! Metropolitan Borough of Wirral TECHNICAL SERVICES DEPARTMENT HIGHWAY MAINTENANCE POLICY David Green, Director Technical Services Department Town Hall Bebington Wirral CH63 7PT HMP-2005 1.0 INTRODUCTION 1.1 Delivering Best Value in Highway Maintenance - Code of Practice for Maintenance Management The code of practice for maintenance management was published in July 2001. The code is an advisory framework for highway maintenance which offers guidance and standards to achieve best value by way of specific objectives. Those objectives are:- 1.2 i) To encourage the development and adoption and regular review of policies for highway maintenance incorporating the principles of integrated transport, sustainability and best value. ii) To encourage participation by members of the community in the preparation of programmes and be responsive to their needs as users of the local highway network. iii) To adopt an efficient accountable and consistent approach to the collection of information relating to the highway infrastructure and its condition for both local and national purposes. iv) To continually review the technical and operational management regime in determining local practice and standards. Objectives of the Council’s Policy This policy has been written on the same basis and is established on the principle that highway maintenance and network management should be managed with the objective of delivering safety, serviceability and sustainability. These three objectives form the framework of a highway maintenance strategy which must be based on the ability to maintain the highway network for the safe and convenient movement of people and goods. The same three objectives also form the basis of an effective network management regime with the emphasis on:- iii) i) Network safety, i.e. complying with the statutory obligation of the authority and meeting users needs. ii) Network serviceability, i.e. providing effective management of the highway network asset by ensuring availability, maintaining reliability and integrity and enhancing quality. Network sustainability, i.e. maximising cost over time and value to the community in the choice of materials used, and maximising environmental contribution in the use of recycled materials. HMP-2005 2.0 LEGAL FRAMEWORK 2.1 Legal Requirements Duty of Care to maintain highways Maintainable at public expense Local Highway Authorities have a general duty of care to users and the community to maintain the highway in a condition fit for its purpose. Section 41 of the Highways Act 1980 imposes a duty on local Highway Authorities to maintain highways maintainable at public expense. HMP-2005 3.0 STRATEGY AND HIERARCHY 3.1 Highway Maintenance Strategy The principles of an effective Highway Maintenance Strategy should include:i) ii) iii) iv) v) vi) vii) a detailed inventory of all components of the network a statement of highway maintenance policies and procedures a defined hierarchy for all elements of the network to meet the needs of the highway user a consistent approach for inspecting, recording, prioritising and programming maintenance works the effective use of limited resources to achieve safety, serviceability and sustainability procedures for dealing with the implications of winter service operations, statutory utility works, deficient drainage systems and the planning of major/minor highway improvement/reconstruction schemes on the availability of the network to the user the effective management of the Council’s contractors operations in relation to:a) b) c) d) e) 3.2 surfacing and reconstruction schemes street lighting repairs and renewal highway drainage minor works and gully cleansing traffic signal maintenance grounds and tree maintenance Network Hierarchy The code recommends the importance of ensuring that the hierarchy for both carriageways and footways adopted by the authority reflects the needs, priorities and actual use of each road in the network. This policy has incorporated the recommendations of the code in determining the categories for both carriageway and footway hierarchies and taken into account local circumstances such as the influence of schools, hospitals and facilities for the elderly and less able. 3.2.1 Carriageway Hierarchy This policy categorises the carriageway hierarchy description in the following way. a) Category 1 – Strategic Route – Principal A road between primary destinations; a route for fast moving traffic with little frontage access or pedestrian traffic. Parked vehicles are prohibited and there are few junctions. The A41 Rock Ferry/New Ferry By Pass falls into this category. b) Category 2 – Main Distributor – Primary urban network – Short-medium distance traffic; speed limits are usually 40 mph or less, parking is restricted at peak times and there are positive measures for pedestrian safety. The following therefore are all considered to be category 2 roads. A41 – New Chester Road, Chester Street, Canning Street A540 – Chester Road, Telegraph Road, Column Road, Grange Road, Meols Drive A553 – Market Street, Birkenhead