National Parks Board (NParks) maps Heritage Road Green Buffer zones established under Singapore’s 2005 Heritage Roads scheme to protect iconic tree-lined corridors. The GEOJSON layer shows where Commissioner of Parks & Recreation approval is required before cutting vegetation or placing structures within buffers. Urban heritage and greenery researchers can overlay buffers with street-tree and conservation datasets. This collection translates NParks’ “green tunnel” policy into geospatial controls for designated heritage roads.
The Heritage Roads scheme was implemented by the Government in 2005 to recognise and protect roads with lush roadside trees and multi-layered vegetation that create "green walls" and "green tunnels" effects along certain roads. The data show the extent of the Heritage Road Green Buffer whereby written approval must be obtained from the Commissioner of Parks & Recreation for the cutting or removal of any tree or plant within the designated Heritage Road Green Buffer. This includes any altering, closing up or removal of any Heritage Road Green Buffer; erecting or placing of any structure or object (whether temporary or permanent) in, above, across or under any Heritage Road Green Buffer; and erecting, constructing or laying within any Heritage Road Green Buffer any fence, retaining wall, foundation, manhole, pipe, cable, mains or any obstruction or structure (whether temporary or permanent).
National Parks Board GeoJSON of Heritage Road Green Buffer extents protected since the 2005 Heritage Roads scheme for lush roadside “green walls” and “green tunnels.” Tree works or structures within these buffers require written approval from the Commissioner of Parks & Recreation; planners and developers check buffer extents before roadside works.
