Bath Recreation Ground Trust has decided to support the latest survey into Bath Rugby Club's plans to build a new £15m stadium on Bath Rec.
The trust also agreed to provide financial support for legal research
At a meeting on Friday, the trustees agreed to accept the findings of an independent public consultation which showed clear support for the plans.
The council-appointed trustees also agreed to extend the east stand's temporary seating lease by one year.
These changes are subject to the backing of the Charity Commission.
Bath Rugby needs to expand its capacity to meet the demands of the rugby union game's authorities.
The rugby ground on Bath Rec currently holds 9,000 spectators. The club wants to expand this to 15,000.
In order for the club to gain planning permission, the trustees of the Bath Rec site have to be satisfied that the public support the plans, that it is legal and that it is financially viable.
During 2006, the trustees of The Rec, acting on the advice of officers of Bath and North East Somerset Council, undertook a strategic review of the future of The Rec which included commissioning BDOR Limited to carry out a public consultation.
The results found 41.44% supported Bath Rugby's plan of redeveloping the ground where it is on the site.
Another 22.94% agreed with Bath Sport, an independent supporters' association, which put forward the option of moving the ground across the Rec to become part of a bigger sport and leisure complex.
The survey found 9.62% of respondents wanted the site returned to a green space and 26% did not want any of the options available.
The trustees also gave backing to the next stage of financially supporting legal research into the plans.
