APPENDICE 5
ENVIRONMENTAL REPORT
The following approach may be helpful for identifying the potential cumulative effects of the NAPs across the SEA issues/topics:
SEA topic | Part of NAPs / Alternative ( e.g. policy 1-8) | Potential cumulative impact of NAPs |
|---|
Speed | Night Time restrictions | Road Traffic Calming | Noise Barriers | Road Surfacing | Road Traffic Management | Aircraft | Train Wagons |
|---|
Improve human health | v | v | v | v | v | v | v | v | v |
Protect, maintain and where appropriate, enhance biodiversity. | - | - | - | X | - | - | - | - | X |
Protect, maintain and where appropriate, enhance landscape & townscape character. | v | v | X | X | v | v | v | v | v |
Protect, maintain and enhance air quality | v / X | X | - | - | - | v / X | - | - | v / X |
Reduce Greenhouse gas emissions. | v | - | - | - | - | v / X | - | - | v / X |
Interrelationship | v | v | v / X | X | v | v / X | v | v | v / X |
Cumulative effects on SEA topic can be identified by 'reading across' ? |
In the example above, each part of the NAP has a positive overall impact (reading 'down') except for quiet traffic calming and noise barriers, but the policies cumulatively have a significant positive effect on improving human health and protect, maintain and, where appropriate, enhance landscape & townscape character (reading 'across'). Where policies have negative effects, it is good practice to review to see whether they cannot be changed so as to reduce their joint effect. Negative and positive effects should not be assumed to cancel each other out.
v = positive, X = negative and - = neutral effect
