Report of the Head of Highways and Traffic Management

Please note that the following recommendations are subject to consideration and determination by the Cabinet (and confirmation under the provisions of the Council’s Constitution) before taking effect.

Recommendations: It is recommended that: (a) progress on 2012/13 schemes detailed in Appendices I and II to this report be noted; (b) the strategy for delivery of the 2013/14 HSM/BAS programmes as described in this report and set out in Appendices III and IV be approved; (c) detailed allocation of the available budget to schemes be determined by the Head of Highways and Traffic Management on the basis of priorities identified from technical surveys and inspections, and within the limits of the approved budget; (d) authority to amend the programme to maximise the impact of the programme be delegated to the Head of Highways and Traffic Management, within the agreed policy guidelines subject to the approval of the Cabinet Member for Highways and Transportation for any budget changes to individual schemes exceeding £25,000.

1. Summary

This report covers the Capital Programme for Highway Structural Maintenance (HSM) and Bridge Assessment and Strengthening (BAS), giving a progress report for 2012/13 and outlining the programme for 2013/14.

This is the third year of a four year grant for Local Transport Plan maintenance block which provides known funding allowing medium term planning, albeit at a level insufficient to arrest annual asset depreciation.

The Chancellors Autumn Statement provided welcome additional funding to Local Authorities for the repair of the road network.

2. Background

A well maintained highway network is an essential requirement for the successful delivery of County Council’s Strategic Plan 2011-2015; in particular the pledge to maintain 96% of A and B roads in good condition. The ability to efficiently transport people and goods around the County underpins Devon’s economy and has a direct impact on the quality of our environment.

Targeting and carrying out this maintenance effectively and efficiently, whilst integrating policies for freight, public transport, walking and cycling, will enable the County Council to demonstrate that it applies the principles of good asset management to all its highway and transport assets that are needed to meet the objectives of the Devon Local Transport Plan (DLTP).

The results of the 2012 National Highways and Transport (NHT) Public Satisfaction Survey reflect public perception of performance, importance and desire for various activities to be funded. Analysis shows that the condition of the highway network and the speed and quality of repairs are important to the public (see Table 1).

What the public voted for

Three of the last four winters (2008/09 – 2010/11) have been more severe in terms of adverse weather events than any in the last 30 years. This year has seen extreme rain fall events with 2012 experiencing the second highest on record. This has been interspersed with cold spells. The effects are felt not just in the cost of dealing with the events as they arise in their immediate aftermath but also in serious ongoing attrition of the surface and structure of the County’s highways.

3. Asset Management

As the local highway authority, Devon has the duty to maintain a road network of 12,850 kilometres comprising:

 970km principal (A) roads  660km non-principal (B) roads  4510km non-principal (C) roads  6710km unclassified roads.

There are basically three types of maintenance works undertaken:

(a) Reactive repairs such as pot-hole filling, dealing with flooding, overhanging vegetation and the like, which, if neglected, would pose a potential danger to roads users. (b) Routine maintenance such as gulley emptying, grass mowing, cleaning and clearing of drainage pipes, ducts and channels and the like, mostly carried out to a defined frequency, (c) Planned, programmed or structural maintenance such as resurfacing, reconstruction, surface treatments, which is aimed at keeping roads structurally sound and reducing long term maintenance costs. This work is largely funded from this budget.

It is the third type of work that is necessary to preserve the value of the Council’s highway assets and it is this type of work that is covered by this report. Neglect of revenue funded reactive and routine maintenance, however, will reduce the service life of the assets and therefore tend to reduce asset value in time, which is why these aspects of the service must not be overlooked in revenue budget setting exercises. Revenue funding is covered in a separate report to this Committee (HTM/13/24).

In 2010 the Department for Transport (Dft) made an additional £3.6 million grant for roads where winter damage was evident. A further £9.3 million was made available in 2011 for this purpose. Although this grant was not available in 2012/13, the additional £5 million in the revenue budget was a welcome addition to the programme. In December Dft announced an additional £6.0 million maintenance allocation for 2013/14, followed by £3.2 million in 2014/15 to support local highway maintenance.

