Water Quality Standards

Impervious Cover Limit
No citywide impervious cover cap; drainage infrastructure must convey design storm flows
On-Site Treatment Required
Yes
Detention Required
Yes
Detention Standard
Detention required to limit post-development peak flows to pre-development levels for 2-, 10-, and 100-year storms per El Paso Stormwater Management and Design Manual
Turbidity Standard
No numeric NTU limit in local ordinance; discharges must comply with TCEQ TXR150000 and not violate Rio Grande water quality standards

Local SWPPP / Drainage Plan

Local Plan Required
Yes
Plan Name
Stormwater Pollution Prevention Plan (SWPPP) — aligned with TCEQ TXR150000; local ESC plan as part of grading permit
PE Stamp Required
Yes
Drainage report stamped by a Texas PE required for projects disturbing ≥ 1 acre. El Paso's arid climate produces intense short-duration storms; BMPs must account for high sediment loads from desert soils. City may require enhanced inlet protection given wind-blown sediment.

Local Inspection Requirements

Requirements
City of El Paso DSD inspects grading permits independently of TCEQ. Inspections required at key milestones: rough grading, drainage structure installation, final stabilization. Complaint-driven inspections also conducted.
Inspector Qualification
No city-specific certification beyond TCEQ requirements; contractor responsible for SWPPP implementation

Restriction: FEMA floodplain development permit required; finished floor elevations must meet BFE requirements; LOMA/LOMR may be required
Desert Arroyo / Wash Corridors
Trigger: Development adjacent to or crossing ephemeral desert washes and arroyos
Restriction: Setbacks required; culvert crossings must be sized for 100-year flow; erosion protection of channel banks required

Design Manual

Manual Name
El Paso Stormwater Management and Design Manual

Jurisdiction Notes

El Paso's arid climate (≈8 in/year rainfall) produces intense monsoonal thunderstorms July–September capable of generating significant flash flooding. BMPs must address wind erosion as well as water erosion. The Franklin Mountains create rapid runoff concentration. Projects near the Rio Grande require coordination with IBWC and may have additional federal requirements.

Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
