3.5 - Policies and Objectives
The policies and objectives set out below accord with the overall objectives of national climate action policy, the Dublin City Council CCAP as well as the climate action principles set out in the NPF and RSES.
As climate action policy continues to develop with the publication of the Development Plan Guidelines for Planning Authorities June 2022 and annual updates to the National Climate Action Plan, Dublin City Council acknowledges that it may be necessary to adapt policies in future in order to ensure full compliance with any new legislative or policy requirements.
It is the Policy of Dublin City Council: |
|
CA1 |
National Climate Action PolicyTo support the implementation of national objectives on climate change including the ‘Climate Action Plan 2021: Securing Our Future’ (including any subsequent updates to or replacement thereof), the ‘National Adaptation Framework’ 2018 and the ‘National Energy and Climate Plan for Ireland 2021‑2030’ and other relevant policy and legislation. |
CA2 |
Mitigation and AdaptationTo prioritise and implement measures to address climate change by way of both effective mitigation and adaptation responses in accordance with available guidance and best practice. |
It is an Objective of Dublin City Council: |
|
CAO1 |
Dublin City Council Climate Change Action PlanTo implement Dublin City Council’s 2019 Climate Change Action Plan in consultation and partnership with stakeholders including the Dublin Metropolitan Climate Action Regional Office (CARO), Codema, residents and elected representatives. |
CAO2 |
Variation of Development Plan to Reflect New Guidance / LegislationTo consider a future variation(s) of the development plan, where required, to ensure consistency with the approach to climate action recommended in forthcoming ministerial guidelines, any other relevant guidelines and/or relevant legislation and government climate action policy. |
CAO3 |
Quantification of Greenhouse GasesTo support the Eastern and Midland Regional Assembly (EMRA) in identifying a robust method for quantifying the relative GHG impacts of alternative spatial planning policies as part of the European Union ESPON ‘QGasSP’ research programme. |
3.5.1 Sustainable Settlement Patterns
Settlement patterns, built form, mobility and the mix of land uses in the city will be key factors in transitioning to a low carbon city, as well as providing a range of other environmental, social, and economic benefits.
Planning the city such that people are enabled to live and work and access facilities by walking and cycling or through the provision of convenient public transport options (bus / rail) will reduce the need to travel by car and the associated carbon emissions. This aligns with the 15 minute city concept whereby people have the ability to access most of their daily needs within 15 minutes on foot or bicycle from where they live. It also aligns with the overall approach set out in the government’s Housing For All Plan (2021) which emphasises that compact growth contributes to a low carbon climate resilient society.
Chapter 2: Core Strategy sets out a sustainable settlement strategy for the city in which compact growth, including brownfield redevelopment and urban infill, is a priority in line with the National Planning Framework and the Regional Spatial and Economic Strategy.
Chapter 4: Shape and Structure of the City sets out a strategy which places a focus on the development of lands located within the existing footprint of the city, centred around convenient public transport options and developed to increased densities to prioritise sustainable low carbon movement and the creation of walkable mixed use neighbourhoods. This strategy is also reflected in Chapter 8: Sustainable Movement and Transport.
It is the Policy of Dublin City Council: |
|
CA3 |
Climate Resilient Settlement Patterns, Urban Forms and MobilityTo support the transition to a low carbon, climate resilient city by seeking sustainable settlement patterns, urban forms and mobility in accordance with the National Planning Framework 2018 and the Regional Spatial and Economic Strategy 2019. |
CA4 |
Improving Mobility Links in Existing Areas To support retrofitting of existing built-up areas with measures which will contribute to their meeting the objective of a low-carbon city, such as reopening closed walking and cycling links or providing new links between existing areas. |
CA5 |
Climate Mitigation and Adaptation in Strategic Growth Areas To ensure that all new development including in Strategic Development and Regeneration Areas integrate appropriate climate mitigation and adaptation measures. See also Section 15.4.3. Sustainability and Climate Action and Section 15.7.3 Climate Action and Energy Statement. |
Climate Mitigation Actions and the Built Environment
It is vital that the current and future form of the built environment will respond, and be resilient to the impacts of climate change.
As a result, there is a need for both new and existing development not only to mitigate against climate change, but also to adapt to such changes.
