Document Description
CDFW is issuing an Agreement regarding the proposed Streambed Alteration 1600-2014-0001-06 to the California Department of Transportation (Applicant), for the State Route (SR-58) Hinkley Expressway Project (Project). The Project includes SR-58 realignment and widening from a two-lane roadway to a four-lane expressway/freeway from PM 21.8 west of Hidden River Rd. near Hinkley and eastward to PM 31.1 0.775 miles east of Lenwood Rd. The Project will impact several ephemeral streams and playas, the majority of which are located west of Hinkley road. All streams and playas located in the Project area are ephemeral and are considered CDFW jurisdictional waters. Currently the Project area supports ephermal stream and V-ditches that direct water under or over the existing SR-58. These V-ditches and streams will be redirected and re-incorporated into the new design to the SR-58 widening. The Project also, includes the construction of facilities for drainages via culvert and detention basins west of Hinkley road. Drainage facilities will be in the form of two detention/retention basins and approximately 34 new box culverts (with minimum dimension of three by five feet) 7 of which would function as wildlife crossings for Desert tortoises. The Project is incorporating desert tortoise fencing, and would design undercrossing in such a ways to accommodate the desert tortoise movement. Vegetation surrounding the ephemeral streams general consists of creosote bush scrub or atriplex scrub. The project will permanently impact 2.176 acres of CDFW jurisdictional waters. The impacts were determined in the field according to the apparent limits of flooding, flood plain indicators such as debris lines, topographic changes and sediment deposits. The impacts shall be mitigated for at a ratio of 3:1 for a total required mitigation of 6.628 acres. The purchased land should have comparable ephemeral washes along with desert tortoise and Mohave ground squirrel habitat which includes creosote bush scrub and/or atriplex scrub vegetation types.
