CAUTION:nd all suspicious
Hi, Folks,
A bit of change in the construction plans: the engineering team was able to reduce the permanent stream
crossings from 5 to 3, and replace all planned double-barrel culverts with single -barrel culverts. Attached are
construction plans that show locations of culverts, crane pads, and erosion control fencing, as well as the
hydroCAD and culvert design plans. I updated the PCN Form to reflect the new stream impact calculations and
included a revised waters table with the same. Please also note that vegetation clearing within stream buffers
(25' on each side of every water) will be done by hand to avoid soil compaction by heavy machinery.
Amanda, you asked for acreage of forested area within iso feet of impacted streams that will be changed to
early successional community. That number is approximately 1.3 acres. Please note that that acreage includes
a 25' buffer on each side of S3 which will, as much as possible, be left as a rhododendron -heavy shrub
community. Note in the table that the plan is to cut tall trees and leave vegetation 15' and under outside of the
access road corridor for the trout buffer. That area comes to approximately o.o6 acre.
Please let us know as soon as possible if you have further questions or concerns, or if you have trouble opening
this file!

Designs were modified to avoid placing structures in waters of the US. Crossings over waters of the US attempted, as much as possible, to cross at
perpendicular angles. Stream buffers (25' on each side of streams) will be maintained by non -mechanized clearing. Existing roadways were utilized
for access.
