INTRODUCTION
Council is responsible for managing over 590 kilometres of sealed road throughout the district, including the ongoing maintenance and renewal. Our maintenance crews often find and repair faults, however due to the large size and rural nature of our district, there are sometimes faults that we are not aware of.

If you spot an issue that requires attention, such as potholes, blocked drains, or a broken footpath, please contact Customer Service during office hours. Our maintenance crew will then inspect and, if required, repair the fault. Occasionally, during a peak rain and storm period, there may be some delay due to the large number of requests. Your patience is appreciated during these times.

In some instances, the problems are larger than a simple maintenance repair. These problems will be escalated to our  Engineering Department for further investigation.


SEALED ROADS

We undertake a detailed assessment of our road network every five years that looks at, analyses and condition scores both the seal (surface bitumen) and the pavement (the underlying crushed rock base of the road).

The rating system determines the life remaining in both the seal and pavement by quantifying a number of visible features such as:

  • cracking (lateral, crocodile, transverse)
  • undulations
  • potholes
  • stripping of aggregate from surface
  • deterioration of bitumen binder
  • rutting

We use this rating system to develop treatments for roads and plan in advance which roads will require treatments and when. When a road can no longer be repaired by maintenance, interventions such as seal renewals and pavement renewals are usually used.

SEAL RENEWALS
A seal is the top 30-50mm of bitumen surfacing on the road. When a seal is at or near the end of its life, Council will reseal the road, by placing another seal on top of the old. It is important to ensure a road has a quality bitumen seal on its surface to prevent water penetrating the underlying pavement structure, and to provide a smooth and safe driving surface to road users.

Annually, Council undertakes a resealing program that reseals roughly 25 to 30 roads and restores the seal of the road to 'brand new'.

The Council does two types of reseal - a spray seal resurface, and a hotmix asphalt surface. A spray seal resurface involves a layer of bitumen with fine stone then rolled into the mix. This type of resurfacing is most suited to semi rural and rural roads at higher speeds and with minimal stopping or turning. A hotmix asphalt surface is used predominantly in urban areas to provide a durable surface resistant to stopping, braking, and turning, and a smooth ride at lower speeds.


PAVEMENT RENEWALS
The reconstruction of a road to replace a failed pavement is a much more costly and time consuming process than a seal renewal. Annually, Council annually undertakes 3 to 4 full road reconstructions. This usually happens when the road is 'falling apart' and the road is rutted and has lost its shape and strength. The two different types of reconstructions are granular pavement reconstruction and a deep life full asphalt reconstruction.

A granular pavement reconstruction is used for local and rural roads. The road is excavated out to around 300mm  thick and replaced with new compacted rubble.

A deep life full asphalt reconstruction is used for major roads and is a similar construction to main roads throughout the district. The top 150mm or so is dug out and replaced entirely with bitumen to ensure the road is re-opened in 1 to 2 days. This process is more expensive than granular pavement reconstruction.


ROAD SIGNS
There two types of roads in the district – Council owned roads and the main roads that are owned and managed by the state government Department of Planning, Transport and Infrastructure (DPTI). 

Council only has authority to install or modify signage on Council roads. This excludes speed limit signage which is the responsibility of DPTI.

Main roads that run between and through townships such as Onkaparinga Valley Rd, Strathalbyn Rd, Woodside Road, Torrens Valley Rd, Greenhill Rd are DPTI roads. For requests for new or modification to signage on these roads please contact DPTI.

Council assesses requests in line with the Australian Standards AS 1742 for signage to ensure they meet the criteria. Existing signage in the area is also considered.

For businesses looking to install street signs directing potential customers to their premises, please see our Planning and Building page.

TRAFFIC AND SPEED LIMITS
Speed Limits
There are two types of roads in the district – Council owned roads and the main roads that are owned and managed by the state government Department of Planning, Transport and Infrastructure (DPTI).

DPTI are the only authority with the legislative power to set and change speed limits. DPTI have produced a Speed Limit Guideline for South Australia document that provides a point of reference for applying speed limits throughout South Australia to make roads, roadsides and road-related areas safer for all road users.

Speed Limit Signage
Current legislation in SA does not allow speed limit signage on unsealed roads, and drivers should drive to the conditions.

Installation of new speed limits signs must be approved by DPTI as the speed limit authority.

Speed limit signs are typically displayed on main roads entering townships to signal the transition to a new speed zone.

