Data: FEMA National Flood Insurance Program (NFIP), FEMA Hazard Mitigation Last verified: 2026-05-03

With 1896 FEMA flood insurance claims attributed to Lacombe, the flood history here is substantial — each claim represents an actual NFIP payout tied to a documented property loss. Home insurance does not cover flooding; those payouts reached property owners only because they held a dedicated flood policy. Anyone without that coverage at the time of a flood event faces the full cost of damage without insurance reimbursement.

What are FEMA flood zones?

FEMA classifies areas into flood zones based on the probability of flooding. High-risk zones (A and V) have a 1% annual chance of flooding and require flood insurance for federally-backed mortgages. Moderate-risk zones (B/X shaded) have a 0.2% annual chance. Even in low-risk zones, about 25% of all flood claims come from areas outside designated high-risk zones. Lacombe has 1% of ZIP codes in designated flood zones.

How are flood insurance claims calculated?

FEMA tracks every claim filed through the National Flood Insurance Program (NFIP). Claims data includes payouts for building damage and contents loss. High claim counts in an area indicate actual flood events, not just theoretical risk. Lacombe has 1,896 recorded claims — this real-world history is often a better risk indicator than flood zone maps alone.

Understanding Flood Zones

FEMA classifies areas into flood zones based on risk:

Zone	Risk Level	Description
A, AE, AH, AO	High	1% annual chance of flooding (100-year floodplain)
V, VE	Very High	Coastal areas with wave action
B, X (shaded)	Moderate	0.2% annual chance (500-year floodplain)
C, X (unshaded)	Low	Minimal flood risk

Important: Even "low risk" areas experience flooding. Over 40% of NFIP claims come from outside high-risk zones.

How Flooding Affects Drinking Water

Flooding poses direct threats to drinking water quality:

1. Water treatment plant overflow — systems can be overwhelmed, leading to untreated or partially treated water
2. Sewage contamination — floodwater mixes with sewage systems, introducing bacteria and pathogens
3. Agricultural runoff — pesticides, fertilizers, and animal waste enter water supplies
4. Well contamination — private wells are especially vulnerable to floodwater infiltration
5. Infrastructure damage — pipes can break, creating entry points for contaminants

After a flood event, always follow local boil water advisories and avoid using tap water until the all-clear is given.
