<a href="https://www.apartments.com.au/developers/draycon">Draycon Building</a> is nearing completion of Boutique Chevron Island, a 42-apartment development on the northern end of Chevron Island at 17–19 Parneno Street, with a limited-time offer of fully furnished apartments available.

Now more than 90 per cent complete, <a href="https://www.apartments.com.au/buildings/boutique-chevron-island-17-19-parneno-chevron-island-qld-4217">Boutique</a> has been shaped by one of the Gold Coast’s most tightly held island addresses, where riverfront outlooks and walkable access to Surfers Paradise converge.

For Draycon Building Managing Director Howard Dabit, the appeal of the site was immediate.

“I knew it was a good site as soon as I saw it,” Dabit said.

“The position and location on the north end of <a href="https://www.apartments.com.au/developments/chevron-island-qld-4217">Chevron Island</a>, the way the river swirls around the site basically from the north to the east, it feels like the site is surrounded by the water. The height that we’ve got and the aspect looking north is beautiful. Eighty per cent of the apartments are looking north so they get that drenching sunlight coming in.”

[smartcode_project:default project_id=89709 project_image_fid=360922]

That northern orientation places the development within a stretch of Chevron Island defined by open river aspects and skyline views, while remaining embedded in the suburb’s established village setting.

Chevron Island has increasingly drawn owner-occupiers seeking centrality without the intensity of high-rise beachfront living. Positioned at the geographical centre of the Gold Coast, the island offers direct access to both the beach and key cultural infrastructure while retaining a neighbourhood-scale character.

Connected by bridge to Surfers Paradise, Chevron Island offers walkable access to beaches, riverfront parklands and a revitalised foreshore boulevard animated by walkers and cyclists throughout the day. The Pacific Ocean is only minutes away, reinforcing the suburb’s dual river-and-surf identity.

At the same time, Thomas Drive forms the spine of the island’s village life, delivering cafés, wine bars, casual dining and everyday services within easy reach. Independent grocers, wellness operators and neighbourhood retailers contribute to a community atmosphere that remains distinct from the vertical scale of the beachfront.

[smartcode_project:default project_id=89709 project_image_fid=360915]

In the opposite direction, the Green Bridge links directly to HOTA – Home of the Arts – placing galleries, performance venues and parklands within walking distance. Weekly markets and major exhibitions draw visitors from across the region, while residents return to a quieter residential pocket at day’s end.

Public transport, including nearby bus routes and the G:link light rail corridor along the coastal spine, strengthens connectivity north and south. Griffith University, the Gold Coast University Hospital precinct and established private schools such as The Southport School are all within a short drive.

Ongoing investment across Surfers Paradise, HOTA and the broader Southport corridor has elevated amenity while preserving Chevron Island’s comparatively low-rise residential character. It is this balance, walkable village atmosphere paired with metropolitan-scale infrastructure, that continues to differentiate the suburb from higher-density beachfront precincts.

Boutique comprises just 42 residences, designed to maximise river and skyline outlooks within this tightly held island setting.

Boutique Chevron Island is slated for completion in April 2026, with prices starting from $1,220,000.

Sydney developer <a href="https://www.apartments.com.au/developers/deicorp">Deicorp</a> has secured planning approval for a $300 million residential development in Lindfield, marking the company’s second project on Sydney’s North Shore and its first on the Upper North Shore.

Located on Beaconsfield Parade and designed by DKO Architecture, the state significant development comprises three buildings of up to 10 storeys and will include 399 residences, including 59 affordable homes and 40 adaptable homes.

Residences will range in size from one, two and three bedrooms, with two-bedroom apartments accounting for over 60 per cent of the product make-up. Residents will have access to a broad suite of amenities, including a wellness area, indoor and outdoor recreational spaces, a pool, a gym, a community room and a golf simulator.

In line with Deicorp’s long-standing focus on creating transit-oriented communities, the project is located just 260 metres from the Lindfield Train Station, reinforcing its role in delivering well-connected housing close to established infrastructure, retail and local services.

The inclusion of affordable and adaptable housing supports greater diversity within the local market, while the mix of apartment types responds to demand from downsizers, young professionals and families seeking access to the Upper North Shore.

Deicorp Founder Fouad Deiri OAM said the approval represents an important milestone for both the company and the suburb

“This approval allows us to deliver well-designed homes in a location that is already supported by strong transport and community infrastructure," Deiri said.

"Our focus is on creating places that integrate into their surroundings and provide long-term value for residents, and the broader Lindfield community. Being within walking distance of the station ensures this project supports sustainable growth in the right locations."

Across its portfolio, Deicorp currently has 4,703 apartments under construction, playing a leading role in shaping connected, liveable communities across Sydney.

Its expanding portfolio of Metro-linked developments includes Tallawong Village, <a href="https://www.apartments.com.au/new-apartments/kings-bay-village-five-dock-53-75-queens-road-five-dock-nsw-2046">Kings Bay Village</a> in Five Dock, <a href="https://www.apartments.com.au/new-apartments/hyde-metropolitan-sydney-133-141-liverpool-street-sydney-nsw-2000">Hyde Metropolitan</a> in Sydney CBD, <a href="https://www.apartments.com.au/new-apartments/falcon-alexander-crows-nest-8-alexander-street-crows-nest-nsw-2065">Falcon &amp; Alexander</a> in Crows Nest and Showground Village, Castle Hill.

Deicorp purchased the Beaconsfield Paradise site last year. Construction is scheduled to commence in Q2 of 2026 and will be completed in 2029.

In a joint venture with The Trump Organization, Australia developer Altus Property Group has announced plans to bring a Trump International Hotel &amp; Tower to the Gold Coast, marking the first Trump-branded project in Australia.

"Trump International Hotel &amp; Tower, Gold Coast is our first official project in Australia and reflects our unwavering commitment to delivering world-class luxury experiences in iconic locations around the world," Eric Trump, Executive Vice President of The Trump Organization, said.

