Jerry, if the site permits, why not show your locals the guidance on direct 
displacement then regard the matter as out of your hands?

You'll be familiar with the terms 'guerrilla gardening' and 'seed bombing', 
and I understand that some beavers were also 'bombed'. After COP26 there 
seems to be a greater awareness of the need for direct action so perhaps 
'tree bombing' is a practice whose time has come.

Thanks Mike and Jim - Pretty much as I assumed; but my question was 
whether there are are there any regulations or official guidance, 
specifically with regard to cables and other conduits that are not 
readily prone to disruption by root growth.

(Background: a local group wants to improve tree cover by planting on 
verges and open spaces but it is routinely refused permission by the 
company holding the 'public realm' management contract, on the grounds 
of there being 'services' present. So far there has been great 
reluctance to disclose what services are present where, but apart from 
access to the underground service maps, what's needed is some basic 
information on what they can or can't reasonably refuse.
The suspicion is that they just don't want more trees that they might 
have to take responsibility for...)

It depends on the trench spec for the services, but based on the mature 
size of the tree the potential distortion of cables is unlikely to cause 
problems, most pipes are robust (check for cast iron!), but glazed 
earthenware with clay-sealed joints can be at risk.
It just requires research with the services companies.

Are there regulations (or guidance) for lateral clearances required (or
advised) for tree planting over or near underground electric cables?
NJUG discusses the depth at which services should be set but it is
largely guidance for installing services near trees, not planting trees
near services.
Is there any reason or justification for prohibiting planting in a wide
verge because there are a couple of cables?
(I take for granted that precautions need to be taken to avoid direct
damage to cable, although I'm only talking about hand planting - no
mini-diggers or tree spades involved.)
