GOWERTON: Developer wants traffic concerns omitted from environmental study on 216 homes rejected by councillors

Persimmon has asked the Welsh Government to leave traffic out of the environmental study on its 216-home scheme beside Gowerton railway station.

Swansea councillors refused the scheme on traffic grounds by a single vote.

The request would strip out ten topics in total. Traffic, flooding, noise, air quality, wildlife, landscape, heritage, ground conditions, climate and the effect on local services would all go, leaving only the nutrients 216 households would flush into the Burry Inlet catchment.

Officials circulated it on 6 August to nine public bodies, including Swansea Council, Natural Resources Wales, Dŵr Cymru, Network Rail, Transport for Wales and the Welsh Government’s own transport directorate. They have until Thursday 17 September to reply.

The next day, a lorry got wedged under the railway bridge at the entrance to Fairwood Terrace, its roof peeled open against the girders. Trains between Swansea and Carmarthen stopped for the best part of two hours.

Traffic backed up through the village and the roads around it, as it does every time. Local councillors say even a minor strike puts Gowerton into lockdown.

The council put the houses there in the first place

The land was earmarked for housing by Swansea Council itself, inside a strategic site written into its local development plan and consulted on publicly, covering roughly 1,320 homes across three parcels north of Waunarlwydd and Fforestfach.

Residents put their objections on the record at the time. They warned that cleaning up the old Gorwydd Colliery workings would be so expensive the site might not be commercially viable, and that the sewers could not take the flows, which would end up in the protected Burry Inlet.

Plans for 230 homes went to consultation in December 2022 and drew nearly 900 objection letters and a 300-signature petition. In September 2024 the council’s planning committee refused them against its own officers’ advice, and Persimmon and site promoter Urban Style Land appealed to Welsh ministers that December.

Sewage, not traffic, is what stopped the clock

In April, a planning officer ruled the appeal could not be decided at all until Persimmon produced a full environmental statement. The trigger was the second of those decade-old warnings: the site drains into the Carmarthen Bay and Estuaries protected area, already failing its conservation targets because of nutrient pollution, and updated evidence from Natural Resources Wales meant the effect of the new foul waste could not be ruled out.

That ruling also accepted the campaigners’ argument that the site cannot be judged in isolation from everything else planned along the A484, where close to 3,000 homes are being built or proposed between Penllergaer and Gowerton. Persimmon then went quiet for more than five weeks on what the study should cover. The answer arrived in July.

Ten topics out, one in

The reasoning offered for each dropped topic is close to identical. The council assessed it during the planning application, consultees did not maintain objections, and nothing material has changed since.

On traffic, the scheme’s own answer to congestion is a new signal-controlled junction where Fairwood Terrace meets Victoria Road, directly beneath the Trafle Mill bridge. Network Rail named that bridge the most struck in the whole Wales and Borders region, hit 33 times in a decade.

Campaigners want something bigger than a set of lights. The council’s allocation for the strategic site requires a new spine street running through it, and Save Gowerton from Gridlock argues that road, linking eastward towards Titanium Road, is the only thing that would keep the new traffic off Victoria Road and the bridge. The group says none of the applications submitted across the site delivers it.

On flooding, Natural Resources Wales told officials the scheme does not fully comply with the current version of TAN15, the Welsh Government’s flooding policy, and that highly vulnerable development is not supported in flood zone 3. It went on to say the flood assessment and mitigation were still enough to rule flood risk out as a likely significant effect, and that second finding is the one Persimmon relies on to drop flooding entirely.

The land also sits wholly inside the Alcoa Wet Meadows wildlife site, where surveys found several bat species foraging and building would clear woodland, purple moor grass and rush pasture. Ground conditions are on the list too, on land whose uncapped mine shafts and colliery waste underpin the developer’s claim of £10m in abnormal costs, the same claim used to justify offering Gowerton 10.2% affordable housing, no school money and £175,000 in total community contributions.

The test the developer’s list may not survive

Officials have set a wider yardstick than the one Persimmon is working to. The study, they told consultees, should cover any environmental aspect likely to see significant effects “if the mitigation described in the application documents is not secured”. Almost every dropped topic was signed off on the basis that planning conditions would deal with it.

What officials cannot do is force the point. The regulations do not let them issue a binding scoping direction on an appeal, so they will publish a non-binding scoping outcome instead.

Campaigners raise the council’s new Persimmon deal

Carl Jones, who leads Save Gowerton from Gridlock, says his group has been added to the consultation and is preparing evidence for a full study. It lodged a submission on 10 August pointing to Swansea Council’s agreement to buy 141 affordable homes from Persimmon at Garden Village, announced days earlier, arguing the council’s earlier planning clearances should not now be treated as an objective starting point. The council has previously called conflict of interest allegations unfounded, saying its planning decisions rest on planning grounds alone.

Whatever officials decide, the study still has to be written, and the appeal cannot be determined either way until it is. Swansea Council lists the consultation as 2026/1328/SCO.
