<strong>Flooding</strong> <strong>Drainage</strong> & <strong>Watercourses</strong><br />

Reasons for the review<br />

1. On 10 December 2007, further to a resolution of <strong>County</strong> <strong>Council</strong>, the<br />

Overview and Scrutiny Committee commissioned a Select Committee to<br />

examine the issue of flooding issues, particularly as they relate to the<br />

maintenance of drainage systems and watercourses.<br />

2. The aim of the review was stated to be “To consider why areas of<br />

<strong>Nottinghamshire</strong> were so badly affected by flooding in July; if the effects<br />

could have been less severe or prevented through better maintenance of<br />

local drainage systems and watercourses and what measures can be put in<br />

place to prevent a reoccurrence in the future. To look at what systems were<br />

in place to assist those affected and how these could be improved in the<br />

future should high levels of flooding happen again.”<br />

Overview of the Summer Floods<br />

3. On 28 January 2008, the Select Committee received a briefing from John<br />

McGuigan, Emergency Planning Manager which provided an overview of the<br />

summer floods of 2007 in <strong>Nottinghamshire</strong>. Mr McGuigan explained the<br />

widespread nature of this pluvial flooding (i.e. flooding from severe rain)<br />

which overwhelmed drains and watercourses resulting in substantial damage<br />

to domestic properties, businesses, schools and the local infrastructure, such<br />

as, roads, electrical substations and sewage works.<br />

4. Mr McGuigan gave numerous examples of the misery caused by this<br />

unprecedented flooding, including North Leverton with Habblesthorpe where<br />

an electrical substation was flooded, members of the public had to be<br />

evacuated from their homes and the local primary school has still not reopened.<br />

5. In Little Carlton, flood damage to homes was made worse by sewage<br />

backing up into properties; while at Southwell Races the racetrack was “torn<br />

up” by the effect of the water, resulting in severe financial loss. Another of<br />

the worst hit villages was Lowdham where over 200 properties were flooded.<br />

6. Across the whole county the number of flooded properties was as follows:<br />

• Ashfield DC 61<br />

• Broxtowe BC 6<br />

• Bassetlaw DC 801<br />

• Gedling BC 53<br />

• Newark & Sherwood DC 470<br />

• Mansfield DC 20<br />

• Rushcliffe BC 0<br />

7. Mr McGuigan also pointed out that fat being put down drains was a problem<br />

that could exacerbate flooding. In addition there was a need to develop a<br />

sandbag policy with district councils (see section on sandbag policy below).<br />

5


8. Further to this presentation, on 25 February Mr McGuigan briefed the select<br />

committee on the multi-agency response to the summer floods. Some<br />

agencies have a pro-active responsibility to prevent flooding taking place<br />

others are reactive and reduce the damage caused by flooding. By<br />

concentrating on being pro-active the response phase may be lessened. The<br />

responsibilities of the various agencies are detailed below:<br />

9. <strong>Nottinghamshire</strong> Police:<br />

• Coordinate the emergency response<br />

• Assist in rescue/recovery of casualties<br />

• Assist with evacuation of property<br />

• Establish appropriate cordons<br />

• Coordinate the response to the media<br />

• Close the highway where necessary<br />

• Protection and security of evacuated premises<br />

• Traffic management<br />

• Casualty Bureau<br />

• Conduct criminal investigation when necessary<br />

The casualty bureau can be set up as necessary and is based at Hucknall<br />

Police Station. Police resources utilised during the summer floods included<br />

the helicopter used at North Leverton. The police also took action regarding<br />

a farmer who went missing in Attenborough.<br />

10. <strong>Nottinghamshire</strong> Fire and Rescue Service:<br />

• Save life, rescue and assist in recovery of casualties<br />

• Pump out premises/land where appropriate<br />

• Support incident command<br />

• Provide health and Safety<br />

• Support Media Response<br />

One of the difficulties encountered by the Fire and Rescue Service during the<br />

summer floods was that there was nowhere to pump the water – one<br />

instance of this took place in Lowdham.<br />

11. <strong>Nottinghamshire</strong> <strong>County</strong> <strong>Council</strong>:<br />

• Planning and preparation<br />

• NCC Incident co-ordination<br />

• Warning and informing<br />

• Managing accommodation for evacuees<br />

• Responsible for surface water drainage<br />

• Providing sandbags / pumps for flood alleviation / clear drains / culverts<br />

• Provide boats on request<br />

• Identifying vulnerable people<br />

• Co-ordinate recovery.<br />

The <strong>County</strong> <strong>Council</strong> is responsible for the multi-agency flood plan. The<br />

<strong>County</strong> <strong>Council</strong> does not have a duty to provide sandbags to all domestic<br />

properties at risk of flooding.<br />

6


12. District/Borough <strong>Council</strong>s:<br />

• Assist with flood alleviation such as issuing sandbags, clearance of<br />

blocked culverts, dealing with flooded roads and traffic diversions<br />

• Provide equipment, information, personnel and expertise to assist the<br />

emergency services<br />

• Provide emergency care for those who have been evacuated or those<br />

affected by flooding but remaining in their home<br />

• Provide environmental health advice<br />

• Support the recovery of the community.<br />

One of the most vital aspects of the function of Districts and Boroughs is<br />

around environmental health advice – particularly relevant to home owners<br />

who have suffered from backed up sewage.<br />

13. The Environment Agency:<br />

• Issue flood warnings<br />

• Maintain flood defences<br />

• Provide pumps when necessary<br />

• Liaise with community via Flood Wardens<br />

• Monitor water levels and advise as necessary<br />

• Support the media response<br />

• Support incident command.<br />

The Environment Agency can also assist with the provision of sandbags,<br />

subject to availability of resources not otherwise engaged on the above<br />

priority areas of work (note – The Environment Agency has no responsibility<br />

