1. Silt fencing on outside of channel from about STA 9+00 to about STA 13+00 will likely provide
little sediment control. Use check dams here or show silt fencing between channel and
disturbance.

has been removed,and replaced with check dams along the channel.
2. Please provide date and source of topographic information.
RESPONSE: General Note 2 on plan sheet 3 was updated to include the date(November 9,
2011) and source of the topographic information(Rinker Design Associates)
3. Provide explanation of and for darkly hatched areas seen throughout plans.
RESPONSE: The hatched areas represent gravel surfaces. The line weight has been
modified to make it appear less pronounced.The line weight for these areas was changed in
the updated plan sheets.
4. Show staging/stockpile area(s)on plans.
RESPONSE: In accordance with direction provided from Glenn Brooks to Alex Morrison,
the storage and staging areas were not shown on the plans,but rather expressed that the
staging and storage area would be moving with the trench since it is a linear construction
project.Section 6.6 of the SWPPP report contains this information.
