1.0 executive summary

The Mundaring Weir Interpretation Precinct Blueprint identifies locations for interpretation and upgrades to public areas around Mundaring Weir and surrounds. Water Corporation has undertaken the project with input from the Project Steering Group and other stakeholders with the aim of developing visitor experiences in the area and presenting the precinct as a cohesive whole. Interpretation work will coincide with the construction of the Water Treatment Plant and associated facilities.

The Mundaring Weir precinct consists of a small number of public and private facilities and Water Corporation assets situated within approximately 1 kilometre of the weir. The precinct, whilst popular, has poor accessibility in some areas and some important public facilities require upgrades. A coordinated approach to interpretation will also extend the viability of the weir as a tourist destination.

The design includes the upper and lower precinct hubs that form the major locations for visitor access. Upgrades including car parking, landscaped spaces and amenities will be focused in these locations. Interpretive elements will be incorporated with the hub design and throughout the greater precinct. These will be used to orient visitors, convey the historic significance, contemporary context and future vision of the weir and its surrounding attractions.

Interpretive elements and upgrades will support the rich character of the precinct through an integrated and interlinked approach. Key entry points and visitor destinations within the precinct are defined and links to the broader region through the trail network and Mundaring Sculpture Park are also considered.

This report presents the blueprint design for the interpretation precinct and supporting background information. It includes; a brief description of the project context; site analysis describing important biophysical and socio‐cultural aspects of the area; opportunities and constraints considered in the blueprint plan; the design approach for interpretation and the blueprint design. The blueprint design identifies locations where interpretation and upgrades will occur, landscape concept plans and a description of the design intent.

Interpretation and upgrades to the precinct are set to coincide with the construction of Water Corporation assets associated with the new Water Treatment Plant. Concepts presented in the Interpretation Precinct Design will be completed by 2014 to coincide with the Water Treatment Plant Works.

2.0 introduction 2.1 project context

The Mundaring Weir Precinct is a destination of regional and national significance situated around the weir – a key element of Western Australia’s water infrastructure. The weir plays a primary role in the network supplying safe drinking water to the state. Surrounding areas are an important tourist destination, valued for the unique natural landscape and historic significance.

Recognising the importance of tourism to the area, the Water Corporation has made a commitment to provide interpretation elements and associated upgrades in the precinct. Originally this was to take the form of an ‘interpretive facility’ however this has evolved into that of an ‘interpretation precinct’ in line with feedback provided by the community, stakeholders and visitors the area.

The Water Corporation is collaborating with other agencies involved in the area – as well as the local Shire of Mundaring – to deliver on this commitment, and identify the scope of work that should be undertaken. Completion of the interpretation and upgrade works by the end of 2014 in line with the completion of the Water Treatment Plant and associated works forms part of the Water Corporations commitment.

2.2 study area

For the purposes of this report the precinct is defined as the small number of public and private facilities and Water Corporation assets situated within approximately 1 kilometre of the weir. Consideration of the biophysical and socio‐cultural aspects of the precinct, the Helena Valley and the relationship to the towns of Mundaring and Kalamunda are key elements of the study. Perth, the Eastern Goldfields and Golden Pipeline also provide important regional context to the project.

3.0 consultation Achieving innovative and sustainable outcomes requires a strong collaboration with the design team and key stakeholders. Throughout this phase of the project, Ecoscape has worked collaboratively with various consultants and stakeholders to ensure that a consistent approach to the blueprint design and interpretation is achieved.

3.1 stakeholders

The Water Corporation is the largest stakeholder in the project due to the management of water infrastructure and associated assets. The Water Corporation share decision making authority on the project with the Project Steering Group that includes:

• Department of Environment and Conservation • Shire of Mundaring • National Trust of Australia (WA).

In addition to the Steering Group, the interests of other groups were considered to ensure a comprehensive blueprint was developed for the Precinct. These Stakeholders include:

• Department of Water (DOW) • Mundaring Weir Water Supply Improvement Project (MWWSIP) Community Reference Group • Eastern Hills Business Association • Eastern Hills Historical Society • Mundaring and Hills Historical Society • Mundaring Arts Centre • Mundaring Weir Hotel • Perth Hills Centre • Shire of Kalamunda • Shire of Mundaring • Western Power.

3.2 consultation process

Ecoscape was engaged by the Water Corporation in November 2010 to prepare a Blueprint report on the development of the interpretation precinct facilities at Mundaring Weir. The consultation process included regular project meetings with Water Corporation staff, as well as milestone meetings with the Steering Group and the MWWSIP Community Reference Group. Additional input has been provided by the National Trust with regards to attractions under their management.

Mundaring Weir Water Supply Improvement Project (MWWSIP) Community Reference Group

The MWWSIP Community Reference Group was established to facilitate discussion of the proposed works at Mundaring Weir. Representatives from the local government authorities and community groups were consulted to ensure that the Shires and local community remain informed about proposed development and have the opportunity to raise issues and concerns.

A MWWSIP Community Reference Group meeting was held on 8th March 2011 in which Ecoscape was invited to present draft concepts for discussion and feedback. Community Reference Group representatives present at this meeting included John Beaton, Diana Frylinck, Myles Harmer, Fiona Jordan and Jens Jorgensen. Members were invited to provide additional feedback to the Water Corporation following the meeting.

Steering Group

Ecoscape was invited to present an overview of the design process and outcomes to a Steering Group meeting held on 22nd March 2011. The Steering Group provided feedback and direction based on this meeting that has been incorporated into the blueprint plan.

