Technical guidance notes

The technical guidance (TG) notes detail what the adoptable standards are within Hampshire. These documents form part of the framework of the material use policy and commuted sum policy. This aims to ensure appropriate use of materials and minimising long term maintenance costs. The guidance informs developers of what Hampshire County Council will accept on the highway network early in the design proposal stage.