to provide sandbags to the general public).<br />

14. Internal <strong>Drainage</strong> Board:<br />

• Levying of drainage rates, their collection and keeping accounts<br />

• Maintenance of drains, pumping stations and flood defences serving<br />

notices<br />

• Environmental improvement<br />

• Promotion of capital schemes for drainage and flood defence<br />

improvement<br />

• Emergency response during flood by providing staff, resources and local<br />

knowledge<br />

• Public relations<br />

• Dealing with planning applications (discharge consents and flood risk<br />

assessments)<br />

• Flood records and post-flood survey<br />

Internal <strong>Drainage</strong> Boards have a number of responsibilities under the Land<br />

<strong>Drainage</strong> Act 1991, including the authority to deepen, widen straighten or<br />

improve watercourses within their area and to serve notice on riparian<br />

owners that they will be carrying out works and charging for them.<br />

15. Utility Companies:<br />

• Secure services and equipment to ensure continuity of supply<br />

7


• Repair services disrupted by flood events<br />

• Provide alternative means of supply during service disruption<br />

• Advise local authorities and communities when services will be reinstated<br />

Utility companies will bring in their own sandbags and pumping resources.<br />

16. The Select Committee noted the complex interlocking nature of the multiagency<br />

response and concluded that agencies’ responsibilities and contact<br />

details should be better publicised.<br />

Sandbags Policy<br />

17. Rob Fisher, Head of Emergency Management and Registration briefed the<br />

select committee on the usage and limitations of sandbags on 25 February.<br />

Mr Fisher re-emphasised that there is no duty for local authorities to protect<br />

properties with sandbags. Sandbags are not the easiest of materials to work<br />

with – the <strong>County</strong> <strong>Council</strong> maintains its stock of sandbags for holding down<br />

temporary road signs in the wind. The mass transportation of sandbags into<br />

flooded areas may be problematic in any event. However, sandbags can<br />

divert shallow flowing water – if it has somewhere to go. They can also<br />

protect homes from the wash caused by vehicles driving through floodwater.<br />

During the summer floods over 150,000 sandbags were issued across the<br />

county.<br />

18. West Sussex <strong>County</strong> <strong>Council</strong> operates a policy of only supplying sandbags to<br />

residential properties being flooded from the highway. Where properties are<br />

at risk of flooding from a watercourse, residents are directed to procure their<br />

own sandbags from a builders’ merchant.<br />

19. At a <strong>Nottinghamshire</strong> sandbag depot security guards had to be employed to<br />

prevent members of the public collecting sandbags – the numbers of people<br />

were causing access problems for staff. There have also been instances<br />

where sandbags deployed near watercourses have been removed and placed<br />

by residents outside their homes. There have even been incidents where<br />

people have attempted to sell sandbags on e-bay.<br />

20. In conclusion, Mr Fisher explained that sandbags were not a panacea to<br />

flooding events. There are other products – such as air brick covers and<br />

floodgates which are more effective.<br />

21. Ian Harrison, the Resilience Manager at Newark and Sherwood District<br />

<strong>Council</strong> also contributed to the select committee’s briefing on sandbags<br />

policy. Mr Harrison stated that although sandbags provided a limited benefit<br />

they were a tangible overt response which helped the confidence of<br />

communities and flood victims. However, with flash flooding there was a<br />

difficulty in deploying sandbags in time. In addition, the deployment policy is<br />

based on risk not request and this presents difficulties in terms of negative<br />

feedback.<br />

22. Newark and Sherwood District <strong>Council</strong> has also undertaken trial use of<br />

“Acqa” silicon granule sacks, which can be stored flat and dry until needed –<br />

when they can be distributed to isolated and vulnerable properties. “Acqa”<br />

silicon bags cost only £3.<br />

8


23. The select committee noted an area of possible policy development around<br />

the strategic storage of sandbags near where they are likely to have to be<br />

used in order to overcome the logistical problem. There were also awareness<br />

raising issues for the public around the limitations of sandbags (and the<br />

superior alternatives) and the potentially anti-social nature of driving at<br />

speed through floodwater thereby exacerbating the flooding with bow<br />

waves.<br />

Newark & Sherwood Resilience Programme<br />

24. Ian Harrison explained that the resilience programme in Newark and<br />

Sherwood supported principles around “community” and cohesion and can<br />

be used to support resilience to all threats.<br />

25. Corporate promotion of resilience at Newark & Sherwood includes: the<br />

<strong>Council</strong>’s assessment of strategic risk, strict compliance with planning policy<br />

guidance (e.g. PPG/PPS 25) and building control around business and<br />

domestic development and extensions.<br />

26. Newark and Sherwood’s wider promotion of resilience includes annual risk<br />

and resilience conferences and workshops, events at the Newark & Notts<br />

Show, facilitation of a flood fair in Lowdham, training for volunteers and a<br />

