Unit

Chyandour 20.3

Summary management approach

Continue to maintain defences as this is a transition area between the changeable Longrock-Eastern Green frontage and the fixed frontage of Penzance. The approach also protects the main road link into Penzance. This unit also needs to be considered as part of the larger Mounts Bay Strategy: refinement of the management approach may be required with significant managed realignment potentially required in the east.

Generic approach assigned to this unit

Management approaches depend on funding and relevant approvals and permissions. Adaptation to coastal change may be needed. If defences are present, some risk from flooding, erosion or ground instability may remain.

Time periods (short (0 to 20 years), medium (20 to 50 years) and long (50 to 100)) are approximate and do not signify precise dates of management transitions.
