It is recommended that a Flood Plan be drawn up for the site. This Flood Plan should<br />
detail appropriate action to take in a flood event and should include suitable evacuation<br />
procedures, safe egress route and a plan showing the locations of assembly point. The<br />
assembly point should be outside the floodplain, which is toward the east in the parish<br />
of West Winch.<br />
This is particularly important during the construction and decommissioning phase, as<br />
this is when most workers and personnel will be onsite. The Flood Plan should also be<br />
made available for maintenance staff during operational phase to ensure they<br />
understand the correct evacuation procedure during a flood event.<br />
10.6 Safety<br />
The SFRA Flood Hazard Zone (Figure 7) indicates that a small southern portion of the<br />
site is located within an area at risk of rapid inundation, if flood defences were to breach<br />
or overtop. It is advised that in the case of emergency, construction and maintenance<br />
workers should evacuate toward the north (beyond the IDB owned Puny Pumping<br />
Station), away from the south (i.e. Diary Farm), preferably toward the northeast in the<br />
parish of West Winch when safe and possible to do so. The safe egress route should<br />
be developed and included as part of the Flood Plan mentioned above.<br />
The risk of a defence breach is considered to be minimal as long as regular inspection<br />
and maintenance works are carried out appropriately.
