The cost of green infrastructure can be influenced by factors such as the type of project, location, and integration with planned infrastructure improvements.

Integrating green projects with planned infrastructure improvements, such as road reconstruction or roof replacements, can lead to cost savings of 30% to 60% over the lifetime of the project due to the multiple benefits that green infrastructure offers back to the built environment. 

It is important to note that the cost of green infrastructure is not solely determined by the initial construction costs but also includes life cycle costs, including planning, design, installation, operation and maintenance, and replacement. 

The cost-analysis of green infrastructure should be analyzed in conjunction with its performance and the multiple benefits it provides, including environmental, economic, and community benefits.

How do Cities Fund Green Infrastructure Projects?

20220421 153027 green infrastructure expensive Citygreen

Cities typically fund green infrastructure projects through a variety of mechanisms, including public and private sources. Some of the common funding sources and mechanisms highlighted in the search results include:

  1. Public Sector Financing: Cities can use their main revenue sources, such as property taxes, transport fees, and other charges, to finance green infrastructure projects. They can also explore the greening of municipal financial instruments, such as congestion charges, variable parking fees, toll lanes, and split-rate property taxes, to achieve greener urban infrastructure1.
  2. Private Sector Involvement: Public-private partnerships (PPPs) are a common mechanism for involving the private sector in funding green infrastructure projects. In PPPs, the long-term risk is transferred to the public sector, and they can play a significant role in financing and implementing green infrastructure projects1.
  3. Grant Funding: Grant funding, including federal grants, can provide local governments with the resources to implement green infrastructure projects. However, federal grants can be highly competitive2.
  4. Federal Programs: Federal programs that support efforts to reduce water pollution and manage stormwater can provide funding for green infrastructure projects. For example, the Environmental Protection Agency (EPA) provides funding for such projects.
  5. Community Development Funds: Community development money can be used to fund green infrastructure projects because these projects can create jobs, increase economic activity, and increase property values. Urban tree planting and green infrastructure can increase economic activity in a commercial district and property values by mitigating flooding and improving neighborhood aesthetics3.
  6. Transportation Funding: Green infrastructure projects are often eligible for transportation funding because they improve transportation networks by efficiently and cost-effectively mitigating street and alley flooding and create a cooler more comfortable environment for passengers.

A great way to ensure green infrastructure gets built is to set it as a building standard for new constructions and incorporate GI into street layouts and designs.

How To Do Green Infrastructure Cost Analysis?

20190403 152142 green infrastructure expensive Citygreen

To conduct a green infrastructure cost analysis, the following steps can be taken:

  1. Define Green Infrastructure and Public Space: Green infrastructure is the network of green spaces, natural systems, and semi-natural systems that support sustainable communities, while public spaces are places publicly owned or for public use, accessible and enjoyable by all free and without a profit motive.
  2. Cost Benefit Analysis: Measure incremental change relative to what would have happened without action, i.e., the base case. The CBA should only consider the incremental or marginal impact of a program or project. Specify the base case in as much detail as possible and quantify it to set a baseline for the incremental changes in outcomes that are being measured. including identifying the developing options, identifying and forecasting costs and benefits, valuing costs and benefits, identifying non-market impacts, and reporting the results of CBA.
  3. Consider the Costs of Green Infrastructure and Public Space: The costs of such projects include construction costs, costs related to the replacement of capital, and costs related to ongoing maintenance and operation. Cost estimates should be specific to the individual project and reflect the design and conditions associated with the construction and operation of the project.
  4. Value the Benefits of Green Infrastructure and Public Space: The benefits of public space are driven by a range of features, and the framework provides recommended approaches and parameters for valuing these benefits. It’s important to carefully consider the specific benefits associated with the project and apply the recommended parameters accordingly.
  5. Engage with Stakeholders: In addition to using the framework, practitioners should engage with stakeholders, including the department’s subject matter experts and the community to understand the full use case of the infrastructure.

By following these steps, practitioners can conduct a comprehensive green infrastructure cost analysis that takes into account the economic, social, environmental, and cultural costs and benefits of the project.

What are the Benefits of Green Infrastructure?

There are a multitude of benefits related to green infrastructure that cities that consistently invest in green infrastructure are seeing.

Energy Efficiency

Green Infrastructure reduces the cooling demands of households, and buildings through creating shade and transpiration of water through leaves from trees and plants. The NSW government estimates that for each reduction in degree through tree canopy you decrease your energy bill by $13.

Air Quality Improvement

Increasing tree canopy and urban green walls contribute to air quality improvement through capturing of physical and gaseous pollutants, suspending captured particles, emitting environmentally friendly particles like pollen, and disrupting of wind flows through tree canopy.

