Although the base year set by federal agencies for the RTP is 2008, CARB has identified
2005 as the initial year for calculating GHG emissions reduction. In other words, the
amount of GHG reduction achieved through the region’s collective sustainable
community strategy will be measured by comparing projected GHG emissions for 2020
and 2035 against GHG emissions that occurred in 2005. All projects, programs, and
policies put into place after 2005 to help reduce GHG emissions will be included in the
analysis of the region’s GHG emissions reductions.
THE SUBREGIONAL SCS
Unique to the SCAG region, SB 375 provides for a subregional council of governments
and county transportation commission to work together to propose the SCS for a
subregional area. Orange County is one of these subregional areas. As allowed, OCCOG
and OCTA have agreed to prepare the OC SCS.
Orange County’s subregional effort aims to ensure an accurate reflection of existing and
planned local land uses, conditions, and activities. Additionally, the OC SCS
demonstrates that the subregion is already undertaking strategies to reduce GHG
emissions through existing and planned transportation projects and programs; showcases
Orange County’s longstanding history of integrating land use and transportation
planning; and facilitates and supports the ongoing leadership and innovation occurring in
Orange County towards sustainable land use and transportation practices.
To reiterate, no subregional GHG emissions reduction targets were set by CARB or
SCAG. GHG emission reduction targets are only calculated at the regional level.
A Memorandum of Understanding (MOU) among SCAG, OCCOG, and OCTA
formalized the roles and responsibilities of each party related to the preparation and
acceptance of the Orange County subregional SCS as it relates to the SCAG Regional
SCS. In summary, SCAG is required to prepare the regional SCS, and OCCOG and
OCTA are tasked with preparing the OC SCS consistent with SCAG’s adopted
Framework and Guidelines. SCAG must include the OC SCS in the SCAG Regional SCS
and RTP. The MOU and SCAG Framework and Guidelines are in Appendix B.
PUBLIC PARTICIPATION IN THE SCS
SCAG is leading the public participation process for the SCAG Regional SCS. As part of
their public outreach effort, SCAG will hold informational meetings, workshops, and
public hearings on the draft SCS including some in Orange County, in order to solicit
input and recommendations. Additionally, the OCCOG Board will augment the regional
public participation effort with local outreach for the OC SCS. A description of the