Chapter 15: Development Management contains comprehensive guidance regarding the standards and criteria by which development proposals for the city will be assessed. A central guiding principle of this chapter is to ensure that climate action forms an integral consideration in the development management process.
Climate Mitigation Actions and the Built Environment
With regard to climate mitigation actions, given that existing commercial and residential sectors accounted for approximately 70% of total carbon dioxide emissions for the Dublin City area according to the Dublin City Climate Action Plan, 2019, these sectors require targeted intervention in order to reduce their impact on climate change. The government’s Housing for All Plan will support the retrofit of 500,000 homes in Ireland by 2030 to a B2 Building Energy Rating (BER).
In line with this overall approach, proposals for major retrofitting of existing buildings should seek to reduce carbon dioxide emissions, improve the efficiency of resource use (such as water) and minimise the generation of pollution and waste from existing building stock. Such retrofitting projects should also seek to use innovative energy efficiency measures, such as decentralised and renewable energy in order to further reduce their carbon footprint. In this regard, some 9,000 DCC homes have already had energy upgrades as part of an ongoing energy upgrade programme.
Another key mitigation measure in relation to the built environment is to ensure that proposals for substantial demolition and reconstruction works can be justified having regard to the ‘embodied carbon’ of existing structures as well as the additional use of resources and energy arising from new construction relative to the reuse of existing structures.
Climate mitigation actions will also be required to be integrated into the building design, construction and operation of new development in the city.
In this regard, sustainable building design will include consideration of the building fabric, energy efficient services, energy generation and material resource conservation.
A key climate mitigation action which should be implemented into all new development relates to the need to reduce energy demand, to increase energy efficiency and to provide renewable energy on-site if possible.
In this respect, it will be important to have regard to the potential of waste heat and district heating in addressing the heating needs of new development in the city, particularly having regard to the ongoing development of the Dublin District Heating System (DDHS).
Climate Adaptation Actions and the Built Environment
With regard to climate adaptation actions and the built environment, both existing and future development should be resilient to climate change.
This will entail encouraging ‘soft measures’ such as promoting initiatives to encourage behaviour change and advising citizens of how to prepare for extreme weather events; ‘green measures’ which include green infrastructure and Sustainable Drainage Systems (SuDS), and finally, ‘grey measures’, namely infrastructure such as walls, embankments and attenuation tanks.
Climate Action Energy Statements
In order to ensure that all future development integrates the principles of energy efficiency in the built environment and the use of efficient and renewable sources of energy, all applications for significant new developments, or for significant refurbishment projects, shall be required to submit a Climate Action Energy Statement as part of any overall design statement for a proposed development (see Chapter 15, Section 15.7 for further detail).
This statement shall also provide outline information relating to the anticipated energy performance and CO2 emissions associated with the development as well as information outlining how the potential of district heating and other low carbon energy solutions have been considered in relation to the development.
Details as to the required contents of any such Climate Action Energy Statement is included in Chapter 15: Development Standards.
It is the Policy of Dublin City Council: |
|
CA6 |
Retrofitting and Reuse of Existing BuildingsTo promote and support the retrofitting and reuse of existing buildings rather than their demolition and reconstruction, where possible. See Section 15.7.1 Re-use of Existing Buildings in Chapter 15 Development Standards. |
CA7 |
Energy Efficiency in Existing BuildingsTo support high levels of energy conservation, energy efficiency and the use of renewable energy sources in existing buildings, including retro-fitting of appropriate energy efficiency measures in the existing building stock, and to actively retrofit Dublin Council housing stock to a B2 Building Energy Rating (BER) in line with the government’s Housing for All Plan retrofit targets for 2030. |
CA8 |
Climate Mitigation Actions in the Built EnvironmentTo require low carbon development in the city which will seek to reduce carbon dioxide emissions and which will meet the highest feasible environmental standards during construction and occupation, see Section 15.7.1 when dealing with development proposals. New development should generally demonstrate/ provide for:
|
CA9 |
Climate Adaptation Actions in the Built EnvironmentDevelopment proposals must demonstrate sustainable, climate adaptation, circular design principles for new buildings / services / site. The council will promote and support development which is resilient to climate change. This would include:
|
CA10 |
Climate Action Energy StatementsAll new developments involving 30 residential units and/or more than 1,000sq.m. of commercial floor space, or as otherwise required by the Planning Authority, will be required to submit a Climate Action Energy Statement as part of the overall Design Statement to demonstrate how low carbon energy and heating solutions, have been considered as part of the overall design and planning of the proposed development. |
3.5.3 Energy
The decarbonisation of the energy sector by shifting from fossil fuels to low- or zero-carbon energy sources is a key element of climate action policy. As stated in Chapter 9: Sustainable Environmental Infrastructure, this will require the energy sector to embrace a more diverse range of low, zero-carbon and renewable energy sources and to provide for secure, resilient, decarbonised and decentralised utilities.
