Worried people have called for action over parking in their roads, amid fears emergency vehicles would be unable to get down streets clogged up with cars.
People in Wellesley Avenue South and Cintra Road are concerned thoughtless parking by people who do not live in the streets leaves too small a gap for fire engines and ambulances to squeeze past.
They say the Thorpe Hamlet streets are swelled by up to a 100 cars belonging to football fans when Norwich City play at home and by commuters on weekdays.
They are making a fresh call to council bosses for consultation on the introduction of parking permits to be done.
Last year, they presented a petition at City Hall, but were told resources to carry out consultations was limited and other streets took priority.
Chris Dunn, who lives in Wellesley Avenue South, said firefighters had tested whether a fire engine could get down the road and agreed it was a problem.
Mr Dunn said: 'We have a mix of elderly persons and young families living here. Residents are fearful that emergency vehicles at times will not be able to access all properties quickly and easily owing to the increasing number of non-resident vehicles parking.
'On football match days up to a 100 extra vehicles choose to park in these two roads which has access only at one end and finishes in a cul-de-sac at the other end.
'This extra volume restricts the road width and often blocks footpaths and driveways.
'Commuter parking has increased dramatically and inconsiderate parking often leaves restricted access during weekdays. It would appear a major incident has to happen first before any action is taken.
'Funding should not be an issue when it comes to health and safety.'
Lesley Grahame, Green city councillor for Thorpe Hamlet, said: 'I urge the city and county Council to work together to make it easier for people to leave their car at home.'
A spokeswoman for Norwich City Council said officers were looking to carry out consultation over parking permits in the roads next year.
But she said, in the immediate future, the focus was on two permit parking schemes in Lakenham and in streets around the University of East Anglia.
