Jurisdiction Notes

Pflugerville is a fast-growing Austin suburb in northern Travis County/southern Williamson County, experiencing significant residential and commercial development. Major employers including Apple and Samsung have facilities nearby, spurring growth. The city straddles two counties, which adds permitting complexity for projects near the county line. Gilleland Creek has been a persistent flooding concern and has received significant engineering study and improvement investment.

Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
