Water Quality Standards

Impervious Cover Limit
No citywide impervious cover cap; drainage systems must accommodate design storm flows per City of Abilene Drainage Design Criteria; water supply lake watersheds are a primary concern given semi-arid conditions
On-Site Treatment Required
No
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 City of Abilene Drainage Design Criteria; semi-arid climate with intense thunderstorm events (20–26 in/year) creates flash flood risk
Turbidity Standard
No numeric NTU limit; discharges must comply with TCEQ TXR150000 and not degrade Hubbard Creek Reservoir, Lake Fort Phantom Hill, or Kirby Lake water quality

Local SWPPP / Drainage Plan

Local Plan Required
Yes
Plan Name
SWPPP per TCEQ TXR150000; drainage report required for local permit
PE Stamp Required
Yes
Drainage study prepared by a Texas PE required for grading permits. Abilene is a regional service center for West-Central Texas with military (Dyess AFB), healthcare, and educational institutions (Abilene Christian University, Hardin-Simmons, McMurry). Water supply is a chronic concern in this semi-arid region — enhanced BMPs to protect water supply lakes are advisable for projects in contributing watersheds.

Local Inspection Requirements

Requirements
City of Abilene Development Services inspects grading permits at rough grading and final stabilization.
Inspector Qualification
No city-specific certification required beyond TCEQ SWPPP requirements

Special Overlay Zones

Water Supply Lake Watersheds
Trigger: Development in the contributing watersheds to Lake Fort Phantom Hill, Kirby Lake, or Hubbard Creek Reservoir (water supply sources for Abilene)
Restriction: Enhanced water quality BMPs required to protect drinking water supply; coordinate with City of Abilene Water Utilities for significant watershed impacts
Dyess Air Force Base Buffer Zone
Trigger: Development near Dyess AFB compatible use zone
Restriction: Coordinate with Dyess AFB for projects in the accident potential zones; base stormwater systems are independent and may affect drainage patterns near the base
FEMA Special Flood Hazard Area
Trigger: Development within FEMA-mapped 100-year floodplain along Cedar Creek and other Abilene waterways
Restriction: Floodplain development permit required from City of Abilene Floodplain Administrator; no net fill without compensatory storage

Jurisdiction Notes

Abilene is the largest city in West-Central Texas, serving as a regional hub for healthcare, education, retail, and military (Dyess AFB). The city's semi-arid climate (~22 in/year rainfall) means water supply is always a concern — the city has historically faced drought and water supply challenges. Three major universities generate modest but consistent construction activity. The area is in tornado alley — spring severe weather season can bring both tornadoes and intense rainfall within hours. Wind erosion during site disturbance is a concern in this open terrain environment.

Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
Disclaimer: This information is provided for general reference only. Always verify requirements directly with City of Abilene Development Services and the agency website before beginning construction.
