The interior walls oithe culverts will be lined with countersunk class II riprap to create artifcial floodptains and rnaintain char►nel width gaing ihrough the structures. The short sta�eatn relocation near the downstream portion of the bridge #46 culvert has been lined with riprap for sta.bility reasons. Construction of the new culverts will require temporary dewateri�g via dikes and jump pipes. T'he details are spelled out in the constraction sequences in the pIan sheets. Once the new structures are in place, the impervious dikes and temporary pipes wili be rernoved and preconstruction streambed eleva#ions wrli be restored. Construction of this project will reqnire impacts to waters vf the United States in the New River Basin. The e�sting bridges cross Grassy Creek (Ciass: WS-N -�)_ The project fs located within a trou# waiershed_ This project does not c�-ain to desigiated critical �abitat %r the elk toe mussel. This project was reviewed for the presence of threatened and endangered species in the field ar�d I have also included � query of the NCNIIP database. Based on the project area mapped with my request, the database search indicates that there are no records of any federally Iisted threatened or endangered species, itnportant nat�ral communities, naturai areas, or conservation/managed areas within the proposed project boundary.
