    THE LAND AND
    ENVIRONMENT COURT
    OF NEW SOUTH WALES

    Watts C

    19 October 2004

    10164 of 2004 – Sam Wu v Ku-ring-gai Council

    JUDGMENT

    1 This is an appeal under s 97 of the Environmental Planning and Assessment Act 1979, against the deemed refusal by Ku-ring-gai Council (the council) of an integrated development application to demolish the existing dwelling on the land and to erect a detached dual occupancy development at Lot A DP 365652, being No 27 Bent Street, Lindfield. The council subsequently formally refused the application and then sought to enter into consent orders.
    2 I visited the land in company with the parties on the day of the on-site hearing.
    3 I have concluded that when considered under s 97 of the Environmental Planning and Assessment Act 1979 the application as conditioned would be satisfactory and such as may be consented to by the Court.

    The land
    4 The battleaxe shaped land is situated on the northwestern side of Bent Street near its intersection with Woodland Lane. Excluding the area of the axe handle it is largely rectangular with dimensions of 45.269m x 31.295m giving an area, excluding that axe handle, of 1,440m2. Including the axe handle the land has an area of some 1,902.42m2.
    5 The land abuts a natural watercourse that traverses Nos 25 and 29 Bent Street, Lindfield. This watercourse is piped under the driveway of the subject land. There is a fall of 1m to 2.5m across the site from north-west to north-east. A large (level) natural rock outcrop is situated towards the rear of the land, and may be observed above the natural surface of the ground in the north-west corner. Around the perimeter of the land are thirteen (13) mature trees including a significant Angophora costata (Sydney Redgum) near the north western (rear) site boundary and a mature Eucalyptus pilularis (Blackbutt) and Eucalyptus piperita (Sydney Peppermint) near the southeastern boundary.
    6 Three drainage easements affect the land. One easement is located along the northeastern boundary and the other two cross the access handle. Both are piped where they crosses the driveway.
    7 Erected on the land is a single-storey brick and tile dwelling with a detached garage.
    8 The Ku-ring-gai Visual Character Study locates the land within an area characterised by single dwellings on single lots with most construction being from the period between 1920-1945. A mix of architectural styles and periods are evident within the streetscape. Development within Bent Street comprises of residential dwellings.
    9 A school abuts the northwestern boundary of the land and adjoining residential properties are of single-storey and two-storey storey height. The Lindfield shopping area and Lindfield railway station are situated about 500m to the north-west.

    Relevant planning controls

    Rivers and Foreshore Improvement Act 1948, (RFI Act)
    10 The RFI Act was gazetted 21 May 1948 and since has been amended. Part 3A of the RFI Act relates to the protection of rivers and lakes.
    11 Under Part 3A: 22A Definitions.

        In this Part:
            ‘Constructing Authority’, when used in connection with protected waters or land under or adjacent to protected waters, means:
    (a) if the bed of the waters is vested in the Waterways Authority or a Port Corporation (within the meaning of the Ports Corporatisation and Waterways Management Act 1995 ) the Minister for Ports, or
    (b) if the waters are tidal and paragraph (a) does not apply the Minister for Public Works, or
    (c) in any other case the Ministerial Corporation.
            ‘make an excavation’ includes cause or allow an excavation to be made.
            ‘material’ means any part of the surface of any land or any matter lying beneath that surface.
            ‘permit’ means a permit in force under this Part.
            ‘protected land’ means:
    (a) land that is the bank, shore or bed of protected waters, or
    (b) land that is not more than 40 metres from the top of the bank or shore of protected waters (measured horizontally from the top of the bank or shore), or
    (c) material at any time deposited, naturally or otherwise and whether or not in layers, on or under land referred to in paragraph (a) or (b).
            ‘protected waters’ means a river, lake into or from which a river flows, coastal lake or lagoon (including any permanent or temporary channel between a coastal lake or lagoon and the sea).
            ‘remove material’ includes cause or allow material to be removed.