Road, Hoylake Road, Fender Lane, Bidston By-Pass, Hoylake Road, Laird Street, Park Road North Conway Street HMP-2005 A5137 – Brimstage Road A551 – Barnston Road, Arrowe Park Road, Upton By-Pass, Upton Road, Pasture Road, Leasowe Road A552 – Woodchurch Road, Singleton Avenue, Borough Road A5029 – Whetstone Lane, Exmouth Street, Watson Street, Tower Road A554 – Birkenhead Road, Church Road, Brighton Street, King Street, Seabank Road, Rowson Street, Kings Parade, Bayswater Road, North Wallasey Approach, Bidston Link Road A5139 – Docks Links North and South Dock Road A5027 – Upton Road, Park Road North, Duke Street, Gorsey lane c) Category 3 – Secondary Distribution – Classified roads, bus routes carrying local traffic with frontage access and frequent junctions. In urban areas these roads have predominantly 30 mph speed limits and high levels of pedestrian activity with some crossing facilities including zebra, pelican crossings etc. onstreet parking is generally unrestricted except for safety reasons. The following roads therefore fall into the secondary distributor category. B5151 – Mount Road, Storeton Road, Ingestre Road, Talbot Road, Bidston Road, Boundary Road A5030 – Cleveland Street B5147 – Argyle Street, Clifton Crescent A5058 – Poulton Bridge Road B5145 – Breck Road A551 – Wallasey Village B5477 – Wallasey Village, Harrison Drive B5139 – Greasby Road, Frankby Road, Blackhorse Hill d) Category 4 – Link Road – Roads linking the main and secondary network with frontage access and frequent junctions. In urban areas they are residential or industrial roads with 30 mph speed limits random pedestrian movements and uncontrolled parking. The following roads can be considered to be link roads. Old Hall Road, Stadium Road, Thermal Road, Pool Lane B5137 - Croft Drive East, Spital Road, Brimstage Road B5136 – Church Road, The Village Claughton Road, Park Road, South Park Road West HMP-2005 Oxton Road, Woodchurch Road B5144 – Kelvin Road, Wheatland Lane A551 – Mainwaring Road, Liscard Road, Wallasey Road, St Hilary Brow A551 – Borough Road A5145 - Poulton Road B5143 – Rake Lane, Rowson Street B5146 – Corporation Road A5030 – Beaufort Road A5058 – Wallasey Bridge Road Saughall Massie Road, West Kirby Road Saughall Massie Road Pump Lane, Heron Road B5138 – Pensby Road B5141 – Village Road, Sandy Lane, Banks Road, Heath Road, Teehey Lane, Kings Road, Borough Road e) Category 5 – Local Access Roads – Roads serving limited numbers of properties carrying mostly access traffic. In urban areas they are minor link roads such as residential roads or cul de sacs. This description covers the remaining 85% approx. of the local highway network. 3.2.2 Footway Hierarchy The Code advises that footway maintenance standards will not necessarily be reflected by the classification of the road it serves. It is more likely to be determined by factors such as:a) b) c) d) e) Pedestrian volume; usage and proposed usage. Accident and other risk assessment. Age and type of material in footway. Character and traffic use of adjoining carriageway. Local factors, proximity of schools, age and distribution of population, medical centres, hospitals, government offices etc. 3.2.3 This policy categorises the local footway hierarchy in the following way. a) HMP-2005 Category 1A Prestige Walking Zone, these are prestige areas in towns and cities with exceptionally high usage. Currently there are no footways in the Borough which meet this classification but the planned redevelopment of areas such as Grange Road in Birkenhead may result in the reassessment of this category. b) Category 1 Primary Walking Route, normally busy shopping and business areas, or links to railway or bus stations. There are a number of primary walking routes in the Borough which are listed below and these routes are inspected for safety purposed on a monthly basis. Market Street Grange Road Dee Lane The Crescent Banks Road Hoylake Road Upton Road/Hoylake Road Wallasey Road Seaview Road Liscard Village Liscard Road Liscard Way Pasture Road Hoylake Road Victoria Road Woodchurch Road Grange Road Grange Road Grange Road West Oxton Road Whetstone Lane Oliver Street St Johns Street Catherine Street Exmouth Street New Chester Road Bebington Road New Ferry Road Allport Lane The Precinct Telegraph Road The Mount Pensby Road c) Kings Gap to Hoyle Road Riversdale Road to Westbourne Road Grange Road to South Parade Grange Road to Banks Road Dee Lane to South Road Upton Road to Borrowdale Road Sandbrook Lane to Rosslyn Drive Belvidere Road to Seaview Road Wallasey Road to Thirlmere Drive Seaview Road to Queen Street Liscard Crescent to Martins Lane Liscard Village to Mill Lane Maryland Lane to Hoylake Road at (Knutsford Road) Sandbrook Lane to Upton Road Rowson Street to Victoria Parade Osmaston Road to Temple Road Argyle Street to Grange Pavement St Johns Street to Grange Road West Grange Road to Cole Street Balls Road to Grange Road West Borough Road to Grange Road Exmouth Street to St Johns Street Claughton Road to Grange Road Claughton Road to Grange Road