4. Trends in Condition

Machine based (“SCANNER”) condition surveys indicate that minor C class and unclassified roads, (which together comprise 87% of Devon’s road length), are still deteriorating. The figures 1 to 3 attached show the trend over the last few years for the proportions of each part of the network that are green, (showing only minor deterioration), red (that should be considered for maintenance works immediately) and amber (indicating stages of deterioration in between). There is not as much data for unclassified roads but preliminary analysis shows a similar picture for these roads as for C roads. Main (A and B) roads have been kept in a relatively good condition (although some are visually getting worse following recent storm events), in accordance with the pledge in the Council’s Strategic Plan, but this has been at the cost of the more minor roads in the network. Figures 1 and 2 show the trend for this part of the network. The C and unclassified roads have far less percentage green and far more percentage red than A and B roads. They are of weaker construction and therefore will be far more susceptible to potholes over the coming months and years.

A key issue for road users has been the abnormally large number of potholes that have appeared throughout the network, largely caused by water penetration and freeze/thaw cycles. The Council repaired nearly 180,000 potholes in 2010, (an unprecedented number) 120,000 in 2011 and nearly 115,000 in 2012. Therefore the upward trend appeared to have been reversed by doing permanent repairs to the most susceptible roads using the DfT’s winter damage money, the HSM budget and the Council’s own resources. However, following the 2012 storms and flooding large numbers of potholes are again appearing so a significant challenge remains.

It is clear that the general condition of a large part of the highway network is such that it is vulnerable to the formation of potholes and will remain so unless sufficient money is invested to repair the damage permanently and then keep pace with normal wear and tear and deterioration. This raises the risk of a consequential increase in insurance claims.

The National Highways and Transport public satisfaction survey results have shown that Devon compares well with other authorities and is held in comparatively high regard by our road users in key areas, but this position cannot be sustained unless budgets are sufficient to hold deterioration of the network in check. The condition of road surfaces is an area of low public satisfaction and obviously the number of potholes will have had a bearing on this.

2012/13 has seen a marked increase in the number of severe flooding events compounded by prolonged periods of rain. High river levels and saturated ground conditions test the robustness of Devon’s bridges, retaining walls and structural embankments. Two Listed bridges were lost this year and another so severely damaged it requires replacing. Although we have to accept the changes in conditions, it is necessary to continue to spend limited budgets effectively by applying sound asset management techniques to understand the condition of bridges and structures and to plan to undertake preventative maintenance to protect them.

5. Strategy and Analysis

Devon’s highway and bridge network represents the largest capital asset managed by the Council. The asset has been valued at £10.2 billion (Gross Replacement Cost) under newly published CIPFA guidance. This includes all highway assets such as footways, bridges and street lighting. Carriageways (road surfaces and the underlying construction layers) form by far the greatest part of Devon’s highway assets by value. The value of carriageways alone is £8.5 billion, with a current total depreciation on this figure of £687 million, which is in line with previous calculations for the value of the backlog in road maintenance work. A certain level of backlog is to be expected and can be managed, but it is important that it is not allowed to increase each year. Unfortunately the Depreciated Replacement Cost has increased by over £50 million for each of the last 2 years and to stop this happening and keep the roads in their current overall condition would cost an average of approximately £64 million each year, as calculated using models developed by our advisers, WDM Ltd. The current budget does not provide for this, and deterioration on some classes of road is inevitable.

Devon’s Strategic Plan includes the pledge to keep 96% of A and B roads in good condition. This will be addressed by implementing a suitable programme of structural maintenance works, including surface dressing to prevent further deterioration of ‘amber’ sites (see section 4).

The money left after funding the pledge for A & B roads will be insufficient to prevent a significant deterioration in C class and unclassified roads.

The Non Principal Road Recovery Strategy has been used to target important routes to settlements with a population of over 500 and linking communities, roads serving industrial estates, urban local distributor routes, and pre-salting routes not covered by the above. This strategy is helping to deliver a Strategic Plan objective of “connecting with Devon Communities”, and will complete the link with winter service objectives, and the strategic target for B roads.

