The measure would protect to the 1% AEP fluvial flood event, with an average hard defence height of 0.9m (reaching a maximum height of 1.8m). A detailed geotechnical structural and stability assessment of the existing embankments was not undertaken as part of the CFRAM study, but should be undertaken as part of the project-level assessment in progressing this measure. The Benefited land layer identifies land that was drained as part of the Drainage District. The low benefit-cost ratio is due to the relatively low risk to properties during the 1% AEP fluvial flood event in Trim, resulting in a small benefit value. 1,620 Sq. The Scheme, which comprises of the construction of an overflow weir to divert flow to the Broadmeadow River and the improvement of channel and culvert capacity along channel C1/7 of the Broadmeadow and Ward Scheme, is expected to provide protection against a 100-Year flood (1% Annual Exceedance Probability) for 69 properties against flooding from channel C1/7 of the Broadmeadow and Ward Scheme. These hard defences would protect to the 1% AEP flood event with an estimated average height of 1.3m and a total length of 0.58km.

The proposed measure consists of the installation of a sluice gate under the N25 to prevent the natural propagation of tidal water into low lying lands to the north of the N25 and is expected to provide protection against a 200-Year flood (0.5% Annual Exceedance Probability). This interim scheme has been complemented by a more comprehensive scheme, which has been substantially completed, to provide a higher standard of protection and protect more properties in the town. This option includes ongoing maintenance of the river walls, pumping stations and enhanced maintenance above the current Arterial Drainage maintenance programme for the full length of culverts on the Knockanelo through the town centre and the Flood Relief Culvert.

The OPW will work with the Environment Protection Agency, Local Authorities and other agencies during the project-level assessments of physical works and more broadly at a catchment-level to identify any measures, such as natural water retention measures (such as restoration of wetlands and woodlands), that can have benefits for Water Framework Directive, flood risk management and biodiversity objectives. Two weirs would be removed on the Nuenna River (02WEIR02 at Chainage 1227 and 03WEIR01 and Chainage 1240). These improved conveyance methods would provide protection from the 1% AEP fluvial event and involve removing approximately 338m3 of sediment from within the channel and upgrading the culvert to a 2.1m x 1m box culvert.
