Hi Louis
Here is correspondence on test pits and storm drainage modifications between civil engineer, Dave Valeta and Doug MacDonald. I have a 1:00
phone call with civil on another project and will ask him if he is squared away with Doug on modifications to the subsurface drainage. As I
understand it the test pits were a precondition on foundation permit. I think the ball is in Doug's court right now, will let you know what the civil tells
me.

Hi David,
We performed soil testing in the area of the proposed infiltration system for ServiceNet on Monday. As you’ll
see on the attached plan, we encountered some undesirable soils at the far eastern edge of the originally
proposed system, but soils to the west were consistent with the previous soil data that we used as a basis for our
design. To address this issue, we have made the proposed system shorter and wider to maintain the provided
storage volume while staying clear of the less pervious soils. We also encountered mottling slightly higher than
we originally anticipated, so we raised the bottom of the system about 0.4’ to ensure we had the 2-feet of
separation. I’ve attached the HydroCAD report for the revised proposed conditions. Peak Flows, Recharge
Volume, etc. remain virtually unchanged from the previous report.
Please review and let me know if you have any questions/concerns, and what you’ll need us to submit for
revised plans and calculations.