In addition, area based initiatives, such as Decarbonising Zones, and initiatives aimed at changing how energy is produced and consumed, such as the SEAI’s Sustainable Energy Communities play an important role in transitioning towards low carbon energy solutions.
Renewable Energy
Renewable energy comes from natural sources that are continuously replenished by nature and is, therefore, a more sustainable alternative fossil fuels. Renewable energy sources include: wind energy, solar energy, water energy (hydro, wave and tidal energy), geothermal energy (from heat below the surface of the earth), ambient energy (from air) and biogas (anaerobic digestion).
The National Climate Action Plan includes a target to increase the share of electricity demand generated from renewable sources to up to 80% where achievable and cost effective, without compromising security of electricity supply. The plan outlines a number of measures to deliver this target including the decarbonisation of our energy systems, reinforcing and upgrading our grid, a new approach to electricity demand management, large scale investment in renewable energy generation, micro-generation and community-based projects, as well as other supporting measures.
In the spatial context of Dublin City, the principle renewable energy sources include solar power, micro-renewable energy and offshore wind energy. In addition, a potentially significant future source of low carbon energy for the city is geothermal energy.
Solar Energy
With regard to solar energy, there are a range of technologies available to exploit the benefits of the sun, including photovoltaic panels (PV), solar thermal panels, solar farms and solar energy storage facilities. Small to medium scale solar rooftop PV installations are suitable for urban areas, particularly large industrial roof spaces, where land availability is limited. Solar PV can be installed in new developments, or retrofitted on to existing buildings.
Wind Energy
It is envisaged that wind power will make the most significant contribution to the achievement of national targets for renewable electricity. Micro-renewable wind energy generation has a part to play in reaching these targets, and potential may exist for on-site and micro wind energy production in industrial areas and business parks subject to the requirement to protect residential amenity in surrounding areas. In residential areas of the city, micro-renewable wind energy generation is currently permissible under the provisions of the Planning and Development Regulations, 2001 (as amended).
Potential also exists for the production of electricity from large scale offshore wind energy facilities off the coast of Dublin City in the Irish Sea. In this regard, Dublin City supports the implementation of the ‘Offshore Renewable Energy Development Plan’ (OREDP) published in 2014 by the Department of Communications Energy and Natural Resources (and subsequently reviewed in 2018) and will co-operate with state and semi-state agencies in relation to the implementation of projects in the Irish Sea.
Where appropriate, Dublin City Council will also seek to facilitate infrastructure such as grid facilities on the land side of any renewable energy proposals of the offshore wind resource, in accordance with the principles of the National Marine Planning Framework.
Geothermal Energy
Geothermal energy is heat energy stored below the surface of the Earth which can be used for heating and/or to generate electricity.
To support its commitments under the National Climate Action Plan and the 2019 Programme for Government, the government carried out an “Assessment of Geothermal Resources for District Heating” and also prepared a “Roadmap for a Policy and Regulatory Framework for Geothermal Energy in Ireland”.
According to these documents, Ireland has a recognised potential for low-to-medium temperature geothermal energy resources (> 400 m deep) suitable for large-scale or district heating and cooling in municipal, residential and industrial areas.
To support the greater deployment of geothermal energy in Ireland, the government is developing a policy regulatory framework to facilitate the exploration for, and development of, geothermal energy resources.
Other Sources of Renewable Energy
In addition to the primary sources of renewable energy addressed above, other sources of renewable energy exist, which have the potential to contribute to the overall goal of decarbonising the energy sector. One such example relates to the extraction of energy and other resources from sewage sludge as referenced by the RSES (RPO10.13).
