Kenner, LA Environmental Rules: Erosion Control (2026)

Kenner regulates construction-site erosion through its Stormwater Management article, Article X of the Unified Development Code, rather than a stand-alone erosion ordinance. Section 10.04(a) sets the applicability trigger: any new development or redevelopment disturbing seven thousand square feet or more of impervious surface, or covering one acre or more, must submit a stormwater management plan to the Director of the Department of Inspections and Code Enforcement, who approves it in consultation with a Louisiana-licensed landscape architect or civil engineer before a building permit is issued.

Single-family, two-family, and multifamily developments of five units or fewer are exempt from the plan requirement itself but must still comply with applicable federal, state, and local stormwater rules. Section 10.05(a) sets the technical erosion-control performance standards: on-site management must first rely on detention and infiltration through pervious paving, open vegetated areas, and green or blue roofs; additional runoff must be detained, stored, infiltrated, or filtered through Best Management Practices; infiltration practices must reduce runoff volume increases and stabilize subsoils; and every stormwater facility must be designed with an emergency overflow system and a non-erosive velocity of flow along its length and at any outfall, so that discharge does not cause downstream flooding or channel erosion.

Section 10.02 backs the whole article with a hard enforcement stop: no certificate of occupancy may issue for a covered lot until every stormwater requirement is met, and before occupancy a licensed engineer or landscape architect must certify by affidavit that the approved measures were actually installed.
