Transforming a Closed Landfill into Sustainable Greenspace

Stone Pit 1, Dartford, Kent

Dartford Borough in North Kent has in the past been characterised by its historical association with the quarrying of chalk and other minerals on a massive scale, and a subsequent legacy of derelict and damaged sites which for decades blighted the area environmentally, economically and socially. One of the last big sites left in need of a productive future, a 40ha landfilled former Blue Circle chalk pit, is now being restored by Land Logical in partnership with the local community. Within five years, the site will have been transformed into a public amenity space with recreational facilities and improved biodiversity.

Key to unlocking this potential was negotiating purchase of the site and the securing of permission to restore the site into a sustainable landform using 0.5 million cubic metres of inert engineering materials and soils, and engagement with the local authorities – County, District and Parish – and environmental charity Groundwork, for whom an endowment is being provided as the precursor to taking on responsibility for managing the site on completion. The first stage of a three phase restoration scheme was commenced in May 2015.

A particular challenge on bringing this derelict site back into beneficial use has been undertaking the complete renewal of the sites’ gas management system.
