Bradford will get its own waterfront under radical plans to regenerate the city centre.
The plans focus on the area around City Hall
The masterplan, commissioned by the city's urban regeneration company, has been designed by a firm of architects.
Unveiled on Wednesday by Lord Mayor Councillor Alan Hillary, it centres on an urban park around a new lake in front of the City Hall.
Bradford Centre Regeneration chief executive Maud Marshall said: "This is a once-in-a-lifetime opportunity to put to an end decades of decline.
"We believe it will help to regenerate Bradford's core, stimulating wealth creation and employment opportunities."
The park could include a drive-in cinema, outdoor swimming pool, city school, conference centre or place of worship.
The vision of Bradford's future, which would take 15 years to develop, also includes residential redevelopment of the Canal Road area to create a new canalside community.
And the Bradford Beck would be exposed in a bid to rejuvenate the Thornton Road corridor, with features including a wetland area and children's play areas.
Bradford Metropolitan District Council leader Councillor Margaret Eaton said: "This is an opportunity for the people of Bradford to choose the way they want the city centre to develop."
Residents can view an exhibition of the planned developments at the former Dillon's bookshop site on Market Street.
