1. Introduction

Visiting a coastal city during a holiday is among life's most enjoyable experiences. Observing the stunning seascape, walking along sandy shores, and witnessing children playing on the beach create unforgettable moments. This is an experience deeply shaped by its surrounding natural systems. Yet, managing and preserving this natural system—encompassing the sea, dune landscapes, rivers, and coastal vegetation—is complex and demands a coordinated, multidisciplinary approach and a sophisticated planning system.

     The dune system requires protection from surges, rising sea levels, and erosion. Coastal vegetation and the pristine vistas of aquatic landscapes must be safeguarded against uncoordinated development and building heights, while careful vegetation management is crucial for mitigating bushfire risks. Rivers and riparian landscapes require active management to enhance river health, purify runoff water, and prevent the infiltration of floodwaters and pollutants into coastal waters. The management and preservation of green open spaces and landscapes extend beyond their current conditions to ensure future provision and safeguarding of these ecological assets. This underscores the pivotal role of planning tools and mechanisms in integrating diverse disciplines such as landscape ecology, soil and water engineering, flora and fauna conservation, urban design, and architecture. Such integration is essential for sustaining resilient coastal environments in the face of climate-related pressures. This paper examines how South‑West Asian municipalities address these challenges and what lessons can be derived from Victoria’s more integrated planning system. It evaluates how planning systems in Iran and the United Arab Emirates respond to coastal overdevelopment pressures and identifies transferable statutory and strategic tools from comparative systems. In addition to planning tools as tangible outputs, contextual factors such as planning processes and governance regimes are also important; however, this paper focuses primarily on the former. 

     Urban open spaces and foreshore areas are integral components of modern cities, requiring a multifaceted approach to their study and management. This study evaluates planning capacities in selected Iranian and UAE municipalities, focusing on their ability to manage coastlines under increasing development pressure and climate‑related risks. It highlights weak vertical coordination between national agencies and local governments, slow plan updates, and limited statutory tools within municipal systems. The paper then examines the Victorian Planning Provisions (VPP) and local planning schemes, along with associated tools such as strategies, policies, and zoning, in three small coastal cities in Victoria, Australia. The study highlights the importance of interdisciplinary collaboration among landscape architecture, urban planning, and engineering in optimizing natural environments, particularly in Victorian coastal cities, and demonstrates how these insights can inform South-West Asian contexts.  These spaces facilitate movement and interaction within the city, foster citizen engagement, and maintain clean, livable urban areas. They also play a crucial role in preserving biodiversity and protecting coastal areas and urban rivers from erosion. By examining case studies, this paper highlights how planning schemes in the Victorian Planning System help facilitate coordinated efforts among various disciplines and enhance the sustainable management of natural environments in Victorian coastal cities.

1.1. Role of Urban Green Spaces in Coastal Planning and Management  

Emphasizing the multifaceted role of landscapes, this paper argues that urban open and green spaces are vital in addressing ecological and environmental challenges such as flood management, bushfires, and pollution reduction, beyond fulfilling aesthetic preferences, especially in foreshore and coastal areas. In line with later findings, the section reinforces that coastal landscapes must be understood as ecological infrastructure that delivers critical services—erosion control, water filtration, hazard mitigation—particularly under accelerating climate pressures.  The section also highlights the importance of strategic urban planning tools, such as structural plans, as well as statutory planning tools and regulatory frameworks, in predicting, preserving, and enhancing these spaces by embedding environmental data directly into day-to-day decision-making. The paper focuses on urban planning practices in coastal cities of Australia—particularly the Victorian Planning Provisions (VPP)—to illustrate how effective planning and management of natural environments and green spaces can mitigate climate crises and contribute to the overall well-being of urban residents. These examples are used not as direct comparators for Iran and the UAE but as analytical lenses demonstrating how statutory–strategic integration can operationalize environmental protection in coastal contexts. The paper aims to address two specific questions:

1.       What planning tools are available in coastal cities' planning schemes to predict and preserve urban open and green spaces in coastal city development?

2.       What role can these spaces play in managing and preparing cities for climate change challenges, such as floods, bushfire risks, and environmental degradation and pollution?