National Trust

In addition to these meetings, Ecoscape and the Water Corporation met with National Trust of Western Australia Representative Anne Brake on 31st March 2011 to get a greater understanding of the assets managed by the organisation and the opportunities for interpretation that they present.

Interpretation Consultancy

Water Corporation engaged interpretation consultant Savagely Creative to prepare an interpretation plan for the development of the water treatment plant in the Portagabra site. The Mundaring Weir Water Treatment Plant Interpretation Plan uses a thematic approach that defines a series of sub‐ themes for the site. The plan covers aspects such as Portagbra, water, forestry and the development of Western Australia and forms the basis for interpretation shown in the blueprint plan

4.0 site analysis 4.1 context and climate

Mundaring Weir is located approximately 30km east of the Perth CBD, within the eastern boundary of the Perth metropolitan area. The precinct straddles the boundary between the Shire of Mundaring and the Shire of Kalamunda. The weir defines the boundary between the upper and middle Catchments with C.Y. O’Connor Lake situated in the upper catchment.

The Precinct is accessed via with the most direct route from Perth coming from . Mundaring Weir Road is a popular scenic route particularly for weekend visitors coming to see the weir and surrounding attractions. The township of Mundaring is also closely linked to the precinct.

Key locations include:

• The weir wall that is the primary focus of most visits. Access is usually from the southern car park due to proximity and ease of access • Number 1 Pump Station, Managed by the National Trust of Australia (WA) that exhibits the heritage of the weir and Golden Pipeline catering to tourists and school groups • The Perth Hills National Park Centre, managed by the Department of Conservation (DEC), that provides interpretive facilities for the surrounding and is a popular trail head in the area • South Ledge (Golden View) lookout where expansive views of the weir, lake and valley can be enjoyed. • North Ledge lookout from where expansive views of the weir and valley can be enjoyed by trail users. • Fred Jacoby Park, managed by DEC that includes picnic facilities and has recently received upgrades to access, interpretation and landscaping. • Picnic areas occur along Mundaring Weir Road that may provide future opportunities for interpretive work.

The study area is characterised by a mild Mediterranean climate. Meteorological conditions vary seasonally with rainfall, temperature and wind patterns following a well‐defined annual cycle of hot dry summers and mild wet winters. The majority of rainfall occurs in the winter months (June – August). Refer to Figure 2: Context & Climate.

4.2 topography and drainage

The precinct is located on the Darling Plateau in the Helena Valley approximately 300 metres above sea level. Terrain within the study area is characterised by undulating topography incised by numerous steep V‐shaped valleys. Drainage occurs along these valleys towards the Helena River, the main waterway that travels downstream to become a tributary of the Swan River. Water in the river is seasonal, occurring with winter rainfall whilst drying up to intermittent pools in summer.

Refer to Figure 3: Topography & Drainage for details of the drainage and topography within the study area.

The precinct is situated between the Mundaring Weir catchment and the Middle Helena Catchment. The Mundaring Weir Catchment area, flows into C.Y. O’Connor Lake to form the drinking water source. The Middle Helena Catchment area includes valleys and sub‐catchments located downstream. The lake receives water from the Middle Helena via the pumpback dam.

In the precinct area there are significant level changes and slopes from the valley floor to the weir wall and the rose garden picnic area. These have a significant impact on vehicle and pedestrian circulation and sight lines throughout the precinct.

4.3 vegetation, geomorphology and soils

Historically, vegetation within the study area has been extensively modified as part of the Mundaring Weir Forestry Settlement Scheme and other land use practices. The forestry settlement scheme included plantations as a timber resource that would also aid in restoring catchment health. These included Eucalypt sp. and Pinus sp. that were well suited to timber production.

Near the weir, trees were cleared extensively for the dam construction on the southern and northern sides of the weir wall and these areas still have minimal understorey and sparser tree growth. Historic plantings including exotic tree and plant species around the weir, particularly near the Rose Garden, are well established and provide significant amenity to the area.

Some areas are displaying signs of dieback [Phytophthora cinnamomi] in places. For this reason dieback tolerant plants must be selected for all future planting in these areas.

Geomorphologic associations incorporate geomorphology, soil type and vegetation. There are five major associations occurring within the study area. They relate closely to the landform, with different complexes occurring in the valleys, ridges and across the steep slopes of the scarp. The associations may provide strong narratives for interpretation of the natural assets of the precinct.

Below is an outline of the geomorphologic associations found within the study area.

4.4 land use, reserves and drinking water source management

MANAGING THE DRINKING WATER SOURCE

Mundaring Weir provides clean potable water to the Eastern Goldfields rural areas and part of the metropolitan area. The security of the source is of the highest priority and the Mundaring Weir Catchment and Middle Helena Catchment are proclaimed Public Drinking Water Source Areas under the Country Areas Water Supply Act of 1947. The Department of Water (DoW) is responsible for the protection of water sources used for public drinking water supply and at Mundaring Weir this responsibility is delegated to Water Corporation. Figure 5: Landuse & Reserves illustrates this zone and the other land uses, reserves and protection zones in the region.

Land uses in the catchment are carefully managed to ensure the security of the drinking water source. The precinct is located in a Priority 1 Water Source Protection Area, and in accordance with current government policy and by‐laws, includes a Reservoir Protection Zone (RPZ) to avoid the risk of microbiological contamination. The RPZ prohibits unauthorized access to the reservoir and restricts access to part of the catchment area located upstream of the dam and within 2km of the top of the water level. Public access in the RPZ is restricted to travel on public roads or picnicking within designated picnic sites. Development within these areas must comply with Department of Water drinking water source protection plans and by‐laws.

