LTC, Annual Forum, Greener California: Impacts of Senate Bill 375 and Winning Strategies for Southern California, 05/22/2009, Kelly Chan

  1. 1. SB 375 Implementation Life-Cycle • Conceptual • Overview of the process – For GIS tools evaluation – Emphasis on local governments/cities • SCAG detailed schedule Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  2. 2. SB 375 flow diagram Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  3. 3. SB 375 flow diagram Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  4. 4. Methodology • Quantify VMT reduction – To be based on an integrated land use and transportation model – PECAS Model Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  5. 5. Vehicle Miles Travel • Current VMT estimate is fairly straightforward – Traffic volume X length of road – Verify with gasoline sales records – Caltrans publishes annual highway miles – PeMS – Arterial highways Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  6. 6. Modeling Potential VMT Reduction • PECAS and Activity-based Models • Land use model data requirements – Density and Intensity of use • More than assessor parcels database • Mixed-uses parcels – Business Licenses Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  7. 7. SB 375 flow diagram Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  8. 8. In-fill and TOD • TODs appear in all SB 375 discussions • In-fill opportunities as well • Existing In-fill GIS Tools – Berkeley’s Infill Locator – CaLots • SCAG/UCLA Land Opportunities Tracking System Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  9. 9. GIS Tools • TOD and In-fill opportunities tools require GIS “prospecting” tools • Cities needs additional capabilities – Find out why there are in-fill opportunities? • Vacant land • Improvement-value-versus-land-value • Land Rent Gap – Find out why these opportunities are not taken up by “market”? – Where to put new opportunities?

  10. 10. Sustainable Communities Projects Sustainable Communities Projects Transit Oriented Developments Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  11. 11. Transit Oriented Development • Naïve “find parcels close to transit nodes” is not enough • Many cities will have a chicken-and-egg situation regarding TOD projects • One of the qualifying criteria for TOD projects is that they must be consistent with the development pattern in the SCS Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  12. 12. Inform the SCS process • Identify Suitable/desirable project sites • Identify Suitable/desirable transportation projects • Inform on the SCS – So that the ultimate development pattern reflects the city’s land use aspiration • Quantify possible VMT reduction resulted from those projects Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  13. 13. Other Transportation Projects • Other projects now qualify for RTIP funding to cities and counties with – Resource Area – Farmland – For the preservation and safety of city street and county road system, and – Farm to market, and – Interconnectivity transportation needs Cal Poly PomonaC G I S R Center for Geographic Information Science Research

  15. 15. Housing • Adequacy according to RHNA – Sufficient “planned” housing – Sufficient zone’d housing areas • WITHOUT A CONDITIONAL USE OR OTHER DISCRETIONARY PERMIT – Discrepancies/deficiencies – How/where to adjust? • Rezoning – Economic Analysis • General Plan and Zoning Cal Poly PomonaC G I S R Center for Geographic Information Science Research
  16. 16. Housing Allocation Tools • Summarize housing stock • Summarize planned housing • Suitability for new housing – Especially high-density housing – And, mixed-used – Consistent with SCS • General Plan and Zoning compatibility analysis Cal Poly PomonaC G I S R Center for Geographic Information Science Research
