This bridge replacement and the associated roadway improvements have been designed in a manner that minimizes the increase in impervious surface area. One of the Quality Impacts) two culvert barrels will have a sill that is 0.5' higher than the other barrel, causing the stream to flow through only one barrel under normal flow conditions. The northeast, northwest, and southwest quadrants of the project contain Special Cut Ditches that convey water from roadside ditches to the stream. Rip rap lining is specified where necessary to provide erosion protection.

A floodplain bench and 1.5' sills in the high (Bridge to Culvert) flow barrel of the culvert promote low flow in one barrel only, maintaining the existing low flow channel dimensions and velocities as closely as possible. The culvert approximates the existing bed slope and provides a smooth transition from upstream to downstream. The proposed culvert is better aligned with the stream and provides less abrupt bends at the inlet and outlet compared to the existing bridge.

Passage and Bank Stability: Bed Forms Impacted by Culvert (riffles, A long riffle runs through the proposed location of the culvert. pools, glides, etc.): Low Flow Floodplain Bench Required? Yes A floodplain bench is necessary to provide the low-flow channel geometry necessary to approximate the existing stream as well as (provide justification) adequately pass high flow events without increasing water surface elevations upstream of the culvert. Sharp Bends at Inlet/Outlet? Yes Bends are present at the inlet and outlet of the proposed culvert due to the natural alignment of the existing stream. (describe culvert alignment with stream) Stream Realignment Necessary? (provide Yes The propsed culvert is skewed to the road to provide less abrupt inlet and outlet bends than the existing bridge allows. This should justification) reduce the threat of bank degradation. Bank Stabilization: Class I rip rap has been specified for the banks upstream and downstream of the proposed culvert to provide bank stabilization. Outlet Velocities Natural Stream Channel 2-yr Velocity (ft/s): 3.5 Natural Stream Channel 10-yr Velocity (ft/s): 3.9 Proposed Culvert 2-yr Outlet Velocity (ft/s): 3.5 Proposed Culvert 10-yr Outlet Velocity (ft/s): 3.8 Roadway Geometric Considerations Evaluate/Describe Roadway Geometric Constraints: The general alignment of the stream approaches and leaves the roadway crossing on an extreme skew. It would be impracticable to install a culvert along this alignment as the skew would be very large and straightening the stream too much may be detrimental to its stability. � � + �' a� 3 � a �, � oT N=� � _� N�- NNE 00.�� See Sheet 9-A For Index of Sheets See Sheet 1-B For Conventlonol Symbols GRAPHIC SCALES 20 10 0 20 40 PLANS 20 10 0 20 40 PROFILE (HORIZONTAL) 4 2 0 4 8 DESIGN DATA ADT 2010 = 590 DHV = % � _ % T = 0 % * V = 40 MPH FUNC CLASS = RURAL LOCAL �� 1L � �� `�/�� Y �� 1LJ�1L�� V'V' � Il � B U1�COMBE CO U1�lTY LOCATI011I: BRIDGE 11r0.100291 OVER UNNAMED BRANCH OF LITTLE POLE CREEK 011t SR 1222 TYPE OF WORK: GRADI11lG, DRAl11tAGE, A111D PAVI11lG WETLAND AND SURFACE WATER IMPACTS PERMIT —L— STA I4+30.00 E111D PROJECT 17BP.13.R.25 o�� O�S� P�� P��l Q�� I� � �O `�� < � `�� y � � � �� \ �� O �� _ � B,p��, S -_.
