Page 5 2 FLOOD AND WATER MANAGEMENT SCRUTINY COMMITTEE 25 NOVEMBER 2019

23 ANNOUNCEMENTS BY THE CHAIRMAN, EXECUTIVE COUNCILLORS AND LEAD OFFICERS

The Chairman reflected on the recent periods of extreme rainfall, emphasising that the extreme weather conditions were no longer exceptional, but the result of a shifting environmental climate. It was felt that the scrutiny had a role to play in shifting environments.

The Executive Councillor for Economy and Place concurred with the Chairman, advising that the rainfall patterns were much more intense and extreme weather was a regular occurrence.

It was noted that successive rainfall had added to high water levels and that systems were struggling to recover quickly enough, leaving the County more susceptible to further flooding. As a consequence, the Council's resources were under pressure.

Members were advised that Norfolk County Council were making good progress with the report on the Wainfleet flooding incident, with a large amount of data having already been gathered and it was currently being analysed. The full report was expected to be published at the start of 2020.

Members recognised the need for a greater investment from the Government to allow the Council to meet the challenges posed by climate change.

The Committee highlighted that importance of protecting Lincoln's agriculture, as it was a large food resource for the country and played a large part in Lincolnshire's economy. Members felt that Lincolnshire's agricultural land was being undervalued.

It was recognised that the Council needed to work with partners to examine the possibility to deliver long term solutions to flooding across the County, particularly in the rise of extreme weather and climate change.

The Executive Councillor for Commercial and Environmental Management emphasised that all risk management authorities in Lincolnshire had performed exceptionally well to ensure that events were being controlled the best that they could be.

The Executive Councillor for Commercial and Environmental Management raised concerns over the number of new houses being built on high flood risk areas and the approval of planning applications on this basis.

24 TO REPORT PROGRESS ON THE INVESTIGATIONS MADE IN THE COUNTY UNDER SECTION 19 OF THE FLOOD & WATER MANAGEMENT ACT 2010 (FWMA)

Consideration was given to a report by the County Flood Risk Manager, which invited the Committee consider the position of all current Section 19 (S.19) flood investigations in the County.

Page 6 3 FLOOD AND WATER MANAGEMENT SCRUTINY COMMITTEE 25 NOVEMBER 2019

Members were advised that there had been 40 further flood investigations initiated since the last report to the committee.

Members were informed that the long-term average rainfall in Lincolnshire over the last six months had been 'exceptionally high' in the central and southern parts of the county, and above normal in the most northern areas. Members were provided with an illustration of the rainfall totals in a number of catchments across the County.

The committee were reminded that Norfolk County Council were currently undertaking the investigation into the Wainfleet Flooding Incident on behalf of the Lincolnshire County Council (LCC). The investigation was progressing well and it was hoped that the report would be completed by early 2020.

Members were referred to Appendix A to the report, which detailed the record of current flood investigations in the County carried out in accordance with Section 19 of the FWMA. It was noted that there were currently 140 on-going investigations, which explicitly excluded sewer flooding. Lincolnshire County Council worked with partners where surface water had influenced sewage flooding, but these incidents were not included within the Section 19 investigations.

Members were invited to ask questions, in which the following points were noted:

 As a result of the growing number of flooding incidents, officer and budgetary resources were limited. Officers advised that the Council had a statutory duty under Section 19 of the FWMA to investigate flooding incidents caused by surface water. Provision was being made to ensure that officers had sufficient resource and budget to adequately investigate these issues.  It was clarified that completed investigations were not able to be removed from the log if work was still outstanding on these issues. Although LCC worked in partnership with other organisations to help resolve issues as quickly as possible, they did not have the power as the local flood authority to compel or instruct another organisation to carry out works. However, officers met regularly with partners to align programmes and look at solutions to outstanding issues.  Officers confirmed that the Council operated a 24 hour flood support line; however members of the public were advised to ring 999 if they were having serious flooding issues.  All contact with LCC was recorded and passed on to the local highways team or out of duty emergency officers. LCC then worked with partners to resolve flooding issues.  Members raised concerns over the number of on-going sewage water flooding incidents that had not been responded to. The Chairman agreed to write to Anglian Water to raise the Committee's concerns.  The Chairman agreed to write to the Executive Director - Place on behalf of the committee to request clarification on who the main point of contact should be for any anybody reporting a flooding incident. Members emphasised the importance of communicating a clear message to the public and having one clear point of contact in the event of a flooding issue.

Page 7 4 FLOOD AND WATER MANAGEMENT SCRUTINY COMMITTEE 25 NOVEMBER 2019

 It was clarified that for incident where life and properties were at serious risk, the Duty Strategic Commander would make a judgement to invoke an emergency situation, which would result in a combined response system being put in place.  Officers were recommending the use of Flood Sacks as an alternative replacement to sandbags. Flood sacks expanded to absorb water but were easier to dispose of.  Members questioned the point at which the spillage of sewage water became a public health issue. Officers agreed to investigate this and provide this information to Members following the meeting.  Members queried why the work status for the 2012 flooding incident in remained as 'on-going' when it appeared that LCC had been proactive in responding to the incident in 2012. Officers reiterated that they did not have the power to compel an organisation to complete works.  The committee agreed that going forward, a section be added to the S19 report to specify when LCC had carried out necessary works on outstanding S19's and had issued recommendations to external partners. It was requested that a description of outstanding work also be included.  The committee resolved that tighter reporting be sought in relation to outstanding S19's and the organisations responsible for outstanding works.  Members thanked the County Flood Risk Manager and all other officers for their hard work during challenging times.

RESOLVED:

1. That the report be noted; 2. That tighter reporting be sought in relation to outstanding S19's and the organisations responsible for outstanding works.

25 ENVIRONMENT AGENCY UPDATE

Consideration was given to a report by the Area Manager – Environment Agency, which provided an update on Environment Agency (EA) activities, including progress on key capital schemes.

