District 9 Transportation Planning
District 9 Division of Transportation Planning plays an important role for the Department. The division articulates a long-term vision while supporting transportation service, project selection, project delivery, and system operations in the Counties of Mono, Inyo, and Eastern Kern. On a daily basis, staff collects and presents data, analyzes alternatives, drafts plans to guide and protect State transportation investments, and makes presentations to decision-makers. The District 9 Division of Transportation Planning prides itself as a leader in the transportation planning field, working in partnership with all stakeholders to ensure an open and equitable process while acting as a bridge between the Department's external partners and internal operations.
The District 9 office provides planning services for Inyo, Mono and Eastern Kern Counties. This includes review of private development projects and other governmental agency projects. The district liaison for agencies and private parties may be reached at (760) 872-0785.
Feasibility Study Report for Wildlife Vehicle Collision Reduction in Caltrans District 9
Caltrans Mission is to provide a safe, sustainable, integrated and efficient transportation system to enhance California’s economy and livability. Transportation allows for the movement of people and goods through various modes of travel, however many of these modes impact the natural environment. True to its mission and as stewards of the California State Highway System, Caltrans has a responsibility to seek a balance for the needs of travelers, safety, and the environment.
During the spring and fall deer migration season, travelers note an increase in wildlife vehicle collisions (WVCs) along California’s Highways. Though the increase in WVCs may be evident from an empirical perspective, Caltrans District 9 has never undertaken an engineering and science based approach using modern technology and analysis on this issue. Therefore, it was determined that such a report would help identify if there is a higher than statewide average of WVCs in Caltrans District 9, location hotspots, and what type of mitigation treatments could potentially mitigate WVCs. By identifying these locations, Caltrans, in partnership with other agencies and organizations can investigate best practices for potential mitigation efforts to reduce WVCs.
The purpose of this Feasibility Study Report (FSR) is to evaluate the frequency of wildlife vehicle collisions (WVCs) in Caltrans District 9, to identify localized areas with the highest concentration of collisions, and to evaluate concepts that would reduce WVCs where concentrations are found.
State Transportation Improvement Program (STIP)
The State Transportation Improvement Program is a multi-year capital improvement program of transportation projects on and off the State Highway System, funded with revenues from the State Highway Account and other funding sources. For more information, see Departments web site: http://www.dot.ca.gov/hq/LocalPrograms/STIP.htm
Bishop Area Access & Circulation Feasiblity Study (BAACS)
In 2003 the Inyo County Local Transportation Commission, with the support of the City of Bishop and Inyo County, requested that Caltrans District 9 conduct the Bishop Area Access and Circulation Study. The study was developed in a collaborative fashion with the project proponents mentioned above, the Bishop Paiute Tribe, local Chamber of Commerce and businesses, local public service entities, local schools, the general public, and others.

Average Annual Daily Traffic Counts US 395, US 6, SR 14, and SR 58
This summary contains traffic count averages from 1992 to 2015 for the District's major routes in a graph format. It also includes a break-out of truck data from 2006 to 2015.

Goods Movement Study for US 395 Corridor
The California Department of Transportation (Caltrans) District 9 commissioned a goods movement study of the US-395 corridor that was initialized during the summer of 2005. The southern limits of the study area include a portion of US-395 and SR-14 near Ridgecrest. The northern limits of the study area include a portion of US-395 and US-6 up to the Nevada border. Figure 1 shows the study area. The study area extends through Kern County, Inyo County and Mono County. Major cities/towns within the corridor include Ridgecrest, Lone Pine, Independence, Big Pine and Bishop.
US 395 Origination and Destination Study
The US 395 Origination and Destination (O&D) Study is an interview census of passengers and vehicles entering Caltrans District 9 along the US 395 corridor. Since its start in 1979, this study has been conducted every ten years. The 2011 survey will be the fourth O&D Study conducted by District 9.
The O&D Study is accomplished by stopping traffic, observing vehicle classifications, conducting interviews, and automatically counting/classifying vehicles. Four entry points are surveyed in the winter (due to winter highway closures), and six entry points are surveyed in the summer. The accumulated data from these O&D studies has benefited not only Caltrans but our local partners: Inyo County, Mono County, City of Bishop, City of Mammoth Lakes, LTCs, local chambers of commerce, and many local businesses that rely on tourism as a primary resource. Current and future goods movement studies are greatly enhanced by the detail information on truck commodities gathered in this study.
District System Management Plan (DSMP)
The District System Management Plan (DSMP) is a long-range (20 year) strategic and policy planning document that presents the long range goals, policies and programs the district intends to follow in maintaining, managing, and developing the transportation system. It serves as a resource for informing federal, state, regional and local agencies, and the public and private sector of the plans the district intends to follow in its partnership role with local and regional agencies.
Transportation Concept Reports (TCR)
Transportation Concept Report is a long-range planning document that describes the current characteristics of the transportation corridor and establishes a twenty-year planning concept. The TCR defines the California Department of Transportation's (Caltrans) goal for the development of the transportation corridor in terms of level of service (LOS) and type of facilities, and broadly identifies the improvements needed to reach those goals.
Facility information (e.g., roadway widths, number of lanes) contained in the TCR represents a preliminary planning approach to identifying candidate improvements and to determining estimated costs. All information in TCR documents is subject to revision as conditions change and new information is obtained. Consequently, the nature and the size of identified improvements may change as they move through the project development stages. Final determinations are made at the time of project planning and design.
