Local Permit / Authorization
- Permit Required
- Yes
- Permit Name
- Stormwater Construction Permit / Grading and Drainage Permit
- Submit To
- City of Corpus Christi Development Services
- Lead Time
- Plan review 2–6 weeks; drainage study required for projects ≥ 1 acre
- Application Method
- Online via Corpus Christi permitting portal or in-person at Development Services, 2406 Leopard St
- Fee
- Based on project area; contact Development Services for current schedule
Water Quality Standards
- Impervious Cover Limit
- No citywide impervious cover cap; coastal and bay watershed overlay controls apply in sensitive areas
- On-Site Treatment Required
- Yes
- Detention Required
- Yes
- Detention Standard
- Detention required to maintain pre-development peak flows for 2-, 10-, 25-, and 100-year storms per Corpus Christi Drainage Design Manual; low-lying coastal topography requires careful routing analysis
- Turbidity Standard
- No numeric local NTU limit; discharges must comply with TCEQ TXR150000 and not degrade Corpus Christi Bay, Nueces Bay, or receiving water quality standards
Local SWPPP / Drainage Plan
- Local Plan Required
- Yes
- Plan Name
- Stormwater Pollution Prevention Plan (SWPPP) per TCEQ TXR150000; Drainage Report required for local permit
- PE Stamp Required
- Yes
Drainage Report prepared by a Texas PE required for all projects ≥ 1 acre. Coastal proximity means discharges can directly affect bay water quality and seagrass beds — silt fence and inlet protection are minimum requirements. Temporary construction access across FEMA floodways requires separate coordination.
Local Inspection Requirements
- Requirements
- City of Corpus Christi inspects grading permits at rough grading, drainage installation, and final stabilization stages. Hurricane season (June–November) requires heightened BMP maintenance and pre-storm inspections.
- Inspector Qualification
- No city-specific inspector certification beyond TCEQ requirements; PE-of-record responsible for drainage design compliance

Jurisdiction Notes
Corpus Christi's coastal location and flat topography create unique stormwater challenges. The city is in a hurricane-prone area — construction timing relative to hurricane season is an important planning consideration. Padre Island and other barrier island projects have the strictest requirements due to FEMA V-Zone mapping and proximity to the Gulf of Mexico.
Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
