5767 : IS - Coastal Geomorphology

Variable Measure Stop Readings Summary Target Pass/Fail
Evidence of negative impacts from adjacent activity Yes or No True, True, True, False Y
Target: The context and relationships of any geomorphological features of interest to the Dungeness SSSI should not be diminished through the use of the surrounding land in a way that leads to changes that might detrimentally affect the features of interest
Presence of engineering works Yes or No False, False, False, False N
Target: No new engineering obscuring or damaging the features of interest
Presence of tipping or landfill Yes or No False, False, False, False N
Target: No un-consented tipping or landfill obscuring or damaging the features of interest.
Presence of tree planting Yes or No False, False, False, False N
Target: No un-consented tree planting obscuring or damaging the remaining ridges.
