Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
1.0 Introduction to the Strategic Flood Risk Assessment
1.1 Introduction
Kerry County Council has prepared the Draft Tralee Municipal District Local Area Plan in accordance with the requirements of the provisions of the Planning and Development Act 2000 (as amended), in conjunction with the Regional Planning Guidelines for the South West 2010 – 2022 and the Kerry Count Development Plan 2015 – 2021. The Local Area Plan sets out the landuse framework for the development of the Tralee Municipal District. This Strategic Flood Risk Assessment (SFRA) of the Draft Tralee Municipal District Local Area Plan and Variation to Tralee Town Development Plan 2009 - 2015 (as extended) has been prepared in accordance, in so far as practicable, with the requirements of “The Planning System and Flood Risk Management: Guidelines for Planning Authorities”, published in November 2009 by the DEHLG and the OPW, and having specific regard to the areas, within the settlements of this Municipal District, that have been identified as being at risk of flooding. Flooding is a natural process that can happen at any time in a wide variety of locations. Flooding has significant impacts on human activities; it can threaten people’s lives, their property and the environment. Assets at risk can include housing, transport and public service infrastructure, commercial, industrial and agricultural enterprises. The health, social, economic and environmental impacts of flooding can be significant and have a wide community impact. This SFRA also provides a strategic assessment of flood risk using existing information and data sources to inform strategic land-use planning decisions. As part of this, the Local Area Plan and the Variation to Tralee Town Development Plan 2009-2015 (as extended) as well as the SFRA provide guidance for the identification and zoning of development lands, so as to ensure that flood risk management forms an integral component of the plan formulation process. Guidance is also provided for project level assessment and sustainable flood risk management. Data likely to emerge from the Catchment Flood Risk Assessment and Management (CFRAM), the Irish Coastal Protection Strategy Study (ICPSS) and similar flood risk processes over the coming years will also inform future assessments and decision making. This SFRA has been integrated with the Strategic Environmental Assessment (SEA) process.
1.2 Scope and objectives
This report sets out how the Flood Risk Assessment was undertaken, as well as how its findings were addressed and integrated into the Tralee Municipal District Draft Local Area Plan and the Variation to Tralee Town Development Plan 2009 - 2015 (as extended). The report should be read in conjunction with the Local Area Plan, and the associated maps. The primary purpose of the SFRA is to determine flood risk within a geographical area, in this instance, the Tralee Municipal District and to support spatial planning
Tralee MD SFRA Page 4
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
decisions in relation to the zoning of particular areas or lands for development. Under the Guidelines the objectives of an SFRA is to:
• To provide for an improved understanding of flood risk issues within the Local Area Plan and development management process, and to communicate this to a wide range of stakeholders;
• To consider existing flood defence infrastructure and the consequences of failure of that infrastructure and also identification of areas of natural floodplain to be safeguarded;
• To produce a suitably detailed flood risk assessment, drawing on and extending existing data and information, leading to a suite of flood risk policies and objectives and where appropriate maps that support the application of the sequential approach;
• To inform, where necessary, the application of the Justification Test;
• To conclude whether measures to deal with flood risks to the area proposed for development can satisfactorily reduce the risks to an acceptable level while not increasing flood risk elsewhere, and
• To produce guidance on mitigation measures on how surface water should be managed and appropriate criteria to be used in the review of the Local Area Plan site specific flood risk assessments.
This SFRA takes into account the latest flood risk information/data available from the OPW and national guidance available.
1.3 Disclaimer
This SFRA has been prepared in compliance with the Guidelines but the SFRA remains a living document and is based on the best available data at the time of preparation. It is subject to change based on more up to date and relevant flood risk information becoming available during the lifetime of the Tralee Municipal District Local Area Plan and the Variation to Tralee Town Development Plan 2009 - 2015 (as extended). Accordingly, all information in relation to flood risk is provided for general policy guidance and may be updated in respect of emerging new data and analysis. Owners/occupiers, developers and any other interested body are advised to take all reasonable measures to assess the flooding vulnerability or risk of lands in which they have or may have an interest prior to making planning or development decisions. The aim of this SFRA is to provide an appraisal of all sources of flooding within the Tralee Municipal District area and to set out a number of approaches in the plan making process to avoid, reduce and manage flood risk as part of a wider objective to ensure the protection of property, people and infrastructure. The SFRA does not contain advice for existing occupiers who currently live in areas at risk of flooding or those that may experience flooding.
1.4 Reporting Structure
Section 2.0 of this report provides a brief introduction to the Tralee Municipal District, identifying the settlement hierarchy and the key population and household growth targets for the respective categories of settlement with the settlement hierarchy.
Tralee MD SFRA Page 5
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
Section 3.0 examines the main sources of flood risk within the Municipal District and recent flood events. Section 4.0 examines how the issue of managing flood risk was addressed in the review of the Local Area Plan and outlines the main provisions of the flood risk management strategy. Section 5.0 sets out what this assessment has achieved in terms of managing the
adverse effects of flooding within the Tralee Municipal District. It also identifies how
information on flood risk will be reviewed and monitored over the lifetime of the Local Area Plan.
