Residents around Gwaelod-y-Garth are being told to avoid two closed routes and stay out of local rivers after flooding affected 15 properties and forced the evacuation of 13.

Cardiff Council said Main Road in Gwaelod-y-Garth and Heol Goch between the village and Pentyrch remain closed while emergency work, investigations and clean-up operations continue. Motorists should follow the signed diversions because damaged roads, debris and concerns about nearby embankments are still limiting safe access.

The public should also avoid entering the affected watercourses and keep dogs out of the rivers while possible pollution is investigated.

Fifteen properties affected and 13 evacuated

South Wales Fire and Rescue Service evacuated 13 properties during the incident on the previous day. In total, flooding affected 15 properties across the area.

Cardiff Council housing officers have been helping displaced residents. Accommodation was arranged for one family overnight, while another family was due to receive support on the morning of 31 July. Other affected families made private arrangements.

Council officers from Highways, Flood Risk Management, Transport, Waste Management and Housing attended throughout the afternoon and evening to support the emergency response and residents. The official update did not identify the cause of the flooding, and investigations remain under way.

Main Road and Heol Goch remain closed

Heol Goch is closed in Pentyrch beyond its junction with Clos Goch for traffic travelling out of the village. The restriction covers the route towards Gwaelod-y-Garth.

Main Road is closed beyond the South Glade junction for vehicles approaching Gwaelod-y-Garth from the A470 and Ty Nant Road roundabout. The section between the roundabout and South Glade remains open for residents, businesses and visitors who need to reach the 24-hour veterinary practice on Gwaelod-y-Garth Industrial Estate.

Access also remains available to South Glade, River Glade and nearby side streets. Main Road is fully closed beyond South Glade, and drivers have been asked not to pass closure signs or attempt to use the restricted section.

River access warning during pollution checks

Residents have been advised not to enter local river watercourses because of the possibility of pollution following the flooding. Dogs should not be allowed to swim in the water until the investigations have been completed.

The warning remains precautionary while agencies assess conditions. Cardiff Council has not given a date for lifting it.

Housing support for displaced residents

Anyone affected by the flooding who has housing concerns can contact the Cardiff Council Housing Options Centre on 029 2057 0750.

The service is available to residents who need help following evacuation or damage to their property. The council said its housing officers would continue working with affected households as the response progresses.

Clean-up and safety investigations continue

Highways and Cleansing teams are removing mud, silt, debris and other obstructions where conditions allow. Significant highway damage and continuing concerns about the roads and surrounding embankments mean the closed sections cannot yet reopen safely.

Cardiff Council is continuing to work with emergency services and partner agencies. Council leader Chris Weaver said resident safety and wellbeing remained the priority, with teams assessing damage, supporting households and carrying out clean-up, investigation and repair work as quickly and safely as possible.
