My apologies!! I got this from the engineer last week and forgot to send it to you. Let me know if you need
anything else... I do know that the City of Monroe has not issued the SW yet (they are waiting on driveway
permits from DOT and a couple of other items before they issue).
Thanks!!

Sent this originally on 5/29. Question about SW. Just one BMP, appears to be on plan. Can
you confirm/clarify. That would handle the entire development?
Thanks

Where's the SW ... doesn't look there is room for typical BMPs. They aren't shown on plan,