partnership with flood proofing companies.<br />

27. Newark and Sherwood District <strong>Council</strong> has also entered into a partnership<br />

scheme with DEFRA and the Environment Agency which has resulted in 17<br />

high risk properties in Gunthorpe being flood proofed and £90,000 being<br />

made available for work on 15 properties at risk at Bleasby and Gibsmere<br />

(NB – this scheme relates to properties at risk from river flooding rather<br />

than flash flooding caused by severe rain).<br />

28. Mr Harrison also reported that a Risk and Resilience Conference which took<br />

place on 4 th October 2007 supported the following options:<br />

• Watercourse mapping and condition survey (with maps passed to Parish<br />

<strong>Council</strong>s<br />

• Watercourse monitoring by local volunteers<br />

• Provide information on who does what<br />

• Deployment of local resources including sandbags, stores, signs etc.<br />

29. The Select Committee noted these options and observed that existing<br />

groups (e.g. Neighbourhood Watch) could provide a ready pool of volunteers<br />

for monitoring watercourses.<br />

Highway <strong>Drainage</strong><br />

30. Andy Wallace, <strong>Drainage</strong> Manager, provided information to the Select<br />

Committee about Highway drainage issues. Mr Wallace explained that<br />

highway gullies are emptied just once a year. The <strong>County</strong> <strong>Council</strong> made the<br />

decision to reduce to once a year from twice a year (or even once a quarter<br />

in some areas) in 1998. There is also more debris and litter entering gullies<br />

because of less sweeping by District <strong>Council</strong>s. The cost of gully emptying<br />

and drain cleaning is put at £600,000 per year.<br />

9


31. Gullies connect into highway drains and then into Severn Trent sewers,<br />

watercourses or soakaways, alternatively they can connect directly into<br />

Severn Trent surface water sewers, combined Severn Trent foul and surface<br />

water systems or directly to private estate systems. There are often no<br />

proper records relating to these systems.<br />

32. The <strong>County</strong> <strong>Council</strong>’s Highway <strong>Drainage</strong> Assets include nine highway<br />

drainage pumping stations – which can be subject to different inspection<br />

regimes – and a large number of culverts carrying watercourses across the<br />

highway. Where there are ditches or drains these are often the responsibility<br />

of the adjacent land-owner.<br />

33. The immediate highway cost in dealing with the flooding was £1,071,000.<br />

The capital highway costs to deal with the consequences of flooding are, for<br />

2007/08, £941,000 and for 2008/09 £1,345,000.<br />

34. In order to address highway drainage issues the <strong>County</strong> <strong>Council</strong> has already<br />

appointed a <strong>Drainage</strong> Manager (in line with recommendations of the Pitt<br />

Review into the summer 2007 floods). In addition, the Authority has<br />

purchased a specialist drain cleaning vehicle which has been used to clear<br />

119 drain blockages (since its introduction in August 2007 up to early March<br />

2008). It is interesting to note that 16 of the 119 problems were caused by<br />

drains being damaged by utility works i.e. utility companies laying cables or<br />

pipes.<br />

35. The outstanding issues for highway drainage are as follows: there is no<br />

investment in capital drainage improvements and a lack of capacity in<br />

existing systems. This is combined with the effects of climate change and<br />

increased intensity and frequency of storms.<br />

36. The Select Committee noted the reduction in the frequency of gully<br />

emptying on cost grounds and felt that there would be great benefit in<br />

instituting a spring and autumn clean of gullies.<br />

37. The Select Committee also noted the lack of capital investment in drainage<br />

improvement as a possible area for recommendation.<br />

The Environment Agency<br />

38. On 31 March, Paul Lockhart, Area Flood Risk Manager for the Environment<br />

Agency briefed the select committee on the Environment Agency’s capital<br />

schemes – the Nottingham Left (North) Bank Flood Alleviation Scheme; this<br />

proposed scheme will protect over 16,000 properties from Sawley near the<br />

M1 to Radcliffe Viaduct at Colwick. Additionally, the £14.7m West Bridgford<br />

scheme, to be largely completed in the summer of 2007, will protect 5600<br />

homes.<br />

39. Mr Lockhart recognised that there was no flooding from the Trent itself<br />

during the summer 2007 foods. The Environment Agency has responsibility<br />

for flooding from “main rivers” and in <strong>Nottinghamshire</strong> these include: the<br />

Soar, Idle, Trent and Derwent. Other than the Environment Agency, there is<br />

no single body with a strategic overview thus leaving the EA best placed to<br />

engage in a “holistic” approach to managing flooding.<br />

10


40. The Environment Agency works closely with Severn Trent Water and<br />

welcomes the appointment of Andy Wallace at NCC as <strong>Drainage</strong> Manager.<br />

41. Due to the severe flooding in Lowdham, the Environment Agency has<br />

commissioned consultants to carry out a review of the Lowdham Flood<br />

Alleviation Scheme and suggest options for improvement (the results of<br />

which are due shortly). A working party has been set up to work through the<br />

issues and keep the local community informed.<br />

42. The Environment Agency has also carried out extensive de-silting<br />

throughout Lowdham in conjunction with the Newark Area Internal <strong>Drainage</strong><br />

