Supports of residents' parking zones in Bristol have condemned an anonymous leaflet criticising the idea.

Bristol City Council is planning to run pilot schemes in Brandon Hill and Kingsdown, after more than half the residents in each area expressed support during last year's consultation.

Residents' parking would see households charged for the right to park; £30 for one vehicle, £110 for two and £310 for three, and up to £50 on visitor permits.

Next week the council will send out questionnaires to the two areas asking for residents' views on the details of the pilot schemes.

But bright yellow leaflets have been distributed in Clifton making a claims about the down sides of introducing the zones.

The A4-sized leaflet states: "Although a slim majority of residents have expressed support, the huge reduction in parking space, particularly in the evenings and weekends can only increase the overall frustration incurred.

"The council has tried to hoodwink residents through claiming parking will improve but how can this be true if they are removing anything up to 25 per cent of parking space.

"The scheme could expand over time, eventually making it impossible for local residents to park in neighbouring zones.

"Areas just outside the pilot scheme will suffer reduced parking due to displacement."

The leaflet also includes a series of statements the council and supporters say are not true.

These include "driveways will be protected by double yellow lines" even though the proposal is that residents will be able to choose whether they have double yellow lines or not on their driveway entrance.

Another, that "one in 10 parking spaces will be converted to pay and display" is disputed.

Stephen Perry of the Yes to RPZ campaign said: "All of these unfounded claims are aimed at alarming and frightening people living in Clifton.

"The local authority's survey of residents in the pilot areas is to take place in April.

"The scheme design will not be finalised until the responses have been analysed.

"The yellow leaflet was not only posted through letterboxes but attached to cars parked in the area during the day, in an attempt to get commuters to lobby the council in opposition to the proposed pilot.

"This has happened in a week when the 'no' campaign acquired an unlikely supporter – the former Countdown celebrity, Carol Vorderman.

"Large numbers of people have subsequently complained that her intervention was unwelcome, being from someone who lives well outside the areas concerned."

The proposed pilot zones cover around 3,200 properties.

If they are backed by a majority they will go back to cabinet for the final say-so, with an aim to begin by the end of the year or early 2010.

Bernard Cooke of the 'no' campaign group "keep parking free" said the leaflets were nothing to do with his organisation.

A council spokesman said: "The yellow leaflet distributed contains many misleading and inaccurate statements.

"We will be writing to residents and surveying households with a view to drawing up a design for a scheme, which we will discuss with the whole neighbourhood in each area.

"At the end of this process, residents in the Kingsdown and Clifton will have the chance to vote 'yes' or 'no' to a final design for a scheme."
