San Antonio's UDC requires property developers to manage all stormwater flowing through their property, including drainage from upstream development. The Storm Water Design Criteria Manual (Jan 2016) governs design standards. The Edwards Aquifer Protection Ordinance (Chapter 34, Div. 6) limits impervious cover to 15% for residential development on the Recharge Zone and prohibits impervious cover in floodplain buffer zones.
San Antonio regulates grading and drainage through building and engineering codes. Grading permits required for excavation or fill over specified thresholds, typically 50 to 100 cubic yards. Site grading must direct drainage away from structures and not adversely affect neighboring properties. Drainage swales, French drains, and catch basins may be required. Retaining walls over 4 feet need engineering and separate permits. Compaction testing required for structural fill. Final grade must match approved plans. Property owners responsible for maintaining drainage facilities on their land.
Unpermitted grading: stop-work order and fines $250 to $2,500. Redirecting drainage to neighbors: corrective action required. Slope failure from improper grading: liability and remediation costs.