The Area Manager – Environment Agency thanked those who had assisted with recent flooding issues within Lincolnshire. It was noted that work was still on-going to resolve some issues.

Partners across the county had worked extremely well together to manager risks throughout the county. Efforts were now focussed on the recovery of flooding incidents. The Environment Agency were currently operating a 24/7 emergency response rota and were in a period of heightened response, which was likely to continue to the end of 2019

The Environment Agency were currently dealing with flooding issues in 19 areas across Lincolnshire in four key locations. A team of inspectors were also ready to inspect the rest of the county.

Page 8 5 FLOOD AND WATER MANAGEMENT SCRUTINY COMMITTEE 25 NOVEMBER 2019

It was noted that the recent period of heavy rainfall had meant that Lincolnshire's riverbanks were under significant pressure. Officers were working closely with Internal Drainage Board colleagues to identify where issues had occurred.

Going forward, the Environment Agency would be analysing ways to make space for water and alleviate pressure on the farming community. Officers were investigating how to drive maintenance programmes in rural environments.

Members were invited to ask questions, in which the following points were noted:

 The Area Manager – Environment Agency agreed to provide Members with current recovery lists, timescales and completed maps of locations where the Environment Agency have carried out work on flooding issues.  It was confirmed that at the time of the meeting, there were eight properties within Lincolnshire with fluvial flooding issues, and 86 with surface water flooding.  Members were encouraged by the recovery efforts made by the Environment Agency. The Environment Agency agreed to provide an update on recovery.  It was noted that the Environment Agency were hoping to mobilise the breach on the river on the week commencing 25 November 2019.  It was confirmed that flood mapping was updated and reviewed every two to three years. A review was on-going to analyse the current climate and weather trends and amend the chance predictions where necessary.  Members raised concerns over flood map predictions in the area of Wilsford, as residents were struggling to obtain home insurance despite the area not having suffered from flooding in recent times. Officers advised that flood maps were based on predictions of extreme weather of 1 in 1000 rainfall. However, the Senior Flood Risk Manager - Environment Agency recognised that some maps may not be completely accurate for some locations and work was on- going to update them. The flood maps for the area of Wilsford would be reviewed as part of on-going work.  It was noted that members of the public had not been informed of the reasons for the decommissioning of the pumps at the Black Sluice Pumping Stations and were unaware of the alternative arrangements that had been put in place that would be more beneficial. Members were advised that plans were in place to provide this communication in due course.  Members were concerned by reports from farmers that had been advised that they were not permitted to fill their reservoirs. The Area Director – Environment Agency agreed to liaise with the relevant Member to resolve these issues.  It was clarified that dredging was one of a number of flood risk solutions. In the places where it was proven to be successful, the Environment Agency carried out dredging. Members were advised that dredging was not a flood risk solution alone, and was actually unsuitable in some places. Flood professionals would put in place the most effective flood risk solutions with the money available. Currently, the Environment Agency were focussed on the integrity of Lincolnshire's raised banks.

Page 9 6 FLOOD AND WATER MANAGEMENT SCRUTINY COMMITTEE 25 NOVEMBER 2019

 Officers had investigated the possibility of operating the grand sluice navigation lock in reverse, however the benefits of doing so were not found to be substantial enough to warrant doing so.

RESOLVED:

That the report and comments made be noted.

26 JOINT LINCOLNSHIRE FLOOD RISK & WATER MANAGEMENT STRATEGY 2019-2050

Consideration was given to a report by the Senior Commissioning Officer – Flood Risk, which invited the committee to consider the Lincolnshire Flood Risk & Water Management Strategy 2019 -2050.

Members were advised that the updated strategy provided a more holistic approach, by combining the flood risk management activities of the Council and its partners with a strategic view of water supply and resource management, and a stronger emphasis on the additional economic benefits that it could deliver for Lincolnshire.

Members were invited to endorse the Joint Lincolnshire Flood Risk & Water Management Strategy 2019-2050.

The Senior Commissioning Officer – Flood Risk thanked all risk management authorities across the county for their efforts in contributing to the final version.

Members were referred to Appendix A to the Executive report, which set out the Joint Lincolnshire Flood Risk and Water Management Strategy 2019 - 2050.

Members were satisfied with the updated report agreed to endorse the strategy.

RESOLVED:

That strategy be endorsed by the Committee.

27 FLOOD AND WATER MANAGEMENT SCRUTINY COMMITTEE WORK PROGRAMME

Consideration was given to a report by the Scrutiny Officer, which enabled the Committee to consider and comment on the content of its work programme for the coming year to ensure that scrutiny activity was focussed where it could be of greatest benefit.

The Scrutiny Officer had noted the concerns raised by the Committee throughout the meeting and agreed to liaise with the Chairman and Vice-Chairman of the Committee to update the work programme where necessary.

Page 10 7 FLOOD AND WATER MANAGEMENT SCRUTINY COMMITTEE 25 NOVEMBER 2019

Policy and Scrutiny

Open Report on behalf of Andy Gutherson, Executive Director – Place

Report to: Flood and Water Management Scrutiny Committee Date: 24 February 2020 To report on the outcome of the investigation into the Subject: flooding at Wainfleet in June 2019 in accordance with S.19 Flood & Water Management Act 2010 KeyDecision decision? No Summary:Reference: Following a prolonged period of heavy rainfall in June 2019 there was widespread flooding across Lincolnshire. The eastern side of the county was particularly affected, especially Wainfleet, , Spalding and . Most notably, a significant number of properties in Wainfleet were flooded from a variety of sources, initially surface water compounded by a breach in the embanked Wainfleet Relief Channel.

Actions Required: The Flood and Water Management Scrutiny Committee are requested to:

a) Review the flood investigation report (Appendix A) and consider the outcomes and recommendations made therein; b) Endorse Lincolnshire County Council as Lead Local Flood Authority to lead on the partnership approach in delivering the recommendations as set out below and in Appendix A; c) Highlight any additional actions for consideration.