Water Management

Green Infrastructure can capture water runoff, which reduces the volume of stormwater that needs to be processed and be used to sustain the green infrastructure itself. It additionally improves the water quality of runoff that does reach the waterways.

In the ‘Valuing green infrastructure and public spaces Framework’ from the NSW Government. The estimate the value of stormwater reduction based on the avoided costs of projects to build additional stormwater management infrastructure like wetlands and retention ponds.

Some key data points from that analysis:

  • Cost to manage stormwater flows ranged between $0.04 to $0.30 per cubic metre captured, depending on the type of infrastructure option
  • An average-sized street tree in Canberra captures 16,500 L (16.5 cubic metres) annually
  • A hectare of irrigated urban forest would capture 1 megalitre (1,000 cubic metres) of stormwater per 20 mm rain event

So in summary, the document states green infrastructure and trees can reduce stormwater runoff, avoiding the need for additional “grey” stormwater infrastructure. This avoided expenditure provided an approach to quantifying the stormwater management benefits.

Health Benefits

Green Infrastructure has far ranging impacts in the areas of mental and physical health. Increasing the amount of green infrastructure in the forms of public open spaces, parks, and facilities shows a 6% increase of residence hitting their daily activity goal which equals around a $1.13 cost saving per household per km walked.

Urban cooling through tree canopy and transpiration also reduces heat-related health complications. The NSW Government estimates 1°C of cooling saves $3 per person per very hot day in health costs and an 10% increase in canopy cover is equal to a 1.1°C cooling effect.

We invited General Practitioner Dr. Kim Loo to come speak at our event ‘Where Shade hits the Pavement’ to discuss how trees and urban planning are impacting her patients in Western Sydney.


Despite its complexity, the wide-ranging benefits of green infrastructure unfold gradually over time. While there exists an initial upfront cost during the construction phase, this investment quickly shows substantial returns, growth and impact for the community.

As the effects begin to manifest in the economic, social, and environmental spheres, the return on investment becomes increasingly evident. The transformative power of green infrastructure becomes apparent when measuring its positive influence on economic savings, social well-being, and environmental sustainability.

Therefore, while the initial costs might seem substantial, the long-term advantages and dividends gained from the implementation of green infrastructure undoubtedly outweigh these initial expenses, making it a wise and forward-thinking investment for communities and regions alike.

How Urban Trees Prevent Flooding

20220421 112923 green infrastructure expensive Citygreen

Extreme rainfall events are increasing in frequency and intensity worldwide due to climate change. With intense storms comes a growing concern surrounding urban flooding and its destructive impacts.

Major cities across the globe are searching for solutions to curb flooding damage. Urban trees have emerged as a natural and effective approach to enhancing stormwater management. By providing interception, infiltration, and runoff reduction, trees are powerful tools to mitigate flooding. When combining green and blue infrastructure together such as trees, and stormwater management we can combine these efforts and create a system that is more impactful at reducing runoff volumes and minimizing flood risk.

Understanding Urban Flooding and Its Impacts

Urban flooding occurs when intense rainfall overwhelms drainage systems and flows rapidly across impervious surfaces into buildings, homes, and infrastructure. Impermeable roads, parking lots, and sidewalks combined with inadequate sewer systems lead rainwater to pond and flood key areas, rather than draining naturally.

The effects of urban flooding include destruction of property, closure of businesses and government facilities, disruptions to public transit systems, damage to infrastructure like roads and bridges, and increased risk of injury or waterborne diseases from sewer overflows.

As cities continue to densify and replace green space with concrete buildings and asphalt pavement, and as extreme weather events intensify due to climate change, urban flooding will only become more severe if proactive solutions are not prioritized.

How do Urban Trees Prevent Flooding?

Their root networks, often concentrated within the upper layers of soil, help in reducing surface runoff by enhancing soil permeability and capture. These shallow roots aid in soil structure improvement, preventing soil compaction and promoting infiltration, allowing water to percolate more effectively into the ground rather than running off the surface. By absorbing and storing water during rainfall events, trees can significantly reduce the volume and velocity of stormwater runoff, thereby lessening the risk of flash floods and minimizing the burden on stormwater drainage systems.

Additionally, trees contribute to flood reduction by intercepting rainfall with their canopy. The foliage of urban trees acts as a natural barrier, breaking the impact of raindrops and slowing down the descent of water onto the ground.

This helps to reduce soil erosion and surface water runoff by allowing rainwater to be gradually released, giving it more time to infiltrate the soil or evaporate, consequently lowering the amount of water reaching streets, sidewalks, and drainage systems. In combination with their ability to enhance soil permeability and reduce runoff, urban trees serve as valuable components of green infrastructure, effectively mitigating flooding and contributing to the overall resilience of urban areas against storm events.

The trees will then use the water to nourish itself by evapotranspiration and release oxygen & water vapor back into the atmosphere through its leaves to cool the nearby environment.

