1.1 Flood History River Flow Path (include review of Dromineer is situated on the banks of Lough Derg with the Floodmaps.ie) also located nearby. Minor tributaries to the Nenagh River and Lough Derg are located within the town’s boundary. Flood Event Records There are no records of flood events on floodmaps.ie for this location. PFRA database comments (in italics): 1.2 Relevant information on OPW comments flooding issues from Not designated APSR as failed to reach predictive analysis threshold or OPW and LA staff receive strong LA support. Suggested by LA for RR or Local Study Predictive < 150 - No / Minor History - No Strong LA Support as APSR RL - No properties damaged in 2009 event (which was exceptional) - However, LA concern - Include for Risk Review - Rosemarie Lawlor to inform Jacobs of inclusion as additional Risk Review site (then re-set APP_CODE_R2 = 0)

LA comments Car park and large area flooded in Nov 09. But no properties were damaged Risk Review?? Lake rising. Local study. Carpark floods but maintenance carried out in 2009 summer.

Meeting / discussion summary comments:

LA comments • The car park flooded in 2009. • Two abandoned properties at the car park may have flooded, both are potentially designated • Flooding did not really affect any properties

Summary Comments Car park overlooking Lough Derg flooded in 2009. There are potentially (if required) two nearby properties at risk of flooding, but the remainder of properties within Dromineer are situated on high ground. There are an insufficient number of critical receptors at significant risk of flooding to warrant designation as an APSR.
