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 2011/12 schemes detailed in Appendices I and II to this report be noted; (b) the strategy for delivery of the 2012/13 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 2011/12 and outlining the programme for 2012/13.

This is the second 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.

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 2011 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

The last three winters (2008/09 – 2010/11) have been more severe in terms of adverse weather events than any in the last 30 years. 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 gully 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/12/16).

In 2010 the Department for Transport made an additional £3.6m grant for roads where winter damage was evident. A further £9.3m was made available in 2011 for this purpose. Although this grant is not available in 2012/13, the additional £5 million in the revenue budget for work on C class and other minor roads, is a welcome addition to the programme.

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, in accordance with 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. We repaired nearly 120,000 in 2011. Therefore the upward trend appears 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 Councils’ own resources, but 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.

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.

The Cumbrian floods of 2009 alerted all local authorities to the strategic importance of highway bridges and structures, their contribution to maintaining communities, and their potential vulnerability when subject to extreme conditions. This has highlighted the need to ensure that limited budgets are focused on key areas, through effective asset management.

Significant progress has been made in gathering data as part of the Transport Asset Management Plan, enabling prioritisation of project work on structures to be identified in most areas. As increasing amount of data has now been gathered relating to the condition of the County’s highways structures – both bridges and more recently retaining walls. The condition of these structures is determined in accordance with national guidelines for inspection and assessment resulting in the calculation of an overall Structure Stock Condition Performance Indicator (SSCPI). The current condition of highway structures based on information collected to date is set out in Table 2 below.

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 £515 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. To stop this happening and keep the roads in their current overall condition would cost an average of approximately £57 million each year, as calculated by 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 of over 500 population 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 the 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 disparity between the general condition of bridges and retaining walls influenced the decision in 2010/11 to re-prioritising budgets and increase investment in retaining wall maintenance over the coming years. Currently, repairs are required to 1,490 retaining walls and 450 bridges to raise them to the ‘Good’ category.

The key priority in recent years has been to ensure that all structures on the principal road network are assessed and considered for upgrading to meet the 44 tonne gross vehicle weight capacity. Strengthening works to bridges on lesser categories of highway are being prioritised to be consistent with the maintenance principles adopted for the whole highway network. Currently 240 bridges have some strength deficiency and, where appropriate, are being managed using a risk-based approach developed by the Highways Agency, and adopted by the County Council.

With extreme weather events, particularly flooding, becoming more frequent there is an increasing need to carry out scour protection works to structures. Forward design on 7 schemes during 2011/12 will progress to the construction phase starting in April 2012. A further 15 will require works in subsequent years.

Work continues on the assessment of older structures, predominantly arches, where historic definitions of load bearing capacities have come into question following changes in design standards. These structural assessments are necessary to help identify and prioritise essential works and to best maintain and improve the condition of the bridge stock and include a number of County-owned bridges spanning live railways.

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. This includes protection works at road/rail proximity sites in conjunction with Network Rail.

A renewal and major maintenance programme has been put in place as a result of last year’s programme to inspect and assess essential bridge components, particularly bearings and joints.

6. HSM and BAS Programmes for 2011/12

The HSM and BAS LTP settlement for 2011/12 was £36.833 million.

Appendix I shows progress with the HSM programme for 2011/12.

Appendix II shows progress with the BAS programme for 2011/12.

7. HSM and BAS Programmes for 2012/13

Devon’s allocation for 2012/13 is £35.123 million.

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 :

£4.6m to specific larger schemes with a high Value for Money Index. These schemes will rectify carriageway with potential skidding defects and problems identified by the SCANNER survey.

£1.4m on surface dressing and preparatory patching works. This will surface dress carriageways in 2012/13 and prepare for the 2013 dressing programme.

Both will target “red” and “amber” SCANNER data and help to further stabilise NI168 and contribute to the County Council’s Strategic Plan pledge.

(ii) HSM Non-Principal Roads:

£19.1 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. This will also be supported by the additional funding of £5 million in the revenue budget for work on ‘C’ class and other minor roads.

(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 larger 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 existing national guidance on scour susceptibility has been reviewed. Site inspections of some 250 bridges were conducted and each bridge risk-ranked using standard methodology. Advance design is complete on the highest priority sites and protection works are programmed this year.

The replacement of limited life components (mostly bearings and expansion joints) continues, particularly on the A361 and A39. Some expansion joints are close to, or at, the end of their useful life.

Corrosion protection to large metal railway bridges, now in DCC ownership and carrying cycleways, will be implemented this year. It is anticipated that investment in these assets will be required over a number of years to arrest deterioration.

The programme of retaining wall strengthening and replacement works continue in order 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 Asset Management Plan of all highway structures will continue to be refined by gathering more data and carrying out structural capacity assessments. By applying highway condition and prioritisation factors a more integrated approach to maintenance of the whole network can be achieved.

(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 2011/12 and this will continue. 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/12/16 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 2012/13 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 2012/13 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 50% 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.
