Section VII. Avoidance and Minimization
Crossing C2
Culvert replacement was used to bring culvert invert nearer to existing stream invert.
Relocated stream channel follows foot of embankment (toe of slope) in order to tie back
in to the existing stream channel at the earliest possible point.
Crossing C7
Culvert replacement was used to bring culvert invert nearer to existing stream invert.
Use of plunge pool to dissipate energy to existing incised stream channel. Relocated
stream channel follows toe of slope to allow efficient tie-in to existing stream channel.
Crossing C8
Impacts to this crossing were avoided. -
Crossing C9
Culvert replacement was used to bring culvert invert nearer to existing stream invert.
Use of plunge pool to dissipate energy to existing incised stream channel. Relocated
stream channel follows toe of slope to allow efficient tie-in to existing stream channel.
New pipe was placed to minimize cut/fill impacts to wetland.
Crossing C10
Impacts to this cros:;ing were avoided.
Crossing C11
Impacts to this crossing were avoided.
Crossing C12
Culvert was extended instead of being replaced, allowing work on only one side of the
rail bed. No stream relocation was necessary. Excavation is proposed only for footprint
of new track.
Crossing C13
Culvert was extended instead of being replaced, allowing work on only one side of the
rail bed. Stream relocation is necessary, but will follow toe of slope to minimize length of
stream relocation. Excavation or fill is proposed only for footprint of new track.
Crossing C16
Culvert replacement was used to bring culvert invert nearer to existing stream invert.
Relocated stream c~~annel follows foot of embankment (toe of slope) in order to tie back
in to the existing stream channel at the closest possible point.
Crossing C17
Impacts to this crossing were avoided.
Crossing C18
Culvert replacement was used to bring culvert invert nearer to existing stream invert.
Use of plunge pool to dissipate energy to existing incised stream channel. Relocated
stream channel follows toe of slope to allow efficient tie-in to existing stream channel.
New pipe was placed to minimize cut/fill impacts to wetland.

Section VII. Avoidance and Minimization
Existing above-grade pipes to be filled. Culvert was extended instead of being replaced,
allowing work on only one side of the rail bed. No stream relocation was necessary.
Crossing C20
Culvert replacement was used to bring culvert invert nearer to existing stream invert.
Use of plunge pool to dissipate energy to existing incised stream channel. Relocated
stream channel follows toe of slope to allow efficient tie-in to existing stream channel.
New pipe was placed to minimize cut/fill impacts to wetland.
Crossing C22
Culvert replacement was used to bring culvert invert nearer to existing stream invert.
Use of plunge pool to dissipate energy to existing incised stream channel. Relocated
stream channel follows toe of slope to allow efficient tie-in to existing stream channel.
New pipe was placed to minimize cut/fill impacts to wetland.
