The Stormwater Section (City) has reviewed the “McAllister Subdivision” site plan prepared by Krebs & Lansing, dated Jan. 13, 2020. We would like to offer the following comments:
The proposed project is located in the Potash Brook watershed. This watershed is listed as stormwater impaired by the State of Vermont Department of Environmental Conservation (DEC).
The project proposes to create an additional 5466 square feet of impervious area on the parcel. This results in less than 1 total acre of impervious area on the parcel.
Has the applicant completed a downstream analysis for the 25-year storm event in accordance with §12.03.E(3) of the City’s Land Development Regulations?
The VT ANR Natural Resource Atlas wetland advisory layer shows possible Class II wetland located along the eastern border of the lot. Has a delineation been performed for this site?
Please provide information related to the wetland delineation that was completed for this project. This should include the date of the delineation.
Section 12.02(E)(2) of the City’s Land Development Regulations indicates that encroachment into Class II wetlands is permitted by the City only in conjunction with issuance of a CUD
by the Vermont DEC.
Section 12.02(E)(3) of the City’s Land Development Regulations provides restrictions to encroachments into class II wetland buffers, class III wetlands, and class III wetland buffers.
The DRB should request information as needed to confirm that appropriate erosion control and construction methods are being utilized so that conditions set forth in this section are
satisfied.
The applicant should include snow storage locations on the EPSC site plan.
Work in the City Right of Way (ROW) requires a permit before construction can begin. A “Permit to Open Streets or Right-Of-Way” can be obtained from the South Burlington Department of
Public Works on their web site, or by stopping by their office located at 104 Landfill Road.
Silt fence appears to be located on the upslope side of the disturbance but does not adequately protect the downslope side. Please ask the applicant to modify the EPSC recommendations
to accurately protect the downslope areas.
Thank you for the opportunity to comment.