2. Methodology

The study employed a mixed-method approach, combining desktop research across all cases with field visits to the Victorian cities. The analysis and understanding of coastal-landscape planning and management in the selected cases were informed by both academic research and the authors’ practical knowledge of planning systems in Australia and South-West Asia. Planning practice often relies on forms of professional judgment that cannot be fully captured through standard analytical devices such as comparative tables or spatial models. Following Polanyi’s (2009) concept of tacit knowledge, practitioners frequently “know more than they can tell”; their expertise is grounded in embodied, experiential, and situation-specific forms of knowing. Schön (1991) similarly argues that professional practice operates through reflection-in-action, in which planners and designers make informed judgments while engaging directly with complex and evolving problems. This paper, therefore, draws upon both formal analytical methods and practice-based knowledge, recognising that each provides complementary epistemological insights.

2.1. Case Selection Criteria 

·     Coastal sensitivity (dune systems, estuaries, marine ecosystems).

·     Evidence of development pressure documented in governmental or academic sources.

·     Availability of statutory mapping layers (e.g., overlays, zones).

·     Feasibility of fieldwork between 2023–2024 and access to relevant local authorities.

2.2. Data Sources

The study analysed ten statutory maps and overlay schedules, three Victorian planning schemes, two Iranian coastal management plans (the SMP and JICA plans), and key UAE strategic plans relevant to coastal development.

2.3. Fieldwork

Field visits were conducted in Warrnambool, Port Campbell, and Lorne in 2023–2024. Observations were recorded using a structured template capturing (1) landscape features, (2) evidence of hazard management, (3) visible effects of overlays, and (4) community–environment interactions to ensure consistency across sites.

2.4. Data Analysis

All materials were analyzed using a thematic coding framework, with categories including ‘hazard management’, ‘ecological protection’, ‘statutory tools’, ‘development pressure’, and ‘municipal capacity’. Cross‑case comparison identified recurring patterns and divergences that informed the synthesis presented in later sections.

3. Tools for Urban Planners to Predict, Plan, and Manage Urban Open Spaces and Coastal Areas

Urban open and green spaces, despite their numerous benefits, often face vulnerability in traditional planning systems, which are primary tools used by urban planners to forecast and guide future land use. Traditional instruments, such as Comprehensive and Detailed Plans, tend to treat green spaces as static land-use patches, limiting their potential as dynamic ecological infrastructure. These plans also struggle to adapt to the evolving urban conditions and frequently overlook the ecological functions of open spaces—such as flood mitigation, stormwater management, and habitat connectivity—while failing to incorporate innovative approaches like water-sensitive urban design and integrated green-blue planning.

     This raises the question: What tools do different countries employ to maintain environmental quality in cities and to predict and secure the open and green spaces needed for citizen wellbeing, recreation, and ecological resilience? To address this, the paper explores a spectrum of planning instruments—including strategic and structural plans, policies, green-space banks, development-linked contributions, and agreements with developers used in Victorian coastal cities. It also examines how zoning and overlays impose statutory controls on future development and protect various categories of green and coastal landscapes. The following sections outline these tools and demonstrate their application through international case studies, highlighting contrasts between South-West Asian practices and the integrated statutory framework used in Victoria.

3.1. Urban Planning in Coastal Cities: A brief review of some South-West Asian case studies

3.1.1. Urban Planning in Northern and Southern Coastal Cities in Iran

Iran has nearly 5,000 km of coastline along the Oman Sea and the Persian Gulf, and over 800 km along the Caspian Sea. Over the past three decades, these coastal regions have experienced rapid development, underscoring the urgent need for an integrated, comprehensive shoreline management strategy to optimize resource use and mitigate the negative impacts of development activities. According to Dibajnia et al. (2012), urban planning in Iran’s coastal areas emphasizes Integrated Coastal Management (ICZM) strategies, such as the national Shoreline Management Plan (SMP), to address development pressures and promote sustainable resource use. This approach involves creating hazard maps, identifying ecosystem threats, and integrating social, economic, and environmental criteria into land-use decisions, thereby minimizing impacts on coastal zones along the Persian Gulf, Oman Sea, and Caspian Sea. A national SMP was developed for Iran’s Ports and Maritime Organization (PMO) to address current coastal challenges and guide sustainable development policies. The SMP comprises two key components: Hazard Management and Ecosystem-based Development Management. As part of this framework, coastal hazard maps identify vulnerable areas and outline appropriate management responses. Additionally, the plan highlights both opportunities and risks along Iran’s entire coastline to support informed decision-making and sustainable planning within the context of the Environmental Management Plan. One challenge in implementing the SMP is that the PMO remains the primary authority responsible for its execution. It remains unclear how local municipalities— particularly in northern coastal areas, which face greater development pressure due to favorable climate conditions—can effectively participate in or implement the plan.

