Brownsville's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In Brownsville, Texas, there are 5 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.

Grading & Drainage

Excavation and grading in Brownsville run under a model code adopted by reference in its 1975 edition, enforced by the city engineer and building official. Owners on unpaved streets install driveway culverts at their own cost.

Key details: Adopted code: Standard Excavation and Grading Code, 1975. Enforcers: City engineer and building official. Culvert duty: Owner pays; city engineer specifies. Continuing violation: Each ten days a separate offense. Design manuals: City drainage reports and criteria.

Grading violations are misdemeanors under section 18-718, with each ten days a prohibited condition stands counting as a separate offense. Noncompliant driveway crossings must be removed or corrected after ten days' written notice.

Stormwater Management

Brownsville runs a TPDES-permitted municipal storm sewer system with a broad illicit discharge article, and requires engineer-signed stormwater management plans, maintenance easements and recorded covenants for subdivision and site plan development.

Key details: Permit: TPDES MS4; Ord. No. 2013-1576. Exemption threshold: Under one acre disturbed. Performance bond: Construction cost plus twenty-five percent. Maintenance: Covenant recorded with County Clerk. Inspections: Annual minimum for each facility.

Each day and each section is a separate offense under section 46-293, and no culpable mental state is required. Fines follow section 1-13, and the city attorney may seek an injunction.

Coastal Development

Brownsville sits about twenty miles inland of the Gulf and holds no public beach. The Texas Coastal Management Program boundary starts at the city's International Toll Bridge, so coastal zone consistency review reaches much of Brownsville.

Key details: Gulf beach jurisdiction: None; Cameron County administers. Coastal zone boundary: Begins at International Toll Bridge. Floodplain maps: Cameron County FIRM, February 16, 2018. Windstorm: TWIA first-tier; WPI-8 certificate. Floodplain permit: Required for all development.

Building in a special flood hazard area without a floodplain development permit is a misdemeanor carrying a fine up to $500 per violation, plus all case costs, under section 308-148.

Erosion Control

Brownsville has no dedicated erosion control chapter. Sediment leaving a site is controlled instead through the storm water pollution prevention article, the development code's stormwater plan requirement, and the state construction general permit.

Key details: Governing section: Code § 46-253(b), sediment discharge. Plan threshold: One acre of land disturbance. State permit: TCEQ TPDES CGP TXR150000. Plan preparer: Texas-licensed professional engineer. Applies in ETJ: Yes, plus city limits.

Each day and each section violated is a separate offense under section 46-293, punished by fine under section 1-13, and the city attorney may petition a court for an injunction.

Flood Zones

Brownsville participates in FEMA's National Flood Insurance Program and regulates development in flood zones. The city faces significant flood risk from hurricanes, tropical storms, and Rio Grande flooding.

Key details: NFIP: Brownsville participates. Flood Sources: Hurricanes, tropical storms, Rio Grande. Elevation: Lowest floor at or above BFE. Coverage: Large portions of city in SFHA.

Building in flood zones without permits and elevation certificates results in fines, insurance issues, and increased flood insurance rates.

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

The Bottom Line

Brownsville'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 Brownsville is broadly strict or permissive.

Keep in mind that Brownsville can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
