Lateral extents

What is a lateral extent search?

The search is used to determine the highway boundary area of an adopted road which is a road maintainable at public expense.

Confirmation of the boundary is often requested during the house purchasing or conveyancing process. For example to establish whether a property is connected to a public road without the need to cross land owned by a third party.

It is also useful for planning applications, identifying the boundary of the highway, and to confirm responsibility for verge areas.
