The proposed rear setback to the north eastern boundary is inadequate.
(a) Clause 12.6 of DCP21 states that built structures must be a minimum of 6.5 m from the rear boundary. The rear boundary is the boundary between the site and 292 Whale beach Rd, Palm Beach to the north east. The proposed deck is located within 0.5m of the rear boundary.
(b) The location of the proposed deck within 0.5m of the rear boundary:
results in insufficient area for appropriate landscaping between the properties including screen planting of the undercroft;
exacerbates the bulk and scale of the built form of the site; and
lacks spatial separation impacting on the amenity of the adjoining property known as 292 While Beach Road. Palm Beach.
Controls
Clause D12.6 of DCP 21 -- Side and rear building line.
Clause D12.13 of DCP 21 -- Construction, Retaining walls, terracing and undercroft areas.
Site Coverage
2. The proposed deck will result in excessive site coverage.
Particulars
(a) Clause D.12.10 of DCP 21 specifies the maximum site coverage of 40% (206.9 m2 for the site).
(b) The excessive site coverage:
reduces the opportunity for vegetation to be enhanced to visually reduce the built form; and
does not reduce stormwater.
Controls
Clause D12.10 of DCP 21 -- Site coverage -- Environmentally sensitive land."
The planning evidence
14 The council relied on the evidence of its internal planner, Ms Ralph, who prepared the joint report with the applicant's town planner, Mr Goldsmith (exhibit B). Both planners gave oral evidence about the issues onsite and concurrently, at the resumed hearing in Court.
15 The Court also heard the oral evidence of the objectors to the application who spoke to their written objection lodged with the council and included in the bundle of documents tendered to the Court.
16 In an attempt to resolve the issue about the rear setback, the experts and the objectors gave evidence about 4 alternate setback designs for the deck as follows:
1. the original deck design with a 0.5 m setback off the rear north eastern boundary;
2. the applicant offered an amended design with a 2m setback off the rear north-eastern boundary apart from an area of 1.8 m in the north-eastern corner, which contains the pool cover to the irregular shaped pool;
3. the council offered to relax the DCP requirement and agree to a 4.25m setback off the rear north eastern boundary;
4. the objector suggested an acceptable setback at 3.5m off the rear north eastern boundary.
17 The alternate setback designs were drawn on plan and tendered with draft conditions at the conclusion of the evidence (exhibit G). I was able to understand the evidence and the impacts of the 4 alternate setbacks because the hearing was conducted in part onsite. At the site, I observed the site's steep topography; the existing built form on the site (well in excess of council's current site coverage controls), the existing, irregular shaped elevated pool (with no current access) and the existing pool cover extending 1.8m along the rear boundary.
18 It was clear from my view that a deck of some dimension is necessary to provide safe access to the pool area. Furthermore, it was clear from my view that, given the slope of the land, a north eastern facing deck on this site would provide a very usable private open space for the occupants of the dwelling.
19 I also inspected the objectors' property that adjoins the north eastern boundary of the site. The objectors' land also slopes steeply and contains a multi level dwelling that is orientated to the ocean views to the north east. I observed the objectors' property has elevated decks and patios on their dwelling facing the view to the water. Their rear yard adjoining the site is grassed and steep and contains a clothes line and what appears to be an aviary. Apart from two Cheese Trees and small vegetation, it looks directly at the undercroft of the applicant's cement pool built about 0.5 metres from the common boundary. The area where the elevated deck is proposed is also visible through the existing vegetation. I appreciate the impact that the elevated deck would have on their amenity if built in close proximity to the rear boundary. I understand their concern for the integrity of the existing retaining wall near that boundary and the damage that might be caused by storm water runoff onto their land through the retaining wall from the deck.
