Work has been going on behind the scenes for around a year to create a town-council-style body in St Helier.
Constable Simon Crowcroft says the aim is to devolve more powers from the States, enabling services to be agreed and delivered at local government level.
A previous proposal asking States Members to back such a move was rejected, but now new plans are gathering pace.
At tomorrow’s parish assembly, attendees are due to vote on whether to set up the shadow body, which would essentially serve as an extension of the current roads committee.
If approved, it will would run on a trial basis in 2020.
Mr Crowcroft explained: ‘At the moment the States won’t devolve powers to the parish, because who do they devolve them to? There isn’t a body; it is just the Constable. By setting up this body the parish can take on things like parking permits, that shouldn’t be taking up government time.
‘The planning has gone into this and setting up the shadow body is a way of building our case to take to the States.’
Members of the shadow council would be designated work under different portfolios but the body would be unable to pass laws.
Any decision to devolve certain powers to the parish would have to be agreed by the States Assembly.
‘For example, one member is working on a campaign regarding cigarette litter, and it will be about developing work like that,’ Mr Crowcroft said.
‘It is about taking powers from the States for work that can be done at a local government level.’
