ADDITIONAL PROJECT INFORMATION
BRIDGE AND SEDIMENT REMOVAL AT REVOLUTION MILL
The following pages include some cross-sections showing proposed grading, a profile of the stream
channel through this area exported from the FEMA flood model (thalweg & 2/10 year flood elevations),
and some photos of the area. A proposed planting plan is included as an appendix.
For the cross-sections, the "bench area" is on —2% slope towards the stream and the slopes are —3:1.
The locations are shown on the aerial figure on page 4.

ground may be sawed off and some grading done to smooth out the area before replanting.

This area is significantly higher than the right overbank under the bridge that will be removed, so some
excavation for a floodplain bench is proposed through this area.

These are photos sent earlier to David Bailey (in a query before filing PCN). Below is the "Grassy bridge"
slated for removal and replacement — viewed from downstream side. The tree was later cut at ground
level because it was a hindrance to visibility for vehicles at Revolution Mill pulling out onto Yanceyville.
"Grassy bridge" from upstream side. There are concrete retaining walls at each end of the bridge that
will remain in place. The owners would also like to remove some of the debris/rock/sediment upstream
and downstream of the bridge to some extent.

Right bank area — looking downstream from the "grassy bridge" to Yanceyville Street. Owners would
like to clean up right bank and grade a floodplain bench between grassy bridge and Yanceyville Street.

Looking upstream from "grassy bridge" where an old vehicle access ramp (with numerous piers) was
replaced with an open -span pedestrian access. Owners would like to remove accumulated sediments in
these areas and grade a floodplain bench. (This is a secondary flow area. The stream goes under the
building to the right in the photo.)

These photos were all taken in April 2018 — in order from upstream areas to downstream areas.
This photo is taking facing upstream towards the Mill House building. Sawing off some of these posts at
stream bed level may be done to improve the aesthetics. The potential grading is limited by the
steepness of the upper bank, but to the extent there is an adequate retaining wall at the top of the
bank, it may be possible to grade a small bench area as shown on the cross-section.
This is the area under the former dock. Again, it is too steep for to allow for much excavation of
sediments, but the area will be smoothed out and replanted.

Another shot of the area under the former dock. Some of the former piers need to be sawed off at a
lower elevation in order to smooth out the bank in this area.
Area downstream of the dock and upstream and under the grassy bridge slated for removal, which
needs to be more evenly graded and also cleaned upThe area proposed for a floodplain bench is
downstream of the grassy bridge where you can see that the bank comes up.

A —20 -foot floodplain bench is proposed for this area, partly dependent on how far down it is
structurally acceptable to excavate at the retaining wall.