This strategy has so far tended to concentrate efforts on the non-principal classified network, and very limited funds have been available for structural maintenance on the rest of the minor road network. The reactive defect repair regime and adherence to the cyclical maintenance regime keeps the unclassified network usable, safe, and generally fit for purpose, although this will be difficult to sustain with more revenue reductions. Where these routes are suitable for surface dressing this type of repair will be undertaken in association with the required preparatory patching.

The strategy above will continue to be developed and will be subject to some local flexibility and “common sense” variation to treated lengths.

The programme to upgrade bridges on the principal roads to meet the 44 tonne gross vehicle weight capacity has been substantially completed. Strengthening works to bridges on lesser categories of highway is being prioritised to be consistent with the maintenance principles adopted for the whole highway network. Proposals are in place to strengthen up to nine sub standard bridges during 2013/14. These have either a very low carrying capacity or show significant signs of distress. Where appropriate, other substandard bridges are being managed using a risk-based approach developed by the Highways Agency and adopted by the County Council.

The effects of extreme weather events continue to impact on all highway structures with flooding events, threatening bridges which are vulnerable to scour. An exceptional inspection of bridges is being undertaken in 2012/13 to be completed by the end of March to identify any structures that have been affected by scour as a result of the high river levels. This may require adjustments to planned programmes. Three significant scour protection schemes were completed during 2012/13. Forward design on five schemes will progress to the construction phase during 2013/14.

The weather events experienced since July 2012 have caused significant damage to retaining walls and initiated land slips on many embankments and cutting slopes. The latent effects of periods of heavy rain and saturated ground conditions compound this problem so a significant proportion of the highway structures budget has been assigned to strengthen or reinstate these.

Work continues on the assessment of older structures, and this year will focus on the stock of modern post tensioned bridges which require detailed inspections and assessments on an 18 year cycle. These structural assessments are necessary to help identify and prioritise essential works and to best maintain and improve the condition of the bridge stock.

The programme arising from the risk ranking of all bridge parapets continues, with mitigation works on high priority sites due for completion this year and further sites programmed for next year. The programme to address high risk road over rail bridges and road/rail proximity sites will have been substantially completed during 2012/13. Remaining sites, which have been jointly assessed with Network Rail as low risk, do not offer value for money or significant further risk reduction by undertaking additional protection works.

The renewal and major maintenance programme to carry out bearing replacement schemes will continue but efforts will also be focussed on the inspection and assessment of essential bridge components, particularly bearings and joints to develop a prioritised replacement programme.

6. HSM and BAS Programmes for 2012/13

The HSM and BAS LTP settlement for 2012/13 was £35.123 million.

Appendix I shows progress with the HSM programme for 2012/13.

Appendix II shows progress with the BAS programme for 2012/13.

7. HSM and BAS Programmes for 2013/14

Devon’s allocation for 2013/14 is £39.442 million, including the additional allocation of £6 million, referred to in Section 3 above.

It is proposed to allocate the available funding to HSM and BAS as outlined in Appendix III and Appendix IV.

Key elements include:

(i) HSM Principal Roads:

£2.8 million to specific larger schemes with a high Value for Money Index and schemes which will rectify carriageways with potential skidding defects.

£5.3 million on surface dressing and preparatory patching works. This will surface dress carriageways in 2013/14 and prepare for the 2014 dressing programme.

Both will target “red” and “amber” SCANNER data and help to further contribute to the County Council’s Strategic Plan pledge.

(ii) HSM Non-Principal Roads:

£18.25 million has been allocated to make further progress on the Non Principal Road Recovery Strategy and to undertake preparatory patching and surface dressing on local roads. This will help support the strategic pledge for ‘B’ roads maximise repairs to the more minor network.

(iii) Footways

Due to revenue budget restrictions general upgrades to footways will be only those funded by the allocation in this budget. Footways will be kept in a condition that is reasonably safe and commensurate with established usage. A large programme of footway slurry sealing is planned. As this is a cost effective treatment for repairing worn surfaces, it is hoped that a greater area of footway can be treated for the equivalent budget.

