1.1 What is the Public Domain Strategy ?
This Strategy has been prepared to provide those responsible for the implementation of improvements to the “Public Domain” through the Canterbury town centre redevelopment area with a coordinated set of design and material principles upon which improvement works can be developed. The strategy supports the Canterbury Town Centre Development Control Plan as the key planning policies for the redevelopment area.
The design and materials principles provide general design and materials directions upon which detailed design should be developed for individual sites.
1.2 Public Domain in Canterbury
Public Domain can be defi ned as ‘ the publicly owned and usable network of urban spaces including streets, squares, and open spaces” (South Sydney Public Domain Manual). Design for the Public Domain includes consideration of the relationship of built form (architecture) and infrastructure as signifi cant shapers and determinants of the quality of the public domain environment.
The Public Domain Principles (Section 3.0) aim to ensure that the various components that help shape urban spaces are coordinated and integrated in a manner that is sustainable, functionally effi cient, aesthetically pleasing, and safe.
1.3 Format of the Manual
The manual is arranged as described on the diagram bottom right.
1.4 Glossary of terms
The area of public domain planning and controls has a range of terms which have specifi c meaning and which have been used through this manual.
The following list identifi es the defi nitions applying to the terminology used in this document.
component identifi able aspect of the public domain to which varied function, usage, visual character, and public domain role can be identifi ed. - may include the riverwalk, streets, lanes.
DDA Disabilities Discrimination Act - identifi es requirements for equality of access for all potential users of public domain
element the items which comprise the fabric of the public domain and which may vary between public domain components - may include paving, furniture, planting.
1.5 Public Domain Management and Maintenance
Successful and enduring public domain is a function of not only design, materials, and programme of usage, but also effective maintenance and upkeep.
Key issues for ongoing management to address will include:
- ongoing establishment maintenance of all street tree plantings and planted areas (weed management, irrigation, pruning management)
- paving cleaning on street trading areas (in particular) and unit paved areas generally
- rubbish management
- programme of events for foreshore promenade
- review of design / development proposals for compliance with DCP and Public Domain Plan
It is noted that irrigation provision to landscaped areas should ideally be made through a water management system integrating stormwater harvesting or grey water recycling.

1 introduction1.6 The Canterbury Town Centre Masterplan
The arrangement of public domain spaces in Canterbury Centre is to be signifi cantly shaped and determined by the Structural Design Framework and Development Control Plan.
The Public Domain Manual builds upon these strategies in providing principles for the planning and design of public domain areas, and should be read in conjunction with these documents.
The Public Domain Strategy Plan below identifi es the proposed structure of the urban redevelopment of Canterbury Centre defi ning key components of the public domain which are referred to in this document.

