Colorado Special District Boundaries and Contact Information

Thousands of special district boundaries in Colorado, aggregated from local jurisdictions by the Colorado Department of Local Affairs Demography office. The data includes administrative details and geometry, though many boundaries originate from scanned drawings or digitized PDFs. The dataset was last updated in April 2026.

Use Cases

• Map service areas and analyze spatial overlap using the `geometry` column and district `name`.
• Identify district contact points for outreach using `mailCity`, `mailAddress`, `mailZip`, and `mailState`.
• Track district name changes and status over time via the `prevName` and `lgStatus` columns.
• Link district records to external sources using the `lgId` identifier and `url` field.
• Filter districts by type using the `lgTypeId` and `abbrevName` columns.

Strengths

• Contains a `geometry` column for spatial analysis of thousands of districts.
• Includes multiple contact and identifier columns like `mailAddress`, `lgId`, and `url`.

Limitations

• Boundary accuracy is not guaranteed as many were created from scanned drawings or digitized PDFs.
• Sample data and total row count are unavailable for assessing completeness.