Board.<br />

43. In Woodborough, the Environment Agency has commissioned consultants to<br />

carry out a review and recommend options for improvement while also<br />

removing nearly 100 tonnes of silt from culverts through the village.<br />

44. Further to last summer’s floods, other Environment Agency projects include<br />

a feasibility study on the assessment of river channels and culverts in<br />

Worksop, surveying and cleaning of becks in Retford and the modelling of<br />

the River Greet (including the Potwell Dyke) in Southwell and Rolleston.<br />

Severn Trent<br />

45. Also on 31 March, Margaret Burrup of Severn Trent Water, gave a<br />

presentation on the company’s role. She stated that many private drains<br />

were unadopted, and had never been raised to an adoptable standard.<br />

Public sewers in June/July 2007 had been overwhelmed by the rainfall,<br />

compounded by underlying problems affecting capacity, such as fat deposits<br />

and debris. The public were able to report drainage problems on the<br />

company’s 0800 telephone number. The drains were only designed to cope<br />

with a one in 40 year storm.<br />

46. In relation to home insurance, Severn Trent’s advice to householders is not<br />

to neglect cover for fire and theft even if cover for flooding is not available<br />

to them.<br />

47. The Select Committee noted that ultimately surface water and foul water<br />

drainage systems combined; which meant that surface water was put<br />

through expensive sewage treatment systems and that planning authorities<br />

could ameliorate this by insisting on sustainable urban drainage systems for<br />

new developments.<br />

48. The Select Committee also noted the reluctance on the part of both the<br />

Environment Agency and Severn Trent to engage in expensive litigation and<br />

the tendency to favour negotiated settlement rather than enforcement.<br />

Newark Area Internal <strong>Drainage</strong> Board<br />

49. On 28 April, Steve Broadhead, Chief Engineer with the Newark Area Internal<br />

<strong>Drainage</strong> Board briefed the Select Committee on the work of his<br />

organisation. Mr Broadhead has spent the last 30 years – his whole working<br />

life – with the Newark Area Internal <strong>Drainage</strong> Board. Internal <strong>Drainage</strong><br />

Boards (IDBs) are statutory authorities set up since 1936 to provide<br />

drainage in low lying areas. NAIDB covers <strong>Nottinghamshire</strong> and also parts of<br />

11


Leicestershire and Lincolnshire across eight districts and covering 555<br />

square kilometres. IDBs cover contour based areas defined as eight feet<br />

above highest known flood levels. Their function is to maintain natural open<br />

watercourses – NAIDB maintains 600 kilometres of watercourses. It is<br />

managed by a board of elected members (and local councillors) and meets<br />

four times a year.<br />

50. Funding of the board is through a drainage rate on agricultural land.<br />

£500,000 is also contributed by Newark and Sherwood District <strong>Council</strong>.<br />

Newark and Sherwood were badly affected by the summer floods –<br />

especially west of the Trent (e.g. Southwell & Lowdham). NAIDB employees<br />

assisted where they could but were not in a position to supply sandbags.<br />

The Board had recently completed 6-9 months weed cutting on watercourses<br />

associated with flooding.<br />

51. Mr Broadhead stated that under the Land <strong>Drainage</strong> Act, farmers and other<br />

landowners could be compelled to clear watercourses. However, NAIDB has<br />

never taken legal action against anyone for failure to maintain a<br />

watercourse; matters have been resolved by agreement. In the 1970’s<br />

grants were paid by the Ministry of Agriculture Fisheries and Food to assist<br />

in the clearance of watercourses.<br />

Representation from Parish <strong>Council</strong>s<br />

52. The Select Committee wrote to Parish <strong>Council</strong>s in Bassetlaw, Gedling and<br />

Newark and Sherwood inviting submission of information on the response to<br />

the summer floods (e.g. what went well, where improvements could be<br />

made, and whether or not there was effective partnership working). These<br />

responses are summarised in Appendix A. In addition, a number of Parish<br />

<strong>Council</strong>s affected by the summer floods made representation to the Select<br />

Committee on 28 April. The following points were raised:<br />

53. Balderton Parish <strong>Council</strong> (<strong>Council</strong>lor Angela Jarvis and Mr Bernard Gascoine)<br />

• The backwash of sewage experienced at Staple Lane<br />

• Blockage of a watercourse with a fencepost<br />

• The small size of drains – only nine inches in diameter<br />

• Complex and long-standing issues around the culvert under Warwick<br />

Road<br />

54. North Leverton with Habblesthorpe (Mr Colin Walker) – a quarter of North<br />

Leverton was flooded – the residents are grateful for the reinstatement of<br />

roads and the swift response of John McGuigan from the Emergency<br />

Planning Department. The level of consultation from <strong>Nottinghamshire</strong><br />

<strong>County</strong> <strong>Council</strong> was good but concerns remained about the length of time<br />

taken to re-open the local primary school that was closed by the flooding<br />

(not due to re-open until December 2008).<br />

55. Mr Walker explained that North Leverton came under Laneham Internal<br />

<strong>Drainage</strong> Board – which is operated independently by consultants based in<br />

Doncaster - and had suffered worsened flooding as a result of the inundation<br />

of a pump located at the West Burton Power Station. On a point of<br />

clarification, Mr Broadhead of Newark Area Internal <strong>Drainage</strong> Board (NAIDB)<br />

added that since pumps could be subject to failure and power loss some<br />

12


drainage boards had tractor driven back-ups, but this was dependent on<br />

risk. NAIDB did not suffer flooding as a result of loss of power.<br />

56. Walkeringham (Mr Peter Roberts) – Mr Roberts stated that some people<br />

were still out of their homes, but that the response from Emergency<br />

Planning had been good. However, the Highways Department has “sloping<br />

shoulders” when it comes to taking responsibility for watercourses which<br />

abut the highway.<br />

57. The Select Committee noted the need to more widely educate members of<br />

the public about the responsibilities relating to dykes adjoining the highway<br />

