Developers at both the Infirmary Road development by the old North Road Hospital and the proposed flats behind the old Boars Head in Queens Road have cut several metres into the cliffs behind.
In the case of Infirmary Road deep fissures have now formed in the land at the top of the cliff, the Parc Natur Penglais owned by Ceredigion Council (pictured). An urgent survey has shown that rock six metres down remains solid but the cliff top is unsafe and substantial remedial work will be necessary.
In Queens Road there is, as yet, no similar evidence of subsidence but diggers have cut back to within two metres of the foundations of houses above and the risk is clear.
The problems highlight the need for greater scrutiny of large developments by Ceredigion Council.
