The decision to erect poles isn't made based on aesthetics to gardens .... it will be made based on cost, council permits (Section 58), TM, disruption ..... every situation is bespoke.
We have to give a 28-day notice informing of our intent to erect a pole (via a stake in the ground with the notice attached), and folk can, and do, contest it sometimes. I absolutely understand the aesthetics side though, as do our survey officers. They have to play the hand they're dealt with though, and if it is subsequently decided by the locals that the pole/s are unwanted, then a 2nd look at a possible re-plan may occur, but this doesn't usually yield other options.
We don't use the 'moles' for garden work atm, but may in time ?? But, the PTD form does state that the contractor will reinstate to the same standard found, or better. In this day and age of camera phones, there is always a 'before & after' proof of work.