    12 A s 22B Permit is required for excavation etc.
    (1) A person must not:
    (a) make an excavation on, in or under protected land, or
    (b) remove material from protected land, or
    (c) do anything which obstructs, or detrimentally affects, the flow of protected waters, or which is likely to do so,
          unless the person is either authorised to do so by a permit under this Part and does so in accordance with any conditions to which the permit is subject, or is authorised to do so by the regulations.

    (2) A person who contravenes subsection (1) is guilty of an offence and is liable:
    (a) in the case of a corporation to a penalty not exceeding 1,250 penalty units and, in the case of a continuing offence, to a further penalty not exceeding 600 penalty units for each day the offence continues, or
    (b) in the case of an individual to a penalty not exceeding 600 penalty units and, in the case of a continuing offence, to a further penalty not exceeding 300 penalty units for each day the offence continues.
    (3) It is a defence to any proceedings against a person in respect of a contravention of subsection (1) for the person to establish:
    (a) that the commission of the offence was due to causes over which the person had no control and that the person took reasonable precautions and exercised due diligence to prevent the commission of the offence, or
    (b) in the case of proceedings for a contravention of subsection (1)(c), that the person could not reasonably have foreseen that the person’s actions would result in, or in the likelihood of, the obstruction or detrimental effect concerned.
    (4) A person does not commit an offence under subsection (1) if the activity concerned relates to a work, or class of work, specified by the Ministerial Corporation by order published in the Gazette.

    13 Under s 22C a permit may be granted:
    1. Application for a permit is:
    (a) to be made to the Constructing Authority in the form approved by the Authority, and
    (b) to be accompanied by the fee determined by the Authority.
    (2) As a pre-condition to the grant of a permit, the Constructing Authority may require the applicant to give security for the due performance of the applicant’s obligations under and in connection with the permit for an amount, in a form and on such terms and conditions as the Constructing Authority may require.
    (3) The Constructing Authority may, after any investigation it thinks necessary, refuse a permit or grant one subject to such conditions as it thinks appropriate.
          (3A) The issue of a permit in relation to integrated development within the meaning of section 91 of the Environmental Planning and Assessment Act 1979 is subject to Division 5 of Part 4 of that Act.
    14 The proposed development is located within 40m of ‘protected waters’ being an existing watercourse and thus the application is integrated under Part 3A of the RFI Act. General Terms of Approval, (GTA) have been issued by the Department of Infrastructure, Planning and Natural Resources, (DIPNR) [Note: Exhibit 1 Tab 9] and incorporated in conditions agreed between the parties.

    State Environmental Planning Policy No 53 - Metropolitan Residential Development, (SEPP53)
    15 Under s 3(1) of SEPP53 the aims are to encourage the provision of housing in metropolitan areas that will:
    (a) broaden the choice of building types and locations available in the housing market, and
    (b) make more efficient use of existing infrastructure and services, and
    (c) reduce the consumption of land for housing and associated urban development on the urban fringe, and
    (d) be of good design.


      (2) These aims are to be achieved:
    (a) by establishing planning controls that will provide opportunities for a variety of housing types, such as multi unit housing or multi unit housing combined with development for any other purpose to be developed in areas the councils of which have not adopted residential development strategies approved by the Minister, and
    (b) by setting out design principles that, if followed, will achieve built form that responds to the characteristics of its site and location, and
    (c) by encouraging councils to prepare and adopt residential development strategies and supporting local environmental plans and policies that will achieve those aims, and by allowing local government areas to be exempted from the whole or parts of this policy when those strategies and plans are in place.
      (3) In addition, this Policy aims to simplify and streamline certain aspects of the planning system relating to residential development:
    (a) by revising the provisions in a number of State environmental planning instruments to improve their operation, and
    (b) by restating the revised provisions of those environmental planning instruments in a single policy written in a manner that is easy to understand.

    16 Part 3 of SEPP53 applies to dual occupancy development and cl 15 sets out the objectives of this Part:
    (a) to create opportunities for two dwellings to be developed on a single allotment of land, and
    (b) through the other provisions of this Policy, to ensure that dual occupancy development is:
    i. designed and assessed with a full understanding of the opportunities and constraints of each site, and
    ii. designed and assessed having adequate regard for the design principles contained in Part 5.