1. Background

Following a prolonged period of heavy rainfall in June 2019 there was widespread flooding across Lincolnshire. The eastern side of the county was particularly affected, especially Wainfleet (All Saints), Holbeach, Spalding and Great Steeping. Most notably, a significant number of properties in Wainfleet were flooded from at least two sources, initially surface water compounded by a breach in the embanked Wainfleet Relief Channel.

Over the period 10th to 13th June 2019 around 62 properties were flooded in Wainfleet, Thorpe St.Peter and Thorpe Culvert, with further significant flooding elsewhere in East Lindsey District which falls outside the scope of this Scrutiny Committee report.

Page 13 The consequences of the breach at Wainfleet were severe enough to trigger a multi- agency response in order that military aid could be called upon.

As Lead Local Flood Authority, Lincolnshire County Council has a duty under S.19 of the Flood & Water Management Act 2010 to investigate flooding as follows: (1) On becoming aware of a flood in its area, a lead local flood authority must, to the extent that it considers it necessary or appropriate, investigate— (a) which risk management authorities have relevant flood risk management functions, and (b) whether each of those risk management authorities has exercised, or is proposing to exercise, those functions in response to the flood. (2) Where an authority carries out an investigation under subsection (1) it must— (a) publish the results of its investigation, and (b) notify any relevant risk management authorities.

The events at Wainfleet (and elsewhere) met the requirement to carry out a flood investigation. Due to the increased pressure on resources as a result of the widespread flooding, Norfolk County Council were approached to carry out the flood investigation on behalf of Lincolnshire County Council in order to help it meet its duties under S.19 of the Flood &Water Management Act, which allows for one risk management authority to carry out flood risk management activities on behalf of another risk management authority.

Norfolk County Council were engaged to undertake the flood investigation to: i. Determine the cause(s) of the flooding, including limitations or failures, if any, in the current infrastructure etc.; ii. Determine which risk management authorities have relevant flood risk management functions; iii. Determine if any or each of those risk management authorities has exercised, or is proposing to exercise, those functions in response to the flood; and iv. Provide one or more possible strategic level options, if appropriate, to remove or reduce the risk of future flooding, or, if not appropriate, indicate the next steps that might be taken to identify and appraise the options.

The final report is attached at Appendix A.

2. Conclusion

The conclusions of the flood investigation report are that the most significant flooding was caused by the Relief Channel overtopping as a result of prolonged and heavy rainfall within the Steeping catchment, exacerbated by the bank eroding at the point of overtopping leading to a breach.

Before the breach occurred, there was surface water flooding affecting 14 properties as a result of the capacity of the surface water drainage systems being exceeded. The systems became surcharged, meaning water could not enter the systems, instead flowing over the surface.

Page 14 The investigation report concludes that the various risk management authorities identified as having a flood risk management function have exercised, or intend to exercise, their responsibilities in response to the flood.

In accordance with the requirements of S.19 Flood & Water Management Act, the results of the investigation will be published and the full investigation report made available on the County Council's website.

The various risk management authorities identified in the report as having a flood risk management function have been notified, as required by S.19 Flood & Water Management Act.

As required, Norfolk County Council have made a number of strategic level options, if appropriate, to remove or reduce the risk of future flooding, or, if not appropriate, indicate the next steps that might be taken to identify and appraise the options. For ease of reference these are summarised below together with some commentary on how the recommendation might be delivered; the full recommendations are in Appendix A.

1.1 Summary

The Steeping River is located in East Lincolnshire and drains almost 200km2 of the Wolds. The elevation of the area is only slightly above sea level with extensive areas of reclaimed peat and marshland. As a result, this region has a long history of flood risk. In the 1970s a flood relief channel was built to provide flood storage in the lower reaches of the Steeping River system, particularly during periods of tide lock.

On the 9th June 2019, the Met Office issued a yellow weather warning for . On the 11th June at 08:20 a flood alert was issued for the Steeping River. Flood Warning was issued at 23:36 on 11th June 2019 and Great Steeping Flood Warning was issued at 23:12 on 12th June 2019. Over the next few days 1000 people were evacuated from their homes, extensive overtopping culminated in a breach in the bank of the relief channel on 12th June. The Strategic Command Group declared an emergency incident.

The various pumping stations in the region were struggling to cope with the amount of water and on the 12th June Thorpe Culvert pumping station had to be turned off for one hour. On the 13th June, evacuation of the area commenced, a MACA (Military Aid to the Civil Authorities) request was sent to plug the breach in the relief channel and the first helicopter arrived on scene filling the breach by a third which consisted of 40 tonnes of material. By midnight on the 14th June, the breach had been sealed placing a total of 270 tonnes of material. On the 15th June more overtopping in the breach location led to a second military assistance request. A further 290 properties were evacuated as a precaution.

The affected properties were flooded from three sources: main river, ordinary watercourses and surface water. The area saw unusual levels of rainfall but, it is considered that the impact would have been significantly lessened had the breach not occurred. Although the relief channel has historically overtopped, the banks have not been known to breach before.

1.2 Flooding Incidents and Causes

This report has investigated the flood event that ensued and includes the internal flooding of 88 properties located across the East Lindsey District within the following parishes:

• Wainfleet All Saints (45); • , Thorpe Culvert& (18); • , Hundelby & Greetham (3); • Great Steeping (13); • Croft (6); • (3) Please note these properties fall outside of the Steeping catchment but have been included.

Across the area, 580 homes were evacuated over 6 days affecting around 1000 people.

The majority of properties affected were flooded by main river sources. The flooding that occurred led to the internal flooding of 61 properties.

A number of properties affected were flooded by surface water. The flooding that occurred led to the internal flooding of 14 properties.

3 Page 21 Of the remaining properties, 2 were flooded by ordinary watercourses, 9 by multiple sources and 2 properties are unknown.

Principal Causes:

The embankments alongside the relief channel, built after the flood event of 1968, are constructed from the arisings excavated in constructing the relief channel. They do not afford the protection of a newly constructed flood defence.

