On this. date, Kent Laza .and myself met with North Barden and Alan Gibbs of MDG to discuss
the problems of determining an accurate floodway within the floodplain of Carter's Creek at this
location.
We reached the .agreement that due to the magnitude of the flooding of Carter's Creek over
Highway 30. {Harvey Road) and the inadequacy of the existing drainage improvements under both
Harvey Road and the .Access Alley to Sam's, that determining an accurate floodway for the
Carters Grove .tributary within' the Carter's Creek Fooodplain was impractical, if not impossible.
Therefore the requirement to show the floodway on this project has been waived.
We verified that the potential .increase in storm runoff. generated by the site improvements would
be controlled by the onsite detention facility to predevelopment levels or less, so no increase in
flooding downstream wih occur.
The fill for the parking area north of the channel will be allowed without a variance procedure
because of the impossibility of determining the actual location of the floodplain. The channel itself
will be improved to handle the runoff velocities at the bend in the creek.
