Did you know that you can tell Oxfordshire County Council and Cherwell District Council about highway road defects / overgrown verges and hedgerows etc using http://fixmystreet.oxfordshire.gov.uk/ ? There’s also a ‘phone app which is available for both iOS and Android so you can take a picture and quickly upload it to their system.
Don’t leave it for someone else to do, if you see something which needs reporting please do it! It’s far better to have it reported multiple times than not at all.
