Collapse feature remediation at 4 & 6 Green Field, off Pole Lane, Darwen

Summary of planning committee decision

Decided by Blackburn Planning and Highways Committee on 19 Feb 2026.

10/25/1307Approved

What was proposed

The proposal would remediate an unrecorded collapse feature by grouting its void and capping it with hardstanding.

“Proposed Development: Remediate the unrecorded collapse feature to the front of 4 and 6 Green Field…”

Officer report

The site

The site lies within a partly built housing estate and includes the front gardens and driveway of 4 and 6 Green Field.

“The application site forms part of a partially built-out housing estate, which is located within the settlement of Darwen and the Pole Lane North Housing Development Land Allocation (H064). The site staggers the front gardens/driveway of 4 and 6 Green Field, with the majority being within the…”

“Classified as Official\Anyone boundary of 6 Green Field. Neighbouring dwellings surround to 2 sides with open/highways land positioned to the north and west.”

Officer report

The recommended approach

Approval was recommended because the works were considered technically satisfactory, with land stability and contamination risks controlled through conditions.

“On balance, the proposals would be satisfactory from a technical point of view, with all issues having been addressed through the application process, or capable of being controlled or mitigated through appropriately worded planning conditions.”

“Land stability ➢ Land contamination and ground gas…”

Officer report

Residents’ concerns

Residents questioned the feature’s description, the application area, the technical information and possible structural effects on neighbouring properties.

“The submitted application form only states 4 Green Field as the site address yet works are also proposed at 6 Green Field. ➢ The submission documents incorrectly make reference to the fact that the collapse feature is a shaft. ➢ The submitted technical reports do not detail the professional credentials of the author.”

“Secondly, the planning application remediation plan document clearly shows the working area for remediation to cover a substantial part of our property, yet the application form only mentions work to be carried out at 6 Green Field, this also needs to be amended to both properties.”

Officer report

The committee decision

The committee approved the application subject to conditions and revised the wording of the validation condition.

“That the planning application be approved subject to the conditions highlighted in the Directors report and the revised wording of the following condition:”

“Following implementation of the remediation works hereby approved, a Validation Report must be submitted to and approved in writing by the Local Planning Authority. The Validation Report must confirm the assumptions as set out in the remediation plan (ref EX/PL/02 – Revision A) and Mineworkings…”
