<p class="MsoNormal"><span style="color:#1F497D">Hello,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I’ll speak to a couple of points<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">There may be ground water impacts depending on what buried pipes are in the area and the depth of the SWP.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Where there are large pipes +- 950 cm buried at depths on say 4m +, typically in my understanding the bedding of the granular pipe bedding can be a conduit for the accumulation of ground water moving it down
the pipe bedding.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Yes there can be water table impacts and knowing the hydrology of the area and the soil bore hole test results can help form the optimum location of the SWP. Tough sell as usually it is the low point Developers
design to using gravity to deal with the storm runoff and existing in some cases natural water venues.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Run off into woods usually brings silt and other soluble chemicals as the runoff generally comes from the roads and driveways with oil, antifreeze, solvents, soap + road salt to name a few.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The silt alone is enough to smother the roots where there are breeches in the filter fabric or sediment control over the few years the construction and subsequent infrastructure is built feeding into the pond.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Hope you have sufficient funds to deal with the “unique material” accumulated at the bottom of the pond that will have to be dredged in the future as siltation occurs or have sufficient space on site to store
the “unique material.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Further as they mature the SWP become venues for something called “wildlife” that can establish in the area and when you dredge…….<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-CA" style="font-family:"Candara","sans-serif";color:#39471D">As I have been running across this issue more and more lately, I’m wondering if any of you have experience with the installation of stormwater management infrastructure
