OVERVIEW AND BACKGROUND OF THE PLAN – Section 2

The Regional Transportation Development Mitigation Plan of the County of San Bernardino (hereafter “THE PLAN”) has been developed to satisfy the provisions of the San Bernardino County Congestion Management Plan (CMP). Pursuant to Measure I 2010-2040, the County CMP was updated and adopted by the County Congestion Management Agency, San Bernardino Associated Governments (SANBAG), in November 2, 2005. Each local jurisdiction, including the County of San Bernardino, is required to adopt a regional transportation development mitigation program prior to November 2006. Failure to adopt a program that is compliant with the CMP may result in significant loss to the County of State Gas Tax, regional Measure I, and federal/state grant funding necessary for the ongoing maintenance of and improvements to the County Maintained Road System (CMRS). The SANBAG Development Mitigation Nexus Study (SANBAG Nexus Study) determines the fair-share contributions from new development for each local jurisdiction. The total development fair-share of cost, or “target share amount” for which the County is responsible to generate through THE PLAN is $197 million, which includes the required SANBAG required 12.9% cost escalation factor for FY 2004/2005. This total is distributed among the PLAN SUBAREAS based upon project lists and growth forecasts. THE PLAN is intended to generate only the development fair-share contribution of project costs as required by the CMP and is not intended to provide 100% funding for or construct all projects listed in THE PLAN. Additional regional Measure I and federal/state funds administered by SANBAG are required for full funding of projects listed in THE PLAN. 

PLAN BOUNDARIES – Section 3

THE PLAN contains sixteen (16) PLAN SUBAREAS, twelve (12) of which represent unincorporated areas within the San Bernardino Valley and four (4) of which represent unincorporated areas within the Victor Valley. With two exceptions, the boundaries of these PLAN SUBAREAS correspond to the boundaries of the city spheres of influence as defined by the Local Agency Formation Commission (LAFCO) of San Bernardino County. The two exceptions are urbanized unincorporated areas in the San Bernardino Valley that are not contained in any city’s sphere of influence, the Redlands “Donut Hole” and the Devore/Glen Helen areas.   

1. Adelanto Sphere of Influence
2. Apple Valley Sphere of Influence
3. Chino Sphere of Influence
4. Colton Sphere of Influence
5. Devore/Glen Helen Unincorporated Areas
6. Fontana Sphere of Influence
7. Hesperia Sphere of Influence
8. Loma Linda Sphere of Influence
9. Montclair Sphere of Influence
10. Redlands “Donut Hole” Unincorporated Area
11. Redlands Sphere of Influence
12. Rialto Sphere of Influence
13. San Bernardino Sphere of Influence
14. Upland Sphere of Influence
15. Victorville Sphere of Influence
16. Yucaipa Sphere of Influence

GROWTH FORECASTS – Section 4

REGIONAL TRANSPORTATION FACILITY PROJECTS – Section 5

A list of Major Arterial Road projects was developed for each PLAN SUBAREA consisting of all County maintained roads with an existing Master Plan classification of Secondary or greater, as designated in the 1989 General Plan Circulation Element. Although not a requirement of the CMP or the SANBAG Nexus Study, County Public Works also developed a list of traffic signal projects for inclusion in THE PLAN. Traffic Signal projects were identified for construction wherever two of THE PLAN’S major arterial road projects intersect and a signal does not exist currently. The list of freeway interchange projects was compiled by SANBAG as part of its Nexus Study. The list was originally based upon the interchanges submitted by SANBAG and local jurisdictions for the 2004 Regional Transportation Plan (RTP) and then modified for the Nexus Study after local jurisdiction input. SANBAG also compiled a list of Railroad Grade Separation projects for inclusion in its Nexus Study. Only freeway interchange and grade separation projects on the SANBAG Nexus Study Network were included in THE PLAN.

PROJECT COST ESTIMATES – Section 6

Within each PLAN SUBAREA, specific projects have been identified as regional transportation facilities. The project costs associated with each project identified in THE PLAN are for additional traveled roadway only and include engineering, environmental, right-of-way, construction, and administrative overhead costs. Environmental impact mitigation such as purchase of habitat for endangered species is not included. Where another local agency shares jurisdiction with the County for a project, costs are prorated between the jurisdictions based upon actual road miles within each jurisdiction, and only the County’s share of the project cost is identified in THE PLAN. County Public Works’ staff conducted a Project Cost Estimate Study to determine an average lane-mile cost for major arterial road improvement projects included in THE PLAN (Appendix 3). For traffic signal installation projects, costs were calculated based upon historical contracts and unit prices and fiscal year 2005/2006 engineer’s estimates for signal installation projects currently in progress but not yet awarded for construction. THE PLAN utilized SANBAG Nexus Study costs for Freeway Interchanges and Railroad Grade Separation projects. An administrative overhead cost was calculated for major arterial and traffic signal projects consistent with the formula used for the Measure I administrative overhead rate. Currently, all indirect costs for labor, services, supplies, and overhead are paid initially out of the County Road Fund. THE PLAN will reimburse the County Road Fund for THE PLAN’S share of those indirect costs. This is consistent with existing Department policy concerning reimbursement of the County Road Fund from Measure I revenues through direct labor costs attributable to Measure I projects.