In March and May 2019, maintenance works were undertaken at the breach location. The work involved removing vegetation from the banks and filling in (with bare soil) rutting caused by cattle grazing and vehicle damage. However, the bank crest levels were not reduced during the operation and the grassed areas either side of the ruts were left untouched. It is standard practice for works of this nature to be undertaken at this time of year. However, it is worth noting that the majority of high rainfall events that we have information on also occurred during the summer months.

Significant rainfall fell across the catchment, particularly during the 10th and 11th of June which caused overtopping over an extended length of the bank. The breach formed as water flowed down the rear side of the bank and eroded away until insufficient support remained. The breach event exacerbated the impact and scale of the flooding.

Other Factors:

The relief channel splits the flow of the Steeping River, rather than acting as an overflow when river levels are high. The river system also contains a number of constrictions such as syphons and sluice gates and has periods of tide locking. This may slow the flow of the river and lead to increased siltation. The level of silt in the relief channel was a potential contributory factor in water levels reaching higher levels sooner.

Water levels in the Steeping River system, including the relief channel, are kept at a higher level during the summer months to allow for water abstraction.

Areas of river bank had been grazed by cattle which had caused some damage that was still evident on a site visit after the flood event (sheer banks in vicinity of breach). This may have weakened the bank, caused erosion and made it more susceptible to breaching.

The impact of the breach was compounded by the water flowing towards the railway line which acted as a conduit directing water across the wider catchment

Significant rainfall was directed into the surface water and foul drainage systems. This caused the network to surcharge. Flows that exceeded the system’s capacity contributed to the flooding.

Other Issues Raised:

Although evidence of badger activity was present in places along the relief channel, we have found no direct evidence of badger activity at the breach location.

4 Page 22 1.3 Recommendations

The recommendations made below have been assigned to the relevant Risk Management Authority (RMA). However, it is envisaged that the responsibility for reviewing, disseminating and implementing these recommendations will be shared collectively by the RMA’s; with Lincolnshire County Council, as Lead Local Flood Authority (LLFA), monitoring the implementation.

Lincolnshire County Council – Lead Local Flood Authority:

• Facilitate the review; dissemination and implementation of the findings and recommendations contained within this Section 19 investigation;

• Continue to improve partnership working between RMA’s through reviewing the current roles and responsibilities of Lincolnshire RMA’s; considering the 2019 flooding in Wainfleet and the updated Joint Lincolnshire Flood Risk and Drainage Management Strategy 2019-2050;

• Continue to work in partnership with landowners and the community to manage flood risk and promote best practice in relation to land management and property flood resilience;

• Develop an Emergency Plan for Wainfleet and the surrounding villages in conjunction with RMA’s, landowners, partner organisations and residents.

The Environment Agency:

• Assess the condition of existing raised embankments along the Steeping River and relief channel and consider the technical and financial feasibility of replacing these with new flood embankments. In doing so also consider the longer-term standard of protection and whether further mitigation measures are required;

• Continue to work in partnership with RMA’s to identify funding for flood mitigation measures and engage with residents, landowners and partner organisations to implement the measures identified;

• Monitor silt levels and vegetation growth in the Steeping River and relief channel and establish the benefits operational changes could provide, including: regular or one-off dredging of channels; reconfiguring the relief channel so that it is only is use during high flow events; and re-establishment and/ or reconfiguration of in channel sluices;

• Review maintenance regime for existing embankments along the Steeping River and the relief channel including the nature and timing of routine and future maintenance works and the risk should these coincide with periods of high-water levels;

• Continue to work in partnership with local landowners to improve land management practices in the Steeping River catchment, including: limiting the amount of sediment from adjacent farmland entering land drains and watercourses; controlling cattle access to river banks and provision of alternative drinking stations; and managing the effects of burrowing animals on the existing embankments.

5 Page 23 Internal Drainage Board (IDB):

• Continue to work in partnership with other RMA’s, residents, landowners and partner organisations to identify and implement flood mitigation measures and develop plans to manage flood risk;

6 Page 24 2 Justification for Flooding Investigation

Lincolnshire County Council (LCC) is a Lead Local Flood Authority (LLFA) as designated by the Flood and Water Management Act (FWMA) 2010 which places two duties upon them when flooding occurs:

FWMA 2010 section 19 – Local authorities: Investigations

1) On becoming aware of a flood in its area a lead local flood authority must, to the extent that it considers it necessary or appropriate, investigate:

a) Which risk management authorities have relevant flood risk management functions, and b) Whether each of those risk management authorities has exercised, or is proposing to exercise, those functions in response to the flood.

2) Where an authority carries out an investigation under subsection (1) it must: a) Publish the results of its investigation, and b) Notify the relevant risk management authorities.

In judging the impact or consequence of a flood event Lincolnshire County Council uses the criteria set out below;

• Any risk to loss of life; • Residential property: o One or more property flooded internally above ground floor level and/or below ground level where used as basement living accommodation; • Critical services/installations and vulnerable person's properties: o One or more property flooded internally above ground floor level and/or below ground level where used as basement living accommodation or of the provision of critical services; o One or more property rendered inoperable or their functions severely compromised due to the access to the premises being impassable; and/or resulting in a loss of service impacting on the local community; • Commercial property: o One or more property flooded internally above ground floor level and/or below ground level where used as basement operating space; • At least 2 hectares of agricultural land flooded for more than 2 days; • Any section of a national category 3 road or above made impassable due to flooding; and/or flooding to a minor road cutting off effective access to a village, hamlet or blocking a designated bus route; • Flooding adversely impacting normal timetables or cutting off of a rail link.

It was deemed necessary to complete a formal Investigation Report into the flooding in the catchment of the Steeping River as: • multiple residential properties were internally flooded; • critical services were rendered inoperable; • at least 2 hectares of agricultural land flooded for more than 2 days; • roads made impassable due to flooding; • flooding adversely impacting normal timetables.

