Administrative Draft Environmental Impact Report Gill Medical Center Project Table 4.19-3.Level of Service Criteria for Freeway Merge and Diverge Areas Level of Vehicle Density Operating characteristics Service D Greater than 28 At LOS D,turbulence levels in the influence area become intrusive,and virtually all Less than or equal to 35 vehicles slow to accommodate merging and diverging.Some ramp queues may form at heavily used on-ramps,but freeway operation remains stable. E Greater than 35 LOS E represents conditions approaching or at capacity.Small changes in demand or disruptions within the traffic stream can cause both ramp and freeway queues to form. F Demand exceeds capacity LOS F defines operating conditions within queues that form on both the ramp and the freeway mainline when capacity is exceeded by demand. Note:Vehicle density is expressed as passenger car equivalents per mile per lane. Source:Transportation Research Board 2010. The Envision Stockton 2040 General Plan (City of Stockton 2018b) notes: "The City of Stockton strives to maintain LOS D or better for peak hour intersection and daily roadway segment operations. However, in the Downtown and other areas, exceptions to this standard are permissible to support other goals, such as encouraging safe travel by other modes of transportation than the car. The City can use VMT and LOS to support non-auto transportation modes, with the ultimate goal of maintaining and enhancing a complete roadway network that serves all travel modes in a balanced and equitable way." This section of the City General Plan lists more than 14 facilities as exceptions to the LOS D policy standard, and lists the applicable standard. Among the facilities listed as exceptions is "Eight Mile Road, Lower Sacramento Road to West Lane— LOS E". Consistent with the City General Plan, a LOS E standard is applied in this draft EIR to the following study facilities under long-term Cumulative conditions: the intersection of Eight Mile Road & Lower Sacramento Road, the intersection of West Lane & Eight Mile Road, and the roadway segment Eight Mile Road between Lower Sacramento Road &West Lane. For the facilities listed above, LOS E or better is considered acceptable, and LOS F is considered unacceptable under long-term Cumulative conditions. Under near-term Existing or EPAP background conditions, a LOS E standard is applied to the facilities listed above only if the facility is considered built out to its ultimate size, or would be built out with implementation of expansion measures. SR 99 is a facility under the jurisdiction of Caltrans. While the City General Plan identifies LOS E and LOS F as standards for portions of the SR 99 corridor, Caltrans has set a LOS D standard (Dumas, pers. comm.). At the direction of City staff, because SR 99 is under the jurisdiction of Caltrans, LOS D is used as the LOS standard for the SR 99 corridor; LOS E and F are considered unacceptable. In the draft EIR transportation analysis, the Caltrans LOS D standard is applied to mainline freeway LOS, ramp junction LOS, and to LOS at freeway interchange intersections.
