Miles Barrel Width/Diameter (ft): 9' Surface Water Body: (1)Charles Creek Barrel Height (ft): 6' Culvert T e: Reinforced Concrete Box Culvert Culvert Length (ft) 35 Avoidance and Minimization Efforts: The length of the culvert was minimized to the maximum extent possible given the roadway geometry and skew of stream. (Bridge to Culvert) Stream Slope Fish and/or Aquatic Life Passage Existing Average Stream Slope (%): 2.41 % Existing Low Flow Channel Dimensions 7.9' - 8.4' Proposed Culvert Slope (%): 2.43 % in the Stream: Culvert Burial Proposed Culvert Burial Depth (ft): 1 Existing Streambed Material: Rocky with some silty sand material Proposed Low Flow Dimensions 8' Through the Culvert: Proposed Sills/Baffles: A low flow sill is created in the right barrel. A high flow sill is created in the left side barrel. This low flow Existing Low Flow Velocities in the sill is 0.5' lower than the high flow sill and baffles. Stream (ft/s): 2'3 Proposed Low Flow Velocities Through the Culvert (ft/s): 1.4 (US) 2.0 (DS) Alternating Low Flow Sills/Baffles: The low flow sills/baffles are placed in the right barrel. The high flow sills/baffles are placed in the left barrel. The sills/baffles are spaced Culvert/Stream Alignment Stream Patterns Upstream and The stream is relatively shallow in normal flow conditions which may prevent some fish passage during normal flow. The stream discharges into Downstream of the Culvert that Could Hamby Creek just downatream of the culvert outlet. This could create some bank stability along the outlet of the culvert. Affect Fish Passage and Bank Stability: Bed Forms Impacted by Culvert (riffles, None pools, glides, etc.): Low Flow Floodplain Bench Required? Yes A low flow channel of 9 feet is provided. The low flow channel width was based upon the width of the exisitng low flow channel at (provide justification) the proposed culvert location. Bends at Inlet/Outlet? Yes The stream is straight at the inlet of the culvert. The outlet is near the confluence of Hamby Creek. (describe culvert alignment with stream) Stream Realignment Necessary? (provide No The culvert is aligned with the stream therefore no stream realignment is required. justification) Bank Stabilization: Riprap bank stabilization is required at the headwalls of the inlet and outlet of the culvert. Outlet Velocities Natural Stream Channel 2-yr Velocity (ft/s : 6.8 Natural Stream Channel 70-yr Velocity (ft/s): 8.7 Proposed Culvert 2- r Outlet Velocity (ft/s): 4.8 Proposed Culvert 70-yr Outlet Velocity (ft/s): 5.9 Roadwa Geometric Considerations Evaluate/Describe Roadwa Geometric Constraints: None, the roadway is fairly straight across the culvert.