2.1 GenerallyThe way in which public domain is appreciated by the community is determined by the sum of the parts which shape and comprise the public domain. Community perceptions are infl uenced by a variety of factors relating to ease and functionality of use, quality of facilities, and design and visual fabric. It is important that principles for individual components of the public domain are based on a clear understanding of the overall vision for the use and appearance of public areas.
a visionThe following vision has been identifi ed for the planning, implementation, and use of public domain in the Canterbury Centre:
“ that public domain in Canterbury facilitates community uses, activities, and experiences through development of a connected and legible framework of stimulating spaces that reinforce local and regional linkages and incorporate sustainable and coordinated design in compliment to the river front context”.
2.2 Public domain strategiesThe public domain strategies defi ne broad guiding directions that inform the development of design and materials principles, and provide an assessment benchmark for these principles (along with ongoing guideline and detailed design development) through the Canterbury Centre.
A general discussion of factors is provided, along with a proposed strategy statement, and key words which should be considered in development of planning, design and management responses.
a vision for public domain 2
Public domain in Canterbury town centre must promote an appropriate and recognisable identity and encourage use of public spaces
CANTERBURY TOWN CENTRE PUBLIC DOMAIN STRATEGY8 PRELIMINARY DECEMBER 2007
2.2.1 Character and Identity
It is essential that the public domain of Canterbury centre develop an identity that builds upon its physical, cultural, and social characteristics. The river front location of the site suggests that links to the river front and related views should be maximised. The fl ood prone nature of the foreshore suggests that generally public domain treatments should be simple and robust in design and materials.
Planning for the public domain can facilitate a balance of continuity and diversity that maintains legibility, whilst at the same time providing visual interest and differentiation where desirable.
Character of public domain in Canterbury should also refl ect the principal role of the precinct as a residential neighbourhood, and facilitate a sense of place and community.
Strategy:
Public domain development to refl ect the clear, linear grid development pattern established in the town centre masterplan, and provide a simple, robust, and sustainable character for public domain spaces.
This should be refl ected in uncomplicated, broad, and generous design structure and patterns formed by the confi guration of spaces, layout, materials, and colours of paving, and the layout and structure of tree and understorey planting.
Design solutions should respond to the strong visual and access linkages to the riverfront, providing a sequence of spaces and views to the river and open space of Tasker park beyond.
The development of the public domain should redress the lack of an existing “green” identity through the post industrial precinct. This may be established through the development of simple, robust, and bold street tree and open space planting approach that affords signifi cant and recognisable visual and recreational amenity.
Key Words for planning, design, and management
linkages riverfront riparianlinear & straight edged fl oodprone overlook
2 a vision for public domain
Character and identity are shaped by the cultural and physical characteristics of the site, the planning, design, and materials fabric developed, and the community usage and spirit that evolve.
CANTERBURY TOWN CENTRE PUBLIC DOMAIN STRATEGY PRELIMINARY DECEMBER 2007 9
2.2.1 Activation
A fundamental requirement for public domain development and management is the provision and facilitation of “active” public space. The level of activity primarily relates to how the space is perceived by a potential user. To encourage public use and become “active”, public areas must be clearly identifi ed as part of the public domain.
This is achieved partly through an appropriate level of continuity in design and materials theme, but also through the proportions / scale of the space in relation to adjoining uses. Public areas and access enclosed between other strongly private uses (eg residential) are usually of less value for public use and activity.
In addition to the scale and proportions of public domain, the treatment of the edges to adjoining uses is also important in achieving an “inviting” public space. Many existing public foreshore accessways to residential development are not successful due to a highly “privatised” character eg: continuing the design and materials identity of adjoining residential spaces and development.
The facilitation of safe and secure open spaces is also important in encouraging active usage. Sensible design, maintenance of adequate visibility and sight lines, appropriate lighting strategies, and realisation of an adequate level of use all contribute to a safe and secure public domain environment.
Finally the management of the public domain in realising public activity is important. The knowledge that the space may / will provide for high levels of usage and potentially generate noise and other impacts must be considered in the design of the space and of adjoining private open space and built form.
Strategy:
Public domain, adjoining uses and edges to adjoining uses to be designed and managed to recognise, facilitate, and encourage active use of the public space. Adjoining uses and edges to be designed in coordination with and consideration of, the design and intended / potential usage of public spaces.
Key Words for planning, design, and management
active interactive safeenlivened and fun public attraction generous space inclusive people friendly
a vision for public domain 2
Activation of public domain through facilitating and legitimating public use is a key strategy for Canterbury
CANTERBURY TOWN CENTRE PUBLIC DOMAIN STRATEGY10 PRELIMINARY DECEMBER 2007
2 a vision for public domain2.2.3 Places
In support of the creation of character and identity is the fundamental need to generate attractive “places”.
Places will become the recognisable and identifi able face of the town centre. The physical characteristics of the centre generate a number of obvious “place” opportunties including:
- the waterfront
- terraces overlooking the waterfront
- linking streets and lanes connecting the waterfront to the development
- the “main street” (Canterbury Road)
- the station transport interchange
Strategy:
Each of the places will have a functional role in which access will be a common factor. Certain areas will adjoin retail commercial frontages and may also cater for trading out by cafes and restaurants. Other areas should be more passive, with less structured usage and allowing for more low key informal use (eg seating, viewing).
It is appropriate that design and materials responses reinforce the identity and function of the spaces but also that common threads of continuity in design and materialscan link the spaces as part of an integrated whole.
Key Words for planning, design, and management
Variety Amenity LinkedSafe
A range of places will play a role in the public domain - each should promote a recognisable design and materials identity whilst maintaining an overall thread of continuity to recognise the centre as a whole
CANTERBURY TOWN CENTRE PUBLIC DOMAIN STRATEGY PRELIMINARY DECEMBER 2007 11
a vision for public domain 22.2.4 Sustainability
The selection and deployment of materials, management of waste and stormwater in the public domain, biodiversity benefi ts of plant selections, and control and management of human uses and activities are all factors that should be recognised in the planning and design processes.
Strategy:
A visible sustainable design practice is a priority of the public domain program. Design and deployment of materials should address the minimisation of the use of construction materials and products that deplete non-renewable natural resources, have high embodied energy values (in production), or create unreasonable or unnecessary pollution or other harm to the environment in their supply and / or production,
Where possible recycled materials should be used in public domain works including concrete, base course material for pavements, and landscape soils, planting mixes, and mulches.
Where possible use porous pavement surfaces to soft landscape fi nishes through open space to maximise infi ltration, assist ground water recharge.
Water sensitive design strategies such as infi ltration, and biofi ltration should be pursued to practical locations such as the riverfront walk.
The selection of plant material through the public domain must respond to functional and aesthetic criteria whilst maximising use of site indigenous plant material to improve habitat integrity. Such plant material should preferably be propagated from locally sourced cuttings or seed stock.
In addition planting schemes to the waterfront (the river walk) should aim to redress the loss of overhanging foreshore vegetation which is critical to healthy aquatic habitat.
The sustainable design treatments will aim to promote awareness of natural systems and values in the area and as such must be visible and understandable to the community. As such public domain should integrate coordinated interpretative measures including signage and public art that evaluate the public about the environmental strategies in place.
Key Words for planning, design, and management
Visible Systems Practical Maintainable
Sustainability should be recognised as a fi ndamental principle to be applied in a “whole of life” approach to public domain.
CANTERBURY TOWN CENTRE PUBLIC DOMAIN STRATEGY PRELIMINARY DECEMBER 2007 13
3.1 Generally
Design Principles are provided for each of the public domain components in the Canterbury Centre.
The principles are provided as a basis and reference for the development of public domain design and materials solutions. Principles are set out under generic headings relevant to the public domain component.
The principles for public domain components encompass several general goals:
• planning and design to facilitate and encourage community usage of public domain areas in particular to foreshore locations.
• a simple range of public domain design and materials approaches to enhance continuity and cost effectiveness / practicality for implementation and maintenance.
• sustainable design and materials strategies to be applied to all public domain areas.
• maximise compliance of public domain design and materials treatments with Disabilities Discrimination Act (DDA) requirements for universal access.
The principles are formatted as listed:

Biodiversity
• Enhance terrestrial and aquatic habitats to provide for a diversity of native fl ora and fauna
• promote a diversity of vegetative structure: native grasses and ground covers, shrubs, understorey and canopy species
• provision of natural ecological function/ processes where possible including infi ltration, habitat friendly seawall edge (eg niches in structure).
Issues to be addressed• landscape treatment of 2 metre level change between foreshore and main terrace
level for fl ood requirements
• recognition of existing urban or “man made” character of seawall edge to reclaimed land
• implications of potentially staged implementation on function of promenade,
• implications of potentially staged implementation on continuity of design, materials, and construction quality
• provide signifi cant riparian vegetation.

design & materials treatments 44.1 Design and Finishes Approaches
The preceding principles establish a framework for public domain planning and implementation through the Canterbury Town Centre. The defi nition of design and materials fi nishes to refl ect and support those principles is outlined following.
Overall the focus of the design and materials approaches is on simplicity and clarity, with the objective that the public domain can be easily understood and provides a cohesive system of pedestrian access, linking the foreshore promenade, street, network, plazas and parks.
The descriptions provided in Section 4.1 identify the various design and materials approaches that have been proposed to implement the design principles. Representative images of the various design or fi nishes ‘types’ are provided to give readers a vision of the character and quality of the public domain environment envisaged for Cahterbury.
Descriptions are presented in the key “elements” relating to public domain works:

4 design & materials treatmentsFootpath / pedestrian area pavement
Pavement must provide a hard wearing, cost effective and practically maintainable surface that establishes the identity of the centre and reinforces the continuity of public domain access.
In general terms a hierarchy of pavement surfaces has been proposed that refl ects the pedestrian signifi cance of the various components of the public domain.
The hierarchy is outlined following, and identifi es the components of the public domain included in that category:
Foreshore walk -the foreshore shared accessway
Major public domain -Canterbury Road to Jeffrey Street (with widened footpath)
-Canterbury Road east of Jeffrey Street (no widening)
-Market Lane -Charles Street east of Market lane -River Terraces at ends of pedestrian link streets
Secondary public domain -Charles Street west of Market lane -pedestrian link streets -Broughton Street
Foreshore walkIntent: to provide a simple utilitarian treatment that can cost effectively be extended for the full length of the walk providing a distinction in quality from general shared paths but maintaining a materials reference to those links
Where terrace spaces and steps adjoin the foreshore walk its is proposed that the shotblast concrete unit pavement of the plaza be extended into the promenade paving grids to signal and identify these nodal locations
Materials:• Exposed aggregate in situ concrete: 125 mm reinforced concrete slab with
selected aggregate mix - light abrasive blasting to provide exposure of fi ne aggregates. Jointing on regular pattern
• Honed concrete unit pavement: 800x400 shotblast concrete unit pavement on reinforced concrete base to areas adjoining terraces and steps to foreshore walk.
• Tactile indicators: tactile hazard and directional stainless steel indicators shall be used to meet the requirements of AS 1428.4 (2002), at driveways, fl ush crossings, pram ramps, and other hazards.
Major public domainIntent: to provide a quality pedestrian surface treatment that refl ects the pedestrian access and on street trading role of major public domain areas. A 800x400 paving unit is proposed to provide a visually simple pedestrian only surface, suitable for outdoors seating amenity related to cafes etc.
At driveways and crossing points pedestrian priority should be reinforced through use of interlocking pavers in matching colour to footpath.
Materials:• Shotblast concrete unit pavement: 800x400 shotblast concrete unit pavement
on reinforced concrete base:
base paving: mid - dark grey header / banding: light grey
• Interlocking pavement to driveways / crossings: 200x100mm honed reconstituted stone concrete unit pavement in herringbone pattern on reinforced concrete base. Concrete subbase design to have regard for requirements for vehicular access.
• Pram ramps: Shall be exposed aggregate concrete to match foreshore walk.
• Tactile indicators: as for Foreshore Walk

Intent: to provide a visually attractive and cost effective pavement treatment to all other street footpaths, that provides continuity in the public domain, a quality asphalt surface to provide identity and sense of quality.
At driveways and crossing points vehicular priority should be reinforced. Driveways to be standard broom fi nished concrete, whilst warranted crossings should be line marked on the asphalt roadway.
Materials:
• Asphalt: AC5 wearing course on AC20 bedding course reinforced concrete slab
• Pram ramps: Shall be exposed aggregate concrete to match foreshore walk.
• Tactile indicators: as for Foreshore Walk
Other MaterialsOther materials may be required and / or relevant for use in specifi c areas as features or as part of design strategies. These may include:
• Stone pavement: Stone pavement on a concrete base may be used as an accent or feature to
public domain spaces subject to detailed design development.
• Stabilised gravel: to provide a wearing surface under shaded seating areas, or to reduce extent
of hard paved surface to pedestrian spaces
Stabilised granite gravel (gold colour) on cement stabilised FCR is acceptable. This surface should not be used as a paving material within continuous accessible paths of travel.

Vehicular pavement
Should fundamentally be a utilitarian surface providing a safe and hard wearing medium for the movement of vehicles. In some cases vehicular access is required to pedestrianised zones and these pavements require a structurally suitable surface that denotes shared priority.
Surface fi nishes and their application is outlined following:
Asphalt roadway
Primary surfacing for all streets. Undertake services renewal / amplifi cation works prior to major road works and provide concrete base course to pavement.
Material: AC10 finish on basecourse as determined by engineering, traffic loadings.
Paved crossings - Interlocking pavement
Paved pedestrian crossings occur at the junctions of major east west streets with cross streets to reinforce pedestrian access connections
Material: Eco Pave exposed aggregate concrete unit pavement to match adjoining footpaths in smaller rectangular unit size on permeable base.
Shared zones - Interlocking pavement
Shared vehicular access zones may occur in large plaza spaces. Vehicular loadings preclude the use of large format paving units. Preferred treatment is interlocking “Eco paving”
Material: 80mm thick honed interlocking paving units on permeable base course. Subsurface drainage to link to stormwater system.
Parking Bays to minor roads - Interlocking pavement
To minor roads it is feasible to employ interlocking pavement - on grades up to 2.5% it is practical to use interlocking “Eco paving” as a means of water harvesting
Material: 80mm thick honed interlocking paving units on permeable base course. Subsurface drainage to link to stormwater system.