     A similar challenge persists across the southern coastal regions of Iran.  For example, a study by Gharibreza et al (2022) examined how Bushehr’s local government attempts to apply SMP concepts to the protection of physical space and land-use planning. It involved municipal bodies such as the Ports and Maritime of Bushehr Province and the Coastal and Port Engineering Department of Bushehr Province. The study analyzed environmental, infrastructural, and human factors across different management units (e.g., sedimentary cells). This suggests an emerging local implementation effort to align with SMP policies (especially in southern cities). There is a “Master Plan for Environmental Conservation and Management of Southern Coastal Areas of the I.R. Iran (Case Study Hormozgan)” developed with JICA (Japanese cooperation). The plan covers several municipalities/counties (Bandar Abbas, Bandar Lengeh, etc.), noting stakeholder involvement and mechanisms for implementation, monitoring, and evaluation (Islamic Republic of Iran, Department of Environment, 2020). The approach implies that local (municipal or county) governments are intended to be active participants, although actual implemented outcomes remain insufficiently documented. 

     The examples from the northern and southern coastal areas of Iran highlight a significant gap in the management of land use and the implementation of coastal plans through the planning system. Municipalities in Iran are often not equipped with adequate planning tools to effectively process development applications or land-use permits that could mitigate risks such as flooding, sea-level rise, bushfires, and pollution. Master Plans and Detailed Plans used by municipalities mainly focus on zoning, which leaves gaps in both policy and procedural perspectives when assessing development applications or land rezoning and regulations. Planners cannot directly apply high-level strategic plans prepared by other authorities, such as the PMO, to local development decisions. Referrals to other responsible authorities often result in a fragmented and non-strategic approach, relying on reactive, short-term, non-transparent, and non-participatory processes that prioritize market interests over environmental protection. The following table summarizes some of the challenges faced by municipalities in several northern coastal cities of Iran (Table 1).

Table 1. Northern Coastal Cities in Iran – Municipal Challenges

3.1.2. Urban Planning in the Coastal Areas of the UAE

While UAE masterplans—such as the Dubai Urban Master Plan 2040—promote sustainability, coastal development has historically prioritised real‑estate value over ecological protection. Large‑scale reclamation projects illustrate tensions between economic and environmental objectives. Advanced tools such as remote sensing and spatial mapping are now more widely employed to monitor habitats and guide development away from ecologically sensitive areas. Key strategies include creating ecological buffer zones, promoting universal accessibility, and establishing beachfront guidelines that account for economic, social, and environmental factors. Strategic frameworks such as the Dubai 2040 Urban Master Plan and regulations like the Abu Dhabi Beach Guideline provide guidance to enhance sustainability and optimize resource use in coastal zones (Dubai Municipality, 2022) (Fig. 1).

     However, while these planning frameworks emphasize sustainability and ecosystem protection, actual development practices have often prioritized economic growth, tourism, and real estate value over environmental constraints. The UAE’s rapid coastal urbanization— particularly in Dubai and Abu Dhabi—has been driven by efforts to diversify the economy beyond oil. Luxury coastal developments, including Palm Jumeirah, The World Islands, and Saadiyat Island, were designed to attract global investment and tourism, often resulting in significant environmental alterations. These projects have generated immense revenue but caused major ecological disruptions, including habitat loss for coral reefs, mangroves, and marine species. Most luxury developments are built on reclaimed land, created by dredging and reshaping the seabed. This process:

•      Increases turbidity, harming coral and seagrass beds.