– these are the responsibility of the landowner rather than the highways<br />

department.<br />

58. Southwell (<strong>Council</strong>lor Beryl Prentice)<br />

• The last residents returned to their homes only three weeks ago<br />

• A modelling exercise will take place on the Potwell Dyke<br />

• The <strong>County</strong> <strong>Council</strong> is redrawing the boundaries around the new Minster<br />

School and thereby taking on riparian ownership responsibilities for the<br />

Potwell Dyke<br />

• Emergency Plan is not quite finished but John McGuigan has been very<br />

helpful<br />

• Newark and Sherwood District <strong>Council</strong> will provide a sandbag store<br />

shortly<br />

59. Burton Joyce (Mrs Julie O’Neil)<br />

• Unprecedented rain resulted in blockages to culverts; the system was<br />

unable to cope<br />

• A large number of outbuildings flooded – this included flooding with<br />

sewage<br />

• More needs to be done to inform landowners of their responsibilities<br />

• Produced an informative leaflet for residents with contact details of<br />

agencies<br />

• The response from local authorities is disappointing and there is a lack of<br />

co-ordination<br />

60. Woodborough (<strong>Council</strong>lor Margaret Briggs)<br />

• The Environment Agency has removed 50 tons of debris from the Beck<br />

• <strong>Nottinghamshire</strong> <strong>County</strong> <strong>Council</strong> has utilised CCTV in drains and culverts<br />

to identify problems<br />

• A survey is taking place on the feasibility of major flood defence works<br />

61. Lowdham (<strong>Council</strong>lor David Harper and Mr Martin Shaw)<br />

• Flooded five times last summer<br />

• The Cocker Beck is currently subject to modelling by the Environment<br />

Agency and Severn Trent<br />

• The emergency services appeared to suffer from a lack of co-ordination<br />

and would have benefited from consulting people with local knowledge<br />

• The emergency services “Gold Command” should liaise with the Parish<br />

<strong>Council</strong><br />

13


• Sandbags only had limited effect<br />

• There were problems associated with the capacity of the Merevale Bridge<br />

• A large pump brought from Ashfield could not be used [because there<br />

was nowhere to pump the water]<br />

Lowdham Village Site Visit<br />

62. On 6 th May the Select Committee undertook a site visit to Lowdham<br />

accompanied by Andy Wallace, <strong>Drainage</strong> Manager, NCC, John McGuigan,<br />

Emergency Planning Manager, NCC, Dave Bartram, Environment Agency,<br />

<strong>Council</strong>lor David Harper and Mr Martin Shaw of Lowdham Parish <strong>Council</strong>.<br />

63. Members of the Select Committee saw the Cocker Beck – a fairly substantial<br />

watercourse – and heard how the Environment Agency had cleared much of<br />

the overgrowth of plants and weeds from its banks after the flooding events<br />

last summer.<br />

64. Walking along a footpath on the bank of the Cocker Beck, Members were<br />

told that the plastic piles deployed like an underground wall were not<br />

effective and a one metre wall was now planned by the Environment Agency<br />

to protect properties.<br />

65. On the lower part of Main Street there is a bridge over the watercourse with<br />

a low parapet which may exacerbate flooding. This bridge is owned by the<br />

<strong>County</strong> <strong>Council</strong>. However, improvement works to the bridge would be<br />

problematic since it is the only access point for the forty or so houses in the<br />

development beyond.<br />

66. At the Lime Tree Gardens Bridge, Members of the Select Committee saw<br />

where the old channel had been partially closed off and a new channel built.<br />

The remnants of the old channel caused problems resulting in unnecessary<br />

erosion to the far bank.<br />

67. In the Blenheim Avenue Estate Members of the Select Committee saw the<br />

Highways Pumping Station and heard how the locks on its access hatches<br />

had been removed and replaced by the Fire and Rescue Service while taking<br />

necessary action during the course of the flood. Unfortunately, the new lock<br />

keys were passed to Severn Trent instead of NCC and this did result in an<br />

access problem. Subsequently, the Fire and Rescue Service have been<br />

informed that the pumping station is a county council asset. In addition, it<br />

was apparent that locating an unfenced pumping station in a housing<br />

development had potential health and safety implications e.g. for trips and<br />

falls/danger to children playing on it. Select Committee Members were also<br />

concerned that some residents might consider the pumping station an<br />

eyesore.<br />

North Leverton with Habblesthorpe Visit<br />

68. On 19 th May, Members of the Select Committee visited North Leverton with<br />

Habblesthorpe – site of some of the most severe flooding in <strong>Nottinghamshire</strong><br />

last summer.<br />

69. The Select Committee saw firsthand the complexities of the watercourses in<br />

North Leverton. With the watercourse running along the gardens of domestic<br />

14


properties there were many dozens of riparian owners involved. In some<br />

places the watercourse was narrowed by the construction of ornamental<br />

stonework features (or even the installation of substantial pre-fabricated<br />

concrete walls); in others utility cables crossing the watercourse caused a<br />

restriction to the flow of water.<br />

70. Another issue was sudden changes in the angle of the watercourse; in some<br />

instances floodwater had “hit a bend but carried straight on.”<br />

71. The Select Committee were also shown where the road surface was scoured<br />

away by the force of the floodwater emerging from a public footpath. The<br />

road surface has subsequently been reinstated by the Highways<br />

Department.<br />

72. The Select Committee also saw the catchwater drain, on the outskirts of the<br />

village. A severe overgrowth of vegetation on its banks that had exacerbated<br />

the flooding had now been cut back by Laneham Internal <strong>Drainage</strong> Board.<br />

