9 PBP refers to vegetation management in APZs and states at 6.2.1 (p 16):
To produce a garden that does not contribute to the spread of bushfires, it is necessary to plan the layout of the garden beds and take an active decision to minimise certain features in favour of other features;
…
· plant trees such that
- the branches will not overhang the roof;
- the tree canopy is not continuous; and
- there is a windbreak in the direction from which fires are likely to approach.
…
Expert evidence
10 The Applicant relied on the evidence of Mr Swain, a bushfire control expert, who considers cypress pines are unsuitable and not in conformity with PBP because it is a tree which produces excessive quantities of fuel, retains dead material and is combustible. His views were informed by studies made after the major bushfires in Canberra in 2003. The Respondent relied on the expert evidence of Mr McMonnies and Mr Eadie, bushfire control experts, who considered the measures in place on the Respondent's property did comply with PBP. With ongoing maintenance of the hedge to limit its height, remove dead wood and ground fuel on a regular basis, these measures are adequate. The sprinklers installed were added protective measures in their view.
11 There was joint conferencing by the experts. They commented on the three bullet points from PBP raised in the APOC par 11. They agreed the cypress pine hedge was a continuous canopy. Mr McMonnies and Mr Eadie considered the hedge was sufficiently separated from the Respondent's dwelling and the rear bushland to be discontinuous with the fire source at the rear and therefore satisfactory under PBP. Mr Swain considered there was a risk of ignition as a result of the existing hedge and that the separation from the dwelling was not sufficient. On whether the cypress pines were a species that retains dead material or deposits excessive quantities of ground fuel in a short period, Mr Swain considered they were of that type and were too close to the dwelling to prevent ignition by direct flame or radiant heat emission. While Mr McMonnies and Mr Eadie agreed that the cypress pines were a hedge with a continuous canopy, they considered the hedge was located far enough from the dwelling and the bush at the rear so that it was discontinuous. They did not consider the dwelling would be likely to be ignited by direct flame contact or radiant heat emission.
12 Mr McMonnies and Mr Eadie agreed that the pines were acceptable provided a regular ongoing maintenance regime was implemented in accordance with the requirements for an inner protection area specified in s 4.2.2(b) of PBP. This included maintaining the hedge at a fixed height and maintaining the substantial gap between the Respondent's dwelling and the rear bushland, regular pruning of dead material in the hedge and removal of ground fuel. A landscape management plan with appropriate protocols was needed and/or a s 88B instrument to ensure the obligation continued to be implemented by the Respondent. Mr Swain considered the cypress pines should be removed and a different species of tree planted at intervals if so desired.
Applicant's submissions
13 The Applicant's primary case is that when condition 27 was imposed in October 2003 the Respondent was then required to manage his property in accordance with condition 27. He should have removed the cypress pines then. That obligation commenced from the date of development consent because s 83(1)(a) of the EPA Act specifies that is the date from which the consent becomes operative and effective. Condition 27 relates to the whole of the Respondent's property and there was a use of that property for residential purposes as at October 2003. While a "passive" use may not amount to an unlawful act an "active" use can constitute the carrying out of development; Minister Administering the Crown Lands Act v New South Wales Aboriginal Council [No 2] (1997) 42 NSWLR 641 per Handley J at 643-645. As the Respondent was occupying his property for residential use when the consent was granted the obligation to comply with condition 27 arose at the date of consent.
14 Whether there has been "physical commencement" of the work approved under a development consent required to prevent a consent lapsing under s 95 of the EPA Act, is not the test for the date on which a consent becomes enforceable. A use may commence without any physical works being required. The enforcement of an operative and effective consent does not need to await the subjective decision of the consent holder to "activate" the consent. Further, a development need not be "complete" in order to ground an obligation to comply with conditions as some conditions require compliance in the course of carrying out development; Rao v Canterbury City Council (2000) 112 LGERA 360 at [20]-[21] per Mason P.
15 Condition 27 required the Respondent to manage his property in a certain way. "Manage" is defined in the Macquarie Dictionary, Revised Third Edition 2001 inter alia as "to succeed in accomplishing a task, purpose, etc".
16 The Applicant addressed the provisions of PBP in some detail and emphasised that it was directed to the reduction of fire hazard based on planning for protection measures assuming maximum hazard. The three matters identified in the APOC par 11 were required to be complied with, that is, the presence of shrubs or trees is acceptable if they are well spread out and do not form a continuous canopy, are not species that retain dead material or deposit excessive quantities of ground fuel in a short period or a danger period, and must be located far enough away from the dwelling so that they will not ignite it by direct flame or radiant heat emission. The provisions of PBP required that the Respondent remove all the cypress pines along the boundary as, based on Mr Swain's evidence, those trees are not suitable for a property being managed as an inner protection area. They are a species which retain dead material or deposit excessive quantities of ground fuel. Further, as presently located they form a continuous and unbroken hedge along the boundary and are not well spread out. Despite being presently separated from the dwelling by a 4m gap the hedge still poses an unacceptable risk based on Mr Swain's evidence. The hedge is not located far enough away from the Respondent's dwelling to ensure it will not ignite the dwelling by direct flame contact or radiant heat emission.
17 In the alternative, if the date of the grant of development consent is not the date on which the obligations under the consent came into force, the obligations under the development consent certainly operated once steps were taken to carry it out. Those steps were taken when the application for modification of the development consent was made and the commencement of building work occurred sometime in February 2007. There is evidence of failure of the Respondent to manage his property, as can be seen in the photograph taken by Mr Swain in October 2007 which shows the hedge has not been kept at the lower height of 3.5m - 4m, and formed a continuous canopy on that date.
