He said: "There are a number of hurdles yet to be overcome.
"If they give us a lease option for five years, that is not giving us planning permission.
"We are ready to go to cabinet with our plan. We have to make this happen for the right reasons and show we have the credibility of delivery."
He said any council creating a new Local Plan has to take account of their local football club's needs and a planning inspector would need evidence that the club had been considered.
Mr Fenty said any harm caused in the delivery of the scheme will be "significantly outweighed by the overwhelming good emanating from securing the future of GTFC plc."
He said: "It will leave a lasting legacy, deliver a flagship project, the first for generations. It would also secure the vast array of community schemes currently being delivered by Grimsby Town Sports and Education Trust, the club's delivery arm, all of which are as as much risk as the club itself, should this scheme not come to fruition." Following a visit to the proposed site, Grimsby MP Austin Mitchell said: "John Fenty has convinced me it is the only scheme which is viable.
"I have seen him make six to eight attempts to put it on the docks, on The Willows and Great Coates. But this is the most viable. "The difficulties can be removed. With a superstore or housing, it can finance a new ground. There could be other facilities such as skateboarding. It will provide a good centre. "The arguments about traffic congestion with people going to and from funerals and the traffic for Oasis Academy Wintringham can be overcome. It would be like uncorking the bottle if there was a roundabout that would enable people to get in and out easily." Mr Mitchell added: "I am happy. This has potential for development and is something the council should approve.
"He said the club and Grimsby "deserved it." Mr Mitchell said: "Grimsby has until now not yet had the chance that has been secured by Scunthorpe and other clubs to build a new ground." Company secretary for Lincolnshire Football Association Ltd, John Griffin, said: "The project is pivotal to the wider regeneration of the Greater Grimsby area and the prosperity of the businesses, communities, visitors and families supported by the club. "The football club facilities provide a vehicle to engage local people, promote healthy living and participation in sport and create new investment and jobs in the town. We believe that these benefits could not be realised without a new stadium given the constraints on the club's existing location and condition of its facilities."
David Boddy, assistant general manager of The Football Conference Ltd, said: "The club's contribution to the local community is also valued by our organisation. Through 'Football In The Community' and 'Study Support' programmes the club gives opportunities to hard to reach young people to develop their skills, ambitions and employability, many of whom progress into formal education, training or work."Manager at Hull and Humber Chamber of Commerce, Anne Tate added: "The new stadium facilities will give a much needed boost to the local economy by enabling the club to become more financially secure and grow the range of services it offers and by increasing opportunities for additional leisure-related investments, tourism spend and businesses, benefiting from procurement opportunities."
Grimsby Town Away Travel Club's spokeswoman Moira Tabois said: "As we have travelled to many different grounds over the years it has become apparent how important new grounds and their state of the art facilities can be to a club, its fans and surrounding area, particularly when there are facilities that can be used extensively for the wider community." Other supporters include Lord Haskins, on behalf of The Humber Local Enterprise partnership, the principal and chief executive of Grimsby Institute, Sue Middlehurst, Tony Bramley chief executive of Shoreline, Stagecoach and second-generation former town player Jim Fell.
