Housing & Infrastructure in Key Colony Beach
With 63% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
The lead that enters tap water in older homes often comes not from the municipal supply but from the home's own plumbing — from solder used in copper joints before the 1986 federal ban, or from lead pipes installed before 1970. In Key Colony Beach, where the median build year is 1970, these older materials are widespread. More than half the residential stock predates the 1986 solder ban, and a significant fraction predates 1970 as well. For residents in those homes, the city-wide water quality picture is a less relevant frame than the specific materials inside their own walls and under their own street.
Over half of homes in Key Colony Beach were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Key Colony Beach Homeowners
Within the Key Colony Beach market, estimated remediation claims a small portion of typical property equity — the financial burden is proportionally low.
Remediation costs in Key Colony Beach are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 147% above the Florida average.
Lead Exposure Risk for Children in Key Colony Beach
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Wherever 63% of local housing was built before solder rules changed — as is the case in Key Colony Beach — a faucet-level sample closes the gap that aggregate utility data cannot.

Flood & Climate Risk in Key Colony Beach
Measured against the full NFIP dataset, Key Colony Beach's flood record stands out: 926 claims accumulated over decades and 100% of ZIP codes inside FEMA-designated boundaries add up to a high-exposure profile where water infrastructure has faced recurrent stress.
Key Colony Beach has a significant flood history with 926 FEMA flood insurance claims on record, averaging $42,514 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,400</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