"This development exemplifies the Trump brand’s dedication to quality, sophistication, and unmatched service, and we are thrilled to bring this vision to the vibrant Gold Coast community."

The 91-storey building, which will become the tallest in Australia at 335 metres, will feature a&nbsp;285-room luxury hotel bearing the trademark Trump logo. It will also include 272 luxury residential apartments, a three-level podium with an exclusive Beach Club, and over 3,400 sqm of premium commercial, retail, and dining space, revitalizing the central Surfers Paradise precinct.

“Trump International Hotel &amp; Tower, Gold Coast will be a truly unique offering in the Australian market, bringing the prestige and allure of a world-class luxury brand,"&nbsp;Altus founder and chief executive David Young said.

"Altus Property Group is proud of its track record in delivering landmark developments across Australia, and our expertise ensures this project will be an outstanding success."

Trump Hotel heads for the Gold Coast to become Australia's tallest building

More than a century after the Corrimal Coke Works first opened in 1912, the industrial landmark that helped shape the suburb is being reinterpreted as a walkable residential neighbourhood, with Stage One of <a href="https://www.apartments.com.au/new-apartments/the-works-stage-one-27-railway-street-corrimal-nsw-2518">The Works</a> now underway at 27 Railway Street.

For 102 years, the site was central to <a href="https://www.apartments.com.au/developments/corrimal-nsw-2518">Corrimal</a>’s economic and social identity before operations ceased in 2014. Rather than erasing that legacy, developer Legacy Property has embedded it into the masterplan, retaining and reinterpreting elements such as the iconic 1912 brick chimney and sections of the original C1 Coke Oven Battery, alongside the adaptive reuse of the former powerhouse building.

Stage One will introduce 181 apartments across low-rise buildings, offering predominantly two and three-bedroom residences with completion targeted for mid-2027. The scale and configuration reflect a deliberate focus on owner-occupiers, targeting those seeking a lower-maintenance home in a prime location within the northern suburbs of Wollongong.

[smartcode_project:default project_id=143415 project_image_fid=359833]

Apartments have been designed to maximise natural light and cross-ventilation, with floor-to-ceiling glazing extending living areas onto generous balconies. Engineered timber flooring, induction cooktops and 900mm ovens in larger residences support everyday functionality, while two interior palettes allow buyers to tailor finishes to their preferences. The material selection draws on a restrained coastal language, intended to connect homes to their surroundings rather than compete with them.

The Works forms part of a broader 18-hectare masterplan that will ultimately deliver around 550 dwellings, new parks, and a heritage precinct celebrating the site’s past. More than seven hectares are dedicated to open space, including Southern Park and a Village Green with community gardens and recreation areas. The creek corridor is being rehabilitated with 150,000 native plantings, restoring biodiversity to the site and softening landscape.

[smartcode_project:default project_id=143415 project_image_fid=359841]

Positioned adjacent to Corrimal Station and within walking distance of Corrimal Town Centre, the precinct places daily essentials, rail connections and local retail within easy reach. Wollongong CBD, including the hospital, university and entertainment venues, sits approximately 6.5 kilometres to the south.

For buyers more familiar with North Wollongong, Corrimal offers a different proposition: a well-established coastal suburb framed by beaches to the east and the escarpment to the west, with a strong sense of local identity shaped in part by the former Coke Works. The Works seeks to reinforce that identity by creating a connected, walkable neighbourhood between coast and escarpment, rather than a standalone apartment complex.

Sustainability underpins the development approach. The Works is targeting Wollongong’s first 5-Star Green Star-rated community, with water-sensitive urban design, recycled materials and energy-efficient buildings integrated across the masterplan. For residents, these measures provide not only environmental benefits but also reduced operational costs and future resilience.

[smartcode_project:default project_id=143415 project_image_fid=359842]

With construction commenced and display materials available to view, prospective buyers can now engage more directly with the project’s vision, reviewing floorplans, material selections and the broader masterplan in detail. For many local homeowners weighing a move, the opportunity to experience how heritage, landscape and contemporary design intersect may help bridge the gap between familiarity and the next chapter.

As Stage One progresses toward its mid-2027 completion, The Works represents a significant chapter in Corrimal’s evolution, transforming a site that once powered local industry into a walkable residential precinct designed for its next generation of residents.

Legacy Property’s The Works reimagines Corrimal’s century-old Coke Works

When it comes to developing in Melb​ourne's Bayside region, <a href="https://www.apartments.com.au/developers/lowe-living">Lowe Living</a> knows exactly what buyers want.

With a longstanding presence in the area and a string of sell-out projects, Lowe Living consistently delivers developments that are as sought-after as their predecessors.

Their latest instalment is in <a href="https://www.apartments.com.au/developments/hampton-vic-3188">Hampton</a><a href="https://www.apartments.com.au/developments/hampton-east-vic-3188">&nbsp;East,</a> the same postcode where they have previously delivered Hampton Hill and Oceano. The developer-builder recently commenced construction on its newest project,&nbsp;<a href="https://www.apartments.com.au/new-apartments/marella-hampton-31-35-alicia-street-hampton-east-vic-3188">Marella</a>, a collection of 32 apartments just five minutes from the beach.

Site acquisition is paramount to success. Lowe Living rarely brings a building to market that isn’t within walking distance of essential amenities, whether it be the beach, a prominent retail strip, or a train station. Marella is no exception, located at its Alicia Street address, less than a kilometre from the retail heart of Hampton Street and Hampton Station.

[smartcode_project:default project_id=146197 project_image_fid=358495]

Equally important to Lowe Living is the architecture.

For Marella, they appointed <a href="https://www.apartments.com.au/architects/cera-stribley-architects">Cera Stribley</a>, who explains that the architectural vision was to create a contemporary reinterpretation of the Californian bungalow, a style that’s iconic to Hampton’s heritage.