7 Page 25 3 Scope of the Report

The LLFA, or another LLFA working on its behalf, will undertake whatever tasks and allocate appropriate resources as it deems reasonable and necessary to deliver the specific outputs within the agreed timescale.

To meet those requirements the LLFA will carry out an investigation to: i. Determine the cause(s) of the flooding, including limitations or failures, if any, in the current infrastructure, associated assets; ii. Determine which risk management authorities have relevant flood risk management functions; iii. Determine if any or each of those risk management authorities has exercised, or is proposing to exercise, those functions in response to the flood; iv. Provide one or more possible strategic level options, if appropriate, to remove or reduce the risk of future flooding, or, if not appropriate, indicate the next steps that might be taken to identify and appraise the options; v. Draft and submit a report in an agreed format.

The outputs will be: 1) A flood investigation report which meets the above (i to v) requirements, making recommendations with respect to iv.

3.1 Approach to completing the Flood Investigation Report

Norfolk County Council, working on behalf of Lincolnshire County Council, have spoken to all relevant Risk Management Authorities, Parish Councils and many local residents during site visits and following correspondence. A considerable amount of data was received during the investigation, that included historical data, probable causes and proposals for solutions and accounts of the event. A number of these accounts conflicted with each other.

However, we have not detailed all of the background information supplied as we have sought to keep this report concise and focussed on the key points of the event in June 2019 and the recommendations for future actions.

It is worth noting that the flood investigation report cannot: • Resolve the flooding issues • Provide designed or costed solutions; • Force authorities to undertake any of the recommended actions.

8 Page 26 4 The Steeping River Catchment

What are catchments? The purpose of viewing flooding incidents based on catchments reflects the reality that flooding does not respect the administrative boundaries of water management organisations. Hydrological catchments catch water and discharge it at locations known as outlets. Individual hydrological catchment boundaries are usually formed by ridges of surrounding higher ground, which separate the lower lying areas at a line known as a watershed.

Description of catchment: The Steeping catchment is predominately rural with small settlements and historic market towns such as and Wainfleet All Saints. The catchment encompasses the southern area of the Area of Outstanding Natural Beauty (AONB). Important chalk streams rise from the chalk outcrop in this catchment. To the south the catchment becomes coastal floodplain and the watercourses flow to the North Sea. There are protected areas in the catchment including important bathing waters, Natura 2000 sites and urban waste water directive sensitive sites.

Flood Risk within the catchment: The flood risk from strategic sources (fluvial above 3 square km and the sea) of flooding within this catchment has been assessed. The number of properties at risk are set out in Table 1 below for two different risk bandings, the 1 in 30 event (3.33% Annual Exceedance Event (AEP)) and the 1 in 100 event (1% AEP). This assessment does not take into account flood risk from groundwater or reservoir failure.

5 Risk Management Authorities' Responsibilities

Within the Steeping River Catchment, the following Risk Management Authorities (RMAs) have been identified: the Environment Agency (EA); the Lead Local Flood Authority (Lincolnshire County Council); Anglian Water Services (AWS); Highway Authority (LCC and Highways ); and the Witham Fourth District, Black Sluice and Lindsey Marsh Internal Drainage Boards (IDBs).

The Roles and Responsibilities of each of these RMAs are provided in Appendix A. Each of the above mentioned RMAs has exercised, or is proposing to exercise, those functions in response to the flood incident in Wainfleet in June 2019. The collective RMA response during the flood incident is summarised in Table 2.

9 Page 27 6 Flooding Incidents within the Catchment

Within this catchment 88 incidents of internal flooding have been assessed as part of this investigation. These incidents are detailed in the Table 2 below and mapped on Figure 2. Details of the response to incident are also provided in the right hand column of Table 2.

12 7 Recent Rainfall within the Catchment

This report seeks to draw on rainfall data to ascertain the intensity of the rainfall events experienced in the catchment that led to the flooding. This analysis is useful in assessing (in broad terms) if the design capacity of drainage systems within the affected areas was exceeded.

Firstly, historical data of previous rainfall events was examined. The 10th June 2019 ranked as the wettest June day as well as the wettest day in Wainfleet ever recorded. The average rainfall for the month of June in Wainfleet is 53.13mm. On the 10th June 2019, 74.6mm of rain was recorded falling in one day. This exceptional level is emphasised when compared to the last flood event in June 2007 which saw 42.6mm of rain fall in one day.

The 11th June 2019 ranked as the highest 24- hour rainfall period for Wainfleet on record with a total of 75.6mm.

In comparison to the county, the 10th June 2019 saw Wainfleet ranked third wettest June day in Lincolnshire. Holbeach and Cranwell (both within 30-40 miles of Wainfleet) saw rainfall that ranked them 7th and 8th wettest June day in Lincolnshire since records began.

To examine the rainfall that influenced the flooding in June 2019, data was collected from four rain gauges within the region for the week 10th – 18th June. The location of these rain gauges are highlighted in Figure 2 and a summary of the total rainfall that fell and the event rarity are provided in Table 3. It is worth noting that two of the rain gauges fall outside of the Steeping catchment.

The event rarity varied across the gauging stations. Wainfleet saw the most intense rainfall followed by Ulceby Cross.

Table 3: Rainfall Totals, Duration and Annual Exceedance Probability

Rain Gauge Within Depth of Duration Estimated Steeping Rainfall Annual Catchment Exceedance Probability

Wainfleet Yes 98mm 1.5 days 1.1%

Tetford Yes 94.8mm 1.5 days 2.3%

21 Page 39 Appendix A - Key definitions and responsibilities

What is flooding? Section 1 of the Flood and Water Management Act 2010 states that: “Flood” includes any case where land not normally covered by water becomes covered by water. In addition, this section adds the caveat: “But “flood” does not include – (a) a flood from any part of the sewerage system, unless wholly or partly caused by an increase in the volume of rainwater (including snow and other precipitation) entering or otherwise affecting the system, or (b) a flood caused by a burst water main (within the meaning given by Section 219 of the Water Industry Act 1991).”

