Colliers partnered with the city of Slidell for a redevelopment concept

Slidell, LA., January 22, 2026 – Colliers is pleased to release its published comprehensive report outlining insights into the redevelopment potential of the Northshore Square Mall site in Slidell. Commissioned by the City of Slidell in partnership with the St. Tammany Economic Development Corporation (STEDC), the report identifies strategies to repurpose the property in ways that stimulate economic growth, diversify the tax base and create quality jobs for the region. The feasibility report for the redevelopment was orchestrated by Colliers’ Chris Abadie, Fiona Sterritt and Jason Boris.

“Our findings highlight significant opportunities to reposition Northshore Square Mall as a catalyst for long-term economic development,” said Chris Abadie, senior vice president at Colliers. “By leveraging public and private-sector insights, we can help the City of Slidell and STEDC make informed decisions that align with market demand and community priorities.”

Key areas in the feasibility report include:
• Event center analysis
• Distribution/Logistics Center analysis
• Light manufacturing analysis
• Logistics and retail hub analysis

“What makes this study especially valuable is that it reflects extensive input from both industry experts and the Slidell community,” said Russell Richardson, President and CEO of St. Tammany Economic Development Corporation. “We’re proud to partner with the City of Slidell, Mayor Fandal, and local stakeholders to help return the Northshore Square Mall site to productive use—ensuring it can once again play a meaningful role in Slidell’s and St. Tammany’s economic future for decades to come.”

Northshore Square Mall is a predominantly vacant retail building generating nominal tax revenue due to a significant lack of business activity. The property spans approximately 54 acres, offering substantial potential for a mix of uses. Its strategic location and existing assets position it as a prime candidate for redevelopment. Property site advantages include excellent interstate exposure and access, proximity to nearby hotels, retailers, and restaurants, a robust economic development environment, a growing population and increased investment in logistics.

“On behalf of the City of Slidell, I want to thank Colliers and STEDC for their partnership on this report,” said Slidell Mayor Randy Fandal. “For a long time, Northshore Square Mall has been both a challenge and an opportunity for our community. This report confirms what we have believed for some time, that this site has strong potential to drive economic growth for Slidell and St. Tammany Parish. Now that we have these results, we can work to attract new investments, create quality jobs, and transform this underused property into an economic hub that supports our families, our businesses, and our future.”