It is the Policy of Dublin City Council: |
|
CA11 |
Energy From Renewable SourcesTo support, encourage and facilitate the production of energy from renewable sources, such as from solar energy, hydro energy, wave/tidal energy, geothermal, wind energy, combined heat and power (CHP), heat energy distribution such as district heating/cooling systems, and any other renewable energy sources, subject to normal planning and environmental considerations. |
CA12 |
Micro-Renewable Energy ProductionTo support, encourage and facilitate the development of small scale wind renewable facilities / micro-renewable energy production. |
Offshore Wind-Energy ProductionTo support, encourage and facilitate the implementation of the 2014 ‘Offshore Renewable Energy Development Plan’ (OREDP) and any forthcoming review and to facilitate infrastructure such as grid facilities on the land side of any renewable energy proposals of the offshore wind resource, where appropriate and having regard to the principles set out in the National Marine Planning Framework. |
|
CA14 |
Geothermal EnergyTo support, encourage and facilitate the exploration for, and development of, geothermal energy resources having regard to emerging government policy on geothermal energy. |
District Heating and Waste Heat
District heating and waste heat recovery is a highly significant source of low carbon energy, and as set out in the RSES, in the form of projects such as the Dublin District Heat System will act as key enabling infrastructure for the city in the medium to long term.
District Heating networks typically use locally sourced heat energy, and distribute it to local homes and businesses, therefore, reducing Dublin’s reliance on imported energy and fuel. District heating utilises low carbon heat sources such as renewable energy and waste heat recovery, reducing Dublin’s CO2 emissions, while achieving energy efficiency and climate change mitigation.
The 2021 National Climate Action Plan is highly supportive of the development of district heating and includes a specific target to deliver up to 2.7 TWh of district heating, with the exact level to be informed by the outcome of a National Heat Study.
The Climate Action Plan includes specific actions relating to district heating including Action 183 "to ensure that national, regional and local planning frameworks encourage and facilitate the development of district heating where appropriate to facilitating compact urban development".
The Climate Action Plan refers to the ongoing work being carried out to inform the development of district heating policy, including the completion of the comprehensive assessment to support the rollout of district heating in Ireland. It also refers to two district heating projects in development, one of which is the Dublin District Heating System (DHS) centred at Poolbeg and the Docklands.
The main initial source of heat for this network is the Poolbeg waste to energy facility, which has the capacity to deliver 90 megawatts of heat, equivalent to the heating needs of 50,000 to 80,000 homes in the city.
The first phase of the DDHS was designed to serve the North Lotts and Grand Canal Strategic Development Zone (SDZ) and the Poolbeg West SDZ, as provided for in government policy.
Once the first phase of the DDHS is established, the next phase of its development would entail the imminent expansion of the network, firstly to areas directly adjacent to the SDZs which currently make up the Docklands Strategic Development and Regeneration Area (SDRA), and then on to the wider city through connections with existing, new, local and communally heated developments.
According to Codema, Dublin City has enough waste heat to provide for 1.75 times the total heating demand of the city’s buildings. Furthermore, Codema’s Spatial Energy Demand Analysis (SEDA), identified that over 75% of Dublin City areas have heat densities high enough to be considered feasible for connection to district heating systems.
In order to ensure the future development of District Heating in Dublin City, it will be necessary to ensure that significant new residential and commercial developments, particularly in SDRAs are ‘district heating enabled’, where feasible, in order to ensure that they are capable of being connected with local or citywide District Heating systems. Where this is not feasible, the proposed energy and heating solution should offer a similarly efficient and low carbon solution.
Details as to the requirements for specific SDRAs as well as details on the requirements a development must meet in order to be considered ‘district heating enabled’ is provided in Chapter 13: Strategic Development and Regeneration Areas and in Chapter 15: Development Standards.
