General Project Narrative: The purpose of the project is to replace Bridge No. 63 on SR 1104 over Hadnot Creek in Carteret County. The existing bridge is 52.0 feet long. The replacement structure will
(Description of Minimization of Water be a 1@ 55' and 1@ 30' long bridge, providing a 27.83' clear deck width. The roadway grade of the new structure will be approximately the same as the existing structure.
Quality Impacts) There will be no direct discharge into the stream (deck drains on the bridge). The existing bridge had two bents in the stream, while the proposed bridge only has one bent in
the stream bank. All existing stormwater drainage patterns were maintained on the project to the fullest extent. The storm drainage system picking up the bridge deck drainage
will be outleted outside of the CAMA Buffer onto a dissipator pad, in a proposed ditch on the southwest quadrant of the bridge. The existing ditches on the northwest, southwest,
and southeast quadrants were tied into prposed ditches due to widening of the proposed roadway footprint filling in the existing ditches. All three of these ditches were ditched
to the stream, just as the existing ditches were.

Additional Comments
The combined total length of the ditch from 13+00 to 14+50 -L- Lt is sufficient. The ditch was separted to specify different logitudinal slopes. CAMA buffers are in effect, not riparian buffers.
