Bethany,
At Riverbend Station, Lark Maintenance is expanding their footprint while the existing station is in a state of demolition.
As a result of this, topography has slightly altered within the existing drainage areas of four outfalls (NCS000549).
These outfalls are SWO02, SWO03, SWO06 and SW010. Although the drainage changes are minimal, I am planning to
update the Riverbend SPPP. See table below for changes and attached map for the updated drainage areas.

The location of these outfalls are on the other aside of the intake canal, therefore there are no reports of basin seeps in
this area.
I have also included previous guidance I received from Ken Pickle on updating the SPP at Marshall.
Thanks for your help and let me know if you have any questions or concerns,
Brad