1.5 The Planning System and Flood Risk
“The Planning System and Flood Risk Management: Guidelines for Planning Authorities”, published in November 2009, describe flooding as a natural process that can occur at any time and in a wide variety of locations. Flooding can often be beneficial and many habitats rely on periodic inundation. However, when flooding interacts with human development, it can threaten people, their property and the environment. Flooding may be from rivers, the sea, groundwater, sewers or overland flow caused by intense or prolonged periods of rainfall. Climate change and its impact in relation to frequency, pattern and severity of flooding is recognised as becoming more uncertain and more damaging. Understanding flood risk is a key step in managing the impacts of flooding. The Guidelines describe good flood risk practice in planning and development management and seek to integrate flood risk management into the planning process, thereby assisting in the delivery of sustainable development. Planning authorities are directed to have regard to the Guidelines in the preparation of Development Plans and Local Area Plans, and for development management purposes. For this to be achieved, flood risk must be assessed as early as possible in the planning process. Paragraph 1.6 of the guidelines states that the core objectives are to:
• Avoid inappropriate development in areas at risk of flooding;
• Avoid new developments increasing flood risk elsewhere, including that which may arise from surface run-off;
• Ensure effective management of residual risks for development permitted in floodplains;
• Avoid unnecessary restriction of national, regional or local economic and social growth;
• Improve the understanding of flood risk among relevant stakeholders; and,
• Ensure that the requirements of EU and national law in relation to the natural environment and nature conservation are complied with at all stages of flood risk management".
The guidelines aim to facilitate “the transparent consideration of flood risk at all levels of the planning process, ensuring a consistency of approach throughout the country. The Guidelines work on a number of key principles, including:
Tralee MD SFRA Page 6
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
• Adopting a staged and hierarchical approach to the assessment of flood risk;
• Adopting a sequential approach to the management of flood risk, based on the frequency of flooding (identified through Flood Zones) and the vulnerability of the proposed land use.
1.6 Definition of Flood Risk
In order to manage flood risk it is important to understand what the term “flood risk” implies and to define the components of flood risk in order to apply the principals of the DEHLG 2009 Guidelines 'The Planning System and Flood Risk Management'. Flood risk is generally accepted to be a combination of the likelihood of flooding and the potential consequences arising, and is normally expressed in terms of the following relationship: Flood Risk = Probability of Flooding x Consequences of Flooding It is assessed using the source – pathway – receptor model as illustrated in Figure 1.1 below. This is a standard environmental risk model common to many hazards and should be the starting point of any flood risk assessment. Figure 1.1 Source-Pathway-Receptor Model
Source: Planning System and Flood Risk Management (DEHLG 2009)
Principal sources of flooding are intense or prolonged rainfall or higher than normal sea levels while the most common pathways are rivers, drains, sewers, overland flow and river and coastal floodplains and their defence assets. Receptors can include people, their property and the environment. All three elements must be present for flood risk to arise. Mitigation measures, such as defences or flood resilient construction, have little or no effect on sources of flooding but they can block or impede pathways or remove receptors. Flood risk assessments require identification and assessment of all three components:
• The probability and magnitude of the source(s) (e.g. high river levels, sea levels and wave heights);
Tralee MD SFRA Page 7
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
• The performance and response of pathways and barriers to pathways such as floodplain areas and flood defence systems, and
• The consequences to receptors such as people, properties and the environment. The planning process is primarily concerned with the location of receptors, taking appropriate account of potential sources and pathways that might put those receptors at risk.
1.7 Probability of Flooding
The likelihood of flooding is normally expressed as the percentage probability based on the average frequency measured or extrapolated from records over a large number of years. A 1% probability indicates the flood level that is expected to be reached on average once in 100 years, i.e. it has a 1% chance of occurring in any one year. Considered over the lifetime of development, such an apparently low-frequency or rare flood has a significant probability of occurring. For example:
• A 1% flood has a 22% (1 in 5) chance of occurring at least once in a 25-year period - the period of a typical residential mortgage;
• And a 53% (1 in 2) chance of occurring in a 75-year period - a typical human lifetime.
In the Department document 'Planning System and Flood Risk Management', the likelihood of a flood occurring is established through the identification of Flood Zones which indicate a high, moderate or low risk of flooding from fluvial or tidal sources, as defined in Table 1.1. It is important to note that the Flood Zones do not take other sources of flooding, such as groundwater or pluvial, into account, so an assessment of risk arising from such sources should also be made, where appropriate. Table 1.1 Definitions of Flood Zones Flood Zone Description
Zone A High probability of Flooding
More than 1% probability (1 in 100) for river flooding and more than 0.5% probability (1 in 200) for coastal flooding. Most types of development would be considered inappropriate in this zone.
Zone B Moderate probability of Flooding
0.1% to 1% probability (between 1 in 100 and 1 in 1000) for river flooding and 0.1% to 0.5% probability (between 1 in 200 and 1 in 1000) for coastal flooding. Highly vulnerable development, such as hospitals, residential care homes, Garda,
Tralee MD SFRA Page 8
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
fire and ambulance stations, dwelling houses and primary strategic transport and utilities infrastructure, would generally be considered inappropriate in this zone.
Zone C Low probability of Flooding
This zone defines areas with a low risk of flooding from rivers and the coast (i.e. less than 0.1% probability or less than 1 in 1000). Development in this zone is appropriate from a flooding perspective (subject to assessment of flood hazard from sources other than rivers and the coast).
Figure 1.2 Example of Flood Zone Mapping
Source: Planning System and Flood Risk Management (DEHLG 2009)
1.8 Consequences of Flooding
Consequences of flooding depend on the hazards caused by flooding (depth of water, speed of flow, rate of onset, duration, wave-action effects, water quality) and the vulnerability of receptors (type of development, nature, e.g. age-structure, of the population, presence and reliability of mitigation measures etc). The DEHLG 2009 Guidelines 'The Planning System and Flood Risk Management' provides three vulnerability categories, based on the type of development, which are detailed in Table 3.1 of the Guidelines, and are summarised as:
• Highly vulnerable, including residential properties, essential infrastructure and emergency service facilities
Tralee MD SFRA Page 9
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
• Less vulnerable, such as buildings used for retail and commercial and local transport infrastructure
• Water compatible, including amenity open space, outdoor recreation and associated essential infrastructure, such as changing rooms.
