Surlingham Parish Council has no power to force householders/landowners to maintain hedges/shrubs on their boundaries. That responsibility lies with Norfolk County Council (NCC) Highways Department.
Householders do have a responsibility to ensure hedges/shrubs do not encroach footpaths. The first step should always be for the parishioner to approach the householder and explain the problem.
If the Parish Council is contacted a polite letter will be sent asking the householder to comply with the request. However, the complainant should consider contacting NCC Highways if the problem persists.
Thank you for your understanding.
