Sometimes called tree protection zones, a tree preservation order (TPO) is an order made by a local planning authority in England to protect specific trees, groups of trees or woodlands – this includes the unseen roots.
Once TPO’s are enforced they are rarely removed and there are heavy fines if disregarded. Bellmoor Construction were faced with TPO on a 50 house build site.
We worked with them to navigate both tree roots and associated restrictions to plot an underground route that would carry surface water drainage to the allocated brook at a controlled rate. Horizontal directional drilling is ideal for this type of precision drilling, we installed 30m of 225mm drainage ducting avoiding the tree roots and adhering to the TPO rulings about having plant near trees.
We are seeing more and more tree preservation orders on sites and are happy to help contractors to complete jobs while complying with the local authority.