Council's evidence
20 The rear boundary setback controls in cl D12.6 of DCP 21 require "that built structures must be a minimum of 6.5m from the rear boundary." Ms Ralph, consistent with her written evidence in the joint report, accepted that in the circumstances of this case the DCP control in respect of the rear setback could be relaxed. However, she did not accept as proposed by the applicant's expert that the 0.5m rear setback in the application is sufficient setback because it does not achieve adequate landscaping, spatial separation or "…a more compliant site coverage". In her opinion, without the existing Cheese Trees between the site and the objector's property, the deck at 0.5m off the rear boundary would enable a direct line of sight into the objectors' rear yard. This would in her opinion also expose the undercroft of the deck, and without appropriate landscaping create an unappealing visual outlook for the objectors from their rear open space. Her evidence is that a 0.5m and 0.2m setback does not achieve the desired outcomes in cl D12.6 of the DCP. Council's evidence is that the desired future character of the locality is best achieved if the bulk and scale of the built form is minimised. A reduction in built form will according to Ms Ralph, ensure a reasonable level of privacy, amenity and solar access within the development site, and that in turn will enhance the character of the area.
21 In Ms Ralph's expert opinion, however, because of the constraints of this site, council would agree to a variation of the requirement in cl D12.6 concerning side and rear building line setbacks which prescribe a 6.5m setback at the rear to allow a 4.25m rear boundary setback for the deck. In her opinion, a 4.25m rear setback would adequately address her concern about the spatial separation between the deck and objectors' property. Ms Ralph's evidence is that the outcomes of the DCP control are adequately satisfied by a 4.25m setback because it would allow for appropriate landscaping to address the bulk and scale of the development when viewed from the objector's private open space at the rear of their property. She was satisfied it would also adequately address the issues of overlooking and privacy. She was critical of the 2m setback because in her opinion it would not allow sufficient space for landscaping and it would not provide sufficient space between the deck and the adjoining neighbour to the north east. While she conceded that the existing built form currently exceeds the maximum site coverage control in cl 12.10 of the DCP, she was of the opinion that a setback of 0.5m would increase the site coverage to 65%. In her view, that was excessive and unacceptable because it exacerbated the breach and further reduced the opportunity for vegetation to enhance and visually reduce the built form.
22 She was also concerned that site coverage of 65% could have adverse impacts on the stormwater runoff from the property onto the objectors' land. For those reasons, she suggested a smaller deck with a setback of 4.25m on the site would be the best design to achieve the outcomes in the DCP.
Council's submission about the previous deck
23 Council submits that I must disregard the applicant's evidence about the previous deck on the proposed location because it is not relevant to this appeal pursuant to s 97(1) of the Act for a new deck. Evidence is only relevant if it relates to a matter in s 79C(1) of the Act. Council relies on the principle in Zhang v Canterbury City Council [2001] NSWCA 167 and submits that .the DCP must be the focal point of my consideration of the evidence and I must have a real and genuine consideration of the relevant provisions clauses D12.6 and D12.10 of the DCP 21 and the outcomes in those controls in the particular circumstances of the case.
24 Furthermore, council submits that I should have regard to the Court's reasoning in the existing use case of Stromness Pty Limited v Woollahra Municipal Council [2006] NSWLEC 587 para 87 and accept that in this appeal there is no entitlement to a development consent. There is only an entitlement to make a development application that is then to be assessed on its merits in accordance with s 79C(1). In other words, the applicant is not entitled to a deck in the same location or for that matter the same size or setback unless it is acceptable under s 79C merit assessment.
The applicant's evidence
25 The applicant argued that it is relevant to have regard to the fact that the deck was approved previously for the proposed location. The applicant in saying that submits that to disregard such a fact is against the public interest because if that is the case, if I understand his submission correctly, then no-one will lodge a DA for the replacement of deck, but rather allow the structure to deteriorate because there can be no guarantee that they will get an approval to rebuild the deck.
26 Apart from that submission, the applicant says the deck with a setback of 2m is appropriate and that based on the planning evidence of Mr Goldsmith the outcomes of the DCP controls will be achieved by the increased setback from 0.5m to 2m and the conditions imposed on the consent and given the particular circumstances of this case it is appropriate where necessary to vary the DCP setback and site coverage controls.