1.9 The Staged Approach
The Guidelines recommend a staged approach to be adopted to ensure that only such an appraisal or assessment as is needed for the purposes of decision making at the various plan levels is undertaken. The stages include: Stage 1: Flood risk Identification: To identify whether there may be any flooding or surface water management issues related to the area of the regional planning guidelines, development plans or local area plans (LAPs) or a proposed development site that may warrant further investigation at the appropriate lower level plan or planning application levels. If the Planning Authority considers that there is potential flood risk issue, then stage 2 shall be entered into. Stage 2: Initial flood risk assessment: To confirm sources of flooding that may affect a plan area or proposed development site, to appraise the adequacy of existing information and to scope the extent of the risk of flooding which may involve preparing indicative flood zone maps. Where hydraulic models exist, the potential impact of a development on flooding elsewhere and of the scope of possible mitigation measures can be assessed. In addition, the requirement of the detailed assessment should be scoped; and Stage 3: Detailed flood risk assessment: To assess flood risk issues in sufficient detail and to provide quantitative appraisal of potential flood risk to a proposed or existing development or land to be zoned, of its potential impact on flood risk elsewhere and of the effectiveness of any proposed mitigation measures. This staged approach is recommended for flood risk assessments at Regional, County and site-specific levels. Within this hierarchy of Regional, County and site-specific flood-risk assessments, a staged approach ensures that the level of information is appropriate to the scale and nature of the flood-risk issues and the location and type of development proposed, avoiding expensive flood modelling and development of mitigation measures where it is not necessary.

2.0 Study Area
2.1 Introduction
This Section provides an overview of the study area, on which the impact of flooding will be determined in this SFRA. The study area comprises of the Tralee Municipal District, as illustrated in Figure 2.1 below. It is a predominately rural Municipal District that accommodates an extensive network of settlements as follows:
• One Hub Town comprising of Tralee.
• One District town comprising of Ardfert.
• Three Villages comprising of Brosna, Fenit and Knocknagoshel.
• Two Small Villages comprising of Blennerville and Camp.
• Four Development Nodes comprising of Ballymacelligott, Clogher, Lyracrumpane and Spa.
The Tralee Municipal District lies within the South West (Planning) Region, and is currently covered by the Regional Planning Guidelines (RPGs) for the South West Region 2010 – 2022. A Regional Flood Risk Appraisal (RFRA) for the South West was undertaken as part of the development of the RPGs. Figure 2.1 Tralee Municipal District

2.2 Population and Household Growth
The Tralee Municipal District covers an area of approx 59,590 Ha and has an existing population of 39,747 people according to the 2016 Census. The Kerry County Development Plan 2015 – 2021 provides for a growth in population of 3,480 persons corresponding to an allocation of 1,135 housing units up to the year 2021. This level of housing provision is primarily in the main towns, with additional housing opportunities in the villages and rural areas. The majority of growth is allocated to the towns, with 1,142 new houses proposed in Tralee, the designated Hub Town in the National Spatial Strategy and in line with the South West Regional Planning Guidelines. Housing growth is also planned within the villages and smaller settlements. The distribution of projected growth throughout the County is in accordance with the Core Strategy and the settlement hierarchy outlined in Section 3.1 of the Kerry County Development Plan 2015 – 2021. Table 2.1 below outlines the population allocation for the individual settlements of the Municipal District provided for in this Local Area Plan.

2.3 Environment and Heritage
A significant percentage of the Tralee Municipal District is located within a designated site of nature conservation importance. Sites of importance include Natura 2000 site designations (SAC and SPA), Natural Heritage Areas (NHA), Proposed Natural Heritage Areas (pNHAs) and Ramsar sites. Up to date maps and details of these are available on line at www.npws.ie or from the National Parks and Wildlife Service (NPWS), who are the lead agency for nature conservation in Ireland. European and National Legislation now protects the most valuable of our remaining wild places, through the designation of these sites as proposed Natural Heritage Areas, Candidate Special Areas of Conservation and Special Protection Areas. The current list of protected sites is contained in the County Development Plan 2015 - 2021 and is shown on the Heritage and Scenic Amenity Maps in Volume 3 in that Plan. Designated sites in the Tralee Municipal District are detailed in the table below. Table 2.2 Designated Sites in the Tralee Municipal District

Sites of geological of interest have not been covered comprehensively to date by the existing nature conservation designations. Kerry County Council recognises the importance of geological heritage and to this end has listed the important geological features within the county, in the County Development Plan 2015 – 2021, with the intention of maintaining their possible conservation value. Geological features of interest in the Tralee Municipal District include; Waulsortian build-ups with Lithistid demosponges at Carrahane Strand in Barrow, residual and tertiary tower karst in Barrow, Waulsortian mud mound at Samphire Island in Fenit, Fenit Island, Ballymacelligott Caves System, Fauna and striped limestone at Oyster Hill in Fenit, Carboniferous mound at Plover Hill in Tralee/Fenit, Camp valley, Mass Wasting in Fenit/Kilfenora/Spa, Ardfert Quarry and Tombolo and dunes in Barrow Harbour. A full list of geological sites of interest identified by the geological Survey of Ireland (GSI) is outlined in Appendix IV, Table 10.6 in the County Development Plan 2015 - 2021. In terms of built heritage, there are numerous recorded monuments and protected structures throughout the Municipal District and these are also detailed in the County Development Plan 2015 – 2021.
