Significance
Major, adverse
Where the proposed change would materially and adversely affect or change the environment in a situation where there is a high sensitivity to change. The proposed change would
form a major and immediately apparent part of a valued view or would adversely affect and change the character and quality of a highly sensitive townscape or would adversely affect
an aspect of the setting of a highly valued designated heritage asset that contributes to its special character.
Moderate, adverse
Where the proposed change would materially and adversely affect or change the environment in a situation where there is some sensitivity to change. Where the proposed change
would form a recognisable new element within the scene that would cause a noticeable deterioration in the view or would adversely affect and change the character and quality of a
sensitive townscape or would adversely affect an aspect of the setting of a designated heritage asset that contributes to its special character.
Minor, adverse
Where the proposed change would have a limited impact on an environment where there is some sensitivity to change. Where the proposed change would form a minor component of
the wider scene that would cause a slight deterioration in the view that might be missed by a casual observer or would cause a slight adversely affect and change the character and
quality of a townscape or would have a slight adverse impact an aspect of the setting of a designated heritage asset that contributes to its special character.
Negligible
A magnitude of change that has little impact on an environment that has the ability to accommodate change. Where the proposed change would be imperceptible to a casual observer in
a view or would cause an imperceptible change to the setting of a townscape or would have an imperceptible impact on the aspects of setting of a designated heritage asset that
contribute to its special character.
No impact
Where the proposed development would have no impact on the view or townscape character or heritage setting.
Minor, beneficial
Where the proposed change would have a limited impact on an environment where there is some sensitivity to change. Where the proposed change would form a minor component of
the wider scene that would slightly enhance the view or would cause a slight improvement to the character and quality of the townscape or would slightly enhance an aspect of the
setting of a designated heritage asset that contributes to its special character.
Moderate, beneficial
Where the proposed change would materially and positively affect or change the environment in a situation where there is some sensitivity to change. Where the proposed change
would form a recognisable new element within the scene that would noticeably enhance the quality and character of the existing view or would improve the character and quality of a
townscape area or would materially enhance an aspect of the setting of a designated heritage asset that contributes to its special character.
Major, beneficial
Where the proposed change would materially and positively affect or change the environment in a situation where there is a high sensitivity to change. The proposed change would
greatly improve and enhance the quality and character of a valued view through the removal of visually detracting or discordant features or would improve the character and quality of
a highly sensitive townscape or would adversely affect an aspect of the setting of a highly valued designated heritage asset that contributes to its special character.
