I have circulated a report to members on the main elements of Limerick County Council's response to the flooding and severe weather conditions in December 2009 and January 2010.
We learned lessons from a devastating flood in July and August 2008 in west Limerick and, as a result, a draft inter-agency plan for flooding was drawn up which was of particular use in setting out the approach to the flood response of December 2009. Both responses were typified by a very high degree of co-operation and co-ordination, both between sections within Limerick County Council and between Limerick County Council and a large number of other responding agencies, affected families, businesses and other entities. As such, they form a model for future interventions of this nature.
The Met Éireann monthly weather summary for November 2009 reported that persistent and often heavy rain and saturated ground conditions led to unprecedented levels of flooding in parts of the west and south. We made our own comparisons for November 2009 and at Shannon Airport, 277% more rainfall was recorded than the average.
The Shannon catchment was particularly badly impacted upon by this prolonged and unprecedented rainfall, all of which ultimately discharges through the ESB-controlled weir upstream of Limerick city. The Office of Public Works has a hydrometric gauge at the ESB's Parteen Weir which digitally records water levels. The water levels recorded here during the month of November 2009 were the highest levels ever recorded by the ESB and the OPW.
The ESB alerted Limerick County Council to the potential increase in discharges late on the afternoon of Friday, 20 November 2009. Recognising the potential for serious flooding arising from increasing discharges, a decision to mobilise the crisis management team was taken that evening and it convened at 9 a.m. on Saturday, 21 November 2009 in county buildings, Dooradoyle. The crisis management team is a tactical-level management group which assembled on a regular basis to manage, control and co-ordinate Limerick County Council's overall response to the flooding. The other principal response agencies, the Garda Síochána, the Health Service Executive and Civil Defence, were also represented in the crisis management centre. Meeting regularly throughout the event, the final meeting of the group took place on 9 December 2009.
The Annacotty area office was used as the on-site co-ordination centre to oversee the operational response to the flooding from 20 November until the winding-up of the operation on 1 December 2009.
The impacted areas in County Limerick stretched from Montpelier village downstream through Castleconnell, Mountshannon and Plassey, to the confluence with the Groody river. Based on available mapping, ESB flood profiles and the An Post Geodirectory system, by early Saturday our staff were able to predict those areas and the numbers of properties most likely to be directly impacted upon by the rising flood waters.
Limerick County Council closed a number of roads in the Montpelier, O'Brien's Bridge and Castleconnell areas. Local diversions were set up and maintained in the areas affected. Two pedestrian bridges in Castletroy and Castleconnell were also closed. Substantial damage was done to roads and footpaths in the Castleconnell and Montpelier areas.
Housing estates at Brookhaven, Montpelier, Meadowbrook and Castleconnell were inundated, as were several individual houses in the area between Montpelier and the Groody river, particularly at Mountshannon lane. A total of 22 families left their properties. A number of farms had large areas of land under water with no fodder for livestock. The farming organisations and Limerick County Council's community and enterprise section were in contact with the farmers to address any animal welfare issues.
The waste water treatment plant situated in Drumore, Castletroy, experienced flooding which was very close to making the plant non-operational. A significant effort was undertaken by Limerick County Council staff in preventing the plant from flooding. This involved the continuous pumping of water for five days during the flood peak. The sewerage plant at Brookhaven, Montpelier was required to be emptied during the flood event.
Limerick County Council's environmental laboratory monitored the drinking water quality in the affected areas throughout the flooding. Although only very low levels of contamination was identified, the HSE advised that a precautionary boil-water notice be put in place for the Montpelier area.
Response to the flooding by the Annacotty area staff commenced on Friday, 20 November 2009 and continued until Tuesday, 1 December 2009. Annacotty crews were assisted by staff from other areas and head office. During the peak operations, 36 staff were deployed, working some 2,010 hours. Approximately 340 tonnes of sand and 20,000 sandbags were used during the flooding. The report also lists the large amount of machinery used by Limerick County Council staff. Additional pumping plant was made available by both the OPW and a local contractor. The fire service also responded to flooding incidents throughout the period.
Accommodation issues arising from the flooding were addressed by the council's housing department, the homeless unit and the Health Service Executive. The response was co-ordinated by the housing department and a total of 22 families had to vacate their houses. No household had to be evacuated by the emergency services. This flooding incident was slow and progressive and this allowed time for Limerick County Council to advise vulnerable households as to the options available to them should they need to vacate their homes. Contingency plans were also put in place with two local hotels and a retirement village complex. I have included a breakdown of the accommodation provided. Some families stayed with relatives, some stayed in rented accommodation sourced by the council, one or two went to retirement homes and nursing homes and one family stayed in bed and breakfast accommodation. Families were assisted financially by the HSE via emergency payments and rent supplement payments. A total of 52 households were affected by flooding and were contacted by the council's housing personnel.
