Mr.Jolley February 13, 2020 Page 12 of 15 Assumptions: KD Anderson has identified the number and nature of study facilities in the traffic impact study (i.e., intersections, roadway segments, and freeway rampjunctions) and presented the analysis techniques (e.g., travel forecasting models and level of service analysis methods) based on their recent experience with other projects in San Joaquin County in general and in the north Stockton area in particular. In addition to evaluation of traffic impacts based on current Level of Service standards, KDA will include evaluation of the project's impacts relative to regional Vehicle Miles Traveled (VMT). Study Scenarios. KDA proposes to analyze the following development scenarios: Existing Conditions, Existing Plus Project Phase 1 Alone, Existing Plus Project Buildout, Existing Plus Approved Projects (EPAP) No Project Conditions, EPAP Plus Project Buildout, Cumulative (2035) No Project Conditions, and Cumulative Plus Project Buildout. It should be noted that this proposal does not include quantitative analysis of project alternatives. Quantitative analysis of project alternatives would require a budget augmentation. Methods. KDA will employ LOS analysis techniques accepted by San Joaquin County, Caltrans and the City of Stockton with their respective jurisdictions. KDA will consult with City staff to determine whether the methods noted in their adopted guidelines remain applicable or whether current HCM techniques should be employed. Setting. KDA will collect traffic volume count data for the study facilities and use applicable techniques to establish the existing setting conditions. KDA assumes the analysis will address an area generally bounded by Armstrong Road on the north, Lower Sacramento Road on the west SR 99 on the east and Morada Lane on the south. Within that area we propose to assess up to twenty (20) existing intersections to be selected in consultation with San Joaquin County staff and three (3) intersection created with the project. KDA will address the operation of up to ten (10) roadway segments, including mainline SR 99. Ramp merge-diverge operations will be evaluated at the SR 99/ Eight Mile Road interchange. Current facilities for alternative transportation modes will be identified and planned improvements will be noted. Project Characteristics. KDA will identify site trip generation based on ITE rates for hospitals, clinics or MOB. KDA will identify the project trip distribution based on traffic model select analysis or consideration of the project's identified service area. Creation of EPAP and Long-Term Cumulative Conditions. KDA will work with San Joaquin County staff to review available travel demand forecasting tools and select the applicable approach for this analysis. 12 ECORP Consulting,Inc.
