Collision Detection
Y20
building @ Y20
1.2m overlap
Canopy (4.0m radius) + 3m setback encroaches 1.2m into building at year 20
gas @ Y30
0.8m overlap
Root zone (5.5m) encroaches 0.8m into gas 1.5m exclusion zone at year 30
Recommendations
Consider smaller species or one with narrow/upright form
Install root barrier on service side
Regular crown pruning may be required