Grange Road to Claughton Road Sefton Road to Boundary Road Boundary Road to New Chester Road New Chester Road to Salisbury Drive The Cross to June Avenue Planter Legion Lane to The Rake Tesco’s entrance to Boundary Lane Telegraph Road to Mount Avenue Telegraph Road to May Road Category 2 Secondary Walking Route, routes with medium usage through local areas feeding to primary routes, local shopping centres large schools and industrial areas etc. This type of footway is inspected every 3 months and the locations are as follows. Saughall Massie Road Arrowe Park Road The Village Hoole Road Gilroy Road Greasby Road Greasby Road Town Meadow Lane St Albans Road Mill Lane Trafalgar Road King Street Twickenham Drive Wallasey Village Leasowe Road Hoylake Road HMP-2005 Brookside Crescent to Brookside Crescent The Village to Rake Lane Arrowe Park Road to Church Road Outside shops Greenbank Road to Gilroy Road Well Lane to Macdonald Drive Highfield Drive to Broadway Maryland Lane to Mallard Way Wallasey Road to Mill Lane Liscard Road to Woodstock Road Serpentine Road to King Street Trafalgar Road to Tobin Street Cameron Road to Cook Road Grove Road to Perrin Road Wallasey Village to Railway bridge (both sides) Reeds Lane to Sandbrook Lane Rowson Street Rake Lane Seabank Road Brighton Street Liscard Road Borough Road Poulton Road Claughton Firs Arrowe Park Road Fleetcroft Road Home Farm Road Pensby Road Old Chester Road Old Chester Road Bebington Road Bedford Road Old Chester Road Bebington Road Greenway Road Church Road Argyle Street South Borough Road Borough Road Hoylake Road St James Road Laird Street Upton Road Upton Road Balls Road Clifton Crescent Conway Street Argyle Street Hamilton Square Market Street Duke Street Laird Street Europa Boulevard Derby Road Clifton Avenue Mill Park Drive Eastham Rake New Chester Road Eastham Village Road Allport Road Church Road The Wiend Bromborough Road The Village Cross Lane Heath Road Bebington Road Village Road Teehey Lane Town Lane Old Chester Road Bebington Road Village Road Downham Road South Milner Road Irby Road Thingwall Road Pensby Road (1) Pensby Road (2) HMP-2005 Seabank Road to Magazine Lane Magazine Lane to Sandfield Road Magazine Lane to Holland Road Tobin Street to Brougham Road Parkside to Lumley Road Brighton Street to Poulton Road Borough Road to Mill Lane Christchurch Road to Fairview Road Pool Lane to Woodchurch Road Church Lane to Crewe Green Shop area only Wimbourne Avenue to Richmond Way Woodburn Boulevard to Bebington Road Bebington Road to Farlow Road Old Chester Road to The Cokers Grove Road to New Chester Road Grove Road to Downham Road Kirkland Avenue to Mount Road Mount Road to Derby Road Whetstone Lane to Bebington Road Outside station Prenton Road West to Kingsland Road Balls Road East to Clifton Crescent Gautby Road to St James Road Hoylake Road to Hoylake Road St James Road to Mallaby Street Noctorum Avenue to Wirral Way Woodsorrel Road to Alderley Road Slatey Road to Oxton Road Borough Road to Argyle Street Exmouth Street to Argyle Street Clifton Crescent to Hamilton Square All Argyle Street to Hamilton Street Park Road North to Beckwith Street Mallaby Street to Park Road North Price Street to Conway Street Greenway to Whetstone Lane Eastham Rake to Mill Park Drive Eastham Rake to Crossthwaite Avenue Mill Park Drive to New Chester Road Eastham Rake to Adaston Avenue New Chester Road to Church Lane Slip roads in front of shops Quarry Avenue to The Village Church Road to Bromborough Road Church Road to The Wiend Church Road to Townfield Lane Heath Road to Stanton Road Cross Lane to Norbury Avenue Boundary Road to Old Chester Road Mount Road to Teehey Lane Higher Bebington Road to end of service road Teehey Lane to Roland Avenue Oak Road to Bebington Road Old Chester Road to The Village School Hill to The Lydiate Telegraph Road to Milner Road Downham Road South to Oban Drive Fishers Lane to service road Irby Road to Roslin Road Rosemead Road to Marks Way Fishers Lane to Ridgewood Drive d) The two remaining categories are:Category 3 Link Footway – linking local access footways through urban areas, i.e. routes through housing estates etc. and Category 4 Local Access Footway – associated with low usage; i.e. in short estate roads and cul de sacs. HMP-2005 4.0 Highway Inspections 4.1 Inspection, Assessment, Recording and Repair 4.1.1 Inspections The code emphasises the need for an effective regime of inspection, assessment and recording as the most crucial component of highway maintenance. The inspection, assessment and recording regime should provide the basic information for addressing the key objectives of highway maintenance strategy:Network Safety (Safety Inspections) Network Serviceability (Service Inspections) Network Sustainability (Structural Condition Survey) All elements of the inspection and assessment regime should be applied systematically and consistently, particularly in the case of network safety, where information may be relevant in respect of legal proceedings. 