27 The applicant's planner, Mr Goldsmith, said that the DCP controls for the rear setback and site coverage are generic and not site specific. In his opinion there is justification in this case to vary those controls because of the specific constraints of the site, which make it unreasonable to require 6.5m rear boundary setback or 40 per cent site coverage. His evidence is that the steep fall of the site together with the existing built form and small outdoor living areas on various levels makes compliance with the 6.5 setback control, unworkable.
28 His evidence is that a deck built with a 6.5m setback on this site would result in unusable open space for the deck. In Mr Goldsmith's opinion, numeric compliance with the setback control on this site will not achieve the outcomes of the DCP. In his opinion, the outcomes of the control are better achieved with a 2m setback and appropriate screening by landscaping. In his opinion the outcome of minimising bulk and scale of built form and ensuring reasonable level of privacy, amenity and solar access within the site and adjoining residential properties can be achieved with a setback of 2 m to provide landscaping is to visually reduce the built form.
29 His evidence is that a 2m setback would provide sufficient space to import proper soil and species including at least three trees of 4m to adequately landscape the north eastern rear boundary. In his opinion, planting appropriate species in the undercroft of the elevated deck will also reduce the bulk and scale of the built form and address the objectors' concern about the undercroft area appearing unsightly. Mr Goldsmith's evidence is that the conditions proposed by council, which the applicant accepts, will ensure that the outcomes of the DCP will be achieved despite numerical non-compliance with the setback control and forty per cent site coverage control. The result will be a reduction of bulk and scale of the elevated deck when viewed from the objectors' rear open space.
30 Mr Goldsmith gave evidence that his client would accept and implement council's landscaping conditions including a condition in respect of species and maintenance of the landscaping.
31 Condition C6 of the draft conditions requires prior to the issue of a construction certificate a landscape plan approved by council with the following objectives:
a. Dense screening of the deck undercroft, with the vegetative screening located immediately adjacent to the north eastern elevation of the deck, with a mature height to that of the balustrade of the deck.
b. The terraced area between the north-east elevation of the deck in the rear boundary is to be landscaped with medium to dense vegetation with a mature height of at least 4 m; and
c. Vegetation should comprise locally native evergreen species suitable for the location.
32 Condition C7 requires that the landscape plan shall be accompanied by a certificate from a suitably qualified structural engineer to the effect that:
a. The proposed landscaping will not affect the structural integrity of the existing retaining walls.
33 Condition 8 requires a stormwater management plan prepared by a suitably qualified stormwater engineer is to be submitted to the Council prior to the issue of the construction certificate. The management plan shall detail the proposed method of deck stormwater drainage, ensuring the proposed method will not affect the structural integrity of the existing retaining walls on the rear boundary.
34 In Mr Goldsmiths' expert opinion, a line of sight drawn from a person standing on the deck with a 2m rear setback would not look directly into the objectors' rear yard if landscaped appropriately. His evidence is that the council's proposed conditions adequately deal with the landscaping issues and the stormwater runoff from the deck and the impact of the construction of the deck on the integrity of the north-eastern retaining wall.
35 The applicant's evidence is that the DCP outcomes will be satisfied with the deck being setback 2m from the rear boundary. Mr Goldsmith rejected the 3.5m and the 4.25m setbacks and said that such a setback would result in an unusable space. The size of the deck resulting from the 4 alternate setbacks was also drawn on plan to enable the Court to visualise the impact on useable space. Mr Goldsmith's evidence is that with steep topography and views to the water, it is not unusual and generally accepted to have a certain degree of mutual overlooking is acceptable and that a 2m setback achieved an appropriate balance of privacy and amenity for both the site and the adjoining property at the northeast.
36 In his opinion, the existing building in its landscape setting sits comfortably within the local setting and therefore the desired future character is retained and the bulk and scale of the built form remains the same.
Applicant's statement and photographs.
