Heatons worked closely with Aggregate Industries to prepare the planning application for a significant restoration project in Deep Dale, a cherished Peak District valley, to its former natural beauty after decades of quarry work.

The project will include the removal of approximately 150,000m³ of quarry waste, allowing the restoration of Topley Pike Quarry and the reinstatement of Deep Dale. Deep Dale was historically used as a mineral waste site during the 1970’s and 80’s, thousands of tonnes of quarry by-products were discarded there under old waste consent agreements.
Aggregate Industries and the Peak District National Park Authority have now agreed on a sustainable transfer and restoration plan. This plan prioritises water quality, slope stability, and the conservation of protected species while ensuring the valley’s full restoration.
The limestone valley of Deep Dale, renowned for its shallow soils, supports a rich diversity of wildflowers, making it a significant ecological area. In response to this unique environment, Heatons engaged technical environmental consultants to devise a comprehensive scheme aimed at restoring the valley’s natural state. This work will enable the ecological reinstatement of Deep Dale while also facilitating the restoration of Topley Pike Quarry. This initiative brings substantial landscape and biodiversity benefits to the Peak District National Park, further enhancing the area’s natural heritage.
Once the project is complete, the area will boast new or rejuvenated limestone grasslands, native broadleaf woodlands, and rocky ledges for nesting birds. Methods such as hydro-seeding, in partnership with Derbyshire Wildlife Trust, have already initiated the restoration process, setting the stage for a transformed and ecologically rich landscape.
As part of the longer-term plan, Topley Pike Quarry will be restored using the fine waste material that will be safely contained in engineered cells within the quarry void. This containment will ensure that the waste does not escape into nearby watercourses. By relocating the waste on-site, the project also avoids the need for off-site disposal, reducing both heavy vehicle movements and carbon emissions. Upon cessation of quarrying and restoration operations the quarry will be restored to a lake with areas of marginal habitat.
Both Deep Dale and the adjacent River Wye are designated as Sites of Special Scientific Interest (SSSI) due to their rich biodiversity. The surrounding area also holds European designations as a Special Area of Conservation (SAC), highlighting its ecological significance.
Spencer Warren, Managing Director at Heatons, commented: “Heatons was appointed for our expertise in handling large-scale planning applications. Our task was to develop a proposal that not only addressed the project’s scale and complexities, but also carefully considered the environmental sensitivities involved. With input from environmental experts throughout the process, we are delighted that this beautiful area in Deep Dale will be restored to its natural landform, bringing significant biodiversity benefits along the way.”