•      Alters coastal currents and sedimentation patterns.

Leads to erosion and long-term instability of natural coastlines.

     The UAE’s policy language promotes sustainability, but economic imperatives—especially luxury real estate and tourism—have historically driven large-scale coastal alteration. However, recent initiatives indicate growing recognition of the ecological damage and a gradual move toward more balanced coastal management (Fig. 2).

Figure 1. The northern coasts of Iran have been occupied by semi-private (parastatal) entities. The image illustrates how urban development has aggressively encroached on coastal areas, putting the dune landscape and coastal ecosystem at risk from various forms of pollution and biodiversity loss. (Source: Islamic Republic News Agency, 2022).

Figure 2. Luxury coastal developments, including Palm Jumeirah, are designed to attract global investment and tourism, often resulting in significant environmental alterations (LCRE Dubai, 2025).  

     Dubai has implemented a Coastal Zone Monitoring Programme since 1997, beginning along the Jumeirah frontage and later expanding to cover the entire extent of the Dubai coast, from Al Mamzar Lagoon to the Jebel Ali coastline. The monitoring has recorded the impacts of coastal development, including the construction of two breakwaters, changes to dune landscapes, and sedimentation along the beaches (Messina Project, 2005)  (Fig. 3).

     The Dubai Urban Master Plan 2040, prepared by Dubai Municipality in 2022 and endorsed by the Vice President and Prime Minister of the UAE, projects a population of 5.8 million residents and 964,000 daily visitors by 2040. The plan aims to double the city’s public park areas, establish a moratorium on additional offshore reclamation, limit the scale of future coastal and creek-side development, and strengthen open space connections along the shoreline and the creek (Dubai Municipality, 2022) (Fig. 4).  

Figure 3. Aerial photographs showing changes in Jumeirah frontage for (left to right) 1981, 1991, 1996, and 2002 (Messina Project, 2005).

Figure 4. Dubai Structure Plan 2040 identifies a range of spatial policies, including land use and built form, housing, heritage, arts and culture, environment and open space, mobility and access, utilities, and governance. It also proposes the establishment of an integrated geospatial data platform Source: (Dubai Municipality, 2022). 

     Dubai’s general beach planning and design guidelines (Dubai Municipality, 2023) outline the uses, minimum width, and setbacks for beaches and all waterfronts in Dubai’s islands, mainland areas, and inland waterways (Fig. 5). 

Figure 5. Map of Dubai's waterfronts based on typology. Note: Subject to update, based on information received up to January 2022 (Dubai Municipality, 2023).

     These plans and guidelines are valuable documents that support more sustainable and environmentally sensitive planning and management of coastal areas by the municipality. However, because they exist as separate PDF documents, they can be difficult for planners to access, navigate, and interpret in their daily work. This fragmentation highlights the need to consider alternative approaches. While recent monitoring programs signal a growing institutional shift toward integrating ecological datasets, these efforts remain outside a unified statutory framework, limiting day‑to‑day enforcement. Victorian planning schemes address this challenge by integrating long-term strategic documents with the statutory provisions and regulations used in day-to-day decision-making. This integration, delivered through a web-based and publicly accessible system, has significantly advanced planning practice. The following sections of this article elaborate on how this model offers important lessons for coastal planning.

3.2. Comprehensive and Strategic Plans and Tools for Urban Open and Green-blue Spaces in Victoria

Some cities implement comprehensive or strategic plans specifically tailored for their urban green spaces. These plans play a crucial role in solidifying the position of urban open and green spaces, ensuring their independence and protection against easy conversion to other land uses. They encourage cities to view green spaces not merely as isolated patches but as interconnected networks and integral components of urban infrastructure, fostering a long-term perspective on their preservation and development. Such plans define the role of these spaces in urban expansion, emphasizing their significance as pedestrian and ecological networks. One exemplary case is the Beijing Green Space Master Plan in China. Covering an area of 16,807.8 square kilometers with a population of about 13.8 million people, Beijing Province has implemented a comprehensive master plan based on ecological landscape principles. This plan provides a holistic conceptual framework for developing urban green spaces across regional, urban, and neighborhood scales to ensure long-term sustainability (Feng Li et al., 2005; Sun et al., 2021).