It is the Policy of Dublin City Council: |
|
CA15 |
Waste Heat, District Heating and Decentralised EnergyTo actively encourage the development of low carbon and highly efficient district heating and decentralised energy systems across the city utilising low carbon heat sources such as renewable energy and waste heat recovery and to promote the connection of new developments to district heating networks where such systems exist/can be developed in a given area. |
CA16 |
The Dublin Disctrict Heating System (DDHS)To support, encourage and facilitate the development and expansion of any necessary energy infrastructure which will deliver the low carbon Docklands and Poolbeg catchment of the Dublin District Heating System (DDHS) project including, its pipeline infrastructure and its energy centre with energy storage and back-up heat production. |
CA17 |
Supporting the Potential of District Heating in Dublin CityTo support, encourage and facilitate the potential of district heating in Dublin City, all Climate Action Energy Statements submitted to the Council (see Policy CA10) shall include an assessment of the technical, environmental and economic feasibility of district or block heating or cooling, particularly where it is based entirely, or partially on energy from renewable and waste heat sources. In addition:
|
CA18 |
Capture and Utilisation of Waste HeatTo encourage proposed and existing developments and facilities (such as data centres) to capture and utilise otherwise wasted heat, and use waste heat either on-site, or in an adjoining, and nearby sites, in compliance with all relevant Energy Efficiency Regulations. |
Energy Initiatives, Strategic Energy Zones and Decarbonising Zones
A number of significant strategies and initiatives have been introduced (or are being prepared) in order to further drive the transition towards low carbon energy use across the city as a whole as well as in local communities.
Strategic Energy Zones
This ongoing work will also assist in the identification of potential ‘Strategic Energy Zones’ in accordance with Regional Policy Objective (RPO) 7.35 of the RSES which states that “EMRA shall, in conjunction with local authorities in the Region, identify Strategic Energy Zones as areas suitable for larger energy generating projects, the role of community and micro energy production in urban and rural settings and the potential for renewable energy within industrial areas”.
Local Initiatives
Public and stakeholder engagement is extremely important in addressing climate change and it is recognised that there is a need to foster and build momentum on wider citizen engagement in climate change, across all age groups.
A successful established example of community engagement in this regard is the SEAI’s Sustainable Energy Communities initiative, which assists groups of people come together to improve how energy is used for the benefit of their community with the common goals of using less energy, using clean, renewable energy and using smart energy.
Decarbonising Zones
Action 80 of the Climate Action Plan 2021 identified the need to engage at a local level and included a specific action which requires local authorities to identify and develop plans for at least one Decarbonising Zone (DZ) in their administrative area.
A Decarbonising Zone is a spatial area identified by the local authority, in which a range of climate mitigation measures can co-exist to address local low carbon energy, greenhouse gas emissions and climate needs.
Dublin City Council has identified Ringsend/Irishtown as a Decarbonising Zone and work is progressing in conjunction with Codema and CARO on an implementation plan to provide for the development demonstrator projects which will harnessing a range of energies technologies and initiatives.
Dublin Region Energy Masterplan
Codema has developed the Dublin Region Energy Master Plan. The plan provides evidence-based, and costed pathways for the Dublin region to achieve its carbon emission reduction targets to 2030 and 2050, building on the energy areas identified in the Spatial Energy Demand Analyses (SEDAs) for the four Dublin local authority areas.
It is the Policy of Dublin City Council: |
|
CA19 |
Decarbonising ZonesTo support, encourage and facilitate the specific polices and projects identified in the Decarbonisation Zone of Ringsend/Irishtown in order to address local low carbon energy, greenhouse gas emissions and climate needs and commit to establishing Decarbonising Zones in each LEA (Local Electoral Area) within the lifetime of this plan, with a view to designating all of Dublin City as a decarbonised zone by the end of this Development Plan. |
CA20 |
Strategic Energy ZonesTo support, encourage and facilitate the designation of potential Strategic Energy Zones in the Dublin City Area in conjunction with the Eastern and Midland Regional Authority. |
CA21 |
Sustainable Energy CommunitiesTo support, encourage and facilitate the ongoing efforts and future development of Sustainable Energy Communities in Dublin City through the SEAI ‘Sustainable Energy Communities’ Initiative. |
CA22 |
Dublin Region Energy MasterplanTo support, encourage and facilitate the preparation of the Dublin Region Energy Masterplan by Codema and to support its implementation in conjunction with neighbouring Dublin local authorities, Dublin Metropolitan CARO and other relevant stakeholders. |
3.5.4 Waste
Promoting the Circular Economy
Chapter 9: Sustainable Environmental Infrastructure as well as Chapter 15: Development Standards seek to integrate a more sustainable approach to waste based on circular economy principles.
National climate action policy emphasises the need to take action to address climate action across all sectors of society and the economy. In the waste sector, policy on climate action is focused on a shift towards a ‘circular economy’ encompassing three core principles: designing out waste and pollution; keeping products and material in use; and regenerating natural systems.