"By borrowing, abstracting, and reinterpreting elements of this quintessential style, such as strong datum lines, articulated columns, exposed structures, and roof tiles, our design strikes a balance between modernity and familiarity," says Cera Stribley.

"This approach ensures that the development is not only visually appealing but also contextually sensitive, resonating with Hampton's existing architectural landscape."

[smartcode_project:default project_id=146197 project_image_fid=358499]

The building features terracotta brick, soft cream masonry, and exposed metal detailing, giving it a tactile presence that is intended to weather gently over time.

Internally, the focus on lasting quality continues, with two and three-bedroom residences anchored by sculptural stone kitchen islands, natural light, and clearly defined transitions between living, dining, and outdoor spaces.

The layouts have been carefully designed. Open-plan zones extend to private balconies, with light-filled interiors and generous kitchen proportions, supported by Miele wall ovens, induction cooktops, and integrated fridge-freezers. These are not small apartments rebranded as luxury; they have been designed at scale, with ample storage, hotel-style entry access, and secure basement parking provided as standard.

[smartcode_project:default project_id=146197 project_image_fid=358492]

At the uppermost level, Marella’s Signature Collection penthouses offer city or bay views, large entertaining terraces (some with outdoor spas), and elevated finishes, including fully wrapped stone kitchen benches and a Liebherr wine fridge.

Flexible room arrangements allow for a fourth bedroom or secondary living space, sought-after by both empty nesters who want the space when family visits and families with older children.

[smartcode_project:default project_id=146197 project_image_fid=358498]

A residents’ lounge on the ground floor reinforces the project’s small-community feel. With a fireplace, private dining area, and adjoining terrace, it’s one of several shared spaces that balance amenity with privacy and scale.

Construction has commenced, with completion expected in early 2027.

GUEST OBSERVATION
You may mock the national anthem by singing “Our land abounds in nature strips” but what you might not know is how true that is.
In Melbourne, for example, <a href="https://www.sciencedirect.com/science/article/pii/S1618866719300718" target="_blank">more than a third of all public green space is nature strips</a>. (That figure includes roundabouts, medians and other green bits of the street.)
That’s a remarkable amount. The nature strip is everywhere. A million small patches combine into a giant park spanning the city, making it a significant player in our urban ecosystems.
A second remarkable thing is that the nature strip is <a href="https://apo.org.au/sites/default/files/resource-files/2007/11/apo-nid60258-1105966.pdf" target="_blank">public land that private citizens are required by law to maintain</a>. Councils manage the trees, but we residents mow the lawn.
What are the rules on nature strips?
<a href="https://images.theconversation.com/files/296146/original/file-20191009-3872-1i673y4.JPG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/296146/original/file-20191009-3872-1i673y4.JPG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt=""></a>
Succulents, Agapanthus and Gazanias are the most common plantings on nature strips. Adrian Marshall CC BY 4.0, Author provided
Many residents go further and plant a street tree or some garden plants – succulents, Agapanthus and Gazanias are the most common. But the chances are that, whatever the garden on the nature strip, it’s against the rules.
The rules on nature strips vary from council to council. Some councils don’t allow any plantings. Others restrict plantings by height or allow only plants indigenous to the local area. In some areas, nature strips can only be planted to prevent erosion on steep slopes.
Some councils disallow food plants, for fear of historic lead contamination from leaded petrol. Others insist on no plants within a metre of the kerb and two metres of the footpath.
These bylaws are inconsistent and illogical. For instance, councils that insist on indigenous species nevertheless plant exotic street trees. Councils that say plants must be less than 30cm high to ensure they don’t block drivers’ sight lines still allow vehicles to park on the street, blocking sight lines.
Bylaws deny us many benefits
To have council bylaws restrict or disallow gardening in the nature strip flies in the face of common sense. Street greenery, whether it's trees, shrubs or lawn, provides many benefits. The science is in on this.
Urban wildlife uses street greenery for habitat and food and as green corridors for movement.
Even for those who mow, the lawns of nature strips are not just turf grass. They are home to over 150 species of plants, based on my yet-to-be-published survey data for nearly 50 neighbourhoods, confirming <a href="https://link.springer.com/article/10.1007/s11252-009-0098-7" target="_blank">earlier studies</a>. Many of these, like the clovers, provide important resources for pollinators.
One <a href="https://www.propertyobserver.com.au/https://www.nrs.fs.fed.us/pubs/55816" target="_blank">US study</a> showed that changing from a weekly mow to every three weeks increased the number of flowers in a lawn by 250%. Less mowing is good news for bees and butterflies.
An unpublished recent survey by the author and colleagues found gardening in the nature strip adds native plants to the streetscape, increases biodiversity and add structural complexity (more layers of plants, more types of stuff), which is important for many species.
<a href="https://images.theconversation.com/files/296397/original/file-20191010-188823-3m94cd.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/296397/original/file-20191010-188823-3m94cd.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
The greater the diversity of plantings, the greater the benefits a nature strip can provide. <a href="https://www.flickr.com/photos/tedxmelbourne/9642464172/in/photolist-hj8dyc-skaU1u-dREut-eJsU1F-ffLmZK-indYV3-cLiW2J-vB2sc-7NsaK4-4VkF3d-yGjbRF-beH7sn-6Y5uUZ-rxC4mN-6LgaCq-8uZkP8-fFMrYB-fFMzz6-959BCc-fFMqN6-9XyM3R-8uZkQZ-fG59Eh-fG55kj-MdakbU-zKkV6-9A3mjp-2hgzR2Y-2gLLfma-2gLM1dK-2gjDcaq-fG56q1-V4CxJS-2EepMw-AJYA3h-8PLEFM-2Nnv4q-3HCckP-8LfDb6-F9XHNG-fG5dib-9hzViT-d5L2G-fG57A5-7tQdTT-vh8B5S-2d9eEDd-2gtBYEp-fFMxhv-6tVDoj" target="_blank">TEDxMelbourne/Flickr</a>, <a href="http://creativecommons.org/licenses/by-nc-nd/4.0/" target="_blank">CC BY-NC-ND</a>

