ADDITIONAL INFORMATION

Please use this space to provide any additional information about the
drainage area(s):
Individual drainage areas do not sum to total site drainage area. Pervious
bypass areas will consist of lawn, so uncaptured runoff (if any) will be
minimal. Impervious bypass areas drain to existing structures which are to
remain, so there will be no increase in uncaptured runoff resulting from
