Parking at the top of a cul-de-sac, pavements blocked

Eversley Avenue is a small cul-de-sac and it is proving to be a poor street to live on I have a drive which accommodates at least 2 vehicles and some days I can't get on or off it, occupants who have no driveways park there cars on the pavements causing problems for any cars/vans to turn round etc... It is very sad that when we have visitors with pushchairs they have to walk in the road as the pavement on most occasions are barely visible, daytime is not too bad however evening is appalling, whichever is a nightmare when we have children with various commitments.
