I realized I spoke with Erica about this and completely forgot to type up all of my comments and send them over to you, sorry!  While there is less than half an acre of impervious proposed on the Hubbard parcel, the total project proposes to create greater than 0.5 acres of impervious area, which is subject to requirements set in the State of Vermont's 3-9050 General Permit. Since this is a public transportation project, the consultant should confirm with the VTDEC Stormwater Program Reviewer for South Burlington whether this project is exempt from the requirements set within the 3-9050 General Permit or if a permit will be required for this project.  As the project proposes to create more than 0.5 acres or more of impervious surface, the project is subject to the requirements of section 13.05 of the LDRs.  The applicant is missing a few of the required documents listed in Section 13.05.C of the LDRs, including the following: o A plan showing drainage area delineations o HydroCAD modelling for the WQv, 1-yr, and 25-yr storms o A plan showing required maintenance of the proposed stormwater treatment and pre-treatment  The cover letter submitted details how the proposed disconnection areas will meet WQv requirements, however there is no mention of the larger storms outlined in the LDRs.  What consideration was given to structural stormwater treatment practices? Was any consideration given to the usage of underground pipe storage for providing detention in larger storms?

More than ½ acre of impervious is proposed therefore the stormwater standards apply. Can you please review ASAP and provide feedback? I am publishing my report next Wednesday morning and it slipped my mind that it might need stormwater review until just now. I’d also appreciate your review of EPSC if you wouldn’t mind taking a quick gander!