If you believe a speed limit sign is missing or is warranted please contact us. Please provide in the request:

  • your name, address, and contact details 
  • location of road and required sign
  • why the sign is required and the observations

Speed Limit Reviews
The DPTI document (mentioned above) sets out the process for Council to review and approve requests change speed limits on roads. See Section 2.5.2.2 and 2.5.3 for detailed information.

Council can request a speed limit review by DPTI of a sealed road where it feels an investigation is warranted.

Before requesting a speed limit review by DPTI, Council will assess the road against a number of criteria, including:

  • Traffic counts and function of road
  • Average speeds (based on traffic surveys)
  • Level of development and access points onto the road
  • Roadside hazards and number of crashes in past 5 years

If the road meets the criteria for further review, it will be sent to DPTI to request a review, where a similar but more rigorous process is undertaken.

DPTI Speed Limit Review

If you believe further investigation is warranted please contact us. To streamline the process please provide in the request;

  • your name, address, and contact details 
  • location of road
  • why the review is required and the observations
  • justification that you believe the proposed road meets some of the criteria listed above

​Hoon Driving / Speeding Motorists
Council has no enforcement authority against speeding and hoon drivers. If you are witnessing dangerous driving in your area such as speeding or hoon driving behaviour, please report this to the South Australian Police (SAPOL) by calling 131 444.


STREET LIGHTING
Existing Street Lighting 
The majority of the street lighting in the Council district is owned and maintained by SA Power Networks.

Council pay the annual lighting cost for the running of street lights on Council roads, however replacment and repair of lights is undertaken by SA Power Networks

Any faults should be directed to:
SA Power Networks
Telephone 13 13 66
 
New Requests for Street Lighting
Please contact council to request new street lighting. To streamline the process please provide in the request:

  • your name, address, and contact details 
  • location of requested street light
  • why the light is required
  • evidence that the proposed light meets Council's Street Lighting Policy

Council reviews the street lighting request in line with Council's Street Lighting Policy. If the request is succesful it will then be lodged with SA Power Networks for detailed design and assessment. Please be aware this process may take up to 6 months.


EASEMENTS
Council does NOT have a record of all easements on your property.

Where Council has stormwater infrastructure or CWMS infrastructure running through your property (pits and pipes, NOT creeks) there may be an easement.

To identify if your property has an easement you can obtain a copy of your certificate of title at this link:  Certificate of Title

If the title cites that an easement is 'to Council' it is likely we will have infrastructure there, otherwise another service authority may own the easement(water/electricity/sewer).

You are NOT permitted to build over an easement. Please contact our Planning and Development Department for further information.


ALTERATIONS TO A ROAD RESERVE
Applications for alteration to Council road reserve should be lodged in hard copy at one of Council's service centres.

This form is used for

  • New or alteration of a Driveway Crossover
  • Underground Electrical Connection
  • Underground Water Connection
  • Alteration to Road Reserve Vegetation
  • Decking or Infrastructure (walls/posts) in road reserve 

For the 2019/20 financial year the application fee required to be paid at time of lodgement is $89.00

REFLECTIVE MIRRORS

Council only has authority to install or modify signage on Council roads. This excludes speed limit signage.

Main roads that run between and through townships such as Onkaparinga Valley Rd, Strathalbyn Rd, Woodside Road, Torrens Valley Rd, Greenhill Rd are managed by DPTI.

Requests for Mirrors - DPTI Roads
For requests for mirrors on DPTI roads, please contact DPTI.
DPTI will assess the request for a mirror against their operational instructions operational instructions.

Request for Mirrors - Council Roads
Council applies the same operational and risk considerations as DPTI in assessing applications for reflective mirrors. Mirrors will not be installed on roads with a speed limit greater than 60kmh or within the carriageway, shoulders, or islands. If approved, the applicant is required to fund the cost of the installation of the mirror including all future maintenance and liability issues. Please contact us to discuss your request.


INFRASTRUCTURE REQUESTS
Requests for new infrastructure including footpaths, kerbing, stormwater, sealing of roads are individually assessed and considered in Council's annual budget process against criteria including; legislative requirement for the works, safety risk, Council resolution for the works, projects that align with Council's Strategic Plan.

If you believe the expenditure of funds on NEW infrastructure is warranted please contact us.

Please provide in the request;

  • your name, address, and contact details 
  • location of requested works
  • why the works are required and how they meet the criteria above
