Heat Mitigation Trial - Zones 1 to 5

News

About

The Northern Territory Government is trialling a series of initiatives that will help reduce the impact of heat in our tropical city and rejuvenate Darwin’s CBD.

A heat mapping study undertaken in the Darwin CBD demonstrated high level surface temperatures exceeding 60 degrees in a few locations, including Cavenagh Street.

Over an 18 month period, five zones of heat mitigation methods will be trialled along Cavenagh Street, between Bennett and Knuckey Streets.

Five zones of heat mitigation methods

Zone 1

Intersection upgrade

  • New turning lane
  • New landscaping
  • New pedestrian shade structures at each corner
  • New vine growth to the boundary fence of corner vacant block
  • Works completed in Zone 1 are being managed and delivered by the City of Darwin and complement the heat mitigation trial.

Zone 2

Construction of a shade structure

  • Construction of new light-weight framed structure to enable vegetation growth for shade
  • Removal of the existing central median strips
  • Misting to the underside of the structure will help improve thermal comfort
  • New up lighting at central vine locations
  • Power and water connections in median strip to allow for future events, such as markets
  • Vine planter and irrigation in central median
  • Clearance for vehicles and re alignment of parking; and
  • Landscaping

Zone 3

Cool Surface Treatments/Small Shade Structures

  • Two new pedestrian / shared zone crossings to align with the existing arcades
  • New cool, reflective pavement coating to road surface between the crossings; and
  • Standalone shade structures on both sides of pedestrian crossings. Note: car parking numbers are not affected due to new angle of parking

Zone 4

Relocatable Planters

  • A combination of established trees in large relocatable planters, and smaller vegetation planters to provide up to 20 per cent canopy cover
  • Informal pedestrian nodes such as seating and shaded waiting areas; and
  • New landscaped traffic islands to provide shade to car parking and passively slow vehicle movements. Note: car parking numbers are not affected due to new angle of parking.

Zone 5

Intersection Upgrade at corner of Knuckey and Cavenagh Streets

  • Two new established shade trees on intersection corners where there are currently none; and
  • A new cool, reflective crossing surface.
  • As part of this project, government have investigated options to increase parking capacity along Cavenagh Street. By increasing the current parking angle 10 degrees, there will be an additional 3 parking spaces, providing 117 parking spaces between Bennett and Knuckey Streets.
