Planning commission denies two large rezoning requests after hours of testimony on traffic, drainage and flood risk

The St. Tammany Parish Planning and Zoning Commission denied two rezoning applications on June 1 after extensive public comment and debate over traffic, drainage and flood risk.

The first decision came on a request to rezone about 264.35 acres near U.S. 190 and LA 1077 from a mix of R‑1/R‑2/NC2 to S‑1 and S‑2 suburban residential zoning. The project team said the concept plan reduces density from prior filings, adds large perimeter buffers and proposes “a 100‑year reduction, a 25% reduction on a 200‑year storm event” for drainage, but residents and several commissioners said those commitments do not eliminate the underlying infrastructure shortfalls. The commission voted to deny the rezoning.

Why it mattered: Hundreds of nearby residents and multiple speakers told the commission that LA‑1077 and adjacent roadways already carry heavy traffic and that adding several hundred more homes would strain roads, schools, emergency services and drainage. “It was a freaking nightmare,” one resident said during public comment, summarizing a common line of concern about traffic and flooding. Several speakers also pointed to the parish’s history of flood claims and the difficulty of retrofitting major drainage fixes after subdivisions are built.

What proponents said: The petitioner’s representative told the commission the proposal is more conservative than last year’s filing, keeps substantial buffers along existing homes and would phase buildout over many years; they also said the project would generate impact fees and could contribute to corridor improvements through cooperative agreements. The applicant said the plan would use ponds and other measures to exceed current code for stormwater control.

What opponents said: Neighbors and community groups argued the area lacks adequate road capacity and that drainage and flood risks have not been resolved. A representative who said he is a certified floodplain manager noted the area can experience complex overflow from basin systems and questioned whether proposed stormwater measures would perform as modeled during extreme events.

Commission deliberations: Commissioners weighed staff findings that the request is broadly consistent with nearby residential development and the parish’s 2040 plan against strong local opposition and concerns about cumulative impacts. Commissioner Narcisse moved to deny the rezoning; the motion carried.

A second, separate rezoning for 31.51 acres nearby — a request to rezone to S‑2 suburban residential for roughly 91 lots — drew similar testimony and was also denied. Supporters said the smaller site is consistent with surrounding subdivisions and could provide lots for local builders; opponents said the incremental addition of units still worsens congestion and flood risk in the corridor. After rebuttals from the petitioner and builders emphasizing the need for additional lots, Commissioner Martino and others expressed concern about setting a precedent of converting low‑density parcels to much higher density in an already strained portion of the parish.

What happens next: Both denials are recommendations to the Parish Council appellate process; affected parties may appeal to the council. Several speakers and commissioners suggested additional community meetings to explore alternatives, and petitioners said they may return with modified applications or conditional‑use requests that narrow uses or address specific engineering concerns.

The commission’s actions underscore the tension between demand for housing and local infrastructure limits in parts of St. Tammany Parish, with commissioners signaling that developers must resolve demonstrated traffic and drainage solutions before denser zoning will be approved.