Kerbs and Gutters
Defi ne the pedestrian / vehicular junction of roads and footpaths and can signifi cantly affect the quality and legibility of the public domain environment.
A wider kerb is preferred when providing higher quality footpath treatment in particular with larger format paving. This is to maintain both elements in a similar visual scale.
An extruded kerb and gutter treatment of 300mm wide kerb / 500mm gutter (as is recommended to all roads.
Flush kerbs / edges

Generally furniture should be located as part of an coordinated design scheme for the public domain component in question. General principles for furniture deployment and layout are listed following:
Seats: • Foreshore walk: fi xed seating limited to designated locations to the foreshore
pedestrian walk - incidental seating provided through low walling to vegetation nodes
• Streets: locate at functional positions along pedestrian link streets adjoining tree pits perpendicular to kerb
• Plazas: locate off main circulation routes providing both shaded and sunny positions for seasonal change - provide wearing surface under
• Parks: locate off main circulation routes providing both shaded and sunny positions for seasonal change - provide wearing surface under

provide dual direction seating
• Streets: no installation to streets
• Plaza / squares: locate off main circulation routes providing both shaded and sunny positions for seasonal change - provide wearing surface under
• Parks: locate off main circulation routes providing both shaded and sunny positions for seasonal change - provide wearing surface under
Bollards: • locate as required adjoining link street shareways and at raised pedestrian
thresholds and other fl ush junctions of pedestrian areas with vehicle traffi c• set back 500mm (to face) from front of kerb
Bike Racks: • Foreshore walk: at stairway links to upper terraces• Streets: no installation to streets - generally - integrate adjoining rail station• Plaza / squares: locate off main circulation routes - preferably adjoining building

LightingTwo forms of street lighting are required to street corridors:• Vehicular Street Lighting Mast top / pole mounted street lighting to meet relevant RTA and Austroads
standards.• Pedestrian Lighting Pole top and under awning lighting to meet Australian standards.
Vehicular street lighting is often considered merely to meet functional requirements, without regard for the aesthetic potential of the light pole as a Street Furniture Element. The ‘Smart Pole’ as extensively implemented to City of Sydney’s is an exception to this norm.
Other lighting situations to be considered are:
1. Lighting of pedestrian access paths through parks for night time usage
2. Feature lighting of elements as visual displays (eg. sculpture/artwork elements, uplighting trees)
Pedestrian lighting of path accessways through parks should be evaluated for each potential site based on linkage value, and safety/security consideration. The use of pole top fi ttings to match those to pedestrian streets is the recommended approach to provide visual continuity.
Other forms of lighting that may be considered for individual plazas or parks include feature fl ood lighting or uplighting of park elements (statuary, signifi cant trees - subject to consideration of habitat impacts), and bud lighting of major avenues for special events or festivals.
Lighting types to be applied to Canterbury are as listed:
Street lighting
• Canterbury Road Smart Pole - 9m pole with pedestrian light fi itting
• Other Streets Energy Australia tapered pole - 9m pole
Pedestrian lighting
• Canterbury Road Under awning lighting to supplement Smart Poles
• Charles Street Pedestrian Light Pole (4.5m pole) (nom 12-24m)
- Foreshore link streets Pedestrian Light Pole (4.5m pole) (nom 12-24m)
- Foreshore Walk Pedestrian Light Pole (4.5m pole) (nom 14m)

