HomeMy WebLinkAboutSD-21-19 - Supplemental - 0600 Spear Street (22)1 Marla Keene From:Tom Dipietro Sent:Thursday, March 24, 2022 3:45 PM To:Marla Keene; Dave Wheeler; Adam Cate Subject:RE: SD-21-19 600 Spear St - technical review Marla, Below are my comments on the proposed 600 Spear St project:  Provide a detail for the RRFB’s at the Spear street crossing so that DPW can confirm that the proposed equipment is compatible with other equipment installed in the City. This work will require a ROW permit from DPW.  The crosswalk at Spear Street shall be illuminated by a street light. Provide fixture details along with photometrics for this ped crossing.  Stormwater treatment areas (including grading) shall be removed from any proposed future City ROW.  The City shall be offered an Irrevocable Offer of Dedication for the proposed new city street. The City may not choose to exercise this Offer until such time that the street connects to future public streets. As presently constituted just within this development, the streets serve more as an internal drive than a city street that exists for the good of the general public.  Based on the plans submitted, it appears as if the applicant’s intent is for the wastewater pump station and force main to remain private. If this infrastructure is to be considered for future public ownership the pump station location will need to be revised to facilitate future connections and maintenance. The force main is currently proposed to run through a solar field, which would be problematic if repairs are necessary. The wastewater force main discharge point is proposed on the east side of the interstate at the end of the City’s ROW for Oakwood Drive. Has the applicant coordinated with the State of Vermont regarding the proposed location of the force main? This proposed manhole on Oakwood Drive is the point at which the City would assume responsibility for this infrastructure. In order to install this manhole the applicant will need to obtain a ROW permit from the DPW.  Evaluate the proposed location of the gravity sewer system. Can it be situated to facilitate future connections within the proposed new City street?  Evaluate the layout of the stormwater drainage system that is proposed. Are sufficient storm drains provided to collect and convey stormwater runoff from the proposed City street? A storm drains is located in the middle of an intersection in vehicle tire tracks instead of placed along the curb. There are potentially conflicts with UG lines. Insufficient drainage and excessive puddling would be a reason that the City does not accept this road in the future.  The sidewalks running north – south along the proposed “new city street” shall be extended to the northerly property lines  The water line running north-south along the proposed “new city street” shall be extended to the northerly property line.  All pavement markings on sections of street proposed to be public shall meet the VTrans spec for durable markings, Section 646.07, of the VTrans 2018 Standards.  Provide civil details.  Have the applicant confirm the material and width of all proposed sidewalk/path. It appears that the sidewalks in the proposed new City street are of varying size. 2 Thank you for the opportunity to comment. -Tom Thomas J.

This application was originally heard back in July, everyone reviewed it, and then they made pretty major changes but the essential flavor of the development is unchanged. I only received their revised materials last Friday, and unfortunately forgot to send them to you until just now. I’m working on cleaning up the project folder so give me like 30 minutes before you start opening things, but could you provide preliminary comments by Thursday of this week? They’ll be back in for final plat so we can look at fine details then. I have a hard deadline of 11AM Friday for finishing my report since I’ll be heading out for a few days at that time. \\city-adserver\apps\USERS\Planning & Zoning\Development Review Board\Applications\2021\SD-21-19_600 Spear_VonTurkovich_PP_2021-07-20 Marla Keene, PE Development Review Planner City of South Burlington 180 Market Street South Burlington, VT 05403 (802) 846-4106 www.southburlingtonvt.gov 3 Notice - Under Vermont’s Public Records Act, all e-mail, e-mail attachments as well as paper copies of documents received or prepared for use in matters concerning City business, concerning a City official or staff, or containing information relating to City business are likely to be regarded as public records which may be inspected by any person upon request, unless otherwise made confidential by law.
