Feedback post on Enhanced swales

Hello, The Cross Section of a Parabolic Designed Swale figure has a side slope labelled as 2:1. I think the labeling of 2:1 is misleading as our municipality (Town of Caledon) had a consultant indicate to the Town that the STEP guidance for enhanced grass swales is a maximum of 2:1, which is not the case (the max slope was 2.5:1 in the 2010 LID planning and design guide and 3:1 in the wiki guide/updated fact sheets). To be more clear in the wiki guide, just sharing a suggestion to either revise or remove the labels in the cross section of parabolic swale, or perhaps a note that the image is to demonstrate parabolic shape and not depict what the maximum side slope should be.
