Road maintenance

Find out which roads are scheduled for resealing and / or renewal.

Roadworks and Closures

Most of the sealed roads in the Whangārei district have a chip seal surface which is stone chips embedded in a layer of bitumen.

Resealing 

The seal on a road is like paint on your house - it keeps water out of the structure underneath. Like paint, the seal breaks down over time and starts to let water in.

When the surface of a street starts to break down it is time to reseal. The ideal time to reseal is just before any damage occurs, so your road may still look to be in good condition. We aim to keep it that way.

Resealing involves the following:  

  • minor repairs are carried out prior to resealing
  • the resealing contractor will contact residents in the street about a week before work begins
  • hot bitumen is sprayed and stone sealing chips are spread and rolled in
  • excess sealing chips are swept away and road marking is reinstated within 48 hours
  • as many as three additional sweeps may follow in the next six months. 

Renewal

Road renewal covers the reconstruction and strengthening of the road surface and layers and can include realignment and widening.

Road renewal is undertaken when road surfaces become potholed, cracked, develop corrugations and rutting or the road subsides.

All roads reach a point where it is more economic to renew them than to continue to repair. 

A programme of resealing and renewal work is usually determined at the beginning of each financial year and contracts are awarded through a public tendering system.

Drainage improvements are usually undertaken as part of road renewal works.

Routine maintenance of unsealed roads generally includes strengthening and smoothing when the road surface fails. Failure includes potholes, rutting and corrugation.

Drainage improvements are usually carried out in conjunction with both strengthening and smoothing.

Ratepayer subsidised seal extension

Council supports a ratepayer subsidised seal extension programme each year for low volume rural residential roads.

The following criteria are used as the basis for the acceptance of applications:

  • applications to be made to Council in the form of a petition representing support from the residents of the road. 
  • applications in any one year to be prioritised taking into account as one of the criteria the degree to which the project will support our overall seal extension strategy and programme
  • the prioritised list of applications to be submitted to the Infrastructure and Services Committee for approval
  • all applications to be supported by at least 80% of the landowners in the area of benefit
  • A ratepayer contribution of $4000 plus GST will be required from each property owner towards the cost of road sealing from the properties on the section of road to be sealed. 

 

Routine inspections are completed on roading structures throughout the district and a schedule of replacement and renewals is developed.

Structures include:

  • bridges
  • large drainage structures e.g. culverts
  • foot bridges
  • fords
  • bus shelters
  • retaining walls
  • guardrails and railings
  • pedestrian under/over passes
  • cattle underpasses.

Council does not own any cattle underpasses, although they are inspected as part of the structures inspection programme and maintenance issues are passed onto the owner to attend to.

Footpaths and shared paths are inspected and maintained as part of the pavement, surface and drainage contracts for each area and include kerb and channel repair as required.

Footpaths and shared paths that link key community areas and access to community services, such as hospitals and schools are considered priority routes.

High volume areas such as the central business area of Whangārei are also considered a priority, particularly to ensure that  physically disabled people are not disadvantaged in accessing services in the city.