It <a href="https://www.propertyobserver.com.au/https://www.ncbi.nlm.nih.gov/pubmed/26828172" target="_blank">cools streets</a> and <a href="https://www.sciencedirect.com/science/article/pii/S0169204614002503" target="_blank">helps counter the urban heat island effect</a>. It also <a href="https://www.sciencedirect.com/science/article/abs/pii/S0277953613003742" target="_blank">promotes a sense of community</a>, <a href="https://www.sciencedirect.com/science/article/pii/S2214140518303281" target="_blank">encourages walking</a> and lowers the incidence of <a href="https://www.sciencedirect.com/science/article/pii/S2214140518303281" target="_blank">heart disease</a>, <a href="https://www.propertyobserver.com.au/https://jamanetwork.com/journals/jama/fullarticle/2524191" target="_blank">diabetes</a>, <a href="https://theconversation.com/children-living-in-green-neighbourhoods-are-less-likely-to-develop-asthma-96190" target="_blank">asthma</a> and <a href="https://www.sciencedirect.com/science/article/pii/S0169204614002941" target="_blank">depression</a>.
But councils tend to be risk-averse. They worry they will be sued if someone trips on groundcover or stubs their toe on an out-of-place garden gnome.
Fortunately, this risk aversion isn’t universal. For instance, the <a href="https://www.vincent.wa.gov.au/residents/environment/environmental-sustainability/news-events/adopt-a-verge.aspx" target="_blank">City of Vincent</a> in Western Australia is so keen for residents to convert lawn to waterwise plantings that it will remove turf and provide native plants.
But, as climate change looms, stubbed toes are not the main risk we should be worrying about. Rather, we must urgently remake our cities and our culture for sustainability and resilience.
Gardening becomes a neighbourly act
One of the great things about gardening in the nature strip is that people are <a href="https://www.sciencedirect.com/science/article/pii/S1618866719302535" target="_blank">more likely to do it if their neighbours do it</a>. It’s contagious, a positive-feedback loop creating a greener street.
Our recent survey found residents who garden in the nature strip have a greater <a href="http://www.communityscience.com/news-detail.php?news=114" target="_blank">sense of community</a> than those who don’t.
<a href="https://images.theconversation.com/files/296997/original/file-20191015-98653-wopjbq.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/296997/original/file-20191015-98653-wopjbq.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
A well-designed street garden, fully covering the nature strip, allowing pedestrian access to cars and using indigenous plants. Adrian Marshall CC BY 4.0, Author provided
Interestingly, the benefits nature strips provide are <a href="https://www.sciencedirect.com/science/article/pii/S1618866719302535" target="_blank">not equally distributed across the city</a>. For instance, newer neighbourhoods have more nature strip than older neighbourhoods (though their trees are younger). People garden the nature strip more on minor roads than major roads, and in more socially advantaged neighbourhoods.
Almost a <a href="https://www.sciencedirect.com/science/article/pii/S1618866719302535" target="_blank">quarter of residential properties</a> in Melbourne have some sort of nature strip gardening. If councils were to encourage this activity we might achieve more street greening with little cost to our cash-strapped councils. Such encouragement would also free many residents of their sense of frustration at being required to maintain the nature strip but forbidden to do anything more than mow.
Given that more than a third of our public green space is nature strip, the many small actions of residents can add up to substantial positive change.<img src="https://counter.theconversation.com/content/124781/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1">

Our land abounds in nature strips – surely we can do more than mow a third of urban green space

<html><body>
GUEST OBSERVATION
Greening our cities has become one of the great <a href="https://newclimateeconomy.report/2018/wp-content/uploads/sites/6/2018/09/NCE_2018_FULL-REPORT.pdf" target="_blank">global imperatives</a> of the 21st century including to tackle climate change. And Australia’s sprawling car-based cities are gradually changing to embrace green or living infrastructure.
Green cities bring together elements of architectural design and urban planning, often combining plants and built infrastructure to meet the needs of humans, such as our <a href="https://en.wikipedia.org/wiki/Biophilia_hypothesis" target="_blank">love of nature</a>.
Trees, plants, waterways and wetlands can deliver climate conditioning, cooling cities by reducing the urban heat island effect. They also absorb carbon dioxide, filter wastewater and create habitats.
Living elements can be incorporated with built infrastructure at a range of scales, from individual buildings with green walls and roofs, through to citywide strategies. And there are a <a href="http://www.curf.com.au/files/view/?id=633" target="_blank">suite of strategies</a> to guide more widespread integration of biological elements and ecological processes in cities.
In recent months, we <a href="https://mainstreaminggreeninfrastructure.com/reports/Barbara%20Norman%20mainstreaming%20GI%20in%20Australia.pdf" target="_blank">profiled Australian examples of living infrastructure</a> that show some of Australia’s approaches to developing green infrastructure, from greening Melbourne’s laneways to Canberra’s urban forest. These cities are already redesigning their water systems and implementing urban forest strategies to create green belts and protect and restore waterways.
Melbourne and Canberra provide some useful examples of the green cities movement, but to make it mainstream, these techniques need to be adopted widely through policies supporting more holistic and better integrated urban planning.
Why we need urban forests
Percival Alfred Yeoman was one of the first Australian pioneers of urban forestry. In 1971, <a href="https://www.propertyobserver.com.au/https://trove.nla.gov.au/work/8870297?q&amp;versionId=12235056" target="_blank">he articulated</a> a clear vision for enhancing cities with trees.
Local governments in Adelaide, Brisbane, Melbourne and Sydney, are implementing his ideas, committing to <a href="https://202020vision.com.au/about-the-vision/" target="_blank">ambitious increases in urban canopy cover</a>. Their targets range from 25% to 40%.
This <a href="https://202020vision.com.au/the-network/" target="_blank">revived interest in urban forestry</a> comes from its well documented potential for accelerating the transition to more climate adaptive cities.
The social, environmental and economic benefits of urban trees, or “ecosystem services”, are becoming better recognised, including for their recreational and cultural values.
<h2>Melbourne and Canberra are leading Australia’s green cities movement</h2>
<h3>Melbourne</h3>
Melbourne has a rich legacy of urban parks and green belts thanks to planning decisions made in the city’s early years.
These parks underpin a new wave of urban greening, with projects that aim to deliver action on climate change, biodiversity and the health and well-being of communities.
The Melbourne green infrastructure <a href="https://www.melbourne.vic.gov.au/community/greening-the-city/green-infrastructure/Pages/green-infrastructure.aspx" target="_blank">plan</a> includes: 
<ul>
<li>a “<a href="http://www.growinggreenguide.org/" target="_blank">growing green guide</a>” that provides practical advice to community and business groups on planning, design and maintenance of green infrastructure </li>
<li>the <a href="http://www.melbourne.vic.gov.au/community/%20greening-the-city/green-infrastructure/Pages/greeninglaneways.%20aspx">greening laneways strategy</a>, which builds on the commercial revitalisation of Melbourne’s laneways over three decades. Laneways with greening potential were mapped and demonstration project developed to display techniques for making them more vibrant green spaces for business, tourists and locals to enjoy</li>