      At the regional level, the plan preserves natural and semi-natural forests in the northwest and establishes an ecological buffer belt in the southeast to maintain environmental quality and wildlife habitats. At the urban scale, a network of green spaces, including green wedges, parks, and corridors, is proposed. This network not only limits future urban development but also enhances environmental quality and serves as wildlife habitats and migration routes. At the neighborhood level, greenways along rivers, roads, parks, and vertical green spaces are expanded and interconnected, providing recreational spaces near residential areas. This three-tiered approach creates a cohesive ecological network vital for Beijing's sustainable development. By integrating urban parks, forests, grasslands, water bodies, and infrastructure coherently, the plan aims to transform Beijing into an eco-city, aligning with the objectives of the "Green Olympic City 2008" initiative. Over the past decade, Beijing's urban area has expanded continuously, surpassing the developable area specified in the 1992 urban master plan and encroaching extensively on agricultural lands. Residential constructions around satellite towns between the city center and suburbs have been a primary driver. From 1992 to 2002, Beijing's residential area increased by 25%, while agricultural land decreased by 32%, significantly reducing green spaces and compromising ecosystem services.

     Given these challenges, cities are increasingly adopting separate comprehensive and strategic plans to better manage and protect their vital urban open and green spaces. These areas are among the most fragile yet essential in urban planning. An example of such a strategic green space plan is the Central Melbourne Green Space Strategy. Victorian planning schemes integrate strategic policies (MPS, PPF) with statutory controls (zones, overlays) in a single online format (Victoria, Department of Transport and Planning, 2025a). This structure enhances transparency, supports continuous updates, and enables direct alignment between long‑term strategies and daily permit decisions. In Victorian cities, planning schemes serve as regulatory frameworks under the Planning and Environment Act 1987, tailored to each local government area's unique needs and characteristics. These schemes integrate strategic goals and directions with policies, combining elements traditionally found in comprehensive plans such as zones and structure plans. This integrated approach provides a cohesive framework where long-term objectives align with specific policies, systematically guiding land use and development. Planning schemes are available online and follow the same structure and template for all Victorian cities, as defined under Ministerial Directions in the Forms and Content guidelines. This makes them very easy to review, update, and ensures the process is efficient and transparent. Key purposes of Victorian planning schemes include:

1.       Zoning and Land Use Controls: Dividing land into zones (e.g., residential, commercial, industrial) with specific permitted uses and development controls to manage urban growth and protect sensitive environments.

2.       Development Standards: Setting standards for building heights, setbacks, open space requirements, and design elements to ensure new developments integrate with existing landscapes.

3.       Environmental Protections: Incorporating overlays and controls to protect natural features like waterways, wetlands, vegetation, and biodiversity. These measures restrict development in sensitive areas and promote sustainable land use.

4.       Heritage and Cultural Preservation: Including overlays to conserve historic buildings, landscapes, and areas of cultural significance, ensuring development respects and enhances heritage values.

5.       Infrastructure Planning: Integrating provisions for essential infrastructure such as transport networks, utilities, parks, and community facilities to support new developments.

6.       Community Engagement: Outlining processes for community consultation and participation in planning decisions to ensure residents and stakeholders contribute to shaping their neighborhoods.

     In summary, Victorian planning schemes provide a comprehensive set of tools for managing land use, protecting the environment, conserving heritage, planning infrastructure, and engaging communities in the planning process. These instruments are crucial for promoting sustainable development and enhancing the quality of life across Victorian cities. This paper examines how these combined structural and strategic frameworks integrate environmental values through overlays, zones, and additional mechanisms such as Development Contribution Plans (DCPs) and Public Open Space Contributions (POSCs). Each planning scheme incorporates a Municipal Planning Strategy (MPS) and a Planning Policy Framework, which set out high-level directions, strategies, and policies to guide environmental and landscape management, natural resource protection, and risk mitigation within each municipality. Environmental and landscape values encompass various types of open spaces and landscapes, including marine and coastal environments, water bodies and wetlands, alpine areas, and other significant landscapes and environments (Fig. 6 & Fig. 7).

