Persimmon Homes Coed Dyffryn Aberaman

Yesterday I called in on Persimmon Homes Coed Dyffryn Aberaman to enquire about the reinstatement of public footpath destroyed during the heavy rain and rising water in the River Cynon.

The representative at the site office said the residents are in talks with Rhondda Cynon Taf Council about the reinstatement of the footpath.
The representative said, “There were concerns about the people using the path” I presume walking through the site to the many industrial retail outlets that adjoin Coed Dyffryn Aberaman.

I questioned the Persimmon representative that the problem has only raised since the Flooding River Cynon back in January when a large volume of material was placed on the footpath, as the floodwater was getting higher.


The mound has been removed for some months now, the once tarmac section of footpath is now just rough hardcore difficult to walk or push a wheelchair.

All Aberaman and Cwmbach residents want to know when will the tarmac be reinstated.

E-mailing Persimmon Homes no response received, it shows the company policy is to ignore local residents concerns.

Why presume (as stated above)?? Maybe it's just me... Everyone knows about the flooding issue, you can't sure be happy to wade through feet deep water. No one's going to want to see the estate flooded nor make their way to cwmbach after the rain when even the rail track fills with water so... don't be so daft as to argue the point. Let's just get the 'bund' properly finished off. If you live in a valley and you get three days of heavy rain (as per any recent history will show) it gets 'wet' at the bottom lol.

A Statement from from Natural Resources Wales

Please see below information and statement about the Persimmon development at Aberaman.

With regards to your questions about the footpath, I think these might be better directed at the council, as they have liaised with the developers over the design of this.


Gary Purnell, flood risk technical specialist, from Natural Resources Wales (NRW) said:

“We were consulted as part of the original planning application to make sure the proposed development would not be at risk of flooding or increase flooding elsewhere to nearby communities.

“Since planning permission was granted, the developer proposed to change the layout of the development and we were re-consulted by the Local Planning Authority. This would have required an updated Flood Consequence Assessment by the developer for the proposed changes.

“However, we have since been informed that the developer has reverted back to their original plans and the development will now proceed to construct the remainder of the homes in accordance with the original approved planning consent and in accordance with the original conditions for managing flood risk.”


The original planning permission was granted by Rhondda Cynon Taff County Borough Council in 2005.

Following consultation and advice from Natural Resources Wales's predecessor, Environment Agency Wales, the following flood risk related conditions were applied by the Local Planning Authority.

The proposed flood mitigation works and all associated structures and channels must be constructed prior to any built development, including the raising of ground levels associated with the construction of the housing development, commencing on site;
Finished floor levels must be constructed a minimum of 600mm above the theoretical 1 in 100 year flood level and all infrastructure, roads, and car parking areas are to be constructed a minimum of 300mm above the theoretical 1 in 100 year flood level;
The theoretical 1 in 100 year flood level for the River Cynon at this location is currently estimated at 116.19m above Ordnance Datum (mAOD). However, it should be noted that although this information is considered the best available at the current time, levels may be subject to change in the future.


Persimmon Homes have tested a permanent solution to retain the footpath at a higher level into the development. This solution and design has been worked through with Rhondda Cynon Taff County Borough Council highways department.

NRW’s only involvement in this has been in the testing of this in the flood model.
