrastructure, including a new bridge crossing between Pentwyn and Llanrumney, along with active travel improvements, enhanced public transport opportunities, public realm works, flood mitigation measures and upgraded pedestrian and cycling connections. These are described as “substantial public benefits to which significant weight is attached.”
