Dear John & Todd:
OWASA is planning to expand the Mason Farm WWTP on Morgan Creek in southeastern Chapel Hill. Morgan Creek, which
historically formed a meander around the west, north, and east sides of the WWTP, has been forming a new bypass channel
south of the WWTP. The bypass, which now carries most of the stream's low flow, is 1/3 the length of the old channel, and
therefore 3 times as steep in gradient. As the bypass continues to downcut, Morgan Creek will lose about 2,600 feet (3,900 feet
old channel length minus 1,300 feet new bypass channel length), and the WWTP is losing much-needed land for new treatment
facilities.
OWASA has contracted us, with the assistance of Skelly & Loy, to investigate options for stabilizing Morgan Creek, and
possibly filling in the bypass channel, thus restoring the original flow pattern. We're scheduling a site visit and meeting with
OWASA at the WWTP for sometime between May 14 and May 24. We'd like representatives from COE and DWQ to attend,
to see the situation and discuss design and permitting options. I'll send you each a location map, topo map of the WWTP area,
and our wetland delineation map of the bypass area.
Please contact me to select a date and time when you'd be available to meet for 1.0 to 1.5 hr in Chapel Hill.