The government’s commitment to these principles is underlined by the Circular Economy and Miscellaneous Provisions Act 2022, which provides a national policy framework for Ireland’s transition to a circular economy.
It will also seek to implement many of the actions contained in the recently published Waste Action Plan for a Circular Economy which sets out Ireland’s National Waste Policy for 2020-2025.
Construction and Demolition Waste
In addition to setting out policy measures relating to issues including municipal waste, food waste and single use plastic, the Waste Action Plan addresses the issue of construction and demolition waste as it relates to the planning system.
The Waste Action Plan highlights the need to revise the 2006 Best Practice Guidelines on the Preparation of Waste Management Plans for Construction and Demolition Waste Projects, which culminated in the publication of the Best Practice Guidelines for the Preparation of Resource and Waste Management Plans for Construction and Demolition Projects 2021. The Waste Action Plan also outlines the intention to bring construction and demolition waste guidelines within the framework of statutory planning guidelines, to ensure that there is a consistent application of planning requirements.
It is the Policy of Dublin City Council: |
|
CA23 |
The Circular EconomyTo support the shift towards the circular economy approach as set out in a Waste Action Plan for a Circular Economy 2020 to 2025, Ireland’s National Waste Policy, as updated together with The Whole of Government Circular Economy Strategy 2022- 2023. https://www.gov.ie/en/publication/b542d-whole-of-government-circular-economy-strategy-2022-2023-living-more-using-less/ |
CA24 |
Waste Management Plans for Construction and Demolition ProjectsTo have regard to existing Best Practice Guidance on Waste Management Plans for Construction and Demolition Projects as well as any future updates to these guidelines in order to ensure the consistent application of planning requirements. |
3.5.5 Sustainable Transport
According to data collected by the SEAI, the transport sector was the single largest consumer of energy in Ireland, accounting for 40% of energy use in 2018. In terms of greenhouse gas emissions, data collected by the EPA indicates that the transport sector was responsible for 20.4% of total greenhouse gas emissions in 2019, second only to the agriculture sector. This data demonstrates the need not only to reduce transport by private vehicles, but also to reduce the direct emissions from vehicles themselves.
Chapter 8: Sustainable Movement and Transport sets out a strategy which responds to these challenges by seeking to minimise the need to travel and by promoting a shift from private car use towards more sustainable forms of transport (see Chapter 8, Section 8.5.6: Sustainable Modes). It also addresses the recent policy and technological developments relating to electric vehicles and alternative fuels which present an opportunity to significantly decarbonise transport across the city.
Decarbonising Transport and Electric Vehicles (EVs)
The 2021 National Climate Action Plan calls for the combination of measures to influence the spatial pattern of development, urban structure and overall mobility, with low carbon technology measures, such as a significant increase in the EV fleet.
The Plan sets out a government target to accelerate the take up of EV cars and vans so that by 2030, there will be 945,000 EVs and low emitting vehicles (LEVs) on the road.
In order to cater for this growth in electric vehicles, it will be necessary to ensure that sufficient charging points and rapid charging infrastructure are provided to appropriate design and siting considerations and having regard to the Planning and Development Regulations (2001) as amended, which have been updated to include EV vehicle charging point installation. Regard will be had to advances being made in EV charging technology as well as the development of new, efficient, innovative and accessible ways of providing charging points.
It is the Policy of Dublin City Council: |
|
CA25 |
Electric VehiclesTo ensure that sufficient charging points and rapid charging infrastructure are provided on existing streets and in new developments subject to appropriate design, siting and built heritage considerations and having regard to the Planning and Development Regulations (2001) as amended, which have been updated to include EV vehicle charging point installation. |
It is an Objective of Dublin City Council: |
|
CAO4 |
Regional Strategy for Electric Vehicle (EV) ChargingTo support and implement the forthcoming Regional Strategy for Electric Vehicle (EV) charging over the lifetime of the plan in order to facilitate the transition to low carbon vehicles required to achieve 2030 national targets. |
3.5.6 Flood Resilience and Water
With more extreme rainfall events anticipated with climate change Dublin is likely to experience increased flooding (pluvial, fluvial and coastal, groundwater and network) in vulnerable areas of the city. Climate change projections also show a shift in the seasonality of rainfall, with an increase in winter and a decrease in summer. Coupled with changes in temperature, these changes pose a threat to people, critical infrastructure including water supply and security, ecology and property.