What is internal and external flooding? For the purposes of this report, properties that have internally flooded are those where it is considered that water has entered the fabric of the building; • Basements and below ground level floors are included. • Garages are included if in the fabric of the building. Garages adjacent or separate from the main building are not included. • Occupied caravans are included but not tents.

External flooding included those properties where water has entered gardens or surrounding areas which restricts access, affects the highway or where flooding has disrupted essential services to the property such as sewerage. For businesses this includes those where the flood waters are directly preventing them trading as usual.

What is Local Flood Risk? Local Flood Risk is defined by the Flood and Water Management Act 2010 as being flood risk from surface runoff, groundwater and ordinary watercourses. • ‘Surface runoff’ means rainwater (including snow and other precipitation) which is on the surface of the ground (whether or not it is moving) and, has not entered a watercourse, drainage system or public sewer. • ‘Groundwater’ means all water which is below the surface of the ground and in direct contact with the ground or subsoil. • ‘Ordinary Watercourse’ means a watercourse that does not form part of a main river and includes a reference to a lake, pond or other area of water which flows into an ordinary watercourse.

Roles and Responsibilities of Risk Management Authorities: Below is a short summary of those groups and Risk Management Authorities ("RMAs") that have a role in managing flooding within Lincolnshire. The listing of responsibilities includes those duties or powers that directly relate to managing the flood incidents or consequence. All RMAs have a duty to cooperate with other RMAs.

Policy and Scrutiny

Open Report on behalf of Andy Gutherson, Executive Director – Place

Report to: Flood and Water Management Scrutiny Committee Date: 24 February 2020 To report progress on the investigations made in the Subject: County under Section 19 of the Flood & Water Management Act 2010 (FWMA) KeyDecision decision? Reference: No Summary: This is a standing item to inform the Committee of the position of all current S.19 flood investigations in the County.

Actions Required: Members of the Flood and Water Management Scrutiny Committee are invited to consider and comment on the investigations undertaken in the County under Section 19 of the Flood and Water Management Act 2010 (FWMA).

Members are asked to view the current S.19 spreadsheets online (also included at Appendix A) and inform Democratic Services in advance if they wish to highlight any particular sites at the forthcoming Scrutiny Committee meeting. https://www.lincolnshire.gov.uk/flood-risk-management/flood-investigations

1. Background

This is a standing item to inform the Committee on the position of all current Section 19 investigations in the County, which are listed in Appendix A. It will be noted that in some cases the investigation is marked as being completed, but the flood incident will remain on Appendix A as there may be outstanding works arising from recommendations in the investigation report which have not yet been completed or programmed by the relevant Risk Management Authority.

The following figures focus on the number of flood investigations started in Quarter 3 (October – December 2019). A total of 81 flood investigations were started in Quarter 3, 52 in November alone. According to the Environment Agency Water Situation Reports, the overall rainfall in Quarter 3 was generally 'Exceptionally High' in Lincolnshire, at between 173% and 200% of the long term average.

Page 43 Figure 1 illustrates the exceptional number of flood investigations undertaken in 2019 compared with the previous years, 2012 being the baseline figure which was when the County Council acquired the duty to investigate flooding.

Figure 1: Annual totals of flood investigations

Table 1 below provides a monthly breakdown of the number of flood investigations commenced in 2019 compared with 2018. This is by way of comparison only, such a short timescale cannot reliably be used to indicate a trend or pattern, although it does serve as a reminder of the unpredictability of flooding events.

Page 44 It should be noted that while investigations are underway it is not possible to give an indication of the local factors at play in each flood event. Even when some localities have experienced repeated flooding in a short period of time, until the investigation is completed it is not always possible to say which individual properties were victim to such flooding or if there are common causes between events. With an unprecedented number of flooding incidents members will understand that there is a consequent call on limited resources to carry out the investigations. Every effort is being made to complete the investigations in a timely manner, and the Committee will be pleased to learn that completed investigation reports into the flooding in 2019 are beginning to be received. The information published on the County Council web site will be updated accordingly.

With particular regard to the flooding in June at Wainfleet, the committee will be aware that Norfolk County Council is undertaking the investigation on behalf of Lincolnshire County Council. The investigation is now complete, details of which constitutes a separate paper to this meeting.

Members are invited to raise any questions about Appendix A or any other flooding queries with the Flood Risk Manager, whose contact details can be found at the end of this report.

Policy and Scrutiny

Open Report on behalf of the Environment Agency

Report to: Flood and Water Management Scrutiny Committee Date: 24 February 2020 Subject: Environment Agency Update KeyDecision decision? Reference: No Summary: To update the scrutiny committee on Environment Agency activities, primarily in relation to the Autumn flooding, response and recovery.

Actions Required: The Committee is invited to note the report.

1. Key Facts and Figures on Autumn Flooding

Figure 1, 2 and 3: UK rainfall compared to average, Sensitivity to rainfall and a news report highlighting the wet autumn compared to rainfall records

1.1 The images above show recent rainfall compared against average rainfall and the sensitivity of areas to rainfall. It can be seen that some areas in Lincolnshire saw 170% of its average rainfall during autumn 2019, with Lincolnshire being one of the worst hit areas in the country. The sensitivity to rainfall area map is a reflection of the amount of water in catchments and how sensitive Lincolnshire will be to any further rainfall.

Page 57

Figure 4. Lincolnshire and Northamptonshire rainfall chart 1.2 The above chart highlights the monthly rainfall within the Lincolnshire and Northamptonshire area. The June rainfall can clearly be seen as a spike, this was then followed by a further 7-8 months of consecutively higher than average rainfall.

1.3 There has only been 3 weeks within the last 7 months where the incident room was not open. The incident room was being opened for much lower levels of rainfall than previously, due to the saturation and responsiveness of catchments.