TOURISM

Tourism has played an important role in the history of the weir as its construction attracted day trips by rail resulting in the development of pleasure grounds such as the Rose Garden near the weir wall. The interest and appeal continues today with many visitors coming to see the weir wall and surrounding attractions. The greater area surrounding Mundaring Weir includes national parks, state forest, parklands and reserves. The Department of Environment and Conservation manages many of these including Beelu National Park, the State Forest and Fred Jacoby Park

HISTORIC LAND USES

The study area has seen a number of land uses since European settlement resulting in extensive modification that is evident in today’s landscape. Following initial use of the land for agricultural purposes the State Government in 1898 moved to construct the Mundaring Weir to supply the newly discovered Eastern Goldfields. Extensive clearing of forests by ringbarking accompanied the weir construction and resulted in environmental degradation. In the 1920’s forestry was implemented in the area to help ameliorate the environmental issues and foster the timber industry in the area. The Mundaring Weir Forestry Settlement was established at Portagabra and various tree crops were trialled. As a result the landscape today supports heavily wooded replanted areas that appear to have naturalised and integrated with surrounding forest areas. The precinct now has a small number of residences located near the Mundaring Weir Hotel and along Weir Village Road.

4.5 recreation facilities and trails

The network of trails surrounding the precinct is an important asset that attracts visitors and provides a range of benefits including increased tourism, economic returns, educational opportunities, ecological awareness and community participation. The study area features a number of iconic, local and regional trail networks. The tracks serve a multitude of users, in particular walkers and mountain bike riders. Many of the trails overlap to form the network and provide the main linkages.

Popular trail heads include:

• The community hall (Arts and Crafts Centre) opposite the Mundaring Weir Hotel that is the Trail head for the O’ Connor Trail and Kep Track. • No.1 Pump Station, The trail head for the Weir Walk and western terminus of the Golden Pipeline Heritage Trail. • The Perth Hills National Park Centre that has a popular car park and is the trail head for many trails in the Beelu National Park.

There are many trails that overlap through the study area. For the purposes of this report, 2 short trails and 4 long trails are identified as having particular relevance.

Important short‐trails that provide pedestrian connectivity through the precinct include:

• Weir Walk that takes visitors around the main weir area to see No1. Pump Station, the wall and Rose garden. • O’Connor trail that connects the Perth Hills National Park Centre to the Mundaring Weir hotel via the woodland and lake lookout.

Long‐trails are regional trails that have a terminus or pass through the precinct. They include:

• Bibbulmun Track form Kalamunda to Albany • Kep Track From Mundaring Weir to Northam • Golden Pipeline Heritage Trail from Mundaring to . • Munda Biddi mountain bike trail.

The trail from Mundaring Sculpture Park is also noted as an important connection that follows the rail and pipeline to the precinct. This is a route shared by a number of trails including the Kep Track. Refer to Figure 6: Recreation Facilities & Trails for key recreational locations and trail routes within the study area.

5.0 opportunities and constraints The Mundaring Weir precinct is rich in natural beauty and heritage that make it a popular recreational destination and a place that can enliven the story of Western Australia’s development. Interpretation installations and landscape upgrades are subject to a number of opportunities and constraints that exist within the precinct which should be considered.

5.1 water source security

The precinct is located in a Priority 1 Water Source Protection Area and areas closer to the lake and weir are also subject to the Reservoir Protection Zone (RPZ). Contamination risk development in the RPZ must be avoided i.e. new amenities and turf areas. Parking areas should be as remote as is practicable from waterways and unauthorized access to the reservoir is prohibited. Designs should also prevent the occurrence of soil erosion and new trails should not be considered within the RPZ.

A large portion of the precinct is in the Middle Helena catchment that has restrictions to development as noted in the Middle Helena Catchment Strategy 2010 by the Western Australian Planning commission.

5.2 operational facilities

The weir is an operational facility that has requirements for the day to day management of the scheme water supply. Access to operational areas and the reservoir is restricted to Water Corporation personnel only. By managing movement around the weir, public use will coexist with Water Corporation’s operations. The safety of visitors and personnel will not be compromised and will be a high priority at all times. Attractions, thresholds and development of preferred trail links can help manage this. Design and installation of interpretation and upgrades will need to be mindful of works associated with the Water treatment Plant and their timing to ensure that the positive experience of the weir is maintained.

5.3 mundaring weir water supply improvement project

The Mundaring Weir Water Supply Improvement Project includes the upcoming construction of new facilities that will ensure reliable compliance with current Australian Drinking Water Guidelines for the Goldfields and Agricultural Water Supply Scheme. The Project involves the construction of several new assets at or near Mundaring Weir between 2010 and 2014. The scope of the project includes:

• The water treatment plant (WTP) located on Mundaring Weir Road.

© Ecoscape (Australia) Pty Ltd 7678‐2566‐10R 17

• Pump station C at the base of the weir near Number 1 Pump Station that requires the movement of vehicle access for No.1 Pump Station to the south side of the river. • New works to the Weir Wall that will intermittently restrict access on the northern end of the weir. • Relocation of the Department of Environment and Conservation, Perth Hills District Office to the new Allen Road site.

Each of these are valuable opportunities for interpretation however their construction and that of landscape and interpretive works need to be carefully timed to ensure that visitor experience and stakeholder interests are not adversely impacted.

