The Planning and Highways Committee is responsible for a range of statutory functions related to town and country planning, development control, and highways in County Durham, unless these matters are delegated to an officer. It handles decisions on planning applications, limestone pavement orders, hedgerow protection, tree preservation, and public rights of way where objections are raised. The committee also provides guidance on the disposal of open space and public walks, and discharges licensing and regulatory functions for common land and village greens.
