This document is a detailed engineering design plan for a proposed culvert replacement project, focusing on erosion and sedimentation control. The technical drawing includes a comprehensive plan view, profile view, and cross-sectional diagrams of proposed infrastructure modifications. Key elements include a proposed cast-in-place concrete junction box, existing and proposed concrete outlet structures, and corrugated metal pipe (C.M.P.) arches at various stations (STA. 0+00 to 1+16 and 5+62 to 7+23). The design specifies smooth-lined aluminum culvert sections and details temporary storage/filter areas. The general sequence of construction involves temporary stream diversion, installation of concrete boxes and pipe arches, grading, and stabilization of disturbed areas, with precise elevation and dimensional specifications provided across multiple technical views.