The Role of Urban Trees in Stormwater Management

20220421 110124 green infrastructure expensive Citygreen

Urban trees offer a nature-based solution to enhance cities’ resilience against flooding. Their canopies intercept rainfall that would otherwise end up as runoff. Their extensive root systems allow more water to infiltrate into subsurface soils rather than flowing across pavement surfaces. And the added roughness or drag created by trees slows down stormwater that does end up traveling as runoff, providing more time for infiltration and evaporation.

Studies show that just 100 mature tree canopies intercept over 100,000 gallons of rainfall per year depending on the climate. Over an acre of tree cover can reduce runoff by up to 62,000 gallons from a one-inch rainstorm event. When quantified, urban trees provide significant volume reduction benefits to curb stormwater runoff and the resulting floods.

How to Think about Urban Tree Flood Mitigation

stormwater rendering carpark kerb inlet digital size green infrastructure expensive Citygreen

There are four ways urban trees reduce stormwater runoff volumes:

Interception: During rainstorms, tree leaves, branches, and trunks intercept precipitation and absorb or block it from reaching the ground. Interception rates vary based on tree size and structure, climate, and precipitation patterns. But large healthy trees and soil prevent thousands of gallons of water annually from ever forming runoff.

Infiltration: Tree roots and the organic matter from decomposing leaves create small channels and pathways for stormwater to infiltrate into the soil at much higher rates than compacted urban soils.

This facilitates groundwater recharge while preventing rainfall from becoming high velocity runoff. Soil quality and compaction is also an important factor as hard compacted surfaces such as those mainly found in urban areas push the water into the cities municipalities at a greater rate increasing the chances of flooding.

Slowing Runoff: Trees and their structural root networks add surface roughness on the landscape which slows down runoff as it flows towards drains and sewer systems. This slowing effect allows more time for the runoff to naturally infiltrate into soils and prevents high velocity flows that contribute to urban flooding.

Capturing Runoff: Integrating Soil Cells into urban trees is rising in popularity due to the flexibility of the system. You can use permeable surfaces to infiltrate rain water into the pit itself which will hydrate and oxygenise the soil and tree roots.

Once the tree roots and soil have cleaned the water and been satiated, the excess water can filter down into a lower holding chamber to reduce the flow during high peak weather events.

The excess water can be released at a later time into the municipality systems or with proper planning be used for on-site irrigation of surrounding landscapes.

Benefits Beyond Flood Mitigation

In addition to stormwater management, increasing urban trees provides municipalities a number of co-benefits:

Air Quality Improvement: Trees remove air pollutants like ozone, nitrogen oxides, and particulate matter through their natural respiration processes. This leads to improved air quality and public health outcomes.
Related: Best Trees for Reducing Air Pollution.

Energy Conservation: The shade provided by trees reduces summer cooling demands in buildings, leading to energy savings from reduced air conditioning needs.

Property Value Enhancement: Multiple studies confirm that homes and properties landscaped with trees have 3-15% higher property values compared to non-landscaped equivalents, providing a financial incentive.

Mental Health Benefits: Spending time around trees and green spaces improves mental health by reducing stress, anxiety, and depression through both mental relaxation and lowering unhealthy cortisol levels.

Aesthetic Enhancement: Thoughtfully designed green infrastructure and urban tree planting enhances the beauty, visual appeal and livability of neighborhoods by reducing the amount of grey services needed to service the community.

Planting and Caring for Urban Trees

To properly leverage the stormwater management potential of urban trees, care must be taken to plant appropriate tree species and proactively maintain tree health through pruning, watering, and disease management.

Native tree species that can withstand urban conditions like air pollution, compacted soils, drought, and flood tolerance are ideal. Maples, Elms, Oaks, Magnolias and Birches are great options in many cities. Consult with your local government or nurseries to get a list of appropriate trees.

When siting trees, utilities, infrastructure, soil compaction and drainage, and sunlight exposure must be considered to allow sufficient soil volumes for the tree as it grows to maturity.

Consistent watering of young trees is critical, along with pruning once mature to encourage optimal canopy structure. Organic approaches should be used to prevent and manage pest damage.

Permeable Pavements and Soil Cells Enhance Infiltration

While trees alone provide measurable stormwater management, combining them with permeable paving systems and subsurface water-storing soil cells can capture, infiltrate and transpire even more rainfall.

As you can see from the above video, the trees planted in soil cells with the supported above ground infrastructure to direct and filter stormwater into the treepit grow to a better quality when compared to the same tree planted in the nearby grass verge.

Permeable pavements also allow surface runoff to pass through the paving material and filter down into aggregate storage layers underneath where water can infiltrate soil naturally.

