ADDRESSES: The virtual meeting link was made available on the project website at www.metro.net/
405expresslanes. A recording of one of the public scoping meetings, in English and in Spanish, is available for viewing via the interactive StoryMap on the project website.
FOR FURTHER INFORMATION CONTACT: For Caltrans, contact Ronald Kosinski, Deputy District Director, Division of Environmental Planning, Caltrans District 7, 100 S Main Street, MS 16A, Los Angeles, CA, 90012, 213 507
4301, or email ron.kosinski@dot.ca.gov.
For FHWA, contact David Tedrick, telephone 916 4985024, or email David.tedrick@dot.gov.
SUPPLEMENTARY INFORMATION: Effective July 1, 2007, FHWA assigned, and Caltrans assumed, environmental responsibilities for this project pursuant to 23 U.S.C. 327. Caltrans, as the assigned National Environmental Policy Act NEPA agency, will prepare a Draft EIS on a proposal for a highway improvement project in Los Angeles County, California.
The Project proposes to improve traffic conditions on Interstate 405 I
405 starting in the south at Interstate 10
I10 and terminating in the north at U.S. Highway 101 US101. The proposed Project will reduce congestion, encourage carpooling and transit, improve trip reliability, reduce degradation of the carpool and generalpurpose lanes, increase person throughput, and apply technology to help manage traffic. The range of improvements may include, but not be limited to, converting existing HOV
lanes to ExpressLanes or adding an additional Express Lane in each direction and converting existing HOV
lanes to ExpressLanes.
Currently, the following alternatives are being considered, all approximately 10 miles in length:
Alternative 1: The No-Build/No Action Alternative does not include improvements to the existing lanes along I405 between I10 and US101.
Alternative 2: Convert Existing HOV to One ExpressLane Standard

Lane and Shoulder Widths. This build alternative would convert the existing HOV lane in each direction, along I405
between I10 and US101, to an ExpressLane. The northbound and southbound directions of the freeway would be restriped within the existing footprint to accommodate one 12-foot wide ExpressLane with a 4-foot wide buffer separating the ExpressLane from the 12-foot wide general-purpose lanes.
Dynamic pricing would be deployed in the ExpressLane to ensure trip reliability and traffic flow. Installation of toll and communication infrastructure and modification/
installation of overhead signs would be required. Alternative 2 proposes to widen the freeway, where necessary, to accommodate an additional weave lane at ExpressLane ingress/egress locations and maintain stopping sight distance at curves. Non-standard inside shoulders would be maintained in a few locations where constraints exist, and standard 10-foot outside shoulders would be provided where possible. Retaining walls would be provided where required to minimize and avoid right-ofway ROW acquisition. Other improvements include construction of retaining walls and sound walls, utility improvements, and drainage improvements.
Alternative 3: Convert Existing HOV Lane to Two ExpressLanes NonStandard Lane and Shoulder Widths.
This build alternative would convert the existing HOV lane to an ExpressLane and add a second ExpressLane in each direction between I10 and US101.
The freeway would be widened and restriped to accommodate the two ExpressLanes with a buffer separating the ExpressLanes from the generalpurpose lanes. Dynamic pricing would be deployed in the ExpressLanes to ensure trip reliability and traffic flow.
Installation of toll and communication infrastructure and modification/
installation of overhead signs would be required. Alternative 3 proposes to widen the freeway to the outside in order to accommodate the proposed two-lane ExpressLane facility as described. Non-standard lanes and shoulders would be provided to accommodate for the addition of the new ExpressLanes as part of Alternative 3. Retaining walls would be provided where required to minimize and avoid ROW acquisition. The reduction of shoulder and lane widths allows for accommodation of the proposed twolane ExpressLane facility without significant proposed roadway widening.

following conditions, additional roadway widening may be required:
12-foot wide weaving lane at ExpressLane ingress/egress locations.
Widening of inside/outside shoulders to maintain sight distance.
Other improvements include construction of retaining walls and sound walls, utility improvements, and drainage improvements.
Alternative 4: Convert Existing HOV Lane to Two ExpressLanes Standard Lanes and Shoulder Widths.
This build alternative would convert the existing HOV lane, between I10 and US101, to an ExpressLane in each direction, and a second ExpressLane in each direction would also be added, while providing standard lane widths, shoulder widths and stopping sight distances. The freeway would be widened and restriped to accommodate the two ExpressLanes with a buffer separating the ExpressLanes from the general-purpose lanes. Dynamic pricing would be deployed in the ExpressLanes to ensure trip reliability and traffic flow.
Installation of toll and communication infrastructure and modification/
installation of overhead signs would be required. Alternative 4 proposes to widen the freeway to the outside in order to accommodate the proposed standard two-lane ExpressLane facility as described. Retaining walls would be provided where required to minimize and avoid ROW acquisition.
Reconstruction of some existing freeway structures would be required to implement Alternative 4s standard roadway cross-section. Other improvements include construction of retaining walls and sound walls, utility improvements, and drainage improvements.
Alternative 5: Add an Additional HOV Lane Non-standard Lane and Shoulder Widths. This build alternative would add an additional HOV lane, between I10 and US101, in each direction. The freeway would be widened and restriped to accommodate the two HOV lanes with a buffer separating the HOV lanes from the general-purpose lanes. Alternative 5
proposes to widen the freeway to the outside in order to accommodate the proposed two-lane HOV facility as described. Non-standard lanes and shoulders would be provided in order to accommodate for the addition of the new HOV lane as part of Alternative 5.
Retaining walls would be provided where required to minimize and avoid ROW acquisition. The reduction of shoulder and lane widths allows for accommodation of the proposed twolane HOV facility without significant proposed roadway widening. However,
