Hello John,
I took a quick look at this project.Glenn's original e-mail/direction to me dated 7/28/15 states in his 8th sentence, "I have also
included the other lane of the road in the overall load computation, but not in the load to the facilities." In this e-mail he is stating
we need to include Carroll Creek Road in the project's overall water quality calculations,which I feel triggers the use of the VRRM
ReDevelopment spreadsheet.
If we continue to use this spreadsheet,and update it to list an approximate limits of disturbance of 9 acres,then the required
removal rate becomes 3.05 lbs/yr and our current plan removes 2.34 lbs/yr(a slight shortfall).
Please let me know what your thoughts are on this once you've had a chance to contemplate it.
Thanks,
Graham
P.S. I believe you have access to Glenn's e-mail from my prior correspondence Friday afternoon, but I can forward it to you if not.
Also,Glenn's last sentence in the 7/28/15 is no longer applicable with the amended/consolidated facility.

Good afternoon John,
Thanks for your phone call a few minutes ago. I'll try to answer your questions ahead of our 2:30 phone call,and if you still need to
talk we can.
1. The assumed average lot's impervious footprint in my October 15,2015 calculations packet is 6,000sf. I believe this is a
high, but representative,footprint for the development.
2. With respect to Glenn's archived e-mail in your project file, attached are the follow up e-mails between Glenn and I in this
string of correspondences.
