Section 106 Statutory Authority and Restoration Bonds

Local authorities protect rural land from derelict infrastructure through statutory planning deeds:

• Planning Authority Agreements: A local planning authority may enter into an agreement with any person interested in land in their area for the purpose of restricting or regulating the development or use of the land, either permanently or during such period as may be prescribed by the agreement.

• Screening Scale: Formal screening by the local planning authority is required where The area of the development exceeds 0.5 hectare.

WEEE Compliance and Material Recovery