Any excess runoff is conveyed into connected tree soil cells – structural stormwater chambers that feeds stored stormwater and runoff directly to trees at the ideal pace for root absorption.

This enables trees to grow stronger, healthier, and larger – which further enhances their rainfall interception capacity. Where possible, cities should install connected permeable pavements and subsurface soil cells in parallel with urban tree planting efforts to maximize stormwater volume reduction benefits.

Assessing Current Canopy Cover

Before embarking on a journey to increase canopy cover, it is crucial to assess the existing canopy cover in the city. This assessment provides a baseline and helps determine the extent of improvement required. There are two primary methods for assessing canopy cover: analyzing satellite imagery and conducting on-the-ground surveys.

Satellite imagery analysis can provide a broad-scale overview of the city’s canopy cover percentage. Several tools and software are available that utilize satellite data to estimate canopy cover. On the other hand, conducting on-the-ground surveys involves physically measuring the canopy cover in different areas of the city. This method provides more accurate and detailed information but requires time and resources.

Setting Goals for Increasing Canopy Cover

Setting clear and achievable goals is essential when aiming to increase canopy cover. The desired percentage increase should be determined based on various factors such as the city’s climate, available space, and community needs. It is crucial to strike a balance between increasing canopy cover and considering other urban requirements.

For example, a city with a hot climate may aim for a higher percentage increase in canopy cover to combat the heat island effect. On the other hand, a city with limited available space may focus on strategically planting trees in key areas to maximize the impact on canopy cover. Engaging with urban planners, environmental experts, and community members can help in setting realistic and effective goals.

Selecting Appropriate Tree Species for Urban Environments

Selecting the right tree species and soil quality is crucial for successful urban forestry initiatives. Not all tree species are suitable for urban environments due to factors such as soil conditions, climate resilience, and maintenance requirements. Researching tree species that thrive in urban environments is essential to ensure long-term success.

Native tree species that are well-adapted to the local climate and soil conditions should be prioritized. These species have a higher chance of survival and require less maintenance. Additionally, choosing a diverse range of tree species helps increase resilience against pests and diseases.

Working with local councils, arborists, horticulturists, and experts can provide valuable insights into selecting appropriate tree species for the city.

Planning Tree Placement Strategically

Strategic tree placement is crucial for maximizing canopy cover and reaping the full benefits of urban trees. It is essential to develop a comprehensive tree planting method that considers available space, proximity to buildings, and shade benefits.

Identify areas in the city where planting trees can have the most significant impact on canopy cover and environmental benefits. These areas may include parks, streets, parking lots, and public spaces. Planting trees near buildings can also provide shade and reduce energy consumption for cooling. By strategically planning tree placement, cities can optimize the positive effects of canopy cover on the urban environment.

Deciduous trees are crucial in creating urban spaces as they respond to the current season and needs of the community. Deciduous trees are trees that shed their leaves, usually during the winter or autumn season where the climate is generally cooler; so you plant deciduous trees so that during the cooler periods the heat from the sun can penetrate into the urban areas to better support and warm the community.

Engaging the Community in Canopy Cover Initiatives

Increasing canopy cover in cities requires the active participation of the community, organizations, and stakeholders. Engaging the public in the process not only creates a sense of ownership but also fosters a deeper understanding of the benefits of urban trees.

Involving community members in decision-making processes and seeking their input can help tailor canopy cover initiatives to meet their needs and aspirations. Additionally, educating the public about the benefits of trees and canopy cover is crucial. This can be done through workshops, educational programs, and resources that highlight the positive impacts of urban trees on air quality, temperature regulation, and overall quality of life.

What are Effective Tree Care Practices?

Proper care and maintenance of newly planted trees is crucial for their survival and healthy growth of urban trees.

Regular watering is essential, especially during the establishment phase, to help the trees develop a strong root system you must water where the tree roots current are. Mulching around the base of trees helps retain moisture, suppresses weed growth, and regulates soil temperature.

Related: How to Promote Deeper Root Growth and Drought Tolerance

Additionally, pruning trees as needed promotes healthy growth and removes any damaged or diseased branches. Protecting trees from pests and diseases through appropriate measures, such as regular inspections and treatments, is also necessary to maintain their health and vitality.

Implementing effective tree care practices ensures that the trees thrive and contribute to the increase in canopy cover

Collaborating with Local Organizations and Stakeholders

Collaboration with local organizations, nonprofits, environmental groups, and stakeholders can provide valuable resources, funding, and expertise for increasing canopy cover. Exploring partnerships and leveraging existing networks can help cities implement their canopy cover initiatives more effectively.

Local environmental organizations may have experience and knowledge in urban forestry and can provide guidance on best practices. Government agencies can offer funding opportunities or technical expertise. By collaborating with various stakeholders, cities can tap into a broader range of resources and support, making their canopy cover initiatives more successful.

