that the person be joined as a party to the appeal."
11 The power of the Court under s 39A is discretionary as appears from the use of the word "may" in the section. Ms Butler proposes to raise a number of issues which she says have not been adequately addressed by the Council either in its reasons for refusal or in its notice of contentions.
12 The affidavit in support of the motion for joinder seeks to raise the following contentions, namely, visual impact of the utilities block, soil compaction and run-off from parking, buffer distances to watercourses and drainage depressions, stock movements in Bents Basin Road, flooding, location of the effluent treatment system, impact of climate change, noise from traffic movements and impact of increased traffic. It seems that the principal issues that Mr Butler seeks to raise are also raised by the Council in its notice of contentions.
13 The question of visual amenity and views has been raised in the Council's contentions six and seven. The issue of the impact on water quality and on the river has been raised in contentions three, four and eight. The impact on the river by effluent disposal has been raised in contentions three, four, eight, nine and ten. The impact on Bents Basin Road regarding the increased traffic movements has been raised by contention five. The question of flooding has been raised by contentions two and eight. The location of the sewer management system on the flood prone land has been raised in contention three. The issue of climate change is closely associated with traffic, as raised in contention five and the proposed alleged impact upon the rural character and alleged ability to cause rural land use conflicts are addressed in contentions seven and eight. Acoustical impact upon the surrounding locality has been raised by the Council's statement of contentions in contentions one and eight and, as I have noted, increased traffic generally has been raised in contention five. Each of these issues would thus be sufficiently addressed. The consent authority is, of course, required to consider impacts upon the environment generally under the Act and is also required to consider the principles of ecological sustainable development. All of these matters will, of course, be considered by the commissioner hearing the appeal.
