ASHEVILLE — A group of developers and planners is putting together plans for what would be one of the city’s largest new housing developments in recent years along Fairview Road in Oakley.

But instead of the mountainside sites that are drawing so much interest from developers in the region — and retirees moving to the area — the development would be located in an urban setting on 30 acres that’s now either graded and empty or occupied by two buildings, one industrial and one retail.
