Eastern Developments submitted another modification application recently, hoping to slash its $328,748 parking contributions bill due to a shortage of spaces.

Although the parking at Quest has always relied on a valet arrangement, the proposed solution lay in adding two extra phases, stacking cars up to six deep as the motel's occupancy rate rose.

Council staff recommended only modes A and B be allowed, meaning cars would be stacked up to two cars deep, leaving $102,779 in contributions to pay.

Technical services director Ian Greenham said stacking six cars would mean a number of staff would be required to retrieve a vehicle quickly.

"Or you would actually be waiting a considerable amount of time for your vehicle," he said.

Councillor Kevin Duffy moved to also allow mode C, allowing up to five cars stacked, cutting the contribution to $59,043, leaving mode D as the only one not approved.

"We see [valet parking] all through Sydney and major centres as well where you see them putting cars on top of each other," he said.

Acting general manager David Waddell reminded councillors they were not voting based on how guests might react to the parking arrangement.

"Your decision is around if that happens and there's too much valet parking and it gets too difficult, will those customers spread out in the streets surrounding the motel?" he said.

Councillors Stephen Nugent, Joanne McRae and Tony Mileto voted against mode C - Cr McRae asked whether the decision would set a precedent for other developers to come up with "innovative and creative valet parking designs".

Acting development services director Mark Hodges said while the NSW Land and Environment Court took a council's consistency in applying policies into account, any developments with contributions paid would be unaffected.

Eastern Developments and Quest declined to comment.