<h3>Canberra</h3>
Canberra is often described as “a city within a landscape” and the “bush capital”. But its higher altitude, hot dry summers and cold winters bring a set of challenges for green infrastructure.
With more than 800,000 planted trees, Canberra is an urban forest. But these trees require special care and attention given they are ageing and suffering from a hotter, drier climate.
Wildfire also represents a significant risk where urban and rural areas connect. This means Canberra needs urban forests that will cool the city in warmer months without also escalating wildfire risks.
The <a href="/news">ACT Government</a> has committed to action on climate change, legislating targets for 100% renewable electricity by 2020 and carbon neutrality (no net carbon emissions) by 2045.
Integrated approach needed to expand green cities
Greening cities requires a holistic approach – for instance, not leaving the health of waterways entirely to water engineers.
Greening cities is more than just a <a href="https://www.academia.edu/38053856/The_city_as_nature_and_the_nature_of_the_city_-_climate_adaptation_using_living_infrastructure_governance_and_integration_challenges" target="_blank">technical challenge</a>. Transforming the form and functions of urban systems, through urban forests and other living infrastructure, <a href="http://www.curf.com.au/files/view/?id=633" target="_blank">requires</a> greater leadership and political commitment, integrated planning and community participation, and long-term thinking.
An integrated approach to greening cities involves mapping diverse opportunities and mobilising support for change in the community. As an example, urban storm water can be a productive resource when used in constructed wetlands or to irrigate urban forests.
And often urban drainage lines and wastelands can be transformed into green spaces, but it’s worth recognising there is intense competition for space for housing.
But for more widespread adoption of integration, institutional support within local governments and metropolitan water and planning agencies is needed.
So to scale up living infrastructure in our urban landscapes, we must learn from local success stories, conduct more research, and better understand how to deal with climate adaptation and mitigation challenges.

For green cities to become mainstream, we need to learn from local success stories and scale up