73. The Select Committee noted that in the case of both villages that it was<br />

necessary to make a site visit in order to fully understand the scale and<br />

severity of the floods and their effect on residents.<br />

Summary of Findings<br />

74. The frequency of gully emptying has been reduced by local authorities as an<br />

economy measure. Since a free flowing drainage system is essential during<br />

instances of sustained rainfall to prevent flash flooding this may to some<br />

extent be a false economy. There perhaps needs to be an acceptance that<br />

money spent on preventing the misery of flash flooding is money well spent<br />

– this is particularly important since development (and the construction of<br />

patios and non-permeable hard standing driveways) has substantially<br />

reduced natural soak-away and thereby increased the burden on the<br />

drainage system.<br />

75. To be effective, an increased programme of gully emptying would require<br />

targeted communication with local residents where works are to be carried<br />

out to prevent them from parking over highway drain covers when cleansing<br />

vehicle operators require access.<br />

76. The Newark Internal <strong>Drainage</strong> Board informed the Select Committee that it<br />

had never pursued a riparian owner who had not fulfilled their<br />

responsibilities through the courts. While the Select Committee has no wish<br />

to see organisations unnecessarily mired in expensive litigation, and it is<br />

obviously commendable that the vast majority of problems can be resolved<br />

through negotiation; <strong>Drainage</strong> Boards and other responsible authorities<br />

should not hesitate to bring the full force of the law against recalcitrant<br />

riparian owners.<br />

77. The responsibility to mitigate the effects of flooding lies both with all of us<br />

individuals and with relevant agencies – for instance we all have a<br />

responsibility not to irresponsibly dispose of cooking fat down our domestic<br />

drains since it can accumulate and even block very substantial drains –<br />

likewise, agencies with a responsibility to manage the effects of flooding<br />

should robustly defend their assets against the “worst case scenario.” An<br />

15


example of this is the pumping station at West Burton Power Station which<br />

was inundated and resulted in worsened flooding in the North Leverton area.<br />

78. Homeowners at risk have a personal responsibility to improve the resilience<br />

of their properties through the installation of self-closing airbricks and<br />

floodgates. The Select Committee hopes that all insurance companies have<br />

the good sense not to penalise homeowners for taking preventative action.<br />

79. At present there seems to be an over-reliance on sandbags and unrealistic<br />

expectations of their effectiveness and a feeling that local authorities should<br />

deliver them to anyone who thinks that they might benefit from them.<br />

80. The transportation of sandbags into areas that have flooded or are in the<br />

process of flooding is problematic. As a matter of commonsense, areas that<br />

are likely to benefit from provision of sandbags should have a local store –<br />

as near as possible to where they will be deployed. This would make<br />

residents aware of the finite provision and would circumvent the need to<br />

make logistical arrangements. It would be ironic indeed if the transportation<br />

of sandbags by heavy goods vehicles caused bow waves which worsened the<br />

flooding for some residents.<br />

81. When flood warden schemes are being set up, existing community groups,<br />

such as Neighbourhood Watch, may prove a valuable source of volunteers<br />

and should perhaps be contacted in the first instance.<br />

82. In the absence of a single over-arching authority responsible for all flooding<br />

issues, people likely to be affected by flooding have a right to know which<br />

services they can expect to receive from which agency or local authority.<br />

Responsibilities and contact details should be clearly presented in a leaflet or<br />

booklet to be made available to residents and businesses.<br />

83. There is an obvious requirement for a central record of riparian ownership<br />

and responsibility. This Authority should ensure that where records exist<br />

they are collated and where they do not exist they are created following<br />

careful research. Ultimately, it might be useful if the final product of this<br />

mapping exercise is made available on-line (as Newark Internal <strong>Drainage</strong><br />

Board’s maps are at present). Further, the identification of riparian owners<br />

would allow them to be reminded of their responsibilities in a targeted or<br />

prioritised way; especially those who may be obstructing the flow of water<br />

by serious neglect or unthinking and inappropriate development.<br />

84. Some areas of England, such as Gloucestershire, suffered much more than<br />

<strong>Nottinghamshire</strong> during last summer’s floods. This would seem to beg the<br />

following questions: What if <strong>Nottinghamshire</strong> had been at the centre of the<br />

flooding event? What would have been the effect on the critical<br />

infrastructure of the county? The future may not bring a precise recurrence<br />

of the 2007 floods. It may bring other more extreme weather events. It is<br />

not hard to imagine, for example, a severe winter storm which floods the<br />

M1, or other major roads, stranding thousands of motorists; or a coastal<br />

storm surge causing catastrophic flooding in Lincolnshire which results in<br />

requests for assistance to this Authority. Weak points in the critical<br />

infrastructure which could affect <strong>Nottinghamshire</strong> – especially in terms of<br />

transport and utilities - are worth carefully identifying and it would be useful<br />

for the emergency planning team to ensure that they are aware of them and<br />

16


develop appropriate responses. Weaknesses which fall outside the county’s<br />

geographical boundary but affect the county should also be considered.<br />

85. Ensuring that the critical infrastructure is robustly defended is worthy of<br />

further scrutiny. It is perhaps an issue that Overview and Scrutiny could<br />

commission a topic select committee to look at, when the work programme<br />

allows.<br />

86. The Select Committee welcomes interim conclusion 26 of Sir Michael Pitt’s<br />

report (page 54) which suggests that local authority scrutiny committees<br />

should review Surface Water Management Plans, and other linked plans,<br />

such as Local Development Frameworks and Community Risk Registers. An<br />

ongoing role for Scrutiny around flooding issues would be valuable. While<br />

this report was being finalised Sir Michael Pitt published his final report and<br />

recommendations. The recommendations are attached as Appendix B.<br />

17


Recommendations<br />

<strong>Drainage</strong><br />

1<br />

Highways gullies are emptied more frequently. Preferably, a spring and<br />

autumn clean of gullies should take place.<br />

2<br />

Residents should be notified in good time when gully cleansing is due to<br />

take place so that they can avoid parking over gully drainage grates<br />

3<br />

Within the Authority’s budgetary constraints, the funding and<br />

development of a capital programme of prioritised highway drainage<br />

improvements should be considered<br />

<strong>Watercourses</strong> and Internal <strong>Drainage</strong> Boards<br />

