6 Clause 30 of the LEP provides that:
30 When assessing the impact of residential land uses proposed in the residential zones by development applications and whether those uses satisfy the objectives of the zone concerned, the consent authority must take into consideration the following matters and must not grant consent unless it is satisfied that those matters have been adequately addressed by relevant documentation submitted to it:
(a) the impact that the proposed development may have on adjoining development, buildings and open space from loss of sunlight, views and privacy,
(b) the effect of the proposed development on the quality of the streetscape,
(c) the cumulative impact of successive developments on the general character of the neighbourhood
(d) the impact of the proposed development on adjoining properties in terms of size, bulk, height and amount of landscaped area,
(e) the retention and enhancement of existing vegetation,
(f) any adverse impact on the natural and built environment,
(g) the location of the proposed development in relation to potential risks, including flooding, bushfire and other hazards,
(h) the impact that the proposed development may have on any public area or water body from loss of sunlight, views and visual amenity.
7 Clause 34 of the LEP deals with building height in residential zones as follows:
34(1) The objectives of the height limits are to:
(a) achieve consistency in the scale of buildings within each zone, and
(b) minimise adverse impacts from development on adjoining or nearby properties due to loss of privacy and views, and overshadowing, and
(c) relate the building to the typography of the site, and
(d) …
(2) The height limits are:
(a) …
(b) before granting consent for development within the 2(c) Residential Zone, the consent authority must consider any height limit specified in the development control plan applying to the land.
(c) …
(d) …
(e) basement carparking must not exceed 1.5 m above ground level to the top of the slab.
8 Clause 35(2) of the LEP imposes a maximum floor space ratio of 1:1 for the 2(c) zone. However cl 39 (a) requires that the applicable floor space ratio for any particular site should be calculated by applying a prescribed formula to the site area. This produces an undisputed maximum floor space ratio of 0.75:1 for the site.
