Planning

The Planning Department guides the development and long-term growth of the City. It does this by administering the Comprehensive Plan, identifying and preparing amendments to development-related City code, conducting other studies and plans, assisting customers with understanding and applying development-related City codes, reviewing and inspecting certain types of permits, and managing the process for and making technical recommendations on planning cases. The Department also manages the City’s Community Development Block Grant (CDBG) and FEMA Community Rating System (CRS) programs, participates in economic development issues and in the administration of the City’s Flood Hazard Prevention ordinance, serves as the City’s historic preservation office, and serves as staff for four boards – Planning Commission, Zoning Commission, Board of Zoning Adjustment, and Olde Towne Preservation District Commission.

Development Regulations & Zoning

Development regulations are located in several sections of the City’s Code of Ordinances, notably Appendix A Zoning and Appendix B Subdivision Regulations. To fully understand the development regulations applicable to a specific property or project, contact a Planner (planningdept@cityofslidell.org or 985-646-4320).

The Code of Ordinances hosted on the Municode website may not reflect the most current legislation adopted by the City Council. Additionally, moratorium authorized by the City Council may be in place. If you are reviewing the Code for proposed development of a property, contact a Planner to ensure you have the most up-to-date regulations.

There are additional requirements in the Olde Towne Preservation District.

NFIP Community Rating System (CRS)

CRS is a voluntary program of the National Flood Insurance Program (NFIP). CRS communities do things that exceed minimum floodplain management requirements. By doing this, communities earn flood insurance premium reductions for their residents.

Slidell has been a CRS community since 1992. Slidell’s current CRS rating is 6. Team Slidell works continuously on CRS activities to maintain and improve the CRS rating.
