Subject: Rockingham Grocery stormwater plans #15-0615

Today, I received four copies of the drawings for the stormwater plan for the Rockingham Grocery project. The plans did
not include an updated “Wet Detention Basin Design” calculations sheet. We received a copy of the calculations that
was dated Dec 18, 2015 but it does not seem to have been updated to reflect the drawings. In just a quick look, I did
th
notice the orifice drawings showed a 1.5” draw-down orifice and the December 18 Wet Detention Basin Design sheets
showed a 1.0” draw-down orifice. Please send me copy of the engineering calculations for the wet detention basin that
you intend to apply to the drawings that I received today. You can email them to me at [e-mail].
Thanks
