Re: Existing Commercial Plaza at 63 Quaker Road, Tn of Queensbury
JE 16-048
Dear Craig,
This letter pertains to drainage and stormwater management as it is impacted by proposed improvements
to the existing plaza (formerly known as "Mark Plaza") at 63 Quaker Road. Those improvements are
depicted on architectural plans entitled "63 Quaker Road, Proposed Site Plan" prepared by KPB
Architecture, PLLC, dated 12/15/2016.
Our review of the existing plaza suggests that formal stormwater management on the site is very limited.
Two drop inlets are present in the parking lot along the west side of the building, and other than that,
parking lot runoff appears to be by sheet flow to perimeter areas. The discharge of the drop inlets is
unknown, but may be piped to the rear (north) of the site toward a low area adjacent to an existing stream.
The building roof is apparently largely flat (except for sheds at the rear) and roof drains that collect roof
runoff may be routed through the interior of the building and may discharge, again, to the north of the
building. To the best of our knowledge, based on limited anecdotal data, the site is not subject to routine
flooding problems.
The proposed plans show that the building and site will remain largely unchanged, with the exceptions
that new canopies are proposed over several of the entrances, and new landscaped bed(s) will line the
store fronts. In as much as the existing plaza, within the developed area, is nearly 100% impervious, we
do not believe that the new canopies will add impervious area (or runoff). Conversely, the new landscape
beds along the store fronts will add pervious area and can be used to manage runoff from the new entrance
canopies.
If you have any questions, do not hesitate to contact us at 792-2907 or me via email at

Sincerely,
JARRETT Engineers, PLLC
