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
Biodiversity in the urban forest is incredibly important to resilience and long-term planning (something we’ve written about extensively, here, here, here, and here, to name just a few). To help designers start thinking about ways to increase diversity, we’re starting a series on some of our favorite species. Many of the species included will be… More
Philip Potyondy is a Sustainable Forestry Coordinator with the Minneapolis Park and Recreation Board. He has a B.S. and an M.S. in urban forestry, and is an ISA Certified Arborist and a TCIA certified tree care safety professional. His Masters Thesis research on the benefits of trees in cold climates has interested us for years,… 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
Susan Day and her team at Virginia Tech published a paper earlier this year about a soil rehabilitation technique called Soil Profile Rebuilding, or SPR. They were looking for a way to rehabilitate soils damaged by land development in a way that would restore their biological function and be more supportive of plant growth. I… More
This post was originally published on the Soils Matter blog. One of soil’s many important functions is to act like a sponge. As nature’s blanket, soil soaks up water that falls as rain or melts from snow and ice. Soil not only stores water, it also helps to filter out pollutants such as nutrients, bacteria,… 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
As landscape architects, we are often under the impression that because we love urban trees and seeing new trees planted, that everyone around us will love these plantings as well. Some city dwellers do in fact welcome trees with great excitement, but others may see the trees as an intrusion of their private space or… More
Using green streets for stormwater management has become popular in many cities because they allow engineers, planners, and municipal officials to integrate water quality and regulatory compliance with pedestrian access, safety, traffic calming, multimodal transportation, enhanced community livability, urban greening, aesthetic improvements, and better air quality. The multifaceted benefits of Greet Streets are undeniable, but… 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
