Following a consultation exercise in 2018/ 2019, flood control international was contracted to design and supply flood barriers to protect the stations entrances. A fully removable stop log solution was selected, which did not disrupt access to the station nor have any visual downsides during normal operation, but which could be rapidly deployed when required in advance of a storm.
At a remote egress location, on the very end of the wharf, a stainless-steel flood door was also specified, as this area would be the first to be inundated with flood water.
Between august 2020 and march 2021, flood proofing infrastructure was added to the four entrances around the station. During extreme weather, the stations flooding status would be monitored, and additional aluminium planks installed when needed.
Stop logs were designed to fully surround the above ground headhouses of the station entrances; the distinctive glass and sloping steel structure would otherwise have required significant modification to accept the removable barriers just at the openings. The system was designed to use the absolute minimum number of separate components, and so almost all of the aluminium beams were the same
size and interchangeable. Similarly, the posts and other components were standardised. Thus ensuring, when needing to be deployed, no time or effort would be wasted in selecting incorrect components or incorrect beam lengths.
The receivers and blanking caps were selected to provide minimum visual intrusion, and to ensure that they would’nt become a trip hazard or cause problems when the area is being snow-ploughed.
A major benefit of the stop log system is that it can be deployed well in advance of any storm, with just the last few remaining spans being infilled immediately before the floodwaters arrive. This has been especially important, as the transit system needs to have free access and egress for the longest duration possible, and flood control internationals stop log system allows for that.
