Andrew,
My apologies for sending this later than expected, but our response to your request for additional information is provide
below.
1. Please provide additional information regarding sediment removal from the existing culverts and include how
much sediment will be removed from the culverts and how much sediment will be left in the culvert. Please
demonstrate that, in accordance with Condition 11.11. of GC 4134, in areas where multiple barrels are present,
widening of the stream will be avoided to allow for aquatic life movement during low flow. If present, it may be
advantageous to leave a floodplain bench within one barrel to ensure continuity of water movement during low
flow. [15A NCAC 02H .0506(b)]
a. Both existing culverts are bottomless. Sheet 3.01 of the Construction Plans has been revised to ensure
that the northern culvert remains the low flow culvert and will be the only culvert to be cleaned out
of excessive sediment buildup above the channel bed. The elevation of sediment in the southern
culvert will continue to be 6 inches higher to accommodate excess flow as shown on the attached plan
sheet.
Please let me know if you have any questions about the information provided.
Thanks,
Jennifer
