## Data quality

- The exact facility is identified in third-party facility directories as Lumen Austin 1 at 4207 Smith School Road; the mapped OSM-associated address is 4209 Smith School Road, so the 4207/4209 discrepancy should be retained rather than resolved by assumption.
- Austin's official zoning record identifies 4207 Smith School Road as Lot 1, Burleson Office Subdivision, approximately 6.520 acres, with Warehouse Limited Office zoning and a 2,000-trip-per-day conditional overlay.
- The separate Switch/Data Foundry expansion reported at 4100 Smith School Road is nearby but is not treated as evidence about Lumen Austin 1 at 4207/4209 Smith School Road.
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
