Biodiversity in the urban forest is incredibly important to resilience and long-term planning. 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 underused. Some may not be underused, but included anyway because they have so many great… More
There are now dozens of open-source tree maps in communities worldwide. The most successful mapping projects are those that provide citizen scientists with simple guides on how to accurately identify tree species and assess tree health. The more accurate the information on the tree maps, the more accurate the green infrastructure calculations they produce – and the… More
Silva Cells were originally developed to provide adequate tree rooting volumes even in areas dominated by pavement. They do this by extending rootable soil volume under HS20 load bearing surfaces. These rootable tree volumes and the large trees that root in them are also an efficient sustainable stormwater management system. Sometimes people ask us if… More

Water pollution is a serious problem worldwide, whether in rivers and lakes or massive oceans. After the famous Cuyahoga River fire of 1969, environmental regulations were put into place in the U.S. which have helped curb the amount of pollutants we put into our water and reversed some, but not all, of the problems stemming… More
Soil structure (how soil particles are held together to form larger structures within the soil) is recognized as an important property of a healthy soil. Grading, tilling, soil compaction and screening soils during the soil processing and mixing process damages structure. To counteract the loss of structure, specifiers then add to it, utilizing a mined… More
Over 20 years ago, the City of Del Mar along the southern California coastline began a citywide process to improve streetscapes with the intention to preserve and enhance the tangible qualities of the community. In 2019, construction began of the downtown streetscape portion, which will bring these concepts to fruition, building up the commercial center of… More
Unmanned Aerial Vehicles (UAVs) or “drones” evoke a variety of responses from people ranging from anger over privacy invasion to awe over the new perspectives on our world. But like the Force, drones are merely tools that can be used for either the Dark Side or the Light. My interest in drones is related to… More
Last month’s blog was the first in a series that focuses on maintenance considerations for Green Infrastructure (GI) systems. We touched on how the design of GI systems should be guided by maintenance funding, equipment, material, staff, and frequency. We saw how early consideration of operations and maintenance (O&M) factors can streamline feasibility assessment, refine… More
