From the “Other Interesting Stuff” category, a pretty amazing display of a slope failure in Tennessee.

November 12, 2009 by stormwaterThe Flocculants are coming!
November 5, 2009 by stormwaterMaryland just released their draft of a revised erosion and sediment control manual. Included is the use of flocculants to control erosion and to treat for turbidity. Turbidity has been pretty much ignored by mainstream sediment control, as it can not be controlled by traditional traps and filtering methods, especially in runoff from clayey soils. Several other states have already included flocculants as a construction phase Best Management Practice (BMP).
We are ramping up to provide technical and design services, and products, related to flocculants throughout the Mid-Atlantic in the future. Look for a new site, www.floccs.com, as we get closer to going to market.
Steve and Seva Iwinski of Applied Polymer Systems, Inc. have done much groundbreaking work in this field and have been a great help. We look forward to becoming a distributor of their products. Steve has shared a pretty impressive video on flocculants. Check it out: On the left is bare soil that has been treated with flocculants. The right is just bare soil. The rainfall is a 10 inches per hour simulation.
More to come in the future about this exciting technology.

Environmental Site Design (ESD) Presentation
October 27, 2009 by stormwaterOur friends at Hord | Coplan | Macht kindly extended an invitation to present an overview of the forthcoming regulations and design guidance in Maryland that requires the application of Environmental Site Design (ESD) on all projects. This is a turning point for stormwater design and represents a significant change in how sites will be designed in Maryland.
Overlooking the Baltimore Harbor on a rainy day – no better place or time to talk about stormwater management! Many HCM clients and staff attended – it was a very productive couple of hours. Check out the presentation:
We are already working on projects under these new regulations, which will go into effect in May, 2010.
Contact us here if you’d like to have a group that would be interested in having us present this information.
Arid Stormwater
October 15, 2009 by stormwaterThis last year when we were in Arizona, we posted thoughts from a purely East Coast perspective. Read it here.
Interestingly, we just happened upon a very comprehensive video of Arizona’s appraoch to managing stormwater in an arid environment. For stormwater fans, it is well worth the 40 minutes viewing time.
Check it here.
Baltimore Waterkeeper Trash Bash
September 17, 2009 by stormwater
The Annual Baltimore Waterkeeper Trash bash is this Saturday at Nick’s Cafe in Baltimore. Last year it was a blast and they are cranking it up this year even more. Should be quite the party! Come join us!

Global Warming – Is it real?
September 14, 2009 by stormwater
In an effort to start a dialogue (ie, stir things up) a friend we will call “Bill” has a habit of raising the question -
Is Global Warming really happening?
