Summary Comments The River Shannon in this locality has a long history of flooding. The PFRA mapping predicts a significant flood risk to Lanesborough Power Station and the surrounding road / infrastructure network. Lanesborough Power Station is confirmed as having sufficiently significant flood risk to warrant designation as an IRR following this desk based assessment. No site visit is warranted in accordance with Jacobs correspondence to OPW dated the 24
th August
2011 (email ref: 147/MH) as the site has a clear flood history, and the PFRA evaluation indicates that the site is at risk.
