We are in receipt of the above referenced Notice of Violation, dated April 19, 2022,
which involved overflows at two locations occurring on March 17, 2022.
The City's rain gauge at Cool Springs Road water tank measured 1.97 inches of rainfall
on March 16 and 0.49 inches of rainfall on March 17.
Below is a discussion of the actions being taken to address these occurrences.

Incident 202200415 Patterson Creek ROW
This incident took place at the Patterson Creek lift station. It is located within 2 miles of
the Cool Springs Road rain gauge.
This is the first incident at this location and there has been very little growth in this area.
In the next fiscal year, flow monitors will be installed in the gravity sewer lines supplying
the lift station to monitor and determine where the flows may be originating. The City
will also look into the installation of a flowmeter to monitor pumping rate at the station
itself. This will provide another means to monitor the performance of the station.
Incident 202200416 2002 Shoreline
This incident took place at manhole number 1452. It is located within 1 mile of the Cool
Springs Road rain gauge.
This is upstream of manhole 1450, where we have recorded previous issues. At the time
of the incident a flow monitor was installed in manhole 1450. Some surcharging was
evident so the City will look into installing additional flow monitors to determine the
source.
Should you have any questions, please feel free to contact me at any time.
Sincerely,
,-DocuSigned by:
