Inyo County Local Transportation Commission

The Inyo County Local Transportation Commission (ICLTC) is a six-member commission that serves as the State mandated Regional Transportation Planning Agency (RTPA) for Inyo County. Representation on the ICLTC consists of two members each from the Inyo County Board of Supervisors and the Bishop City Council, while the remaining two seats are Board and Council appointed at-large representatives. The Inyo County Public Works Director serves as the Executive Director of the ICLTC. Follow the corresponding link to view the ICLTC By-Laws and Organization and Procedures Manual.


 The ICLTC prepares an annual Overall Work Program and a Regional Transportation Plan every four years, as well as programming projects into transportation improvement programs. The ICLTC also administers Transportation Development Act (TDA) funds and prioritizes grant funding endorsements from a variety of programs. The TDA involves two major funding sources: the Local Transportation Fund (LTF) and the State Transit Assistance Fund (STA). TDA funds can be used by the City of Bishop and the County of Inyo for transportation planning, expenses related to administering the TDA, pedestrian and bicycle facilities, the transit system, and/or for street and road projects. STA funding is allocated to transit operators and is a second source of TDA funding for transportation planning and mass transportation purposes. The ICLTC convenes noticed public hearings on the third Wednesday of every month to address transportation issues.

Inyo County LTC works in cooperation with various state agencies and other planning organizations throughout the state to ensure a coordinated approach to transportation planning. Inyo County LTC is a member of the Eastern California Transportation Planning Partnership. The Eastern California Transportation Planning Partnership comprises representatives from Inyo, Kern, Mono and San Bernardino counties, and Caltrans. It is intended to address transportation corridors of mutual concern, such as State Routes 14, 58 and U.S. 395. Route improvements in eastern California will ensure that vital tourism, public transportation and freight movement interests among all regions are properly addressed over the next several decades. 

If you have any questions, comments, or other feedback, please call (760) 878-0202 or send LTC staff an e-mail message.

Regional Transportation Improvement Program (RTIP)

The Inyo County LTC is responsible for the preparation of the Regional Transportation Improvement Program (RTIP), in collaboration with Caltrans, and submitted for adoption by the California Transportation Commission (CTC). Inyo County LTC submits its RTIP to the CTC for potential inclusion in the State Transportation Improvement Program (STIP). The RTIP, at its core, specifies project cost amounts by project components and the fiscal year in which funds are available.

The STIP is a biennial document adopted no later than April 1 of each even numbered year. Each STIP will cover a five year period and add two new years of programming capacity. Each new STIP will include projects carried forward from the previous STIP plus new projects and reserves from among those proposed by regional agencies in their RTIPs and by Caltrans in its interregional transportation improvement program (ITIP). The Caltrans Division of Local Assistance provides guidelines for local agencies to deliver projects included in the STIP.

 The STIP consists of two broad programs, the regional program funded from 75% of new STIP funding and the interregional program funded from 25% of new STIP funding. The 75% regional program is further subdivided by formula into county shares. County shares are available solely for projects nominated by regions in their RTIPs. The Caltrans ITIP will nominate only projects for the interregional program. 

The current structure of the STIP was initiated by SB 45 in 1997. The STIP is constrained by the amount of funds estimated to be available for the STIP period in the fund estimate, which is developed by Caltrans and adopted by the Commission every other odd year. The amount available for the STIP is then constrained by formulas for regional and interregional shares per Streets and Highways Code.

Inyo County LTC RTIP

The Inyo County LTC approved its 2024 RTIP following a public hearing on November 29, 2023. The funding for the STIP is more robust than it has been for the last several cycles because of SB 1. Effective 2019-20, SB 1 resets the price based excise tax to 17.3 cents with the provision to adjust it annually for inflation. This has helped to stabilize the funding for the State Highway Account that is directed to fund the STIP. The 2024 STIP Guidelines and the Fund Estimate can be viewed by following the corresponding links. 

MOU’s on the State Highway - The Inyo County Local Transportation Commission (LTC) entered into MOUs in 1998 and 2001 for several projects on the US Highway 395/State Route 14 Corridor.  The signatories to this MOU were the Inyo County LTC, Mono County LTC, and Kern Council of Governments (Kern COG). These agencies jointly committed to use Regional Improvement Program (RIP) shares programmed in each agency’s RTIP. The purpose of the MOUs was to move forward regionally significant projects that leveraged state controlled Interregional Improvement Program funding to be used in the US 395/SR 14 corridor.  The MOU partnership resulted in significant improvements to safety for interregional and local users of the corridor.  The final MOU partnership terminated during the 2022 STIP cycle.

ITIP - The 2024 Draft Interregional Transportation Improvment Program (ITIP) has been released by Caltrans and will be incorporated into the 2024 STIP by the CTC on March 21-22, 2024. The 2024 ITIP includes safety improvements to the Freeman Gulch project in Kern County. 

Public Transportation

Senate Bill 402 Monitoring and Reporting (Combined Use)

All County maintained streets and roads (paved or dirt) are considered to be ‘highways’ under the California Vehicle Code. Currently, the combined-use of County maintained roads by OHV is only allowed on the seven approved combined-use routes described below. The project proponents who proposed these combined-use routes refer to the routes as "Adventure Trails."

Background: At a public hearing on January 22, 2015 the Board of Supervisors approved 7 combined-use routes. On July 14, 2015, the Independence No. 1 combined use route was opened for combined use by qualifying OHVs. On July 24, 2015, the Lone Pine No. 1 combined use route also opened for qualifying vehicles. Bishop Routes No. 5, 6, 7, 9 & 15 were opened for combined use between August 5, 2015 and September 5, 2017. Maps showing those routes can be viewed by following the corresponding links. Each map shows the conditions placed on each user of the combined-use routes.

