SANBAG Development Mitigation Nexus Study November 7, 2007 Page 2 of 24 The requirements of the SANBAG Development Mitigation Program are included in Chapter 4 of the CMP ("Land Use/Transportation Analysis Program") and in CMP Appendix J. Chapter 4 and Appendix J were approved by the CMA on November 2, 2005, along with other revisions to the CMP. Appendix J of the CMP provides the specific requirements local jurisdictions must follow in implementing their development mitigation program for regional transportation facilities. The San Bernardino County CMP implements the Land Use/Transportation Analysis Program with two distinct approaches, depending on geographic location within the County. The first approach addresses the cities and associated spheres of influence in the San Bernardino Valley and Victor Valley, to which the Nexus Study and related development mitigation requirements apply. The second approach applies to all other areas of the County. These two approaches are summarized below: For San Bernardino Valley and Victor Valley cities and sphere areas: local jurisdictions implement development mitigation programs that generate development contributions for regional transportation improvements equal to or greater than fair share contributions determined through the SANBAG Development Mitigation Nexus Study. Regional transportation facilities addressed by the Nexus Study include freeway interchanges, railroad grade separations, and regional arterial highways on the Nexus Study Network. Local jurisdiction development mitigation programs must comply with requirements established in Appendix J of the CMP. Each local jurisdiction has adopted a compliant development mitigation program based on the requirements established in this appendix and implemented in accordance with Chapter 4 and Appendix J of the CMP. 2. For areas outside the San Bernardino Valley and Victor Valley cities and spheres: local jurisdictions must prepare Traffic Impact Analysis (TIA) reports for proposed development projects exceeding specified thresholds of trip generation. This is a continuation of a requirement established when the CMP was originally approved by the SANBAG Board in 1992. TIA reports must comply with requirements contained in Appendix C of the CMP. At their discretion, jurisdictions outside the Valley and Victor Valley may adopt Approach 1, in coordination with and subject to the approval of the SANBAG Board. However, an amendment to the Nexus Study will be required for this to occur. Overview of the Nexus Study The SANBAG Nexus Study shall be used as the basis for identifying fair share contributions from new development for regional transportation improvements (freeway interchanges, railroad grade separations, and regional arterial highways). The Nexus Study will be updated periodically in close coordination with local jurisdictions. The Nexus Study identifies a Nexus Study Network, representing regional roadways in the urbanized areas of San Bernardino County. Roadway improvement projects must be located on SANBA GNexusStudy071107. doc
