Karen,
These 2 greenways connectors just span from one side of the buffer over the creek to the other side of the buffer.
There is very little that can be done to create diffuse flow in areas like this—usually there is a little bit of runoff from
greenway(or road)crossings that we let go. My recommendation is to approve it if everything else looks to be in order.
A condition is attached.
Thanks,
A

1. Diffuse Flow Approval by the DWQ for Greenways
All stormwater shall be directed and maintained as diffuse flow at non-erosive velocities through the
protected stream buffers such that it will not re-concentrate before discharging into a stream. If this
is not possible, it may be necessary to provide an engineered level spreader or stormwater facilities
to remove nitrogen and phosphorus priori to discharge. If deemed necessary,these facilities will
require additional approval from the Division of Water Quality.