4.1.2 Highway Safety Inspections The code states that this type of inspection consists of frequent comprehensive inspections to identify all defects likely to create danger or inconvenience to users of the network or the wider community. The recommended parameters which need to be specified for a safety inspection regime are:i) ii) iii) iv) Frequency of inspection Items for inspection Degree of deficiency Nature of response This policy outlines the Authority’s current safety inspection regime and expands on the above parameters. 4.1.3 Carriageway Inspections As outlined earlier in the network hierarchy section of this document the carriageway network has been divided into five categories and the inspection frequencies are as follows. i) Strategic Route, a driven inspection is undertaken quarterly. ii) Main Distributors, certain sections of these routes are inspected on foot monthly or quarterly depending on the inspection frequency of the adjacent footways. In addition, all these particular routes are inspected by vehicle quarterly. iii) Secondary Distributors, certain sections of these routes are inspected on foot quarterly again depending on the inspection frequency of the adjacent footways, the remainder being inspected on foot annually. Driven inspections undertaken quarterly supplement this inspection regime. iv) Link Roads, all link roads are inspected on foot annually and driven inspections quarterly. v) Local Access Roads are inspected on foot annually. HMP-2005 4.1.4 Footway Inspections As indicated earlier in this document the frequency of safety inspections on footways is dependant predominantly on pedestrian volume. However, the majority of footways in the Borough are link or local access footways. Linking footways are routes which link local access footways through urban areas. Local access footways are associated with low usage and are normally found on short estate roads and cul de sacs on housing estates. These two categories of footway are inspected annually on foot and a full safety and service inspection is carried out at the same time. Although pedestrian volume may not be as great as on other footway routes this category of residential footway is subject to considerable misuse by vehicle overriding and damage by utility companies. In certain locations both of the above factors have resulted in an increase of public liability insurance claims and particular attention is now given to the following items when safety inspections are undertaken. a) Age and condition of footway construction The majority of public liability insurance claims arise from trips in flagged footways. Paving flags as a footway surfacing material is a long standing well established method of construction. Providing the flagging remains undisturbed it is a relatively maintenance free surface. However, when it is removed by Utility companies as part of possible mains renovation work it is not always reinstated to the required standard. If this footway is subject to vehicle overriding the flags can break and become uneven and can soon be a tripping hazard for pedestrians. In order to reduce this potential source of claims the Authority has now introduced within the structural maintenance programme the phased replacement of flagged footways with tarmacadam. The Authority’s regulation and enforcement of Utility company operations is referred to later in this document. This type of footway in certain areas of the Borough can also be affected by tree roots. In areas where isolated tree root damage can lift paving flags small areas of paving flags are removed and replaced with tarmacadam, and in some cases depending on arboricultural advice the tree roots are also cut back at the same time. In locations where a large number of trees exist it has been and will be necessary in the future to remove large areas of paving flags and replace with tarmacadam. 4.2 Assessment The Authority uses the definition of damage as specified in “The Highway Authorities Definitions of Damage to Highways and Pavements” in the Hundred Association Report (H.A.D) as the basis for prioritising work within the Authority. i) HMP-2005 The specified definition of actionable damage in carriageways is a sharp edged depression (pothole) of 40mm or greater in depth and extending in any one direction for more than 300mm. The report states that damage is defined as a defect in the carriageway which impairs the value or usefulness of the carriageway and provides a safety hazard for road users. ii) The specified definition of actionable damage in footways is trips of more than 20mm, rocking paving flags greater than 20mm and a rapid change in footway profile greater than 25mm and extending in plan dimension less than 600mm. The report states that damage is defined as a defect in the footway which impairs the value or usefulness of the footway and provides a safety hazard for pedestrians. iii) 4.3 The Authority includes a further criterion of missing iron work as an actionable defect. Repairs During safety inspections all observed defects should be recorded as the degree of deficiency