Parking and driving on the green and littering

Neighbours in the area and the flats opposite are driving their vehicles and parking them on the grassy green verge, on both sides of Cunningham Avenue EN3 6LA Clearly no vehicles are allowed on here as has been the case for last 16 years since I moved here. It appears they receive the odd parking ticket but this is not deterring them and the green is now destroyed and very unsightly with tyre tracks on the grass. The tyre tracks have made a driveway on the grass Most of the properties are let and the tenants have no regard or respect for the area or for us homeowners who take pride in our neighbourhood I feel that this would not be tolerated in other more affluent areas of the borough such as Winchmore Hill, The Ridgeway etc. Furthermore on the corner of Cunningham Avenue and Mandeville Road, it has become a dumping ground for excess rubbish from the flats. Neighbours are dumping refuse sacks of rubbish on a regular basis
