Garden centres in Lincolnshire who currently use brown tourism signs to attract customers to their coffee shops may have to remove them, says the county council.
Under draft guidelines, garden centres are no longer eligible and cannot be encompassed by the term 'tourist destination'.
The council argues that it wants to 'control the number of signs and street furniture and improve the visual environment'.
The proposals say that establishments such as garden centres, retail parks and shopping centres may be excluded from the definition.
However, in some instances, tea rooms within garden centres will be considered for signing although this must be reflected in their advertising.
A Lincolnshire County Council spokesperson told diyweek.net the proposals have yet to be adopted and are subject to agreement by a number of bodies: the Conservative group meeting, a Highways Policy development group meeting and an executive councillor.
It is anticipated a decision will be made before the end of the year.