Monitoring and Evaluating Canopy Cover Progress

Continuous monitoring and evaluation are crucial to assess the progress of increasing canopy cover in the city. Monitoring the growth and health of trees provides valuable insights into the success of the initiatives and helps identify any areas that require improvement.

Regular assessments of canopy cover increase can be conducted using satellite imagery or on-the-ground surveys. Additionally, evaluating the impact of increased canopy cover on temperature reduction, air quality improvement, and overall quality of life in the city provides a holistic understanding of the benefits achieved. This data can guide future efforts and assist in making informed decisions regarding urban forestry initiatives.

Educating the Public about the Benefits of Urban Canopy Cover

Raising awareness about the importance and benefits of increasing canopy cover is essential to garner public support and involvement. Educating the public can be done through various channels such as social media campaigns, educational programs, workshops, and resources.

Highlighting the positive impacts of urban trees on air quality improvement, temperature regulation, and mental well-being can help individuals understand the importance of canopy cover. Encouraging the public to participate in tree planting initiatives and providing them with the necessary knowledge and resources empowers them to take action and contribute to creating a greener future.

Implementing Long-term Maintenance and Expansion Strategies

Increasing canopy cover is a long-term commitment that requires ongoing maintenance and expansion strategies. Planting more trees and implementing sustainable urban forestry practices ensure the continuous growth and health of the urban canopy.

Trees have lifespans decades to centuries long but urban trees have an average lifespan of just 14 years. One of the main reasons urban trees have such low lifespans is due to poor planting locations and lack of access to soil that grows healthy trees. Our Stratavault product sometimes referred to as a soil vault or soil cells is designed to help trees thrive in urban environments by giving the tree access to high quality uncompacted soil at a high volume.

Types of Green Infrastructure that help Cities the Most


Adding trees to urban spaces, plazas, streets, city blocks, downtown CBDs, is probably the most effective way to cool urban spaces and increase the liveability of our cities.

Trees provide immense benefits to a community, far beyond just aesthetic value. They offer immediate shade to protect against the heat of the sun. Through transpiration from their leaves, they cool surrounding areas. Their root systems and leaves absorb particular matter and pollutants from both air and soil. Trees improve physical and mental health by encouraging outdoor recreation in their cool shade. Increased green canopy has even been shown to sharpen mental cognition.

Additionally, trees support biodiversity by sustaining natural ecosystems. In all these ways, planting the right trees can greatly enhance urban spaces.

Green Roofs

Green roofs can offer similar benefits to trees but add value as they can be planted on roofs to help dissipate the urban heat island effect as a major factor in creating the heat island is the reflection of heat from hardscapes such as cement, roads, and rooftops back into the atmosphere. The installation of vegetation on rooftops, provide benefits such as improved insulation, stormwater management, heat island mitigation, and the creation of urban wildlife habitats.

Rain Gardens and Bioswales

Rain gardens and bioswales are designed to capture and absorb stormwater, preventing runoff and reducing the burden on traditional drainage systems, thereby improving water quality. A new innovation in this space is connecting the stormwater system into the soil cells that hold trees. This gives the trees access to on-site water reducing the need for external irrigation, improves the quality of the water as the tree through its tree roots and soil clean the water of pollutants. Excess water now cleaned by the tree can be stored in a pit under the tree and released back into the cities sewerage system at a later date reducing the impacts of high level rain events and flash flooding.

Permeable Pavements and Green Streets

Permeable pavements and green streets allow water to infiltrate the ground, reducing surface runoff and contributing to groundwater recharge while minimizing flooding risks.

Urban Forests and Tree Canopies

The stormwater management potential of blue-green infrastructure in reorganizing our cities to be more resilient is a powerful concept as we can harness the power of natural processes to capture and filter rainwater right where it falls. Just imagine—rain gardens, green roofs, and bioswales of lush native vegetation growing our city, beautifying neighborhoods while putting stormwater to work!

This approach relies on the water-cleaning talents already found in soils and plants. It’s a decentralized network that keeps working even when one part fails. And it can adapt to handle bigger storms coming our way with climate change as Trees can absorb between 10 and 150 gallons of water daily.

Beyond stormwater perks like less flooding and pollution, blue-green infrastructure also provides habitat, cleaner air, urban heat relief—really boosting quality of life for all inhabitants across our communities.

Implementing it takes some upfront planning to get plant and soil selections right. But once established, the nature-centric approach lets vegetation and microbiology do the water treatment work for us! Plus, the infrastructure cost savings are substantial when you consider the pipe and treatment plant alternatives over the lifetime value of the project because as the trees and green spaces continue to grow the benefits just compound.

At Citygreen we’re convinced blue-green infrastructure is the sustainable, resilient way forward for both stormwater and the livability of our public spaces.”