5.4 entry statements and gateways

Entry statements and gateways serve as useful tools in defining the arrival or departure of a destination or precinct. Currently there is no definitive entry statement or gateway defining the Mundaring Weir Precinct. An opportunity exists to implement precinct gateways in Mundaring and Kalamunda to alert visitors to the location of the precinct; as well as entry statements within the immediate vicinity of the Weir at key entrance points, to let visitors know when they are approaching the Mundaring Weir Precinct.

5.5 signage

The existing directional and regulatory signage relating to Mundaring Weir, both locally and regionally lacks clarity. Therefore, there is an opportunity for a review of the existing signage scheme. A committee comprising of Tourism Western Australia, Main Roads and Mundaring Weir stakeholders prepared the ‘Mundaring Weir Signage Strategy’ which addresses many of the signage issues of visual clutter and poor comprehension that currently exist in relation to the weir. In conjunction with this scheme, a cohesive approach may be undertaken to improving the signage within and around Mundaring Weir. In some instances signage should be rationalised to make navigation easier. Water Corporation’ Corporate Catchment Signage (S111) should also be referred to for source protection signage.

5.6 interpretive signage and artworks

Interpretive signage and artworks play an important role in informing visitors about the natural, historical and cultural context of a site. Making visitors informed engenders them with a sense of ownership and responsibility over the place.

A number of existing interpretive and educational signs are located around the precinct and in particular at the No.1 Pump Station, the C.Y. O’Connor Memorial and the main car park facilities. An opportunity exists to build upon the existing signage scheme to enhance the visitor experience and

© Ecoscape (Australia) Pty Ltd 7678‐2566‐10R 18

understanding. It is recommended that key themes and locations for interpretation be further developed in line with the report developed by Savagely Creative to provide continuity in the information presented and enable encourage further exploration. Signage previously installed by the National Trust of Australia (WA) is well designed and robust. It is recommended that future signage builds upon this design language to produce a coherent precinct wide approach and should take into consideration the Water Corporation’s current Corporate Catchment Signage Standard.

5.7 access and parking

Existing access to the northern part of the site is currently sufficient and well used during events at the Mundaring Weir Hotel. Opportunities are available to formalise parking at the termination of Weir Village Road, and within the one‐way access and parking facility at the crest of the hill, adjacent to the Rose Garden. This would aid in maximising visitor capacity and improve amenity.

The access road and associated car park to the base of the weir wall on the southern bank of the Helena River has the potential to be formalised. Consideration should be given to an alternative entry point off Mundaring Weir Road due to poor sight lines.

The car park at the southern end of the weir provides a popular access point to the wall’s walkway due to the ease of access. A walkway from the Car park to the wall could facilitate disabled access. Due to the proximity of heritage elements this should be a raised boardwalk structure and include consideration of its connection to the balustrades of the existing walkway.

The car park is on a tight corner of the road and would benefit from formalisation, adequate signage and traffic control measures on Mundaring Weir Road. A lower speed limit beginning well before the bend should be considered due to the amount of traffic entering and the incidence of visitors using the Bibbulmun Track crossing here.

There is an opportunity to adapt existing car parking facilities to use Water Sensitive Urban Design (WSUD) practices. Incorporation of swales to all parking facilities would allow the infiltration of stormwater run‐off. This is a valuable tool in demonstrating to the public practical applications of WSUD principles in this sensitive area.

5.8 amenity and maintenance

At present, public amenities at Mundaring Weir are scattered through the site. Connectivity between these amenities is at times disjointed and many of the facilities themselves are in need of an upgrade. Formalising and focusing infrastructure in key locations will provide destination points for visitors and provide efficiencies in funding.

The precinct contains landscape areas with large expanses of turf which are in poor condition. An opportunity exists to reduce the amount of turf in the study area, and retain it only where it is has a

© Ecoscape (Australia) Pty Ltd 7678‐2566‐10R 19

high recreation value. This will reduce the maintenance and water required for the upkeep of the turf. Synthetic turf, softfall surfacing in play areas and native groundcover planting could also be employed to reduce overall areas of turf and will demonstrate responsible alternatives to its use. Strategic tree plantings within car parks and at interpretation nodes will also contribute to the visual amenity of the precinct and provide additional shade to otherwise exposed areas.

5.9 further interpretation opportunities

There are additional opportunities for interpretation within the broader precinct identified on the Contextual Opportunities Plan‐ Figure 7. These have been identified in the preparation of the blueprint plan but do not form part of the current proposal. They include:

• Identification of the differing landscape characters and vegetation complexes experienced within the region (township, bushland, valley, semi‐rural, dieback, valley and valley floor) and increasing awareness of environmental responsibility. • Improved identification of North and South ledge • Improved awareness of Fred Jacoby Park and stronger links to the precinct via the trail network • Improved connection to the Mundaring Weir Hotel and incorporation into the interpretation strategy.

These interpretation opportunities may be included in future works aimed at consolidating the character and identity of the precinct and further strengthening the connection between the weir and town of Mundaring.

6.0 design approach The blueprint plan’s design approach aims to develop the visitor experience of the precinct as a cohesive unit comprising of many interrelated and unique elements that are highlighted by effective interpretation and supported by upgrades to amenities and associated landscapes.

Interpretation and upgrades will promote links within the precinct and ensure a rich visitor experience. The aim of interpretation is to increase the visitor’s awareness of the place in a way that is enjoyable and thought provoking. Positive visitor experiences will in turn strengthen the precinct’s popularity and viability as a recreational destination.

