Compost in Green Infrastructure Soil: Too Much of a Good Thing? Part I.

Significant portions of compost are an essential part of many bioretention and other green infrastructure soils. Compost is a beneficial complement to the largely inert aggregate used to provide rapid infiltration in these mixes: It stores significant moisture—reducing peak and total flows, has a high capacity to trap nutrients and contaminants, and boosts the biological...

Stopping Water Pollution in its Tracks: Nitrogen, Phosphorous, and the case for stormwater management

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...

Treating Hydrocarbons with Green Infrastructure

I’ve always believed in nature’s processes to manage compounds in the environment. Even as a young undergraduate engineer, I often wondered why we were removing natural systems like trees and soil rather than working with them, why we weren’t protecting and bolstering those systems in ways that enhanced their natural mitigating processes. The (relatively) recent... More

Long-Term Use of Bioretention for Heavy Metals Removal

Bioretention has been shown to effectively remove heavy metals from stormwater runoff, which makes it a very useful design tool. However, there are two common concerns related to long term use of bioretention for heavy metals removal: (1) When will breakthrough occur, i.e. when will the binding sites be saturated so that dissolved heavy metals...

Tree Roots Improve Soil Infiltration Rates

As discussed in previous blogs, tree and soil provide stormwater benefits in many different ways: Cleansing:  Trees clean stormwater through many different mechanisms, including filtration, adsorption, and plant uptake. Interception: Interception is the amount of rainfall temporarily held on tree leaves and stem surfaces. This rain then drips from leaf surfaces and flows down the... More

Writing Bullet Proof Resistant Soil Specifications

Writing Bullet Proof Resistant Soil Specifications By Howard Stenn, Stenn Design Soil specifications with unnecessary, contradictory or unverifiable standards are an invitation for plant and drainage problems, project delays, and ensuing conflicts over responsibility. Problematic provisions often accumulate in office specifications—added for a particular project or not removed when a divergent section is added –and... More
