Should local governments prioritize easing property development restrictions in flood-prone areas?

In June 2026, the city of Wichita Falls commissioned a $177,535.69 flood mitigation study that utilized lidar-based 3D modeling. Preliminary findings suggest current FEMA floodplain maps overstate the flood risk on the city's east side.

Why it matters

The study aims to reconcile outdated municipal mapping with current topographical data to reduce regulatory permit burdens for property owners. If validated, the findings could shift floodplain boundaries by three to four blocks.

The city spent $177,535.69 on a study using lidar-based 3D modeling to analyze topography, identifying discrepancies in floodplain size compared to current regulatory standards.

The players

Wichita Falls

The city government that authorized the lidar-based topographical study to update local flood risk assessments.

HDR Engineering

An engineering firm hired by the city to conduct the flood mitigation study and perform 3D terrain modeling.

FEMA

The federal agency responsible for maintaining flood hazard maps and reviewing municipal requests for map revisions.

The details

The analysis uses lidar — a remote sensing method that uses light pulses from lasers to measure variable distances to the earth — to create high-resolution 3D models of the local terrain. These models allow engineers to more accurately simulate water flow and accumulation patterns than the legacy data currently used for FEMA floodplain boundaries. The city intends to submit these technical findings for a formal map revision, which initiates a process to verify that the proposed changes meet federal flood risk criteria.

Timeline

  1. June 2026: The city contracted HDR Engineering to perform the flood mitigation study.

  2. January 2028: Potential timeline for the implementation of a revised floodplain map.

The Tech Race

This study aligns with the National Flood Insurance Program's map revision process, which requires municipalities to submit superior data to trigger boundary adjustments. It marks a push to move beyond legacy mapping toward high-fidelity lidar assessments of urban flood risk.

Homeowners on the east side of Wichita Falls currently subject to development permit requirements may see these regulations lifted if the boundary shift is approved. The city expects a 90-day review period once results are officially submitted to federal authorities.

The takeaway

The city is currently working to align its regulatory boundaries with high-precision lidar measurements to simplify property development. Residents should track the formal submission of these findings to FEMA, which could lead to finalized map changes by early 2028.