    17 The proposed detached dual occupancy development is permissible under cll 16 & 17 of SEPP53.
    18 Part 3 of SEPP53 applies to land zoned Residential 2(b) in Ku-ring-gai.
    19 Clause 16(1) of SEPP53, states:
        This part applies to all land to which this Policy applies that is within a residential zone under another environmental planning instrument.
    20 Clause 17 of SEPP53, states:
        This part allows development that results in two dwellings being located on the one allotment of land if the land is within a zone, which, under another environmental planning instrument, permits the erection of dwelling houses.
    Ku-ring-gai Planning Scheme Ordinance, (KPSO)
    21 When the application was lodged the land was zoned 2(b) Residential under the KPSO and under the land use table to cl 23, dwelling houses are permissible as Column 1 uses, with consent. However, all forms of multi-dwelling development are prohibited. The Environmental Planning and Assessment Act 1979 was amended in 1998 to require consent for all forms of residential development including dwelling houses.
    22 Although not relevant to the present applications under SEPP53, the general aims for residential zones as set out in Sch 9 of the KPSO are:
        To maintain and where appropriate, improve the existing amenity and environmental character of Residential zones; and
        To permit new residential development where it is compatible with the existing environmental character of the locality and has a sympathetic and harmonious relationship with adjoining development.
    23 Clause 46(2) of the KPSO provides a maximum height for residential development of 8m.
    24 Clause 58A of the KPSO requires consent to be obtained for subdivision. Clause 58B(5) of the KPSO stipulates that the subdivision standards do not apply to approved dual occupancies.
    25 Clause 60C of the KPSO provides that the maximum built upon area of land is 60%.
    26 The land is now zoned Residential 2(c2) under Interim Development Order 194, (IDO194) made early in 2004 and if the application were submitted under that instrument it would be prohibited. However, there was a savings clause included in that instrument under which this application is made.

    Development Control Plan 40, (DCP40)
    27 DCP40 would be overridden by SEPP53 and relates to waste management. A waste management plan was submitted and there was no issue between the parties.

    Development Control Plan 43, (DCP43)
    28 DCP43 relates to car parking. DCP43 would be overridden by SEPP53 and the proposal exceeds those requirements and there was no issue between the parties.

    Council's Dual Occupancy Control Code, (Code)
    29 The Code was adopted in April 2003 and contains sections relating to stormwater management (Section 4.5), privacy (Section 4.3), Car Parking and Accessibility (Section 4.7). In relation to stormwater, the Code reflects Council's Stormwater Management Manual that states:

        The construction of any permanent structure (such as dwellings, garages, impervious fences, pools) or the placement of fill over a watercourse, drainage depression, piped drainage system or within the path of the 100 year flood is generally not permitted.
        A natural bushland and riparian zone of a minimum width of either 10 metres (or as otherwise specified by Council) on either side of the top of the bank of a non perennial watercourse or the 100 year flood zone as calculated by a consulting engineer, whichever is the greater, is not to be subject to development without consent of the council.
    30 The applicant is prepared to landscape the riparian zone with native indigenous species and abide by the GTA’s provided by DIPNR and as a result the proposal would now satisfy the council’s requirements in this regard.

    The proposal and its history
    31 Integrated development application No 1559/03 was lodged with the respondent council on 28 November 2003 to demolish the existing dwelling on the land and to erect a detached dual occupancy development on the land. Each detached dwelling would be two-storeys in height and each would comprise living areas on ground floor level with four (4) or (5) (Dwelling No 2) bedrooms proposed on the first floor. A triple garage was originally proposed (now a double garage) for Dwelling No 1 (Wu residence) and a double garage is proposed for the second dwelling (Yang Residence). A swimming pool set in landscaped gardens was originally proposed for each dwelling and is now deleted.
    32 Each dwelling would be around 6.4m in height measured from natural ground level to the ceilings of the upper floors with a maximum overall height of about 9.5m to the roof ridges.
    33 The floor space ratio (F.S.R) would be around 0.47:1.
    34 The proposed setbacks for Dwelling No 1 (Wu residence) would be 5.5m to the northwestern boundary, 3.022m to the northeastern boundary, 8.611m to the southeastern boundary, with a 6.428m separation between the dual occupancies.
    35 The proposed setbacks for Dwelling No 2 (Yang residence) would be 3.972m to the northwestern boundary, 3m to the southwestern boundary and 7.181m to the southeastern boundary. Although no survey plan was supplied to the Court, it would appear from the position of the white corner survey mark, seen on the site inspection, that the southern corner of the property would be around 3m from the stream edge. This would suggest that the southern corner of the proposed garage of the Yang residence would be around 10m from the stream bank and elevated above it.
    36 A landscape plan and a statement of environmental effect accompanied the application.

