St. Louis Chevalier

What Chevalier Does

  • Unifies city activity into a single operational view (parcel, corridor, program).
  • Lets you see what changed over time with timeline-based navigation.
  • Generates decision-ready summaries and exportable briefings for internal review.
  • Provides rapid cross-jurisdictional context linking between St. Louis and Jefferson City for executive review.
  • Supports role-scoped access for controlled distribution.

Chevalier is an intelligence overlay for high-stakes decisions. It is not a system of record.

Cities are executing capital, regulatory, and programmatic activity across more systems and jurisdictions than legacy tools were designed to reconcile. Decision risk increasingly comes from fragmented timing, delayed signals, and misaligned execution across local and state boundaries. Chevalier compresses review time by presenting what is changing, where delivery is stalling, and where intervention may be required—early enough for executive review.

Use constraints
Chevalier provides informational context and linkage across records. It is not a system of record and must not be used as the sole basis for legal, compliance, eligibility, enforcement, underwriting, or investment decisions. Users must independently verify source records and apply required redactions and statutory restrictions (including public-records/Sunshine materials). Do not submit unnecessary personal data or restricted categories (e.g., SSNs, financial account numbers, health data, minors, sealed/expunged records, law-enforcement restricted datasets) unless explicitly authorized in writing. Not for FCRA-like uses (credit, housing, employment, insurance).

A simulation-grade 3D operational environment designed for parcel-level context, longitudinal monitoring, and executive review. This is an operational interface—not a reporting portal.
