Tax Measure Dashboard

The Tax Measure Dashboard is a customized extension of the DOT Dashboard platform, created to help agencies like the Napa Valley Transportation Authority (NVTA) clearly communicate how local transportation sales tax dollars are allocated and spent. The result is an interactive, transparent, and data-driven tool that connects funding sources to tangible community outcomes.


Transparency and Accountability in Action

The Tax Measure Dashboard demonstrates how local transportation agencies can deliver full transparency to voters, partner agencies, and board members. Built within the DOT Dashboard framework, this tool tracks the allocation and use of sales tax revenues that fund NVTA’s voter-approved transportation improvements.


Connecting Funding to Outcomes

The dashboard provides an at-a-glance view of how every dollar from NVTA’s Measure T is invested across projects and programs throughout Napa County. Interactive visualizations highlight project categories, local jurisdictions, and progress toward completion, giving users the ability to explore the data behind NVTA’s investments in:

    • Street and road maintenance
    • Active transportation infrastructure
    • Transit capital improvements
    • Climate and safety initiatives

By linking financial data directly to project milestones, the dashboard turns complex budget information into a clear story of community benefit and accountability.


A Model for Transparent Transportation Finance

Tax Measure Dashboard is designed to evolve with each funding cycle. The platform integrates project updates, fiscal reports, and performance metrics to provide continuous insight into the effectiveness of local transportation investments.

The DOT Dashboard framework allows agencies to customize data fields, reporting views, and performance indicators creating a tool that reflects their unique tax measure goals while maintaining fiscal transparency and regulatory compliance.


Technology That Builds Trust

By visualizing the connection between local dollars and local outcomes, NVTA’s Tax Measure Dashboard enhances public trust and supports informed decision-making. It’s a replicable model for agencies managing self-help sales tax measures or other dedicated transportation funding sources.
