Seis Lagos is a residential community in Collin County around six constructed lakes near Lucas. Its community association and Seis Lagos Utility District are separate organizations. A Lucas or Wylie mailing designation does not, by itself, establish municipal jurisdiction or identify which association and service-district rules apply to the lot.

### Places to know

**Six-lake setting.** The community association identifies the constructed lakes as a central feature of the neighborhood; access is governed by community rules.

### Check at the address, not the town name

- Confirm the lot’s municipal or extraterritorial-jurisdiction status and the applicable association documents.
- Check current utility-district notices and service arrangements directly with the district.
- School attendance zones, flood risk, HOA obligations, utilities and property taxes follow the exact address. Use current records: [TEA school district locator](https://tea.texas.gov/families-and-students/school-district-locator/school-district-locator?ref=tx.co), [FEMA flood maps](https://msc.fema.gov/portal/home?ref=tx.co), [county appraisal districts](https://comptroller.texas.gov/taxes/property-tax/county-directory/?ref=tx.co).
