(2D) Despite subclause (2), development on land that has a maximum building height of 8.5 metres shown for that land on the Height of Buildings Map may exceed a height of 8.5 metres, but not be more than 10.0 metres if:
(a) the consent authority is satisfied that the portion of the building above the maximum height shown for that land on the Height of Buildings Map is minor, and
(b) the objectives of this clause are achieved, and
(c) the building footprint is situated on a slope that is in excess of 16.7 degrees (that is, 30%), and
(d) the buildings are sited and designed to take into account the slope of the land to minimise the need for cut and fill by designs that allow the building to step down the slope.
(2E) Despite subclause (2), development for the purposes of shop top housing on land identified as "Area 5" on the Height of Buildings Map may have a height of up to 10 metres if the top floor of the building is setback a minimum of 6 metres from the boundary to the primary street frontage.
(2F) Despite subclause (2), development on land identified as "Area 6" on the Height of Buildings Map must not exceed 8.5 metres at the street frontage.
(2G) In this clause:
flood planning level means the level of a 1:100 ARI (average recurrent interval) flood event plus 0.5 metres freeboard, or other freeboard determined by an adopted floodplain risk management plan.
floodplain risk management plan has the same meaning as it has in the Floodplain Development Manual (ISBN 0 7347 5476 0), published in 2005 by the NSW Government.

4.4 Floor space ratio
(1) The objectives of this clause are as follows:
(a) to ensure that buildings, by virtue of their bulk and scale, are consistent with the desired character of the locality,
(b) to minimise adverse environmental effects on the use and enjoyment of adjoining properties and the public domain,
(c) to minimise any overshadowing and loss of privacy to neighbouring properties and to reduce the visual impact of any development,
(d) to maximise solar access and amenity for public places,
(e) to minimise the adverse impact of development on the natural environment, heritage conservation areas and heritage items,
(f) to manage the visual impact of development when viewed from public places, including waterways,
(g) to allow for the reasonable sharing of views.
(2) The maximum floor space ratio for a building on any land is not to exceed the floor space ratio shown for the land on the Floor Space Ratio Map.
4.5 Calculation of floor space ratio and site area
(1) Objectives
The objectives of this clause are as follows:
(a) to define floor space ratio,
(b) to set out rules for the calculation of the site area of development for the purpose of applying permitted floor space ratios, including rules to:
(i) prevent the inclusion in the site area of an area that has no significant development being carried out on it, and
(ii) prevent the inclusion in the site area of an area that has already been included as part of a site area to maximise floor space area in another building, and
(iii) require community land and public places to be dealt with separately.
(2) Definition of "floor space ratio"
The floor space ratio of buildings on a site is the ratio of the gross floor area of all buildings within the site to the site area.
(3) Site area
In determining the site area of proposed development for the purpose of applying a floor space ratio, the site area is taken to be:
(a) if the proposed development is to be carried out on only one lot, the area of that lot, or
(b) if the proposed development is to be carried out on 2 or more lots, the area of any lot on which the development is proposed to be carried out that has at least one common boundary with another lot on which the development is being carried out.
In addition, subclauses (4)-(7) apply to the calculation of site area for the purposes of applying a floor space ratio to proposed development.
(4) Exclusions from site area
The following land must be excluded from the site area:
(a) land on which the proposed development is prohibited, whether under this Plan or any other law,
(b) community land or a public place (except as provided by subclause (7)).
(5) Strata subdivisions
The area of a lot that is wholly or partly on top of another or others in a strata subdivision is to be included in the calculation of the site area only to the extent that it does not overlap with another lot already included in the site area calculation.
(6) Only significant development to be included
The site area for proposed development must not include a lot additional to a lot or lots on which the development is being carried out unless the proposed development includes significant development on that additional lot.
…
(8) Existing buildings
The gross floor area of any existing or proposed buildings within the vertical projection (above or below ground) of the boundaries of a site is to be included in the calculation of the total floor space for the purposes of applying a floor space ratio, whether or not the proposed development relates to all of the buildings.

4.5A Density controls for certain residential accommodation
(1) The objectives of this clause are as follows:
(a) to achieve planned residential density in certain zones,
(b) to ensure building density is consistent with the desired character of the locality.
(2) Development consent must not be granted to development for a purpose specified in Column 1 of the table to this clause on land in the zone shown opposite that development in Column 2 of that table unless the development complies with the density requirements specified in Column 3 of that table.
(3) This clause does not apply to land in the Warriewood Valley Release Area.
(4) In this clause:
Warriewood Valley Release Area means the area identified as Warriewood Valley Release Area on the Urban Release Area Map.
