1.0 Introduction to the Strategic Flood Risk Assessment

1.1 Introduction Kerry County Council has prepared the Draft Killarney Municipal District Local Area

Plan/Fourth Variation to the Killarney Town Development Plan 2009-2015 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 Killarney Municipal District.

This Strategic Flood Risk Assessment (SFRA) of the Draft Killarney Municipal District Local Area Plan/Fourth Variation to the Killarney Town Development Plan 2009-2015 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/Fourth Variation to the Killarney Town Development Plan

2009-2015 and 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) 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. As part of this a number of recommendations for SEA monitoring are provided within this SFRA.

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 Killarney Municipal District Draft Local Area Plan/Fourth Variation to the Killarney Town Development Plan 2009-2015. The report should be read in conjunction with the Local Area Plan/Fourth

Variation to the Killarney Town Development Plan 2009-2015, and the associated maps.

Killarney MD SFRA



The primary purpose of the SFRA is to determine flood risk within a particular

geographical area, in this instance, the Killarney Municipal District and to support spatial planning 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.

It should be noted the SFRA is an ever evolving document, which is to be reviewed and updated on a regular basis in the light of emerging information, flood data and

an improved understanding of flood risk. 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 Killarney Municipal District Local Area Plan/Fourth Variation to the Killarney Town Development Plan 2009-2015. 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 Killarney 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 Killarney Municipal

District, identifying the settlement hierarchy and the key population and household growth targets for the respective categories of settlement with the settlement

hierarchy. 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 Killarney 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,

Killarney MD SFRA



• 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:

• 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

Killarney MD SFRA



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);

• 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.

Killarney MD SFRA



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, 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).

Killarney MD SFRA



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

• 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 Killarney 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 Killarney.

• One Regional Town comprising of Castleisland.

• Five District towns comprising of Barraduff, Farranfore, Fieries, Kilcummin and Rathmore.

• Three Villages comprising of Fossa, Gneeveguilla and Scartaglin.

• Two Small Villages comprising of Cordal and Currow.

• Four Development Nodes comprising of Ballyhar, Currans, Faha/Listry and Glenflesk.

The Killarney 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. The findings of the RFRA have been

reviewed, and have informed the County SFRA.

2.2 Population and Household Growth The Killarney Municipal District covers an area of approx 89,360 Ha and has an existing

population of 39,935 people according to the 2016 Census. The Kerry County Development Plan 2015 – 2021 provides for a growth in population of 2,525 persons

corresponding to an allocation of 972 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 685 new houses proposed in

Killarney, 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 Killarney Municipal District is located within a designated site of nature conservation importance, while the majority of any remaining areas would

be located upstream of such sites. 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 Killarney Municipal District are detailed

in the table below.

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 Killarney Municipal District include; a karst spring at Tobermaing, Castleisland; a warm spring at Gneeveguillia, Rathmore; varied mineralogy at Ross Island; caves with

karren at Lough Leane; Muckross; Torc waterfall at Muckross, Killarney, Devonian sandstone and volcanics at lough Guitane; Aretes in the MacGuillycuddy’s Reeks,

channels at Barry’s Glen, Killarney and patermoster lakes at Killarney Lakes. 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.

Killarney MD SFRA



3.0 Identifying Flood Risk in the Killarney 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 Killarney 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 Killarney Municipal District with flood events attributed to fluvial sources ranging from Dennagh River to smaller tributaries and

drains.

Killarney MD SFRA



3.3 Rivers in the Killarney Municipal District The River Maine forms in Tobermaing and flows through Castleisland and continues to

flow westwards joining with the Glanshearoon Stream at the downstream of Castleisland and its tributary the Little Maine River and the before flowing south-westwards to Currans

Bridge. The River Shanowen rises near Mount Eagle and flows westwards towards

Castleisland where it joins with the Anglore Stream to form the River Maine at Castleisland. Castleisland is at risk of fluvial flooding from the River Maine and its

tributaries, the Shanowen, the Anglore and the Glenshearoon.

The River Flesk forms between Loo Bridge an N22 Bridge with the confluence of the Loo River and the Clydagh River and runs parallel with and north of the N22. Glenflesk is

located along the River Flesk and is at risk of fluvial flooding. The River discharges into Lough Leane at Killarney, which is also located along the River Flesk. There are a

number of other smaller rivers and tributaries which flow through Killarney into Lough Leane. Killarney is at risk of fluvial flooding.

The River Deenagh rises in Toremore and flows along the North of Killarney before

turning southwards along Port Road, and then westwards through the Killarney National Park to outfall into Lough Leane. Kilcummin is drained mainly by the River Deenagh and

is at risk of fluvial flooding. The River Blackwater rises near Glenatripple in the Mullaghareirk Mountains and flows

southwards to Rathmore before flowing in an easterly direction through County Cork.

The River Glanooragh flows in a northwest to south-easterly direction close to the small

rural village of Ballyhar.