6.1 thematic interpretation

The interpretation strategy is thematic and uses a central theme to interlink individual installations throughout the precinct. Each installation will explore both a sub theme and narrative, based on its location, and also consider its relationship to the overall theme. From this structure visitors receive an overall message and awareness bound to their experience of the place. Thematic interpretation favours visitors’ experience over factual recall and aims to inspire individual thought to establish deeper meanings and connections.

To successfully transmit the theme and invite exploration of the place, interpretation should be entertaining, organised and relevant and can provide insight into heritage, current conditions and future directions

MUNDARING WEIR WATER TREATMENT PLANT INTERPRETATION PLAN

The Mundaring Weir Water Treatment Plant Interpretation Plan has been prepared by Interpretation consultants Savagely Creative for the Water Corporation. =This report has identified the following central theme:

“Western Australia was settled and developed as a result of innovative engineering, ingenuity and brave decision makers.”

Six sub‐themes and associated stories were also developed to support the theme including:

• Climate Change • Developing Western Australia • Experimentation • Forestry • Water Management and security • Developing Western Australia

© Ecoscape (Australia) Pty Ltd 7678‐2566‐10R 22

In collaboration with the Steering Group additional sub themes were added that include: • The Mundaring railway • Indigenous heritage

Sub themes and narratives are flexible and should be explored further by stakeholders who are involved in the design of installations. Whilst there is scope for these to be developed they should relate to the central theme to ensure relevance and coherence with the greater plan.

6.2 planning, landscape and amenity

The blueprint plan has been developed to organise the visitor experience, to ensure that attractions are connected, accessible and enjoyable and to support the precinct’s interpretive theme.

HUBS & NODES

The blueprint plan includes Hubs and Nodes as the main focus for visitor attractions and amenity.

A ‘hub’ is identified as a discrete group of public amenities that offers a range of facilities including shelters, barbeques, tables, seating, drinking fountains, playgrounds and parking. They are the major locations where visitors will come to receive orientation and information about the weir’s attractions and context. Hubs will include significant interpretation that present an overview of the narratives of the precinct and maps of the trail network.

Hubs constitute high amenity areas and their location has been informed by a number of factors including accessibility, development restrictions and upcoming works related to the new Water Treatment Plant. Figure 8: Hub Opportunities Plan illustrates the proposed locations and lists the associated pros and cons with each location that were discussed as part of the planning process. Following consultation with Water Corporation, two hubs were identified as preferred options for progression into the concept design phase. They included options ‘A’ and ‘C’ and were re‐named the Upper and Lower hubs respectively.

‘Nodes’ are identified as locations for interpretation located throughout the precinct. They will include installations of signage artwork and salvaged artefacts accompanied by minor landscape works. Nodes will present narratives developed for the precinct. An installation design will be specific to the node location and will present relevant information. A Node design will be developed with input from specific stakeholders who are situated near to its location.

INSTALLATION TYPES & MEDIA

In addition to the content, the form and material chosen for each installation will play a role in orienting the visitor within the precinct and in relation to the elements that are encountered. It is proposed that a number of interpretive techniques be employed as outlined below.

Salvaged artefacts The precinct includes items of historical significance that reveal prior use and industry in the area. Where possible, these should be kept and preserved in‐situ. Some artefacts may benefit from relocation closer to public interfaces, including sections of pipe and machinery from the Pump Station C site or buildings from the Portagabra site that will be relocated during the Water Treatment Plant works. Salvaged artefacts should include signage that describes use and context as part of the installation.

Signage The scale of the precinct and its topography make it difficult to comprehend when experienced on foot or by car. Signage will provide orientation and direction for visitors by notifying them of attractions and where to access them. Three distinct uses for signage are proposed for the precinct including site identification, way finding and interpretation.

Site identification signage distinguishes significant locations within the precinct and communicates their importance to the visitor. This includes signage such as gateways marking the entrances to the precinct. Way‐finding signage orients the visitor and shows their location within the precinct. Trail markers and directional signs to other significant places are examples of way‐finding signage. Interpretation signage will convey information associated with installations at the proposed nodes.

The National Trust has previously developed a signage strategy marking the weir walk and facilities including the No. 1 Pump Station. The existing signage design uses robust materials and incorporates simple industrial forms with an effective graphic style. New signage should seek to integrate with the existing to convey a unified precinct‐wide approach.

Educational play equipment Aimed specifically at children, educational play equipment combines play with a learning component to make an interpretation message accessible and interactive. Educational play requires custom designed play equipment for use in interactive demonstrations. The target age range of educational play items is generally from 5 to 14 years of age and needs to accommodate small school groups.

Public and community art Public and community art can provide an important means for appreciating place in inventive ways, further increasing the vibrancy of the precinct. Artworks may be incorporated into entries or in

© Ecoscape (Australia) Pty Ltd 7678‐2566‐10R 25

smaller scale works designed for pedestrian encounters. They will allow professional artists the opportunity to contribute to the precinct and inspire curiosity and wonder in visitors.

It is recommended that a Public Arts Consultant be engaged to assist in the formulation of an effective brief and the artist selection process. Allowances for design consultancy and engineering of artworks should also be factored into any public artwork budget.

Community art should also be considered for inclusion in the precinct design. Incorporating community artworks helps to foster stronger connections between place and local community groups, resulting in greater community custodianship of the site. Primary schools, secondary schools and community arts groups are commonly associated with the development of artworks. Establishing a relationship between established artists and community groups may also assist in providing high quality results.

