What's New?
September 7th, 2011 - Research Alert: Are Wet Pond or Wetland Sediments Toxic?
Researchers of North Carolina State investigated whether the sediment from wetland sediment ponds was toxic to both land and aquatic life. McNett & Hunt sampled 30 wet ponds and wetlands across the state of NC to determine their results. Click to read more...
September 6th, 2011 - Nutrient Accounting Methods to Document Local Reductions
CSN has just released a draft technical bulletin for external peer review. Technical Bulletin No. 9 synthesizes existing research on nutrients in stormwater and the performance of different stormwater BMPs in removing them. The bulletin also proposes interim removal rates for more than a dozen urban BMPs, and outlines simple computational methods to do nutrient accounting. Click to read more...
August 30th, 2011 - Don't Miss the Most Important Stormwater Conference of the Year!
The 5th National Low Impact Development Conference (LID) is focused on bringing together the technical community to share ideas on how to build our cities while protecting our environment. The concept of LID is to simply not create the problem, and to utilize the natural environment in addressing changes to the water quality and quantity. Click to read more...
August 14th, 2011 - CSN Joins EPA as Urban Stormwater Coordinator
Tom Schueler of CSN will be working with EPA Chesapeake Bay Program and its restoration partners to coordinate with local, state and federal stormwater managers to accelerate the implementation of cost effective sediment and nutrient reduction practices for urban and suburban lands across the watershed. Under the six year cooperative agreement, CSN will provide technical coordination and assistance to help stormwater managers achieve their target load allocations under the Chesapeake Bay TMDL.

July 28th, 2011 -Research Alert: Thermal Impacts of Stormwater Practices
New research from U of New Hampshire confirms that, in test sites in Durham, NH, some surface stormwater practices such as dry ponds and wet ponds can significantly heat up water, often to levels that are harmful to trout and other aquatic life that inhabit cold-water streams. However, the research team also discovered that some stormwater practices were thermally neutral, and could protect cold-water fisheries. Click to read more...

CSN releases turf cover estimates for the Chesapeake Bay watershed
New research conducted by CSN and USGS reveals that nearly 10% of the land area in the watershed is devoted to turf grass, of which about 75% are home lawns. Turf is the fastest growing land cover in the Bay watershed, and currently exceeds the land use for row crops, hay and alfalfa and pasture, respectively. The research is profiled in Technical Bulletin No. 8, which also discusses key water quality management implications of this suburban trend. Click here to download a copy.
CSN Releases Technical Bulletin 7
After several years of development and testing, CSN has released a generic version of the Stormwater Benchmarking Tool for Industrial, Municipal and Federal Facilities in the Bay Watershed. This tool guides you through a comprehensive assessment of your site to discover stormwater problems and retrofit opportunities, based on 22 stormwater benchmarks. Click to read more ...
Chesapeake Bay Stormwater Training Partnership Launched
Are you puzzled by all the new stormwater regulations and practices in your state? Are you uncertain on how to design, install or maintain them? Then, by all means, check out the new stormwater training website. Click to read more ...
CSN Website Changes
Perhaps you may have noticed our new look for the website - we hope to be adding more content in the months to come. We have also made a major shift in how to communicate with each other. You no longer need to join our website, but can subscribe to a new stormwater group through the Chesapeake Network, where you can post news, messages and announcements to other stormwater geeks like you. Click to read more ...
The Chesapeake Stormwater Network advocates for reform of federal, state and local laws, permits, regulations and design manuals to promote more sustainable stormwater management in the Chesapeake Bay. The interactive network aligns and integrates the efforts of thousands of individuals working on the stormwater problem across the Bay. For more about CSN, click here.
