Land Use and Zoning Texas 4 Minutes Read · published February 09, 2026 Flag of Texas

Arlington, Texas maintains local rules and permitting requirements for activities in mapped floodplains and wetlands to reduce risk to people and property, and to comply with the National Flood Insurance Program. This guide summarizes the city departments, key obligations for landowners and developers, enforcement pathways, and practical mitigation steps for compliance and risk reduction. It is aimed at property owners, builders, and consultants planning construction, grading, or restoration in areas affected by flooding or regulated wetland features.

Overview of Floodplain and Wetland Regulations

Arlington regulates development in mapped floodplains through its floodplain management program and by applying standards from the city code and adopted technical manuals. Projects that alter ground elevation, add habitable space, or change drainage patterns commonly trigger review. Wetlands on private property may also be subject to local review where they intersect drainage corridors; federal and state permits can also apply.

Check the city floodplain map early in project planning.

Key local responsibilities include obtaining required permits before work, submitting flood studies or elevation certificates when requested, and meeting building elevation and drainage standards. The City of Arlington Development Services administers building permits and reviews floodplain issues[1]. The municipal code contains the controlling ordinance language for floodplain regulation[2]. Flood insurance mapping and base flood elevations are available via FEMA's map service and are commonly used in local reviews[3].

Common Requirements and Best Practices

  • Submit building and grading permit applications as required by Development Services.
  • Provide elevation certificates or certified flood studies for new structures or substantial improvements.
  • Design site grading and drainage to avoid increasing flood risk to neighboring properties.
  • Use flood-resistant materials and elevate mechanical systems above base flood elevation where applicable.
Early coordination with Development Services speeds approvals and reduces costly redesigns.

Penalties & Enforcement

Enforcement of floodplain and wetland rules in Arlington is carried out through the City of Arlington departments responsible for permitting and code compliance. The municipal code and Development Services set standards and authorize inspections and enforcement actions. Specific fine amounts and civil penalties for violations are not specified on the cited city pages; see the cited municipal code and department pages for controlling authority and procedures[2][1].

  • Enforcer: City of Arlington Development Services and Code Compliance divisions perform plan review, inspections, and enforcement.
  • Orders: The city may issue stop-work orders, corrective orders, or require restoration to pre-existing conditions.
  • Fines: Monetary fines or civil penalties are handled under the municipal code; specific amounts are not specified on the cited pages.
  • Repeat or continuing violations: Escalation and per-day continuing penalties are governed by the code and may be applied per incident or per day as authorized; exact ranges are not specified on the cited pages.
  • Court action and liens: The city may pursue abatement through court or recover costs; consult the municipal code for procedure and timelines.
If you receive a stop-work order, contact Development Services immediately to understand required corrective actions.

Applications & Forms

The city processes floodplain-related reviews through the Development Services permit system; specific floodplain permit forms and fee schedules are published on the Development Services permits and building pages when available. Where the city requires additional technical submittals (elevation certificates, flood studies), the exact form names or numbers are not specified on the cited public pages; applicants should contact Development Services for current submittal checklists and fee information[1][2].

Action Steps for Property Owners and Developers

  • Confirm floodplain status using FEMA maps and city resources early in project planning.
  • Request pre-application review or a meeting with Development Services to identify required studies and permits.
  • Hire qualified engineers to prepare flood studies, drainage plans, and elevation certificates when required.
  • Budget for mitigation measures such as elevation, flood vents, or resilient materials.
  • Report suspected unlawful filling, alteration, or violation to Code Compliance via the city complaint page.
Documented elevation certificates help with insurance and resale disclosure.