    Notification
    37 The application was notified on 2 December 2003 to nearby owners and occupants and the council received five (5) letters of objection.
    38 At a meeting with the applicant on 4 March 2004 the council requested additional information be submitted and this was confirmed in writing. The council’s reporting officer recommended that as insufficient information was available for assessment of the application it should remain undetermined.

    Amendments to the proposal
    39 By letter dated 27 August 2004, Mr Minto, consultant town planning for the applicant, addressed the issues of stormwater, traffic, existing trees, rock shelf, landscape plan, and concluded that the council’s concerns have now been satisfied. The triple garage for the Wu residence was reduced to a double garage.

    The council’s decision
    40 When the appeal was filed the council had not determined the application. The matter comes before the Court as a deemed refusal.

    The hearing
    41 The appeal was filed on 13 February 2004.
    42 Mr C Swanepoel, town planner, assessed the development application on behalf of the respondent council and was involved in discussions with the applicant.
    43 Mr A Minto, consultant town planner was involved in advising the applicant on planning matters.
    44 Also present at the on-site hearing were:
    · Mrs Julie Harrington, resident of No 29 Bent Street, Lindfield; who was concerned in relation to stormwater and fencing;
    · Mrs Jennifer Wilson, resident of No 33 Bent Street, Lindfield, who was concerned about stormwater, protection of trees and the reason for the council’s change of mind;
    · Mrs Susan Howard, resident of No 35 Bent Street, Lindfield, who was interested in stormwater matters.

    The issues
    43 On 2 April 2004 the council filed an amended statement of issues:
    1. Site analysis: Whether the site analysis prepared meets the requirements of clause 31 of the State Environmental Planning Policy No. 53 - Metropolitan Residential Development, (SEPP 53) and, if it does not meet those requirements, whether consent can be granted to the proposed development.

    2. Visual Impacts: Whether the proposed development is inconsistent with Clause 32(h) of SEPP 53 in that it will result in significant visual bulk impacts to the locality and adjoining properties.
              Particulars:

    i. Insufficient setbacks are provided to enable screen planting along the south-western (side), north-eastern (side) and north-western (rear) boundaries adjoining the proposal to soften such impacts.
    ii. Whether the siting and design of the proposed development would maintain the existing amenity and environmental character of the residential zone (clause 1(a) of schedule 9).
    iii. Whether the siting and design of the proposed development would be incompatible with the environmental character of the locality and would not have a sympathetic or harmonious relationship with adjoining properties (clause 1(b) of schedule 9).

    3. Access: Whether the proposal is inconsistent with Clause 32(f) of SEPP 53 in providing convenient, obvious and safe access for pedestrians and motorists and whether convenient access and parking for residents and visitors is proposed.
              Particulars:

    i. The application has failed to provide sufficient information to enable an assessment of the adequacy of the proposed driveway and manoeuvring areas for the proposed development.
    ii. The proposed driveway layout fails to demonstrate the requirements of AS2890.1 - 2004 (Off street car parking) having regard to suitable driveway gradients.
    iii. The proposed driveway layout fails to demonstrate the requirements of AS2890.1 - 2004 (Off street car parking) having regard to provision adequate on site manoeuvring areas.


    iv. The proposed driveway layout fails to demonstrate the requirements of AS2890.1 - 2004 (Off street car parking) having regard to provision of a suitable passing bay.

