The Three Keys to Successful SuDS Implementation
Sustainable Drainage Systems (SuDS) are most effective when they are treated as a core part of urban design rather than a technical exercise that sits at the edge of a project. Too often, surface water is addressed late in the process, once layouts are fixed and space is limited. At that point, options narrow and […]
The Critical Role of Interlocking Soil Cells in Urban Tree Infrastructure
Designing urban landscapes that successfully support both healthy tree growth and the structural needs of pavements, pathways, and vehicle areas is a complex engineering challenge. Beneath the surface, the soil cell system plays an essential role in meeting these demands. Its ability to bear static loads, resist lateral forces and preserve large volumes of uncompacted […]
Nature-based SuDS should be the default. What’s holding them back?
For more than a decade, the UK has broadly agreed on the direction of travel for surface water management. Policy documents reference it. Guidance supports it. Demonstration projects prove it. Designers increasingly understand how to deliver it. And yet, across much of England, nature-based Sustainable Drainage Systems (SuDS) are still often delivered through planning negotiation […]
Building Urban Drainage Resilience Through Distributed Solutions
Our existing urban drainage systems are being asked to do far more than they were ever designed for. Denser development, hard landscaping, population growth and increasingly intense rainfall are combining to expose a fundamental weakness in traditional sewer networks. The symptoms are now familiar: surface water flooding that appears without warning, wastewater assets pushed beyond […]
Root Girdling and Why Context Matters
When the phrase root girdling appears in a specification meeting or planning discussion, it tends to stop the conversation cold. The challenge is that the term is often used loosely – sometimes to describe any visible change in root direction or diameter – when, biologically, true girdling is a very specific (and thankfully fairly uncommon) […]
Urban Trees Are Not Just For Christmas
Each winter, towns and cities adopt a more festive character. Streets are illuminated, markets appear, and in many public squares a temporary Christmas tree becomes the focal point for seasonal gatherings. These installations bring warmth and atmosphere, but by early January they are dismantled and the space returns to a familiar hard, gray condition. This […]
How to Plant Street Trees Around Utilities Without Damage
Urban environments are complex, high-demand spaces where every inch of land serves a function. Yet even in densely built areas, greenery is not optional — it’s essential. Street trees do far more than beautify communities. They improve air quality, mitigate urban heat, support biodiversity, intercept rainfall, stabilize soil, and contribute to healthier, more resilient neighbourhoods. […]
Proven Science Still Matters for Urban Tree Soil Systems
As cities continue to expand and the drive for greener, more liveable environments grows, the importance of healthy urban trees has never been clearer. Yet, for all the investment in tree planting schemes, long-term success rates vary dramatically. Some schemes thrive for decades, while others fail within a few years. What often separates success from […]
Building Climate Resilience into our Street Trees
It may feel counter-intuitive to discuss heat stress as the nights are starting to turn colder, but the climate change data is unambiguous: hotter, drier summers and shorter, more intense downpours are here to stay. With this in mind, Forestry England recently released a new ‘species for the future’ list of trees most likely to […]
Thoughtful Design Means Trees Thrive Near Utilities
Urban environments are complex spaces where every inch serves a purpose, yet greenery remains essential. Trees do more than beautify streets; they improve air quality, reduce urban heat, stabilise soil, intercept rainfall and create habitats for urban wildlife. Beyond environmental benefits, trees enhance social well-being, offering shade, encouraging outdoor activity, and improving mental health. Economically, […]