EXPERT OBSERVER
Urgent and radical change in urban transport policies and practices will benefit the planet and future generations.
The UN Intergovernmental Panel on Climate Change recently warned that <a href="https://www.theguardian.com/environment/2018/oct/08/how-the-un-climate-panel-ipcc-got-to-15c-threshold-timeline" target="_blank">global warming could reach 1.5℃ as early as 2030</a>. The landmark <a href="http://www.ipcc.ch/report/sr15/">report</a> by leading scientists urged nations to do more to avert an impending crisis.
<a href="https://www.vox.com/2018/10/8/17948832/climate-change-global-warming-un-ipcc-report" target="_blank">We have 12 years</a>, the report said, to contain greenhouse gas emissions. This includes serious efforts to reduce transport emissions. 
In Australia, transport is the <a href="https://www.climatecouncil.org.au/resources/transport-fact-sheet/" target="_blank">third-largest source of greenhouse gases</a>, accounting for around <a href="/news">17% of emissions</a>. Passenger cars account for <a href="https://www.climatecouncil.org.au/resources/transport-fact-sheet/" target="_blank">around half of our transport emissions</a>.
The transport sector is also one of the strongest factors in emissions growth in Australia. Emissions from transport have <a href="/news">increased nearly 60% since 1990</a> – <a href="https://www.climatecouncil.org.au/resources/transport-fact-sheet/" target="_blank">more than any other sector</a>. Australia is ranked <a href="https://aceee.org/research-report/i1801" target="_blank">20th out of 25 of the largest energy-using countries for transport energy efficiency</a>.
Cities around the world have many opportunities to reduce emissions. But this requires renewed thinking and real commitment to change.
Our planet can’t survive our old transport habits
Past (and still current) practices in <a href="https://theconversation.com/australian-infrastructure-plan-has-some-way-to-go-to-give-our-cities-what-they-need-54954" target="_blank">urban and transport planning</a> are fundamental causes of the transport problems we face today.
Over the past half-century, cities worldwide have <a href="https://theconversation.com/density-sprawl-growth-how-australian-cities-have-changed-in-the-last-30-years-65870" target="_blank">grown rapidly, leading to urban sprawl</a>. The result was high demand for motorised transport and, in turn, increased emissions.
The traffic gridlock on roads and motorways was the catalyst for most transport policy responses during that period. The solution prescribed for most cities was to <a href="https://theconversation.com/stuck-in-traffic-we-need-a-smarter-approach-to-congestion-than-building-more-roads-84774" target="_blank">build out of congestion by providing more infrastructure for private vehicles</a>. Limited attention was given to <a href="https://theconversation.com/on-the-road-research-can-improve-transport-across-australia-43643" target="_blank">managing travel demand</a> or improving other modes of transport.
Equating mobility with building more roads nurtured a tendency towards increased motorisation, reinforcing an ever-increasing inclination to expand the road network. The result was a range of unintended adverse <a href="http://www.oecd.org/economy/rethinking-urban-sprawl-9789264189881-en.htm" target="_blank">environmental, social and economic consequences</a>. Most of these are rooted in the high priority given to private vehicles.
What are the opportunities to change?
The various strategies to move our cities in the right direction can be grouped into four broad categories: avoid, shift, share, and improve. Major policy, behaviour and technology changes are required to make these strategies work.
Avoid strategies aim to slow the growth of travel. They include initiatives to reduce trip lengths, such as <a href="https://theconversation.com/higher-density-and-diversity-apartments-are-australia-at-its-most-multicultural-97176" target="_blank">high-density</a> and <a href="https://theconversation.com/a-place-to-live-work-and-play-why-mixed-use-developments-are-making-a-comeback-73142" target="_blank">mixed land use developments</a>. Other options decrease private vehicle travel – for example, through car/ride sharing and <a href="https://www.gizmodo.com.au/2015/12/how-to-fix-traffic-congestion-in-australia/" target="_blank">congestion pricing</a>. And <a href="https://theconversation.com/go-forth-and-telework-but-will-it-work-for-you-10682" target="_blank">teleworking</a> and e-commerce help people avoid private car trips altogether.
Shanghai’s Hongqiao transport hub is a unique example of an <a href="https://uic.org/cdrom/2013/nextstation/doc/proceedings/3Ajianping.pdf" target="_blank">integrated air, rail and mixed land use development</a>. It combines Hongqiao’s airport, metro subway lines, and regional high-speed rail. A low-carbon residential and commercial <a href="https://www.usgbc.org/articles/building-shanghai-tomorrow-hongqiao-cbds-low-carbon-transportation-hub">precinct</a> surrounds the hub.
<a href="https://images.theconversation.com/files/246775/original/file-20181122-161609-x8oxhj.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/246775/original/file-20181122-161609-x8oxhj.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>

Shift strategies encourage travellers to switch from private vehicles to public transport, walking and cycling. This includes improving bus routes and service frequency.
<a href="https://theconversation.com/stuck-in-traffic-we-need-a-smarter-approach-to-congestion-than-building-more-roads-84774" target="_blank">Pricing strategies</a> that discourage private vehicles and encourage other modes of transport <a href="https://www.ted.com/talks/jonas_eliasson_how_to_solve_traffic_jams" target="_blank">can also be effective</a>. Policies that include <a href="https://www.theguardian.com/money/2018/jul/02/norway-electric-cars-subsidies-fossil-fuel" target="_blank">incentives</a> that make electric vehicles more affordable have been shown to encourage the shift.
Norway is an undisputed world leader in electric vehicle uptake. <a href="https://www.theguardian.com/environment/2017/dec/25/norway-leads-way-electric-cars-green-taxation-shift" target="_blank">Nearly a third of all new cars sold in 2017 were a plug-in model</a>. The electric vehicle market share was expected to be as much as 40% within a year.
An electric vehicle charging station in the Norwegian capital Oslo. <a href="https://www.shutterstock.com/image-photo/electric-car-charging-station-oslo-eco-670494520?irgwc=1&amp;utm_medium=Affiliate&amp;utm_campaign=TinEye&amp;utm_source=77643&amp;utm_term="> </a>
Share strategies affect car ownership. New sharing economy businesses are already moving people, goods and services. Shared mobility, rather than car ownership, is providing city dwellers with a real alternative.
This trend is likely to continue and will pose significant challenges to car ownership models.
Uber claims that its <a href="https://www.uber.com/en-IN/blog/mumbai/onestepforward-with-uberpool/" target="_blank">carpooling service in Mumbai</a> saved 936,000 litres of fuel and reduced greenhouse gas emissions by 2,662 metric tonnes within one year. It also reports that <a href="http://www.cityam.com/242760/uber-reveals-london-ride-sharing-figures-for-uberpool" target="_blank">UberPool in London</a> achieved a reduction of more than 1.1 million driving kilometres in just six months.
<img src="https://images.theconversation.com/files/244778/original/file-20181109-35554-ym7dj5.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="">
UberPool is available in inner Melbourne suburbs. Trip must begin and end in this area.
Improve strategies promote the use of technologies to optimise performance of transport modes and <a href="https://theconversation.com/intelligent-infrastructure-when-roads-and-vehicles-talk-to-each-other-7865" target="_blank">intelligent infrastructure</a>. These include <a href="https://www.weforum.org/agenda/2015/03/why-our-cities-need-smart-transport/" target="_blank">intelligent transport systems</a>, urban information technologies and emerging solutions such as <a href="https://www.itf-oecd.org/files/urban-mobility-system-upgrade" target="_blank">autonomous mobility</a>.
Our <a href="https://www.tandfonline.com/doi/abs/10.1080/23249935.2018.1528485?journalCode=ttra21" target="_blank">research</a> shows that sharing 80% of autonomous vehicles will reduce net emissions by up to 20%. The benefits increase with wider adoption of autonomous shared electric vehicles.
Autonomous vehicles can offer first- and last-kilometre solutions, especially in outer suburbs with limited public transport services. <a href="https://www.shutterstock.com/image-photo/iot-smart-automotive-driverless-car-artificial-794528215?irgwc=1&amp;utm_medium=Affiliate&amp;utm_campaign=TinEye&amp;utm_source=77643&amp;utm_term="> </a>
The urgency and benefits of steering our cities towards a path of low-carbon mobility are unmistakable. This was recognised in the past but progress has been slow. Today, the changing context for how we build future cities – smart, healthy and low-carbon – presents new opportunities.
If well planned and implemented, these four interventions will collectively achieve transport emission reduction targets. They will also improve access to the jobs and opportunities that are preconditions for sound economic development in cities around the world.<img src="https://counter.theconversation.com/content/106076/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1">

