Sacramento County Flexible Mitigation Strategy

> View Presentation Slides

Description

Like many jurisdictions, Sacramento County has historically conditioned development to implement roadway improvements and mitigations tied to a specific number of dwelling units. While this approach has been effective on smaller scale developments, it does not always dictate the appropriate timing and location of improvements for large Specific Plans. The County has developed a flexible mitigation strategy attuned to the actual location of development. For any amount of phased development that might be implemented, a spreadsheet “dynamic implementation tool” estimates the trip assignment and determines if the growth would trigger an impact, based on significance thresholds. Calculations in the tool are based on outputs from the SACSIM model used for the traffic impact analysis. The model tracks the origin and destination of each trip end by traffic analysis zones, which are aggregated to larger districts. Select link analysis determines the fair share allocation of volume growth to each district. Based on the amount of development assumed and entered into the tool by district, VMT-based trip rates are applied to estimate volume increases through each segment and intersection. With this information, a nexus can be established between a phasing concept and infrastructure needs without the costly and time-consuming process of rerunning the demand model. This approach gives developers flexibility with project phasing and optimization, while ensuring that deficiencies are expeditiously addressed. The County has the tools to proactively monitor and manage the transportation network, ensuring transportation funds are spent where they are needed.

Description

The presentation will:

  • Unpack a 4-step methodology for developing defensible estimates of existing and future travel demand, to keep projects moving forward despite unusual travel patterns during COVID-19
  • Provide case studies showing where and how it’s recently been applied
  • Discuss what the next few weeks and months may hold for traffic counts
  • Answer questions from attendees through a Q&A facilitated by Alex Garbier