4<br />

Internal <strong>Drainage</strong> Boards should more vigorously pursue, through the<br />

legal remedies that are open to them, riparian owners who do not<br />

properly fulfil their obligations<br />

5<br />

Internal <strong>Drainage</strong> Boards should ensure that they robustly defend their<br />

critical assets from flooding (e.g. pumps) and invest in back-up<br />

measures wherever it is viable to do so<br />

Residents/this Authority/other authorities<br />

6<br />

In association with relevant partners, this Authority should raise<br />

awareness about the severe problems that can be caused by disposing<br />

of cooking fat down drains<br />

7<br />

This Authority should deploy temporary road signs in the approach to<br />

flooded areas warning of the severe “bow wave” effects that can result<br />

from large vehicles driving into floodwater at speed<br />

8<br />

The owners of properties that are susceptible to flooding should put in<br />

place measures to improve the resilience of their property (e.g.<br />

floodgates and self closing airbricks) rather than rely on the delivery of<br />

sandbags<br />

9<br />

Parish and District <strong>Council</strong>s should consider the strategic storage of<br />

sand bags, silicon granule bags or other alternatives as close as<br />

possible to where they are likely to be required<br />

18


10<br />

Local Authorities (and other organisations) should recognise that<br />

existing community groups (e.g. Neighbourhood Watch) may provide a<br />

valuable resource or pool of potential volunteers for flood warden-type<br />

schemes<br />

11<br />

This Authority in association with District Authorities, the Environment<br />

Agency, Severn Trent and the Internal <strong>Drainage</strong> Boards should produce<br />

a publication clearly setting out contact details and areas of<br />

responsibility relating to flooding and what support flooded<br />

homeowners can expect<br />

12<br />

The preparation of emergency plans by Parish <strong>Council</strong>s be recognised<br />

as good practice; and therefore parishes who have not done so should<br />

consider producing a plan and circulating it to relevant agencies and<br />

authorities<br />

Emergency Services<br />

13<br />

The Police and Fire and Rescue Services should liaise more closely with<br />

residents who have in-depth local knowledge (e.g. representatives of<br />

the Parish <strong>Council</strong>)<br />

Riparian Owners<br />

14<br />

This Authority co-ordinate a thorough mapping of riparian ownership<br />

within the <strong>County</strong>; collating information held by other organisations,<br />

such as Districts and Parishes and commissioning research to fill gaps<br />

in knowledge with a view to producing a definitive document that is<br />

kept up to date<br />

15<br />

Further to this mapping exercise, all riparian owners should be<br />

reminded of their responsibilities – and, as a priority riparian owners<br />

who have built structures that encroach into watercourses should be<br />

specifically approached and informed of the potentially catastrophic<br />

effect of restricting the flow of water during flash floods<br />

Weak Points in the Critical Infrastructure<br />

16<br />

Emergency Planning Officers carefully consider where the weak points<br />

in <strong>Nottinghamshire</strong>’s critical infrastructure would be in the event that<br />

<strong>Nottinghamshire</strong> suffers the sort of massive pluvial flooding<br />

experienced by Gloucestershire last summer<br />

19


17<br />

The Overview and Scrutiny Committee should consider a further<br />

scrutiny review of this authority’s plans for civil contingencies,<br />

especially around weaknesses in the critical infrastructure which might<br />

lead to catastrophic long term failure of utilities and the transport<br />

network<br />

Pitt Review<br />

18<br />

Overview and Scrutiny Committee should receive a briefing on the<br />

implementation of the Pitt Review’s recommendations in nine months<br />

and following that determine what further scrutiny of flooding issues<br />

should be incorporated into the future work programme.<br />

20


APPENDIX A<br />

<strong>Flooding</strong> (drainage and watercourses)<br />

Parish <strong>Council</strong> Response<br />

27 affected Parish <strong>Council</strong>s in <strong>Nottinghamshire</strong> detailed their experiences of<br />

the 2007 floods – their main concerns, the things that went well, the things<br />

to be improved and the level of partnership working that took place.<br />

The main concern was with poor maintenance - to dykes, ditches, drains<br />

and culverts and the problems of contamination from raw sewage.<br />

Only Bleasby, Caunton and Weston Parish <strong>Council</strong>s considered that anything<br />

went well and that was the response, both before and after the flooding, of<br />

District and <strong>County</strong> <strong>Council</strong>s, the Environment Agency and the <strong>Drainage</strong><br />

Board.<br />

The Parish <strong>Council</strong>s would like to see a faster and better-coordinated<br />

response to the flooding with better co-ordination and communications<br />

between the emergency services and the different authorities. Clarity over<br />

ownership of dykes, culverts and drains - and who has responsibility for<br />

maintenance and repair - would also be a welcome improvement.<br />

Misterton Parish <strong>Council</strong> reported a ‘top class service’ from the <strong>County</strong><br />

