(c) preventing the fragmentation of grazing or prime agricultural lands, protecting the agricultural potential of rural land not identified for alternative land use, and minimising the cost to the community of:
(i) fragmented and isolated development of rural land, and
(ii) providing, extending and maintaining public amenities and services, and
(d) protecting or conserving (or both protecting and conserving):
(i) soil stability by controlling development in accordance with land capability, and
(ii) trees and other vegetation in environmentally sensitive localities where the conservation of the vegetation is likely to reduce land degradation or biodiversity, and
(iii) water resources, water quality and wetland areas, and their catchments and buffer areas, and
(iv) land affected by acid sulphate soils by controlling development of that land likely to affect drainage or lower the water table or cause soil disturbance, and
(v) valuable deposits of minerals and extractive materials by restricting development that would compromise the efficient extraction of those deposits, and
(e) reducing the incidence of loss of life and damage to property and the environment in localities subject to flooding and to enable uses and developments consistent with floodplain management practices.
The evidence
17 The applicant provided expert evidence from:
o Dr David Robertson, ecologist,
o Mr John Travers, ecologist,
o Mr Stephen Cooper, acoustical engineer,
o Mr Ronald Brown, traffic engineer,
o Mr Bob Staniland, civil engineer,
o Mr Brian Wright, soil conservationist, and
o Mr Greg Smith, town planner.
18 The applicant provided lay evidence from Dr Richard Cardew, a member of the Historic Sports Racing Club of Australia. He stated that the proposed development needed to be considered as a regionally significant development; there being only four motor racing tracks remaining in New South Wales. He questioned whether the matters required to be protected by the council are so important that they should be protected at all costs and that the development was likely to provide greater protection of flora and fauna than if the site remains undeveloped.