What is Pavement Lift?

Pavement lift refers to the situation where sections or segments of paved surfaces, such as roads, sidewalks, or driveways, are raised or uplifted unevenly and has been displaced from its original position due to external factors.

What is Root Heave?

Root heave is a phenomenon where tree roots beneath the ground exert upward pressure as they search for nutrients, water and oxygen, causing pavements and urban infrastructure like sidewalks and driveways to lift and crack. This can lead to safety hazards and aesthetic issues, making it crucial to understand and address how to plant a tree to avoid root heave

How to Stop Root Heave?

Preventing root heave is far more effective and cheaper than dealing with it after the fact. By adopting the right strategies and planting techniques below, you can avoid the costly upheaval and damage caused by tree roots, ensuring the longevity of your pavement.

Ways to Prevent Tree Roots Causing Pavement Lift

Safeguarding your sidewalks from tree root damage requires a thoughtful proactive approach before the tree is even planted in the ground. Below we’ve detailed several methods that can be employed to prevent tree roots from undermining the stability of your pavement and urban infrastructure.

Use Soil Vault Systems

Proper Positioning of your Trees

Choosing the right location for tree planting is essential to prevent root-related problems. Proper positioning can minimize conflicts between tree roots and sidewalks, leading to a harmonious coexistence.

Properly positioning trees to avoid pavement lift and reduce conflicts with sidewalks and pavements is a critical step in urban tree management. Start by selecting tree species with non-invasive root systems, and consult with local experts for guidance. Reach out to your local government parks department or urban forester as they will be more then happy to send you a list of trees that are ideal for growing in your local climate.

Maintain a safe distance of at least five to ten feet between the tree base and nearby hardscape, allowing roots to develop without initially compromising pavement stability. Analyze soil conditions to ensure well-draining soil with adequate organic matter, which encourages healthy root growth away from pavements. We recommend using loamy soil but you can see our article on choosing the best soil for your tree here.

Plant trees at the right depth, avoiding shallow planting that may lead to horizontal root spread and deeper planting to promote root growth away from the surface. Regularly monitor root growth patterns and consider professional assistance to assess local conditions and choose suitable species and planting techniques. Well-structured tree pits with features like root barriers and proper drainage can direct root growth downwards away from infrastructure, ensuring a harmonious coexistence.

Related: How do Tree Roots Behave?


tree root bridging to avoid pavement lift and heave

Bridging is a technique that creates a buffer zone between tree roots and pavements. This method involves installing materials that allow roots to grow beneath the sidewalk without causing upheaval. Creating a slope for your sidewalk involves the strategic use of posts, piers, or arch supports. These supports serve as the foundation for laying the sidewalk material, leaving deliberate space for the roots to grow beneath without causing disruptions.

One notable benefit of root bridging is its capacity to preserve existing tree roots, ensuring their continued health and enhancing overall stability. The choice of bridging materials can vary based on specific project requirements, including desired height, repair area length, and available budget. Commonly employed materials encompass wood, concrete, and composite materials.

However, it’s important to note that the design and construction of root bridging can be a relatively costly endeavor. In cases where the bridge elevation aligns with a typical step height (approximately 6 to 8 inches) relative to the surrounding grade, the installation of safety railings may be necessary. In certain scenarios, the incorporation of soil can be employed to seamlessly blend the bridge edge with the surrounding terrain, effectively eliminating any abrupt step-off points.

As root bridging can be expensive and incorporate alot of safety factors, it’s better to plan your tree planting to ensure that the trees roots have the best chance of growing deeper to never distrub the surface.

Root Barriers

reroot barrier used to deflect roots away from pavement

Barriers such as Root Directors or Reroot Barriers are a great preventative measure designed to direct and guide exploring roots down and away from services and infrastructure. They are best installed when the tree is newly planted so when the roots expand and reach the barriers they will be directed deeper into the soil instead of staying in the upper levels of the soil.

Installing Snorkils also help greatly in enticing the tree roots to explore downwards to help avoid pavement lift as the Snorkil gives access to oxygen and water at a lower depth so the roots don’t have to keep near the surface to access the nutrients it needs to survive.

Reinforcing Collars

Similar to Root Barriers reinforcing sidewalks with concrete collars or gravel aggregate helps deter tree roots from growing beneath them, thus preventing damage and upheaval.

Additionally, adding a layer of compacted gravel or pebbles beneath the sidewalk can create a path for tree roots to follow, reducing the likelihood of pavement damage as tree roots prefer to grow in the path of least resistance.

e.g. Trees roots grow faster in uncompacted soil when compared to compacted soil due to the tree having to expend less energy to push through the soil in search of oxygen, nutrients, and water.