<strong>Council</strong> and Caunton commended Newark & Sherwood District <strong>Council</strong> for<br />

an ‘excellent job’. However, Dunham on Trent considered the response of<br />

Severn Trent to have been too slow, while Rolleston Parishioners felt<br />

‘isolated and neglected’ and considered that effective partnership working<br />

had not taken place.<br />

<strong>Flooding</strong> occurred between 23 – 25 June. Questionnaire circulated to 100 residents. 36 responses received. Of these about half experienced<br />

flooding in their houses and of these, half had to move out.<br />

Culverts, bridges and driveways over<br />

the dykes seem to have limited the flow<br />

and diverted water up onto the roads.<br />

State of the surrounding field ditches<br />

contributed to surface water flooding.<br />

Pitt Review - Recommendations and<br />

progress - Appendix B<br />

RECOMMENDATION RESPONSIBILITY PROGRESS COMPLETION DATE COMMENTS<br />

Recommendation 1:<br />

Given the predicted increase in the range of future extremes of<br />

weather, the Government should give priority to both adaptation and<br />

mitigation in its programmes to help society cope with climate<br />

change.<br />

Recommendation 2:<br />

The Environment Agency should progressively take on a national<br />

overview of all flood risk, including surface water and groundwater<br />

flood risk, with immediate effect.<br />

Recommendation 3:<br />

The Met Office should continue to improve its forecasting and<br />

predicting methods to a level which meets the needs of emergency<br />

responders.<br />

Recommendation 4:<br />

The Environment Agency should further develop its tools and<br />

techniques for predicting and modelling river flooding, taking account<br />

of extreme and multiple events and depths and velocities of water.<br />

Recommendation 5:<br />

The Environment Agency should work with partners to urgently take<br />

forward work to develop tools and techniques to model surface water<br />

flooding.<br />

Recommendation 6:<br />

31


<strong>Flooding</strong>: <strong>Drainage</strong> & <strong>Watercourses</strong><br />

The Environment Agency and the Met Office should work together,<br />

through a joint centre, to improve their technical capability to forecast,<br />

model and warn against all sources of flooding.<br />

Recommendation 7:<br />

There should be a presumption against building in high flood risk<br />

areas, in accordance with PPS25, including giving consideration to all<br />

sources of flood risk, and ensuring that developers make a full<br />

contribution to the costs both of building and maintaining any<br />

necessary defences.<br />

Recommendation 8:<br />

The operation and effectiveness of PPS25 and the Environment<br />

Agency’s powers to challenge development should be kept under<br />

review and strengthened if and when necessary.<br />

Recommendation 9:<br />

Householders should no longer be able to lay impermeable surfaces<br />

as of right on front gardens and the Government should consult on<br />

extending this to back gardens and business premises.<br />

Recommendation 10:<br />

The automatic right to connect surface water drainage of new<br />

developments to the sewerage system should be removed.<br />

Recommendation 11:<br />

Building Regulations should be revised to ensure that all new or<br />

refurbished buildings in high flood-risk areas are flood-resistant or<br />

resilient.<br />

Recommendation 12:<br />

All local authorities should extend eligibility for home improvement<br />

grants and loans to include flood resistance and resilience products<br />

for properties in high flood-risk areas.<br />

32


<strong>Flooding</strong>: <strong>Drainage</strong> & <strong>Watercourses</strong><br />

Recommendation 13:<br />

Local authorities, in discharging their responsibilities under the Civil<br />

Contingencies Act 2004 to promote business continuity, should<br />

encourage the take-up of property flood resistance and resilience by<br />

businesses.<br />

Recommendation 14:<br />

Local authorities should lead on the management of local flood risk,<br />

with the support of the relevant organisations.<br />

Recommendation 15:<br />

Local authorities should positively tackle local problems of flooding by<br />

working with all relevant parties, establishing ownership and legal<br />

responsibility.<br />

Recommendation 16:<br />

Local authorities should collate and map the main flood risk<br />

management and drainage assets (over and underground), including<br />

a record of their ownership and condition.<br />

Recommendation 17:<br />

All relevant organisations should have a duty to share information<br />

and cooperate with local authorities and the Environment Agency to<br />

facilitate the management of flood risk.<br />

Recommendation 18:<br />

Local Surface Water Management Plans, as set out under PPS25<br />

and coordinated by local authorities, should provide the basis for<br />

managing all local flood risk.<br />

Recommendation 19:<br />

Local authorities should assess and, if appropriate, enhance their<br />

technical capabilities to deliver a wide range of responsibilities in<br />

relation to local flood risk management.<br />

33


<strong>Flooding</strong>: <strong>Drainage</strong> & <strong>Watercourses</strong><br />

Recommendation 20:<br />

The Government should resolve the issue of which organisations<br />

should be responsible for the ownership and maintenance of<br />

sustainable drainage systems.<br />

Recommendation 21:<br />

Defra should work with Ofwat and the water industry to explore how<br />

appropriate risk-based standards for public sewerage systems can be<br />

achieved.<br />

Recommendation 22:<br />

As part of the forthcoming and subsequent water industry pricing<br />

reviews, Ofwat should give appropriate priority to proposals for<br />

investment in the existing sewerage network to deal with increasing<br />

flood risk.<br />

Recommendation 23:<br />

The Government should commit to a strategic long-term approach to<br />
