Glossary of Terms

Appropriate Assessment A required deliverable of the CFRAM study, an Appropriate Assessment (AA) identifies and addresses any potential impacts the flood risk management options and each of the FRMPs might have on areas designated as Natura 2000 sites. This includes Special Areas of Conservation (SACs) and Special Protection Areas (SPAs) and any associated candidate sites. The requirement for AA comes from the EU Birds Directive (79/409/EC) and the habitats Directive (92/43/EC).
AFA Area for Further Assessment

Areas of land where the degree of existing or potential risk is more significant than others in the study area. AFAs include existing towns and villages (which can be defined as CARs), areas for which significant development is anticipated and other areas or structures where existing or future flood risk is deemed significant.
CAR Community at Risk

Communities at Risk are existing urban or developed areas within an Area of Potential Significant Risk (AFA) with a significant flood risk from river or coastal sources. This includes any housing, industry, retail, amenity and recreational area. Communities at Risk vary in size from small communities such as Dromcolliher or Castleconnell, to larger conurbations such as Limerick or Ennis.
CFRAM Study Catchment-based Flood Risk Assessment and Management Study

The five year study covering the whole River Shannon catchment area which gives a picture of past flooding and areas at risk of future flooding, and suggests options for reducing and managing flood risk through FRMPs.
Communications and Engagement Plan The Communications and Engagement Plan establishes communications objectives and key messages; understands the social, economical, political and legislative context of the CFRAM study; identifies stakeholders; and sets out the approach, programme and methodology for engaging stakeholders and the public. It is a ?live? document that evolves over the course of the study.
DACD Defence Asset Condition Database

This database records the results of the Defence Asset Condition Survey which is carried out on all flood defence assets within AFAs, those along MPWs and in coastal areas. The survey involves the identification, inspection, photographing and assessment of all flood asset defences and entry of all relevant data in the DACD.
Flood Maps A range of Flood Maps are being produced for those areas where flooding may occur for the AFAs for each source of flooding. These include: ? Flood Extent Maps ? showing the extent of flooding, levels of confidence associated with the extents and areas benefiting from protection from flood defences. ? Flood Zone Maps ? showing three flood extent levels associated with Planning System and Flood Risk Management guidelines. ? Flood Depth Maps ? showing flood water depths ? Flood Velocity Maps ? showing velocities of floodplain flow ? Flood Hazard Maps ? showing a function of flood hazard (the ?risk to life?) calculated from flood depth, velocity and sometimes debris.
Flood Risk Review The Flood Risk Review is a review of the initial preliminary flood risk assessment carried out by the OPW based on readily available information to identify CARs and IRRs deemed to be at potentially significant risk. Through site visits, data collection, review of survey outputs, defence asset condition survey, review of spatial planning documents, and interviews with OPW staff and other stakeholders, alterations or additions to the CARs and IRRs identified during the preliminary flood risk assessment are considered as appropriate.
FRMP Flood Risk Management Plan

The plan produced for each UoM that sets out how OPW, stakeholders and local people should work together to take actions that address specific local flood risks.
HPW High Priority Watercourses

Watercourses that could give rise to existing or potential future fluvial or estuarine flooding within an AFA.
Hydraulics Reports Hydraulics Reports are technical documents produced for each UoM setting out work and analysis undertaken in relation to all surveys, digital modelling results, the defence asset condition database, and flood maps.
IRR Individual Risk Receptor

Individual properties or infrastructure assets (such as transport networks or utility services) outside of AFAs that, if flooded, would give rise to significant detrimental impact or damage.
MPW Medium Priority Watercourses

Watercourses that could give rise to existing or potential future fluvial and estuarine flooding within certain other areas within the Study Area.
OPW The Office of Public Works

OPW is the lead agency for flood risk management in Ireland. The coordination and implementation of the Government's policy on the management of flood risk in Ireland, in conjunction with their responsibilities under the Arterial Drainage Acts (1945-1995) form one of their four core services. In addition to flood risk management, their other areas of service include buildings and architecture, heritage and procurement.
Preliminary Options Reports Preliminary Options Reports are technical documents produced for each UoM setting out work and analysis undertaken in relation to the identification of viable actions and measures (agreed preferred options) to meet the flood risk management objectives. The Reports include the SEA Options Appraisal Report, Habitats Directive Screening Assessment, digital hydraulic modelling outputs, and flood maps.
RBD River Basin District

River Basin Districts are natural geographical and hydrological units for water management, as defined by the WFD. River basins are used instead of administrative or political boundaries. The Shannon RBD covers more than 18,000km2, includes the natural drainage basin of the River Shannon and covers 18 local authority areas (17 County Councils and 1 City Council). The Shannon CFRAM study area is the same area of land as the Shannon RBD.
SEA Strategic Environmental Assessment

The process by which environmental considerations are required to be fully integrated into the preparation of the FRMPs and prior to their adoption.
UoM Unit of Management

As the Shannon CFRAM study area comprises a River Basin District as defined under the WFD, it is divided into Units of Management, each of which constitute major catchments or river basins (typically greater than 1,000 km2) and their associated coastal areas, or conglomerations of smaller river basins and their associated coastal areas. There are five UoM within the Shannon CFRAM Study area, each of which will have its own flood maps, FRMP and actions for reducing and managing flood risk.
WFD Water Framework Directive

A single piece of framework legislation addressing increased demand by communities and environmental organisations for cleaner rivers, lakes, beaches and groundwater. The WFD defines River Basin Districts for water management.
