The trade association Interpave has just launched a new case study showing how concrete block permeable paving provides a comprehensive and cost-effective sustainable drainage system (SuDS) for a new housing development without additional land-take.
The case study explores a SuDS scheme at Fleetwood Crescent, the 28-home first phase of a new development in the Eastfield area of Peterborough for award-winning housing association Cross Keys Homes. It makes extensive use of concrete block permeable paving, reflecting Peterborough City Council’s desire to incorporate SuDS in developments. The estate road is a trial site for the adoption of permeable paving by the Local Highway Authority and will be adopted under the ‘Section 38’ process, and its performance monitored.
All the concrete block permeable paving has been designed and constructed in accordance with Interpave technical guidance available from www.paving.org.uk. This scheme demonstrates how concrete block permeable paved drives, parking and adopted roads on a typical new housing development can attenuate, store and treat runoff from all the hard surfaces without additional land-take or other SuDS features. Use of a simple orifice plate flow control protects the local sewer from overloading.
The new Fleetwood Crescent case study and a video of the project, dramatically demonstrating the performance of concrete block permeable paving, are available via www.paving.org.uk.
