Introduction

In Dallas, Texas, projects in regulated floodplain areas require a floodplain development permit before construction, land alteration, or certain repairs. This guide explains where to apply, which office enforces the rules, typical documentation, and practical steps to secure a permit so your project meets Dallas floodplain regulations and local building codes. Follow the official department procedures and use the contact links below to confirm current forms and timelines.

Where to Apply

Apply through the City of Dallas Development Services division, which manages floodplain review and permitting for land use and building work within mapped flood hazard areas. Current online guidance and contact points are published on the city site[1]. For permit intake, plan review, and building inspection scheduling, use Development Services and Building Inspection permit portals[2].

Start by confirming the property's floodplain status with Development Services.

What the Permit Covers

  • New construction and substantial improvements within a mapped floodplain.
  • Grading, fill placement, and other site work that changes flood flows or storage.
  • Elevation certificates, engineered floodproofing, and drainage plans when required.

Required Documentation and Typical Steps

  • Completed permit application and project drawings (site plan, elevations).
  • Elevation Certificate or flood study prepared by a licensed engineer when required.
  • Permit fees as calculated by Development Services during plan intake.
  • Plan review turnaround and inspection scheduling through the permit portal.
Elevation certificates are commonly required for development in FEMA-mapped zones.

Applications & Forms

The city publishes permit application workflows and intake instructions on the Development Services pages; specific form names, fee schedules, and submittal formats are shown there or provided at application intake[2]. If a dedicated floodplain application form exists it will be listed on the official permit pages; otherwise the general development permit application is used (form name and fee details are not specified on the cited page).

  • Monetary fines: specific fine amounts are not specified on the cited pages.
  • Escalation: first, repeat, or continuing offence procedures and ranges are not specified on the cited pages.
  • Non-monetary sanctions may include stop-work orders, removal or restoration orders, and civil court actions; exact remedies and processes are detailed in city code or enforcement notices when issued.

  • Appeals and review: the process for appeals, variances, or administrative review is handled through the city review channels; time limits for filing appeals are not specified on the cited pages.
If work has already started in a floodplain without a permit, contact Development Services immediately.
