Drainage study prepared by a Texas PE required for grading permits. Leander is one of the fastest-growing cities in Texas, with large master-planned community development underway. Edwards Aquifer recharge and contributing zones affect portions of the city. Williamson County drainage districts coordinate on regional channel infrastructure. Brushy Creek Regional Utility Authority (BCRUA) may have additional requirements for projects in the Brushy Creek watershed.
Local Inspection Requirements
- Requirements
- City of Leander Development Services inspects grading permits at rough grading and final stabilization.

Restriction: Barton Springs/Edwards Aquifer Conservation District (BSEACD) rules apply; impervious cover limits and recharge-protection BMPs required; avoid direct discharge to sinkholes, caves, or karst features
Brushy Creek Watershed
Trigger: Development draining to Brushy Creek and its tributaries
Restriction: Brushy Creek Regional Utility Authority (BCRUA) manages regional infrastructure; coordinate with BCRUA and Williamson County for significant drainage impacts; Brushy Creek has experienced historical flooding

Jurisdiction Notes
Leander is among the fastest-growing cities in Texas and the nation, driven by Austin tech-sector overflow growth and high-capacity transit access (MetroRail). The city is developing large master-planned communities with significant construction activity. Edwards Aquifer recharge and contributing zone regulations add a layer of water quality complexity not found in most Texas cities. Williamson County's rapid growth means regional drainage infrastructure is frequently planned and built. Karst topography requires careful BMP selection to avoid direct aquifer injection.
Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
