The State Route 237 Express Lanes Phase 2 Project is part of the Silicon Valley Express Lanes Program which provides congestion relief by converting existing high occupancy vehicle (HOV) lanes to Express Lanes on I-680, SR 237, SR 85, and US 101 in Santa Clara County and allowing single-occupancy vehicles to take advantage of the underused capacity of the existing HOV lanes for a toll. The Project will convert the existing eastbound and westbound HOV lanes on SR 237 to Express Lanes between Mathilda Avenue and Zanker Road, a distance of approximately five miles. The conversion will entail restriping of the existing lanes, as well as the addition of signs and electronic tolling equipment. The conversion will have the effect of extending the express lanes that are currently in operation on SR 237 east of Zanker Road. The Project will be implemented within the existing Caltrans and intersecting local streets rights-of-way. The project will not construct new lanes of traffic or move traffic closer to adjacent land uses. See Exhibit A.

Project Purpose and Need (Summary): (please be brief)
Purpose The purpose of the project is to provide congestion relief on SR 237 in Santa Clara County by allowing single-occupancy vehicles to take advantage of the underused capacity of the existing high occupancy vehicle (HOV) lanes for a toll. Need SR 237 experiences congestion during peak weekday commute periods in the mixed-flow (i.e., non-HOV) lanes. VTA and Caltrans desire to implement the project for the purpose of reducing congestion in a manner that takes advantage of the underutilized capacity of the existing HOV lanes.
Surrounding Land Use/Traffic Generators (especially effect on diesel traffic)
The land uses surrounding the SR 237 corridor in the study area in the cities of Sunnyvale, Santa Clara and San Jose, include the following: Residential, Industrial to Residential, Moffett Park, Industry, Office/R&D, Parks/Open Space, Combined Industrial/Commercial, Industrial Park, Mixed-Use Residential, and Public/Quasi Public. See attached Exhibit B, Land Use Maps, and Exhibit C, Land Use Aerials.
Brief summary of assumptions and methodology used for conducting analysis - The traffic counts for the existing condition were taken in March 2013. - The VTA Countywide Model was used to develop future conditions with and without the project. - The AADT doesn’t change between the No Build and Build because the project does not add capacity; it provides a way to better utilize the capacity that is there during the peak periods.

No Build Build Notes: - In the Build scenario, dynamic pricing will be used to control the number of single-occupancy vehicles (SOV) entering the express lane and manage the LOS. As demand increases and the Express Lane becomes congested, the toll will increase. - The LOS for the HOV/Express Lane degrades because more vehicles use the Express Lane in the Build compared to the HOV Lane in the No Build; but not enough vehicles shift over to change the LOS in the general purpose lanes.

-
The project is not expected to result in traffic redistribution to or have impacts on other facilities. The main effect of the project is to provide congestion relief through more effective use of unused available capacity in the HOV lanes.

The project will not construct new lanes of traffic or move traffic closer to adjacent land uses. Background This project qualifies as a Categorical Exclusion under NEPA and Categorical Exemption under CEQA (CE/CE) The environmental analysis is underway and scheduled to be completed by June 2014. Seeking determination that this project is not a project of air quality concern from the Task Force on or by January 31, 2014. This information will be included in the Air Quality Report that will be submitted to Caltrans for review by February 2014. Seeking air quality conformity determination from FHWA by May 2014. Not a Project of Air Quality Concern (40 CFR 93.123(b)(1)) (i) New or expanded highway projects with significant number/increase in diesel vehicles? No. The project is not a new freeway or highway expansion project and does not significantly increase the volume or percentage of diesel vehicles. The project does not add lanes—it converts existing HOV lanes to Express Lanes. (ii) Affects intersections at LOS D, E, or F with a significant number of diesel vehicles? No. Diesel vehicles currently represent about 2,500 (2.95%) of highway traffic volume at the SR 237/US 101 junction west of the Project and 8,075 (6.26%) at the SR 237/I-880 junction east of the Project. The projected number of diesel vehicles in 2015 and 2035 within the project limits are about 4,144 (4%) and 4,860 (4%), respectively. The project does not change land uses that affect diesel traffic or increase diesel vehicles on SR 237. (iii) New bus and rail terminals and transfer points? No. The project does not construct new bus, rail terminals, or any transfer points where a significant number of diesel vehicles will congregate. (iv) Expanded bus and rail terminals and transfer points? No. The project does not expand bus or rail terminals or diesel vehicle transfer points. (v) Affects areas identified in PM10 or PM2.5 implementation plan as site of violation? - No. The project does not affect sites identified in the applicable implementation plan as sites of violation or possible violation. On January 9, 2013, the U.S. EPA issued a final rule to determine that the San Francisco Bay Area has attained the 24-hour PM2.5 National Ambient Air Quality Standard (NAAQS). This action suspends the federal State Implementation Plan (SIP) provisions that apply to preparing an attainment plan to demonstrate how the Bay Area will attain the standard.

Seeking determination that this project is not a project of air quality concern from the Task Force on or by January 31, 2014. This information will be included in the Air Quality Report that will be submitted to Caltrans for review by February 2014. Seeking air quality conformity determination from FHWA by May 2014. Not a Project of Air Quality Concern (40 CFR 93.123(b)(1)) (i) New or expanded highway projects with significant number/increase in diesel vehicles? No. The project is not a new freeway or highway expansion project and does not significantly increase the volume or percentage of diesel vehicles. The project does not add lanes—it converts existing HOV lanes to Express Lanes. (ii) Affects intersections at LOS D, E, or F with a significant number of diesel vehicles? No. Diesel vehicles currently represent about 2,500 (2.95%) of highway traffic volume at the SR 237/US 101 junction west of the Project and 8,075 (6.26%) at the SR 237/I-880 junction east of the Project. The projected number of diesel vehicles in 2015 and 2035 within the project limits are about 4,144 (4%) and 4,860 (4%), respectively. The project does not change land uses that affect diesel traffic or increase diesel vehicles on SR 237. (iii) New bus and rail terminals and transfer points? No. The project does not construct new bus, rail terminals, or any transfer points where a significant number of diesel vehicles will congregate. (iv) Expanded bus and rail terminals and transfer points? No. The project does not expand bus or rail terminals or diesel vehicle transfer points. (v) Affects areas identified in PM10 or PM2.5 implementation plan as site of violation? - No. The project does not affect sites identified in the applicable implementation plan as sites of violation or possible violation. On January 9, 2013, the U.S. EPA issued a final rule to determine that the San Francisco Bay Area has attained the 24-hour PM2.5 National Ambient Air Quality Standard (NAAQS). This action suspends the federal State Implementation Plan (SIP) provisions that apply to preparing an attainment plan to demonstrate how the Bay Area will attain the standard.
