Maintenance Schedule
A Maintenance Schedule is required to detail the specified time periods and work required for routine
maintenance over a period of a year once the landscaping has been established. The Maintenance
Schedule should outline requirements and details of pruning, trimming, weeding, re-mulching and
restructuring of plants.
Minimum Design Requirements for Development
Outlined below are the minimum design requirements for any development proposed in the Douglas
Shire. These requirements should be read in conjunction with the Landscaping Code and the
Performance Criteria and Acceptable Solutions of the particular Planning Area and Locality and, if
relevant, the applicable Land Use Code.
•
Wherever possible, existing native vegetation on site is to be retained, incorporated into the site
design and protected during works. Mature vegetation on site is retained wherever possible to
provide shade and screening from adjoining properties, and enhance the new development.
•
Existing native plant species characteristic of the area are to be included in the landscape
design.
•
Landscaping is to provide a buffer or screening between adjoining developments with dense
planting, with consideration given to location of window openings, private open space and
service areas, such as bin enclosures.
•
Dense planting is to be used, with the three tier approach of trees, shrubs and groundcovers.
Densities are to be as follows:
-
Trees up to 3 metre centres in landscape buffer/screen planting areas and up to 6 metres in
other areas;
-
Shrubs up to 1.5 metre centres; and
-
Groundcovers up to 0.6 metre centres.
•
Plant selection is to be in accordance with the requirements of each Locality, or otherwise set
out below specifically for the following Localities:
-
Mossman and Environs: 60% of the total proposed species are endemic or native species.
-
Port Douglas and Environs: 60% of the total proposed species are endemic or native
species.
-
Coastal Suburbs, Villages and Townships: 60% of the total proposed species are endemic
or native species.
And in all Localities 75% of dense planting is to be endemic or native species, and palms used
as accent plants only unless a greater percentage is specified in the Locality Code.

•
Reticulated irrigation systems are to be in accordance with Australian Standards.
•
Soil preparation is to be in accordance with landscaping best practice, including high quality
soil mix, slow release fertiliser or manure and high quality mulch.
Minimum Design Requirements for Reconfiguring a Lot
Existing Native Vegetation
Existing on site native vegetation should be taken into account in the reconfiguration design and
wherever possible should be retained. Native vegetation significantly enhances the character and
visual appeal of an area as well as providing an established habitat for local wildlife. The root system
of existing vegetation to be retained on site during development should be protected as much as
possible to the drip system and by a root curtain or sheet piling.
The designation of parkland should incorporate stands of existing native vegetation in order to
preserve the vegetation and improve the amenity of the area.
Viewscapes
Views are an important feature within any proposed development. A reconfiguration layout should
maximise the opportunities presented by the natural setting. This may be achieved by:
•
preserving existing views;
•
enhancing existing views eg. by screen planting to screen adjacent buildings;
•
creating views into and out of the subdivision eg. by tree planting to frame vistas, by removing
unwanted structures;
•
encouraging viewing areas, and providing for connectivity using bike paths/walking trails.
Street Tree Planting
Shaded, tree lined streets can significantly add to the amenity of an area, for example:
•
an individual character may be achieved by using a specific tree species for each street;
•
create and reduce heat and glare from the road pavement;
•
provide shade for parked cars during the summer months;
•
native flowering trees can provide a source of food and shelter for insects, birds and animals.
It is the Council’s intention to promote the value of the streetscape by ensuring that street trees are
planted as part of the development process. In order to ensure a well balanced workable, and low
maintenance landscape, all street tree planting should conform to the minimum standards listed
below:
August, 2006
Page 52
Species, Selection and Size
An avenue of trees of identical species and size planted at regular intervals has far greater visual and
aesthetic impact than a mismatched selection of incompatible trees. In order to promote continuity in
new streetscapes, a single species should be nominated for each street. Where a development is
occurring in an established street setting, an assessment of the existing street trees should be made,
and the most prevalent, healthy and appropriate species chosen for footpath planting.
Tree species should be selected for their suitability to the site conditions eg. small trees under power
lines, drought resistance, soil suitability, refer to the Plant Species Schedule.
To ensure consistency in growth rate and form all new street trees are to be no less than 2 metres in
height and should be well established in their root and branch formation. A minimum 25 litre
container should ensure a good survival factor.
Alignment and Placement
•
Tree canopies at maturity are not to be within 4.0 metres of electricity or telephone poles or
pillars.
•
Tree canopies at maturity are not to be within 7.5 metres of street lights, to ensure effective
street lighting.
•
Tree canopies at maturity are not to be within a 4 metres radius of high voltage transmission
lines.
•
Trees are to be planted at 5 metre centres under power lines and generally 8-12 metres
elsewhere to achieve an effective design.
•
Trees are to be placed a minimum of 600 mm and a maximum of 1000 mm from the back of
kerbs.
•
Trees are to be placed a minimum of 3 metres from any driveway.
•
At intersections, trees are to be placed a minimum of 10 metres back from the face of the kerb
of the adjoining street.
•
Trees are to be located so as not to obstruct access to any services or signage.
•
Trees are to be located so as not to obstruct pedestrian or vehicular traffic, nor create a traffic
hazard or cause damage to existing trees.
•
Trees are not to be within 2 metres of a side entrance stormwater pit.

Landscape Zones in the Douglas Shire
The Douglas Shire can be separated into three distinct landscape zones based on natural vegetation
associations of a similar visual character. There is no precise delineation between zones and an
individual assessment of each site in the vicinity of the boundaries between zones should be made.
The zones are:
Port Douglas and Coastal Communities
The areas of Port Douglas and the coastal communities have their own unique landscape identities,
with a mix of coastal and eucalyptus vegetation, melaleuca swamp communities as well as altered
landscapes surrounding existing residential and tourist developments, comprising of endemic, native
and exotic species. This area incorporates Port Douglas, Oak Beach, Cooya Beach, Newell Beach,
Wonga Beach and Wangetti.
Mossman to Daintree
This area is characterised by closed forest types (rainforest) on heavier clay loam soils to the west of
the coastal communities. The area incorporates rainforest, riparian forest (vegetation along creeks)
and regrowth forest.
North of the Daintree River to the Bloomfield River
This area is characterised by closed forest occurring on a variety of soil types and incorporates Cape
Kimberley, Cow Bay, Cape Tribulation and areas to the east and west of Cape Tribulation Road.
Plant Species Schedule
The Plant Species Schedule provides a list of endemic and native species suitable for use in
landscaping projects in each of the Landscape Zones. The street tree list also identifies street trees for
use in the Douglas Shire.
In preparing Landscape Concept Plans and final Landscape Plans, selections from the Plant Species
Schedule can be supplemented by other species. For more information regarding species selection
consult the Parks and Gardens Section of the Douglas Shire Council.