(iv) Structures

The increase in extreme weather events associated with the effect of global warming is having an increasingly damaging effect on DCC’s highway structures with failures of retaining walls, cuttings and embankments occurring on a regular basis. An increased proportion of the overall budget is therefore being targeted in this area in order to maintain connectivity on the network, and to address the disparity between the relatively good condition of the County’s bridges and the moderate condition of the retaining walls supporting the highway.

The programme of bridge strengthening continues where good value can be demonstrated by intervention before repairable deterioration takes place.

The programme to prioritise and assess the potential of scour on river bridges will continue with both targeted work on higher risk sites and detailed assessment to determine a forward programme on others.

The replacement of limited life components (mostly bearings and expansion joints) continues, with specific works being targeted on the A380 bridges as the useful working life of bearings and expansion joints comes to an end.

Corrosion protection to large metal ex-railway bridges now in the Council’s ownership and carrying cycle ways will continue this year as efforts continue to arrest deterioration of these structures.

The Asset Management Plan of all highway structures will continue to be refined by gathering more data and carrying out structural capacity assessments. This year special attention will be paid to detailed inspections of the Council’s stock of more modern post tensioned bridges, and investigation work to establish the safe management of sub standard structures.

(v) Street Lighting and Traffic Signals

A replacement programme for streetlight columns which have deteriorated through age will continue in association with work to reduce carbon footprint generated by Devon’s streetlights, however, due to limited funding such work will be prioritised and there may be instances where deteriorated columns are removed and not replaced until such time as funding becomes available. The opportunity will be taken, where possible to switch lanterns to part night lighting after consultation with Members and the police.

A significant proportion of Devon’s traffic signal equipment is approaching the end of its design life, and the Transport Asset Management Plan will programme its replacement. This will include the use of LED signal aspects, and extra low voltage systems, which have the benefits of greater light integrity, reduced power consumption, and consequently reduced revenue expenditure and carbon emissions.

8. Sustainability Considerations

When maintenance work is undertaken it is managed to ensure that the effect on the surrounding environment is kept to a minimum. On carriageways, surface treatment and reconstruction work is tightly controlled to achieve long term durability. Recycled materials and secondary aggregates are used whenever possible. A specific programme of recycling work was completed in 2012/13 and it is intended that all planings will be reused in the County's highway network. When surfacings incorporating primary materials are required, a durable low noise material such as stone mastic asphalt is considered.

9. Equality Considerations

No direct implications due to the capital budget at this time, but see the revenue report HTM/13/24 for implications following the reduction in revenue budgets.

10. Legal Considerations

No direct implications at this time.

11. Risk Management Considerations

The proposals contained in this report have been assessed and all reasonable actions are taken to safeguard the Council’s position.

The cumulative reduction in the revenue budget has significant implications for this capital allocation. Inability to undertake enough planned and general preventative maintenance work will result in an increased depreciation to the highways asset. This will lead to increased deterioration and defects and as a consequence safety will be compromised and third party claims may increase.

Where risks have been identified such as those associated with cost inflation or inclement weather, which could disrupt the capital programme by causing higher than anticipated costs or delays respectively, the implications have been taken into account in preparing this report. This includes the provision for reasonable contingencies in the estimates for capital highway and bridge maintenance schemes.

12. Options

The programme for 2013/14 optimises the use of the available funding to maximise repair work on the network. Any reduction in the programme would further compromise the County Council's ability to maintain the network in a reasonably safe condition and work towards the objectives of the DLTP, and the Council's Strategic Plan.

13. Reasons for Recommendation/Conclusion

The DfT capital settlement for 2013/14 provides funding towards the long term plan and gives further opportunity to help address the current backlog of outstanding highway maintenance work on both Principal and non Principal roads. However, it should be noted that it only provides funding to 63% of annual depreciation. It is also important that the capital funding for highway maintenance from central government is supported by a robust revenue allocation, as the commitment by the County Council is being monitored in this respect and could influence future capital settlements.
