Lewisville, Texas maintains local rules addressing stormwater management, sewer connections and climate resilience measures for new development and existing properties. This guide summarizes the city code, public works requirements, enforcement routes, and practical steps for compliance for residents, contractors and developers, current as of March 2026. It refers to the City of Lewisville municipal code, the city Public Works stormwater program, and applicable state MS4 guidance where the city relies on state permits.[1][2]

Scope and Applicable Rules

Lewisville regulates stormwater discharges, illicit connections, runoff controls for construction, and sewer connections through its Code of Ordinances and departmental rules. Developers must follow grading, detention, and water-quality requirements tied to site planning and building permits. For program implementation the City’s Public Works Engineering and Stormwater divisions manage inspections and compliance.[2]

Contact Public Works early when planning site work to confirm stormwater controls are required.

Compliance Requirements for Common Activities

  • Sewer connections and repairs: licensed plumber permits and city inspection required for private lateral connections; refer to building permit procedures for submission and inspection requirements.[2]
  • Illicit discharge reporting: illegal dumping, sanitary or industrial discharges to storm drains must be reported immediately to Public Works; sampling and corrective measures may be ordered.[2]
Report spills or illicit discharges to the city right away to limit liability and environmental harm.

How-To

  2. Obtain required permits: submit grading, drainage, and building permit applications to Development Services; attach erosion control plans and calculations per submittal checklist.[2]
  3. Install controls: implement silt fences, sediment basins, and permanent treatment measures as approved in permits and maintain them until stable vegetation or final controls are in place.
  4. Schedule inspections: request inspections through the city portal or phone; correct deficiencies in the timeframe set by the inspector to avoid enforcement.
  5. Appeal or request variance: if denied, follow the City Code appeal route or request a variance with supporting documentation to the designated review body; confirm time limits with the department.[1]
Keep documented maintenance and inspection records to demonstrate compliance during reviews or disputes.
