Date: April 20, 2026
I am writing as a citizen of Thibodaux to respectfully request careful review and due diligence regarding the referenced agenda item involving the division of property and associated land use changes within the Rienzi Canal drainage basin.
This request is not based on opposition to development or environmental mitigation in principle, but on a concern that decisions of this permanence require full validation, transparency, and alignment with existing code and long-term system performance.
I. Legal and Governance Considerations
The role of the City is not merely to approve proposals, but to ensure that any action taken is:
-
Within clearly defined legal authority
-
Supported by transparent, complete, and verifiable data
-
Protective of the long-term public interest
Where a proposal introduces permanent land-use constraints within a critical drainage corridor, the need for careful validation and documentation is elevated.
II. Zoning and Code Compliance Considerations
A threshold question that should be clearly addressed prior to any approval is whether the proposed mitigation use is explicitly defined and permitted under the City’s current zoning and land use ordinances.
Based on currently available information, it is not evident that a wetlands mitigation or mitigation banking use is clearly defined within the applicable zoning classifications governing this property.
If such use is not clearly defined, it raises important considerations:
-
Whether the proposed use aligns with the intent of the existing zoning classification
-
Whether additional definition or ordinance clarification may be appropriate
-
Whether the current framework fully addresses the long-term implications of this type of use
City ordinances are intended to provide clarity, consistency, and protection for both the public and the integrity of the planning process.
If the proposed mitigation use does not clearly fit within existing code, it may be appropriate to:
-
Establish a defined zoning classification or ordinance provision specific to mitigation use
-
Clarify operational expectations and performance standards
-
Provide an opportunity for full review and understanding before such use is approved
Approval of a use not clearly defined within the existing code framework may expose the City to challenges on the basis of improper or inconsistent application of its own ordinances.
III. Permanent Constraint and System Considerations
The proposal appears to establish a fixed right-of-way and mitigation footprint within a basin that has experienced drainage challenges, including narrowed canal sections and known flow constraints.
Once established, this type of configuration becomes difficult to modify without significant cost and disruption.
For that reason, it is important that there is clear demonstration that:
-
The system has adequate capacity under current and projected conditions
-
Maintenance access is sufficient to support long-term performance
At present, it is not clear that this information has been fully presented or reviewed in a public setting.
IV. Information and Review Considerations
Prior to any approval, it would be beneficial for the following information to be clearly presented and made available for review:
-
Hydrology and hydraulic modeling for the Rienzi Canal system
-
The 2018 Duplantis Design Group study and any subsequent updates
-
Design assumptions, including storm events and runoff calculations
-
Capacity analysis of constrained sections
-
Existing and proposed right-of-way agreements
-
Identification of system pinch points and overall system performance
-
Maintenance responsibility and long-term cost considerations
V. Pre-Approval Due Diligence Considerations
To assist in a clear and responsible evaluation of this proposal, the following elements represent a practical framework for review prior to any approval:
- Confirmation that right-of-way widths support long-term maintenance
- Understanding of existing right-of-way conditions and constraints
- Updated hydrology validating system performance
- Capacity evaluation at known constrained areas
- Identification and impact of all pinch points
- Clear definition of mitigation and impoundment function
- Practicality of long-term maintenance access
- Defined responsibility for ongoing maintenance
- Understanding of long-term cost implications
- Public availability of all supporting engineering information
VI. Transparency and Public Understanding
Given the long-term nature of this decision, it is important that supporting information be fully disclosed and that adequate time is provided for both technical and public review.
This helps ensure that the decision is well understood and supported by those it will ultimately affect.
VII. Long-Term Considerations
If decisions of this type are made without full validation, they can create long-term challenges related to:
-
System performance under stress conditions
-
Maintenance limitations
-
Increased costs over time
-
Potential impacts to surrounding properties
These considerations are not immediate, but they are important to evaluate in advance.
VIII. Request for Consideration
In light of the above, I respectfully ask that the City consider the following prior to any approval:
-
Ensure that all relevant information is fully disclosed
-
Allow sufficient time for technical and public review
-
Confirm alignment with existing zoning or clarify it where needed
-
Demonstrate that the system can perform adequately under current and future conditions
This is a significant decision that will shape the performance and flexibility of a critical drainage system for many years to come.
My intent is not to oppose progress, but to ensure that the decisions made today are fully informed and do not create avoidable challenges for the City and its residents in the future.
Respectfully,