2.4 Infrastructure
Infrastructural deficiencies within the Municipal District will need to be addressed in terms of waste water treatment and water supply over the lifetime of the Local Area Plan if the growth targets for the electoral area are to be achieved. Particular infrastructural improvements will include upgrading of waste water treatment plant facilities and implementing water conservation measures across the Municipal District.

3.0 Identifying Flood Risk in the Tralee Municipal District
3.1 Sources of Flooding
This SFRA has primarily reviewed flood risk from fluvial sources, (i.e. flooding from a river or other watercourses). Flood risks from pluvial flooding (i.e. flooding as a result of rainfall-generated overland flows which arise before run-off enters any watercourse or sewer), groundwater sources or from drainage systems, reservoirs and canals and other artificial or man - made systems have not been considered in detail in this study and such risks will need to be assessed at the project stage. This approach has been adopted for two reasons. Firstly, the review of flooding in the Tralee Municipal District shows rivers to be the most common source of damage and it is this source of flooding that has been taken into account in the Local Area Plan process. Other sources of flooding are considered to present a lesser risk in this Municipal District but should be considered at the planning application stage. Secondly, Flood Zones in the 'Planning System and Flood Risk Management' are defined on the basis of fluvial, and where appropriate, tidal flood risk.
3.2 Fluvial Flooding
Flooding of watercourses is associated with a channel exceeding capacity during higher flows. The process of flooding on watercourses depends on a number of characteristics associated with the catchment including; geographical location and variation in rainfall, steepness of the channel and surrounding floodplain and infiltration and rate of runoff associated with urban and rural catchments. There are two main catchment types; large and relatively flat or small and steep. These give two very different responses during large rainfall events. In a large, relatively flat catchment, flood levels will rise slowly and natural floodplains may remain flooded for several days, acting as the natural regulator of the flow. In small, steep catchments, local intense rainfall can result in the rapid onset of deep and fast-flowing flooding with little warning. Such “flash” flooding, which may only last a few hours, can cause considerable damage and possible threat to life. The form of the floodplain, either natural or urbanised, can influence flooding along watercourses. The location of buildings and roads can significantly influence flood depths and velocities by altering flow directions and reducing the volume of storage within the floodplain. Critical structures such as bridge and culverts can also significantly reduce capacity creating pinch points within the floodplain. These structures are also vulnerable to blockage by natural debris within the channel or by fly tipping and waste. Rivers are the primary cause of flooding in the Tralee Municipal District with flood events attributed to fluvial sources ranging from the River Lee and Big River to smaller tributaries and drains.
Tralee MD SFRA Page 15
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
3.3 Rivers in the Tralee Municipal District
The River Lee, which flows through Tralee town and enters Tralee Bay approximately 10 km east of Fenit has two main tributaries, the River Big and Balloonagh. These two tributaries drain the steeply sloping ground to the north of Tralee. There are also a number of smaller tributaries such as the Finglas River, the Derrymore River, the Derryquay River and the Curraheen River, which flow into Tralee Bay from the Dingle Peninsula, to the south of Fenit bathing waters. The River Lee itself flows west along the southern edge of the town, before entering an extensive tidal to the west. The River Lee is at risk of fluvial flooding.
The Big River Corridor and its tributary, which comes from the northeast environs runs to Tralee town centre. The Big River is at risk of fluvial flooding.
The Tyshe River flows north of Ardfert from an east to west direction where it has an extensive network of tributaries. It then turns north through Banna and ultimately discharges to the estuary in the townland of Ballinprior (at Black Rock), between Banna and Ballyheige. The Smearlagh River, a tributary of the River Feale and the Crumpane River are located in located in the Stack's Mountains in North Kerry and the rivers converge just downstream from Lyracrumpane Bridge.
The Glena River, Tullaleague river and the Owveg River, a tributary of the River Feale, are located in the lowlands surrounding Knocknagashel village.
The Shanow River, a tributary of the River Feale flows north, north-west along the boundary of the Tralee Municipal District.
The Clydagh River flows west of Brosna where it meets the River Feale.
Other rivers under consideration in the Tralee Municipal District are, the Tullaleague River and the Glanshearoon Stream the south of Knocknagashel, the Glanagenty River, the Emlagh River, the Glashacooncore River, the Glannadarriv Stream, the Glenagharan Stream, the Cloon River and the Little River Maine.

