DarthKermit:. I might dig a trench and install conduit for a future UFB connection before I go ripping up any grass.
might pay to look at your Council for how deep that has to be
Q: For underground deployment, will trenches be dug to traditional depths or may newer “shallow trenching” techniques be used?
A: Again, this will depend on the local District Plan. New standards relating to fibre deployment are currently in consultation with Councils, utilities and others and will eventually form part of the Utilities Code. These provide guidance on how shallow trenching techniques may be used where this complies with the local District Plan.
that is most like on the street side, but i think there also something on the owner side for min depth for unities etc.
