What to plan for in Slidell
- Hurricanes (very high): Hurricanes can mean a week without power. A standby generator on natural gas or propane, or a battery with solar, beats a stack of gas cans; check flood height before you site equipment.
- Lightning (relatively high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- River and heavy-rain flooding (relatively high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
Permits and approvals in Slidell

- No official City of Slidell permit page could be reached, so this points to the parish government site as the best official starting point. Check with the city or parish permits office before you start.
