PPS 15: Planning and Flood Risk
Flood Risk: Raising Awareness
3.1 While the scale of flood plain development in Northern Ireland is not comparable to that in England, there are a number of areas throughout the Region where development is at risk from flooding. Notably Strabane, Omagh, Castlederg and Newcastle have all suffered from river flooding in recent years. Estuarine flooding has occurred on the Roe at Limavady and on the Lagan at Belfast, while Portrush, Rostrevor and Newtownards have experienced coastal inundation. In addition, localised flood events caused by intense and/or prolonged rainfall and local conditions have been experienced across the Region with increasing frequency.
3.2 The SNIFFER Report (see paragraph 2.4) suggests that there is a generally low level of awareness among the population of Northern Ireland about the potential implications of climate change and increased flood risk. The Environment and Heritage Service Climate Change Indicators Report identifies 13 indicators intended to assist in monitoring how the Region's climate is changing and increase awareness of the effects of such change at a local level. This PPS aims to assist in improving public understanding about the risks of flooding and locating human activities in areas susceptible to flood risk by providing background information on the causes of flooding (see Annex A), the consequences of flooding and an explanation of the concept of flood risk (see Annex B). Information is also provided about the principles underpinning Sustainable Drainage systems (SuDs) and the potential these may offer in alleviating flood risk in the Region (see Annex C).