3.4 Historical Flood Events
Tralee town centre used to be flooded more often before 1986. However, after a severe flood in August 1986 a major flood relief scheme was constructed to alleviate the problem. However, discussions with OPW indicate that some areas still appear to be at risk of flooding. The main sources of flooding in Tralee and its surrounding area are the two tributaries of the River Lee, the Big and Balloonagh Rivers. These two tributaries drain the steeply sloping ground to the north of the town. Due to the underlying geology of limestone, small size and steepness of the catchments, storm flows in the Big and Balloonagh Rivers were characterised by short times to peak, short duration and high peak value resulting in flash flooding. For detailed information on causes of flooding and the extent of flood in August 1986 refer to a report “Tralee Flood & Development Study” prepared by M C O’Sullivan Consulting Engineers in October 1987. There are two gauging stations in this catchment, one in the River Lee and the other in one of its tributaries, the Big River. The gauging station on the Big River is managed by the Environmental Protection Agency (EPA) whilst the gauging station on River Lee is managed by OPW. The data from Big River gauging station was not available at the time of preparing this report. Only 18 years (1975 to 1992- hydrometric year) annual maximum flow is available from Ballymullen (23012), the gauging station on River Lee. The Ballymullen gauging station records flow from a catchment area of about 62km2. Because of the limited number of annual maximum flow records available, the flow of events that occurred outside the period of 1975 to 1992 hydrometric years and their associated AEP cannot be estimated. The recurrence of flood event in the town centre has improved after major drainage works following the severe flooding event of August 1986. However areas outside the town centre appear to be flooded regularly. Most of the floods in Tralee appear to have been caused due to overgrowth in the banks of the river channels, inadequate capacity of culverts along the River Lee and its two tributaries the Big and Balloonagh rivers. In the section below the historical recorded flood events and their causes and sources are described briefly. Flood events are known to have occurred quite often in two areas around Tralee, namely Ballinorig and Caherleheen, as well as Ardfert, several km northwest of Tralee. The flooding problem in Ballinorig appears to have been caused by inadequate capacity of a culvert under the N21 Castleisland to Tralee road at Clashlane roundabout which causes a stream to overflow in the vicinity of houses at Ballinorig. The recurrence of flooding in this area is reportedly almost annual. Flooding in Caherleheen occurs almost once per year, mainly along the N70 (Tralee to Castlemaine) road and the surrounding land. The cause of flooding appears to be heavy rainfall over a long period of time which results in the limestone subterranean caves and caverns overflowing. This is exacerbated in some cases by backwater effects caused by high tides. In Ardfert the R551 road is flooded 3 to 4 times per year. The flood in this area affects 10 houses. The cause of the flood in this area is surface runoff from steep land at the south east of the village running into the road and lack of adequate drainage to safely collect the runoff. The flooding is not from the Tyshe River which flows just to the north of Ardfert.
Tralee MD SFRA Page 17
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
Recent significant flood events have included:
December 2015 On December 4th & 5th flooding occurred during Storm Desmond. Dwellings at a number of estates in Tralee flooded with significant pluvial flooding occurring in Ballymullen. During the storm, the River Lee recorded levels of between 77mm and 114mm over a 36 hour period, the highest level since the installation of the gauge in 1975, exceeding the previous high in 1986. February 2011 Flooding occurred in Kearney’s Road in the Blennerville area on 18th February 2011 mainly due to tidal flooding in the River Lee Estuary. November 2009 The flooding in Curragraigue started on 19th November and lasted until 26th November 2009. Exceptional high rainfall caused surface runoff. The existing culvert failed to cope with the excess surface runoff generated. The flood was level estimated to be about 3.3mAOD (1.0m deep). On the same day the area from Army Barracks to Ballymullen roundabout in Balleymullen was flooded. The flood in this area lasted for a day. Similar to Curragraigue a rainstorm generated surface runoff beyond the capacity of the combined sewer system in the vicinity of this area. The flood affected 6 residential properties and 1 commercial or public property. It also caused major disruption to transport. August 2008 South West of Tralee, Caherweesheen, Ballyard a flooding event was reported on 13 August 2008. The flood lasted for two days. The source of the flood was surface water runoff during exceptionally heavy rainfall which caused overflow of river banks. The capacity of the river was restricted by culverts/pipes along the section of the river. This flood impacted 1 house and a farm building. August 1997 On 31 August 1997 severe flooding occurred in Tralee area. The Tralee Killarney Road was flooded and closed to traffic at Ballycarthy cross and the Earl of Demon hotel was flooded. Flooding also occurred at Ardnabraher Ballinorig where 3 houses were flooded to a depth of 3 feet. November 1996 On 24 November 1996 flooding occurred in Balleyseedy. The flooding problem in Ballyseedy area was mainly caused due to overgrowth on the river bank and the narrow nature of the river around this area. August 1986 Excess rainfall on 5 August 1986 caused the Big River to overflow and burst its bank at a point in the vicinity of the railway station where the channel is culverted under the town. This caused severe flooding in Tralee. The peak flow at Princes Quay and Denny Street at the time of flooding was 10m3/s and 27.5m3/s compared against the design capacity of 9m3/s and 18.2m3/s respectively. Severe flooding was also experienced in Ballymullen and Castlecountess areas along the main River Lee. This flooding event coincided with
Tralee MD SFRA Page 18
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
the storm hurricane Charley, a major metrological event that occurred in Ireland in August 1986. November 1980 On 2 November 1980 flooding occurred in Ballyseedy, Ballyard and on the Big River at Oakview and the railway road near Ashe Street. This event is recorded as a major weather event in http://www.met.ie (the Met Eireann website). In addition flooding also occurred in Ballymullen at three locations. The first location was in Killerisk, the second location was opposite the Army Barrack and the third location was in Castlemaine road. The flooding in Killerisk was caused due to inadequate capacity of the culvert that discharges runoff from the area to the River Lee. The area around the Trace House opposite the Army Barrack was flooded as a result of over bank flow. The flooding in Castlemaine road was caused by restriction in capacity of a drain located on the east side of the Castlemaine road. The drain is crossed by an access road to a private house and a filling station. The culverts under the access road appear to have restricted the capacity of the drain and hence caused flooding to the Castlemaine road. The 3 November 1980, was only flood event recorded in Banna. This flooding was due to the coincidence of the heavy rain with high tides. The main Ballyheigue – Ardfert Road was flooded to a depth of approximately 0.15m (0.5ft). December 1973 The 1 December 1973 flood event resulted from heavy rains in the previous days which saturated the ground and reduced its capacity to absorb water. The entire business area of Tralee was flooded in some areas the flood reached a depth of about 0.6m. The coincidence of the heavy rain with a high tide exacerbated the flooding condition in the low lying areas of Tralee. However, the effect of the tide was for a short duration and not major when compared with the fluvial and groundwater flooding. Detailed information about the 1973 flood in Tralee can be found in the flood study report titled “The Tralee 1st December 1973 Report” prepared by McCarthy & Partners Consulting Engineers January 1974. This report also discusses various options for alleviating flooding problems in the area. Other flood events have included: There is one recurring OPW flood record from 2005 for Ardfert. From the report; “The R551 running through the village of Ardfert is flooded 3/4 times per] year. 10 houses are affected. The cause of the problem is heavy rainfall and consequent surface water runoff from steep land at the south east of the village running onto road and lack of adequate drainage for this runoff. Improvements required are adequate drainage from village to the North/ North West.” There are no OPW flood records for the Banna area the nearest is located south in Carrahane. From the OPW flood report on the Carrahane: “This area is near Ballyheige and drained by the same system. A stretch of road which connects the L10481 to the L6095 and is not in public ownership floods on a regular basis, several times per year. Road is not passable. The cause of the flooding is tidal.” There are no OPW flood records for the Fenit area.

