Introduction Why are streetlights and sidewalks considered municipal assets — but not trees? Most cities manage detailed inventories of their physical infrastructure: light poles, sewer lines, benches, trash bins, snowplows. These things are logged, valued, maintained — and budgeted for. They’re viewed not just as integral components of the public realm, but as long-term investments… More
DOWNLOAD A 1-PAGE PDF VERSION OF THIS CONTENT HERE Future-Proofing Your Stormwater Projects The UK’s updated SuDS standards, released in June 2025, outline clear priorities for managing stormwater in new developments — these principles include managing runoff at the source, mimicking natural drainage, reducing flood risk, improving water quality, and supporting long-term biodiversity and amenity….

Introduction Silva Cells grow healthy trees and manage stormwater in built environments all over the world — but there’s something especially meaningful about Silva Cell projects on school and university campuses. These spaces are more than just places to pass through — they often feel like a second home for students, faculty, and staff, who… More
Introduction Silva Cells were the first commercial soil cell product on the market, but did you know the idea of suspended pavement systems date back many years to urban European streetscapes? From Paris and London to Boston and Redwood City, let’s take a brief tour through the use and evolution of suspended pavement systems throughout… More
Introduction For decades, the assumption has been simple: screened soil is better soil. It’s cleaner, more uniform, easier to manage — and is often seen as the gold standard. The golf industry, for example, has wholeheartedly embraced the properties of EPA-approved screen soils. But here’s the problem: in the pursuit of consistency, we’re sifting away… More
Introduction In traditional site design, managing stormwater often means carving out space for one massive underground tank. These vaults are designed to collect and hold stormwater until it can be slowly released or treated — but they come with major spatial and logistical challenges. In today’s urban environments, with space at a premium and infrastructure… More
What is the role of green infrastructure within stormwater management? This is an important question — and one that Sahil Sharma, stormwater engineer and founder of strmwtr inc, thoughtfully discusses in his recent chat with DeepRoot content manager Jacob Westlin. Below are some of his insightful themes and quotes — but be sure to check… More
Introduction One of the primary environmental challenges of new developments is the increase in impervious surfaces, which, when it rains, leads to more polluted stormwater runoff. Clean water is essential for human health, ecosystems, and sustainable cities — and when rain falls on streets, sidewalks, and rooftops, it picks up contaminants and carries them directly… More
Introduction For decades, cities have relied on gray infrastructure — stormwater pipes, culverts, and treatment plants — to manage urban stormwater. While these systems serve an essential function, they are increasingly overburdened, expensive to maintain, and ill-equipped to handle modern climate challenges. Heavy rainfall overwhelms drainage systems, pollutants flow freely into watersheds, and aging pipes… More
Increasingly Extreme Weather Extreme weather events are becoming more frequent and intense, with cities across the globe facing dangerous challenges from hurricanes, heavy rain, and flash flooding. The combination of climate change and rapid urbanization has made stormwater management a critical component of climate resilience. Traditional stormwater infrastructure, built to whisk water away as quickly… More
Introduction When competing for space in urban development, stormwater management solutions — particularly those such as “daylighted” raingardens with prohibitive footprints — often find themselves at the bottom of the priority list. And yet, as cities expand, impervious surfaces multiply, increasing runoff and overloading drainage systems. So, how do designers simultaneously satisfy development needs and… More
Stormwater Management: Conventional Wisdom The traditional approach to stormwater management in urban environments has been to treat it as a problem to be managed, a liability that cities must control to prevent flooding, pollution, and infrastructure damage. Cities have been built upon this principle: quickly removing runoff from urban areas, directing it into storm drains,… More