1.4 The Local Resilience Forum (LRF) only came into force at one acute stage, for the Barlings Eau breach.

1.5 Overall, in Lincolnshire, less than 1% of agricultural land flooded from main river sources and only 8 properties.

1.6 Three acute issues were seen; at Short Ferry and the Barlings Eau, Timberland Delph and Billinghay Skirth.

2. Recovery Updates

2.1 All affected main rivers were inspected and asset conditions recorded; as the catchments and raised river embankments dry out, we are undertaking further asset inspections.

2.2 There are currently more than 160 defects requiring repair and this number is still increasing.

2.3 22 priority sites for 2019-20 have been identified, including the works undertaken at Barlings Eau and Timberland Delph, described in further detail below.

2.4 We have been sharing targeted weekly updates with affected communities and also been reiterating landowners’ riparian roles, rights and responsibilities in managing flood risk.

2.5 The EA are allocated and spend public money on flood management activities in line with Government policy and treasury rules. Our priorities, as directed by Government, are on people and property.

3. Barlings Eau and Short Ferry

3.1 Work to repair the breach using 12m long steel sheet piles was completed on 20 December; pumping to dewater then commenced.

Page 58

3.2 On Friday 7th February, two additional Environment Agency 8 inch pumps were set up in the Witham 3rd IDB Stainfield Pumping Station compound. These are both now working to supplement the pumps set up on the opposite side of Short Ferry Road. Eventually one will be left with the IDB to provide temporary land drainage pumping at this site until the permanent pump is up and running again.

Figure 5 and 6: New pumps stationed at the Stainfield pumping compound 4. Timberland Delph

4.1 Work to reform the embankment has continued and the embankment is now up to its finished height.

4.2 There is still work to be done to finish the final designed profile, install the embankment protection and grass seed the finished surfaces.

4.3 It is currently estimated that work will be completed and the site demobilised by mid- March 2020.

5. Boston Barrier

5.1 The primary Boston Barrier gate was delivered from The Netherlands on the 3rd November and successfully installed and lowered into its open position after being connected to its two hydraulic operational rams and temporary hydraulic systems before Christmas 2019.

5.2 The Barrier has been raised into its full defence position for the first time in order to perform wet testing. The Barrier passed the leakage tests and are now moving onto the ballast tests where the gate will be filled with 400 tonnes of water.

5.3 Scour Protection Mats are being installed upstream and downstream of the Barrier location to manage any potential river erosion that could occur. Once complete, the bypass channel for navigation will be closed and backfilled in order for the barrier to be fully effective with navigation diverted permanently back through the new barrier channel.

5.4 Next steps for the scheme include piling along the existing Port outer quays and installing new flood walls along the boundary of the port estate along with a number of new flood gates followed by the installation of a replacement flood gate at the Port of Boston wet dock entrance in 2021 and associated works at the Maud Foster outfall to tie the project into the current Haven Banks Scheme, an independent project which will raise and strengthen the existing flood banks running from the Barrier towards the Wash for a distance of 5 km.

5.5 The primary Barrier will be fully operational by summer 2020 with the project as a whole programmed to be complete within the 2021/22 financial year.

Policy and Scrutiny

Open Report on behalf of Andy Gutherson, Executive Director – Place

Report to: Flood and Water Management Scrutiny Committee Date: 24 February 2020 Developing a strategy for the sustainable future of the Subject: coast KeyDecision decis Reference:ion? No Summary: The report outlines work to establish a partnerhsip approach to the securing the future of Lincolnshire's coastal areas. This builds on existing public and stakeholder aspirations. It aims to provide a framework to shape and support delivery of strategic objectives in a way that is most appropriate to the coastal context.

Actions Required: The Committee is asked to consider the approach outlined, and provide guidance to officers in continuing to develop the strategy and vision for coastal Lincolnshire.

1. Background

The east coast of Lincolnshire is a key part of the visitor economy, and plays an important part in the county's agriculture, service industries and provision of social care. Understanding how the coast might look in the future, how it will support the long term health and wellbeing of its communities, environment and businesses and how it will best function as a key part of the county and country's environment and economy is essential in deriving decisions about what the most appropriate form of coastal management might be. In effect, when we understand how we wish the coast to work in future, we can better determine how we wish to approach managing the coast and associated flood risk.

This report outlines work in progress to establish a co-ordinated vision for the future of the to help link up and strengthen our shared approach to flood risk management, economic development, housing and housing policy, infrastructure, enhancing the natural environment and supporting the visitor economy. It is intended that this strategy should be developed as a partnership venture, and discussions about it are already in train with the Environment Agency and East Lindsey District Council, with a view to launching the strategic approach in early 2021 to align with commencement of the next phase of coastal management as well as the national Year of the English Coast.

Page 61 Aligning key initiatives

The Environment Agency is currently leading on developing the Saltfleet to Strategy, which will out the future approach to coastal management techniques along the East Lindsey coastline for the next fifteen years. It implements the broad policies established in the 2012 Shoreline Management Plan, and takes account of a wide range of stakeholder views and existing strategies. This approach is incorporated within the Joint Lincolnshire Flood

Risk and Water Management Strategy, and reflects the Greater Lincolnshire LEP's Coastal Vision, as well as the overall economic objectives in the Strategic Economic Plan and the emerging Local Industrial Strategy.

In planning policy terms, the current Adopted Local Plan (July 2018), developed by East Lindsey District Council, takes, in some respects a precautionary approach to flood risk, limiting housing development in coastal zones subject to flood risk to existing commitments. New housing is supported but primarily for affordable housing, conversions and the development of brownfield land. Employment development and development associated with economic growth and tourism is strongly supported but there is a limitation on the occupancy period for caravans over the higher risk winter period. In this respect some forms of development could increasingly become at odds with LEP ambitions to grow and diversify the local economy, including attracting a more diverse and higher skilled workforce to coastal areas.

In September 2019 the Government announced that 100 places were invited to develop proposals for a new generation of multi-million-pound Town Deals, two of those places were on the Lincolnshire coast, being and Skegness, with the potential to unlock £50m of funding for each of those towns. In order to form a clear link with a robust vision for the coast, a review of the Council`s Local Plan is taking place to ensure that growth is directed to and supported in these two communities. It will also enable the LEP ambitions to grow and assist with the narrative that partners are seeking.

