As with all Council issues, the first 3 questions that always need answering are:
Ownership? - who owns or has responsibility for the Road, Highway, land or property? This is usually the landowner but may be a tenant. Suffolk County Council own mosts Highways in Suffolk. However, roads which are part of the National Strategic network such as the A47 Lowestoft area, are the responsibility of Highways England. Also, some roads and footpaths may be District Council responsibility (eg paths at rear of properties in Bonsey Gardens), and some may be private (such as The Lane in Wrentham).
Powers? - who has powers in relation to the property or issue? Sometimes "power" means power to enforce (eg a District Council using compulsory purchase powers). But most often, especially for a Parish Council, a power means a legal permision for the council to do something. A better analogy tor a parish council would be to think of it like the power to a drill to make it work. For Highways issues, Suffolk County Council has most powers.
Funding? - With all issues, it is good to know who is paying , or where the funding is coming from. Suffolk County Taxpayers fund Highways in Suffolk along with grants from Central Government.
There are various Highways related issues in Wrentham. Examples of thing that residents have expressed concern about include flooding & drainage, streetlighting, parking, and difficulties in crossing the A12 road. Find here some useful information.