design & materials treatments 4PlantingTree planting enhances the functional and visual amenity of the public domain and can ameliorate microclimate conditions though the provision of summer shade and winter sun. Lower level planting can enhance the layout and function of open spaces and assist in screening poor views.
In general lower level planting is proposed to be limited to selective use in plazas and parks, and to the central median of the east - west streets due to the constraint of ongoing intensive maintenance required by such plantings.
TreesTree planting will address multiple objectives in the public domain including both functional and design / visual roles. Tree planting function, proposed layout and species is listed following:
Foreshore promenade: - Eucalytpus robusta (Swamp Mahogany - Sydney native) as typical Sydney
foreshore planting to water edge situations - high and dappled canopy allows for effective views under canopy
- Water edge / overhanging planting refl ecting riparian species (eg. Eucalyptus robusta - Swamp Mahogany, Banksia integrifolia - Coastal Banksia, Melaleuca styphelioides - Prickly Leafed Paperbark)
Canterbury Road- Angophora costata (Smooth Barked Apple - Sydney native) as street tree
planting
Charles Street / Broughton Street- Lophostemon confertus Brushbox - native) as street tree planting
Plazas / Squares- Nodal plantings as required for site specifi c design of plaza spaces
- Native tree plantings in groups to edges of plazas/ squares as buffer zones and and to provide shade
Parks
- Various native tree plantings in groups to edges of parks and to provide shade.
Tree supplyTrees for use in all public domain areas with the exception of parks will be of the following minimum sizes:
- Canterbury Road 400L - 4-5 metres height
- Other streets 200L - 3.5-4 metres height
- Foreshore Walk 200L - 3.5-4 metres height
Tree pit preparationTree pits shall be provided with at least the following minimum preparation to ensure their establishment and long term development:
- 150mm cultivated subbase
- subsoil drainage connected to stormwater system
- imported planting mix
- mulch to suit planting situation
Tree surroundsA permeable but traffi cable treatment is proposed for installation to the top of tree pits. Several options have been trailed by Sydney City Council with a neutral “grey” coloured pea gravel with organic stabiliser preferred.

CANTERBURY TOWN CENTRE PUBLIC DOMAIN STRATEGY44 PRELIMINARY DECEMBER 2007
Garden bed PlantingsShould be limited to selected locations in Plazas Squares and parks to provide important design function, in order to limit recurrent maintenance requirements.
Planting beds in general should not exceed 2.5 metres in width (for maintainability) and should meet the following preparation requirements:
- 150mm cultivated subbase
- subsoil drainage connected to stormwater system
- 300mm imported planting mix
- 75mm native leaf chip mulch
Suitable species should predominantly be local and Sydney native species, with the aim of enhancing biodiversity values through the precinct.
Trellis PlantingsPlanting trellis frames are proposed to be employed at regular intervals along the foreshore walk mounted to the face of the basement carpark walling adjoining the walk.
These will be a purpose designed stainless steel frame 3x3m with vertical stainless steel wire rope at 150mm intervals. Frames will be placed at intervals offset with native grassing panels to foreshore.
Native GrassingNative grassing is being used extensively through the river corridor and will be used to the foreshore walk and some open space situations.
Native grassing may be used as a low maintenance groundcover maintaining visual access under tree canopies to group tree planting stands, and as a groundcover only to defi ne pedestrian traffi cable areas where used in conjunction with low profi ling of the ground surface (to parks only)
native grassing beds should meet the following preparation requirements:
- 150mm cultivated subbase
- 50mm imported compost mix cultivated into existing site soil
- 75mm native leaf chip mulch
Turfi ngTurfi ng will primarily occur in parks and should meet the following preparation requirements:
- 150mm cultivated subbase
- subsoil drainage connected to stormwater system
- 300mm imported planting mix
- 75mm native leaf chip mulch
Turf species to be Wintergreen Couch.

