Line 2000 Span Coverage Corona, Riverside County
Document Type
NOE - Notice of Exemption
Document Description
The intent of the project is to cover an exposed 36-foot high pressure gas pipeline span with native fill to prevent damage to the unprotected pipe from rocks and debris, and to reduce the need for continued vegetation management. At present, the span sits within the low point of a stream channel where it has become nearly obscured by woody vegetation and where regular contact with moist soil subjects the span to an increased change of rust and corrosion. A contract crew of four will use an excavator to first remove riparian vegetation from either side of the span, then cover the line with 178 cu yds (60 ft. long x 20 ft. wide x average 4 ft deep) of clean, native fill stabilized with a riprap berm of 36 cu yds (60 ft long x 4 ft deep x 4 ft wide) to prevent the loose material from washing downstream.