3.5 Other Sources of Flooding
Other sources of flooding including pluvial, groundwater, drainage systems and reservoirs are detailed below. Risks from these sources have not been specifically considered in the Strategic Flood Risk Assessment undertaken for the Tralee Municipal District Local Area Plan and need to be addressed at the planning application stage.
• Pluvial Flooding: Pluvial flooding is a result of rainfall generated overland flows which arise before run-off enters any watercourse or sewer. The intensity of rainfall can be such that the run-off totally overwhelms surface water and underground drainage systems. Flooding of land from surface water runoff is usually caused by intense rainfall that may only last a few hours. The resulting water follows natural valley lines, creating flow paths along roads and through and around developments and ponding in low spots, which often coincide with fluvial Floodplains in low lying areas.
• Groundwater Flooding: Groundwater flooding is caused by the emergence of water originating from underground when the water table rises to or above ground level and is particularly common in karstic landscapes. This can emerge from either point or diffuse locations. The occurrence of groundwater flooding is usually very local and unlike flooding from rivers and the sea, does not generally pose a significant risk to life due to the slow rate at which the water level rises. However, groundwater flooding can cause significant damage to property, especial in urban areas and pose further risks to the environment and ground stability. Groundwater flooding can persist over a number of weeks and even months. In most cases groundwater flooding cannot be easily managed nor lasting solutions engineered although the impact on buildings can be mitigated against through various measures.
• Flooding from Drainage Systems: Flooding from artificial drainage systems occurs when flow entering a system, such as an urban storm water drainage system, exceeds its discharge capacity, it becomes blocked or it cannot discharge due to a high water level in the receiving watercourse. Sewer flooding problems will often be associated with regularly occurring storm events during which sewers and associated infrastructure can become blocked or fail.
• Flooding from Reservoirs, Lakes and other Artificial Sources: Reservoirs can be a major source of flood risk. Whilst the probability of dam failure or breach occurring is very small, the consequences of such an event can be devastating thereby presenting a risk of flooding which has to be considered.
4.0 Addressing Flood Risk in the Tralee Municipal District Local Area Plan
4.1 Introduction
This section details the approach to Flood Risk Management adopted in the Tralee Municipal District Local Area Plan.
Tralee MD SFRA Page 20
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
4.2 Collation of Flood Risk Data
In 2015, as part of the review of its Local Area Plans, and in order to meet the needs of the Strategic Environmental Assessment process and the requirements of the Department of the Environment, Heritage and Local Government / Office of Public Works Guidelines, “The Planning System and Flood Risk Management” (2009), Kerry County Council undertook a county wide Strategic Flood Risk Assessment. The Council also conferred with OPW officials, the Lead Agency for Flood Risk Management in Ireland, in completing the county wide assessment of flood risks and in formulating the flood risk management strategy which informed the preparation of the Tralee Municipal District Local Area Plan. For the purposes of the assessment, information about flood risks was collated from a number of sources including but not limited to:
• Predictive and historic flood maps, and Benefiting Lands Maps, from the national flood hazard mapping website, http://www.floodmaps.ie; operated by the Office of Public Works (OPW), where information about past flood events is Recorded and made available to the public.
• Preliminary Predictive flood maps available, produced under the CFRAM Studies.
• OPW Preliminary Flood Risk Assessment indicative flood maps.
• Irish Coastal Protection Strategy Study (ICPSS).
• River Basin Management Plans and reports.
• Expert advice from OPW who may be able to provide reports containing the results of detailed modeling and flood-mapping studies, including critical drainage areas, and information on historic flood events, including flooding from all sources.
• National, regional and local spatial plans, such as the National Spatial Strategy (NSS), Regional Planning Guidelines (RPGs), Development Plans and Local Area Plans that provide key information on existing and potential future receptors.