3.4 Historical Flood Events Recent significant flood events have included:

Flood Event of 24th January 2014

Flooding has been observed in Castleisland on 24th January 2014, since the completion of the hydrological analysis and agreement of the calibration events. Photographs have been used to validate the areas that are vulnerable to flooding as a common sense check

and the 5%AEP to 2%AEP modelled flood extent correspond well with photographs of overtopping along the Glenshearoon into the Crag Cave, flooding at Glebe House Bridge,

Tullig and around Church Street. The prolonged period of rainfall also resulted in surface water flooding/ponding of agricultural lands/public roads in the townlands of Meanus/Camp, situated to the northwest of the town centre. However, the CFRAMS

model does not consider surface water flooding therefore the modelled outlines do not indicate flooding at this location.

Flood Event of 15th January 2011 Intense rainfall over a few hours caused river levels in the River Flesk to rise and flood

the adjoining floodplain in Killarney and Killarney National Park. However, flooding was restricted to open fields and recreation grounds next to the river and no properties in the

southern side of Killarney were affected.

Killarney MD SFRA



Flood Event of 19th November 2009 After a month of prolonged rainfall, over 80mm of rain fell within 48 hours, flooding parts

of Killarney along the River Deenagh as well the River Flesk. The saturated antecedent conditions meant that Lough Leane levels were already high prior to the event and

significant inflows from the other rivers entering the lake. The intense rainfall on the 19th November 2011 further raised levels which caused significant flooding to the Killarney National Park area, parts of the N70 and the local road network. The tourist area around

Muckross and the Lake Hotel were extensively flooded to depths of over 0.5m in some areas. This was the first recorded flooding of the Lake Hotel in the past 190 years.

Flood Event of 4th October 2008 Flooding at Tullig, Castlemaine resulted from a complex interaction of river flooding and

subterranean flow paths. Initially, river levels in the Glanshearoon River overtopped the left bank whereupon the flood water entered the Crag Cave complex to flood areas

downstream on the Anglore Stream. Several properties were flooded along Anglore Stream at Cordal Road. An additional commercial property was also affected by the flooding. However, interviews with local residents indicated that the River Maine was in

bank through the town.

Flood Event of 4th January 2008

Anecdotal reports of flooding suggest that heavy rainfall on the 4th January 2008 caused water levels to rise and spill out of Ballyoughtrough Stream along Old Station Road due

to potentially undersized culverts under access bridges along this reach. Additional flooding was also experienced around the N70 Bridge on Ashullish Stream where water bypassed the bridge, possibly due to siltation reducing the capacity of this reach.

Flood Event of 1st February 2002

A combination of high tidal level on the River Maine and flood flows on the adjoining tributary downstream of Castlemaine caused river levels to overtop the raised embankments and flood the surrounding farmland at Castlemaine. Fields were flooded

for several days, and the flood waters were unable to return to the river because the floodplain is below the embankments.

Flood Event of 17th February 1997 Similar to the 2011 event, intense rainfall caused the River Flesk levels to rise and flood

the adjoining floodplain in Killarney and Killarney National Park. However no properties were affected. High flows were recorded downstream at Laune Bridge but no flooding issues were reported on the River Laune.

Flood Event of August 1986 An intense summer rainfall event on 5th and 6th August 1986 resulted in a rapid rise in the River Flesk levels causing flooding of the recreational grounds along the River Flesk

in Killarney, but no properties were reported as being affected.

Flood Event of November 1980 The November 1980 event was the largest flow on record at Flesk Bridge. There was over 90mm of rain over 48 hours on the 1st and 2nd November 1980 causing Lough

Leane levels to rise and limiting discharge of the prolonged fluvial flood along the River Flesk. There was no gauge data for this event at White Bridge on the River Deenagh.

However, it is likely that the flood on the Deenagh was a similar %AEP to the River Flesk

Killarney MD SFRA



as the rainfall amount is between the catchments. The River Flesk levels spilled out-of-bank to flood Killarney National Park as well as fields and recreational grounds adjacent

to the river in Killarney. The River Deenagh was also reported as flooding but no precise locations were provided. However, no properties were reported as being affected.

There was also flooding upstream along the N22 between Loo Bridge and Glenflesk by the River Loo and River Flesk as reported by Kerry County Council which resulted in the

flooding of 23 houses, 3009 acres, the loss of 209 livestock, and 322 road access disruptions.

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 Killarney 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 Killarney Municipal District

Local Area Plan

4.1 Introduction

This section details the approach to Flood Risk Management adopted in the Killarney Municipal District Local Area Plan.

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 Killarney 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.

• 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), undertaken

by the OPW has been undertaken. 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.

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.

Extracts from the flood zone map, where relevant, informed the settlement maps included in the Local Area Plan. 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 Killarney

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 Killarney 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.

Killarney MD SFRA



4.3 Flood Risk within the Killarney 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 Killarney 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 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,

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 have 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 Killarney Municipal District Local Area Plan/Fourth Variation to the Killarney Town Development Plan 2009-2015, 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

Killarney MD SFRA



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 Killarney 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.

Killarney MD SFRA



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.

• 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.

• The signing of 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 detai led 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

Killarney MD SFRA



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

potential sources of information which will inform an FRA review is provided in Table 5.1 below.
