(e) Institutional lands<br />

5.10 A considerable amount of developable land <strong>in</strong> suburban locations is<br />

<strong>in</strong> <strong>in</strong>stitutional use and/or ownership. Such lands are often<br />

characterised by large build<strong>in</strong>gs set <strong>in</strong> substantial open lands which<br />

<strong>in</strong> some cases may offer a necessary recreational or amenity open<br />

space opportunity required by the wider community. In the event that<br />

plann<strong>in</strong>g authorities permit the development of such lands for<br />

residential purposes, it should then be an objective to reta<strong>in</strong> some of<br />

the open character of the lands, but this should be assessed <strong>in</strong> the<br />

context of the quality and provision of exist<strong>in</strong>g or proposed open<br />

space <strong>in</strong> the area generally. In the development of such lands, average<br />

net densities at least <strong>in</strong> the range of 35-50 dwell<strong>in</strong>gs per hectare<br />

should prevail and the objective of reta<strong>in</strong><strong>in</strong>g the open character of the<br />

lands achieved by concentrat<strong>in</strong>g <strong>in</strong>creased densities <strong>in</strong> selected parts<br />

(say up to 70 dph). The preparation of local area plans sett<strong>in</strong>g out<br />

targets for density yields, recreational uses and urban form should be<br />

considered <strong>in</strong> advance of development. In the absence of an LAP, any<br />

application for development of <strong>in</strong>stitutional lands should be<br />

accompanied by a masterplan outl<strong>in</strong><strong>in</strong>g proposals for the entire<br />

landhold<strong>in</strong>g.<br />

(f) Outer Suburban / ‘Greenfield’ sites<br />

5.11 These may be def<strong>in</strong>ed as open lands on the periphery of cities or<br />

larger towns whose development will require the provision of new<br />

<strong>in</strong>frastructure, roads, sewers and ancillary social and commercial<br />

facilities, schools, shops, employment and community facilities.<br />

Studies have <strong>in</strong>dicated that whilst the land take of the ancillary<br />

facilities rema<strong>in</strong>s relatively constant, the greatest efficiency <strong>in</strong> land<br />

usage on such lands will be achieved by provid<strong>in</strong>g net residential<br />

densities <strong>in</strong> the general range of 35-50 dwell<strong>in</strong>gs per hectare and such<br />

densities (<strong>in</strong>volv<strong>in</strong>g a variety of hous<strong>in</strong>g types where possible)<br />

should be encouraged generally. <strong>Development</strong> at net densities less<br />

than 30 dwell<strong>in</strong>gs per hectare should generally be discouraged <strong>in</strong> the<br />

<strong>in</strong>terests of land efficiency, particularly on sites <strong>in</strong> excess of 0.5<br />

hectares.<br />
