04292026 Assessment Meeting

The Iberia Parish Government held an assessment meeting on June 25, 2026, focused on a comprehensive drainage and flood mitigation study for the T-Bayou watershed following significant flooding events. The discussion centered on the results of a planning-level hydrologic and hydraulic model update, which incorporated recent rainfall data and land cover changes to evaluate various flood control scenarios. The recommended approach involves a combination of upstream detention ponds totaling approximately 25 acres and cleaning of the Far Canal to reduce flood inundation, particularly for 10-year storm events. The estimated cost for these improvements is about $12.5 million, excluding any dredging or modifications at Lake Dory. Challenges noted include right-of-way acquisition for detention ponds, impacts of existing infrastructure such as bridges and sewer lines, and the limitations of flood control given extreme storm events and local subdivision drainage issues. The meeting also highlighted the need for updated parish drainage ordinances and further feasibility studies to optimize design and assess impacts of future development. No formal votes were recorded, but the discussion emphasized next steps toward securing funding and advancing design and construction phases.