Emerging national policy

The draft National Flood Risk and Coastal Management Strategy stresses resilience of place, and offers an opportunity to present a proactive solution at a significant scale which addresses the issue of strategic flood risk resilience as an integral part of supporting the UK national economy by protecting high quality agri-food and visitor economy assets, underpinned by a robust, high quality environment.

For this reason it is important that the vision for the coast supports a strong narrative around potential and future growth, along with an evolutionary vision for development of Lincolnshire's coastal area, while making the case and narrative for continuing investment to enable that evolution. An important part of the strategic approach will, therefore, include a strong and clear case for sustaining its coastal communities and assets, and for promotion of future growth and development in these areas.

Page 62 Scope of strategic approach

In 2015 the Greater Lincolnshire LEP created a coastal vision as a first step towards linking coastal flood risk management policy and emerging economic aspirations for the Greater Lincolnshire coastal zones, from the Estuary to the Norfolk boundary. This has helped to improve the robustness of our evidence base for the present economy of coastal Lincolnshire, and to develop outline ambitions for what it might be in the future.

It will be apparent from the foregoing that full consideration of coastal Lincolnshire and its role and function in the future could involve a very wide range of policy areas and stakeholders. In the interests of maintaining control and clarity it is suggested that it should be relatively tightly defined to focus on a core purpose while allowing for wider engagement and influence where appropriate. It is suggested that the following are the core subject areas around which a strategic vision or approach should be developed:

 Flood risk management & climate resilience  Economic development  Infrastructure & housing planning  Environmental & heritage management  Access and 'brand'

It is also suggested that the initiative should be confined to the east coast from Gibraltar Point northwards to Saltfleet and . This is because the nature of the coast, its natural processes, human geography and economy is very different from the Wash, with correspondingly different methods of coastal management and differing forecast climatic responses. Broadly the area should extend inland to the foot of the Wolds, to link in with current coastal and fluvial flood risk mapping.

In terms of public engagement, a series of prior engagement exercises have been carried out to inform coastal management policies and plans since 2012, including:  2008-2009 Stakeholder consultation on Coastal Study (intended to lead to a coastal strategy as part of regional planning)  2011-12 Stakeholder and public consultation on policies for Shoreline Management Plan  2011-12 Stakeholder and public consultation on emergency planning and potential evacuation of coastal area in emergency situations  2016-19 Stakeholder and public consultation on Saltfleet to Gibraltar Point Strategy

It is suggested that further direct public consultation would reveal little new information and would be unlikely to ask significantly different questions of local communities. The results of these completed exercises should be taken forward and inform the overall direction of the strategic approach through incorporation of existing, ongoing initiatives, and through planned consultation exercises, such as those shaping the review of East Lindsey District Council's Local Plan.

Page 63 At this point it is envisaged that the strategic approach should be a short document, with a small number of core objectives covering a timescale of the next 50-100 years. It should act as a unifying framework, delivered through more detailed initiatives (such as the Gibraltar Point to Saltfleet Strategy and East Lindsey`s Local Plan Review and the national Town Fund), and should have clearly articulated measures so that progress towards the objectives can be identified.

It should provide a bridge between countywide objectives – for example in the LCC's emerging Corporate Plan – and a more distinctive application of those objectives within the specific coastal setting. Success for the strategy will be measured in terms of its adoption as a key document by partners and it will act as evidence of joint working between the District Council, County Council, Environment Agency and other partners in working together to achieve a shared vision and set of objectives for the coast.

Timescales

It is intended to develop the strategic approach with the aim of completion in late 2020, in time for the commencement of the Saltfleet to Gibraltar Point Strategy in April 2021and in alignment with major projects such as the Local Plan review. Preparation of a first draft document in mid-February will commence a period of iterative comment and review, with the aim of producing a reasonably full draft by August 2021.

2. Conclusion

Implementation of a shared strategic approach for the coast of Lincolnshire offers the possibility of establishing a new basis for providing large-scale flood defence structures through a clear approach to the economic, social and environmental vision for a large area of the county.

It provides an opportunity to showcase sustainable place-shaping for the future in a highly challenging environment, and it has the potential to unlock increased investment and growth in the coastal areas of the county, generating the added value that will help to boost investment in ongoing coastal management.

With the forthcoming 2021 Year of the Coast initiative and the UK's hosting of COP26, there is also a significant opportunity to showcase sustainable place- shaping for the future in a highly challenging environment.

Policy and Scrutiny

Open Report on behalf of Andrew Crookham, Executive Director of Resources

Report to: Flood and Water Management Scrutiny Committee Date: 24 February 2020 Flood and Water Management Scrutiny Committee Work Subject: Programme KeyDecision decision? Reference: No Summary: This item enables the Committee to consider and comment on the content of its work programme for the coming year to ensure that scrutiny activity is focused where it can be of greatest benefit. Members are encouraged to highlight items that could be included for consideration in the work programme.

The work programme will be reviewed at each meeting of the Committee to ensure that its contents are still relevant and will add value to the work of the Council and its partners.

Actions Required: The Committee is invited to:

(1) review, consider and comment on the work programme;

(2) highlight for discussion any additional scrutiny activity which could be included for consideration in the work programme; and note the terms of reference of the Flood and Water Management Scrutiny Committee, as agreed by the County Council.

1. Background

Overview and Scrutiny should be positive, constructive, independent, fair and open. The scrutiny process should be challenging, as its aim is to identify areas for improvement. Scrutiny activity should be targeted, focused and timely and include issues of corporate and local importance, where scrutiny activity can influence and add value.

Overview and scrutiny committees should not, as a general rule, involve themselves in relatively minor matters or individual cases, particularly where there are other processes, which can handle these issues more effectively.

Page 67 All members of overview and scrutiny committees are encouraged to bring forward important items of community interest to the committee whilst recognising that not all items will be taken up depending on available resource.
