Many readers of this blog may already be aware that the Environmental Protection Agency recently started a national rulemaking process with the goal of creating a new program to reduce stormwater runoff. To prepare for this process, they put out a request for information about projects utilizing green infrastructure design techniques that mimic natural stormwater processes (evapotranspiration, infiltration,… More
This EPA webinar was recommended to me by my colleague Sarah. She said Daniel Christian’s talk was a straight-forward overview of design and construction considerations and basics of green infrastructure.
Last weekend I went on a biking tour of the trees in the Mission District of San Francisco hosted by Friends of the Urban Forest and the SF Bike Coalition.
Last week Graham and I stopped by a Silva Cell installation as it was going in to the ground at Mitchell Library and Community Center (3700 Middlefield Road, Palo Alto, CA).
Want to tour a sustainable sidewalk in Toronto? Now you can. It may not look like much from the street, but this is one of our most exciting Silva Cell projects — a pilot proof-of-concept demonstration along The Queensway that is analyzing green infrastructure at work. Join us for the free tour on Thursday, October 6th, from 3 –… More
Many of DeepRoot’s products are defined by their mil thickness. Our Geomembranes (Water Barrier and Bamboo Barrier), for example, have varying thicknesses of 30, 40 and 60 mil, while our root barriers are all 80 mil thick. But what is a mil?
We want to know more about you! (I guess that makes us the Caterpillar, and you Alice.)
This hydrograph (diagram showing runoff flow versus time) compares the intense spike of a stream during a storm in an urbanized watershed without adequate controls, with the “gentle rolling hill” appearance of a forested watershed’s response to the same storm. Note the loss of dry weather base flow for the stream in the urbanized watershed…. More
Trees and other plants provide amazing fodder (compost?) for the imagination. This is a wonderful thing, although it can have mixed results — something we’ve talked about before.
I get several calls a week from the weekend warriors working on various home improvements. Often these improvements relate to cutting tree roots and some type of hardscape (such as sidewalks, driveways, foundations, and retaining walls). The first thing I suggest is that the homeowner talk to an ISA Certified Arborist before doing any sort… More