is important in determining the nature and speed of response. The Authority has four levels of priority. Priority 1 – Defined as a hazard that should be corrected or made safe at the time of the inspection if reasonably practicable. This category can allow for the making safe or temporary repair within 24 hours if permanent repair is not possible. Any permanent repair should be carried out within 28 days. Examples of such instances are vehicle damage to street furniture, lamp columns, traffic signals etc. or subsidence within or effecting the highway. Priority 2 – Defined as a defect to be repaired within a planned programme depending on the degree of deficiency, traffic levels and site characteristics. The necessary repairs are to commence within 7 days and be completed within 28 days. HMP-2005 An example of this type of priority situation is where a defect has been observed during a safety inspection which a highway inspector considers will become a hazard as a result of gradual deterioration. The likely location is route well used by highway users. Priority 3 – Defined as a repair where the deficiency of the defect requires the works to be substantially complete within 28 days. Examples of this type of priority would be a defect of 20mm or above in footways in a location likely to be used by pedestrians. Carriageway defects of 40mm or above depending on the location of the defect and road markings of less than 35% visibility. 4.4 Structural Condition Surveys 4.4.1 U.K.P.M.S Survey Requirements The United Kingdom Pavement Management System (UKPMS) is a management system which, using visual inspection, provides a comprehensive picture of the condition of the asset. The visual inspections are generally carried out to produce Best Value Performance Indicators (BVPI’s). However, the information provided from these surveys is primarily used to assist with identifying and prioritising Highway Maintenance schemes. There are two types of survey currently used. Course Visual Inspections (CVI) – The CVI is the more widely used surveying process as it is a relatively fast, course survey, giving a cost effective method of assessing the “course” condition of a highway network from a slow moving vehicle. Detailed Visual Inspections (DVI) – Is a much slower process as it is carried out on foot, and is used to survey specific sites that require further investigation identified from previous surveys. The automated processing of UKPMS provides the key function of translating recorded highway condition across the network to a prioritised schedule of treatment lengths with a recommended treatment option and an associated cost for each length. 4.5 Service Inspections The code recommends that service inspections in contrast to safety inspections should be focussed on ensuring that the network meets the needs of users and deals with specific inspections of particular highway elements within the network. They may be undertaken separately to safety inspections and less frequently but are designed to identify deficiencies in the reliability and quality of the network. Service Inspections on footways are normally carried out in two ways, either as part of the safety inspection or in response to a highway related enquiry. Service Inspection should not be used as a defence in public liability insurance claims but should form part of a programmed maintenance strategy. The principal objectives of this form of inspection are to:i) ii) iii) iv) HMP-2005 ensure availability achieve integrity maintain reliability enhance quality By providing information regarding the condition of items such as:i) ii) iii) iv) v) vi) road markings pedestrian guardrails street seats street nameplates highway drainage highway signs It is possible to incorporate any defective items in a programme of serviceability maintenance work subject to funding. Service Inspections can also cover the following operational areas:Highway drainage systems Embankments and cuttings Landscaped areas and trees Carriageways, footways cycleways and network integrity Fences and barriers Traffic signs and bollards Road markings Traffic signals, pedestrian and cycle crossings Street lighting Bridges and structures Structural condition surveys 4.6 Highway Drainage Systems The maintenance of the Council’s highway drainage assets is procured through the Highway Drainage Minor Works and Gully Cleansing Contract. There are approximately 60,000 gullies in the Borough of differing types and sizes and approximately 7000 linear metres of drainage channel located within the adopted highway. The assets are inspected and cleaned twice a year. The inspections also identify any defect which presents any risks to health and safety, these contractual inspections are also supplemented by the Council’s highway inspection regime. 