Far North District Council has reached agreement with forestry companies to mitigate dust on 50 of their dustiest roads.
The agreement will see dust suppression compounds applied to sections of 50 unsealed roads in the District, providing relief to residents of more than 160 homes worst affected by road dust.
The deal with Hancock Forest Management, Summit Forests New Zealand, and Northland Forest Managers shares the cost with the Council of applying dust suppression compounds on rural roads.
General Manager – Infrastructure and Asset Management Andy Finch says the deal with forestry companies was facilitated by the Northland Transportation Alliance and followed a meeting with community representatives and local iwi affected by dust on unsealed roads.
“Forestry is a very important economic activity for the District, but it impacts heavily on our roads and on residents who live close to key forestry routes. This voluntary contribution from forestry companies acknowledges the industry’s contribution to road dust problems and demonstrates a willingness to offset the cost to ratepayers.”
Dust suppression compounds are a temporary solution for controlling road dust and are sprayed onto the road surface at the beginning of summer. The compounds bond with road dust but do not make the road surface slippery.
While it is significantly cheaper than tar sealing roads, dust suppression compounds have a short lifecycle of around three months, depending on traffic volumes and the impact of wet weather. Treated sections of road are not graded to prolong the life of the product.
Road were selected for treatment based on their ranking in road sealing priority matrix developed by the Council. This uses transparent criteria to fairly and consistently rank all roads across the district for road sealing or dust suppression.
