There is a very detailed Standard complied by the most knowledgeable people in this field.
It clearly states what features a compliant cattle grid should have.
It is the legal duty of Loal Authorities to follow standards when they have the choice.
The country is littered with none standard cattle grids
Tatton Park is no exception. There are a number of Cattle Grids most of which are non compliant.
A cyclist had a heavy fall on one and was lucky to avoid serious injury some months ago. His bike was a write off.
The cyclist complained to the Site Management. and was airily dismissed.
The site is owned by the National Trust and managed by Cheshire East Council
They chose the wrong person to rebuff. The injured party has the professional skills, energy and determination to pursue the matter
The case came to court. Astonishingly the Judge dismissed the case even though a letter from your Guru (a Chartered Engineer) stated that the grid did not comply with the British Standard.
It makes one wonder why we have British Standards at all.
