What to plan for in Portsmouth
- Coastal flooding (relatively high): Coastal flooding means keeping batteries, generators and electrical panels above flood level; ask a licensed electrician about elevating equipment.
- Ice storms (relatively high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
- River and heavy-rain flooding (relatively moderate): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