Four ways our cities can cut transport emissions in a hurry

<html><body>
Population growth has seen skylines creep ever higher and entire cities rise from ocean depths. The latest “ocean city” is the Chinese-developed <a href="https://cgpvforestcity.wordpress.com/category/press-release/" target="_blank">Forest City project</a>. By 2045, four artificial islands in Malaysia will cover 14km² of ocean (an area larger than 10,000 Olympic swimming pools), and support 700,000 residents.
Often overlooked, however, is the damage that artificial islands can cause to vital seafloor ecosystems. But it doesn’t have to be this way. If proper planning and science are integrated, we can develop the design strategies that will help build the “blue-green” ocean cities of tomorrow.
Colonising the ocean frontier
Ever growing numbers of human-made structures are <a href="https://theconversation.com/concrete-coastlines-its-time-to-tackle-our-marine-urban-sprawl-38175" target="_blank">occupying our oceans</a>. Cities built on artificial islands in the ocean are providing a solution for urban planners trying to manage the population squeeze.
And yet, so-called “<a href="https://www.propertyobserver.com.au/https://esajournals.onlinelibrary.wiley.com/doi/abs/10.1890/110246?af=R" target="_blank">ocean sprawl</a>” dates as far back as <a href="http://www1.frm.utn.edu.ar/laboratorio_hidraulica/Biblioteca_Virtual/Coastal%20Engineering%20Manual%20-%20Part%20I/Part_I-Chap_3entire.pdf" target="_blank">Ancient Egypt</a>. Over the past few centuries, artificial islands have been built through land reclamation. Land reclamation is the process of creating new land from existing water bodies.

The Netherlands, for instance, has been draining lakes and expanding its coastline to <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/ird.340" target="_blank">fight the advance of the sea</a> since the 1500s. The Dutch actually built one of the first and largest artificial islands, which is <a href="https://www.tourism-review.com/travel-tourism-magazine-flevoland-worlds-largest-artificial-island--article2372" target="_blank">now home to some 400,000 people</a>. Japan’s third-busiest airport, the <a href="https://www.kansai-airport.or.jp/en/" target="_blank">Kansai International Airport</a>, was built on an artificial island in 1994. China has also been building into the oceans, reclaiming <a href="https://www.sciencedirect.com/science/article/pii/S0964569114000696" target="_blank">more than 13,000km² of seafloor</a> and an estimated <a href="https://www.propertyobserver.com.au/https://esajournals.onlinelibrary.wiley.com/doi/epdf/10.1890/130260" target="_blank">65% of tidal habitat</a> since the 1950s.

Using Google maps, we were able to identify more than 450 artificial islands around the world, including the famous Palm Islands of Dubai. These are often celebrated as <a href="https://www.iveyengineering.com/modern-engineering-marvels/" target="_blank">engineering marvels</a>, but at what cost to the marine environment?
<h2>We can’t ignore what lies beneath</h2>
Marine habitats have always been essential for human life in coastal regions. They provide food, building and crafting materials, and less-known services such as <a href="https://esajournals.onlinelibrary.wiley.com/doi/full/10.1890/10-1510.1" target="_blank">coastal protection, nutrient cycling and pollution filtration</a>.

One of the World Map islands in Dubai, United Arab Emirates. Shutterstock
The creation of artificial islands causes <a href="https://www.sciencedirect.com/science/article/pii/S0022098117300606" target="_blank">large changes to the seabed</a> by permanently smothering local habitats. In many parts of the world, existing habitats provide the foundation for artificial island construction. For instance, artificial islands in the tropics are often built directly on top of coral reefs. This leads to considerable destruction of already threatened ecosystems.
Land reclamation also impacts nearby habitats that are particularly sensitive to murky waters, such as coral reefs and seagrass beds. In Singapore, land reclamation is associated with <a href="https://www.researchgate.net/profile/L_Chou/publication/285088156_Response_of_Singapore_reefs_to_land_reclamation/links/569c63b008aea1476954792e.pdf" target="_blank">coral reef decline due to sedimentation and resulting light reductions</a>. Singapore has lost <a href="https://www.sciencedirect.com/science/article/pii/S096456911400355X" target="_blank">nearly 45% of the country’s intertidal reef flats and almost 40% of intertidal mudflats</a>.
When the ecological, economic, and social value of marine habitats are considered, artificial islands and ocean sprawl seem to be indulgences that we cannot afford. The effects would be akin to the suburban sprawl of the 20th century. To avoid this cost, we need to address the complexities of the underwater world in urban planning and development.
<h2>“Blue urbanism”</h2>
In his book <a href="http://blueurbanism.org/blue-urbanism-cities-and-oceans-together/" target="_blank">Blue Urbanism</a>, Timothy Beatley calls for urban planners to consider and value ocean ecosystems. He argues that we need to recognise the <a href="http://bigthink.com/articles/need-a-nature-break-why-blue-is-the-new-green-for-stress-relief">psychological value of human connections to blue space</a>, and extend green practices on land into marine environments. While some artificial island developments such as the Forest City project are touted as “eco-cities”, more could be done both to minimise impacts below the waterline and integrate underwater environments into city life.
Why not combine a “Forest City” with the principles of a “<a href="https://theconversation.com/chinas-sponge-cities-aim-to-re-use-70-of-rainwater-heres-how-83327">Sponge City</a>”? While native plantings in a forest city could help to reduce air pollution, sponge cities seek to “absorb” and reuse rainwater, thus reducing pollution entering the oceans through <a href="https://theconversation.com/massive-storms-are-pumping-pollution-into-our-oceans-time-to-clean-up-our-cities-60551">stormwater runoff</a>. Around artificial islands, developers could also embrace the <a href="https://www.scapestudio.com/projects/oyster-tecture/" target="_blank">water filtration powerhouse</a> of the oceans: active oyster reefs.
The location of future constructions should also be carefully evaluated to ensure the preservation of important marine habitats. Artificial islands have the potential to create <a href="https://theconversation.com/our-oceans-are-out-of-balance-can-we-learn-some-tips-from-feng-shui-64975" target="_blank">fragmented seascapes</a>, but with careful spatial planning and smart designs, they could create corridors for some <a href="https://mashable.com/2015/06/01/global-warming-huge-oceans-shift/#66PBDFJxyuq4" target="_blank">climate migrants</a> or those threatened species most at risk from habitat loss.
<img src="https://counter.theconversation.com/content/93843/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1">Designs based on ecological principles can reduce the impacts of artificial islands on natural habitats. However, applications of “blue-green” infrastructure remain largely untested at large scales. New designs, building strategies and spatial planning that integrate seascapes and landscapes are an opportunity for both “smarter” cities and experimentation for the development of successful blue-green technologies.