DESIGN GUIDELINES AND MATERIALS

To guide detail design and ensure a consistent treatment for the landscape amenities and interpretive installations it is recommended that design guidelines are prepared for the precinct to define the basic design language for pavements, walls, signage, furniture, bollards and other hard‐ scape elements.

Materials used should be coordinated across projects wherever possible. Materials should be durable, suited to external use and locally sourced where possible. They should aim to meet Environmentally Sustainable Design criteria and convey a uniform design language that extends from the unique character of the site, Suggested materials include:

• Native hardwood timber like recycled Jarrah and marri that may be locally sourced from the Water Treatment Plant and Pump Station C sites • Steel as is currently used throughout the precinct for interpretive signage. Detailing of steel should aim for simple connections and be in keeping with the functional industrial nature of the site. • Concrete that that is robust and durable. It’s innovative use is displayed in the weir wall and it is a versatile material for incorporating imaging techniques for interpretation • Rammed earth that is an abundant material and has a strong connection to the site. • Local stone used for retaining and freestanding walls

7.0 blueprint design 7.1 objectives

The Blueprint design’s objectives are to:

• complement the unique Mundaring Weir landscape character and features • employ an appropriate scale of design • rationalise the arrangement of facilities and amenities • embed environmental and cultural values in the design • integrate practical and sustainable design solutions • provide for universal access • minimise visitor risk through Crime Prevention Through Environmental Design principles • preserve remnant vegetation • create journeys of education and enjoyment • develop amenities with a recreational focus • enhance existing recreational uses • expand and enhance the pedestrian experience • rationalise all vehicular access and parking • integrate water management and planning principles in accordance with Public Drinking Water Source Areas policy.

7.2 design elements

The Blueprint design consists of four main elements:

• Gateways and entries • Precinct hubs • Nodes • Trails

An outline of these elements is provided below.

7.3 gateways and entries

Gateways and entries are experienced primarily by vehicle and are located to assist in the way finding and orientation of visitors within the precinct. They will announce the arrival and departure from the precinct and contribute to the perception of the precinct as a cohesive unit.

© Ecoscape (Australia) Pty Ltd 7678‐2566‐10R 27

GATEWAYS

The precinct has two main gateways located at each end of Mundaring Weir Road in the towns of Mundaring and Kalamunda. Mundaring Weir Road is a popular touring route providing access to the Helena Valley with the weir as its major focus. The gateways will serve to alert visitors to precinct’s location

The gateway from Mundaring is identified at the Sculpture Park where the rail trail crosses the beginning of Mundaring Weir Road. Future upgrades to the Sculpture Park will be coordinated with the Shire of Mundaring. For more information on this gateway refer to Figure 17 Sculpture Park Concept Plan.

The gateway from Kalamunda is located at the intersection of Mundaring Weir Road and Mead Street. This location is also the start of the Bibbulmun Track. At present no interpretive installations are proposed here however new road signage is being installed on Mead Street to provide clearer direction to Mundaring Weir Road. More information on this can be found in the Mundaring Weir Signage Strategy prepared by Tourism Western Australia in collaboration with Mundaring Weir precinct stakeholders and Main Roads.

Figure 9: Gateway Locations

PRECINCT ENTRIES

Three precinct entry locations will be developed in the precinct. Generally entry environment concepts may include low walls, landscaping and public art located at important thresholds. These entry environments will share a common design language through materials and form, and will be constructed at a scale that is legible from the road.

Northern Precinct Entry

The Northern Precinct entry will be located near the intersection of Mundaring Weir Road and Allen Road. The intersection is an important connection point between the Hills Centre, Kookaburra Cinema, proposed DEC offices, proposed Water Treatment Plant and Upper Hub. Presently it lacks a clear direction for the visitor and includes a range of signs vying for attention.

The primary purpose of this entry is to direct visitors to the Upper Hub where parking and amenities are found. The entry design should have an emphasis on the south eastern corner of the intersection to encourage drivers to continue along Weir Village road. Landscape treatments for the roundabout and public artwork are also suggested to enhance the intersection. Detail design of the entry will be determined with further input from the Steering Group.

Locating the interpretive node for the water treatment plant along with an information bay near the intersection is also suggested. This would provide general information to help navigate the precinct.

Figure 10: Northern Precinct Entry

© Ecoscape (Australia) Pty Ltd 7678‐2566‐10R 29

Southern Precinct Entry

The Southern Precinct entry is located at the southern weir wall car park. This parking facility is popular as it affords easy pedestrian access to the weir wall. However, vehicle entry points to the car park are undefined, creating a hazard when large volumes of traffic are exiting and entering Mundaring Weir Road. This entry environment should be designed to mark the entry to the precinct, encourage slower traffic and formalise access to the parking facilities. The upper car park at the terminus of the weir wall is a destination point and includes an interpretive node. It is also considered a location for a public artwork that can define the entry to the precinct.

Lower Hub Entry

A third entry statement is required at the new entry to the Lower Hub off Mundaring Weir Road. This will be incorporated with the works for the new access road. The design of the entry statement may include low landscape walls, with integrated signage and associated landscape plantings of local, dieback resistant native plant species. These works will also require the relocation of the Tourism Australia’s signage for the No.1 Pump Station to this point

Figure 11: Southern Precinct Entry

7.4 precinct hubs

The precinct hubs form the major sites where visitors are introduced to information about the weir and invited to explore further. They are located to facilitate pedestrian access and work with the precinct’s current attractions and the operational requirements of the weir. The precinct falls within the Mundaring and Middle Helena catchment areas and part of the Mundaring RPZ and all proposed works need to be designed, constructed and managed to minimise the contamination risk to the public drinking water source. Consideration should be given to the Department of Water’s Water Quality Protection Note 6 Vegetated buffers to sensitive water resources.

