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.