3.2.1. Structural Plans, Development Contribution Plans (DCP), and Public Open Space Contributions (POSC)

In addition to comprehensive and strategic plans, urban areas rely on sectional plans like structural plans to guide and manage future development. These documents outline the framework for specific areas—be it residential zones, commercial centers, or tourist districts—often supplementing the city's comprehensive plan or Planning Scheme in Victoria, Australia. Structural plans include provisions for green spaces as integral components of development. They ensure developers adhere to designated land use policies and regulations, integrating green spaces from the outset to preserve their ecological, social, and aesthetic values. Development Contribution Plans (DCPs) and Public Open Space Contributions (POSC) are crucial tools in urban planning (City of Melbourne, 2012). They mandate developers to enhance public infrastructure, including green spaces, as part of development approvals. DCPs specify financial contributions to fund necessary infrastructure, supporting urban growth with adequate amenities (Victoria, Department of Transport and Planning, 2025a). POSC requires a portion of developed land to be allocated for public open spaces or mandates financial contributions for their creation and maintenance elsewhere in the city. This ensures urban expansion meets community needs for recreation and environmental conservation. By integrating structural plans, DCPs, and POSC into urban planning, cities can effectively manage and safeguard their green spaces. These tools promote sustainable and livable urban environments where green spaces are prioritized as essential infrastructure.

1.       Needs Analysis: Initially, the needs and priorities for urban open and green spaces are identified. This may include public gatherings, recreational areas, parks, squares, etc.

2.       Design and Planning: After accurately understanding the needs, open and green spaces are designed. This design includes zoning areas, types of plants, recreational equipment, urban furniture, and other components related to open spaces.

3.       Resource Allocation: The DCP is created to secure financial resources for various project implementations. Resources may cover construction costs, equipment, maintenance, and management.

4.       Forecasting: Based on the created plans and maps, various forecasts are made, such as area alignment, environmental impacts, population density, traffic, etc.

5.       Implementation and Follow-up: After resource allocation and forecasting, the process of implementing open and green space projects begins. This may involve constructing and installing equipment, planting vegetation, building pathways, etc. Continuous monitoring and follow-up are also crucial to ensure the objectives are met and the spaces are used effectively.

6.       Evaluation and Improvement: Over time, urban needs and conditions may change. Therefore, DCPs and open space projects require ongoing evaluation to make necessary improvements and adapt to urban changes.

     DCPs play a crucial role in urban planning by creating and preserving open and green spaces, contributing to a beautiful, healthy, and recreational environment for city residents. Another effective tool for planning and implementing green spaces in residential areas is the Public Open Space Contribution (POSC). Under this framework, developers preparing and subdividing land are required to allocate 5% of the land area or its equivalent value to the urban management authority. These financial contributions are earmarked for creating or enhancing public open spaces such as parks, squares, walking paths, and recreational areas within the locality. POSC ensures that urban development mitigates its environmental impacts and supports community wellbeing, aligning with regional urban development plans and regulations (Fig. 8).

Figure 8. Clyde Creek Precinct Structure Plan. In this plan, green spaces have established their position as the primary framework, not an additional or overlooked element in the city structure (Victorian Planning Authority, 2015).

3.2.2. Utilizing Zones and Overlays as Statutory Planning Tools for Managing Open Spaces and Coastal Landscapes 

Open and green spaces in urban areas serve multiple functions beyond social and recreational roles. They can prioritize the conservation of native plant species and ecological integrity over purely aesthetic or leisure values. These environmental and ecological aspects often transcend conventional green space categories on urban maps. To address these diverse roles, urban planning in Victoria, Australia, employs supplementary tools such as zones and overlays within planning schemes. These overlays are specifically applied to open space areas like parks, foreshores, and riverbanks to highlight their unique attributes. These may include scientific research significance, ecological importance, historical value, or aesthetic appeal (Victoria, Department of Transport and Planning, 2025a). For example, areas with historically significant trees might be protected by a Heritage Overlay, ensuring their preservation alongside other environmental considerations. These zoning and overlay tools are essential in managing and protecting Victoria's open and green spaces effectively. Some of the zones and overlays used in urban planning for open and green spaces in Victoria include:

·       Environmental Significance Overlay (ESO): Applied to green spaces with environmental and ecological value, such as wetlands and coastal green spaces, or

·       green areas that play a role in soil stabilization.