The Blueprint Design identifies two locations that will provide the major focus for visitor interaction. These sites have been chosen as they include existing parking facilities and amenities that, with upgrades, can accommodate larger numbers of visitors. They are also well connected to the trail network and are logical destinations for visitors when driving and walking in the precinct. Development of these sites will create inviting places that engage the visitor directly through interpretive features, landscape design and provision of amenities.

Figure 12: Upper & Lower Hub Locations

UPPER HUB

The Upper Hub is located adjacent to the Rose Garden picnic area, the highest point above the northern end of the Weir. Historically it has been a popular picnicking area due to its high vantage, its close proximity to the top of the weir wall, and its central location within the precinct. The Upper Hub will be the main parking and access point for the weir precinct and will include a range of amenities including toilets, barbeques, picnic tables, shade structures and play equipment. A concentration of facilities at this point is aimed to concentrate visitors in a single location where information about the precinct can be obtained through interpretive installations including maps signage and artwork.

Vehicular Access

The existing vehicular access along Weir Village Road is in fair condition and provides access to both the parking facilities at the crest of the hill and the northern end of the weir wall. Formalisation of the parking adjacent to the Rose Gardens has been designed to maximise capacity and minimise the paving, with priority given to pedestrian movement. This parking area can also accommodate overflow parking for events held at the Weir Hotel as is currently the case. .

Pedestrian Access

Pedestrian access provides circulation from the car parks to the C.Y. O’Connor Memorial, toilet facilities and weir wall. Upgrades to pathways are proposed for the new parking facility adjacent to the Rose Garden, and around the proposed playground and interpretive node locations. These upgrades are to adhere to Disability Discrimination Act (DDA) requirements wherever possible. Disabled access to the northern end of the weir wall will be maintained using the existing weir wall car park.

Future works may include a new pathway along the old railway alignment from the top of the weir wall to the No.1 Pump Station. This will provide a key location for a ‘railway’ themed interpretive node and provide views to the existing and proposed pump stations and pipeline as well as allow for universal access to the base of the weir wall.

Amenity

The Upper Hub design allows for the upgrade and expansion of existing site amenities including the barbeques, shade structures and playground. An allowance has been made to refurbish the existing toilet facilities to include new fixtures, paint and paths.

© Ecoscape (Australia) Pty Ltd 7678‐2566‐10R 32

Vegetation

The Upper Hub concept proposes a reduction in the area of turf. This will reduce the maintenance required for the upkeep of the turf and allow additional planting to be installed around locations such as nodes and playgrounds.

Additional shade tree planting is included around the parking facilities to improve shade. It is proposed that a planting palette consisting of water‐wise endemic species be used to reduce watering requirements and promote Water Sensitive Urban Design principles within the development. However, historically significant exotic species, such as those used in the Rose Garden, should be conserved and maintained as a reflection of the site’s history. Mundaring Weir was a popular day trip destination and these gardens played a critical role in the attraction and comfort of visitors to the area. Information about the significant historic plantings should be incorporated with interpretation at this location

Rehabilitation of the vegetation surrounding the Upper Hub will be carried out using endemic species tubestock. It is recommended that rabbit‐guards be used to deter kangaroos and rabbits from eating the rehabilitation planting before it has become established.

Crime Prevention through Environmental Design (CPTED)

CPTED is the design of environments to minimise the opportunities for crime to occur. Landscape planting has an important role to play in the prevention of crime in outdoor areas. Car security is currently a major concern for visitors. It is recommended that only groundcovers (less than 0.5m high) be used adjacent pedestrian paths and in high‐traffic areas to reduce hiding places. Where larger shrubs are used, they should be planted a minimum of 2.0m from pathways. CPTED principles will be applied to both the Primary and Lower Hubs.

Signage

Under the Blueprint design, the existing directional signage in and around the Upper Hub is to be amalgamated to distil the important information and reduce visual clutter. Road way signage will also be rationalised and landscape elements used to direct visitors where appropriate.

LOWER HUB

The Lower Hub is situated to the south of the Weir Spillway directly across from the No.1 Pump Station, the site of the original workers’ camps for the initial building of the Weir Wall. The Lower Hub is perceived primarily as an access point to the base of the Weir wall, the No.1 Pump Station and National Trust’s educational facilities.

Vehicular Access

Vehicular access to the southern embankment of the Helena River is via an un‐sealed road that joins onto Mundaring Weir Road on an acute bend at the base of the valley. The Blueprint design proposes a new sealed‐road access further along Mundaring Weir Road as a road safety measure to increase visibility and improve driver sight lines. Existing vehicular access north of the spillway will be maintained for Water Corporation authorised access only.

Pedestrian Access

The design of the Lower Hub provides for new DDA compliant pedestrian access to the No. 1 Pump Station that houses the National Trust of WA’s Visitor’s Centre, and between the various facilities within this Hub. These links will ensure public vehicle access to No. 1 Pump Station is maintained during the construction of Pump Station C, which will begin in July 2011.

The ‘Weir Walk’ trail will be articulated and strengthened where it passes through the Lower Hub Area, providing access to the upper weir wall.

Amenity

The existing public amenities within the Lower Hub will be addressed as part of the Blueprint design. A new playground will be installed with potential relocation adjacent to the picnic area to maximise views to the weir wall and No.1 Pump Station; and the existing toilet facilities upgraded.