37 I have read the applicant's statement and note that she explains the reasons why she has applied for approval of the deck. I accept her evidence as to a need for pool access and a useable private open space. However, I reject as justification for the approval of this application the fact that a previous deck has been demolished. While I understand that it was demolished because it was collapsing, that fact is not relevant in an assessment of this application under section 79C of the Act.
Findings
38 I accept council's submission that the correct approach to this application is a determination under s 80 of the Act; subject to a consideration of relevant matters required by s 79C(1) of the Act. Relevantly in this case, the DCP has to be treated as a fundamental element in or focal point of the decision making process: Zhang In saying that, I appreciate that the provisions of the DCP are not mandatory and in the particular circumstances of the case, it is justified to vary the provisions where the underlying objective is achieved without numerical compliance with the control.
39 This is not an application to rebuild a pre-existing deck. I do not believe that the purported building approval for the demolished deck or photographs of the previous deck are a relevant consideration under s 79C(e) and I reject the applicant's submission that it is in the public interest to have regard to that fact, because to do otherwise will affect the lodgement of DAs for pre-existing structures because there will be no certainty of an approval. Each case must be considered on its own facts and a development application needs to be assessed according to the law having regard to the relevant matters in s 79C(1).
40 I accept the evidence of Mr Goldsmith that the particular constraints of this site including the steep topography, existing built form and existing limited open space and the orientation of the view mean that it is unreasonable to require a setback of 6.5m from the rear boundary on this site. I accept his expert assessment that this would result in an unusable deck.
41 I accept that the DCP control for site coverage for the site cannot be achieved because the existing built form exceeds the site coverage control. However in the circumstances of this case, the construction of the deck with a rear boundary setback of 2m would not significantly increase the site coverage on this site. I do not accept council's evidence that this deck should not be approved because it increases the already non complying site coverage. The evidence does not support a finding that the elevated deck will be perceived as a bulky addition to the built form on this site. I accept Mr Goldsmith's evidence that with appropriate landscaping in the 2m setback area and in the undercroft of the elevated deck that the outcomes of the controls in the DCP for setback and site coverage will be satisfactorily achieved. The evidence supports a finding that a variation of the setback and site coverage controls is justified in the circumstances of this case. The setback control in cl D12.6 to minimise bulk and scale of the built form will be achieved by the landscaping conditions and the 2m rear boundary setback. The condition to retain vegetation that exists and provide for more landscape screening will achieve the outcome of visually reducing the built form from the objectors' rear yard.
42 The condition about stormwater runoff will achieve the outcome in cl D12. 10 site coverage for environmentally sensitive land by minimising runoff and assist with stormwater management and address the objectors' concern.
43 I accept the view expressed by Mr Goldsmith that with steep topography and views to the water it is not unusual to have a certain degree of mutual overlooking. The question is the reasonableness of the extent of the overlooking in the particular circumstances of the case where houses and entertaining areas are focussed to the view and the sharing of the view. Mr Goldsmith's evidence about the landscaping and its ability to achieve the outcomes of the DCP provisions is supported by his sight line drawing which demonstrates a 2m setback from the rear boundary will not create unreasonable overlooking of the objector's property from the deck. I accept the applicant's evidence that the open space on the deck will have good solar access and provide useable private open space for the enjoyment of the occupants well as. It achieves the outcomes in cl C12.7 of the DCP in respect of usable private open space.
44 Based on the evidence, I am satisfied on the facts of this case that a variation of the DCP 21 setback and site coverage controls is justified. Furthermore, I am satisfied on an assessment under 79C of the Act that the objectors' concerns about privacy and overlooking from the deck to their property, and the integrity of the retaining wall on the boundary are adequately dealt with by the agreed conditions which include the requirement that the deck be setback 2m from the rear north eastern boundary with appropriate landscaping.
45 Accordingly, the Court makes the following orders.
1. The appeal is upheld.
2. Development consent to DA417/09 is granted subject to the conditions that are annexure A to this judgment.
3. The exhibits apart from exhibit 2 and exhibit 1(the plans) are returned to the parties.
