Surface Water Body: 1 Jordan Branch Barrel Hei ht ft: 6'-8"
Culvert T e: Aluminum box culvert Culvert Len th ft 54'
Avoidance and Minimization Efforts: Culvert is designed to minimize stream impact by being the minimum length to provide an adequate roadway cross section and by placement at or
(Bridge to Culvert) near natural streeam grade. Culvert will include sills and low flow channel to closely match existing stream bed
Stream Slope Fish and/or Aquatic Life Passa e
Existing Average Stream Slope %): 1.80 % Existing Low Flow Channel Dimensions The existing low flow channel is approiximately
Proposed Culvert Slope (%): 1.00 % in the Stream: 6 feet wide
Culvert Burial
Proposed Cubert Burial Depth (ft): 2
Existing Streambed Material: Cobbles and gravel with some coarse sand Proposed Low Flow Dimensions The low flow channel through the culvert will be

Stream Patterns Upstream and Downstream The stream is of uniform slope immediately up and down stream of the culvert with no sharp bends.
of the Culvert that Could Affect Fish
Passage and Bank Stability:
Bed Forms Impacted by Culvert (riffles, Stream is generally shallow and free flowing through project area; no signifigant bed forms will be impacted
pools, glides, etc.):
Low Flow Floodplain Bench Required? Yes Low flow channel was provided to match existing stream channel
(provide justification)
Sharp Bends at Inlet/Outlet? No
(describe culvert alignment with stream)
Stream Realignment Necessary? (provide No
justification)
Bank Stabilization: Streambanks to be stabilized with Class II rip rap for approximately 30 feet up and down sterem from culvert
Outlet Velocities
Natural Stream Channel 2-yr Velocity (ft/s): 5.1 Q5 Natural Stream Channel 10-yr Velocity (ft/s): 6.6
Proposed Culvert 2-yr Outlet Velocity (ft/s): 4.7 Q5) Proposed Culvert 10-yr Outlet Velocity (ft/s): 7
Roadwa Geometric Considerations
Evaluate/Describe Roadway Geometric Constraints:
The proposed culvert has been designed to generally maintain the roadway alignment with slight improvement to the cross-section.
