Climate Impact Profile<br />
North West Flood August 2017<br />
One of the most significant recent events over the<br />
last 15 years occurred during August 2017 when 60-<br />
70mm of rain (63% of August rainfall) fell in 9 hours.<br />
This severe rainfall event resulted in flooding in the<br />
following local rivers:<br />
• River Faughan estimated total peak flow 5.4<br />
meters<br />
• Muff River total peak flow height 3.1 meters<br />
• Burndennet River total peak flow height 6.5<br />
meters<br />
This resulted in extensive flooding across the<br />
local area with homes, businesses, agriculture,<br />
infrastructure, services, heritage <strong>and</strong> biodiversity<br />
adversely affected. The estimated costs to the<br />
Department for Infrastructure is in excess of £12<br />
million. Approximately £36,000 was incurred<br />
directly by Council on a range of emergency costs<br />
(e.g. emergency householder payments, waste<br />
disposal costs <strong>and</strong> clean-up <strong>and</strong> community centre<br />
opening costs). In addition a significant amount of<br />
staff time as well as a further £350,000 on capital<br />
repair costs to Council assets <strong>and</strong> facilities was<br />
incurred.<br />