It is preferred that the use of fences and barriers is minimised through the public domain to reinforce connectivity and maximise visual continuity on this fl at site. However where such barriers are required it is essential that a coordinated approach is applied.
Requirements for fences and barriers are listed following
Palisade fenceApplication:a quality steel palisade fence s proposed to be used wherever a medium term to permanent fenced edge is required.
Treatment:galvanised steel posts with top and bottom rails and circular pickets
River walk balustradeApplication:
A galvanised steel balsutrade is proposed at the river channel edge.
This should be a site specifi c design that is identifi able with the site, and provides an architectural / public art theme where possible. Treatment:
Design development of this detail is required for general application along the river edge
Water access points / DecksApplication:
Provision for water access for recreational purposes is not recommended as part of this plan.
There are several areas where decking is proposed to extend pedestrian cycle movement space. Primarily these occur under the Canterbury Road brideg and on the Market Lane axis.
Treatment:These are proposed to be implemented as steel frame structure with a decking material to be confi rmed through design development. Several options are available as alternatives to typical timber decking which has a limited lifespan in this context.
These include:
- tight steel grid mesh decking
- pre-cast concrete sleeper (eg “permatrak)
- recycled plastic decking

Signage
Signage ApproachSignage is an important element of the public domain assisting the comfortable use and enjoyment of public areas. However if poorly resolved and located, it can also detract from the visual qualities of public areas, and frustrate users.
Signage should be coordinated in approach, design and materials across the Hurstville City Centre to reinforce the overall identity and aid legibility for visitors and locals alike.
General Principles• Develop an overall signage character and identity to be consistent
through the Canterbury Town Centre with contextual links to signage in canterbury LGA generally
• Develop a hierarchy of signage a) Town entry / identity (Vehicular) b) Town orientation (Vehicular) c) Way fi nding (Pedestrian) d) Place (Vehicular + Pedestrian) e) Community Information boards (Pedestrian) f) Interpretative signage• Materials to refl ect natural themes and cultivate relevant man made
materials.• The placement of signs is to refl ect the structure developed in
coordinated public domain design.• The scale, form and location of signs should respond to the scale and
role of the space they occupy (park environments, roadways, pedestrian paths etc) and the manner in which they are viewed (pedestrian or vehicular).
• Provide signs where necessary but avoid the proliferation of signs. Use of signage to reinforce the design aim of enabling spaces to reveal the patterns of past and future use.
• Signs are to convey information clearly and to conform to the relevant Australian Standard.
• To enable original signage to be understood and interpreted by visitors it is important that new signage provide a simple contemporary character.
• Signage structures, materials and fi nishes of elements shall meet the relevant criteria and guidelines that apply to furniture and pavement elements. Elements should be robust, vandal resistant, weather proof, require minimal ongoing maintenance and are to be cost effi cient.
• General maintenance of earlier signage associated with earlier usages should be continued and provision made for repainting or replacing when the signage lifespan is reached.
• Siting of signage shall be undertaken to provide the optimum visual relationship to support public use and interpretation
Maintenance :• It is preferred that repairs or refurbishment of the signs is not overly
specialised.• Ensure that interchangable parts can be part of a modular system that
will remain fl exible for all site conditions.• Ensure elements can easily be attached and removed economically for
upgrades and maintenance.• Ensure that mounting components are absolutely tamperproof and fi xed
in ways to prevent “souvenir theft”.• Graffi ti, if it occurs, should be easily removed without damage to a sign,
and without the need for hazardous chemicals.

