The phosphorus manual and worksheets are now ready for use. It is not yet in its final format and is still a draft; however you may use it for your designs. Please provide us your comments and any suggested changes. <> <> We have been approving a new version of the filter BMPs which is the direct infiltration and filtration of roof runoff at the dripline edge of a roof. The following guidelines establish the general standards by which you need to design these structures. Again, let us know what you think. <> We have also started to see a few pervious pavement designs and artificial turf athletic fields. These are the designs to use if you would like to use one of these structures. <> There will be more to come such the design standards for green roofs, Stormtreat and the Contech filter system.

I have a question on the "treatment filter" section of the design criteria. This section indicates a minimum thickness of 4 inches for filter media. The accompanying detail shows 12 inches of soil filter media. Please confirm minimum thickness. Patrick L.