Assembly Bill 628 and then Senate Bill 1345 made revisions to the California Vehicle Code establishing a pilot project allowing Inyo County to designate specific County highways (streets and roads) as combined-use routes. The future designation of combined use routes would allow the use of County streets and roads by Off-Highway Vehicle (OHV). On May 8, 2012, the Board of Supervisors adopted implementing procedures for the designation of combined-use routes. 

Assembly Bill 628 and then Senate Bill 1345 authorizes the County of Inyo to establish a pilot project to designate combined-use highways on unincorporated county roads for no more than 10 miles. The combined-use highways can be used to link existing off-highway motor vehicle trails and trailheads on federal Bureau of Land Management (BLM) or United States Forest Service lands in order to provide a unified linkage of trail systems for off-highway motor vehicles. Other goals for the project are to preserve traffic safety, improve natural resource protection, reduce off-highway vehicle trespass on private land, and minimize impacts on county residents. The initial authorization (AB 628, 2011), which amends Vehicle Code section 38026, was in effect through January 1, 2017, but has twice been extended, and is now authorized through January 1, 2025 (SB 1345, 2016; SB402, 2019). The County is required to submit a report for SB402 to the Califoria Legislature before January 1, 2024.

OHV users on all combined-use routes must:

  • Drivers must have in possession a valid driver’s license of the appropriate class for the vehicle being operated.
  • Ride during daylight hours only and not earlier that 7:00 am and no later than 8:00 pm.
  • Have an operational stop light.
  • Have insurance in accordance with the provisions of article 2 (commencing with Section 1160230) of Chapter 1 of Division 7 of the California Vehicle Code.
  • Obey the posted speed limit for OHVs on combined-use roads and, in residential areas, drive no faster than 15 mph.
  • Use a vehicle that has rubber tires.
  • Pass at least three (3) feet away from bicyclists, horses, and pedestrians.
  • Slow to 5 mph when passing horses or pedestrians.
  • Ride only on existing trails.
  • Not stop in flowing water.
  • Drive in the middle of the vehicle lane.
  • Not drive on the shoulder.
  • Use existing trails when exiting a combined-use route.
  • OHV operators must operate the OHV in accordance with the vehicle manufacturer’s recommendation for use of the vehicle

Environmental Review: Inyo County released a Draft Environmental Impact Report for the consideration of a proposed system of combined-use roads known collectively as the Adventure Trails System of the Eastern Sierra. Scoping meetings were held in late October 2013 in Independence and Bishop. The public comment period ran from July 17, 2014 to September 2, 2014. 

A Final Environmental Impact Report was released on October 29, 2014. The Inyo County Planning Commission made a recommendation to the Board of Supervisors 1) to certify the FEIR, 2) to provide direction to staff on which combined-use routes to recommend to the Board, and 3) to revise the Implementing Procedures at a special November 5, 2014 meeting at 5:00 p.m. in Independence. The Board of Supervisors considered the project at a special 10:00 a.m. January 22, 2015 meeting in Independence. At the January 22nd meeting, the Board of Supervisors approved 7 routes and deferred consideration of other routes.

Public Comments: The public can comment via e-mail on any issues surrounding the designated combined-use routes  at Section 14(f) of the Inyo County Implementing Procedures state that:        

   The Public Works Department shall maintain a website that is a central hub for collecting public and public agency comments and complaints on the combined-use routes which shall include all correspondence from the public and public agencies regarding all combined use segments. 

This website serves this purpose and is a central hub for receiving comments.

Regional Transportation Plan

The Regional Transportation Plan (RTP) serves as the planning blueprint to guide transportation investments in the County involving local, state, and federal funding over the next twenty years. Transportation improvements are categorized as short-term (0-10 years) or long-term (11-20 years). The overall focus of the RTP is directed at developing a coordinated and balanced multi-modal regional transportation system that is financially constrained to the revenues anticipated over the life of the plan. The coordination focus brings the County, City of Bishop, Indian Tribal Governments, resource agencies, and citizens into the planning process. The balance is achieved by considering investment and improvements for moving people and goods across all modes including roads, transit, bicycle, pedestrian, goods, and aviation. Individual projects identified in the Regional Transportation Plan will receive further project-specific environmental review. Comprehensive updates to the RTP are supposed to be completed every 5 years. In 2014, the Inyo County LTC elected to update the RTP every 4 years after the completion of the 2015 update. As a result of this change, Inyo County and the City of Bishop are now only required to update the Housing Elements of their General Plans every 8 years.

2023 Update - the Inyo County LTC has hired LSC Transportation Consultants Inc. to complete an update of the Regional Transportation Plan. The update is required to be completed by September 15, 2023.  Public Comment on the Draft RTP was open from September 27, 2023 until October 26, 2023.  A public hearing on the Draft RTP and Negative Declaration of Environmental Impact was held in conjunction with the November 29, 2023 LTC meeting.

Pavement Management Program

Whitney Portal

The Inyo County LTC maintains a Pavement Management Program for Inyo County and the City of Bishop.  The system utilizes software that synthesizes pavement condition index (PCI) data for roads and assigns a score of 0-100.  A score of  70-100 is good to excellent, 50-69 is at risk, 25-49 is poor, and 0-24 is failed.  Each roadway is assessed every three years.

The PCI data is utilized by County and City staff to prioritize and determine the need for preservation and repairs.  The eventual goal of the program is to attain good to excellent pavement conditions allowing for best management practices that preclude the need for expensive deferred maintenance.  Reconstruction of failed roadways can cost up to five times higher than conducting routine preventative maintenace every five to seven years.  Maintaining pavement in good condition is in the best interest of the tax payers, travellng public and for the environment.