The Floods Directive calls for member states to undertake strategic flood risk assessments and to identify flood risk management measures. The Office of Public Works (OPW) has prepared flood maps for future climate scenarios and Flood Risk Management Plans outlining measures such as flood alleviation schemes / flood defence works (grey infrastructure) to manage flood risk within the relevant river catchments.
Green Infrastructure (GI) as part of Sustainable Drainage System (SuDS), also has a role to play in reducing flood risk and in integrated water resource management. GI reduces the rate and volume of water entering the drains by intercepting it, providing temporary and permanent storage areas, and allowing water to infiltrate into the ground rather than being directed to drains. In addition, green infrastructure can filter out pollutants and sediments from over-land surface run-off and it can be designed to capture and store rainwater for reuse / conservation.
Establishing space for rivers corridors also plays a role in adaptation responses to achieve flood resilience. Protecting existing river corridors and landscaping and providing natural flood management measures such as the creation of wetlands within river corridors can help to manage river flooding by reducing the volume of runoff, by promoting water infiltration into the soil and slowing runoff to streams, and by delaying the downstream passage of flood flows.
The development plan has been subject to, and is accompanied by a Strategic Flood Risk Assessment (SFRA), prepared in accordance with the Guidelines for Planning Authorities (DEHLG and OPW, 2009). Consequently, this plan zones appropriate sites for development and identifies how flood risk can be reduced.
Chapter 9: Sustainable Environmental Infrastructure and Flood Risk sets out a River Corridor policy approach for the city’s rivers. It also contains policies and objectives on SuDS (see also Appendix 12); Green Roofs (see also Appendix 11); Surface Water Management Plans (see also Appendix 13) and policies and objectives on the separation of foul and surface water drainage systems, water conservation and coastal zone management.
It is the Policy of Dublin City Council: |
|
CA26 |
Flood and Water Resource ResilienceTo support, encourage and facilitate the delivery of soft, green and grey adaptation measures to enhance flood and water resource resilience in the city and support the delivery of grey adaptation measures to enhance flood and water resource resilience where necessary. |
CA27 |
Flood Risk Assessment and AdaptationTo address flood risk at strategic level through the process of Strategic Flood Risk Assessment, and through improvements to the city’s flood defences. |
CA28 |
Natural Flood Risk MitigationTo encourage the use natural flood risk mitigation or nature based solutions including integrated wetlands, green infrastructure, and Sustainable Drainage Systems (SuDS) as part of wider adaptation and mitigation responses to achieve flood resilience. |
3.5.7 Green Infrastructure and Nature Based Solutions
Green Infrastructure (GI) can assist the city to adapt and become resilient to the effects of climate change while also playing a role in climate mitigation. The city’s GI features include natural and semi-natural features (the marine environment, parks, woodland, waterbodies, etc.) and nature based infrastructure (such as green roofs, tree pits, rain gardens and green walls).
These natural assets and urban greening elements provide a range of functions and benefits (ecosystem services) that contribute towards climate change adaptation and mitigation. The city’s trees, vegetation and soil capture and store carbon and provide evaporative cooling and shading in the city, mitigating the urban heat island effect.
Increasing, restoring and connecting habitats rich in biodiversity that provide valuable ecosystem services, is essential to increasing the city’s resilience to climate change and improving quality of life.
The provision of allotments and community gardens provide for food production which can contribute to reducing food miles and the provision of networks for sustainable travel modes such as cycle routes enables active travel thereby helping to reduce carbon emissions from transport.
Chapter 10: Green Infrastructure and Recreation sets out adaptive green infrastructure and urban greening policies and objectives to help implement climate action in the city. The forthcoming Dublin City GI Strategy will support new climate change actions as will the Dublin City Biodiversity Action Plan (2021-2025).
It is the Policy of Dublin City Council: |
|
CA29 |
Climate Action and Green InfrastructureTo protect, connect and expand the city’s Green Infrastructure while optimising the climate change adaptation and mitigation services it provides. |
CA30 |
Coastal Zone ManagementTo support, encourage and facilitate coastal zone management measures for adapting to climate change which include restoration of degraded ecosystems, increased flood resilience, water quality improvement, habitat conservation and provision of amenities for the residents and visitors of Dublin City. |
