Cardiff City Council will start the construction of 2 Ponds in the ‘Danescourt Park’ – a green field / park bordered by Llantrisant Road (from the Radyr Filling Station to Heol Isaf), a path from Heol Isaf to Radyr Comprehensive School, and the Danescourt Estate. There are paths from Heol Isaf to Herbert March Close and Buckley Close .

The double ponds are on the right hand side of this diagram near the gardens of Herbert March Close. The temporary vehicle only access situated within the precinct of a Toucan crossing on Llantrisant Road will be made permanent for Council Parks maintenance or emergency access.

The above diagram also shows the ponds around the Llantrisant Road / Heol Isaf junction that are part of the Plasdŵr surface water scheme managed by Redrow under Cardiff Council planning application  21/00645/MJR. This is the only information online about the Council ponds and is not part of any planning application.

Cardiff Council have stated that they are acting under their permitted powers to disperse the highway surface water as Dŵr Cymru Welsh Water sewers will not have the capacity to accept it. The ponds' capacity is stated as coping with a maximum rainfall event that occurs once in 100 years plus 40% 

About half the park has already been fenced off as a construction site, and the access road and ponds excavation will begin soon.

 

There is no information on the Council website other than the Redrow planning application for this scheme for Attenuation Ponds or Basin.

 

This Danescourt Community Association has posed 20 Questions formally to the Council and will be publishing their responses. Clarification has also been requested as to what permitted powers have been used for this scheme and why was there no consultation nor advance notice.
