6: Create Alternative Scenarios

Using what you have learned about your region, your community, your site, and the preferences and hopes of community residents and stakeholders, you can use ArcGIS, Envision Tomorrow +, and and the design guidance and reporting utility of StreetPlan to create and evaluate alternative scenarios. This is an opportunity to experiment and learn with your stakeholder group, exploring a range of options that capture ideas from your stakeholders and the public, and are informed by your prior analysis and research.

Key tasks

  • Decide what to hold constant in the scenarios (i.e. population and employment growth) to make it possible to isolate the impact of various changes you want to see.
  • Scenario experimentation by staff/core group/stakeholders.

Key questions

Building-level scenarios

What zoning or development regulation changes have the most significant impact on development feasibility? Are any of the buildings that aren't currently feasible so important that you want to experiment with financing tools to make them feasible?

Planning Area scenarios

What does the current zoning / plans envision for this area? What are the themes that came from the hands-on public workshops? How can scenarios meet specific policy objectives (i.e. affordability, transportation efficiency)?

Test scenario responsiveness to community values

ET+ evaluation indicators and applications may be useful.

Depending on community values, key questions may include:

Growth Costs and Revenues: What are the costs and revenues associated with future growth scenarios? To what extent can positive future revenues be leveraged in the short term to spur private investment?

ET+ Fiscal Impact Model

Amenities: How will the presence of existing or future amenities impact development feasibility by increasing achievable rent or sales price?

Parking: How does the mix of uses in a scenario decrease peak parking demand and reduce the need for investment in an oversupply of parking?

Water and Energy: How do different development patterns influence levels of water and energy use?

Air Quality:  How does the mix of buildings and travel behavior of each scenario influence carbon emissions and other pollutants?

Affordability: How does the mix of housing address affordability? Are residents at risk of being displaced?

Travel Behavior: What are the differences in travel behavior that result from different district-level scenario development patterns? How do different development patterns at the city or regional-level influence household-based travel behaviors? 

Public Health: How do changes in walk trips across scenarios result in changes to health?  What are the public health implications of each scenarios travel behavior?

Transportation Safety: How do changes to scenarios, and the associated changes to travel behavior, influence transportation safety?
