Soil Investigations for Data Collection in the Delta Initial Study/Proposed Mitigated Negative Declaration 186 highway, place, change, or renew an encroachment. The road commissioner may also require a satisfactory bond be paid. In the Study Area, Impact Areas associated with transportation under county jurisdiction that could be affected by the Proposed Project include: • Contra Costa County Road – Byron Highway; • Sacramento County Road – Lambert Road; • San Joaquin County Roads - W Walnut Grove Road, and N Staten Island Road; and. • Yolo County Roads – Clarksburg Road, and N Courtland Road. Caltrans is responsible for planning, designing, constructing, operating, and maintaining all state-owned roadways throughout the state. Federal highway standards are implemented in California by Caltrans. Caltrans has jurisdiction over State highways and sets maximum load limits for trucks and safety requirements for oversized vehicles that operate on highways. Caltrans requires a traffic analysis be conducted depending on the number of trips conducted at different levels of service conditions. In the Study Area, Impact Areas under Caltrans jurisdiction that could be affected by the Proposed Project include: State Route 160, State Route 4, State Route 104 - Twin Cities Road, State Route 220, and State Route 84. CEQA Guidelines Section 15064.3 establishes a new method for analyzing certain transportation impacts created by a project. Under the new requirements, circulation impacts must be analyzed based on vehicle miles traveled (“VMT”). VMT “refers to the amount and distance of automobile travel attributable to a Proposed Project. Other relevant considerations may include the effects of the Proposed Project on transit and non-motorized travel.” (CEQA Guidelines, section 15064.3, subd. (a).) With this update to the CEQA guidelines, the Proposed Project’s potential “effect on automobile delay shall not constitute a significant environmental impact.” Each Lead Agency is responsible for establishing their own thresholds of significance and may elect to be governed by the provisions of this section immediately or wait until the July 1, 2020 deadline. While the General Plans for Alameda, Contra Costa, Sacramento, San Joaquin, Solano, and Yolo Counties outline goals and policies that include reduction of VMTs, they have not yet adopted VMT standards pursuant to Section 15064.3 of the CEQA guidelines. 3.17.2 Discussion a) Conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? Less than Significant Impact. The Proposed Project consists of soil ingestions, which are temporary in nature and would not permanently alter the circulation system, including transit, roadway, bicycle, and pedestrian facilities, or alter the use of these facilities. The Proposed Project does not conflict with local VMT standards, as the counties which the Study Area is located have not yet adopted these standards.