    4. Stormwater and hydrology: Whether the proposal is inconsistent with Clause 32(d) of SEPP 53 in controlling and minimising the disturbance and impacts of stormwater and whether it has been designed with regard to the scope for on site infiltration of water.
              Particulars

    i. The application has failed to provide sufficient information (ie. flood study/drainage documentation) to enable an assessment of the adequacy of the proposed stormwater drainage and hydrology impacts on site.
    ii. Whether the proposed development will alter the passage of overland flows and will result in adverse impacts upon the subject site and adjoining properties.
    iii. Whether the subject property has the right to drain into the easement over all downstream properties
    iv. Whether the proposed riparian setback zone associated with the adjoining creek is sufficient and will not lead to immediate and/or ongoing impact on the overall environmental integrity of the creek.

    5. Loss of trees: Whether the proposed development will result in adverse impacts upon the existing vegetation and trees on the site and therefore be inconsistent with the objectives set out in clause 15 of SEPP 53.
              Particulars:

    i. The proposed development will result in adverse impacts to the following trees: Angophora Costata (Sydney Redgum) located adjacent to the north-western (rear) site boundary.
    ii. Eucalyptus pilularis (Blackbutt) located adjacent to the driveway areas on the south-eastern boundary.

    6. Council's Dual Occupancy Development Policy: Whether the proposed development has regard for the aims and objectives of Council's Dual Occupancy Development policy.
              Particulars:
              Whether the proposed development meets the requirements of Council's Dual Occupancy Development policy in relation to built upon area, floor space ratio, setbacks, tree retention and provision of suitable landscaping.

    44 The following emerged as the salient issues:
    · Stormwater and hydrology; and
    · Ground water replenishment around trees along the southeastern boundary.

    The evidence and findings

    Stormwater and hydrology
    45 The applicant agreed that the necessary stormwater easements would be put in place prior to development taking place. This was conditioned to require an extension of the ‘roof water’ easement passing though No 29 Bent Street to the natural watercourse to the southwest. The adjoining neighbour Mrs J Harrington, of that adjoining property (No 29 Bent Street, Lindfield), was present at the on-site hearing and was content to meet with the applicant’s representatives with a view to arranging for the legal easement to be extended and amended at the applicant’s cost.
    46 I am satisfied that such a condition would permit the necessary legal requirements to be put in place to enable stormwater from the land to be carried to the natural watercourse.

    Ground water replenishment around trees along the southeastern boundary
    47 The applicant was content to include a condition that would ensure that groundwater infiltrated the area around the existing trees along the southeastern boundary adjacent the creek line. This might include works in addition to the proposed stormwater detention tanks.
    48 I am satisfied that an appropriate condition would resolve that matter.

    Other issues
    49 Other issues have been resolved through discussion between the parties and local residents and amendments of the plans.
    50 One issue raised by Mrs J Wilson, of No 33 Bent Street, Lindfield, was the physical presence of the proposed Dwelling No 2 (Yang residence) close the rear boundary of her property and 7.181m from the common boundary. In response to her comments, the applicant agreed to extend the row of Melaleuca gibbosa (Dwarf Purple Bottlebrushes) shown on the Landscape Concept Plan in Exhibit B to the southwestern boundary. These trees, would according to the Landscape Concept Plan, mature to a height of around 2m and I am satisfied, would assist in screening from view to the south, of the garage wall of the Yang residence. I am satisfied this, in combination with retention and augmentation of the native vegetation on the northwestern bank of the creek, would sufficiently ameliorate the impact of the proposal when viewed from Mrs Wilson’s property.
    51 As agreed between the parties and for the above reasons, the appeal may be upheld.

    Conditions
    52 The conditions are those in Exhibit 4 as amended during the on-site hearing.

    Orders
    53 The consent orders are:
    1. The appeal under s 97 of the Environmental Planning and Assessment Act 1979 is upheld.

    2. Integrated development application No 1559/03 lodged with the respondent council on 28 November 2003 to demolish the existing dwelling on the land and to erect a detached dual occupancy development at Lot A DP 365652, being No 27 Bent Street, Lindfield, is approved subject to Conditions 1 to 81 in Annexure A.

    3. The exhibits are retained.