4.7 Landscaped Areas and Highway Verges The maintenance of the Council’s highway verges, highway shrubberies and certain landscaped areas is procured through the Streetscene Service’s Ground Maintenance Contract. The contractor is required to maintain approximately 2.2 million square metres of grass, 47,000 metres of hedging, 88,000 square metres of shrubs, roses and woodland planting and some 1.3 million square metres of weedspraying. The frequencies of maintenance for each individual unit is specified in the Contract. 4.8 Trees The maintenance of the Council’s 16,000 highway trees is procured through the Streetscene Services Arboriculture Contract. The contractor is required to provide a 10 year cyclical maintenance programme based on a initial condition survey of each tree. HMP-2005 The contractor also provides a 24 hour, 365 days a year emergency call out service covering severe weather conditions, dangerous trees caused by road traffic accidents and other similar events. 4.9 Cycleways The maintenance of the Council’s off road cycleway network is funded from the Highway Maintenance Structural Maintenance Programme. The total length of the network is 11.8K.m. and it is proposed to inspect each of the 7 routes 3 times a year, in Spring, mid Summer and late Autumn. 4.10 Traffic Signs A comprehensive survey of all permanent existing traffic signs is in progress in order to record the locations of all illuminated and non-illuminated traffic signs in the Borough. The survey will identify the type of sign, the condition of the sign, the supporting post and in the case of illuminated signs the condition of the lantern and associated brackets. The results of the survey will be analysed to determine the overall condition of the traffic sign assets and whether certain signs can be removed to reduce sign clutter. 4.11 Winter Maintenance In addition to the Council’s statutory duty to maintain highways maintainable at public expense, section 111 of the Railways and Transport Safety Act 2003 imposes a further duty on the Council to ensure that where reasonably practicable, safe passage along a highway is not endangered by snow or ice. The Council’s winter maintenance service involves:i) ii) pre-treating the highway to prevent ice forming post-treating the highway when ice has formed or snow has accumulated. 24 hour monitoring of forecasts ensures current weather conditions are known throughout the winter maintenance period which normally extends from midNovember to early April. Pre-treatment is carried out on agreed routes comprising:Principle roads (Class “A” and “B” roads). Other strategic main roads. Major bus routes notified by bus operators. Known problem locations and hazardous gradients. Post-treatment of the agreed routes will be carried out during and after snowfall. Footways are only treated once snow has settled or during prolonged freezing conditions and these will be treated on a priority basis including:i) ii) iii) 4.12 town centre shopping areas schools during term time other footways where an inspection confirms the necessity for treatment. Street Lighting The Council’s street lighting maintenance policy is:i) HMP-2005 carry out fortnightly inspections of the street lights at night and to attend to any defective lights within 3 days ii) iii) to provide the facility for the public to report defective lights and for these also to be attended to within 3 working days to carry out periodic testing for the purpose of assessing the electrical and structural integrity of the lighting system. The Council’s street lighting renewal and improvement policy is:To install new lighting in compliance with BS5489. To allocate available funding for improved lighting by reference to a list of nominated locations, prioritised on merit relative to environmental factors and stock condition. 4.13 Operation of the New Roads and Street Works Act 1991 The Highway Authority has specific duties to ensure that utilities comply with the requirements of the Act and that the works are carried out in a co-ordinated manner with all other works and events affecting the highway. The Authority is also required to maintain a street works database recording all works notified by utilities and the Authority’s own works. A gazetteer of all streets and maintenance categories also has to be maintained and updated quarterly. In order to ensure compliance with the various Codes of Practice, sample inspections are carried out by Highway Inspectors in accordance with the Code of Practice for Inspections. This requires that 10% of all works are inspected in three categories giving a total of 30% per annum. Routine and investigatory inspections, (other than sample inspections) are carried out by Highway Inspectors during their normal inspection duties. Any defective works are reported to the Street Works Section for action. Sample inspection fees are charged quarterly in arrears and defect inspection fees charged monthly in arrears in accordance with the Code of Practice. 4.13.1 Section 74 Charges The Act empowers the Authority to charge utilities for the unreasonable occupation of the highway i.e. when works overrun their estimated completion date. The Authority inspects a number of sites, mainly on priority routes to minimise delays for highway users. HMP-2005
