UD 1 Underground Development
- Residential basements and other underground development, including car parking and swimming pools, should have no significant adverse impact on:
- the viability of garden spaces. This requires maintaining 3 metres of depth for roots of large trees and 2 metres of depth for roots of medium trees. Large and medium trees are defined as:
- large trees (ultimate height of 15m+): a minimum of 30 m3
- medium trees (ultimate height of 8 -15m): a minimum of 20 m3;
- the character and verdant amenity of garden spaces, including through the impact of light wells, car lifts and other surface features;
- the viability of trees with ecological or amenity value and potential for future tree planting. This requires maintaining 3-metres of depth for roots of large trees and 2-metres of depth for roots of medium trees;
- underground streams or spring lines, including through cumulative impact, and
- neighbouring properties, though impacts, and cumulative impacts, on ground water and land stability.
- the viability of garden spaces. This requires maintaining 3 metres of depth for roots of large trees and 2 metres of depth for roots of medium trees. Large and medium trees are defined as:
- Development proposals that include new water features to manage drainage, including daylighting of underground rivers, will be encouraged;
- Development proposals should be accompanied by sufficient information to allow proper assessment of impacts, including how they:
- will not cause cumulative erosion of garden space; and
- will not contribute to localised groundwater flooding.