The environment section of Limerick County Council was responsible for assistance with the disposal of flood damaged items. Residents were advised to take appropriate hygiene precautions when handling flood damaged items. An advice leaflet published by the HSE environmental health section was distributed to the residents affected by the flooding. Waterproof gloves and hygienic wipes were provided to the residents by Limerick County Council. Information was provided on the items that were suitable for landfill disposal and those to be collected by the council staff for separate disposal.
The crisis management team used an information management system to capture the evolving events of the flooding. The purpose of the information management system is to assemble available data and to give decision makers relevant information as a sound basis for their decision-making function. The senior engineers, assisted by engineers from Annacotty and other council staff, were constantly reviewing the situation and reporting back to the crisis management team. The director of transportation and water services attended the daily mid-west interagency group meetings which were hosted by Clare County Council in Ennis. The director liaised between that group and Limerick County Council's crisis management team. Regular daily updates were provided by ESB staff from Parteen who attended meetings in Limerick and Ennis. Shannon Development and the University of Limerick received regular updates on known and predicted impacts on Plassey technology park and the university campus. Limerick County Council staff engaged in regular liaison with University of Limerick buildings staff in relation to water, waste water and other matters.
Many communications channels were used throughout the emergency. The Limerick County Council out-of-office hours emergency helpline was used to assist the public with any queries about the flood. The Annacotty area staff also operated a helpline service during the peak flood. In addition to regular communication with individual councillors, a briefing meeting was arranged for the Castleconnell electoral area committee. The housing and community and enterprise sections of Limerick County Council maintained close contact with residents who were forced to evacuate their homes. Two meetings were held in the Castle Oaks Hotel to discuss the impact of the flooding and to assist residents in any way possible. A further meeting was held with the Castleconnell and Montpelier community council. Limerick County Council, the Garda Síochána and the Health Service Executive were represented at those meetings. ESB representatives and an insurance adviser attended the meeting on 5 December. The local residents in attendance appreciated the meetings and complimented Limerick County Council on its response to the flooding.
A text messaging service was set up to provide daily messages to members of the crisis management team and people in the community who were affected by the flooding. Regular press releases were issued to local and national media organisations to update people on the status of the flooding and to distribute public interest messages, such as health advice and boil water notices. The assistance of the media, particularly local radio and press, was greatly appreciated. A link on the website of Limerick County Council, www.lcc.ie, gave members of the community up-to-date information and advice on the flooding. The website set out the actions people needed to undertake if forced to evacuate their homes, details and status of road closures, advice on returning to and cleaning properties, and boil water notices. The council received full reimbursement of its initial response expenditure of €180,300 from the Department of the Environment, Heritage and Local Government’s supplementary funding mechanism. It did not receive any additional funding in respect of infrastructural damage and remedial works which have been estimated at €1.2 million.
I wish to speak about the severe weather event of December 2009 and January 2010. A spell of cold weather commenced on 18 December 2009 and continued until mid January 2010. This was the most prolonged cold snap since 1963, with temperatures dropping to as low as -13°Celsius. The adverse weather conditions led to heavy falls of snow throughout the county, with west Limerick being particularly affected. Limerick County Council operates an ice prediction system, Icecast, in conjunction with the National Roads Authority. The system, which provides real-time weather monitoring on national roads, has been in use for almost ten years. The system is monitored by rostered engineers who activate the appropriate response on the basis of information from the system and their own judgment. Pre-salting of roads in advance of freezing temperatures is the usual response and is a regular feature of the winter maintenance programme. Salt lowers the temperature at which water freezes and inhibits the crystallisation of water particles into ice. More frequent treatment may be needed, however, depending on variations in weather conditions and the severity of the cold snap in question. During the recent weather event, it was sometimes necessary to salt the roads up to three times in a 24-hour period.
Limerick County Council had prepared well by stockpiling more than 800 tons of salt by the beginning of December, with additional supplies on order. As the cold snap extended and the European and national shortage of salt became apparent, it was necessary to prioritise the salting programme. Priority was given to national primary and secondary roads, regional roads and primary local roads. This covered over 20% of the road network and accounted for approximately 80% of the traffic. Regional roads did not receive the same intensity of salting as national roads. Salt is stocked in strategic depots throughout the county. The dedicated winter maintenance equipment includes six large gritters, six small gritters, five snow ploughs and five graders that are effective as snow ploughs. The council's machinery and equipment has been upgraded and subject to preventative maintenance and calibration. Over the Christmas and new year period, council staff worked day and night to maintain the fleet in good working order, to avoid breakdowns and to ensure roads were treated as required every day.