This data was amalgamated into an indicative flood data map for the County, which is used as the basis for this SFRA. Further information that has become available in the intervening period from other flood studies, including the outputs from the National CFRAM Programme, (Catchment Flood Risk Assessment and Management) and the Irish Coastal Protection Strategy Study (ICPSS), undertaken by the OPW. The updated flood zone mapping provides information on the three main flood zones as follows: Zone A - High probability of flooding. Most types of development would be considered inappropriate in this zone. Development in this zone should be avoided and/or only considered in exceptional circumstances such as in major urban or town centres, or in the case of essential infrastructure that cannot be provided elsewhere. A Justification Test as set out in the Ministerial Guidelines must be applied in such cases. Only water-compatible development such as docks, marinas, dockside activities that require a waterside location, amenity open space, outdoor sports and recreation, would be appropriate in this zone. Zone B - Moderate probability of flooding.
Tralee MD SFRA Page 21
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
Highly vulnerable development such as hospitals, residential care homes, Garda, Fire and Ambulance stations, dwelling houses and primary strategic transport and utilities infrastructure would be generally considered inappropriate at this location unless the justification test can be met. Less vulnerable development such as retail, commercial and industrial uses, sites used for short term caravan and camping and secondary strategic transport and utilities, infrastructure and water compatible development might be considered appropriate in this zone. Less vulnerable development, such as retail, commercial and industrial uses, sites used for short term letting for caravans and camping and secondary strategic transport and utilities infrastructure should only be considered if adequate lands/sites are not available in Zone C and subject to a flood risk assessment to the appropriate level of detail to demonstrate that flood risk to/from the development can or will be managed adequately.
Zone C - Low probability of flooding. Localised flooding from sources other that rivers and the coast can still occur. Development in this zone is appropriate from a flood risk perspective, subject to assessment of flood hazard from sources other than rivers or tidal and would need to meet the normal range of proper planning and sustainable development considerations at the planning application stage. The maps are indicative in nature and are intended to primarily function as a screening tool. The areas at risk may be more or less extensive in practice than indicated in the flood mapping. The mapping may be refined where possible over time as other more detailed flood risk assessments are completed by the OPW.
Within areas not specifically identified by the plan as being at risk of fluvial or tidal flooding (i.e. within Zone C) a flood risk screening assessment may still be required to assess potential impact of development on adjoining Flood Zones A or B, particularly with respect to surface water management. An Assessment of the risk of other sources of flooding such as pluvial or ground water flooding may also be needed.
The inclusion of the flood zone information on the settlement maps of the Tralee Municipal District is the first step in managing flood risk in the future. The updated mapping provides for an improved understanding of flood risk issues within the Municipal District. The maps indicate the extent of flood zones that should be safeguarded from development and will support the application of the sequential approach, and the justification test as appropriate, in areas where development is proposed.
As part of the review of the Tralee Municipal District Local Area Plan, all zoned lands in areas at risk of flooding have been considered in the context of the updated indicative flood zone maps.
4.3 Flood Risk within the Tralee Municipal District
The Strategic Flood Risk Assessment provides an appraisal and assessment of available flood risk data for the land use plans contained within the boundaries of the Tralee Municipal District Local Area Plan. This process identifies flood risk indicators in each area and may also demonstrate a requirement for the gathering of additional information
Tralee MD SFRA Page 22
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
at specific locations where proposed zoning may be at significant risk of flooding and where a detailed flood risk assessment is therefore necessary.
Stage 1 SFRA (flood risk identification) was undertaken in order to identify whether there may be any flooding or surface water management issues within or adjacent to lands and consequently whether Stage 2 SFRA (initial flood risk assessment) should be proceeded to. The Stage 1 SFRA examines existing flooding information to identify flood risk within the Local Plan Area and was based on existing information on flood risk indicators based on historical evidence and computational models. Flood risk to each settlement has been appraised based on the indicative Flood Zones within the settlement boundary and is summarised in Table 4.1 below, Table 4.1 Flood Risk by Settlement in the Tralee Municipal District

4.4 Flood Risk Management Strategy
The assessment and management of flood risks in relation to planned future development is an important element of sustainable development. The majority of towns, villages and smaller settlements has either a river or a stream running through the built-up area or close by and are inevitably exposed to some degree of flood risk when those rivers or streams overflow their normal course. Similarly, in coastal areas, flooding can periodically occur following unusual weather or tidal events.
Generally, the purpose of zoning is to indicate to property owners and members of the public the types of development which the Planning Authority considers most appropriate in each land use category. Zoning is designed to reduce conflicting uses within areas, to protect resources and, in association with phasing, to ensure that land suitable for development is used to the best advantage of the community as a whole.
The approach adopted has generally been to:
• Include, on the settlement maps, information on the areas at risk of flooding (extent of Flood Zones A and B),
• Avoid development in areas at risk of flooding; and
• Where development in floodplains cannot be avoided, to take a sequential approach to flood risk management based on avoidance, reduction and mitigation of risk.
In response to local circumstances, particularly where there may be some uncertainties in relation to flood risk data or where land has been zoned in a previous plan or planning permission has already been granted, the approach has been modified and lands have been zoned for development with a requirement that a detailed site specific flood risk assessment be carried out at the project stage. A more detailed explanation of this is given in the next section.
4.5 The Approach to Zoning in Areas at Risk of flooding
Within the areas identified by the Indicative Flood Risk Mapping as being at risk (Zone A or B), all proposals for development will need to comply with the Ministerial Guidelines–‘The Planning System and Flood Risk Management. In this LAP, land use zoning objectives within the indicative Flood Risk Areas have been included in the plan where either:
• The land use zoning objective has been considered in the context of the “Development Plan Justification Test” set out in the Ministerial Guidelines;
• The zoning objective has been stemmed from a similar objective in the County Development Plan and is included in this Local Area Plan in order to facilitate the local verification of the indicative Flood Risk Maps at the project planning/planning application stage.