·       Public Park and Recreation Zone (PPRZ): Emphasizes the recreational and leisure features of parks and green spaces. For example, the Shah Goli Park in Tabriz is considered an open and green space of this type.

·       Significant Landscape Overlay (SLO): Focuses on important aesthetic, cultural, or historical features of a landscape. Historical gardens or natural landscapes like the Ein Ali Mountains are examples of such open spaces.

·       Urban Floodway Zone (UFZ): Defines areas prone to flooding during heavy rainfall seasons, identifying them for specific management to mitigate flood risks.

·       Biodiversity Conservation Zone (BCZ): Identifies green spaces with biological significance and endangered species. These areas might include native plants that are more resilient to the local climate or create suitable ecosystems for local wildlife, such as specific flowers that endangered butterflies rely on for their habitat.

     The use of zones and overlays in urban planning allows planners to preserve and manage green spaces based on their distinctive characteristics and values. This approach integrates ecological, historical, and recreational considerations into urban development, fostering sustainable city planning. The following section illustrates how these overlays have been applied in three coastal cities in Victoria to protect their natural environments and foreshores. This initiative aims to balance aesthetic, social, and ecological attributes while ensuring the ecological functions of urban open and green spaces and managing flood risks. The cities are selected here because the author has visited all of them and, therefore, their review is not solely based on desktop research but also relies on lived experience. They are smaller in size and population than the South-Asian cases discussed earlier, but the goal is not to compare them directly. Rather, they serve as concrete examples demonstrating how statutory tools—particularly zones and overlays—function in practice to shape, protect, and manage coastal landscapes and can offer transferable insights applicable to the South-West Asian cases. 

4. Victorian Case Studies: Warrnambool, Port Campbell, Lorne – Using overlays to manage complex environmental and landscape challenges 

The three Victorian cities studied operate under different landscape conditions yet use similar overlay tools—ESO, SLO, BMO, LSIO—to manage environmental and landscape risk. Table 2 summarizes key features. Field evidence confirms that these tools shape vegetation management, development setbacks, dune protection, and hazard mitigation. Located along the iconic Great Ocean Road—one of Australia’s most scenic coastal corridors—these settlements provide a clear view of how statutory planning tools operate within complex, high-value coastal landscapes. Their shared geography allows the study to trace how overlays respond to different environmental pressures while maintaining consistent regulatory intent across municipalities (Fig. 9).

Figure 9. Warrnambool, Port Campbell, and Lorne, three coastal cities along the Great Ocean Road in Victoria, Australia (Joogo Style, n.d.).

     Three cities along this corridor, including Warrnambool, Port Campbell, and Lorne, are selected for a detailed examination of their coastal landscapes and the application of overlays and Victorian Planning Provisions (VPP) tools for their management. The information and data for these cities are collected from their planning schemes and overlay maps, which are publicly available through the Department of Transport and Planning website: https://www.planning.vic.gov.au/planning-schemes

A site visit to each city, particularly to their coastal landscapes, was also undertaken between 2023 and 2024.

     Located on Victoria's southwest coast, Warrnambool is home to approximately 35,000 residents. It's known for its rich maritime heritage, highlighted at Flagstaff Hill Maritime Village. The city attracts tourists with its scenic Lady Bay, popular for whale watching and beach activities. Tower Hill Wildlife Reserve offers opportunities to explore volcanic landscapes and spot native wildlife like koalas and emus (Victoria, Department of Transport and Planning, 2025b). Port Campbell is a quaint coastal town with around 400 residents, which is famed as the gateway to the Twelve Apostles. Tourists flock here to witness these iconic limestone stacks, along with other natural wonders like Loch Ard Gorge and the rugged cliffs of Port Campbell National Park. The town offers a quiet base for exploring the dramatic coastal scenery of the Great Ocean Road (Victoria, Department of Transport and Planning, 2025c).

