Coastal Risk: Expected losses (of lives, persons injured, property damaged, economic activity disrupted and
environmental degradation) due to a particular
natural (e.g., a storm) or human-induced (e.g., an oil spill) hazard for a given area and reference period. Hazard:
A threatening event (e.g., a coast flood; a pollution event from shipping of hazardous materials)
or an on-going process (e.g., wave action moving sand along a coast; excess fertiliser runoff from agricultural lands), or the probability of occurrence

Policy options • retreat – hold the line – realignment – no action
‘Working with natural processes’ • Soft protection measures

10 Planning for the soft coast
• Louisburgh is a rural village (pop. 314)
• 1km from the coast • To double in size by 2022 • Local economy
• small factory, some agricultural, commercial and retail activity, village’s inhabitants commute out of the area to work
• Holiday homes during summer months
• Tourism central to future development
• No major flood or erosion problems

14 Planning for the soft coast
A coastal land planner’s dilemma Scenario 1 – Do not include land in local area plan (red boundary on map) • Proposed as a NHA - a degree of protection from development
• Consolidate development around core of town • Does not assure retention of protection
Scenario 2 – Include land in the local area plan (blue boundary) • Recognise the role of the dune system and marsh in protecting Louisburgh
• Zone lands accordingly
HOWEVER - a danger that the area could be zoned inappropriately as the final decision made by elected representatives
• May be subjected to pressures from vested interests to have lands zoned for development.

Panning for the soft coast Greater awareness Implement existing policy • ANCORIM Tools
• Educational guides • Natural infrastructures and soft protection handbook • Website and databases • Good practice guide for decision makers
