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.
