Converse, TX Environmental Rules: Grading & Drainage (2026)

Grading and drainage in Converse are regulated through the Subdivision Ordinance, the 2018 International Building Code Appendix J (Grading), and city engineering standards. Significant earth-moving activities, importing or exporting fill, modifying slopes, or altering drainage channels require a grading permit and often an engineered grading plan stamped by a Texas-licensed engineer. Property owners cannot redirect stormwater runoff in ways that cause damage to adjacent properties; Texas common law prohibits unreasonable interference with natural drainage. Positive drainage away from buildings (minimum 5 percent slope for 10 feet) is required under the adopted building codes. Subdivisions and commercial developments must provide engineered drainage studies showing no adverse impact downstream and adequate detention to manage increased runoff. French drains, sump pump discharges, and downspouts cannot be directed onto neighboring lots.