In the preparation of the Tralee Municipal District Local Area Plan and Variation to Tralee Town Development Plan 2009 - 2015 (as extended), proposed zonings were generally assessed relative to the provisions of the Guidelines and the Justification Test for Development Plans as detailed in the Guidelines. The Justification Test is generally
Tralee MD SFRA Page 25
Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
required in situations where the planning authority needs to consider future development in areas at a high or moderate risk of flooding, for uses or development vulnerable to flooding that would otherwise be inappropriate. In such circumstances, all of the following criteria must be satisfied:
a) The urban settlement is targeted for growth in the National Spatial Strategy, Regional Planning Guideline’s, or Statutory Plans defined under the provisions of the Planning and Development Act, 2000, as amended.
b) The zoning is required to achieve the proper planning and sustainable
development of an urban settlement and is
o Essential to facilitate the regeneration and/or expansion of the centre of the
urban settlement; o Comprises significant previously developed and/or under-utilised lands;
o Is within or adjoining the core of an established or designated urban settlement;
o Will be essential to achieving compact and sustainable urban growth; and
o There are no suitable alternative lands for the particular use in areas at lower
risk of flooding within or adjoining the core of the urban settlement.
c) A Flood Risk Assessment to the appropriate level of detail has been carried out as part of the SEA, which demonstrates that flood risk to the development can be adequately managed and the development will not cause adverse impacts elsewhere.
The approach taken in the Local Area Plan provides, for the detailed assessment of the extent of the actual flood risk relative to that indicated on the indicative mapping via a phased flood risk assessment procedure. The first stage of this assessment process provides a prospective developer with the opportunity to verify the Indicative Flood Zone Mapping in the first instance, and address any local ambiguities. Depending on the outcome of the verification stage, a prospective developer may then have the opportunity to demonstrate compliance with the requirements of the Development Plan Justification Test and carry out a detailed site specific assessment, as appropriate. This flood risk assessment process is set out in Chapter 10 of the County Development Plan 2015 – 2021. Development proposals on lands within areas at risk of flooding will also be subject to the “Development Management Justification Test”, details of which are set out in the Guidelines. The Table below lists the specific zoned sites within the Tralee Municipal District that are located within either Flood Zone A or B and the circumstances of their inclusion.

4.6 Approach to Development in Areas at Risk of Flooding
Where development is proposed within an area at risk of flooding, either on land that is subject to a specific zoning objective, lands within the “existing built up area” of a town or within a development boundary of a village, intending applicants need to comply with the provisions and objectives, as appropriate, of Chapter 10 of the Kerry County Development Plan 2015 – 2021, and with the provisions of the Ministerial Guidelines “The Planning System and Flood Risk Management”.
4.7 Flood Risk and Development Management
The following key requirements for the management of development in areas at risk of flooding shall be adhered to:
a) Minor proposals for development, for example small extensions to existing houses or changes of use, in areas at moderate to high risk of flooding should be assessed in accordance with Planning Guidelines: “The Planning System and Flood Risk Management”.
b) Where flood risk constitutes a significant environmental effect of a development
proposal, a sub-threshold EIS may be triggered. Screening for EIA should be an integral part of all planning applications in areas at risk of flooding.
c) Any proposal in an area at risk of flooding that is considered acceptable in
principle must demonstrate that appropriate mitigation measures can be put in place and that residual risks can be managed to acceptable levels. Addressing flood risk in the design of new development should consider the following:
• Locating development away from areas at risk of flooding, where possible.
• Substituting more vulnerable land uses with less vulnerable ones.

Tralee Municipal District Local Area Plan Strategic Flood Risk Assessment
• Identifying and protecting land required for current and future flood risk management, such as conveyance routes, flood storage areas and flood protection schemes etc.
• Addressing the need for effective emergency response planning for flood events in areas of new development.
d) Site layout, landscape planning and drainage of new developments must be
closely integrated to play an effective role in flood-reduction. As such, proposals should clearly indicate:
• The use of Sustainable Drainage Systems (SuDS) to manage surface water run-off.
• Water conveyancing routes free of barriers such as walls or buildings.
• Identifying floodplain areas to indicate the shared use of the land and to identify safe access routes.
e) To ensure that adequate measures are put in place to deal with residual risks,
proposals should demonstrate the use of flood-resistant construction measures that are aimed at preventing water from entering a building and that mitigate the damage floodwater causes to buildings. Alternatively, designs for flood resilient construction may be adopted where it can be demonstrated that entry of floodwater into buildings is preferable to limit damage caused by floodwater and allow relatively quick recovery. Such measures include the design and specification of internal building services and finishes. Further detail on flood resilience and flood resistance are included in the Technical Appendices of the Planning Guidelines, The Planning System and Flood Risk Management.
5.0 Managing Flood Risk in the Future
5.1 Achievement of the Local Area Plan
The inclusion of Indicative Flood Zone maps for the settlements of the Municipal District is the first step in managing flood risk in the future. The maps are primarily intended to function as a screening tool. They are not a substitute for detailed hydraulic modelling, such as may be required to assess the level of flood risk for a specific development. The flood maps should be used to guide decision making when determining whether a detailed Flood Risk Assessment is required for any given site. The maps are intended for guidance, and cannot provide details for individual properties.
5.2 Monitoring and Review
Information in relation to flood risk will be monitored and reviewed by the Council and the Flood Risk Assessment (FRA) will be updated as appropriate as new information becomes available. There are a number of key outputs from possible future studies and datasets which could inform any update of the FRA as availability allows. A list of
