"Canal Hazard Zones" have beengenerated for areas which could flood if the Leeds and Liverpool canal were to overtopor breach. These hazard zones should influence the spatial placement ofdevelopment during the Sequential Test and highlight the need for FRA to investigatethe residual risk further during a site-specific FRA.
