SCAG Scenario Planning Model

As a companion tool to assist in 2016 RTP/SCS local input and scenario planning, SCAG is developing a Scenario Planning Model (SPM) based on the UrbanFootprint software platform developed by Calthorpe Associates. We believe that SCAG SPM can significantly contribute to the regional and local planning process by expanding land use scenario planning and analysis capacities while maintaining consistency across the region. SCAG plans to rollout SPM and data around October, 2013. More information can be found at:

For the model to be most useful to local jurisdictions, we would like to form a SPM working group consisting of one (or more) designated staff from selected jurisdictions. The role of the SPM working group is to provide guidance in developing a more efficient model that better serves the needs of end users such as local and regional planners. We envision that the SPM working group will be a forum for sharing ideas and expectations about the model’s functions and operations through collaborative interaction. It is also an opportunity for members to gain first-hand experience with SPM tools and data.

We are reaching out to your jurisdiction based on past participation in the SCAG 2012 RTP/SCS local input process and GIS services program as well as the status of the General Plan land use element update. Participation in the SPM working group may require approximately 10-15 staff working hours per month and 20-25 hours per month if your jurisdiction would like to participate in pilot testing (which is anticipated to begin July, 2013). We anticipate the majority of SPM working group activities to occur between May, 2013 and August, 2013.

If you are interested in joining the SPM working group, please respond by May 3, 2013 – we would greatly appreciate your participation. If you have any questions, please feel free to contact Amy Volz at or (213) 236-1919 or Guoxiong Huang at or (213) 236-1948. We look forward to hearing from you soon.