Interagency meetings were arranged with representatives of the Garda, the HSE ambulance service, the fire services, the Civil Defence and the Defence Forces. The media were used to disseminate regular bulletins, interviews and warnings. Elected members were briefed throughout the period of cold weather. Tributes were paid to all staff at a specially convened council meeting. I thank all the organisations that helped Limerick County Council deal with the severe conditions. In addition to keeping national, regional and primary local roads open, priority was given to addressing hardship cases and specific locally identified situations, including medical emergencies and funerals. The county council succeeded in keeping national, regional and local primary roads open and most county roads were passable with care.
The total cost of the winter maintenance operation to date has been €450,000. This expenditure will be met, in part, through the NRA winter maintenance fund for national roads. A significant part of the cost will be met from the non-national road allocation, which is already seriously stretched. The condition of the road network following the severe weather conditions is of major concern. The cost of repairing frost-related roads is estimated at €4.2 million. This has been relayed to the appropriate Departments. While some additional funding has been provided for national roads, no additional funding has been made available for non-national roads. The council will make every effort to carry out the necessary repairs on a priority basis, within the resources available to it.
Water services throughout the county were also affected by the severe weather. There was an increase in water demand during the period of severe weather. The thaw which began around 11 January further exacerbated the water demand and supply issues. Water demand in water schemes around the county rose by 20% or more, with increases of 50% in some supplies. The service pipes to a number of houses froze, thereby depriving households of water. The council acknowledges the spirit of co-operation between households in providing water to neighbours whose pipes had been affected. Repair crews were called out throughout the Christmas period, including some calls on Christmas Day. Apart from sections of the Abbeyfeale supply, water supplies were maintained without undue impact on customers and despite increased demand. Water tankers were deployed to Mountcollins, Athea, Abbeyfeale and Tournafulla in west Limerick when water outages affected outlying areas of the Abbeyfeale scheme. Tankers in these areas were stood down when supplies were restored.
In seeking to maintain supplies through the thaw, Limerick County Council set about reducing demand to meet available supply by finding and fixing leaks. Priority was given to schemes where the imbalance between demand and supply was highest. Long after normal consumer service was restored, a considerable effort continues to be made to deal with frost related leaks in the system as the council seeks to minimise water that is not accounted for. Some of the lessons we need to learn for the future have already been mentioned. While Limerick County Council is reasonably satisfied with its response to the flooding and severe weather events, a number of issues need to be addressed. As I said earlier, the council's draft flood plan, which will be the blueprint for our response to events of this kind, needs to be completed as soon as possible. Consideration needs to be given to the rationalisation and co-ordination of salt purchase, storage and distribution. The issue of pedestrian safety, particularly in large urban areas, needs further examination in the context of severe weather events. Issues surrounding the use of community groups, including health and safety and insurance implications, need to be clarified at national level. Under the present structures, it was not possible for Limerick County Council to deal with all the 400 km of footpath for which it has responsibility.
I would like to speak briefly about the Shannon river basin management plan for which Limerick County Council is the lead authority. Under the EU water framework directive, which was agreed in 2000, river basin management plans must be prepared. These cover the entire EU. There are eight river basin districts covering the island of Ireland, including the Shannon river basin district, the largest at more than 18,000 sq. km in area. It stretches from its source in the Cuilcagh Mountains in County Cavan to the tip of the Dingle Peninsula.
Limerick County Council is designated as the co-ordinating authority for the Shannon river basin management plan. Up to 17 counties and Limerick city are involved in the plan which has been in preparation since 2004. It is expected the plan will be formally adopted by the individual councils in the coming months. The adoption of plans is a reserve function of local authority members.
In addition to the democratic involvement of the local authorities, an advisory council has been established in each river basin district. The Shannon river basin advisory council consists of 36 county and city councillors, SPC members representing each of the 18 major local authorities, seven representatives of town councils and ten representatives from the farming, fishing, recreation and environmental sectors. It was first established in 2006 and the life of the council is the same as that of the county council. Its role is to consider matters relating to the preparation of the river basin management plans and other matters relevant to the protection of the aquatic environment and water resources in the district and to advise and make recommendations on these matters to the relevant public authorities.
The water directive specifies member states must ensure their waters achieve at least good status by 2015 and that the status does not deteriorate. Waters include rivers, canals, lakes, reservoirs, protected areas, wetlands and coastal waters.
The river basin plan gives the current status of the Shannon waters, specifies the targeted status by 2015 and outlines the means by which this will be achieved. The overall plan, which must be adopted by the 18 local authorities, will include strategic measures to address points and diffuse sources of pollution. Obviously, major national investment will be required to achieve the targets in the timeframes.
The scope of the plan does not extend to flooding. That is covered by the floods directive which requires flood risk management plans to be in place by 2015 and which will be the responsibility of the Office of Public Works. The flooding of the Shannon callows is not the responsibility of the river basin management advisory council or Limerick County Council.
