The costs of disruption and evacuation of a Nursing Home need to be costed in partnership with the nursing home operators and Mayo County Council emergency planners. The Scheme, that comprises mainly of tidal Flood Defences walls and upstream storage in a retention basin upstream of the town, in addition to pump stations, localised defences and repair works to the existing channel banks, to provide protection against a 100-Year flood (1.0% Annual Exceedance Probability) for fluvial and a 200-Year flood (0.5% Annual Exceedance Probability) for tidal for 296 properties against flooding from either fluvial flooding, tidal flooding or both. extent mapping only takes into account coastal flooding from a combination of tide levels and storm surges; any Construction of 1,555m of new flood defence walls and 1,215m of new flood embankment. A 125m length of road would also have to be raised. The allowance for GIA varies around the coastline and The solutions described above provide an estimated 100-year flood protection (1% AEP) to over 100 houses in these areas from the critical one hour to three-hour thunderstorm flood events. A number of maps were produced for each tile to identify the extent and depth of flooding and the risk arising from flooding. An allowance of -0.5mm/year for GIA was included for the southern part of the national coastline only (Dublin to Galway and south of this). The Lower Morrell (Straffan) Flood Relief Scheme was initiated in 2010 following major flooding in 2009. The Scheme will provide protection for approximately 80 properties against for 1% Annual Exceedance Probability flood event from the Clare River and Turlough areas at Carnmore / Cashla and Lakeview and which comprises of the following: The proposed measure would include the placement of quay defence walls in order to protect against the 0.5% AEP design event with an average wall height of 1.2m, as required for public safety. The purpose of the schemes was to create land for agriculture. In addition to this Scheme, further developer led flood relief measures were completed along the watercourse. The hard defences would protect to the 1% AEP fluvial flood event, with an average height of 1.1m (reaching a maximum height of 1.5m) and a total length of 4km. Rainfall flooding is referred to as Pluvial flooding in the Maps and Plans. Low Probability flood events have an indicative 1-in-a-200 chance (Dublin) or 1-in-a-1000 (Raphoe, Co. Donegal) of occurring or being exceeded in any given year. The Present Day scenario is referred to as the Current Scenario in the Maps and Plans. Surveys to collect high resolution LiDAR data (circa 16 points/m2). Layer Information The result is a reduced flow along the Carysfort Maretimo reducing the length and height of any hard defences required.
