Cutteslowe Roundabout, Banbury Rd. Oxford

: I contact you on behalf of a local community group comprised of households in close proximity to Cutteslowe Roundabout. Since its reconfiguration we are concerned that it is now simply a concrete blob with a single tree. We wish to pursue in a practical, low cost and low maintenance way to 're-green' this structure and improve the environment and vista, especially as it is one of the major gateways into the city; particularly so since the opening of Oxford Parkway rail station. Please advise me which authority is responsible for the upkeep of this roundabout.