design & materials treatments 4
a) Town entry / identity (Vehicular)Sign Function :• Entry signs identify the boundary or entry point of the City Centre to the visitor.• Reinforce Canterbury character.Location/siting Guidelines :• Near a signifi cant or highly visible entrance.• The entry signs should be along a path of travel, be that vehicular,
pedestrian or both.• Motorists usually read signs on the move and need information in
advance of decision points.• Maps should integrate and relate to the hierarchical principles
established for vehicular routes on each site.
c) Way fi nding (Vehicular)Sign Function :• Large wayfi nding signage is primarily used as a navigational tool for
vehicles at precinct entries or major decision points.Location/siting Guidelines :• Should be visible along a chosen route.• Sign location is 10 - 15º off perpendicular to the road of travel.• Arrows are used to defi ne the directions of travel at that decision point
and should be in order of destination occurrence.
c) Way fi nding (Pedestrian)Directional Signage Hierarchy :• Pedestrians generally stop to read even simple signs and need them
at decision points; pedestrians want to be aware of their destination (or the route to the next sign) before they make a decision.
• Maps should integrate and relate to the hierarchical principles established for pedestrian routes around the City Centre and allow for
the correct fi ltration of information within walking distances deemed achievable for the average visitor.
Sign Function :• Orientation signs provide the information required for a visitor to
learn and understand the track route.• The display plate is for a map viewed in conjunction with interpretive
information.• Precinct map can be colour coded to assist with identifi cation of a
specifi c buiding within a group of buildings.• “You are here” symbol to be used.• Wheelchair accessibility should be notifi ed.• Notice panel provides for interchangable A3 format posters produced in-house by Council.• Medium wayfi nding signage is primarily used as a navigational tool for
both vehicles and pedestrians and will be placed along a path of travel or at secondary decision points.
Location/siting Guidelines :• Should be visible along a chosen path.• Location should be perpendicular to the path of travel.• Sign location also depends on the users approach direction and their
line of sight.• Arrows are used to defi ne the directions of travel at that decision point and
are to be in order of destination occurrence.
d) Place (Vehicular + Pedestrian)Sign Function :• Freestanding sign to identify a place and /or a Building.• Wall mounted sign to identify a place and /or a Building.• Reinforce Canterbury identity / ownership.Location/siting Guidelines :• Should be visible from a distance by cars and pedestrians.• Sign location also depends on the users line of sight.• Sign location may depend on the architecture of a building or structure
to which it is attached.
CANTERBURY TOWN CENTRE PUBLIC DOMAIN STRATEGY48 PRELIMINARY DECEMBER 2007
Signage (continued)
g) Interpretive (Pedestrian)Sign Function :• Interpretive signs are typically low profi le signs that explain what you can
see, smell, hear, etc. from that sign, and are therefore quite site specifi c.• Artworks can be used to tell stories that enrich experiences, convey
impressions and act as identifi able wayfi nding features. Each display panel is quite site specifi c.
• The stories each sign tells should be strategically tied to a broader interpretive masterplan that covers a spread of themes throughout a precinct and places messages where they are most effective, without clutter or duplicating themes.
• Interpretive signage that provides a basis for evolving interpretation ( eg. photos to trace physical changes) can supplement environmental and historical information.
Location/siting Guidelines :• the interpretive signs would typically be located where the interpretive
message can be best delivered.• Interpretive signage should occur as a source of information visually
integrated with other Public Domain elements that supplements the user experience and understanding of the site.

Services / Infrastructure
Services provisions to streetscape have a signifi cant impact on the quality of street environment through both the immediate appearance of services or service lids, or through the damage to road and footpath pavements caused when random authorities works are carried out.
Key principles for the ‘low impact’ integration of necessary services and infrastructure elements within public domain areas are:
1. Under-grounding of overhead services carried out where feasible to major street corridors to reduce visual intrusion and enhance aerial amenity for street trees
2. New developments to integrate under-grounding of services and infrastructure as part of planning
3. Where possible identify design schemes for at least full street blocks, and liaise with service authorities to determine renewal or amplifi cation requirements and incorporate these works into programming prior to pavement renewal
4. Provide common texture and shape to electricity service covers (i.e. during upgrade projects)
5. Provide lids to Telstra pits with paving infi ll to match adjoining pavement
The provision of stormwater drainage to streetscape improvement zones can also be problematic in particular at footpath widening where no underground stormwater services are available.
Key principals for consideration of stormwater drainage in streetscape design are:
6. Provide a common theme to all stormwater inlet sump and channel lids / grates to paved areas
7. Connect rooftop downpipe to underground stormwater in public domain upgrade works
8. Incorporate natural disposal and surface drainage techniques where possible to urban spaces and open spaces
9. Incorporate water sensitive urban design and technology to treatment of road stormwater runoff
10. Incorporate porous pavements and on site detention to carpark areas to reduce urban stormwater runoff
Stormwater Management
It is proposed that to the major east west streets that planted areas allow water to re-enter the groundwater system.
The potential for the foreshore planting strip adjoining the Foreshore Walk and the walled edge to adjoining development is explored for biofi ltartion potential as part of the overall stromwater system.
Grades preclude effective buiofi ltration to most streets in the centre
All roof runoff is to be collected by the stormwater system and directed to a water harvesting and recycling system.
Filter meshes should be fi tted to stormwater inlet pits to prevent leaf transport, and subject to regular maintenance during critical months of the year. Leaves are a major source of Eutrophication (de oxygenisation) of aquatic habitat.
