    ABOUT THE TRANSPORTATION CONCEPT REPORT

    System Planning is Caltrans long-range (20-25 years) transportation planning process for evaluating existing and future operations and mobility. The System Planning process fulfills Caltrans statutory responsibility as owner and operator of the State Highway System (SHS) (California Government Code 65086 and Title 23 of the Code of Federal Regulations (CFR) Part 450 Subpart B) by identifying deficiencies and proposing improvements to the SHS. Through System Planning, Caltrans focuses on developing an integrated, multimodal transportation system that meets Caltrans goals of safety and health, stewardship and efficiency, sustainability, livability and economy, system performance and organizational excellence. System Planning is a continuous, comprehensive, and cooperative process that considers the entire transportation system, including highways, local roads, transit, freight and non-motorized modes of transportation.

    The System Planning process is primarily composed of several parts: the District System Management Plan (DSMP), the Transportation Concept Report (TCR), the Corridor System Management Plan (CSMP), the Priority Listing of Projects/DSMP Project List and the Interregional Transportation Strategic Plan (ITSP).

    The districtwide DSMP is a strategic policy and planning document that focuses on maintaining, operating, managing, and developing the transportation system. The TCR is a planning document that identifies the existing and future route conditions as well as future needs for each route on the SHS. The CSMP is a complex, multi-jurisdictional planning document that identifies future needs within corridors experiencing or expected to experience high levels of congestion. The Priority Listing of Projects is a list of the Districts planned and partially programmed transportation projects used to recommend projects for funding. These System Planning products are also intended as resources for the public and private stakeholders and for regional and local agencies. The TCR is a report and is not considered a plan under the California Environmental Quality Act (CEQA) of 1970 and the National Enviromental Policy Act (NEPA) process of 1969.

    TCR Purpose

    Californias State Highway System needs long range planning documents to guide the logical development of transportation systems as required by California Government Code 65086 and as necessitated by the public, stakeholders, and system users. The purpose of the TCR is to evaluate current and projected conditions along the route and communicate the vision for the development of each route in each Caltrans District during a 20-25 year planning horizon. The TCR is developed with the goals of increasing safety, providing excellent stewardship, sustainability, system performance and organizational excellence through the use of integrated management of the transportation network, including the highway, transit, pedestrian, bicycle, freight, operational improvements and travel demand management components of the corridor.

    STAKEHOLDER PARTICIPATION

    Stakeholder participation was sought throughout the development of this TCR. Outreach involved both internal and external stakeholders including the Southern California Association of Governments (SCAG), the Ventura County Transportation Commission (VCTC) and cities along the corridor were asked to review the document for comments, edits, and to ensure consistency with their existing plans, policies, and procedures. The process of working closely with stakeholders adds value to the TCR by reflecting the local stakeholder perspective on needs, priorities, and plans.

    EXECUTIVE SUMMARY

    The main purpose of this Transportation Concept Report (TCR) is to evaluate current and projected conditions along a route and suggest a configuration for State Route (SR) 23 that will meet projected demand. Historically, the freeway and highway system in Southern California has been highly congested and will increasingly be heavily congested into the future. Due to financial, environmental, right of way and political constraints, it has become increasingly difficult for Caltrans to continue to add more lanes to the system. The region is also limited by planned capacity increasing projects ability to meet air quality conformity status. Capacity enhancing projects have been led by local Regional Transportation Planning Agencies and generally funded through local sales tax measures and limited state and federal funding. Recognizing these constraints, the planned and programmed projects and strategies in the TCR are made within a framework of programming and implementation constraints and regional policy. The concept attainment configuration is meant only to show the severity of future conditions and what it would take to attain that level of service (LOS).

    The TCR for SR-23 is divided into several major sections; three of the sections the Corridor Performance, System Characteristics and Corridor Concept are the core of the document. The remaining provide a context for analyzing the SR-23 corridor and include a documentation of resources.

    SR-23 is a north-south intraregional route that originates in the city of Malibu (Los Angeles County) at SR-1, Pacific Coast Highway (PCH) and terminates in the city of Fillmore (Ventura County) at SR-126. Commuters from Fillmore and Moorpark use this route to access the 118 and the 101. It also provides recreational access to the beach and the Santa Monica Mountains.

    Traffic volume is forecasted to increase on SR-23 ranging from 1,500 Annual Average Daily Traffic (AADT) to 96,000 AADT according to SCAGs 2016-2040 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) modeling data. The LOS during the peak hour will be similar to current conditions. No addtional capacity is required to achieve an acceptable concept LOS.

    A portion of SR-23 (from SR-1 to US-101) is on the Caltrans District 7 list of routes recommended for relinquishment. This TCR is only reflecting the Caltrans desire to relinquish non-primary routes to the local jurisdictions. All issues and concerns will have to be negotiated and agreed to by all concerned parties before any relinquishment proposal is finalized. While doing the system analysis for the TCR, Caltrans mission to provide a safe, sustainable, integrated and efficient transportation system to enhance Californias economy and livability provide guidance and a context for recommendations.

    CONCEPT SUMMARY CONCEPT 2035 FACILITY

    The table below depicts the traffic conditions on SR-23 projected for the year 2040. The Concept LOS indicates how many lanes it will require to achieve the desired LOS.

    CONCEPT RATIONALE

    SR-23 is a north-south intraregional state route that provides access from Fillmore and Moorpark in Ventura County to SR-118 and US-101. It also provides access to the Santa Monica Mountains, SR-1 and the beach in Los Angeles County. The portion of this route from U.S. 101 to SR-126 is part of the California Freeway and Expressway System.

LOS D attainment indicates how many lanes it would require to achieve LOS D. It is meant to show the severity of future conditions and what it would take to achieve LOS D. Caltrans is not suggesting that it is the Department's plan to build the facility to achieve the LOS D.* The number of lanes in the LOS F0 attainment column is for both directions. The data in the LOS F0 attainment column is intended to show the severity of congestion on the system and what it would require to achieve that LOS. Caltrans recognizes the difficulty in achieving the desired LOS given the financial, environmental, right of way and political constraints.* Sometimes the model output implies that there would be auxiliary lanes (each direction) and auxiliary lanes are given only half capacity. That is why instances where an odd number of lanes is shown for both direction.* The 2040 Baseline includes all planned and programmed projects in SCAG's2016-2040 RTP/SCS.* For consistency with SCAG's 2016-2040 RTP/SCS, year 2012 and 2040 were used.* 2012 & 2040 data is derived from the SCAG's 2016-2040 RTP/SCS model. Data in this report is meant to be used for comparison purposes only and is not to be used for specific projects without further analysis.
