Where We Are Headed
CO2 Emissions
• Our existing policies need to be adjusted in order to meet the target and reduce GHGs
• Small changes have big impacts
![Page 6: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/6.jpg)

Land Use Planning: What New Strategies Might Work?
• Focus growth around transit areas
• Integrate housing and jobs closer to one another
• Increase the diversity of housing choices region wide
• Reinvestment in existing communities
• Ensure local capacity for mixed use centers of activity

Anticipating the Target
• Statewide reduction5 million metric tons through land use and transportation planning by 2020
• Estimated SCAG portion 2.5 million metric tons
![Page 9: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/9.jpg)
Reaching the TargetHow far can land use planning take us as a region toward meeting the target?
• How can the region absorb expected growth?
• Need to research and test different land use and transportation planning strategies
• Want to partner and collaborate with local governments, subregions, and county transportation commissions in the development of the SCS
![Page 10: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/10.jpg)
• Research effort to test ideas, not a proposed SCS• Started with the adopted growth forecast from the 2008 RTP• Integrated 2008 RTP input and introduced new land use planning
strategies • Evaluated scenarios with a transportation and land use model, then
compared results against the 2008 Adopted RTP Forecast• Considered the strengths and weaknesses
Developing the Conceptual Land Use ScenarioResearch and Analysis
![Page 11: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/11.jpg)
2008 RTP Adopted Growth Forecast
• Developed by the region for the region• Used to compare alternative land use strategies
to reduce the regional GHG reduction target
-2.5
![Page 12: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/12.jpg)
2008 RTP Adopted Growth Forecast Strengths and Weaknesses
• Followed local input• Reflected many local initiatives
• Transportation modeling resulted in the production of 94 million tons of CO2 emissions by 2020
• Jobs/housing imbalance which leads to longer trips• Many separated land uses• Does not meet 2020 target
![Page 13: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/13.jpg)
• Part of 2008 RTP research• Focused on regional jobs-housing balance• Did not follow county or city forecasts
Envision Scenario
-2.5-2.3
![Page 14: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/14.jpg)
Envision ScenarioStrengths and Weaknesses
• Built upon current progressive planning efforts• Improved access to jobs across the region• Significantly reduced carbon emissions• Achieved a 2.3 million metric ton reduction
• Did not follow local plans in some areas –especially stable residential areas
• Some parts of scenario probably not feasible• Not fully vetted during RTP
![Page 15: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/15.jpg)
• Considered the lessons learned from the 2008 RTP Adopted Growth Forecast and Envision Scenario
• Maintained county level forecasts• Maintained city level growth forecasts within 10%• Focused growth around regional and local transit networks
Conceptual Land Use ScenarioMethodology
![Page 16: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/16.jpg)
Started with the regional 2020 transportation network
![Page 17: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/17.jpg)
Focused growth in high intensity areas based on 2006 General Plan designations as well as some vacant lower density areas
![Page 18: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/18.jpg)
Avoided areas of stability: open space and established residential areas
![Page 19: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/19.jpg)
Initially, focused growth around regional rail and rapid bus transit (BRT) and existing urban centers
![Page 20: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/20.jpg)
Established top priority growth areas: rail and BRT transit areas with both land capacity and planned capacity (high intensity General Plan designations)
![Page 21: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/21.jpg)
We expanded the top priority areas significantly by including local bus transit
![Page 22: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/22.jpg)
zAdding local transit quadrupled the top priority areas from 123,000 acres to 534,000 acres and reduced densities
![Page 23: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/23.jpg)
Conceptual Land Use Scenario
• Maintains city and county forecasts for housing and jobs• Focuses growth around transit corridors and stations• Focuses new development in areas with planned capacity
-1.5
-2.5-2.3
![Page 24: LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Hasan Ikhrata](https://reader033.vdocument.in/reader033/viewer/2022060112/55703ba8d8b42a611e8b4f32/html5/thumbnails/24.jpg)
Conceptual Land Use Scenario Strengths and Weaknesses
• Results in a reduction of 1.5 million tons of CO2• The modeling and research tells us that it is possible to significantly
reduce GHG through land use strategies• Improved jobs to housing balance and distributed growth
• Requires some new transportation investments• Requires additional TDM strategies• Modeling should take advantage of additional pedestrian and
transit trips• Requires local and regional policy changes• Did not meet the 2.5 MMT target – 60% of the way
