This month marks the beginning of a multi-million dollar project to upgrade Bangor's sea defenses.
In the lower Hirael area of the city, it is meant to safeguard more than 190 properties.
The project, which should be completed in about 10 months, has received positive press.
The Local Democracy Reporting Service claims that flooding has plagued the formerly prosperous fishing community for years.
Gwynedd Council and the Welsh Government, who are each contributing 85% of the project's £4.3m cost, are financing it.
The River Adda flood risk was reduced through engineering work that was finished in 2008, but it is still a danger.
According to current climate change predictions for sea level rise, tidal flooding is now the main risk to Hirael, according to project managers YGC.
Julie James, the minister for the Welsh government's response to climate change, stated: "Coastal communities must adapt to rising sea levels, and this scheme will help do just that. ".
Rising sea levels are a serious issue for coastal regions like Gwynedd, according to Berwyn Parry Jones of the Gwynedd Council, who also issued a warning that the work might be noisy and disruptive.
