Happy Monday CSNers! We wanted to brief you about some cool webcasts we have coming up in the next couple of weeks, starting with one this Thursday on 'Performance Enhancing Devices for Best Management Practices'. We don't like PEDs in our athletes but we may be willing to look the other way if they could be used in our BMPs to improve pollutant removal.
In two weeks (Nov. 3) we'll be debuting our recently developed "Pond Protocol" where you will learn how to rapidly inspect stormwater ponds using visual indicators to assess dam safety and water quality functions in both wet and dry ponds, establish numeric criteria that trigger critical pond repairs or retrofits, outline the range of pond management choices to restore, maintain or enhance water quality functions and finally create a system to make cost-effective decisions to manage the local inventory of legacy stormwater ponds to maintain dam safety and optimize pollutant removal.
And in just 4 weeks we will be going over the newly approved Urban Tree Canopy credit or how to get TMDL credit for planting trees in the Bay watershed.
Can we get more reductions from our stormwater BMPs? We all know that in the Chesapeake Bay stormwater BMPs that are built to the Bay state design specs are credited with removing nutrients and sediment based on the amount of runoff treated per impervious cover …but what if we can tweak the designs of BMPs to remove more of one pollutant or another?
Recently, the Chesapeake Stormwater Network along with some help from Hirschman Water & Environment, LLC conducted a literature review to determine the ability and extent by which “performance enhancing devices” (PEDs) can provide incremental removal of urban nutrients (phosphorus and nitrogen), compared to existing practice designs. Examples of PEDs include adding various amendments to filter or bioretention media and incorporating an internal water storage (IWS) zone in the underdrain system.
As Part 1 in a three part series, this webcast will summarize the findings of the literature review on PEDs for BMPs and present new monitoring data collected by the Center for Watershed Protection on the effect of adding Biochar into bioretention and sand filters. Part 2 of the webcast series (tentatively scheduled for Dec. 8) will bring other experts in the field to provide other Perspectives on Research of LID Performance Enhancement while Part 3 will present recommendations for crediting PEDs through existing Chesapeake Bay protocols.
Tree planting is a popular activity in the Chesapeake Bay watershed done by many local jurisdictions, watershed organizations and other groups, as well as State and Federal governments.
In 2015, a Chesapeake Bay Program expert panel was formed to evaluate how sediment and nutrient removal credits are calculated for expanded urban tree canopy. The newly adopted BMP credits include two BMPs: 1) Urban Tree Canopy Expansion and 2) Urban Forest Planting. These BMPs replace the current urban tree planting BMP for the Phase 6 Chesapeake Bay Watershed Model.
Are you aware that we record our webcasts and archive them on our website so that you can use them to discipline your children...er, um I mean watch them later on when you have more time? Well we do! So far this Fall we have offered webcasts on the following topics:
Hold onto your BMPs everyone...we are getting ready to launch the next installment in the Best Urban BMP in the Bay Award - or the BUBBAs! To find out more about this award contest for BMPs that have been built and installed in the Chesapeake Bay watershed within the last 5 years...head on over to our website here.
To give you an idea of what makes a BMP 'BUBBA worthy' you can watch short videos here on the first place projects in each category from the 2015 contest.
If you'd like to check out some of our past winners or just need an idea for a home project to do this weekend you can do that for each of the past two contests here: 2015 and 2014.
As always, we would like to extend a huge THANK YOU to this year's sponsors - with their support we are able to bring you this contest once again. Please take a moment to check out their websites by clicking on their logos and following the links to their websites.
If you are interested in sponsoring the 2017 BUBBAs, you can still do that. Just download the application here and send the completed copy to Cecilia Lane, email@example.com.
