Please use this space to provide any additional information about the
drainage area(s):
The entire site BUA is based on the entire Limit of Disturbance (LOD) due to
being located on a military installation, no lot lines or parcels. The LOD is =
6.5 acres. The actual drainage areas to the SCM (also summarized in the
calculations package) is 5.05 acres.
