Civil Engineering in Mississippi: what governs your project

Construction stormwater discharges are regulated by the Mississippi Department of Environmental Quality (MDEQ) through its NPDES construction general permit. Driveway connections to state highways require permits from the Mississippi Department of Transportation. Coastal projects face additional wetland and coastal-zone review, and Mississippi River floodplain development is governed by levee board requirements and local floodplain ordinances.

Permitting & plan check

Building permits, plan review, and inspections are handled by city and county building departments under locally adopted codes based on the IBC family. Mississippi has no single statewide commercial plan review office; authority sits with local jurisdictions. Early confirmation of the locally adopted code edition and amendments is standard practice.

Good to know

• The Yazoo clay underlying much of central Mississippi is famously expansive, and designing foundations and slabs for its shrink-swell behavior is a defining local practice.
• Mississippi's Gulf Coast rebuilding after Hurricane Katrina drove lasting changes in wind design, flood elevation, and building code enforcement statewide.
• Large areas of the Mississippi Delta sit behind the Mississippi River levee system, making floodplain regulation central to site development there.
