  2. ‘CFRAM’ STUDIES • ‘CFRAM’ PROGRAMME • Outcome of National Flood Policy Review, 2004 • Compatible with FD Requirements, 2007 • Flood Maps • FRMPs • Pilot Studies: • Lee, Dodder, Fingal – East Meath: 2005-2011 • National Programme: 2011-2018 • Focused on 300 Communities (‘AFAs’)

  3. 300 ‘AFAs’

  4. SCOPE OF WORK • Survey & Data Collection • Appx. 6,500kms River Channel • Hydrology • Incl. Use of FSU • Hydraulic Modelling • 1D-2D Dynamically Linked Models • Flood Mapping • Extent, Depth, Velocity, ‘Risk-to-People’, Flood Zone & Various Risk Maps

  5. ‘CFRAM’ STUDIES • FLOOD MAPS (‘CFRAM’ PROGRAMME) • Range of Flood Maps Produced • Extent, Depth, Velocity, ‘Risk-to-Life’, Flood Zone & Various Risk Maps • Up to 8 Flood Event Probabilities • Future Scenario Mapping • 2 Representative Climate Futures • MRFS: +500mm MSL, +20% Qp • HEFS: +1000mm MSL, +30% Qp

  6. FLOOD MAPS • Detailed Mapping for 300 Communities • Incl. 90 Coastal Communities • Communities with Appx. 3m People (Appx. 2/3rds Population) • Less Detailed Mapping for Appx. 2,500 km Other River • Inform: • Sustainable Planning • Emergency Response Planning • Community Resilience

  7. ‘CFRAM’ STUDIES • FRMPs – COMMUNITY-LEVEL MEASURES

  8. ‘CFRAM’ STUDIES • FRMPs – COMMUNITY-LEVEL MEASURES • Screening & Option Development • Options Developed to ‘Line-&-Level’ & Costed • Appraisal • Multi-Criteria Analysis (MCA) • Cost-Benefit Analysis (CBA) • SEA / AA Environmental Assessment • Adaptability to Climate Change • Public Consultation: Over 450 PCDs

  9. ‘CFRAM’ STUDIES • FRMPs – COMMUNITY-LEVEL MEASURES • Overall FRS Programme (Protection) • 43 Schemes Completed • 35 Schemes in Construction, Design, Planning • 118 Further Schemes Proposed in FRMPs • Protection for Appx. 33,000 Properties: • Appx. 95% Properties at Risk in AFAs • Appx. 80% Properties at Risk Nationally

  10. ‘CFRAM’ STUDIES • FRMPs – NATIONWIDE MEASURES • Prevention: • Sustainable Planning & Devt. Management • Sustainable Planning Critical for Sustainable FRM • Guidelines: The Planning System and Flood Risk Management (OPW/DECLG, 2009) • Supported by OPW Advice & Flood Mapping

  11. ‘CFRAM’ STUDIES • FRMPs – NATIONWIDE MEASURES • Prevention: • Sustainable Planning & Devt. Management • Sustainable Planning Critical for Sustainable FRM • Guidelines: The Planning System and Flood Risk Management (OPW/DECLG, 2009) • Supported by OPW Advice & Flood Mapping • Consider Local Changes and Site-Specific FRAs

  12. ‘CFRAM’ STUDIES • FRMPs – NATIONWIDE MEASURES • Prevention: • Sustainable Planning & Devt. Management • Sustainable Urban Drainage Systems • Voluntary Home Relocation Scheme • Climate Change Adaptation Planning • Natural Water Retention Measures (ICM)

  13. ‘CFRAM’ STUDIES • FRMPs – NATIONWIDE MEASURES • Preparedness & Resilience: • Flood Forecasting & Warning • National Flood Forecasting Centre • Emergency Response Planning • Promotion of Individual / Community Resilience • Individual Property Protection • Flood Event Data Collection

  14. FLOOD RISK MANAGEMENT PLANS • Finalised 3rd May 2018 • Published: www.floodinfo.ie

  15. FUTURE WORK • CAPITAL FLOOD RELIEF PRPOGRAMME • Government Commitment • Budgets Allocation of Circa €1bn (NDP 2018-2027) • Annual Budget to Increase to €100m/yr • 10 Schemes in Construction, 25 in Design / Planning • Almost 120 Additional Schemes – FRMPs • Prioritisation – Appx. 50 ‘Tranche 1’ Schemes • Progressing to Project-Level Assessment • Generally Local Authority Lead; Part X

  16. FUTURE WORK • ADAPTATION TO CLIMATE CHANGE • The ‘CFRAM’ Programme • Future Scenario Flood Mapping / Risk Assessment • Assessment of Adaptability of Options • National Future Scenario Flood Mapping • Adaptation in Flood Relief Schemes • Adaptability of Past Flood Relief Schemes • Apply Managed Adaptive Approach • Scheme Adaptation Plans • Update Sectoral Adaptation Plan: Sept. 2019

  17. FUTURE WORK • NATURAL WATER RETENTION MEASURES • Emerging Approach often Promoted • Detailed Assessment at Project Scale • Concerns / Issues to Address: • Difficulty in Quantifying Projected Benefits • Effectiveness in Large Events • Intensive Land Owner Engagement • Benefits to Other Sectors: Integrated Catchment Mgt. • Research / Pilot Projects

  18. FUTURE WORK • PREVENTION AND PREPAREDNESS • Flood Forecasting and Warning • National Flood Forecasting Service in Development • Emergency Response & Community Resilience • Review of Emergency Response Plans, Informed by CFRAM Maps • Enhance Community Resilience • Property Resilience • Home Relocation Scheme • Pilot ‘IPP’ Schemes

  19. FUTURE WORK • SECOND CYCLE OF FLOODS DIRECTIVE • Review of PFRA, Flood Maps, FRMPs • Review, Not a ‘Re-Do’ • Opportunities for Refinement / Improvement • Consideration of Climate Change • Scope (AFAs): 1st Cycle • Relatively Low Threshold of Risk (Recent Floods) • Comprehensive Coverage of Communities • 2nd Cycle • No Need to Replicate CFRAM Programme • Focus on Understanding Risk in Rural Areas

  20. FUTURE WORK • SECOND CYCLE OF FLOODS DIRECTIVE • Sources: • New National, Indicative Fluvial Mapping • Review Extreme Coastal Levels • Groundwater / Turlough Mapping • Risk from Urban-Storm Water Systems / Artifical Water-Bearing Infrastructure • Impacts: • Understanding Rural Risk • Critical Infrastructure • Impacts of Climate Change

  21. FUTURE WORK • SECOND CYCLE OF FLOODS DIRECTIVE • PFRA: • Historic Flood Information (Floods 2012-Date) • Predictive Assessment of Risk (Incl. CFRAM Data) • Local and Expert Knowledge • Flood Maps: • Ongoing Changes (Infrastructure, Floods) • Need to Reflect Changes in Timely Manner • Flood Risk Management Plans: • Review of Progress on 1st Cycle FRMP Measures • Additional / Amended Measures

  22. SUMMARY • CFRAM – EVOLUNTIONARY STEP FORWARD: • Assessment Covering 3m People (2/3rds National Population) • 2nd Cycle: Review, Refine and Improve • PROTECTION: • >150 Schemes In-Hand / Proposed in FRMPs • Broadening Approach: NWRM / ICM • Ensuring Adaptability to Future Climate • PREVENTION & PREPAREDNESS: • Sustainable Planning & Development • National Flood Forecasting Centre • Community Resilience
