Document Description
The proposed project consists of improvements to SR-91 in Orange County by adding one general-purpose lane on SR-91 eastbound from the SR-91/SR-55 (PM 9.1) separation to east of the Weir Canyon Road on-ramp (PM 15.0), and on SR-91 westbound from west of the SR-91/SR-241 separation (PM 15.1) to the SR-90/SR-91 separation (Imperial Highway Undercrossing(PM11.1)). The project would relive congestion and improve operational efficiency on SR-91 between SR-55 and west of SR-241. The total length of the project is 6.0 miles. The project will extend existing culverts associated with the roadway widening. A total of 4,400 cubic yards of roadway backfill will be used to fill existing earthen, asphalt and concrete ditches and replace them with .0575 acres of bioswale and/or bioswale and pipe combinations. The path of flow will not change. Measures have been included in Streambed Alteration Agreement 1600-2010-0194-R5, issued by the Department of Fish and Game (DFG), to avoid these potential impacts.
