1. SB 375 Implementation Life-Cycle
• Conceptual
• Overview of the process
– For GIS tools evaluation
– Emphasis on local governments/cities
• SCAG detailed schedule

4. Methodology
• Quantify VMT reduction
– To be based on an integrated land use and
transportation model
– PECAS Model

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

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

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

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?

Transit Oriented Developments

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

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

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

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 Pomona
C G I S R Center for Geographic Information Science Research

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
