Document Description
The Project proposes improvements to the Rialto Channel, which extends approximately 2.97 miles between Willow Avenue and Etiwanda Avenue in the City of Rialto. The Proposed Project will involve grading activities such as excavation and fill, construction of a reinforced concrete rectangular and trapezoidal channel, and the replacement of undersized reinforced concrete box (RCB) culverts at multiple street crossings. The improvements are designed to convey flows associated with a 100-year storm event. The Proposed Project will require relocation of several existing utilities, including waterlines, gas lines, fiber optic and cable television (CATV) lines, Southern California Edison (SCE) duct banks, and sewer lines. Excess soil and rock will be exported from the site; however, no vegetation or tree removal is proposed. Final surfaces will consist of reinforced concrete for the channel and asphalt concrete for the access roads.
