31 The critical word in considering whether or not each of the proposals is consistent with this zone objective for the 7(b) zone is the word "enhance". The concept imported by the use of the word "enhance" is not merely evaluative or neutral in the attributes that must be ascribed to any development when assessed against this objective of the LEP - there must be some positive outcome of the development for the area - in this case each allotment.
32 There are no "special .............., aesthetic or scenic qualities" of the site - the element of this objective that is relevant is the "special conservational ......... qualities" of the site and its component allotments.
33 Although there are marginally different circumstances as the various building envelopes are able to utilise degraded areas of the site such as roadways or tracks to differing extents as part of the building envelope for each allotment, nonetheless these differences would not alter the circumstances for each of the allotments sufficiently to require different conclusions concerning them. Indeed, the interdependence of the six proposals makes it impossible to consider the benefits claimed by the company without considering them all as a package on matters such as site security or weed control.
34 It is the company's position is that there will be a positive contribution or enhancement to the conservational values of the site as a consequence of various activities that will result from the initial preparation phases (from time of consent to erection of the dwellings) and from ongoing benefits of occupation of the dwellings.
35 I therefore turn to consider both the benefits claimed by the company and the impacts that will arise - I do so to assess whether the overall result is an "enhancement" or not of the "special conservational ......... qualities" of the site.
36 The Rural Fire Service has published a manual entitled Planning for Bushfire Protection. This document sets out, for various types of development in bushfire prone areas, the protective objectives to be pursued and a range of appropriate measures to be implemented to ensure that the objective is achieved. Essentially, the aim of the manual is to endeavour to eliminate, as far as is possible, risk to the lives and well-being not only of occupants of properties in fire prone areas but also risk to the lives of emergency services personnel who may be called upon to respond to a fire. In addition, the manual includes objectives and implementation measures that are designed to afford the maximum reasonable protection to structures such as houses that are erected in bushfire prone areas. Planning for Bushfire Protection played a significant role for each of these proposed dwellings as a consequence of the provisions of section 79BA of the Environmental Planning and Assessment Act 1979 (the Act).
37 Each of the allotments requires the construction of the access road from the end of the bitumen sealed internal roadway to the public road running along the southern boundary of the site. This is a consequence of the requirement in Planning for Bushfire Protection that any dwelling that is more than 200 m from a public road requires two egress routes to reach a public road. The consequence of this requirement is that the construction of all weather two wheel drive egress to the public road to the south will require clearing of elements of that bushland. This impact will arise whether approval is given for all six dwellings or for some lesser number.
38 For the house sites on all allotments (other than Lots 4 and 5), road upgrading to all weather two wheel drive standard will be required for varying lengths of existing internal bush tracks - tracks that are of varying present construction standards but less than acceptable two wheel drive standard at present.
39 Further, regular maintenance by trimming of vegetation along the sides of the internal access roads will be required to ensure that the necessary vehicle clearances are maintained on an ongoing basis.
40 First, the company says that the initial road reconstruction elements involve addressing and rectifying present problems of erosion, drainage and the like. However, there will also be the countervailing influence of the necessity for significant upgrading of all the necessary internal roads apart from the one that is presently bitumen sealed. These impacts will include the clearing of elements of vegetation not merely to ensure minimum carriageway widths are established but also, at appropriate locations designated in the internal road network plan, to permit passing bays required by Planning for Bushfire Protection, to be incorporated.
41 Even if, for example, only the development on Lot 1 or Lot 5 were to be approved, there would still be the necessity for the construction of the access road to the public road along the southern boundary.
42 As a consequence, although there will be some benefits from the construction of the internal road network, there will also be countervailing adverse impacts. At the very best, in my view, the overall weighing of benefits and impacts from the initial road reconstruction (if it were a minimalist model) could be described as neutral at its highest.
43 On the other hand, it was obvious from the site inspection that the greater the length of track reconstruction that is necessary, particularly of the loop road to service the two northern building envelopes, the greater the likelihood that the impact would be negative rather than neutral. It is certainly not appropriate assume that the road construction activities of the maximum construction of the whole of the necessary internal network, would result in an enhancement of the "special conservational ......... qualities" of the site for the purposes of the first zone objective.
44 The possibility of preventing environmental impacts from construction and ongoing occupation of the various building envelopes, apart from the initial clearing to meet the asset protection zone requirements of Planning for Bushfire Protection, is dealt with in a later section of this decision dealing with the question of reasonableness of the necessary conditions of development consent for this to be realised.
45 I proceed, therefore, on the basis that those conditions could provide a framework with the potential to render the erection of all of the dwellings, on the individual building envelopes, neutral in an environmental sense. However, it is not possible to disregard the fact that clearing of over 6.5 ha of bushland is a necessary precursor to erection of these dwellings. This bushland is agreed by the experts to be in a largely unmodified state (the exception being degraded land comprising part - but not the entirety - of the building envelope on Lot 1). This bushland would need to be cleared to the extent necessary to meet the asset protection zone requirements of Planning for Bushfire Protection for these dwellings to be permitted. This involves removal of virtually all vegetation in the inner asset protection zones (these comprising the bulk of the areas to be cleared - with all vegetation able to be retained to be slashed to 10 cm high on a regular basis). The house footprints, self-evidently, require the removal of all vegetation. Although some trees may be retained in the outer asset protection zone, their canopies may well require maintenance pruning (depending on the extent that trees are possible to be retained).
46 The building envelope on Lot 1, (although more degraded as it incorporates not merely part of the internal road network [as is the case with each of the other building envelopes] but also incorporates a track intersection and portion of two other tracks together with an area that has led some environmentally unfriendly fill placed on it in the past), nonetheless still involves the clearing of an element of undisturbed bushland. None of this bushland clearing could possibly be regarded as an enhancement of the "special conservational ......... qualities" of the site for the purposes of the first zone objective.
47 As discussed later in more detail concerning the reasonableness of the necessary conditions of consent, there is already, on all the allotments, significant weed infestation. Weed infestation, in this context, relates to two types of plant. The first of these are weeds that are categorised by statutory proscription and with respect to which there is a statutory obligation to undertake weed control measures. The second category is those that are environmental weeds - being plants that are undesirable in their local bushland context but which are not proscribed and where, therefore, the "obligation" to remove or control them is a moral and environmental one rather than one imposed by statutory obligation.
48 With respect to weed control generally, the company is currently spending $20,000 per annum on weed control. No evidence was given as to the proportion of this sum that might be regarded as applied to meeting statutory obligations and the proportion of the sum that might be regarded as applied to meeting the moral or environmental "obligations". For reasons which follow I do not consider that such issues of apportionment would make any difference in these proceedings.
49 To the extent that weed control is a statutory obligation, the company is obliged to undertake it whether or not these dwellings are permitted. The statutory obligation for weed control will not change whether or not the dwellings (any or all) are permitted. This aspect of weed control cannot constitute enhancement of the "special conservational ......... qualities" of the site for the purposes of the first zone objective.
50 However, to the extent that the company is undertaking environmental weed control, it is doing so against a moral or environmental "obligation" only. To the extent that such a moral or environmental "obligation" would be able to be transmuted by conditions of development consent to statutory obligation would represent an enhancement of the "special conservational ......... qualities" of the site for the purposes of the first zone objective.
