PERMEABLE PAVING

HELPS MEET NEW PLANNING REQUIREMENTS FOR TREES

Extensive urban tree planting and retention of existing trees , with provision for long-term maintenance , has just become a priority with new government policies taking effect . Concrete block permeable paving offers an important opportunity to help satisfy these requirements with irrigation , integrated with SuDS , hard surfaces and urban design – as the trade association Interpave explains .
By August 2021 , birch trees and other green infrastructure are healthy and well-established .
The latest requirements for street trees have been established in the July 2021 ‘ National Planning Policy Framework ’ ( NPPF ) for England . The NPPF sets out what local planning authorities ( LPAs ) will require for all developments , when setting local policies and also considering planning applications for all developments . The NPPF states that :
‘ Planning policies and decisions should ensure that new streets are tree-lined and that opportunities are taken to incorporate trees elsewhere in developments ’. This is backed up by other recent government and local guidance such as the ‘ National Model Design Code ’ which says : ‘ All schemes will be expected to follow national policy by achieving a 10 % net gain in biodiversity . All new streets should include street trees ’.