Tree Removal

In cases where tree roots pose an imminent threat to pavements, roads or infrastructure; where there is direct safety issues involved, tree removal or relocation may be a necessary but last resort option to prevent further damage.

What to Avoid When Dealing with Tree Roots

Understanding what not to do when dealing with tree roots is as crucial as knowing the right techniques. Certain actions can exacerbate the problem and lead to more significant damage.

For example, removing too much of a tree root could create a void space that can no longer support the above pavement which cause create further issues.

Tree Care Services Can Help Prevent Damage to Your Property

Professional tree care services can provide expert guidance and assistance in managing tree roots and preventing damage to your property. Their expertise can be invaluable in maintaining both your trees and pavements.

Tree Roots Pushing Up Driveway – What To Do

If tree roots are causing your driveway to heave and crack, specific actions can help address the issue, restoring the functionality and appearance of your driveway.

First Signs of Tree Root Damage

Recognizing the early signs of tree root damage is essential to address the issue promptly.

The initial signs of tree root damage to pavements and driveways can vary depending on the severity of the issue, but common early indicators include cracks, uneven surfaces, and pavement shifting.

The most noticeable sign of such damage is often cracking or sections of pavement lift that are uneven or lifted. These issues can pose trip hazards and make walking or driving difficult.

In some cases, instead of uplifting, the pavement may sink or settle due to soil erosion caused by root growth. As roots expand beneath the pavement, they can create an uneven surface or pockets of air below the pavement and make it challenging to walk or drive smoothly.

Advanced cases may even reveal visible tree roots breaking through the pavement surface or pushing it upwards. Additionally, the pressure from tree roots can not only damage the pavement but also lead to cracks in nearby structures like retaining walls, curbs, or foundations.

Plan Ahead to Avoid Tree Root Damage to Urban Infrastructure

Effective planning and design are key to avoiding tree root damage causing pavement lift. By taking precautions during the initial stages, you can prevent future issues.

Top Benefits of Planting Urban Trees

The benefits of planting trees in urban areas are numerous and far-reaching. Trees help to improve air quality by absorbing pollutants such as nitrogen dioxide, sulfur dioxide, and fine particulate matter. They also help to sequester carbon, which is important for mitigating the effects of climate change.

Additionally, trees help to reduce the urban heat island effect, which occurs when cities are significantly warmer than surrounding rural areas due to the heat absorbed and reflected by buildings, pavement, and hardscaped surfaces. Trees combat the heat by providing shade and evapotranspiration, which helps to cool urban areas and reduce the amount of energy required for air conditioning.

Urban trees help increase biodiversity and support local ecosystems, providing habitat for wildlife, including birds, insects, small mammals, and clean the surrounding soil and air of pollutants and particulates. This is especially important in urban areas, where natural green space is often limited and runoff from hardscaped surfaces, infrastructure and cars has detrimental effects to the community.

How to Grow Better Urban Trees

Hear from Ross Clark, the man who wrote the standard on growing trees in Australia. Ross Clark recently spoke at our event ‘Where the Shade hits the Pavement’ on how to grow better urban trees.

Identifying Suitable Areas for Planting Trees in Urban Areas

Identifying suitable planting locations is an important step in planting more trees in urban areas. Areas that lack greenery and could benefit from more trees include parks, sidewalks, residential areas, and public spaces.

For example, Penrith City Council in Australia identified suitable areas to plant urban trees by using heat sensor data, topography mapping and community survey data to review where the most vulnerable in their community lived to determine areas where additional tree canopy cover would be most beneficial and prioritized planting in those locations.

You can review Penrith City Councils full Cooling the City Strategy’  from our Where Shade Hits The Pavement Event here:

How to Choose a location for Urban Trees?

When choosing planting locations, it is important to consider factors such as accessibility, sunlight, and available soil volume and quality. Trees should be planted in areas that are easily accessible for maintenance and receive adequate sunlight, water and soil volume.

Soil volume and quality is absolutely crucial to the success and longevity of urban trees, as trees require well-draining soil that is rich in nutrients and uncompacted to provide space for root growth and oxygen and water the chance to peculate deep into the soil.

Selecting the Right Tree Species for Urban Areas

Selecting the right tree species is crucial for the success of tree planting initiatives in urban areas. Trees that are well-suited to urban environments should be selected, such as those that can tolerate & filter pollution, withstand drought, provide tree canopy and environmental and aesthetic design.

Native tree species that are adapted to the local climate should be prioritized, as they are more likely to thrive and support local wildlife. For example, the Greening Australia initiative in Australia, planted over 500,000 trees, shrubs, and grasses in urban areas using native species.

When selecting tree species, it is important to consider the size of the tree at maturity, as some species may be too large for urban areas and cause damage to the tree, buildings and infrastructure.

