Corpus Christi, TX Environmental Rules: Stormwater Management (2026)

Sec. 14-1001 adopts the city's Storm Water Management Guidance Document for Development Planning and Construction Activities, dated May 28, 1997, and a companion guidance document on flood control project impacts, to keep storm water leaving the city's municipal separate storm sewer system in compliance with its national pollution discharge elimination system permit. Sec. 14-1003(a) requires a site-specific storm water quality management plan for all residential, commercial and industrial development of one acre or more, counting all contiguous land the responsible party owns, not just the disturbed portion; redevelopment of an existing tract is exempt unless it converts more than a quarter acre of porous surface to impervious surface.

The plan must be sealed by a Texas-licensed professional engineer and must identify the outfall point into receiving waters and any environmentally sensitive areas affected. Sec. 14-1005 layers in federal requirements: sites disturbing one acre or more need a full NPDES or TPDES storm water pollution prevention plan filed with Development Services, while sites between a quarter acre and one acre need only a pollution control plan, and sites under a quarter acre and single-lot single-family construction need only comply with the pollution control measures in Sec. 5 inches or more. Appeals of a director's decision go to the city manager within fifteen days under Sec. 14-1007.
