Do you know the name of the staff member you would like to request a meeting with?
Please give a brief project description below and include location information. *

The City of Statesville is proposing to repair and extend an existing
culvert that runs under Columbia Street in the City of Statesville.
Statesville is proposing to flatten the near vertical embankment
slopes to an approximately 3:1 slope immediately north and south of
Columbia Street, extend the existing culvert by approximately 28 LF
downstream and by 20 linear feet upstream, and install inlet
protection against ongoing scour upstream. Repairs on the
downstream end of the culvert would include installing a drop
manhole structure at the existing culvert and extending the culvert
downstream at grade. Alluvial soils related to ongoing erosion would
be removed from the construction area as necessary and the culvert
end -wall would be repaired or replaced. The preliminary design set
has been attached to this Pre -Filing Meeting Request.
The 60-inch culvert proposed for repair and extension conveys
surface water within an unnamed tributary that runs under Columbia
Street to Third Creek located downstream to the south. The City of
Statesville anticipates on submitting a pre -construction notification to
the U.S. Army Corps District Engineer and NC DEQ Division of Water
Resources prior to commencing with culvert repair.
Please give a couple of dates you are available for a meeting.
