Amarillo's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In Amarillo, Texas, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Erosion Control

Amarillo requires all construction sites to implement erosion and sediment controls to prevent soil and contaminants from entering the city's stormwater system. Sites disturbing one or more acres must obtain a state TPDES Construction General Permit and submit a Stormwater Pollution Prevention Plan.

Key details: State permit trigger: 1+ acres disturbed (TPDES TXR150000). Required document: Stormwater Pollution Prevention Plan (SWP3). City code chapter: Ch. 18-4 – Drainage Utility. Enforcer: Amarillo Stormwater Quality (806-342-1528).

Non-compliance may result in stop-work orders, required corrective BMPs, TCEQ enforcement, and civil penalties up to $25,000 per day under Texas Water Code.

Amarillo is more permissive than most cities when it comes to erosion control. That said, there are still limits.

Flood Elevation Requirements

New and substantially improved residential structures in Amarillo's FEMA Special Flood Hazard Areas must have the lowest floor, including any basement, elevated to at least one foot above the Base Flood Elevation, certified by a registered engineer, architect, or land surveyor.

Key details: Freeboard: 1 foot above BFE. Governing section: Amarillo Code § 4-8-8(d)(1). Enforcer: City Engineer / Floodplain Admin. Certification: Engineer, architect, or surveyor. Shallow AO/AH zones: BFE or 2 feet minimum.

Building without a floodplain development permit, or with a lowest floor below one foot over the Base Flood Elevation, blocks final inspection and the building permit; the City Engineer withholds approval until certified compliance is provided.

Stormwater Management

Amarillo's Municipal Separate Storm Sewer System ordinance bans discharging any pollutant, including oily sheens, corrosive stormwater below pH 5.5, and noxious substances, into city storm drains under Code of Ordinances Sec. 18-3-94. The Director of Utilities enforces the rule with escalating notices, compliance orders, and civil penalties from $100 to $1,000 per violation per day under Sec. 18-3-101.

Key details: Governing law: Code of Ordinances Ch. 18-3, Art. V (Storm Sewers). Enforcing agency: Director of Utilities / Stormwater Coordinator. Discharge ban: Pollutants, oil sheens, pH below 5.5 prohibited. Civil penalty: $100 to $1,000 per violation per day. Cure period: 10 business days after Notice of Violation.

Violating Sec. 18-3-94's discharge prohibitions triggers a written Notice of Violation with a 10-business-day cure period; noncompliance escalates to a compliance order and then a Red Tag Order that halts city permits, inspections, and occupancy approvals at the site. Civil penalties run $100 to $1,000 per violation per day under Sec. 18-3-101(a)(3), escalating for repeat offenders. The Director can also suspend water, sewer, or MS4 access without notice for discharges threatening health or the environment; the resulting condition is deemed a public nuisance subject to summary abatement at the violator's expense.

This is one of the stricter rules in Amarillo's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

The Bottom Line

Amarillo's environmental rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Amarillo is broadly strict or permissive.
