Municipal Sewer and Water Magazine has published an article on maintaining stormwater management that includes some pics provided by us. The issue is not online as of this writing, so you we’ve provided a PDF to view at the below link. The article was written by our friends at BMPClean.org.

Environmental Site Design (ESD) Practices Report – South County Library
December 30, 2009We provided site and stormwater design services for the Anne Arundel County South County Library expansion in southern Maryland a few years ago. An “in the neighborhood” site visit today found that construction was completed earlier this winter. The design accomplished all stormwater management (including retrofit of un-managed areas due to Chesapeake Bay Critical Areas requirements) with Environmental Site Design (ESD) practices. The practices focused on careful grading of both impervious and pervious areas, resulting in impervious area disconnects and wet swales. A series of videos follow that walk through the practices follow.

December 17, 2009The EPA has spoken
December 15, 2009The EPA has published “Effluent Limitations Guidelines and Standards for the Construction and Development Point Source Category; Final Rule” which will dramatically change sediment control throughout the US over the next 4 years. We are still reviewing, but most significant is the require to sample discharges from construction sites and to meet numeric effluent limits that include turbidity. Use of flocculants is pretty much mandatory on sites that are over 10 acres.
It looks like the turbidity limit is 13 nephelometric turbidity units (NTUs) – which is just about crystal clear. The following photo shows 5, 50, and 500 NTUs. Construction runoff will need to be very close to the sample on the left. This will be a complete game changer for sediment control.
