Housing & Infrastructure in Clarks Hill
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Housing age is a rough starting point, not an answer. Clarks Hill has a median build year of 1995, but any single home may be older or newer than that figure, may have had plumbing replaced, or may still have original fixtures. Lead can also come from a service line or older brass fittings, so a water test or a check of the utility's service line inventory says more about one address than the citywide build year does.
Most homes in Clarks Hill were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Clarks Hill Homeowners
Low tier for Clarks Hill: remediation estimated at up to 1% of what homes are worth.
Estimated remediation costs in Clarks Hill can be compared with local home values. The $600–$2,300 estimated range can be set against the median property value; actual costs vary by home. Home values are 22% above the South Carolina average.
Lead Exposure Risk for Children in Clarks Hill
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
26% of the Clarks Hill housing stock dates from before 1986, the year Congress limited lead in pipes, solder and flux. Water systems report lead as the 90th percentile of their tap samples, and the average of those results across the city's ZIP codes is below 0.010 mg/L. Because lead in drinking water usually comes from corrosion of a building's own service line and plumbing, that average cannot stand in for a single address.

Historical NFIP Claim Context in Clarks Hill
Historical NFIP data for Clarks Hill contains 1 flood insurance claim. Among claims with payment data, the average reported building, contents, and ICC component sum is $76,125. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The $1,100 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
