RESIDENTS have launched a petition objecting to plans for the redevelopment of Lion Green Road car park.
CCURV, a joint body of the council with developer John Laing, wants to put a Waitrose and health centre on what is now a council-run car park.
But opponents say the scheme will cause chaos, especially alongside forthcoming development of Cane Hill.
The planning application submitted in July details plans to replace the 200 all-day parking spaces with 190 spaces for the supermarket and 12 for the health centre.
Developers want the supermarket's to be short term and enforced by pay-and-display.
They add that "management of the car park would be agreed and conditioned with the local highway authority".
They hope to send longer-term parking to Coulsdon South station.
Resident Peter Morgan drafted a statement of opposition to present to the council. Mr Morgan says the all-day parking on the site must stay.
The statement reads: "There is no other all-day public parking in Coulsdon, and side streets are intensively parked over a wide area."
Objectors also say the developers' transport assessment is "fanciful."
It adds: "People won't walk 25 minutes nor switch to cycling. Lion Green Road is regularly saturated, with long queues back into Brighton Road and beyond.
"The current plans mean more traffic with no extra capacity, and serious delay would result."
Richard Thurbon, chair of the Coulsdon West Residents' Association, said he would also object to the application.
"Our residents have told us that many of them would have no issue with a supermarket; they do have a issue with traffic and parking.
"Therefore, I will object on the grounds of poor assessments of traffic, removal of vital parking, and impact on the area."
EPR Architects say the work would not have "any unacceptable residential amenity impacts", adding that it would provide jobs and "generate wealth".
A consultation is open until Thursday, with a decision expected in October.
