A firm has submitted plans to fill an old quarry near Walcote and convert it into a woodland and wildlife site.
Site Cycle UK wants to put 104,000 cubic metres of soil in the 9.8 acres quarry off Gilmorton Road, before planting grass and trees.
Its application toHarborough District Council states it would fill the quarry within about three years before creating an area of trees and meadows.
Sand and gravel was excavated fromt he quarry but it has not been worked since the early part of th elast century.
The site lies within what was once the medieval village of Poultney, with artefacts having previously been found to the north, west and south of the quarry.
It has been used in recent years for motorcross.
But a planning application to use it as a permanent circuit was refused by the council and stop notices on such use have been issued in recent years.
Site Cycle proposes infilling would take place between 8am and 4pm, Monday to Friday.
It estimates there would be 78 lorry movements a day, with a wheelwash on site to avoid getting mud on surrounding roads.
The application states: “The final restoration scheme will deliver an enhanced matrix of habitats through woodland planting.
“The restored site will provide improved ecological connectivity with existing habitats beyond the bounds of the site by creating new wildlife corridors.”
