The rule that already applies, and already has a per-day penalty

Set the draft aside for a moment. What most affects a Louisiana subdivision association today is the existing code text the draft carries forward — ULDC §17-5014, adopted in 2007 and amended in 2009:

“A. Drainage servitudes are dedicated to the Parish for the exclusive purpose of maintaining adequate storm water drainage. Any encroachment into a dedicated servitude is prohibited.”

“C. If the landowner fails to remove an encroachment within the ten-day period, they shall be assessed a penalty of $100.00 per day until the encroachment is removed and verified by the Department of Public Works and/or the appropriate drainage district.”

Ten days to remove, then $100 a day. A shed, a fence line, a raised bed or a slab that sits in a dedicated drainage servitude is a live exposure — and in a community where the architectural committee approved the improvement, the board has a problem of its own making.

The same section also draws the line the draft is pushing on:

“9. Stormwater ponds/lakes require a 30-foot servitude from the inlet to the outlet of the pond/lake. Privately owned and maintained stormwater ponds/lakes shall be exempt from this 30-foot servitude requirement.”

Privately owned and maintained ponds are treated differently from dedicated ones. That distinction is the pivot on which the whole maintenance question turns.²

Why the direction of travel matters to a board

Because if rear-yard drainage in a major subdivision becomes privately owned and maintained, somebody has to own and maintain it, and in a Louisiana planned community that somebody is usually the association.

Under R.S. 9:1141.33 the association is “responsible for maintenance, repair, and replacement of the common areas and limited common areas” — the section the Second Circuit applied in Horton in July 2026. A drainage pipe network in the rear yards of a subdivision, privately owned, is a reserve component with a replacement cycle. So is a detention pond designed to a fifty-year storm.

And Louisiana has no reserve-study mandate to force anyone to price it. What it has is a disclosure duty: R.S. 9:1141.34(A)(1) requires the budget summary to include “any reserves, and a statement of the basis on which any reserves are calculated and funded.” A board that inherits privately maintained drainage and does not add it to that statement is disclosing less than the statute contemplates.

The parallel exposure that arrived by statute this year

While parishes are pushing drainage private, the Legislature has pushed water and sewer collection the other way. Act 99 of 2025 gave municipalities a recorded privilege against master-metered multifamily residential property of more than four dwelling units for unpaid water or sewer charges, and Act 575 of 2026, effective August 1, 2026, extended it: “Parishes, municipalities, sewerage districts, and waterworks districts shall have a privilege against a multifamily residential property for the amount of any unpaid service charge or user fee for sewage disposal or water system services that they provide.”

So a Louisiana association holding a master utility account now faces a recorded privilege for arrears, while separately being pushed toward owning more of the infrastructure.

What a board can do

• Get the recorded plat and identify every drainage servitude. It is the document that decides whether the parish maintains it or you do.
• Add servitude verification to the architectural review checklist. An approval that puts a fence in a dedicated servitude buys the owner a ten-day notice and the board an argument.
• Treat an association-owned pond as a reserve component. It has a dredging cycle, a structure and an outfall.
• Watch your own parish, not this one. Ascension is the draft we could read; nothing suggests it is the only parish moving.

What to watch next

Whether the Ascension ordinance is adopted, and with what number and date — both unverified. A reported October 2025 Planning Commission recommendation for five-year inspections of privately owned stormwater and floodplain mitigation facilities, with long-term accountability to be determined within 120 days of adoption, comes from local reporting we could not verify and we do not publish it as fact. And no 2025 or 2026 Jefferson Parish, East Baton Rouge, St. Tammany or Livingston Parish ordinance shifting detention-pond maintenance onto an association surfaced in our search — which is not the same as none existing.