There is nothing more disheartening than witnessing a tree’s canopy hacked to accommodate utilities like powerlines due to poor planning. In such instances, both the tree and the community suffer, missing out on the invaluable benefits of a mature tree in the environment.

Moreover, the mismanagement of trees results in wastage of ratepayers’ money, as maintenance workers must continually tend to the space surrounding the infrastructure for the total lifecycle of the tree.

Planning the Urban Tree Planting Process

Best Time to Plant a Tree

Planning the tree planting process involves several important steps. The ideal time to plant a tree is during autumn after trees lose their leaves or early spring before budbreak.

We ideally plant during autumn as tree root growth goes into overdrive, instead of the tree splitting its energy between root growth and canopy growth the tree focuses on expanding it’s fine and structural roots as far as possible when canopy growth is much less of a concern.

The further the fine and structural roots grow and establish, the better the outcomes the tree canopy will experience during the following canopy growth period.

What Soil Should you use for Urban Trees

The type of soil you use and soil preparation is also important to the success of trees in urban areas, as trees require well-draining uncompacted soil that is rich in nutrients.

Proper irrigation is necessary to ensure that newly planted trees receive enough water to establish healthy root systems. At Citygreen we can provide customised soil designed specifically for the trees environment.

Citygreen invited landscape architect Elke Haege Thorvaldson, co-author of the acclaimed ‘Soils for Landscape Development‘ to speak at ‘Where the Shade Hits the Pavement’ about how to design and specify soils for trees in urban locations.

Proper Urban Tree Planting Techniques 

When planting the tree, ensure it is positioned at the proper height and the root crown is at ground level, and the hole is dug to the correct depth to avoid oxygen deprivation that hinders root development.

Confirm the tree stands straight by using a tree anchor and having someone view it from multiple angles before backfilling the hole gently yet firmly, stabilizing the root ball’s base with packed soil. Eliminate air pockets by watering periodically during backfilling.

Only stake the tree if necessary, as studies show that unstaked trees establish faster and develop stronger trunks and roots. Mulch the tree’s base with organic matter to retain moisture, moderate soil temperature, and reduce weed competition.

Newly planted trees in urban areas need additional care during their initial establishment phase. Addition follow-up care is needed in the weeks after such as keeping the soil moist but not waterlogged, watering trees at least once a week, and more frequently during hot and windy weather.

Water must be concentrated on the rootball at the base of the tree as a newly-planted tree can only access moisture that is within reach of it’s roots. We recommend installing a Snorkil system around a newly planted tree to help water & oxygen access the deeper roots. The Snorkil also helps avoid roots trying to surface in search of nutrients as the deeper roots have access to a deeper source of food.

Engaging the Community in the Tree Planting Process

Community engagement is an important aspect of tree planting initiatives in urban areas. Involving the community in these initiatives can help to increase awareness and support for environmental conservation efforts.

Ways to encourage community participation include hosting public events, working with local organizations, and providing educational resources on the benefits of trees and how to care for them. Community members can also be involved in the selection of tree species and planting locations. 

Reach out to your city council and see if they offer a free tree planting program.

Maintaining Planted Trees in Urban Areas

Proper maintenance is crucial for the health and longevity of planted trees in urban areas. Regular watering is necessary to ensure that trees receive enough moisture, especially during hot and dry periods. Pruning is important to remove dead or damaged branches and promote healthy growth.

Monitoring for pests and diseases is also important, as urban environments can be conducive to the spread of these issues. It is important to address any issues early to prevent them from spreading and causing damage to the trees.

Monitoring the Impact of Urban Tree Planting on the Environment

What gets measured gets improved. Measuring the impact of tree planting initiatives in your community is crucial. This involves monitoring the reduction of air pollution, the increase in biodiversity and health of the tree, heat measurements, property values, and increased community activity.

By tracking progress, you can determine the monetary and environmental value these trees bring to the community.

There are several challenges to planting more trees in urban areas, such as lack of space and limited funding or initiative by developers, council . However, there are solutions to these challenges:

City Mandated Tree Plantings for new Constructions: New Constructions and developments must include a minimum number of trees in their designs to ensure that any new constructions are adding environmental value to the community to help combat climate change, and the urban heat island effect.

City Mandated Soil Volumes: Soil Volume is critical to the success of urban trees so city standards must include a minimum soil volume that is adequate for trees to survive once they reach maturity. 

Maintenance Programs: Ensuring the continued care and maintenance of newly planted trees is vital for their survival and growth. However, a challenge arises with tree ownership, responsibility, and care, particularly when dealing with project-based constructions focused on swift project completion and tight deadlines.

It is crucial to establish maintenance programs during the initial contract process. By doing so, we can guarantee that the development and success of the trees are not overlooked or disregarded after the initial planting phase.
