In dense urban areas, implementing stormwater management systems large enough to support healthy trees can be challenging given the multitude of street uses and the high volume of pedestrian, bicycle, and vehicle traffic. One option for providing stormwater control without impacting competing surface needs is using a suspended pavement system like Silva Cell. Solutions like… More
We’re very pleased to announce that the Silva Cell has been approved by North Carolina’s Department of Environmental Quality for use as a credited nutrient removing stormwater control measure (SCM). The Silva Cell is actually the first applicant to be approved by NC DEQ under the New Stormwater Technology (NEST) Program. As the celebration begins… More
Historically, the best way to plan for future storms has been to look at the past. Significant effort has been put into to developing long-term rainfall records, and many of the most complex stormwater models are designed to run simulations that represent decades of rainfall data. But a changing climate means that storm patterns are… More
As engineers and landscape architects working in the built environment, we are increasingly faced with retrofit situations that must work with and around a variety of existing conditions and constraints. As stormwater requirements increase, requiring more storage or larger footprints, we must think creatively to locate and design systems to fit into an already constrained… More
Why do we have green infrastructure? Is it simply a better way to manage stormwater in our cities – or are do regulatory drivers relating to stormwater discharges encourage its use? What are the impacts of our federal regulatory structure on market demands? All of these questions are related. If you live in a medium-sized… More
Impervious cover associated with roadways, parking lots, sidewalks, and rooftops feels necessary for the needs of people in the built environment, but can destroy the ecological integrity of the receiving streams that must accommodate all the associated runoff. Stream or river health is closely linked to land-use activities and pollutant management practices (or lack thereof)… More
Green Streets have become a more common feature of the urban landscape in cities and towns across the United States and abroad. And for good reason: they provide substantial value in community aesthetics, redevelopment, livability and environmental compliance. You may know from personal experience or previous blog posts that water resources and ecological engineers use… More
When we talk about the value of urban trees and soils as a stormwater management tool, the contribution of the trees is often considered secondary. Soil will, of course, store significant amounts of runoff all on its own. However, new research at the Morton Arboretum in Lisle, IL, has found that trees actually provided the largest… More
If you are a regular reader of this blog, then you know we’ve had a recent spate of articles about biochard – from its history, to a discussion of possible applications and controversies, to a question-and-answer following a recent webinar about what designers need to know about the product. Because of the tremendous potential for… More
Healthy trees can grow anywhere, including cities, provided they receive enough water, soil, and sunlight. Research shows that vigorous urban trees keep people healthier, cool cities in summer, warm homes in winter, help kids learn better, decrease car accident rates, raise real estate values, and decrease crime dramatically. Even with these myriad benefits, recent heat… More
Soil. Stormwater. Sustainable Infrastructure.