Green engineering needed above and below water in future 'ocean cities'

<html><body>
<img src="https://counter.theconversation.edu.au/content/57114/count.gif" alt="The Conversation" width="1" height="1">
GUEST OBSERVER
In the 1953 short story The Man Who Planted Trees, a lone shepherd plants thousands of trees, transforming a desolate valley into a vibrant forest with pleasant villages and unspoiled wilderness. The moral of this story is a simple one: that perseverance and planting trees can make places more desirable to live.
Across the United States, the US Forest Service is proving this, neighbourhood by neighbourhood.
Within some neighbourhoods, scientists are documenting a connection between trees and a specific social improvement: a reduction in crime. These studies combine modern mapping technology with spatial and economic statistics to compare crime levels between similar urban neighbourhoods in the same city.
This research is becoming increasingly widespread and sophisticated. According to Kathleen Wolf, a research social scientist with the University of Washington and the US Forest Service, this is “part of a movement to understand the role of nature in public health”. Wolf observes:
"Now that we’re in the era of Big Data, we’re seeing an acceleration of crime-related research in a wide variety of disciplines and fields. We’re also incorporating data on things like disparities of green in urban communities."
Not only do healthy, well-maintained trees provide shade and benefit the ecosystem, they can have a social meaning: that people in that neighbourhood look out for each other.
<h2>Progress in Baltimore</h2>
One of the places we are conducting this type of research is Baltimore. One of the oldest cities in US, Baltimore has more than 600,000 residents. It is known for its rich historical heritage, a picturesque inner harbour, crab cakes … and for having some of the worst crime and poverty levels in the nation.
According to recent estimates, 25 percent of Baltimore residents and 37 percent of Baltimore children live in poverty.
Faced with one of the highest homicide rates in the country, the city implemented a youth curfew law in 2014 to keep unaccompanied children off the streets at night.
Baltimore also has an extensive team of urban research scientists, affiliated with both the US Forest Service Baltimore Field Station and the Baltimore Ecosystem Study, and a proactive non-profit organisation, The Parks &amp; People Foundation. These entities are working together to demonstrate a connection between adding trees and reducing crime in under-served neighbourhoods.
We worked in a research collaboration to look at the relationship between urban tree cover and rates of robbery, burglary, theft and shooting in under-served neighbourhoods in Baltimore. After controlling for income, population density, block-scale tree canopy and housing type, we found that a 10% increase in tree canopy corresponded to a roughly 12 percent decrease in crime.
According to Valerie Rupp, director of community greening for The Parks &amp; People Foundation in Baltimore, people are taking back their neighbourhoods. “While crime still exists, there’s been a shift to more minor, less violent crimes,” she says.
<h2>Pride and goodwill in Philadelphia</h2>
Less than 150 kilometres northwest of Baltimore is the city of Philadelphia, another historic metropolis. With a population of more than 1.5 million, Philadelphia also has its share of big-city problems.
Although Philadelphia’s homicide rate is lower than Baltimore’s, the city has one of the highest homicide rates of the country’s ten most populous cities.
The US Forest Service Philadelphia Field Station is working with city groups such as the Parks and Recreation Department and the Philadelphia Water Department to establish the “triple bottom line”, meaning improvements in three broad areas of impact – environmental, social and economic.
In terms of crime reduction, our studies have found that “green” stormwater infrastructure improvements resulted in significant reductions in narcotics possession and theft. According to Philadelphia police detective Hugh Davis, one can feel neighbourhoods changing and becoming safer over time. Davis says:
"It often starts out as a grant program to make landscape improvements, and then residents start to take ownership. It improves neighbourhood pride and goodwill toward the city."
<h2>Developing ‘green courage’ in the inner city</h2>
The theory behind urban greening and reduced crime levels is that when under-served neighbourhoods are made more pleasant, it can result in a healthier sense of community. In turn, it makes those neighbourhoods less hospitable to criminal activity.
In places like Baltimore and Philadelphia, city departments are working with communities to give people what some urban sociologists call “green courage”. This occurs when residents become more willing to work together after seeing improvements in their neighbourhood.
At the end of the day, urban greening is not simply about planting trees. It’s about people working together to make neighbourhoods better places to live.
We are working alongside these efforts, helping to document and provide a scientific basis for the work to spread and continue. For those of us who are working toward these goals, we sometimes wonder: are we planting trees to organise people or are we organising people to plant trees?
The best answer is probably “yes” to both.
