These culverts will be single barreled culverts and will not have high and low flow barrels. Stabilization of the culvert entrance and exit will be part of the design. I have attached a plan view layout of the culvert configuration for the Lawndale interchange. The plan is to backfill the culverts with alluvial sediments that are obtained during the excavation of the proposed culverts. I am checking on the permit modification submittal date and will send that as soon as I know. Please let me know if you have additional questions. Regards, Matt Matthew (MattJ Lauffer, PE, CPM Asst.

The proposed sills and baffles appear to be consistent with DOT's guidance on the subject. Will these culverts possess high flow barrels and flood plain benches, and if so, what type of material will be used for backfill (if they are planned to be backfilled)? Do you have a time estimate for when a permit modification will be submitted for the D section? I have copied Dave Bailey with the Corps for his review and comments. Dave B., These are the culvert data of which we spoke yesterday. Dave W Dave Wanucha NC DENR Winston Salem Region Office NC Division of Water Resources Transportation Permitting Unit 450 W.

The following is a summary of the structures and proposed configurations: Culvert ID Culvert 1 Length (Feet) Size Slope Burial Sills 1430 8' X 8' 1.04% 1' Yes Culvert 2A 363 11'X9' 1.86% 1' Culvert 2B 712 11'X9' 0.50% 1' Culvert 3 1214 11'X9' 0.59% 1' Culvert 4 335 7'X8' 2.07% 1' Yes Yes Yes Yes Baffles No Yes (25 foot Centers) No No Yes (20 foot Centers Approximate Width of Stream 5-6 ' Confluence of two streams - 4-5' and 5-6' Confluence of two streams - 4-5' and 5-6' 10' 6-7' You will notice that the lengths of the culverts are long and that sills are used on all culverts and all culverts will be buried a foot. Baffles will be placed on Culvert 2A and Culvert 4 where slopes are near 2%. Baffles will be placed across the entire box with no additional reduction in stream width. Stream pictures are below for reference. Please let me know if you concur with the proposal or would like to discuss further. My phone number is below.