Vegetation

As with the Upper Hub, the Lower Hub concept proposes a reduction in the area of turf. This will be limited to the entry to the bridge to reduce the maintenance and watering requirements. Endemic species planting will be installed in beds along pedestrian paths and terracing.

Signage

Clear signage will be required at the proposed entrance to the access road off Mundaring Weir Road, and directional signage at key locations will provide orientation and navigational information to reach various facilities. The design of signage will be consistent between the Upper Hub, Lower Hub and the wider precinct.

7.5 nodes

Nodes are located throughout the precinct as sites for interpretive installations. These locations have been identified based on one or more of the following factors:

• historic significance • salvaged artefacts • key access and circulation points • public amenity • future works.

Nodes may take the form of interpretive signage, artworks, salvaged artefacts, public amenity such as bench seating, or a combination of these elements. Broadly, the installations will aim to develop uniform branding to achieve a higher degree of cohesion in the precinct. The detail design of installations should relate to the specific node locations and be developed with input from specific stakeholders.

Installations will be developed in a detailed design phase that will consider materiality, placement, orientation and suitability to the intended audience. Wherever possible their design will engage with the thematic structure developed for the precinct to convey the theme, sub themes and narratives. The proposals will be explored further in consultation with relevant stakeholders during the detailed design process.

Locations of the nodes, and their thematic content are shown in Figure 17: Interpretation Node and Trail Plan & Table 1: Precinct interpretive node thematic decriptions.

7.6 trails

Trails within the Mundaring weir precinct and the greater Helena Valley form an important part of the attraction to the area. The trail network caters to a range of user groups and assists in access management by directing visitors towards attractions and away from restricted areas. Due to the Reservoir Protection Zone the creation of new trails is discouraged.

The blueprint plan aims to use the Weir Walk and O’Connor Trails to facilitate access through the precinct. This will be achieved by prioritising these trails in directional maps and signage throughout the area. They will provide visitors with manageable walking distances and goals within an expected 2 hour round trip from the hubs. Nodes are located to be accessible from these trails and ensure that walkers encounter an interesting broad cross section of the precinct’s facilities and attractions. It is recommended that the Weir Walk and O’Connor trail are clearly presented on maps at both of the hubs.

© Ecoscape (Australia) Pty Ltd 7678‐2566‐10R 37

New trails proposed in the blueprint plan are kept to a minimum in line with the Reservoir Protection zone requirements. They are confined to the Allen Road trail link that will connect the Perth Hills National Park Centre, the new Department of Environment and Conservation Depot and Fred Jacoby Park and greater Beelu trail network.

Rerouting of public access along the old railway alignment below the weir wall should be considered for future stages of work to take advantage of its gentle grade, historic significance and proximity to the new works on Pump Station C.

Long distance regional trails such as the Golden Pipeline Heritage trail which has a terminus within the immediate vicinity of the weir wall at the No.1 Pump Station; and the KEP Track which has a trail head within the hall grounds opposite Mundaring Weir Hotel may be celebrated through interpretive elements. Other trails that pass through the precinct include the Bibbulmun Track and Munda Biddi trail.

Table 1: Precinct interpretive node thematic decriptions Please refer to the Mundaring Weir Water Treatment Plant Interpretation Plan for more detailed information on the Interpretation sub themes and narratives. The narratives have been developed to support the theme for the precinct’s interpretation so they are not finalised at this stage. Modification to the chosen narratives for particular nodes may occur however this should be done with consideration to the overall theme of the precinct.

To ensure effective consultancy in the detail design of the installations, specific stakeholders have been identified as those that are located near each node or have a specific expertise in the subject matter. Their input on the treatment of interpretation will be sought.

7.7 mundaring sculpture park

The Mundaring Sculpture Park is a vibrant and well used public space in the township that attracts locals and visitors. It is a place where community talents are displayed and it provides an important recreational attraction for the area by providing tourist information, parking and trail heads. The blueprint plan aims to strengthen the ties between the sculpture park and the weir in the following ways:

• Installation of the Northern Gateway that highlights the visitor’s entry into the Helena Valley when travelling to the precinct. The gateway is located where several important trails cross Mundaring Road to contribute to the pedestrian and vehicle experience. Interpretive signage and public artwork will highlight these points and the journey to the precinct.

• Upgrades to the trail head signage, including minor landscape works and provision of amenity. The upgrades will key into the thematic interpretive design of the precinct by providing an overview of the trail to the weir and highlighting important historic and environmental elements that will be encountered.

Initiatives for the park are currently being considered as part of the Sire of Mundaring’s master plan for the greater township. Proposals from the blueprint plan may be incorporated into the master plan following further collaboration between Water Corporation and the Shire. Refer Figure 18 Mundaring Sculpture Park for possible interventions to fortify connections between the sculpture park and the weir.

8.0 Program

Water Corporation is committed to implementing the interpretation blueprint by 2014 to coincide with the completion of the water treatment plant and associated works. The following expected timeframes are supplied as a guide to the anticipated design phases and construction phases for consideration in future project planning.

Design Phases are apportioned an indicative duration to cover the anticipated design scope including concept design, community consultation (when required), detail design and documentation. The design phases may run concurrently or sequentially at the discretion of Water Corporation.

Installation phases are apportioned an indicative duration to cover the anticipated works. The actual timing of the work will be subject to change due to the complexity of the proposed works, seasonal planting requirements and clearances from relevant authorities. They will also be coordinated with the construction of the water treatment plant and associated works to avoid disruption in the precinct.
