46 The contributions plan divides the local government area into various precincts. The subject development is located in the Lindfield precinct. According to section C2 of the contributions plan: - (i) excluding regional parkland, there is 6.3 sqm of open space (parks) per person in the area, (ii) this provision of open space (0.63 hectares per 1000 people) is relatively low, and unevenly distributed, with some areas (such as Roseville, Lindfield and Gordon) having less than this area average. Lindfield, for example, has only 3.77 sqm of parkland per person, (iii) it would be desirable to acquire open space at least at the current (relatively low) per capita level of provision for the area as a whole, (iv) because of the high cost of land in the area, no contributions will be levied for the acquisition of additional active open space (sports fields and courts), but existing facilities will be embellished to make them "work harder", (v) for parkland open space, a different approach is required, based on "differential acquisition by precinct" (due to the uneven distribution of such open space throughout the area), (vi) the differential acquisition is to be based on a "weighting factor" which discounts proposed acquisitions at the precinct level according to a deemed appropriate benchmark (being 5.82 sqm per person), and differences between precincts in terms of both the existing quantity and accessibility of open space. For the Lindfield precinct (with only 3.77 sqm of parkland presently per person, and an expected population increase in the period 2004 to 2009 of 910 people), there is no discount from this benchmark, so the per person land requirement acquisition is 5.82 sqm (or 5,296.20 sqm), at an estimated cost of $6,715,582 (that is, $7,379.76 per person). Paragraph 27.73 of the contributions plan provides that the Council is to commission an open space acquisition planning study to identify sites for acquisition, and to ensure that the new open space is appropriately configured to meet the open space needs of new residents.
