    Coastal erosion planning and funding failures: risk lessons for UK asset engineers

    A House of Commons committee warns that accelerating coastal erosion is putting UK transport corridors, utilities and other critical national infrastructure at growing risk, with some assets already within metres of receding cliff lines and undefended shorelines. MPs found current planning rules and fragmented funding streams delay or block schemes such as realignment of coastal roads, relocation of wastewater treatment works and reinforcement of rail embankments. The inquiry calls for a national coastal adaptation strategy, clearer responsibilities between the Environment Agency and local authorities, and long-term funding to prioritise defence, managed retreat or asset abandonment.
