SUBJECT: Barbara Bailey Drainage Complaint / 232 Plantation Drive
DATE: July 24, 1992
This memo is being written as a follow-up to my July 21, 1992 letter to Mr. Waymon Levell
thatimposed a 48 hour stop work order notice on the Wynnpage Addition if the project was not brought
into compliance with Erosion and Sedimentation Control Code Ordinance #91514. The four items in
particular that needed to be corrected were:
1) Removal of debris from the channel.
2) Scrapping siltation from the alley.
3) Installation of some type of silt fence or erosion control barrier.
4) Removal of the siltation from the downstream channel.
I visited the job site with Mr. Randy Lockhart representing the developer at 6:30 p.m. on July 23, 1992.
Mr. Lockhart and myself walked the reach of the concrete channel behind the houses on Plantation Dr.
By walking the concrete channel, it was noted that the majority of the water standing in the channel
was caused by several side slope failures, most notedly, a side slope failure at approximately 224
Plantation Dr. There were several other failures along the reach of the channel also. Mr. Lockhart's
people spent most of the day on July 23, 1992 removing siltation from the channel. After walking
the channel and seeing the side slope failures that were in no way connected to Wynnpage, Mr.
Lockhart and myself ascertained the limits of the actual siltation from the Wynnpage Addition. I made
a visual inspection of the channel again this morning at approximately 7:00 a.m. and the majority of
the siltation from the main channel has been removed. However, there is still approximately 20 to 30
foot of a minor channel running east/west behind Wynnpage that still has some siltation. It is my
understanding that they will be removing that siltation this morning.
Even though the majority of the siltation caused by the Wynnpage Development has been removed,
water still stands in the concrete portion of the channel. To allow the water to flow freely through this
channel, the side slope channel failures will need to be repaired. From previous conversations with the
Public Works Department, it is my understanding that the City assumes the responsibility for the
maintenance of the concrete portion of the channel, but not the maintenance of the earthen portion.
It is quite possible that City crews will need to remove the side slope failures out of the concrete
channel to allow the flow of the water. I spoke with Steve Goram today and he stated that the work
to remove the side slope failures will begin on July 27,1992.

The status of the other four items is as follows: the debris has been removed from the channel, the
siltation has been removed from the alley, a hay barrier has been installed in this vicinity of the alley
to keep the siltation from flowing into the drainage system, and there is just a minor portion of siltation
still to be removed from the downstream channel that was caused by the Wynnpage Development. As
previously stated, there will still be standing water in the channel until the side slope failures further
on down this channel have been removed.
As you are aware, effective 8:00 a.m. on July 24, 1992 this project has been shut down. I told Mr.
Lockhart to contact this office immediately upon completion of the remaining removal of the siltation
so that an inspection can be made by City forces to determine if the project can be released for further
inspections and permits.
I would be happy to discuss this with you at your convenience.
