Sunnyvale is a Dallas County town on the eastern side of the county. Its own recreation resources include Town Center Park, which has a reservable pavilion. The town maintains a separate municipal government despite being closely connected to the larger eastern Dallas urban area.

### Places to know

**Town Center Park.** A municipal recreation space with a pavilion available through the town’s reservation process.

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

- Confirm Sunnyvale city limits and the lot’s subdivision restrictions before using a neighboring city’s permit information or assuming a planned improvement is allowed.
- 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).
