Windows and sunlight
20The 4 windows are on a sunroom at the rear of the applicant's dwelling. Windows 1 & 2 face north and windows 3 & 4 face west. The applicant did not give precise answers to questions 4 and 5 in the Part 2A application form regarding the number of hours per day of sunlight lost to each window nor were any shadow diagrams provided.
21Based on the oral evidence given on site and during the hearing, the applicant contends that windows 1 and 2 lose sun in winter from about 12.30 pm and windows 3 and 4 from about 1.30 pm.
22Under s 14E(2)(a)(i):
(2) The Court must not make an order under this Part unless it is satisfied:
(a) the trees concerned:
(i) are severely obstructing sunlight to a window of a dwelling situated on the applicant's land, or
If a severe obstruction is found, the Court must then consider s 14E(2)(b) which states:
(b) the severity and nature of the obstruction is such that the applicant's interest in having the obstruction removed, remedied or restrained outweighs any other matters that suggest the undesirability of disturbing or interfering with the trees by making an order under this Part.
This balancing of interests requires consideration of matters in s 14F.
23In this matter I am not satisfied that there is a severe obstruction of sunlight to windows 1 and 2. These face north and the respondent's trees are to the northwest. These windows, by the applicant's admission, receive sun until at least 12.30 pm in winter. There was nothing on site to suggest that the morning sun is obstructed. At 9.30 am on the day of the hearing the windows were receiving sunlight.
24As determined in several matters heard by this Court, including Ball v Bahramali [2010] NSWLEC 1334, the typical council planning controls that apply to solar access in development applications can reasonably be applied to applications under Part 2A of the Trees Act. These controls typically require at least 3 hours of sunlight to at least 50% of the area of living room windows between 9.00 am and 3.00 pm on 22 June, that is, the shortest day.
25I am satisfied that that windows 1 and 2 would receive at least 3 hours per day in mid winter. Similarly, I am not satisfied that the shadow cast from trees 1, 6 and 7, being the only trees in the application that meet the jurisdictional test in s 14A(1), could be singled out as causing any significant loss of sunlight given the other trees on the site that were not nominated or which do not satisfy s 14A(1). I also note that there is a dwelling to the north of the applicant's property and there is a large palm tree in the rear garden of this property in the vicinity of trees 1, 6 and 7. These objects may also restrict sunlight when the sun is low in the winter sky.
26With respect to windows 3 and 4, again putting the applicant's case at its highest, I am prepared to consider that there is a severe obstruction of sunlight to them. However the extent to which that obstruction is due to the trees in question is unclear. S 14E(2)(a) requires a nexus between the trees concerned and the severe obstruction of sunlight. However, in giving the applicant the benefit of the doubt, I will progress to the next stage of the determination and consider the matters in s 14F.
27Relevant to this matter are the following cluses:
(a) The trees, now limited to numbers 1, 6 and 7 are on adjoining land and are no closer than about 18 m from windows 3 and 4.
(b)(c) The trees were planted about 15 years after the construction of the sunroom and have grown to their current height during that time.
(g) The trees are likely to contribute to the local ecosystem and to biodiversity; this is a reason for their planting.
(h)(i)(l) The trees contribute to the natural landscape and scenic value of the property on which they are growing and to the locality. They can be seen from nearby properties and streets and therefore have intrinsic value to public and private amenity.
(k) Impact of pruning: Trees 1, 6 and 7 have the typical form of maturing Eucalypts with generally terminal foliage and substantial distances between branches. Given their height and branch arrangement, reduction pruning techniques to achieve the extent of reduction requested by the applicant could not be carried out in accordance with AS4373:2007 Pruning of Amenity Trees . Any reduction to approximately half their current height would result in the proliferation of weakly attached epicormic shoots that may result in structural problems. While some lesser reduction may be possible in the short term, ongoing crown reduction of Eucalypts is generally impractical.
(m) Any other obstructions: As previously stated, there is a Cocos Palm of some stature at the rear of the adjoining property near trees 1, 6 and 7 between those trees and the applicant's property. There is a mature Juniperus sp to the west on the property adjoining both the applicant's and the respondent's properties. There is a mature Brush Box on the diagonally adjoining property to the southwest. These are located upslope of windows 3 and 4 and are of a size that would cast a reasonably long shadow in winter afternoons.
(n) The respondent has removed 4 trees along her rear boundary fence and has pruned at least 2 others. There are gaps between and through the canopies of the trees. The trees removed were in a row and would most likely have satisfied the test in s 14A(1).
(o) As previously mentioned, the applicant was unable to provide precise details as to how much sun was lost over which part of the day. This consideration of the matter is based on giving the applicant the benefit of the doubt.
(p) The trees are evergreen and therefore provide shade all year round.
(s) Other matters: Of relevance is the slope and aspect of the site. The applicant's property is on a moderately sloping, east facing slope. Windows 3 and 4 are approximately 15m down-slope of the rear fence and the ground level at the rear of the house is about 1.5m lower than ground level at the rear boundary. Valetta Street is upslope and to the west, hence dwellings and associated trees at the rear of properties on the eastern side of Valetta Street, as well as those on the western side, will inevitably interfere with afternoon sun in winter when the sun is lower in the sky.