Lorne is a vibrant seaside town with about 1,200 inhabitants located in the Surf Coast Council. It's a popular beach destination renowned for its surf culture, annual Pier to Pub swim race, and scenic attractions. Visitors enjoy the Great Otway National Park's lush rainforests and waterfalls, such as Erskine Falls, as well as panoramic views from Teddy's Lookout over the rugged coastline and Great Ocean Road (Victoria, Department of Transport and Planning, 2025d).

     Table 2 summarizes the landscape features of these three cities and the relevant overlays used to control and manage their environmental values, excluding considerations of flooding, integrated water management (IWM), and water pollution, as these primarily affect off-site coastal areas, rivers, catchment areas, and city drainage networks. Urban open and green spaces serve a crucial yet often overlooked role in urban flood management. Cities face persistent challenges with flooding, exacerbated by impermeable surfaces like asphalt and waterproofed rooftops that prevent natural water absorption. In contrast, the concept of a "sponge city" and Water Sensitive Urban Design promotes urban areas designed to absorb rainfall, reducing surface runoff and filtering pollutants such as phosphorus, nitrogen, and fine metal particles. This approach not only mitigates flooding but also purifies stormwater, facilitating water recycling and conservation. However, the aspect of purifying and filtering stormwater before it enters urban rivers, lakes, and wetlands receives less attention from urban planners, designers, and landscape architects. While water-sensitive urban design has gained recognition for flood control, water retention, and aesthetic improvements, its focus often neglects water purification and recycling. Urban green spaces are pivotal in managing water pollution by absorbing harmful substances, particularly nitrogen. Without filtration and purification before directing surface water into urban drainage networks, it poses risks to landscapes and coastal environments. To resolve this, several methods have been invented in Australian cities. These include using sand filters for sediment capture, rain gardens, infiltration trenches, detention basins, and other techniques to delay water movement, allowing it to gradually seep into lower layers before being directed into the urban drainage system. All these methods fall under Integrated Water Management (IWM), a policy attached to Planning Schemes in the state of Victoria, Australia. Urban planners and designers are required to consider this approach in controlling and guiding urban development (Fig. 10).

Figure 10. illustrates various water-sensitive urban design strategies for managing surface water retention and flood control through the use of green spaces and permeable surfaces (Wong et al., 2020).

Table 2. Three Victorian Coastal Cities, the landscape features, and overlays used to manage them

4.1. Warrnambool, a city by the ocean

Warrnambool, celebrated for its stunning ocean vistas, expansive sandy beaches, and scenic trails, has been actively revegetated by the Department of Environment, Energy, and Climate Action (DEECA) to safeguard its dune system from erosion. These dune systems—especially those around Lady Bay and the Merri Marine Sanctuary—function as critical natural infrastructure that buffers the coast from storm surges, maintains beach stability, and supports ecological diversity (Fig. 11).

Figure 11. ESO and SLO are used to protect the coastal landscape in Warrnambool, covering areas along Lady Bay Beach from Breakwater to Logans Beach (Victoria, Department of Transport and Planning, 2025b).

     Adjacent to Warrnambool Foreshore, Lake Pertobe serves as a recreational and ecological green space covered by the Environmental Significance Overlay (ESO). It plays a crucial role in Integrated Water Management (IWM), purifying collected and filtered runoff water from the city's drainage system. This dual function supports the lake as a habitat for numerous species while also preventing pollutants and floodwaters from entering the sea. Nonetheless, the coastal landscape remains a contested space, utilized by various groups for different purposes. Surfers and swimmers relish the water, horse riders wash their steeds in the sea, and some residents often view the newly vegetated landscape as an obstruction to their oceanic views, occasionally advocating for the removal of parts of this picturesque environment. This underscores the inherent complexity of managing such a multifaceted setting, necessitating a delicate balance between ecological preservation and accommodating the community's diverse interests. Warrnambool, known for its attractive ocean views, large sandy beaches, and trails, has been revegetated by the DEECA to protect the dune system from erosion. The dune system, particularly around Lady Bay and the Merri Marine Sanctuary, plays a critical role in coastal protection and biodiversity. These dunes act as natural barriers against coastal erosion and storm surges, safeguarding inland areas and maintaining beach stability (Warrnambool City Council, 2024) (Fig. 12).
